Sole Proprietorship Registration in Denmark: Key Requirements

Establishing a business as a sole proprietor in Denmark is a relatively straightforward process, appealing for individuals seeking to unlock the benefits of entrepreneurship in a conducive economic environment. This article provides a comprehensive look at the key requirements for sole proprietorship registration in Denmark, guiding potential business owners through each necessary step.

Understanding Sole Proprietorships

Before diving into the registration details, it is important to understand what a sole proprietorship is. A sole proprietorship is a type of business entity owned and operated by a single individual, who assumes complete control and bears full responsibility for the business operations. This structure is typically favored by small business owners, freelancers, and self-employed individuals due to its simplicity, reduced regulatory burden, and ease of setup.

Benefits of a Sole Proprietorship in Denmark

Starting a sole proprietorship in Denmark offers several advantages:

1. Easy Setup: With minimal bureaucratic requirements, proprietors can quickly establish their business.

2. Full Control: The sole proprietor makes all decisions concerning the business without needing input from partners.

3. Tax Benefits: Sole proprietors can often report their business income on their personal tax returns, potentially lowering their overall tax burden.

Lower Costs: Running a sole proprietorship involves fewer costs compared to other business structures, such as limited liability companies (LLCs).

Key Legal Considerations

To successfully register a sole proprietorship in Denmark, potential business owners must understand the legal landscape surrounding their operations. Key considerations include:

1. Legal Identity: A sole proprietorship does not have a separate legal identity from its owner. This means that personal assets may be at risk should the business face debts or legal issues.

2. Licenses and Permits: Depending on the nature of the business, additional licenses and permits might be required.

3. Business Registration: All businesses in Denmark, including sole proprietorships, must register with the Danish Business Authority (Erhvervsstyrelsen).

Step-by-Step Guide to Registering a Sole Proprietorship

The registration process for a sole proprietorship in Denmark involves several key steps:

1. Decide on a Business Name

Selecting an appropriate business name is the foundational step in establishing a sole proprietorship. The business name should reflect the services or products offered and must be unique-meaning it should not infringe on existing trademarks or company names.

2. Prepare Necessary Documentation

To proceed with the registration, the following documents should be prepared:

- A completed registration form (can be done online)

- Proof of identity (e.g., Danish National ID card or passport)

- Relevant educational or professional certificates if applicable to the business type

- Any documented agreements or contracts relevant to the business operations

3. Register with the Danish Business Authority

Registration can be completed online through the Danish Business Authority's website. The process consists of:

1. Filling out the registration form with the required information, including:

- Business name and address

- Owner's personal information

- Description of business activities

2. Paying the registration fee.

In most cases, the registration fee is modest compared to other forms of business registration and can be paid via various methods, including credit card or online banking.

4. Acquire a Central Business Register (CVR) Number

Upon successful registration, the business will be assigned a Central Business Register (CVR) number, which serves as the unique identification for your business. This number must be included on all official documents, invoices, and contracts.

5. Open a Business Bank Account

After acquiring a CVR number, it is advisable for the proprietor to open a separate business bank account. While not legally required, maintaining a dedicated account for business finances simplifies accounting and tax reporting.

6. Understand Tax Requirements

Sole proprietors in Denmark operate under a simplified taxation structure. Important tax considerations include:

- Income Tax: Profits are taxed as personal income, which is declared through the individual's tax return.

- Value Added Tax (VAT): If the business's annual turnover exceeds DKK 50,000, VAT registration is mandatory.

- Preliminary Income Tax (A Skat): The proprietor may need to pay preliminary income tax based on estimated income throughout the year.

A thorough understanding of tax obligations is crucial for compliance and financial planning.

Important Business Practices Post-Registration

Once the sole proprietorship is registered, there are key practices that should be consistently followed:

1. Maintain Accurate Financial Records

Keeping meticulous financial records is vital for both tax reporting and tracking business performance. It is recommended to use accounting software to streamline the bookkeeping process, ensuring all income and expenses are documented systematically.

2. File Annual Tax Returns

Sole proprietors must file annual tax returns, including the business income. The returns need to report total income, expenses, and applicable deductions. Deadlines for filing vary, so it is crucial to stay informed about tax timelines.

3. Keep Abreast of Regulatory Changes

The regulatory environment can change, impacting tax obligations, licensing requirements, or business practices. Staying vigilant and updated about relevant changes is essential for long-term compliance.

Licenses and Permits

Depending on the specific type of business, sole proprietors may need to obtain various licenses or permits to operate legally in Denmark. Here's a breakdown of common sectors that may require special permits:

1. Trade Licenses

Certain trades, such as those involving construction, healthcare, and finance, require specialized licenses. Individuals should consult the Danish Business Authority or relevant regulatory bodies to identify necessary permits.

2. Environmental Permits

Businesses that may impact the environment, such as manufacturing plants or those dealing with hazardous materials, may require environmental permits.

3. Health and Safety Permits

Businesses in sectors like food service and hospitality should be aware of health and safety regulations, which may require inspections and permits to ensure public safety.

Challenges of Operating a Sole Proprietorship

While the benefits are attractive, it's important to acknowledge potential challenges that may arise when operating as a sole proprietor:

1. Personal Liability

Since there is no legal distinction between personal and business assets, sole proprietors are personally liable for any debts incurred by the business. This can pose significant financial risk.

2. Funding Limitations

Sole proprietorships might find it more challenging to secure funding compared to structured corporations. Many lenders prefer to work with companies that have a formalized structure, such as LLCs or corporations.

3. Limited Growth Potential

Sole proprietors often find growth constrained due to limited resources, capital, and human resources. As the business expands, owners may eventually need to consider transitioning to a different business structure.

Switching to a Different Business Structure

As a business grows, a sole proprietorship might outlive its usefulness as a suitable structure. Transitioning to other forms of business entities, like a limited liability company (LLC), can help limit personal liability and attract investors. Here's how that process generally works:

1. Evaluate the Business Needs

Business owners should assess their current structure, revenue, and future goals to determine if a change is warranted.

2. Consult with Professionals

It is advisable to consult with accountants or legal advisors who can provide insights on the implications of changing business structures.

3. Follow Correct Registration Procedures

Switching requires following the correct legal processes, including registering the new business entity and dissolving the sole proprietorship if necessary.

Tax Obligations and VAT Registration for Sole Proprietors in Denmark

As a sole proprietor in Denmark, you are personally responsible for reporting your business income and paying tax on it through your personal tax return. At the same time, you may also have to register for VAT (moms) and charge VAT on your sales. Understanding how income tax, VAT and reporting deadlines work is essential to avoid penalties and to keep your cash flow under control.

Income tax for sole proprietors

A sole proprietorship is not taxed as a separate legal entity. Instead, the profit from your business is added to your personal income and taxed under the Danish personal tax system. You must report your business result (profit or loss) each year to the Danish Tax Agency (Skattestyrelsen) via your annual tax return.

Your total taxable income is generally split into:

• Personal income (personlig indkomst) – e.g. salary, business profit before capital income
• Capital income (kapitalindkomst) – e.g. interest, some investment income
• Share income (aktieindkomst) – if relevant, for dividends and share gains

Business profit is usually treated as personal income, which is subject to:

• Labour market contribution (AM-bidrag) of 8% on most earned income, including business profit
• Municipal and church tax, which varies by municipality (kommuneskat) and parish, typically totalling around 24–27% combined
• Bottom tax (bundskat) of 12.09% on personal income above the personal allowance
• Top tax (topskat) of 15% on personal income above the top tax threshold

The personal allowance (personfradrag) reduces the income on which you pay bottom and municipal tax. The top tax threshold is set so that only higher incomes pay the 15% top tax. As a sole proprietor, your business profit can therefore push you into the top tax bracket if your total income is high.

Business schemes: personal income vs capital-based taxation

Danish rules allow sole proprietors to choose between different tax schemes for their business income, depending on the size and nature of the business:

• Personal income taxation (personskatteordningen) – the default method where your business profit is taxed as ordinary personal income.
• Business tax scheme (virksomhedsordningen) – allows you to keep business and private finances more clearly separated, deduct interest as business expenses and retain profits in the business at a lower provisional rate before they are withdrawn as personal income.
• Capital-based scheme (kapitalafkastordningen) – allows part of the profit to be treated as capital income instead of personal income, which may be beneficial in some situations.

Choosing the right scheme can significantly affect your total tax bill. The business tax scheme and capital-based scheme have specific bookkeeping and documentation requirements, and you must opt in through your tax return. Many small sole proprietors start with the default personal income taxation and later switch when profits grow.

Preliminary tax (B-income) and on-account payments

Most sole proprietors pay tax as B-income, meaning tax is not withheld automatically as it is for employees. Instead, you pay preliminary tax (forskudsskat) in instalments based on an estimate of your annual profit.

Key points:

• You must submit a preliminary income assessment (forskudsopgørelse) to Skattestyrelsen with an estimate of your expected business profit for the year.
• Based on this, the tax authority calculates your preliminary tax and splits it into instalments, typically paid throughout the year.
• If your actual profit is higher or lower than expected, you should update your preliminary assessment to avoid large underpayments or overpayments.
• After the end of the year, you file your final tax return (årsopgørelse). Any difference between preliminary and final tax is settled – you may receive a refund or have to pay additional tax, possibly with interest.

VAT (moms) registration threshold and obligations

In Denmark, you must register for VAT if your business has, or is expected to have, a turnover of more than DKK 50,000 over a 12‑month period from VAT‑liable activities. This threshold applies to the total taxable turnover, not just profit.

You must register for VAT no later than 8 days before you start VAT‑liable activities or expect to exceed the threshold. Registration is done via the Danish Business Authority’s online system (Virk) and is linked to your personal CPR and business CVR number.

Once registered, you must:

• Charge VAT on your sales of goods and services that are not exempt
• Issue invoices that meet Danish VAT invoice requirements
• Keep proper VAT accounts and documentation for all sales and purchases
• Submit VAT returns and pay VAT to Skattestyrelsen by the relevant deadlines

Standard VAT rate and special rates

Denmark has a relatively simple VAT system with one main rate:

• Standard VAT rate: 25% on most goods and services

There are no reduced VAT rates (such as 5% or 10%) as in some other EU countries. However, some activities are exempt from VAT, including for example certain financial services, health care services, education and some cultural activities. If your activity is VAT‑exempt, you do not charge VAT on your sales, but you also cannot deduct input VAT on your purchases related to those exempt activities.

VAT periods and filing deadlines

The frequency of your VAT reporting depends on your turnover. For most new and smaller sole proprietors, VAT is reported quarterly, but the rules can change as your turnover grows.

Typical VAT periods are:

• Half-yearly – for very small businesses with low turnover
• Quarterly – for many small and medium-sized businesses
• Monthly – for businesses with higher turnover

Skattestyrelsen will assign you a VAT period when you register. You must submit your VAT return and pay any VAT due by the deadline stated in your online tax account (TastSelv Erhverv). Deadlines usually fall about one month after the end of the VAT period, but you should always check the exact dates in your tax account.

Input VAT deduction

As a VAT‑registered sole proprietor, you can deduct the VAT you pay on goods and services purchased for your business (input VAT) from the VAT you collect on your sales (output VAT). You only pay the difference to Skattestyrelsen.

Important conditions for deducting input VAT:

• The purchase must be used for your VAT‑liable business activities
• You must have a valid invoice with the supplier’s CVR number and VAT amount
• For mixed use (both private and business), you may only deduct the business‑related portion
• Certain expenses, such as some types of entertainment, have limited or no VAT deductibility

If your input VAT exceeds your output VAT in a period, you can usually get a VAT refund from Skattestyrelsen after filing your VAT return.

VAT and cross-border activities within and outside the EU

If you sell to customers in other EU countries or outside the EU, special VAT rules apply:

• Sales of services to business customers (B2B) in the EU are often subject to the reverse charge mechanism, where the customer accounts for VAT in their own country. You must include the customer’s VAT number on the invoice and report the sale in EU sales listings if required.
• Sales of digital services and certain goods to private consumers (B2C) in other EU countries may require you to use EU VAT schemes such as the One‑Stop Shop (OSS) if you exceed EU‑wide thresholds.
• Exports to customers outside the EU are generally zero‑rated for Danish VAT, but you must keep documentation proving that the goods or services were exported.

Cross‑border VAT rules are complex, and incorrect treatment can lead to back payments and penalties, so it is often advisable to seek professional guidance if you plan to trade significantly with foreign customers.

Bookkeeping and documentation for tax and VAT

To meet your tax and VAT obligations, you must keep accurate and up‑to‑date records of all business income and expenses. Danish bookkeeping rules require you to:

• Record all transactions systematically and without undue delay
• Store accounting records, invoices and supporting documents for at least 5 years
• Be able to document how you calculated your taxable profit and VAT

Digital bookkeeping solutions are widely used and make it easier to prepare VAT returns and annual accounts. Good bookkeeping also helps you estimate your preliminary tax more accurately.

Common mistakes and how to avoid them

Sole proprietors in Denmark often run into problems with:

• Failing to register for VAT on time when approaching the DKK 50,000 turnover threshold
• Not setting aside enough funds for income tax and VAT, leading to cash‑flow issues
• Mixing private and business expenses, making it hard to document deductions
• Missing VAT or tax deadlines and incurring interest and penalties

You can reduce these risks by monitoring your turnover regularly, using separate bank accounts for business and private finances, updating your preliminary tax assessment when your income changes, and setting calendar reminders for VAT and tax deadlines.

Professional assistance and digital tools

While many small sole proprietors handle basic tax and VAT tasks themselves using Skattestyrelsen’s online services, professional accounting support can be valuable, especially when:

• Your turnover grows and VAT reporting becomes more complex
• You consider using the business tax scheme or capital‑based scheme
• You start trading with foreign customers or suppliers

An accountant or tax adviser familiar with Danish rules can help you optimise your tax position, avoid errors and ensure that your sole proprietorship remains compliant with all current tax and VAT regulations.

Social Security, ATP and Pension Contributions for Sole Traders

As a sole proprietor in Denmark, you are personally responsible for your own social security, ATP and pension savings. Unlike employees, you do not have an employer who automatically pays labour market contributions or sets up a workplace pension for you. Understanding how these systems work helps you avoid gaps in coverage and plan for retirement in a tax-efficient way.

Social security and labour market contributions (AM-bidrag)

Danish social security for sole traders is primarily financed through the mandatory labour market contribution (arbejdsmarkedsbidrag, AM-bidrag) and general income tax. AM-bidrag is a flat 8% contribution calculated on your business profit and other earned income before income tax. You pay it together with your income tax via your annual tax return and preliminary tax assessment.

As a sole proprietor, you are generally covered by the Danish social security system on the same terms as employees if you are tax resident in Denmark and pay tax here. This typically gives you access to public healthcare, child benefits, state pension (folkepension) and other basic social benefits, provided you meet the usual residence and qualifying conditions.

However, there are important differences compared with employees:

• You are not automatically covered by employer-funded schemes such as occupational injury insurance, health insurance or employer pension contributions.
• You must actively arrange your own insurance and pension if you want coverage beyond the basic public system.
• Your entitlement to certain benefits (for example sickness benefits) may depend on your reported business income and the way you pay tax.

Sickness, maternity and unemployment coverage

Self-employed persons can be entitled to public sickness and maternity benefits, but the rules differ from employees and often require advance registration or voluntary schemes. Your right to benefits and the compensation you receive usually depend on:

• How long you have run your business
• Your documented business income
• Whether you have joined any voluntary insurance schemes for self-employed

Unemployment insurance is not automatic. If you want protection in case your business income stops, you must join an unemployment insurance fund (a-kasse) that accepts self-employed members and comply with their rules on working hours, income documentation and availability for work.

ATP contributions for sole traders

The Danish Labour Market Supplementary Pension (Arbejdsmarkedets Tillægspension, ATP) is a statutory pension scheme that employees and employers pay into. For employees, contributions are shared between employer and employee and deducted directly from salary.

As a sole proprietor, you are not automatically covered by ATP through your business activity. You may pay ATP in other roles (for example if you also have a part-time job as an employee), but your self-employed income does not in itself trigger ATP contributions.

For most sole traders, this means:

• You will receive ATP only for periods where you have been employed and ATP contributions were paid.
• Your self-employed years will not increase your ATP unless you are covered through other employment or specific voluntary arrangements.
• You should consider building your own private or occupational-style pension to compensate for the lack of ATP contributions from your business activity.

Public pension vs. private pension for sole proprietors

All residents who meet the qualifying conditions are entitled to the Danish state pension (folkepension) from the official retirement age, which is gradually increasing and depends on your year of birth. The state pension consists of a basic amount and a pension supplement that is income-tested. This pension is financed through general taxation, not through a specific contribution from your business.

Because the state pension and any ATP you may have from previous employment are rarely enough to maintain your standard of living, most sole proprietors need additional pension savings. You can set up private pension schemes that are tailored to self-employed persons and that often provide tax advantages.

Main pension schemes available to sole traders

As a sole proprietor, you can use the same main types of pension products as employees, but you pay the contributions yourself. The most common are:

• Rate pension (ratepension) – pays out in instalments over a fixed period (typically 10–30 years). Contributions are usually deductible from your personal income up to an annual limit set by law. The limit is adjusted regularly, so you should check the current maximum deductible amount before deciding your contribution level.
• Lump-sum pension (aldersopsparing) – pays out as one or several lump sums. Contributions are not deductible, but the payout is usually tax-free. There is an annual contribution ceiling and a lifetime maximum; exceeding these limits can trigger extra tax.
• Life annuity (livrente) – pays a lifelong pension. Contributions are typically fully deductible from personal income without the same strict annual cap as a rate pension, but the product is more long-term and less flexible.

Pension contributions are normally paid from your after-business-profit income. You deduct them in your personal tax return, which reduces your taxable income and can lower both AM-bidrag and income tax, depending on the scheme and tax rules in force.

Tax treatment of pension contributions for sole proprietors

Pension rules are detailed and change regularly, but some general principles apply:

• Contributions to deductible pension schemes (for example rate pension and life annuity) reduce your taxable personal income within the statutory limits.
• Contributions to non-deductible schemes (for example lump-sum pension) do not reduce your current tax, but the payout is usually tax-free or taxed favourably.
• Investment returns inside pension schemes are subject to a special pension yield tax (PAL-skat), which is lower than the top marginal tax on personal investment income.

Because your business profit can fluctuate from year to year, it can be tax-efficient to adjust your pension contributions annually. In high-income years, larger deductible contributions can help you avoid or reduce top-bracket tax, while in lower-income years you may choose smaller contributions or focus on non-deductible savings.

Practical steps to arrange pension as a sole trader

To build a solid pension as a sole proprietor, consider the following steps:

1. Estimate your expected annual business profit and personal income, including any salary from employment.
2. Decide how much you can allocate to long-term savings without harming your business liquidity.
3. Choose one or more pension products (rate pension, lump-sum pension, life annuity) based on your age, risk tolerance and desired payout pattern.
4. Set up a pension agreement with a bank, pension company or insurance provider that offers solutions for self-employed.
5. Arrange automatic monthly or quarterly payments from your business or personal account to avoid missing contributions.
6. Review your pension plan annually together with your accountant to ensure you use the current tax rules and contribution limits efficiently.

Coordinating social security, ATP and pension with other income

Many sole proprietors in Denmark combine self-employment with a regular job. In that case, you may already have ATP contributions and an employer-funded pension from your employment. Your business pension planning should then complement, not duplicate, these schemes.

Key points to consider if you are both employed and self-employed:

• Your ATP from employment continues as usual; your self-employed income does not change those contributions.
• Employer pension contributions count towards certain overall tax limits, so your own deductible contributions from business income must be coordinated to avoid exceeding the allowed maximum.
• Your total income (salary plus business profit) determines your marginal tax rate and therefore the tax value of pension deductions.

Why professional advice is important

Danish rules on social security, ATP and pension contributions for sole traders are complex and interact closely with your tax situation, family circumstances and long-term plans. Before making large pension commitments or assuming you are fully covered by the public system, it is advisable to:

• Discuss your situation with an accountant who understands self-employed taxation
• Obtain a pension analysis from a bank or pension provider
• Check your current ATP and state pension projections through the official digital self-service portals

By actively managing your social security coverage, ATP status and pension contributions from the start of your sole proprietorship, you reduce financial risk and build a more secure retirement, while at the same time using the Danish tax rules to your advantage.

Choosing a Business Name and Branding Rules under Danish Law

Choosing the right business name is one of the first legal decisions you make when registering a sole proprietorship in Denmark. Your name must comply with Danish business law and the rules of the Danish Business Authority (Erhvervsstyrelsen), and it should also work well for marketing and online visibility.

Legal forms of business names for sole proprietors

As a sole proprietor, you can operate under your own personal name or under a separate business name (a “secondary name” or bibrand). In practice, most sole traders register a distinct business name to build a brand and appear more professional to customers and partners.

The registered business name will appear in the Central Business Register (CVR) and on official documents. You may also register additional secondary names if you run different product lines or activities under the same CVR number.

Mandatory elements and identification

Danish law does not require a specific legal suffix such as “ApS” or “A/S” for sole proprietorships, and you must not use such endings because they are reserved for limited liability companies. Your business name must clearly not give the impression that you run an incorporated company or that you have limited liability if this is not the case.

On invoices, contracts, your website and other business documents, you must clearly state:

• Registered business name as listed in CVR
• Your CVR number
• Your physical address or registered business address

This information helps customers and authorities identify your business and is part of your basic legal obligations as a trader in Denmark.

Prohibited and misleading names

The Danish Business Authority will reject names that are misleading or contrary to law and good practice. In particular, you may not choose a name that:

• Suggests a different legal form (for example, using “ApS”, “A/S” or “IVS” when you are a sole proprietor)
• Implies public authority status or official approval that you do not have (for example, “Statens”, “Kommunal”, “Officiel kontrol”)
• Is offensive, discriminatory or clearly contrary to public order or good morals
• Is likely to mislead about the nature, scope or geographical origin of your business

If the authority considers your name misleading or unlawful, you will be asked to change it before registration is completed.

Uniqueness and conflicts with existing names

Your business name must be distinguishable from names already registered in the CVR register. When you apply for registration, the system checks for identical or almost identical names. If there is a conflict, you will need to adjust your name, for example by changing words, adding a distinctive element or choosing a different brand altogether.

Even if the name is accepted in CVR, you can still run into conflicts with existing trademarks or established business names. Another company that has used a similar name for the same type of goods or services can demand that you stop using your name if it creates confusion in the market. This is regulated by the Danish Trade Marks Act and the Danish Marketing Practices Act.

Checking trademarks and domain names

Before you register your sole proprietorship, it is wise to check whether your desired name or logo is already protected as a trademark. You can search:

• The Danish Patent and Trademark Office database for national trademarks
• EUIPO (European Union Intellectual Property Office) for EU trademarks
• WIPO databases for international registrations that cover Denmark

At the same time, check whether a suitable domain name is available, especially a .dk domain. The Danish Internet Forum (DK Hostmaster) manages .dk domains, and many customers in Denmark expect local businesses to use a .dk address. Aligning your registered business name, trademark and domain name strengthens your brand and reduces the risk of legal disputes.

Language, special characters and practical considerations

Danish business names may include Danish letters (æ, ø, å) and most standard Latin characters. However, for branding and online search, it is often practical to choose a name that is easy to spell and pronounce for both Danish and international customers. Avoid overly long or complicated names and be careful with special characters that may cause issues in email addresses, URLs or foreign systems.

You may use English words or foreign-language elements in your name as long as the name is not misleading and complies with Danish law. If you plan to sell primarily to Danish consumers, consider whether the name clearly communicates what you do and is easy to remember in Danish.

Using descriptive and protected words

Descriptive words such as “consulting”, “cleaning” or “web design” can be part of your name, but purely descriptive names are harder to protect legally. If you want stronger protection, combine descriptive elements with a distinctive word or invented brand name.

Certain words and terms are restricted or sensitive. For example, words suggesting regulated professions (such as “advokat”, “revisor” or “læge”) may only be used if you actually hold the relevant authorization and operate within the legal framework for that profession. Using such terms without the proper qualifications can be considered misleading marketing and may lead to sanctions.

Branding rules and marketing law

Once your name is registered, all your branding and marketing must comply with the Danish Marketing Practices Act. This means your business name, logo, slogans and advertising cannot be misleading, must respect competitors’ rights and must be clearly commercial when you communicate with consumers online.

If you use endorsements, comparisons with competitors or environmental claims (for example, “climate neutral” or “CO₂-free”), you must be able to document them. Your brand identity must not create a risk of confusion with existing brands, and you must respect copyright in logos, fonts, images and other design elements.

Changing your business name later

You can change the registered name of your sole proprietorship after registration by updating your information with the Danish Business Authority. The new name must meet the same legal requirements and will appear in CVR once approved. Remember to update your invoices, website, social media, contracts, signage, domain registrations and any trademark registrations to reflect the new name.

Practical steps when choosing a name

1. Brainstorm several name options that reflect your services and target customers
2. Check availability in the CVR register to avoid conflicts with existing businesses
3. Search trademark databases to identify potential rights conflicts
4. Check domain availability, especially .dk, and secure relevant domains
5. Review whether the name is easy to pronounce, spell and remember in Danish
6. Ensure the name does not suggest a different legal form or official status
7. Register the chosen name with the Danish Business Authority and use it consistently in all branding

By following these steps and respecting Danish naming and branding rules, you reduce legal risk and build a strong, credible identity for your sole proprietorship from day one.

Digital Requirements: NemID/MitID, e-Boks and Communication with Authorities

Running a sole proprietorship in Denmark is highly digital. Most communication with public authorities is online, and you are expected to use MitID (which has replaced NemID), e-Boks and various self-service portals. Understanding these tools is essential for registering your business, filing taxes and staying compliant.

MitID: your digital ID for business and private use

MitID is the primary digital identification solution in Denmark and is required for almost all interactions with Danish authorities. As a sole proprietor, you typically use the same MitID for both private and business purposes, because the business is not a separate legal entity from you personally.

You will normally need MitID to:

• Register your sole proprietorship with the Danish Business Authority (Virk.dk)
• Log in to Skat (TastSelv Erhverv and TastSelv Borger) to manage taxes and VAT
• Access your digital mailbox (e-Boks or mit.dk)
• Sign digital documents and agreements with banks, insurance companies and other partners

If you do not yet have MitID, you must obtain it before you can complete most registration and reporting tasks. Foreign residents usually need a Danish CPR number and may also need to verify their identity at a citizen service centre or via their bank.

NemID for businesses: legacy access and transition

NemID has largely been phased out and replaced by MitID. However, some older systems and foreign guidance may still refer to NemID or NemID employee signatures. When you see these terms, you should assume that MitID is now the relevant solution.

If you previously used NemID for business, you are expected to migrate to MitID. In practice, this means:

• Ensuring you have an active MitID that can be used for business self-service solutions
• Updating any internal procedures or manuals that still mention NemID
• Checking that your bank and other providers have switched your login method to MitID

e-Boks and digital mail from authorities

In Denmark, most official letters are sent as digital mail. As a sole proprietor, you are required to receive and read digital messages from authorities such as the Danish Tax Agency (Skattestyrelsen), the Danish Business Authority (Erhvervsstyrelsen), municipalities and other public bodies.

Digital mail is usually delivered to:

• Your private digital mailbox (e-Boks or mit.dk), linked to your CPR number
• Any additional business mailbox you may have set up

Because a sole proprietorship is not a separate legal person, many important business messages are sent to your personal digital mailbox. It is your responsibility to log in regularly and read everything, including messages in Danish. Deadlines for tax returns, VAT reporting, payment reminders and documentation requests are often communicated only via digital mail.

Registering and managing your business on Virk.dk

Virk.dk is the central portal for business self-service in Denmark. You use it to register your sole proprietorship and to access forms and services from multiple authorities.

Key tasks you can perform on Virk.dk include:

• Registering your sole proprietorship (including VAT registration if required)
• Updating business details such as address, industry code (branchekode) and contact information
• Registering as an employer if you hire staff
• Reporting statistics or sector-specific information if requested

Access to Virk.dk services is normally via MitID. Make sure that your contact email and phone number in the business registration are up to date, as authorities may use them for notifications and reminders.

Digital communication with the Danish Tax Agency (Skattestyrelsen)

Most tax-related tasks for sole proprietors are handled digitally through the TastSelv systems:

• TastSelv Borger for your personal income tax, preliminary income assessment and annual tax return
• TastSelv Erhverv for VAT, payroll taxes and other business-related reporting

With MitID you can:

• Register or deregister for VAT and payroll taxes
• Submit VAT returns and pay VAT due
• Report A-income and AM-contributions if you have employees
• View payment deadlines, outstanding balances and payment details
• Send secure messages to Skattestyrelsen and receive replies in your digital mailbox

Authorities expect you to use these digital channels. Paper forms and physical letters are rarely accepted and may lead to delays or non-compliance if you do not use the online systems.

Language, notifications and practical tips

Most public digital interfaces and letters are in Danish. Some portals offer partial English versions, but critical information, legal texts and system messages are often only in Danish. As a sole proprietor, you should:

• Log in to your digital mailbox and tax portals regularly, not just when you expect a message
• Enable email or SMS notifications where available, so you are alerted when new digital mail arrives
• Use professional translation or local advisory support if you are not comfortable with Danish

Ignoring digital mail or missing deadlines because you did not check your e-Boks is not accepted as a valid excuse by Danish authorities. Timely digital communication is considered part of your basic compliance obligations.

Data security and access control

Because MitID gives access to both your personal and business information, you must protect it carefully. Do not share your MitID login with employees, bookkeepers or external consultants. If you need others to help with your accounting or tax reporting, consider:

• Granting them limited access via authorised representative solutions where available
• Signing separate agreements with your accountant to define responsibilities and data handling
• Keeping clear internal records of who has access to which systems and for what purpose

Maintaining secure and organised digital access is an important part of running a compliant and professional sole proprietorship in Denmark.

Bookkeeping Standards and Record-Keeping Obligations in Denmark

As a sole proprietor in Denmark, you are legally required to keep orderly and reliable accounts. Proper bookkeeping is not only a compliance obligation under the Danish Bookkeeping Act and the Tax Control Act, but also the basis for correct tax, VAT and social contribution calculations. Even if your business is small, the Danish Tax Agency (Skattestyrelsen) expects you to be able to document all income and expenses with clear, traceable records.

Who must keep accounts and what is covered

All sole proprietorships that carry out business activities in Denmark must keep bookkeeping records, regardless of turnover. This applies whether you are VAT-registered or not, and whether you run the business full-time or part-time alongside employment. Your bookkeeping must cover at least:

• All sales and other income (including cash, bank transfers, card payments and online platform income)
• All business expenses (purchases, rent, subscriptions, professional services, mileage and other operating costs)
• Assets and liabilities related to the business (equipment, inventory, loans, deposits)
• VAT, payroll taxes (if you have employees) and other duties you are liable for

Basic bookkeeping principles in Denmark

Danish rules require that your bookkeeping is timely, accurate and verifiable. In practice this means:

• Ongoing registration: Transactions should be recorded on a continuous basis and without undue delay. Waiting until year-end to “reconstruct” your accounts is not acceptable.
• Traceability: Every entry must be traceable from the source document (invoice, receipt, bank statement) to the bookkeeping record and, if relevant, to your annual tax return and VAT returns.
• Completeness: All business-related transactions must be included. Private expenses must be kept separate and may not be deducted unless they qualify as mixed-use expenses under specific rules.
• Consistency: You must apply consistent accounting principles from year to year, for example how you depreciate equipment or treat small assets.
• Documentation: Each entry must be supported by adequate documentation in case of a tax or VAT audit.

Digital bookkeeping and use of accounting systems

Danish law increasingly favours digital bookkeeping. While very small sole proprietors can still keep manual records, using a digital accounting system that complies with Danish standards is strongly recommended and, for many businesses, practically necessary. A suitable system should allow you to:

• Record income and expenses with date, amount, VAT code and description
• Attach or link digital copies of invoices and receipts
• Reconcile your accounts with bank statements
• Generate VAT statements and basic financial reports

From the perspective of Skattestyrelsen, digital records are fully acceptable as long as they are secure, complete, readable and can be exported on request. If you use foreign or cloud-based software, ensure that data can be made available to Danish authorities without delay.

Requirements for invoices and documentation

Every business transaction must be supported by proper documentation. For sales, this is usually an invoice or receipt; for purchases, it is a supplier invoice, receipt or contract. Danish rules require that invoices contain at least:

• Your business name and address
• Your CVR number if you are VAT-registered
• The customer’s name and address (for B2B and larger B2C sales)
• Invoice date and a unique, sequential invoice number
• Description of goods or services supplied
• Quantity and unit price
• Total amount, indicating whether VAT is included or added
• The applicable VAT rate (normally 25%) and the VAT amount, or a reference to VAT exemption where relevant

For small cash sales to private customers, a simplified receipt may be acceptable, but you must still be able to document total daily takings, for example via a cash register report or point-of-sale system.

Separation of business and private finances

Although a sole proprietorship is not a separate legal entity, Danish practice strongly recommends separating business and private finances. Using a dedicated business bank account and business payment solutions makes it easier to:

• Document business income and expenses
• Avoid mixing private and business transactions
• Prepare tax and VAT returns
• Handle audits and questions from Skattestyrelsen

If you do use a private account for business, you must be able to clearly identify and document all business-related transactions, which can be time-consuming and risky in case of an audit.

Record-keeping periods and storage rules

Under Danish law, you must store your accounting records and supporting documentation for at least five years after the end of the financial year they relate to. This retention period applies to:

• Bookkeeping records and ledgers
• Invoices issued and received
• Receipts, contracts and agreements
• Bank statements and payment confirmations
• VAT returns and documentation for VAT calculations
• Payroll records if you have employees

Records may be stored digitally, physically or in a combination of both, as long as they remain readable, complete and accessible throughout the entire retention period. If you store data electronically, you must ensure proper backup and protection against loss or unauthorised access, in line with data protection rules.

Bookkeeping period and financial year

Most Danish sole proprietors use the calendar year as their financial year, but you can choose a different 12-month period if it suits your business and is accepted by Skattestyrelsen. Regardless of the chosen year, your bookkeeping must cover the entire period without gaps. At the end of each financial year, you should prepare a simple set of accounts showing:

• Total income and expenses for the year
• Profit or loss from the business
• Assets and liabilities at year-end

These figures form the basis for your personal tax return and, if applicable, your annual VAT reconciliation.

Cash, card and online payments

If you receive cash payments, you must keep a daily cash record that shows opening balance, cash sales, other cash income, cash expenses and closing balance. Differences between the calculated and actual cash balance must be explained and recorded. For card and online payments, you should reconcile your bookkeeping with:

• Bank statements
• Payment service provider reports (e.g. from card acquirers or online platforms)
• Sales reports from your webshop or POS system

Skattestyrelsen often compares such data during audits to verify that all income has been reported.

VAT-related bookkeeping requirements

If your annual turnover exceeds the Danish VAT registration threshold, or if you voluntarily register for VAT, you must keep VAT-specific records that clearly show:

• Output VAT on your sales
• Input VAT on your purchases
• Adjustments, credit notes and corrections
• VAT-free or exempt sales, if applicable

Your bookkeeping system should allow you to allocate each transaction to the correct VAT code so that your periodic VAT returns can be prepared accurately. You must be able to reconcile the figures in your VAT returns with your underlying bookkeeping and documentation.

Language and currency of records

Bookkeeping may be kept in Danish, Norwegian, Swedish or English. If you use another language, Skattestyrelsen can require you to provide translations of key documents. Amounts can be recorded in foreign currency for operational purposes, but for tax and VAT reporting you must convert to Danish kroner (DKK) using acceptable exchange rates.

Consequences of poor bookkeeping

Failure to comply with Danish bookkeeping and record-keeping obligations can lead to serious consequences, including:

• Estimated tax and VAT assessments based on Skattestyrelsen’s discretion
• Interest and surcharges on underpaid tax or VAT
• Administrative fines for missing or inadequate records
• In severe or repeated cases, criminal penalties

Maintaining proper bookkeeping from the start is usually far less costly than trying to reconstruct missing records later or disputing estimated assessments.

Working with a Danish accountant or bookkeeper

Many sole proprietors in Denmark choose to work with a professional accountant or bookkeeper, at least for setting up a compliant system and preparing annual accounts. A local specialist can help you:

• Choose and configure a bookkeeping system that meets Danish requirements
• Set up invoice templates and VAT codes correctly
• Establish routines for handling receipts, bank reconciliation and cash
• Prepare year-end accounts and ensure that your tax and VAT filings match your records

Even if you handle daily bookkeeping yourself, periodic reviews by a professional can reduce the risk of errors and give you more confidence that your sole proprietorship complies with Danish bookkeeping and record-keeping rules.

Income Tax Calculation, Deductions and Allowable Business Expenses

As a sole proprietor in Denmark, your business income is taxed as personal income. You do not pay corporate tax, but instead report your profit on your personal tax return and pay income tax, labour market contributions and, where relevant, church tax. Understanding how your taxable income is calculated and which expenses you can deduct is essential to avoid overpaying tax and to stay compliant.

How income tax for sole proprietors is structured

Danish tax on business income is progressive and consists of several layers. As a sole trader, you are typically subject to:

• Labour Market Contribution (AM-bidrag) of 8% on your business profit before other income taxes
• Municipal tax, which varies by municipality but is usually around 24–27% of your taxable income after AM-bidrag
• Health contribution replacement in municipal tax (already integrated in the municipal rate)
• State tax:
  • Bottom-bracket state tax on most taxable income
  • Top-bracket state tax of 15% on personal income above the top tax threshold
• Church tax of around 0.4–1.3% if you are a member of the Danish National Church

The top-bracket state tax applies only to the part of your personal income that exceeds the annual top tax threshold set by the Danish Parliament. When all layers are combined, the effective marginal tax on income above the top threshold can approach the statutory maximum of 52.07%, excluding AM-bidrag.

Standard business taxation vs. business tax schemes

Most small sole proprietors are taxed under the standard rules for personal income. However, you can opt into specific business tax schemes that may be beneficial depending on your profit level and private finances:

• Standard personal taxation: your business profit is treated as personal income. Interest expenses and certain other items are treated as capital income. This is the default if you do not choose a special scheme.
• Business Tax Scheme (Virksomhedsordningen): allows you to:
  • Deduct business interest expenses against business income instead of capital income
  • Retain part of the profit in the business at a flat business tax rate similar to the corporate tax rate, and tax it later when withdrawn
  • Separate business and private finances more clearly for tax purposes
• Capital Return Scheme (Kapitalafkastordningen): allows you to treat a calculated return on your business assets as capital income instead of personal income, which can reduce top-bracket tax in some situations.

Choosing a scheme is optional but must be done consistently for the whole income year and reported correctly in your tax return. Changing schemes later can have tax consequences, so it is advisable to get professional advice before opting in.

Calculating taxable profit as a sole proprietor

Your taxable business profit is generally calculated as:

Business revenue – allowable business expenses – tax depreciation = taxable profit

Business revenue includes all income from your activity, such as sales of goods and services, commissions, fees and other business-related income. Private income (for example, salary from employment or private investment income) is reported separately and taxed under different rules.

Allowable business expenses

You can deduct expenses that are incurred solely to earn, secure and maintain your business income. The expense must be directly related to your business activity and properly documented with invoices, receipts or contracts. Typical deductible expenses include:

• Office and workspace costs: rent for business premises, shared office fees, utilities for business premises, cleaning and minor maintenance
• Equipment and tools: computers, phones, software licences, machinery, tools and other equipment used in the business
• Supplies and materials: goods for resale, raw materials, packaging, office supplies
• Professional services: accounting, bookkeeping, legal advice, business consulting directly related to your activity
• Marketing and sales: website costs, hosting, online advertising, printed materials, trade fair participation, business cards
• Travel and transport: business trips, mileage allowance for using a private car for business, public transport tickets for business travel
• Insurance: business liability insurance, professional indemnity insurance, insurance for business assets
• Telecommunications: business phone subscriptions, internet connection used for the business
• Bank and payment fees: fees for business accounts, payment terminals, online payment solutions
• Education and courses: continuing professional training directly related to your current business

Expenses with both private and business use must be split, and only the business-related part is deductible. You must be able to justify the allocation if the tax authorities ask.

Depreciation of assets

Larger assets that are used over several years cannot usually be deducted in full in the year of purchase. Instead, they are depreciated over time according to Danish tax rules. Common examples include:

• Machinery and equipment
• IT hardware and certain software
• Vehicles used for business
• Fittings and installations in rented premises

Depreciation is typically calculated using declining-balance or straight-line methods, with maximum annual rates set by law for different asset categories. You keep a tax depreciation schedule and deduct the annual depreciation amount as an expense. When you sell or scrap an asset, you may have a taxable gain or a deductible loss depending on the remaining tax value.

Car and transport expenses

If you use your private car for business purposes, you can normally choose between:

• Standard mileage allowance at the official Danish kilometre rates up to a certain annual distance, and a lower rate above that distance
• Actual costs, where you deduct the business share of fuel, insurance, repairs, tyres, financing and depreciation

You must keep a detailed logbook if you want to deduct mileage or actual car costs. If the car is registered in the business, different rules apply for private use, and there may be a taxable benefit if you use the car privately.

Home office and mixed-use expenses

If you work from home, you may be able to deduct a portion of your housing costs if a clearly separated part of the home is used exclusively and regularly for business. The deduction is often calculated based on the proportion of square metres used for business compared to the total home area. Expenses that can be split include:

• Rent or interest and property taxes (for owners)
• Electricity, heating and water
• Home insurance, if it covers the business area

If the space is not used exclusively for business (for example, a dining table used as a desk), the deduction is usually not accepted. Instead, you may deduct specific business-related costs such as office furniture and equipment.

Meals, representation and entertainment

Expenses for client entertainment and representation are only partly deductible. Danish tax rules limit the deduction for restaurant visits, events and similar costs aimed at maintaining or establishing business relations. You must keep detailed documentation showing the business purpose, participants and date. Purely private entertainment and meals are not deductible.

Non-deductible and limited-deduction expenses

Certain expenses are not deductible or only partly deductible, even if they are connected to your business. Examples include:

• Private living costs (rent for your private home, private food, clothing not specifically required for work)
• Fines and penalties
• Private health insurance not structured as a business scheme
• Depreciation above the legal maximum rates
• Representation expenses beyond the allowed percentage

Mixing private and business expenses on the same bank account or card makes it harder to prove deductions and increases the risk of corrections during a tax audit.

Prepayments, reporting and deadlines

As a sole proprietor, you usually pay tax on account during the year based on expected profit, and then settle the final tax when your annual assessment is issued. Key points include:

• You must register your business with the Danish Business Authority and the tax authorities before starting taxable activity
• You report your business result in the annual tax return, using the specific forms for self-employed income
• You can adjust your preliminary income assessment during the year if your profit is higher or lower than expected, to avoid large back payments or overpayments
• Interest and surcharges may apply if you underpay and do not adjust your preliminary tax in time

Record-keeping obligations

To support your deductions and tax calculations, you must keep orderly accounts and documentation. In Denmark, business records, including invoices, contracts, bank statements and bookkeeping records, must generally be kept for at least five years. Digital bookkeeping systems that comply with Danish requirements make it easier to:

• Separate business and private transactions
• Track deductible expenses and depreciation
• Prepare VAT returns if you are VAT-registered
• Provide documentation quickly in case of a tax audit

Optimising your tax position legally

Within the Danish rules, there are several ways to optimise your tax burden without taking unnecessary risks:

• Choosing the right tax scheme (standard, Business Tax Scheme or Capital Return Scheme) based on your profit level and private income
• Planning investments in equipment and assets to make best use of depreciation rules
• Ensuring all legitimate business expenses are documented and claimed
• Considering pension contributions and other long-term planning tools that can reduce taxable income

Because Danish tax rules are detailed and change periodically, many sole proprietors work with a professional accountant to ensure correct calculations and to make full use of available deductions and schemes.

Hiring Employees as a Sole Proprietor: Payroll, Holiday Pay and Insurance

As a sole proprietor in Denmark, you are allowed to hire employees just like any other business. However, once you become an employer, you take on a range of legal obligations related to payroll, tax withholding, holiday pay, social contributions and mandatory insurance. Understanding these rules from the start helps you avoid penalties and unexpected costs.

Registering as an employer (eIndkomst and E-income)

Before paying any salary, you must register as an employer with the Danish Tax Agency (Skattestyrelsen) via Virk.dk. This gives you access to the eIndkomst (E-income) system, where you report all salary payments, A-tax (income tax withholding) and labour market contributions (AM-bidrag).

Key points when registering as an employer:

• You must have a CVR number for your sole proprietorship
• You must register before the first salary payment
• All salary, benefits and reimbursements to employees must be reported digitally to eIndkomst

Payroll basics: A-tax, AM-bidrag and reporting deadlines

As an employer, you are responsible for withholding and paying your employees’ income tax and labour market contributions. The two main elements are:

• AM-bidrag (labour market contribution): 8% of the gross salary before income tax
• A-tax (withholding tax): calculated based on the employee’s tax card, tax rate and personal allowances

Payroll process in practice:

1. Calculate gross salary for the period, including any supplements and benefits in kind
2. Withhold 8% AM-bidrag from the gross salary
3. Calculate A-tax on the salary after AM-bidrag, using the employee’s tax card
4. Pay the net salary to the employee
5. Report salary, AM-bidrag and A-tax to eIndkomst and pay the withheld amounts to Skattestyrelsen

Reporting and payment deadlines depend on your size and whether you are a new employer, but for most small sole proprietors payroll reporting and payment are monthly. Late reporting or payment can lead to interest and penalties, so it is important to set up a clear payroll routine or use a payroll system.

Holiday pay (feriepenge) and the Danish Holiday Act

Employees in Denmark are covered by the Danish Holiday Act (Ferieloven), which gives them the right to paid holiday. As an employer, you must calculate and set aside holiday pay for your employees.

Under the current concurrent holiday system, employees earn and can take holiday at the same time. The standard rules are:

• Employees earn 2.08 days of paid holiday per month of employment, up to 25 days per holiday year
• Holiday pay is normally 12.5% of the employee’s holiday-qualifying salary

How you handle holiday pay depends on whether the employee receives a fixed monthly salary or is paid by the hour:

• Monthly-paid employees: Typically receive their normal salary during holiday, plus a holiday supplement (ferietillæg), usually at least 1% of the holiday-qualifying salary, unless a collective agreement or contract specifies a higher rate
• Hourly-paid employees: Usually accrue 12.5% holiday pay, which you pay to FerieKonto or another approved holiday fund each month

You must report holiday pay correctly and ensure that amounts are transferred to the relevant holiday scheme (FerieKonto or a collective agreement fund) within the applicable deadlines. Failure to do so can result in claims from employees and possible fines.

Social contributions, ATP and other employer costs

Denmark does not have large employer social security contributions like some other countries, but there are several mandatory and typical employer-paid contributions you must budget for when hiring staff.

The most important are:

• ATP (Arbejdsmarkedets Tillægspension): A statutory labour market supplementary pension. For full-time employees (37 hours per week), the total ATP contribution per month is a fixed amount, of which the employer pays the majority and the employee pays a smaller part via salary deduction. For part-time employees, ATP is reduced according to hours worked.
• AES (Arbejdsskadesikring): Mandatory industrial injury insurance, paid as an annual premium to Arbejdsmarkedets Erhvervssikring via your workers’ compensation insurance provider.
• Barselsfond (maternity/paternity fund): Contributions to a maternity/paternity fund, often through a sector-specific scheme or a general scheme, to help cover costs when employees are on parental leave.

In addition, many employers pay into occupational pension schemes and health insurance as part of the employment package, especially where a collective agreement applies. While not always legally mandatory, they may be required under a collective agreement or expected in your industry.

Employment contracts and working time rules

When you hire an employee, you must provide a written employment contract or employment terms if the employee works a minimum number of hours or the employment lasts beyond a short period. The contract should clearly state:

• Job title and tasks
• Working hours and place of work
• Salary, bonuses and benefits
• Holiday rights and holiday pay rules
• Notice periods and termination conditions
• Any collective agreement that applies

You must also comply with rules on working time, rest periods and overtime. In general, average weekly working hours must not exceed 48 hours over a reference period, and employees are entitled to daily and weekly rest periods.

Mandatory insurance when you have employees

Once you hire staff, certain insurances become mandatory or strongly recommended in Denmark.

Mandatory or typically required insurances include:

• Workers’ compensation insurance (arbejdsskadeforsikring): Legally required for all employees. It covers occupational injuries and diseases and is linked to AES contributions.
• Occupational injury insurance for accidents: Often combined with workers’ compensation in one policy, covering accidents at work.

In addition, many sole proprietors choose to take out:

• Employer’s liability insurance to cover claims from employees for injuries not covered by workers’ compensation
• Business liability insurance if employees work at customer sites or handle customer property
• Professional indemnity insurance if employees provide professional advice or services that could cause financial loss to clients

Insurance premiums depend on your industry, risk level and number of employees. It is advisable to discuss your specific activities with a Danish insurance broker to ensure that you meet legal requirements and have adequate protection.

Using payroll systems and external providers

Handling payroll, holiday pay, ATP, reporting to eIndkomst and insurance can be complex, even for small sole proprietors. To reduce the risk of errors, many business owners use:

• Online payroll systems integrated with eIndkomst and pension providers
• External accountants or payroll bureaus to manage salary calculations and reporting

While this adds a cost, it often saves time and helps you stay compliant with Danish employment and tax rules, allowing you to focus on running and growing your business.

Budgeting for the total cost of an employee

When deciding whether you can afford to hire, remember that the employee’s gross salary is only part of your total cost. You should also factor in:

• Employer share of ATP and other statutory contributions
• Holiday pay and holiday supplement
• Contributions to maternity/paternity funds
• Insurance premiums (workers’ compensation and other policies)
• Any occupational pension contributions and benefits agreed in the contract or collective agreement

Creating a detailed cost calculation before hiring your first employee helps you set the right prices for your services and avoid liquidity problems later.

Using Freelancers and Subcontractors: Contracts and Compliance

Many sole proprietors in Denmark rely on freelancers and subcontractors to stay flexible and keep fixed costs low. However, Danish rules on contracts, tax and labour law are strict, and misclassifying a worker can lead to back taxes, social contributions and fines. Understanding when a person is truly self-employed and how to document the relationship is essential.

Freelancer vs employee under Danish rules

Danish authorities look at the actual working relationship, not the label in the contract. A person is more likely to be considered an employee if several of the following apply:

• They work mainly for one client (you) and are economically dependent on that income
• You decide working hours, place of work and how the work must be performed
• You provide tools, equipment, software licences or a company email address
• They are integrated into your business (e.g. appear as staff on your website, use your internal systems like employees)
• They cannot freely send a substitute to do the work
• You pay a fixed monthly fee or hourly wage on a regular basis, similar to a salary

If most of these factors are present, the Danish Tax Agency (Skattestyrelsen) may reclassify the relationship as employment. In that case, you can be held liable for unpaid A-tax (withholding tax), AM-bidrag (8% labour market contribution), holiday pay and possibly social contributions.

Key elements of a freelancer or subcontractor contract

A written contract is not legally mandatory, but in practice it is crucial for risk management and for demonstrating that the other party is genuinely self-employed. A robust contract for a freelancer or subcontractor in Denmark should typically cover:

• Parties and status – full legal names, CVR/CPR numbers where relevant, and a clear statement that the provider is an independent contractor, not an employee
• Scope of work – detailed description of services, deliverables, deadlines and quality standards
• Price and payment terms – hourly rate or fixed fee, currency (usually DKK), payment deadlines (commonly 8–30 days), late payment interest and invoicing requirements (including VAT if applicable)
• Intellectual property – who owns copyright and other IP rights in the work produced; often the client obtains full rights upon payment
• Confidentiality – obligations to protect business secrets and customer data, including GDPR-related duties
• Liability and insurance – limitations of liability and confirmation that the freelancer holds any required professional or liability insurance
• Subcontracting and substitution – whether the freelancer may use assistants or substitutes and under what conditions
• Term and termination – duration of the agreement, notice periods, and rights to terminate for breach or delay
• Non-solicitation or non-competition – if relevant, reasonable and compliant with Danish competition and labour law
• Applicable law and venue – typically Danish law and Danish courts or arbitration

The contract should be signed before work starts and stored together with related correspondence, offers and purchase orders as part of your accounting documentation.

Tax and VAT responsibilities when using freelancers

As a sole proprietor, you generally do not withhold A-tax or AM-bidrag for a genuine freelancer or subcontractor. They are responsible for their own tax and social contributions. However, you must pay attention to:

• Invoice requirements – Danish freelancers with a CVR number must issue invoices that comply with bookkeeping rules, including name, address, CVR, invoice number, date, description of services, price and VAT where applicable
• VAT (moms) – if the freelancer is VAT-registered, you pay the invoice including VAT and can usually deduct the VAT as input VAT (if the cost relates to your VATable business). If the freelancer is not VAT-registered because their annual turnover is below DKK 50,000, they must not charge VAT
• Reverse charge for foreign freelancers – if you buy services from a freelancer established in another EU country and they invoice without Danish VAT, you may need to apply the reverse charge mechanism and report Danish VAT on the purchase
• Documentation – keep contracts, invoices and proof of payment for at least 5 years in line with Danish bookkeeping rules

If the Danish Tax Agency later decides that a “freelancer” was in fact an employee, you may be required to pay the missing A-tax and AM-bidrag plus interest and possible penalties. Proper contracts, invoices and a clear separation of roles help reduce this risk.

Labour law and working environment considerations

Freelancers and subcontractors are generally not covered by the same protective rules as employees under Danish employment law. However, some obligations still apply to you as the client:

• Work environment – if the freelancer works at your premises or on your sites, you must comply with Danish health and safety rules (Arbejdstilsynet), including risk assessments and safe working conditions
• Collective agreements – if you operate in a sector with strong collective agreements, using freelancers to circumvent minimum pay or working time rules can be challenged by trade unions
• Equal treatment and discrimination – you must avoid discriminatory practices, for example when selecting or terminating collaborations

For long-term or high-volume collaborations, it is often safer to consider an employment contract instead of a freelance arrangement, especially if you control working hours and methods closely.

GDPR and confidentiality when outsourcing work

If freelancers or subcontractors handle personal data on your behalf (for example customer lists, payroll data or online shop orders), you are usually the data controller under GDPR, and the freelancer acts as a data processor. In that case you must:

• Sign a written data processing agreement that meets GDPR requirements
• Ensure the freelancer implements appropriate technical and organisational security measures
• Limit access to personal data to what is necessary for the task
• Ensure data is deleted or returned when the assignment ends

For freelancers outside the EU/EEA, you must also ensure a valid legal basis for international data transfers, such as the EU Standard Contractual Clauses.

Using foreign freelancers and cross-border compliance

When you work with freelancers or subcontractors based abroad, additional rules may apply:

• VAT and reverse charge – services from EU-based freelancers are often subject to the reverse charge mechanism in Denmark; you report Danish VAT on the purchase and may deduct it if the cost is VAT-deductible
• Withholding tax – in some cases (for example certain types of artistic or entertainment services performed in Denmark), Danish withholding tax may apply to payments to foreign individuals
• Permanent establishment risk – if you use subcontractors abroad on a continuous basis, you should assess whether you risk creating a taxable permanent establishment in another country

For cross-border arrangements, it is advisable to obtain tailored advice to avoid unexpected tax or social security liabilities.

Practical tips to stay compliant

To minimise risk when using freelancers and subcontractors as a sole proprietor in Denmark, you can:

• Use written contracts that clearly define the independent status and responsibilities of each party
• Ensure freelancers issue proper invoices and keep all documentation in your accounting records
• Avoid treating long-term freelancers like employees in practice (fixed hours, close supervision, company email, mandatory meetings)
• Check that freelancers have a valid CVR number and, where relevant, the correct licences or professional authorisations
• Review your arrangements regularly with a Danish accountant or legal adviser, especially if the scope or duration of the collaboration changes

Handled correctly, freelancers and subcontractors can be a flexible and tax-efficient way to grow your sole proprietorship in Denmark without taking on the full obligations of an employer.

Banking for Sole Proprietors: Business Accounts and Payment Solutions

Choosing the right banking setup is a practical step when starting a sole proprietorship in Denmark. While you are not legally required to open a separate business bank account as a sole trader, in practice it is strongly recommended. A dedicated account makes it easier to separate private and business finances, meet bookkeeping obligations and prepare your annual tax return.

Do you need a business bank account as a sole proprietor?

From a legal perspective, a sole proprietorship is not a separate legal entity from you as a person. This means you can technically use your private account for business income and expenses. However, most accountants and the Danish Tax Agency (Skattestyrelsen) recommend a separate account because it:

• simplifies bookkeeping and VAT reporting
• reduces the risk of mixing private and business transactions
• makes it easier to document income and costs during a tax audit
• improves your professional image towards customers and suppliers

Many banks also require you to open a business account once they see regular business-related transactions on a private account.

How to open a business account in Denmark

Danish banks are obliged to follow strict anti–money laundering rules. As a result, opening a business account can take time and you should be prepared to provide detailed documentation. Typical requirements for a sole proprietorship include:

• your CPR number and valid ID (passport or national ID card)
• your Danish address and contact details
• CVR number of your sole proprietorship (if registered with the Danish Business Authority)
• a short description of your business model, services or products
• information about expected annual turnover and main customer groups
• links to your website, social media or contracts, if available

Some banks may ask for a business plan, previous accounts (if you have operated before) or proof of funds. If you are a foreign resident or have recently moved to Denmark, expect additional questions and possibly a longer processing time.

Costs and typical fees

Business banking is usually more expensive than private banking in Denmark. Fees vary by bank and package, but you should expect:

• a monthly account fee, often in the range of DKK 50–200 per account
• fees for international transfers and currency exchange
• card fees for a business debit or credit card
• separate fees for acquiring card payments (Dankort, Visa, Mastercard) through a payment service provider

Some banks offer special packages for small businesses and start-ups with reduced fees for the first year. It is worth comparing offers from several banks and checking whether they integrate with your accounting software.

Using your NemKonto as a sole proprietor

Every person with a CPR number in Denmark must have a NemKonto, which is the bank account used by public authorities to pay out tax refunds, benefits and other public payments. As a sole proprietor, you can:

• keep your personal NemKonto for private payments from authorities
• register a separate NemKonto for your business under your CVR number

Having a dedicated business NemKonto makes it easier to keep track of VAT refunds and other business-related payments from the state. You can change or register your NemKonto online via your bank or NemKonto’s self-service, using MitID.

Payment solutions for Danish sole proprietors

Customers in Denmark expect modern and convenient payment options. The right mix depends on whether you sell online, in a physical location or provide services at the customer’s site.

Bank transfers and invoices

Bank transfers are widely used for B2B and many B2C services. You can include your account number and registration number on invoices and ask customers to pay by transfer. For recurring invoices or subscriptions, many accounting systems integrate with payment services that automate reminders and reconciliation.

MobilePay for business

MobilePay is one of the most popular payment methods in Denmark. As a sole proprietor, you can apply for a MobilePay Business solution, which allows customers to pay via their smartphone using a business number or QR code. Key points include:

• you must have a Danish bank account to receive MobilePay settlements
• you pay a fixed monthly fee and/or a fee per transaction, depending on the agreement
• payments are typically settled to your bank account daily

MobilePay is particularly useful for small shops, cafés, freelancers, tradespeople and anyone who needs a simple way to accept in-person payments without a traditional card terminal.

Card terminals and in-person card payments

If you run a physical shop or regularly meet customers face to face, you may need a card terminal. In Denmark, card payments typically involve three elements:

• a terminal provider (for example Nets or other payment service providers)
• a card acquiring agreement for Dankort and international cards
• your business bank account, where settlements are paid

Costs usually consist of a monthly rental fee for the terminal, transaction fees per payment and sometimes a setup fee. Many modern terminals are mobile and work via 4G or Wi-Fi, which is useful for tradespeople and service providers on the move.

Online payments and e-commerce

If you sell online, you will need an online payment solution that can handle cards and possibly other methods such as MobilePay Online. Common options include:

• payment gateways that integrate with Danish and international cards
• all-in-one providers that combine gateway, acquiring and sometimes invoicing
• platform-specific solutions built into webshop systems

When choosing a provider, compare:

• transaction fees and monthly costs
• support for Danish payment habits (Dankort, MobilePay, international cards)
• integration with your webshop and accounting software
• settlement times to your bank account

International payments and multi-currency accounts

If you work with foreign customers or suppliers, you may receive or send payments in EUR or other currencies. Danish banks typically offer:

• international transfers via SEPA (for EUR in the EU/EEA) and SWIFT
• foreign currency accounts (for example EUR or USD accounts)

International transfers usually involve higher fees and currency exchange costs. Some sole proprietors use specialised fintech services for cheaper cross-border payments, but you should ensure that any provider you use is properly licensed and compatible with your bookkeeping and tax reporting.

Security, compliance and documentation

As a business owner, you are responsible for keeping your banking access secure and complying with Danish and EU regulations. In practice this means:

• using MitID and strong authentication for online banking
• restricting access to your accounts if you use bookkeepers or employees
• keeping invoices, receipts and bank statements for at least 5 years, as required by Danish bookkeeping rules
• being prepared to explain unusual or large transactions to your bank due to anti–money laundering rules

Well-organised banking and payment solutions make it easier to meet your tax and VAT obligations, reduce administrative work and present a professional image to your customers.

Insurance Needs for Sole Proprietors (Liability, Accident, Professional Indemnity)

Choosing the right insurance is a key part of risk management for sole proprietors in Denmark. Even though you run the business in your own name and many insurances are not legally mandatory, a single claim, accident or data breach can easily exceed your annual profit. Below you will find the main types of insurance that Danish sole traders typically need, how they work and when they may be required by law or by contract.

Public liability insurance (erhvervsansvarsforsikring)

Public liability insurance covers compensation claims if your business causes personal injury or property damage to third parties in the course of your work. For many trades and service businesses in Denmark, this is the most important basic cover.

Typical situations where liability insurance is relevant include:

• Damaging a client’s property while working on-site (for example, a carpenter damaging floors or a cleaner damaging furniture)
• A customer or visitor slipping and getting injured at your office, workshop or shop
• Causing damage when installing, repairing or delivering goods at a customer’s premises

Liability insurance normally covers legal costs, court fees and compensation up to an agreed sum insured. Common coverage limits for small sole proprietors start around DKK 2–5 million per claim, but higher limits are often recommended for construction, installation and advisory work. Many business customers, municipalities and large companies require proof of liability insurance and may specify a minimum coverage (for example DKK 5–10 million) in their contracts or tenders.

Product liability insurance

If you manufacture, import or sell physical products under your own name, you can be held liable under Danish and EU product liability rules if a defective product causes injury or damage. Product liability insurance is usually an add-on to public liability insurance and is particularly relevant if you:

• Produce or assemble goods or components
• Import products from outside the EU/EEA and sell them in Denmark or the EU
• Sell products under your own brand label

Coverage limits should reflect the potential damage a defective product can cause, especially if you sell to consumers or to other businesses that use your products in their own production.

Professional indemnity insurance (erhvervs- eller rådgiveransvar)

Professional indemnity insurance protects you if a client claims financial loss due to errors, negligence or omissions in your professional advice or services. This type of cover is particularly relevant for knowledge-based and advisory businesses, such as:

• Accountants and bookkeepers
• Tax and legal advisers (where separate, stricter rules may apply)
• IT consultants, software developers and web agencies
• Architects, engineers and designers
• Marketing, HR and management consultants

Professional indemnity typically covers:

• Claims for pure financial loss (for example, a client losing money due to incorrect advice or a faulty IT solution)
• Legal defence costs and settlements
• Claims arising from unintentional breaches of contract or professional standards

For some regulated professions in Denmark, professional indemnity insurance is effectively mandatory because it is required by law, by professional bodies or by client contracts. Even when not legally required, many corporate clients will not sign a contract unless you can document adequate professional indemnity coverage. Coverage limits for small advisory businesses often start at DKK 1–2 million per claim, but higher limits may be needed if you handle large projects or high-value transactions.

Occupational accident insurance (arbejdsskadeforsikring)

If you hire employees, Danish law requires you to take out occupational accident insurance for them. This insurance covers work-related injuries and occupational diseases and must be in place from the first day an employee starts working for you.

As a sole proprietor without employees, you are not automatically covered by the statutory workers’ compensation scheme. You can, however, buy voluntary occupational accident insurance or similar personal accident cover for yourself. This is strongly recommended if you:

• Perform physical work (construction, transport, cleaning, crafts, installation)
• Work with machinery, tools or hazardous materials
• Drive extensively for business purposes

Accident insurance can provide lump-sum payments or ongoing compensation in case of permanent injury, loss of earning capacity or death, and may also cover treatment costs and rehabilitation.

Business property and contents insurance

Business property insurance covers your business assets against risks such as fire, theft, vandalism and water damage. As a sole proprietor, your private home insurance usually does not cover business equipment or stock unless you have explicitly agreed this with your insurer.

Consider business property or contents insurance if you have:

• Computers, servers, tools, machines or specialised equipment
• Inventory or goods stored at home, in a workshop, office or warehouse
• A physical shop, clinic, studio or office with furniture and fittings

Make sure to declare correctly whether you run the business from home or from separate premises, and keep your sum insured up to date as you buy new equipment or increase your stock.

Business interruption insurance

Business interruption insurance can compensate you for lost profit and fixed costs if your business cannot operate due to a covered event such as fire, water damage or other insured property damage. This can be important if you have:

• Significant fixed costs (rent, leases, subscriptions, loan repayments)
• Dependence on specific premises, equipment or machinery to generate income
• Long-term projects where delays can trigger contractual penalties

For sole proprietors, business interruption insurance can help you cover ongoing expenses and protect your personal finances while you rebuild or relocate your business after a major incident.

Cyber and data protection insurance

Even very small Danish businesses are subject to the GDPR and can be liable for data breaches, hacking incidents or accidental disclosure of personal data. Cyber insurance can help cover the costs of:

• IT forensics and recovery after hacking, ransomware or data loss
• Notifying affected individuals and authorities under GDPR rules
• Legal assistance and potential compensation or fines related to data breaches

Cyber cover is particularly relevant if you store customer data, process online payments, run a web shop, provide IT services or rely heavily on cloud systems and email. Some insurers offer combined packages for small businesses that include basic cyber and data protection coverage.

Car and transport insurance for business use

If you use a car, van or other vehicle for your sole proprietorship, you must have at least the mandatory third-party liability insurance required under Danish law. If the vehicle is registered as a business vehicle, or if you use a private car extensively for business purposes, you should inform your insurer and ensure that your policy covers commercial use.

Depending on your risk profile, you may also want:

• Comprehensive (kasko) insurance for damage to your own vehicle
• Goods-in-transit insurance for tools, equipment or goods you transport
• Roadside assistance, especially if you depend on the vehicle to serve clients

Legal expenses insurance

Legal expenses insurance (retshjælpsforsikring) can help cover legal costs in case of disputes related to your business, such as disagreements with customers, suppliers, landlords or other parties. For sole proprietors, legal expenses cover is often included as an add-on to liability or property insurance, or as part of a broader business insurance package.

This type of insurance can be particularly useful if you sign long-term contracts, lease premises, or operate in sectors where disputes are relatively common.

Income protection and health-related cover

As a sole proprietor, your personal income depends directly on your ability to work. In addition to statutory social security and any voluntary unemployment insurance (A-kasse), you may consider:

• Private health insurance to access faster treatment and reduce downtime
• Critical illness insurance that pays a lump sum if you are diagnosed with certain serious diseases
• Income protection or disability insurance that provides ongoing payments if you lose your earning capacity due to illness or accident

These insurances are not specific to sole proprietors but are often more important when you do not have the safety net of an employer.

Contractual and sector-specific insurance requirements

In Denmark, some industries and public-sector clients impose specific insurance requirements on suppliers and subcontractors. Examples include:

• Minimum liability coverage for construction, installation and technical services
• Professional indemnity insurance for advisory and consulting work
• Special environmental or pollution liability in certain sectors

Always read tender documents and contracts carefully and make sure your policies meet the stated minimum sums insured, geographical scope (for example, coverage within the EU/EEA) and any special clauses such as retroactive cover or extended reporting periods for claims.

How to choose and review your insurance as a sole proprietor

When setting up or expanding your sole proprietorship in Denmark, it is advisable to:

1. Map your main risks: physical work, advisory work, data handling, premises, vehicles and employees.
2. Decide which risks you can handle yourself and which must be transferred to insurance.
3. Obtain offers from several Danish insurers or brokers and compare coverage limits, exclusions, deductibles and premiums.
4. Check whether your private insurances (home, contents, car, health) can or cannot be extended to cover business activities.
5. Review your insurance annually or when your turnover, staff, premises or services change significantly.

Well-structured insurance coverage will not only protect your personal finances but can also make your business more attractive to clients, banks and partners, and help you comply with legal and contractual obligations in Denmark.

Data Protection (GDPR) Responsibilities for Small Business Owners

Running a sole proprietorship in Denmark almost always involves processing personal data about customers, employees, suppliers or website visitors. This means you are a data controller under the EU General Data Protection Regulation (GDPR) and the Danish Data Protection Act, even if your business is very small or part-time. Compliance is not optional and the Danish Data Protection Agency (Datatilsynet) can impose investigations, corrective measures and administrative fines for serious breaches.

When GDPR applies to your sole proprietorship

GDPR applies whenever you collect, store or use information that can identify a living person. Typical examples for Danish sole traders include:

• Customer details such as names, addresses, phone numbers, email addresses and payment information
• Employee data such as CPR numbers, salary information, bank accounts, holiday and sickness records
• Supplier contact details and contact persons at business partners
• Website analytics, cookies, IP addresses and newsletter subscription lists

GDPR does not apply to purely personal or household activities, but almost all commercial activities fall within its scope, regardless of your turnover or number of employees.

Key principles you must follow

As a data controller in Denmark, you must be able to demonstrate that you follow the core GDPR principles:

• Lawfulness, fairness and transparency – you must have a legal basis for processing (for example contract, legal obligation, legitimate interest or consent) and clearly inform people how you use their data.
• Purpose limitation – collect data only for specific, explicit and legitimate purposes and do not use it for incompatible purposes later.
• Data minimisation – only collect the data you actually need. For example, do not request a CPR number if an email address is sufficient.
• Accuracy – keep personal data up to date and correct or delete inaccurate information.
• Storage limitation – keep data in identifiable form only as long as necessary for your purposes and legal retention obligations.
• Integrity and confidentiality – protect data against unauthorised access, loss or damage using appropriate technical and organisational measures.
• Accountability – you must be able to document that you comply, for example through written procedures and records.

Legal bases commonly used by small businesses

You must identify a legal basis for each type of processing. For Danish sole proprietors, the most common are:

• Contract – processing necessary to enter into or perform a contract with a customer, supplier or employee (for example issuing invoices, delivering services, paying salaries).
• Legal obligation – processing required by Danish law, such as bookkeeping rules, tax and VAT reporting to Skattestyrelsen or employment law obligations.
• Legitimate interest – processing necessary for your business interests, provided these are not overridden by the interests or rights of the individual (for example basic customer administration, limited direct marketing to existing customers).
• Consent – freely given, specific, informed and unambiguous permission, used especially for email marketing to non-customers and certain types of cookies.

Consent must be as easy to withdraw as it is to give. Pre-ticked boxes or bundled consents are not valid under GDPR and Danish guidance.

Information duties and privacy policy

You must clearly inform individuals about how you process their personal data. In practice, this usually means having a written privacy policy available on your website and in relevant offline contexts. The information must cover at least:

• Who you are (business name, CVR number, contact details)
• What categories of personal data you collect and for what purposes
• The legal basis for each processing activity
• How long you store the data or the criteria used to determine retention periods
• Who you share data with, including data processors and public authorities
• Whether data is transferred outside the EU/EEA and on what legal basis
• The rights of data subjects and how they can exercise them
• The right to complain to the Danish Data Protection Agency (Datatilsynet)

The information must be written in clear and plain language, not legal jargon, and must be easily accessible before or at the time you collect the data.

Handling data subject rights

Individuals whose data you process have specific rights under GDPR. As a sole proprietor, you must have simple procedures to handle:

• Right of access – people can request a copy of the personal data you hold about them and information about how it is used. You normally must respond without undue delay and at the latest within one month.
• Right to rectification – you must correct inaccurate or incomplete data.
• Right to erasure – in certain situations, people can ask you to delete their data, for example when it is no longer necessary for the original purpose and no legal obligation requires you to keep it.
• Right to restriction and objection – individuals can in some cases limit how you use their data or object to processing based on legitimate interests or direct marketing.
• Right to data portability – for data processed by automated means based on consent or contract, individuals can request a copy in a commonly used, machine-readable format.

You must verify the identity of the requester and document how you handle requests. If you refuse a request, you must explain why and inform the person about their right to complain to Datatilsynet.

Data processors and cloud services

Many small businesses in Denmark use external providers for accounting software, CRM systems, email marketing tools, cloud storage or payroll. When these providers process personal data on your behalf, they are data processors, and you remain responsible as the controller.

You must:

• Choose processors that provide sufficient guarantees of GDPR compliance and security
• Sign a written data processing agreement (DPA) that meets GDPR and Danish requirements
• Ensure the processor only acts on your documented instructions and does not use the data for its own purposes
• Know where the data is stored and whether it is transferred outside the EU/EEA

If data is transferred to countries outside the EU/EEA, you must ensure a valid transfer mechanism, such as an adequacy decision from the European Commission or standard contractual clauses, and assess whether additional safeguards are needed.

Security measures appropriate for small businesses

GDPR requires “appropriate” technical and organisational security measures. For a Danish sole proprietorship, this typically includes:

• Using strong, unique passwords and multi-factor authentication for email, accounting systems and cloud services
• Encrypting laptops, smartphones and external drives that store personal data
• Regularly updating software and using reputable antivirus and firewall solutions
• Limiting access to personal data to what is strictly necessary, even if you are the only person in the business
• Backing up important data securely and testing restoration
• Locking physical files in cabinets and controlling access to your office or home office

You should document your security measures in a short internal policy and review them regularly, especially when you introduce new systems or services.

Data breaches and notification duties

A personal data breach is any security incident that leads to accidental or unlawful destruction, loss, alteration, unauthorised disclosure of or access to personal data. Examples include sending an email with personal data to the wrong recipient, losing an unencrypted laptop or being affected by ransomware.

As a data controller in Denmark, you must:

• Keep an internal log of all personal data breaches, even minor ones
• Assess the risk to the rights and freedoms of affected individuals
• Notify Datatilsynet without undue delay and in principle within 72 hours if the breach is likely to result in a risk to individuals
• Inform affected individuals without undue delay if the breach is likely to result in a high risk, for example identity theft or financial loss

Having a simple incident response plan helps you act quickly and consistently if something goes wrong.

Cookies, tracking and online marketing

If you operate a website or online shop in Denmark, you must comply with both GDPR and the Danish rules on cookies and electronic communications. In practice, this means:

• Obtaining valid consent for non-essential cookies and similar tracking technologies, such as marketing and statistics cookies that are not strictly necessary for the service
• Providing a clear cookie banner and a detailed cookie policy describing the types of cookies used, their purposes, duration and third-party providers
• Allowing users to accept or reject different categories of cookies and to change their preferences later
• Ensuring that consent is granular, informed and not bundled with other terms

For email and SMS marketing, you must respect Danish marketing rules and GDPR. In general, you need prior consent from recipients unless you meet the strict conditions for marketing to existing customers, and you must always offer an easy opt-out.

Special categories of data and CPR numbers

Special categories of personal data (such as health information, trade union membership, religious beliefs or biometric data) are subject to stricter rules. Most sole proprietors should avoid collecting such data unless it is absolutely necessary and clearly covered by a legal basis and an exception under GDPR and Danish law.

CPR numbers are also subject to specific Danish rules. You may only process CPR numbers when:

• It is required by law (for example for tax, salary or reporting obligations)
• It is clearly justified by the purpose and necessary for secure identification
• You have obtained explicit consent that meets Danish requirements

CPR numbers must be protected with particularly strong security measures and should never be sent unencrypted by email.

Record-keeping and documentation

Even as a small business, you are expected to document your GDPR compliance. In practice, this often includes:

• A simple register of your processing activities (what data you process, for what purpose, on what legal basis, where it is stored, who it is shared with and how long it is kept)
• Copies of data processing agreements with your IT, cloud, payroll and marketing providers
• Internal procedures for handling data subject rights, data breaches and security updates
• Evidence of cookie and marketing consent mechanisms

Keeping this documentation up to date will make it easier to demonstrate compliance if Datatilsynet contacts you and will help you manage risks as your business grows.

Practical steps to stay compliant

For most Danish sole proprietors, GDPR compliance can be managed with a structured but pragmatic approach. Useful steps include:

• Mapping what personal data you collect, where it comes from and who you share it with
• Deleting data you no longer need and setting clear retention periods for the rest
• Updating your privacy policy, cookie policy and website consent tools
• Reviewing contracts with IT and cloud providers and signing compliant data processing agreements
• Implementing basic security measures and backup routines
• Training any employees or regular freelancers on how to handle personal data securely

By integrating data protection into your daily routines, you reduce legal risk, build trust with customers and create a more robust foundation for your business in Denmark.

Cross-Border Activities: Selling to EU and Non-EU Customers as a Sole Trader

Selling goods or services across borders as a Danish sole proprietor opens up new markets, but it also brings extra VAT, customs and invoicing rules. The exact treatment depends on whether your customers are in the EU or outside the EU, and whether they are private consumers (B2C) or businesses (B2B).

Selling to EU customers (goods)

If you sell physical goods to customers in other EU countries, you must distinguish between sales to businesses and to private consumers.

For B2B sales to VAT-registered customers in another EU country, the supply is usually zero-rated in Denmark. You do not charge Danish VAT if:

• your customer has a valid EU VAT number, and
• the goods are transported from Denmark to another EU country.

You must state both your Danish VAT number and the customer’s VAT number on the invoice and report the sale in the EU sales list (EU-salg uden moms / EC Sales List). The customer accounts for VAT in their own country under the reverse charge mechanism.

For B2C sales of goods to private consumers in other EU countries, the EU “distance selling” rules apply. Denmark participates in the One Stop Shop (OSS) scheme for cross-border B2C sales within the EU. If your total annual cross-border B2C sales of goods and certain services to all EU countries together exceed EUR 10,000 (excluding VAT), you must charge VAT based on the customer’s country and either:

• register for OSS in Denmark and declare foreign VAT via the OSS return, or
• register directly for VAT in each EU country where you have customers.

Below the EUR 10,000 threshold, you can normally continue to charge Danish VAT, but many businesses still choose OSS registration early to avoid monitoring the threshold and to prepare for growth.

Selling to EU customers (services)

For B2B services to VAT-registered customers in other EU countries, the general rule is that the place of supply is where the customer is established. You usually do not charge Danish VAT and instead apply the reverse charge, provided you:

• verify and record the customer’s valid EU VAT number, and
• state “reverse charge” (or an equivalent reference) on the invoice.

These B2B services must also be reported in the EU sales list when they fall under the general B2B rule.

For B2C services to private individuals in other EU countries, the rules depend on the type of service. For many digital services (for example, apps, streaming, downloadable software, online courses without live interaction), VAT is due in the customer’s country. If your total cross-border B2C digital sales in the EU exceed EUR 10,000 per year, you must charge VAT at the customer’s rate and can use the OSS scheme to report and pay it.

Selling to non-EU customers (exports)

When you sell goods to customers outside the EU, the supply is usually treated as an export and is zero-rated for Danish VAT, provided the goods are physically transported out of the EU and you keep proper export documentation (for example, customs export declaration, transport documents). You still need to record the sale in your bookkeeping and keep evidence that the goods left the EU.

For services supplied to non-EU business customers, many services are outside the scope of Danish VAT because the place of supply is where the customer is established. In those cases, you do not charge Danish VAT, but you should clearly indicate on the invoice that the service is not subject to Danish VAT and keep documentation of the customer’s status and location.

For B2C services to private consumers outside the EU, some services are taxed in Denmark and others where the customer is located. The rules are particularly specific for digital services, telecoms, broadcasting and certain advisory services. You should check the exact rules for your type of service before you start selling to non-EU consumers.

Import VAT and customs when buying from abroad

Cross-border activity also affects your purchases. When you buy goods from suppliers in other EU countries, they often invoice you without VAT if you provide your Danish VAT number. You must then account for Danish VAT on the purchase (acquisition VAT) in your VAT return and can usually deduct it as input VAT if the goods are used for VATable business activities.

For imports of goods from non-EU countries, Danish import VAT and possibly customs duties apply. Import VAT is normally calculated on the customs value plus any customs duty and certain costs. As a VAT-registered sole proprietor, you usually declare and deduct import VAT via your VAT return, but you must ensure that your EORI number and VAT number are correctly used in customs declarations.

Invoicing, documentation and VAT registration

For cross-border sales, invoices must contain specific information, including:

• your full name, address and Danish CVR/VAT number
• the customer’s name and address, and for B2B within the EU, their VAT number
• description of goods or services, quantity and delivery date
• price, currency and any discounts
• applied VAT rate and amount, or a clear reference to why no VAT is charged (for example, “reverse charge”, “intra-Community supply”, “export of goods”)

You must keep records of all cross-border transactions, including contracts, invoices, transport documents and proof of export, for the period required under Danish bookkeeping rules. This documentation is essential in case of a VAT audit.

If you expect to sell cross-border from the start, you should consider:

• registering for Danish VAT early, even if your turnover is below the general Danish VAT registration threshold of DKK 50,000 in 12 months
• registering for the EU OSS scheme if you sell B2C to customers in several EU countries
• obtaining an EORI number if you import or export goods to or from non-EU countries

Practical tips for managing cross-border sales

Before you begin selling abroad, review your pricing to include foreign VAT, customs duties, shipping and insurance so that your margins remain sustainable. Make sure your website, terms and conditions and checkout process clearly state which countries you deliver to, who is responsible for customs and import charges, and which VAT will be applied.

Use accounting and e-commerce systems that can handle multiple VAT rates, currencies and country rules. This reduces manual work and the risk of errors in your VAT returns and OSS filings. If you are unsure about the correct VAT treatment for a specific product or service, seek advice before you start selling, as mistakes in cross-border VAT can become costly over time.

Working While Employed: Combining a Sole Proprietorship with a Job in Denmark

Many people in Denmark run a small business on the side while keeping a regular job. This can be an efficient way to test a business idea, build a client base and increase your income without giving up the security of a monthly salary. However, combining employment with a sole proprietorship (enkeltmandsvirksomhed) affects your tax, social security, contracts and work–life balance, so it is important to understand the rules.

Can you run a sole proprietorship while employed?

In Denmark you are generally allowed to be employed and run a sole proprietorship at the same time. There is no requirement to ask the authorities for special permission just because you have both salary income and business income.

The main limitations usually come from your employment contract and any internal policies at your workplace. Before you register your business, you should carefully check:

• Whether your contract includes a non-compete clause that restricts you from running a business in the same industry as your employer
• Any non-solicitation clause that prevents you from taking over or approaching your employer’s customers, suppliers or employees
• Confidentiality clauses that prohibit you from using know-how, methods, software or trade secrets from your job in your own business
• Rules on secondary occupations (bibeskæftigelse), for example a requirement to inform or obtain written consent from your employer

If you breach these clauses, your employer may issue a warning, terminate your employment or in serious cases claim compensation. When in doubt, ask a lawyer or union representative to review your contract.

Working hours, rest periods and conflict of interest

Even though there is no general legal limit on how many hours you can work across all jobs and self-employment, you must still comply with working time and health and safety rules. If you are covered by a collective agreement, it may include specific limits on weekly working hours or rules on overtime that you need to respect.

Your side business must not interfere with your ability to perform your job. In practice this means:

• You should not work on your own business during paid working hours for your employer, unless you have explicit permission
• You must not use your employer’s equipment, software licences, vehicles or materials for your private business unless this is clearly agreed and taxed correctly as a fringe benefit
• You should avoid situations where your personal financial interest in your business conflicts with your employer’s interests, for example when choosing suppliers or recommending services to customers

Public sector employees often face stricter rules on conflicts of interest and side activities. If you work in the public sector, check your institution’s guidelines and, if necessary, obtain written approval before starting your business.

Taxation when you have both salary and business income

In Denmark, all your income is combined when SKAT calculates your tax. Your salary, business profit, certain benefits and investment income are added together and taxed under the same progressive system.

Key points when you are both employed and self-employed:

• Tax card (skattekort): Your main employer normally uses your primary tax card with your personal allowance. Other employers and payers use your secondary tax card. Business income from a sole proprietorship is not paid through a tax card; you pay tax via preliminary tax (B-skat) and the final annual tax assessment.
• Preliminary income assessment (forskudsopgørelse): You must enter your expected annual business profit in your preliminary assessment so that SKAT can calculate your B-tax and AM-bidrag (labour market contribution). Adjust this during the year if your income changes significantly.
• Labour market contribution: Both your salary and your business profit are subject to 8% labour market contribution before income tax is calculated.
• Tax brackets: Because your incomes are added together, your total income may move you into higher tax brackets. In practice, this means that extra income from your business may be taxed at a higher marginal rate than your salary alone.

At year-end you must submit your tax return (årsopgørelse/udvidet selvangivelse) and report your business results. If you use the business schemes (virksomhedsordningen or kapitalafkastordningen), you must follow the specific rules for these, including separate accounts and correct allocation of interest and capital.

Deducting business expenses when you also have a job

Running a sole proprietorship allows you to deduct business-related expenses from your business income, even if you also have a full-time job. Only costs that are directly related to earning business income are deductible.

Typical deductible expenses include:

• Office supplies, software subscriptions and professional tools used for your business
• Marketing costs, such as website hosting, online ads and printed materials
• Professional insurance, accounting and legal fees related to the business
• Business travel and mileage, calculated according to the official Danish mileage rates when you use your private car for business purposes

Private expenses are never deductible. If an expense is partly private and partly business-related, you may only deduct the business portion. This is particularly important when you work from home or use your private phone, internet or car for both employment and business. Keep clear documentation and a reasonable allocation method in case SKAT asks for details.

Unemployment benefits and sickness benefits

If you are a member of an unemployment insurance fund (a-kasse), combining employment with self-employment can affect your right to dagpenge (unemployment benefits) if you lose your job later.

In general, a-kasser distinguish between:

• Full-time self-employment: If your business is considered your main occupation, you may not be entitled to unemployment benefits until you close or suspend the business according to the a-kasse’s rules.
• Secondary self-employment: If your business is clearly a side activity and your main attachment to the labour market is through your job, you may keep your business and still receive benefits if you become unemployed, provided you can take full-time work and your business does not prevent you from accepting job offers.

Each a-kasse has detailed criteria for what counts as a side business, including time spent, turnover and whether you have employees. It is important to inform your a-kasse about your business when you start it and obtain written confirmation of how it will affect your rights.

Regarding sickness benefits (sygedagpenge), your employer normally pays salary during sickness according to your contract or collective agreement. If you are self-employed and your business income is significant, you may also be entitled to sickness benefits as a self-employed person after a waiting period, provided you meet the income and registration requirements. The municipality assesses your entitlement based on your combined situation.

Holiday, parental leave and other employment rights

Your rights to paid holiday, parental leave and other benefits from your employer are not automatically reduced because you run a sole proprietorship. However, you must ensure that your business activities do not prevent you from actually taking leave from your job.

For example, if you are on paid holiday or parental leave from your employer, but you continue to work intensively in your own business, this may raise questions about whether you are genuinely on leave. In some situations, this can affect your right to benefits or compensation. If you plan to work in your business during periods of leave, discuss this with your employer and, if relevant, with Udbetaling Danmark or your a-kasse.

Practical tips for balancing a job and a sole proprietorship

To make the combination of employment and self-employment sustainable, consider the following practices:

• Set clear time boundaries so that your business does not consistently extend your working day to an unhealthy level
• Use separate email addresses, phone numbers and calendars for your job and your business to avoid confusion
• Keep separate bank accounts to distinguish personal, salary and business transactions, even if a dedicated business account is not legally required
• Maintain up-to-date bookkeeping so that you can quickly see whether your side business is profitable and worth your time
• Regularly review your preliminary tax assessment to avoid large back payments at year-end

Combining a job with a sole proprietorship in Denmark can be a strong financial and professional strategy, as long as you respect your contractual obligations, manage your tax correctly and protect your own health and work–life balance.

Closing or Temporarily Suspending a Sole Proprietorship in Denmark

At some point you may decide to pause your activity as a sole proprietor in Denmark or close your business completely. Understanding the formal options, deadlines and tax consequences helps you avoid unexpected bills and penalties.

Closing a sole proprietorship (permanent cessation)

If you stop your business permanently, you must deregister it with the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (Skattestyrelsen). This is done digitally via Virk and TastSelv Erhverv. You should deregister as soon as you know that business activities will end, and no later than when you issue your last invoice.

Key steps when closing:

• Submit deregistration for your CVR number (if you are VAT registered or registered as an employer)
• Deregister for VAT (moms) and, if relevant, payroll taxes (AM-bidrag, A-skat) and A-tax as an employer
• Prepare a final set of accounts up to the closing date
• File your final business tax information in your personal tax return (oplysningsskema) via TastSelv
• Settle outstanding VAT, A-tax, AM-contributions and other duties
• Cancel any business insurances, subscriptions and contracts that are no longer needed

When you close, you must calculate and report VAT on remaining business assets that you keep for private use if their value exceeds the normal thresholds. This can include inventory, equipment and some fixed assets where you previously deducted input VAT. For larger assets such as real estate or expensive equipment, VAT adjustment rules may apply over a period of up to 10 years.

Any business losses that have not yet been used can normally still be offset against your other personal income, subject to the general Danish tax rules on loss carry-forward. You remain personally liable for all business debts, including tax and VAT, even after the business is closed.

Temporarily suspending a sole proprietorship

If you expect to resume activity, you can choose to keep the business registered but inactive, or you can deregister for VAT and as an employer while keeping the CVR number. The right solution depends on how long the inactivity will last and whether you still have ongoing costs or contracts.

Typical options include:

• Keeping the CVR and VAT registration: You may do this if you still have minor activity, such as a few invoices or ongoing contracts. You must continue to submit VAT returns for each period, even if they are zero.
• Deregistering for VAT but keeping the CVR: If you stop all taxable activity and do not expect turnover above the VAT registration threshold (currently 50,000 DKK over a 12‑month period), you can deregister for VAT. You can later re-register for VAT if activity resumes.
• Deregistering as an employer: If you no longer have employees, you must deregister as an employer so you are not required to submit payroll reports (eIndkomst) and A-tax/AM-bidrag filings.

Even during a suspension you must keep proper accounting records, store vouchers and contracts for at least five years, and respond to any inquiries from the tax authorities. If you keep the CVR active, your business information remains visible in the public CVR register.

Tax and VAT obligations at closure or suspension

When you close or significantly reduce activity, the tax authorities will focus on whether all income has been reported and whether VAT has been correctly settled. Important points include:

• Report all outstanding income, including late payments received after the closing date, in the correct tax year
• Ensure that all deductible business expenses are recorded before closure, including depreciation and any final write-downs
• Adjust VAT on assets where you previously deducted input VAT and which you keep for private use or sell without VAT
• Submit final VAT returns and pay any remaining VAT within the normal deadlines for your reporting frequency (monthly, quarterly or half-yearly)

If you have used business schemes such as the business tax scheme (virksomhedsskatteordningen) or capital return scheme (kapitalafkastordningen), you must ensure that these are correctly settled when the business stops. This can affect how much of your profit is taxed as personal income versus capital income and whether any deferred tax is triggered.

Employees, contracts and ongoing obligations

If you employ staff, you must handle termination in accordance with Danish employment law and any collective agreements. This includes notice periods, payment of outstanding salary, holiday pay (feriepenge) and reporting to FerieKonto or a holiday fund if relevant. You must also submit final payroll reports and settle A-tax and AM-contributions.

For suppliers, landlords and other business partners, you should review contracts for notice periods and termination clauses. Make sure to cancel or renegotiate:

• Office or warehouse leases
• Telephone, internet and software subscriptions
• Payment solutions and acquiring agreements
• Insurance policies and service contracts

Remember that as a sole proprietor you are personally liable for all contractual obligations. Closing the business does not automatically end your responsibility for guarantees, long-term leases or loans.

Impact on social security and benefits

Closing or suspending your sole proprietorship can affect your access to unemployment benefits (dagpenge) if you are a member of an unemployment insurance fund (A‑kasse). In many cases, you must document that the business is genuinely closed or inactive before you can be considered available for the labour market as an employee.

This often requires:

• Deregistration from VAT and as an employer
• No ongoing marketing or active search for customers
• No significant business assets kept for commercial use

ATP contributions and private pension schemes linked to your business income may also change when your business stops. You should review your pension contributions and insurance coverage to ensure they still match your new situation.

Reopening or starting a new business later

If you have only suspended activity and kept your CVR number, you can usually restart the business by re-registering for VAT and, if needed, as an employer. If you have fully closed and deregistered the business, you may need to apply for a new CVR number when you start again, especially if there are significant changes in activity or business name.

Before restarting, consider whether a sole proprietorship is still the right structure or whether a limited liability company (ApS) would better protect your personal assets, particularly if you expect higher risk, employees or significant investments.

Because closing or suspending a sole proprietorship in Denmark has direct tax, VAT and legal consequences, many business owners choose to consult a Danish accountant or tax adviser to ensure that all registrations, final accounts and declarations are handled correctly.

Common Mistakes When Registering and Running a Sole Proprietorship

Many sole proprietors in Denmark run into avoidable problems simply because they are not familiar with local rules and deadlines. Below are the most common mistakes we see when registering and operating a sole proprietorship – and how to avoid them.

1. Registering Late or in the Wrong Way

A frequent mistake is starting to issue invoices without registering correctly with the Danish Business Authority (Erhvervsstyrelsen). Even though a sole proprietorship (enkeltmandsvirksomhed) is relatively simple, you must:

• Register the business in the Central Business Register (CVR) before or at the time you start your activity
• Register for VAT (moms) if your expected turnover exceeds DKK 50,000 over a 12‑month period

Some owners wrongly assume that small or “hobby” income does not require registration. If SKAT later considers your activity to be a business, you may face retroactive VAT, tax, and interest.

2. Choosing a Business Name That Conflicts with Danish Rules

Another common issue is picking a business name that is too similar to an existing company or that does not meet Danish naming rules. Mistakes include:

• Using a name already registered in CVR, leading to objections or forced name change
• Using protected words (for example, suggesting you are a limited company when you are not)
• Ignoring trademark rights, which can result in legal disputes

Always check the CVR register and consider trademark searches before you register your business name.

3. Mixing Personal and Business Finances

Because a sole proprietorship is not a separate legal entity, many owners mix personal and business money. This makes bookkeeping, tax reporting and documentation very difficult. Typical problems are:

• Using a personal bank account for all business income and expenses
• Lack of clear documentation for business costs, making deductions harder to defend
• Confusion about which assets belong to the business

Even though it is not legally mandatory to have a separate business account, it is strongly recommended. A dedicated account and payment solution make it easier to prove your income and expenses if SKAT asks for documentation.

4. Poor Bookkeeping and Missing Documentation

Danish law requires you to keep orderly accounts and store documentation for at least five years. Common bookkeeping mistakes include:

• Not issuing proper invoices with required information (e.g. CVR number, VAT details)
• Failing to record cash transactions or small expenses
• Not reconciling bank accounts with accounting records
• Throwing away receipts or keeping them only in paper form without backups

Inadequate bookkeeping can lead to estimated tax assessments, denied deductions and possible fines. Using a simple accounting system that complies with Danish rules helps you stay in control.

5. Misunderstanding VAT Obligations and Deadlines

VAT is one of the areas where sole proprietors most often make mistakes. Typical issues are:

• Not registering for VAT when turnover exceeds DKK 50,000 in 12 months
• Charging VAT on exempt services (for example, certain health or educational services)
• Failing to charge VAT on taxable sales, especially to private customers
• Missing VAT filing and payment deadlines, which depend on your turnover bracket

Many new businesses also incorrectly deduct input VAT on expenses that are partly private, such as mobile phones or cars. You may only deduct the business-related part, and you must be able to document your calculation method.

6. Incorrect Treatment of Business Expenses and Deductions

Sole proprietors often either claim too many or too few deductions. Common mistakes include:

• Deducting purely private expenses as business costs
• Not using standard mileage rates for business driving when it would be advantageous
• Failing to depreciate larger assets (e.g. equipment, computers) correctly over time
• Ignoring home office rules and either over‑ or under‑deducting related costs

Overstating deductions can trigger audits and adjustments, while understating them means you pay more tax than necessary. Understanding which expenses are fully deductible, partially deductible or non‑deductible under Danish tax law is essential.

7. Ignoring Personal Tax Planning and B‑Income

Many sole traders underestimate how their business income affects their personal tax. Frequent errors are:

• Not updating the preliminary income assessment (forskudsopgørelse) to include expected business profit
• Ignoring B‑income rules when receiving income without tax withheld
• Underestimating the tax bill and not setting aside enough funds during the year

This often results in large residual tax (restskat) plus interest and possible surcharges. Adjusting your preliminary tax during the year and making voluntary payments can help avoid unpleasant surprises.

8. Overlooking Social Contributions, ATP and Pension

Sole proprietors sometimes assume that social security and pension are handled automatically as with salaried employment. Typical mistakes include:

• Not paying voluntary pension contributions, even though business income may be your main or only income
• Not understanding when ATP contributions apply (for example, when hiring employees)
• Failing to consider insurance against loss of earning capacity or accident, leaving no safety net

As a sole trader, you are responsible for building your own pension and securing social protection. Ignoring this can create serious long‑term financial risk.

9. Misclassifying Workers: Employees vs. Freelancers

Many sole proprietors try to keep costs flexible by using freelancers or subcontractors. A common mistake is treating someone as self‑employed when, under Danish rules, they should be considered an employee. This can lead to:

• Liability for unpaid holiday pay, social contributions and withholding tax (A‑tax)
• Penalties for incorrect reporting to SKAT and other authorities

Factors such as control, integration into your business, and who bears the financial risk determine whether a person is an employee or a genuine freelancer. Written contracts help, but the actual working relationship is decisive.

10. Ignoring Digital Requirements and Official Communication

Denmark is highly digital, and many obligations are handled online. Common mistakes include:

• Not setting up or regularly checking e‑Boks, where authorities send binding messages
• Misplacing NemID/MitID credentials or not granting proper access to your accountant
• Missing deadlines because important letters from SKAT or Erhvervsstyrelsen were not opened

Failing to respond to digital correspondence can lead to automatic estimates, fines and loss of appeal rights. Make it a routine to check e‑Boks and your tax account regularly.

11. Underestimating Liability and Insurance Needs

Because a sole proprietorship does not limit your personal liability, your private assets can be at risk. Common oversights are:

• Operating without professional liability or product liability insurance where it would be prudent
• Not taking out workers’ compensation insurance when hiring employees, even part‑time
• Ignoring contract clauses that shift significant risk to you as a supplier

One serious claim or accident can threaten both your business and personal finances. Assess your risk profile and discuss appropriate insurance cover with a specialist.

12. Failing to Adjust the Business Structure as You Grow

Many entrepreneurs keep operating as sole proprietors even when the business has grown significantly. Common strategic mistakes include:

• Not considering a company structure (e.g. ApS) when profits and risks increase
• Leaving profits in the business without planning for tax‑efficient withdrawals
• Ignoring succession, sale or exit planning until it is too late

While a sole proprietorship is flexible and simple, it is not always the best long‑term solution. Regularly reviewing your structure with an advisor can help you optimise both tax and risk.

How to Avoid These Mistakes

Most of these issues can be prevented by planning ahead, keeping your records in order and seeking professional advice early. Before you register, prepare a simple checklist covering registration, VAT, bookkeeping, tax, banking, insurance and digital access. Reviewing this at least once a year will help you keep your Danish sole proprietorship compliant, efficient and ready to grow.

Checklist Before Registration: Documents, Decisions and Preparations

Before you register a sole proprietorship (enkeltmandsvirksomhed) in Denmark, it is worth preparing a few key documents and decisions. A short preparation phase will make the online registration with the Danish Business Authority (Erhvervsstyrelsen) faster and reduce the risk of mistakes that can later cause tax or compliance issues.

1. Clarify your business model and activities

Start by defining what you will actually do as a business. You will need to describe this when registering and choosing your industry code (branchekode/NACE code).

• Specify your main services or products and your typical customer (private consumers, other businesses, public sector)
• Decide whether you will operate only in Denmark or also sell to customers in other EU countries or outside the EU
• Consider whether your activity is regulated and may require a licence, authorisation or notification (for example financial services, healthcare, food, transport, construction)

2. Decide on your business name and check availability

You can run your sole proprietorship under your own personal name or under a separate business name. Before registration, decide:

• What name you want to use as your primary business name
• Whether you need one or more secondary names (binavne) for different brands or activities

Check that your chosen name:

• Is not already registered as a company name in the Danish Central Business Register (CVR)
• Does not infringe existing trademarks registered in Denmark or the EU
• Is not misleading (for example suggesting you are a company limited by shares if you are a sole proprietor)

If you plan to build a strong online presence, also check the availability of matching domain names and social media handles before you register.

3. Prepare your personal identification and digital access

Registration is done digitally, so make sure you have:

• A valid Danish CPR number
• MitID for secure login to public self-service solutions
• Access to e-Boks, as authorities will send official letters and decisions there

If you are not a Danish citizen but are resident in Denmark, ensure that your CPR and MitID are fully activated before you start the registration process.

4. Choose your business address and contact details

You must provide a Danish business address. This can be your home address, a rented office, a co-working space or another location where you carry out your activity.

• Confirm that your lease or housing rules allow business use of the address
• Prepare a phone number and email address that you will use for business and for contact with authorities
• Decide whether you want your home address to be publicly visible in the CVR register

5. Decide on VAT registration and expected turnover

In Denmark, you must register for VAT (moms) if your taxable turnover exceeds DKK 50,000 over a 12‑month period. Before registration, estimate:

• Your expected turnover in the first year
• Whether you will reach the DKK 50,000 threshold quickly or only after some time
• Whether your services are VAT liable, VAT exempt or partly exempt

Even if you expect to stay below the threshold, consider voluntary VAT registration if you will have significant VAT on purchases and mainly sell to VAT-registered businesses. This can improve your cash flow by allowing you to deduct input VAT.

6. Plan your tax scheme and preliminary tax (B‑tax)

As a sole proprietor, business profit is taxed as your personal income. Before you start, it is useful to:

• Estimate your expected annual profit (revenue minus deductible expenses)
• Decide whether you will use the standard personal taxation or the Danish Business Tax Scheme (virksomhedsordningen), if you qualify and it suits your situation
• Prepare to set up or adjust your preliminary tax (forskudsopgørelse) with the Danish Tax Agency (Skattestyrelsen) so that you pay B‑tax during the year

Remember that Danish personal income tax is progressive and includes municipal tax, state tax, labour market contribution (AM-bidrag) and, above certain income levels, top tax. A realistic profit estimate helps avoid large back payments later.

7. Consider social security, ATP and pension

As a sole proprietor, you are not automatically covered by the same schemes as employees. Before registering, think about:

• How you will secure your pension savings, for example through private pension schemes or business-related pension contributions
• Whether you want to make voluntary contributions to ATP or other supplementary schemes, if relevant
• How you will handle sickness, maternity/paternity leave and unemployment, including possible membership of an unemployment insurance fund (a‑kasse)

8. Set up basic bookkeeping and banking arrangements

Danish law requires proper bookkeeping and retention of accounting records. Before you start invoicing customers:

• Decide whether you will handle bookkeeping yourself or use an accountant or bookkeeper
• Choose bookkeeping software that supports Danish VAT rules, e‑invoicing and reporting to authorities
• Open a separate bank account for business use, even though it is not always legally required for sole proprietors; this makes it easier to separate private and business finances

Also consider what payment methods you will offer (bank transfer, payment cards, MobilePay, online payment gateways) and what fees and settlement times apply.

9. Check insurance needs and risk exposure

As a sole proprietor, you are personally liable for all business obligations. Before registration, assess your risk and consider:

• Professional liability insurance if you provide advice or specialised services
• General liability insurance covering damage to third parties and their property
• Occupational accident insurance if you plan to hire employees (this is mandatory)
• Business interruption or contents insurance if you depend on equipment, stock or premises

10. Review contracts, terms and data protection

Prepare the basic legal framework for your business before you sign your first contract:

• Draft standard terms and conditions for your services or products, including payment terms, delivery, liability and dispute resolution
• Prepare templates for offers, order confirmations and invoices that meet Danish invoicing requirements
• Identify whether you process personal data and, if so, prepare a simple GDPR compliance setup, including privacy policy and data processing agreements with suppliers

11. Personal and time planning

Finally, consider the practical side of running a sole proprietorship:

• How much time you can realistically dedicate to the business alongside any employment or family obligations
• Whether you have a financial buffer to cover living costs and taxes while the business grows
• Who can support you with specialist tasks such as accounting, legal matters or marketing

Once these documents, decisions and preparations are in place, you will be ready to complete the online registration of your sole proprietorship in Denmark quickly and start operating on a solid legal and financial foundation.
