Maximizing Tax Relief for Research and Development Costs in Denmark for 2026

Introduction to Tax Relief for Research and Development in Denmark

Denmark offers a competitive and predictable framework for tax relief on research and development (R&D) costs, designed to support innovation, high‑tech solutions and productivity growth across all sectors. Companies that invest in qualifying R&D activities can benefit from both enhanced tax deductions and, in many cases, a cash refund of tax losses linked to R&D expenditure. Understanding how these rules work is essential for maximizing the value of your innovation budget in 2026.

Under Danish tax law, R&D expenses that are directly related to the development of new or improved products, services, processes or technologies are generally deductible as operating costs. As a baseline, qualifying R&D costs can be deducted at 100% when calculating taxable income. In addition, Denmark allows an uplift on certain R&D expenses, effectively increasing the deductible amount above the actual cost, subject to statutory limits and documentation requirements. This mechanism reduces the effective tax burden for companies that systematically invest in development projects.

A key feature of the Danish system is the possibility to obtain a cash refund for R&D‑related tax losses. If a company’s R&D deductions create or increase a tax loss in a given income year, it may apply for a refund of the corporate tax value of that loss, up to a capped amount of qualifying R&D costs. The refund is calculated using the standard corporate income tax rate of 22%, which means that every eligible Danish krone spent on R&D within the applicable ceiling can generate an immediate cash benefit instead of a deferred tax asset. This is particularly attractive for start‑ups and growth companies that are not yet profitable.

Tax relief for R&D in Denmark is available to a wide range of entities, including Danish limited liability companies and foreign companies with a permanent establishment in Denmark. The rules are sector‑neutral: manufacturing, life sciences, IT, green technologies, logistics, creative industries and many other fields can qualify, provided that the underlying activities meet the definition of R&D for tax purposes. What matters is the systematic search for new knowledge, the resolution of technological or scientific uncertainties, and the creation of innovative solutions that go beyond routine improvements.

To benefit from these incentives, companies must be able to distinguish R&D projects from ordinary operational work and maintain adequate documentation. This typically includes project descriptions, technical objectives, evidence of uncertainties, time records, and a clear allocation of personnel, subcontracting and material costs to specific R&D activities. Proper documentation is crucial both for calculating the tax relief and for demonstrating eligibility in case of a review by the Danish Tax Agency (Skattestyrelsen).

From a strategic perspective, tax relief for R&D is an integral part of Denmark’s broader innovation and competitiveness policy. The regime is designed to be stable and transparent, allowing companies to plan multi‑year development programs with a clear view of the tax implications. For 2026, the focus remains on encouraging companies to keep their research, development and high‑value functions in Denmark, while attracting international investment in advanced technologies and sustainable solutions.

For businesses, this means that every major development initiative should be reviewed through an R&D tax lens. Mapping projects against the Danish R&D criteria, identifying all eligible cost categories and choosing the optimal combination of deductions and refunds can significantly improve the net cost of innovation. In the following sections, we explain the detailed eligibility criteria, the types of activities that qualify, the main R&D tax credit mechanisms available in Denmark, and the practical steps to apply for tax relief on R&D expenses in 2026.

Eligibility Criteria for Tax Relief on R&D Costs in 2026

To benefit from Danish tax relief on research and development (R&D) costs in 2026, companies must meet a set of clearly defined conditions. The rules are designed to support genuine, systematic innovation while preventing the reclassification of ordinary operating expenses as R&D. Below is an overview of the key eligibility criteria that businesses should understand before planning their R&D activities and tax position.

Who can claim R&D tax relief in Denmark?

R&D tax incentives in Denmark are available to a broad range of businesses, provided they are subject to Danish corporate taxation. In practice, this means that:

There is no minimum turnover or size requirement, but the company must keep proper documentation and be able to demonstrate that the activities meet the R&D definition used by the Danish tax authorities.

Definition of qualifying R&D activities

To qualify for tax relief, activities must be directed at achieving new scientific or technological knowledge or at substantially improving existing products, processes or services. The Danish rules broadly follow the OECD Frascati principles. In practice, qualifying R&D must:

Routine changes, cosmetic updates, standard quality control, and activities that only adapt an existing solution to a specific customer, without genuine technological advancement, generally do not qualify.

Types of costs that can be included

Only certain categories of expenditure are eligible for R&D tax relief. As a rule, costs must be directly connected to qualifying R&D projects and properly documented. Typical eligible costs include:

General overheads, marketing expenses, sales activities, and administrative costs are normally excluded, unless a clearly allocable portion can be demonstrated as directly linked to R&D.

Enhanced deduction and limitation thresholds

Danish tax law allows an enhanced deduction for qualifying R&D expenses. Companies can generally deduct 108% of eligible R&D costs when calculating taxable income. This means that for every DKK 100 of qualifying R&D expenditure, DKK 108 can be deducted for tax purposes.

In addition, certain companies may be entitled to a cash refund of the tax value of negative taxable income attributable to R&D, up to a statutory ceiling. The maximum base for such a refund is DKK 25 million of qualifying R&D costs per income year, corresponding to a capped tax value that can be refunded. Amounts above this threshold can still benefit from the enhanced deduction but not from the cash refund mechanism.

Documentation and substantiation requirements

Eligibility is closely tied to the quality of the company’s documentation. To support a claim for R&D tax relief, businesses should maintain:

The Danish Tax Agency may request this documentation during audits. Insufficient or inconsistent records can lead to partial or full denial of the R&D tax relief claimed.

Territorial scope and collaboration projects

As a main rule, only R&D activities and costs that are taxable in Denmark are eligible. However, Danish companies participating in cross-border R&D projects may still claim relief for the portion of work and expenditure that is recognized in the Danish tax base.

Where R&D is carried out in collaboration with universities, research institutions or other companies, it is important to clearly define:

Only the party that actually incurs and bears the R&D costs, and for whom those costs are not reimbursed, can claim the corresponding tax relief.

Sectoral and state aid considerations

Most sectors can benefit from R&D tax relief, but companies operating in areas subject to specific EU state aid rules, such as financial services or certain energy-related activities, should check whether additional limitations apply. Where R&D projects also receive direct public grants or subsidies, the same costs cannot be double-counted for tax relief purposes; the eligible base must be reduced by the amount of non-repayable public funding.

By ensuring that activities, costs and documentation meet these eligibility criteria, companies operating in Denmark can make full and compliant use of the available tax relief on R&D costs in 2026 and integrate these incentives into their long-term innovation strategy.

Types of Research and Development Activities that Qualify for Tax Relief

Research and development tax relief in Denmark is designed to support companies that systematically work on creating new or improved products, services, technologies or processes. To qualify, activities must be innovative, involve technical or scientific uncertainty, and follow a structured project approach with clear objectives, documentation and measurable outcomes.

In practice, qualifying R&D activities can be grouped into several broad categories. The examples below are illustrative and not exhaustive, but they reflect the types of projects that the Danish Tax Agency typically accepts as eligible when properly documented and linked to the company’s business.

Development of new or significantly improved products

Many companies qualify for tax relief through projects aimed at creating new products or substantially enhancing existing ones. This includes:

Routine product updates, cosmetic changes or adaptations without genuine technical uncertainty generally do not qualify, even if they are time-consuming or costly.

Process and production technology innovation

Tax relief is also available for R&D projects focused on how products or services are created and delivered. Typical qualifying activities include:

Standard implementation of existing, well-documented production technologies without adaptation or experimentation is usually considered routine and does not meet the R&D criteria.

Software and digital innovation

Software development can qualify for R&D tax relief when it goes beyond routine coding and configuration. Eligible activities often include:

By contrast, standard web development, integration of existing systems, configuration of off-the-shelf software, bug fixing and user interface adjustments are typically considered non-qualifying unless they are integral to a broader, uncertainty-driven R&D project.

Green transition and sustainability projects

Denmark places strong emphasis on sustainable innovation, and many environmental and climate-related projects can be treated as R&D. Examples include:

To qualify, these projects must involve systematic experimentation and not merely the adoption of existing green technologies that are already proven and documented.

Life sciences, biotech and medtech R&D

Companies in pharmaceuticals, biotechnology, medical devices and health technology often carry out intensive R&D. Typical qualifying activities include:

Regulatory work, routine quality control and standard clinical practice are generally not considered R&D unless they are directly linked to experimental development activities.

Experimental development and prototyping

A large share of qualifying R&D in Denmark falls under experimental development. This covers:

The key factor is that the work aims to generate new technical knowledge or apply existing knowledge in a novel way, rather than simply verifying that a known solution works as expected.

Supporting activities that can be included

Certain supporting tasks may also be treated as part of qualifying R&D when they are directly connected to an eligible project. These can include:

General administrative tasks, marketing studies, sales activities and routine training are not considered R&D and should be excluded from the tax relief calculation.

Distinguishing qualifying R&D from routine business activities

For Danish tax purposes, the distinction between qualifying R&D and normal operations is crucial. In assessing whether an activity qualifies, companies should consider:

Activities that simply apply established methods, follow standard industry practice or involve routine improvements without uncertainty are typically not eligible. Clear internal documentation, including project descriptions, technical reports and time records, is essential to demonstrate that activities meet the Danish R&D criteria and to support tax relief claims.

Overview of SkatteFUNN: Denmark's Key R&D Tax Credit Program

Denmark offers a targeted tax incentive for companies investing in research and development, commonly referred to as the R&D tax credit scheme. Although it is sometimes compared to programs such as SkatteFUNN in other Nordic countries, the Danish regime has its own rules, terminology and administration under the Danish Tax Agency (Skattestyrelsen). Understanding how this scheme works is essential for maximizing cash flow and reducing the effective cost of innovation projects.

The Danish R&D tax incentive allows companies to obtain a cash refund of a portion of their tax loss that is attributable to qualifying research and development costs. Instead of waiting until the company becomes profitable, eligible businesses can convert part of their tax loss into an immediate payment from the tax authorities, subject to specific limits and conditions.

Core mechanism of the Danish R&D tax credit

The incentive is structured as a refund of corporate tax on tax losses generated by approved R&D expenses. In practice, this means:

The refund is capped by a maximum amount of R&D costs that can be converted each year. The ceiling is set per income year and applies per company (or per jointly taxed group, if applicable). Within this limit, the company can receive a cash payment equal to 22% of the qualifying loss related to R&D activities.

Who can benefit from the scheme

The program is open to Danish companies and foreign companies with a permanent establishment in Denmark that are subject to Danish corporate income tax. It is particularly attractive for:

There is no requirement that the company operates in a specific industry, as long as the activities meet the tax definition of research and development and are properly documented.

What types of costs are covered

The Danish R&D tax credit focuses on costs that are directly linked to systematic and innovative activities. Typical qualifying expenses include:

Routine quality control, market research, sales activities and standard customization for individual customers do not qualify as R&D and should be kept separate from eligible costs.

Key advantages for companies

The Danish R&D tax credit scheme offers several concrete benefits:

Administrative process and documentation

The R&D tax credit is claimed through the annual corporate tax return. Companies must:

The Danish Tax Agency may request additional information or perform audits to verify that the activities and costs meet the statutory requirements. Well-structured project descriptions, time sheets and accounting records significantly reduce the risk of adjustments.

Strategic use of the R&D tax credit

For companies planning their innovation strategy, the Danish R&D tax scheme can be integrated into financial and tax planning. By mapping development projects against the rules and limits, businesses can:

Close coordination between finance, tax and R&D teams helps ensure that all eligible costs are captured and that the company makes full use of the available tax relief while remaining compliant with Danish regulations.

How to Apply for Tax Relief on Research and Development Expenses

Applying for tax relief on research and development expenses in Denmark requires careful planning, accurate documentation and timely filing. Although the rules are relatively clear, the process can be demanding, especially for companies claiming the R&D uplift and the cash refund of tax losses. Below is a practical, step-by-step overview of how to prepare and submit a compliant claim for the 2026 income year.

1. Map your R&D projects and costs

The first step is to identify which activities and costs qualify as research and development under Danish tax rules. You should:

From a tax perspective, you must be able to demonstrate that the work is aimed at developing new or significantly improved products, services, processes or technologies, and that the outcome could not be reliably predicted in advance.

2. Classify eligible R&D expenses

Once projects are defined, classify the related expenses that may qualify for tax relief. Typically eligible categories include:

Keep a clear distinction between R&D costs and general overheads. Overheads may be included only if you can allocate them to R&D on a consistent and well-documented method, for example via a cost-center structure.

3. Set up documentation and time-tracking

Strong documentation is essential to secure and defend your tax relief. Before the income year closes, ensure that you have:

In the event of a tax audit, the Danish Tax Agency will expect you to provide this documentation to substantiate both the R&D nature of the work and the amount of the claimed costs.

4. Calculate the R&D uplift and potential cash refund

Danish tax rules allow an uplift of qualifying R&D costs when calculating taxable income. In practice, this means you can deduct more than 100% of eligible R&D expenses, within the limits set by current legislation. You should:

The calculation should be prepared in a format that can be reconciled directly to your general ledger and annual financial statements.

5. Integrate the claim into the corporate tax return

Tax relief for R&D is claimed through the standard Danish corporate income tax return (selskabsselvangivelse). There is no separate stand-alone form, but you must:

For groups, verify that intra-group allocations of R&D costs and funding are consistent with transfer pricing documentation and that no double counting occurs across entities.

6. Prepare supporting schedules for Skattestyrelsen

Although you submit only summary figures via TastSelv Erhverv, it is good practice to prepare detailed internal schedules that can be shared with the Danish Tax Agency on request. These should include:

Having these schedules ready significantly reduces the time and risk associated with potential queries or audits.

7. Submit electronically via TastSelv Erhverv

Corporate tax returns, including R&D claims, are filed electronically through the TastSelv Erhverv portal. To complete the process, you must:

  1. Log in with the company’s NemID/MitID Erhverv credentials or via an authorized representative
  2. Fill in the corporate tax return for the relevant income year, ensuring that R&D fields are correctly populated
  3. Attach any required supplementary forms or statements if requested by the system
  4. Review all entries carefully, paying particular attention to the R&D uplift and any requested cash refund
  5. Submit the return and save the confirmation and a PDF copy for your records

If you use accounting or tax software integrated with TastSelv Erhverv, verify that the mapping of R&D accounts to the tax return fields is up to date before submission.

8. Observe statutory deadlines

The deadline for filing the corporate tax return, including the R&D claim, depends on the company’s financial year. As a rule, the return must be filed several months after the end of the income year. Missing the deadline can lead to loss or postponement of the cash refund and may trigger penalties or interest. It is therefore advisable to:

9. Respond to questions and audits

After filing, the Danish Tax Agency may request additional information or open a review of your R&D claim. To handle this efficiently:

Well-prepared documentation and consistent explanations significantly increase the likelihood that your R&D tax relief will be accepted without adjustments.

10. Review and optimize your R&D tax position annually

Finally, treat the application process as an annual cycle rather than a one-off exercise. Each year, you should:

By integrating R&D tax considerations into your financial planning and project management, you can maximize available tax relief while remaining fully compliant with Danish regulations.

Important Deadlines and Filing Procedures for R&D Tax Relief

To benefit fully from Danish tax relief on research and development costs, it is essential to follow the correct filing procedures and respect all statutory deadlines. The rules apply both to the immediate deduction of R&D costs and to the optional R&D uplift scheme, under which qualifying R&D salary costs can be deducted at 108% up to a ceiling of DKK 50 million per income year per group.

Key annual deadlines for R&D tax relief

In Denmark, the timing of your R&D tax relief claim is closely linked to your corporate income tax return. For companies with a standard calendar financial year, the most important deadlines are:

If your company uses a non‑calendar financial year, the same rules apply, but all deadlines are calculated from your specific year‑end. It is therefore important to align your internal R&D reporting with your statutory closing and tax filing timetable.

Step‑by‑step filing procedure

The process of claiming tax relief for R&D costs in Denmark is integrated into the ordinary corporate tax compliance workflow. In practice, it usually involves the following steps:

  1. Identify qualifying R&D projects
    Before preparing the tax return, the company should identify which activities meet the Danish definition of research and development. This typically includes systematic and innovative work aimed at developing new or significantly improved products, processes or services, and excludes routine adaptations or purely commercial activities.
  2. Classify and document R&D costs
    Eligible costs are then allocated to the identified R&D projects. Common categories include:
    • Gross salaries, pensions and social security contributions for employees directly engaged in R&D
    • Depreciation of equipment and software used in R&D
    • Consumables and materials used in experiments and testing
    • External R&D services and consultancy directly linked to the projects
    For each project, the company should maintain time records, internal project descriptions, budgets, and contracts with external suppliers to substantiate the R&D nature of the work and the allocation of costs.
  3. Calculate the R&D uplift
    For qualifying salary costs, the company may apply a 108% deduction instead of 100%, subject to a maximum base of DKK 50 million per income year per group. This means:
    • If eligible R&D salary costs are DKK 20 million, the deductible amount is DKK 21.6 million.
    • If eligible R&D salary costs are DKK 60 million, the uplift is capped at DKK 50 million, so the maximum deduction is DKK 54 million.
    The uplift is applied only to costs that meet the R&D criteria and are properly documented.
  4. Complete the corporate tax return in TastSelv Erhverv
    The Danish corporate tax return is filed electronically via the TastSelv Erhverv portal of the Danish Tax Agency (Skattestyrelsen). R&D costs and the uplift are reported in the specific fields for tax adjustments and additional deductions. The company must ensure that:
    • All R&D costs are correctly classified as deductible operating expenses or depreciable assets.
    • The 108% uplift is clearly indicated and reconciled with the underlying documentation.
    • Any group‑wide allocation of R&D costs is consistent with transfer pricing documentation.
  5. Submit supporting documentation on request
    While detailed R&D documentation is not always filed together with the return, Skattestyrelsen may request it during a review or audit. Companies should therefore be prepared to provide:
    • Project descriptions explaining objectives, innovation level and technical uncertainties
    • Time sheets or other evidence of employee involvement in R&D
    • Invoices and contracts for external R&D services
    • Internal approvals and board minutes relating to major R&D initiatives

Coordination with other tax positions

When filing for R&D tax relief, it is important to ensure consistency with other elements of the tax return. In particular:

Practical recommendations for timely compliance

To avoid losing part of the available R&D tax relief due to missed deadlines or incomplete filings, Danish companies should:

By integrating these procedures into the standard financial closing and tax compliance process, companies operating in Denmark can maximise available R&D tax relief while remaining fully compliant with the requirements of the Danish Tax Agency.

Future Changes and Expectations for R&D Tax Incentives in Denmark Post-2026

Looking beyond 2026, Danish R&D tax incentives are expected to remain a central tool for supporting innovation, but the detailed framework may evolve in response to fiscal policy, EU rules and international tax developments. Companies that plan multi‑year research and development projects should therefore treat the current rules as a solid, but not static, foundation and actively monitor potential adjustments to deduction rates, refund mechanisms and documentation standards.

At present, businesses can obtain an enhanced deduction of 108% of qualifying R&D costs and, for loss‑making companies, a cash refund of up to 22% of negative taxable income attributable to R&D, capped at DKK 25 million of R&D expenditure per income year. Any post‑2026 reform is likely to focus on how generous these parameters should remain and how they interact with broader corporate tax policy, including the implementation of global minimum tax rules.

One realistic scenario is a gradual recalibration of the 108% super‑deduction. Lawmakers may consider either extending the current uplift, returning to a 100% deduction for certain categories of expenditure, or introducing differentiated rates depending on the type of R&D activity, the size of the company or the sector. For example, a higher uplift could be reserved for activities that align with national priorities such as green transition, life sciences or advanced digital technologies, while routine development work might receive only a standard deduction.

Another area where change is likely concerns the cash refund for loss‑making companies. The current framework allows an effective cash benefit of up to DKK 5.5 million per year (22% of DKK 25 million in eligible R&D costs). Future reforms may adjust this ceiling, either to strengthen liquidity support for early‑stage companies or to limit the fiscal cost of the scheme. Policymakers could also refine the link between the refund and documented R&D risk, for instance by tightening the definition of qualifying projects or by requiring more granular cost allocation between R&D and non‑R&D activities.

In line with international trends, Danish authorities are also expected to increase their focus on the quality and traceability of R&D documentation. This may translate into more detailed guidance on project descriptions, time‑tracking, cost classification and internal controls, as well as a higher likelihood of targeted audits for companies claiming substantial R&D benefits. Businesses should anticipate stricter expectations around contemporaneous documentation that clearly demonstrates technological uncertainty, systematic experimentation and the direct link between costs and specific R&D projects.

Digitalisation of tax administration is another driver of change. Over time, the application and reporting process for R&D tax relief is likely to become more integrated with online filing systems, with structured data fields for R&D costs, automated cross‑checks against payroll and financial statements, and possibly pre‑validation tools that flag inconsistencies before submission. This can make compliance more efficient for well‑prepared companies, but it will also expose weak or inconsistent R&D records more quickly.

The interaction between Danish R&D incentives and international tax rules will remain an important theme. The introduction of global minimum taxation and evolving EU guidance on state aid may influence how generous national R&D regimes can be, and how benefits are calculated for multinational groups. Companies operating across borders should expect closer scrutiny of transfer pricing for R&D activities, ownership of intellectual property and the location of key development functions, as these factors can affect both eligibility for Danish incentives and the overall effective tax rate.

From a strategic perspective, businesses should not wait for formal legislative changes to adjust their approach. Long‑term R&D planning should include scenario analysis that tests the impact of possible reductions or enhancements in the super‑deduction, changes to refund caps and stricter documentation requirements. It is also prudent to build internal processes that can quickly adapt to new rules, for example by centralising R&D cost tracking, standardising project descriptions and ensuring that finance, tax and technical teams collaborate closely.

Professional advice will remain valuable in navigating this evolving landscape. A proactive review of your current R&D portfolio, claim history and documentation standards can help identify both risks and opportunities under potential post‑2026 rules. By aligning internal processes with best practice now, companies can maximise the benefits of existing incentives while remaining well positioned to respond to future changes in Denmark’s R&D tax framework.
