Danish Researcher Tax Scheme (Forskerordning): 27% Flat Tax for Expats

Denmark’s progressive income tax system pushes marginal rates above 50% for high earners — unless you qualify for the Researcher Tax Scheme (Forskerordning). This scheme gives eligible expats a flat 27% income tax rate on employment income for up to 84 months, saving hundreds of thousands of kroner over the scheme’s duration. This guide covers who qualifies, how to apply, and what the scheme actually saves you.

What Is the Researcher Tax Scheme?

The Forskerordning is a special tax regime for qualifying researchers and highly paid employees who have recently arrived in Denmark. Instead of Denmark’s normal progressive tax rates (which can reach 52.5% at the top marginal rate), the scheme imposes a flat 27% income tax on employment income.

The full cost:

Without the scheme, a high earner faces marginal rates of 45–52.5% on employment income. With the scheme, your total tax burden is a flat 35%. The difference can amount to DKK 80,000–130,000 or more per year, depending on your salary.

Eligibility Requirements

Not everyone moving to Denmark qualifies. SKAT applies strict criteria:

• Newly arrived: You must not have been a Danish tax resident in any of the 10 calendar years preceding your arrival.
• Employment type: You must be employed by a Danish employer under a Danish employment contract.
• Salary threshold: Your minimum monthly salary must be at least DKK 65,400 (2026 figure). This threshold is adjusted annually.
• Role: You must be employed as a researcher, scientist, or in a highly qualified position. This includes university professors, corporate researchers, senior executives, and specialist consultants.

Who qualifies:

• University professors and researchers joining Danish institutions
• Corporate researchers and R&D specialists
• Senior executives and managers with high salaries
• Specialist consultants and contractors with Danish employment contracts

Who doesn’t qualify:

• Individuals who were Danish tax residents within the past 10 years
• Employees earning below the DKK 65,400/month threshold
• Self-employed individuals or contractors without a Danish employment contract
• People who have previously used the scheme without the required 10-year gap

Application Window: 1 Month — No Exceptions

This is the most critical rule. You must apply for the Researcher Tax Scheme within 1 month of your first day of employment in Denmark.

How to apply:

1. Log in to skat.dk using MitID (Danish national digital ID)
2. Navigate to the researcher scheme application
3. Submit your employment details and salary documentation
4. SKAT processes the application and applies the scheme from your start date

Late applications are typically rejected. SKAT does not grant extensions or retroactive applications. If you miss the 1-month window, you lose the scheme for the entire duration of your employment — there is no remedy.

Action item: If you are relocating to Denmark, initiate your MitID setup immediately upon arrival. The MitID registration process itself can take time, and you need it before you can apply on skat.dk.

What the Scheme Covers

The flat 27% tax applies only to employment income. This includes:

• Base salary
• Bonuses and commissions
• Benefits in kind (company car, phone, etc.)

What is NOT covered (taxed at normal progressive rates):

• Dividends
• Capital gains from investments
• Rental income
• Pension income
• Any other non-employment income

If you earn DKK 90,000/month in salary and DKK 10,000/month in dividends, only the salary portion gets the 27% flat rate. Dividends are taxed separately at the normal 27%/42% rates.

AM-Bidrag: The 8% You Still Pay

The scheme replaces income tax, not AM-bidrag. You still pay the 8% labour market contribution on top of the 27% flat tax.

Calculation:

• Gross salary: DKK 90,000
• AM-bidrag (8%): DKK 7,200
• Taxable income: DKK 82,800
• Income tax (27%): DKK 22,356
• Total deducted: DKK 29,556
• Net salary: DKK 60,444

Compare this to the standard regime without the scheme, where marginal rates climb to 52.5% for the same income level.

Duration: Up to 84 Months (7 Years)

The scheme lasts for a maximum of 84 months from your first day of Danish employment. Key points:

• The clock starts on your first day of work, not on the date of your tax residency application
• The 84-month period is continuous — it does not pause if you leave Denmark temporarily
• If you leave Denmark and return after 10+ years as a non-tax resident, you can apply again for a fresh 84-month period
• If you return within 10 years, you are not eligible for a new period

Interaction with Other Tax Benefits

The Researcher Tax Scheme does not eliminate your access to other Danish tax benefits. You can still:

• Claim pension contributions: Both employer and employee pension contributions continue as normal. Employer contributions are deductible, and employee contributions reduce your taxable income.
• Claim rentefradrag (interest deduction): If you have Danish mortgage debt or other qualifying loans, you can still deduct interest payments.
• Claim commuting deductions: Standard deductions for commuting to work still apply.
• Use fradrag for professional expenses: Deductions for work-related costs remain available.

The scheme layers on top of these deductions. Your 27% flat rate applies to your employment income after AM-bidrag, and standard deductions are applied within that framework.

Worked Example: DKK 90,000/Month Salary

Let’s compare a researcher earning DKK 90,000/month gross — DKK 1,080,000 annually.

Without the Scheme (Normal Progressive Tax)

(Approximate — actual figures depend on municipality, deductions, and church tax opt-in.)

With the Researcher Tax Scheme

Monthly saving: ~DKK 13,000 Annual saving: ~DKK 156,000 Over 84 months (7 years): ~DKK 1,092,000

At higher salary levels, the savings are even more dramatic. A senior executive earning DKK 150,000/month saves approximately DKK 250,000+ per year under the scheme.

Practical Tips for Expats

1. Apply immediately. The 1-month application window is strict. Do not delay. Begin your MitID registration the day you arrive.

2. Keep salary documentation. SKAT may request proof of your salary level to confirm you meet the DKK 65,400 threshold. Keep payslips and employment contracts on file.

3. Consider an accountant for your first year. The interaction between the scheme, AM-bidrag, pension contributions, and deductions can be complex. A Danish tax advisor experienced with expat cases can help you maximize your position.

4. Understand the scope. The scheme covers employment income only. If you have investments, rental income, or other Danish-sourced income, those are taxed at normal rates. Plan accordingly.

5. Track your 84 months. Mark your calendar. The scheme ends 84 months after your first day of Danish employment — not after you become a tax resident.

6. MitID is essential. You cannot apply on skat.dk without MitID. Start the process as soon as you have your CPR number.

Common Mistakes to Avoid

• Missing the 1-month deadline. There is no appeals process. If you apply on day 31, you lose the scheme entirely.
• Assuming all income is covered. Investment income, dividends, and rental income are taxed at normal rates. Only employment income benefits from the 27% flat rate.
• Forgetting AM-bidrag. The scheme does not eliminate the 8% labour market contribution. Your total tax rate is 35%, not 27%.
• Not having MitID ready. If you arrive in Denmark without MitID set up, you may struggle to apply within the 1-month window. MitID setup can take 1–2 weeks with a CPR number.
• Assuming the scheme is automatic. SKAT does not apply it proactively. You must file the application yourself.
