Denmark Researcher Tax Scheme 48E

Denmark's marginal income tax rate can reach 56%. For most Danish residents, that is just how it is. But if you are a foreign employee arriving in Denmark with a high salary and no prior Danish tax residency, you may qualify for a flat rate of 27% — for up to seven years.

This is not a loophole. It is a deliberate government policy, codified in §48E of the Kildeskatteloven (Danish Tax Assessment Act), designed to attract international talent to Danish companies and research institutions. It is formally called the Researcher Tax Scheme or the Expatriate Tax Scheme.

If you qualify and do not enrol, you will pay tens of thousands of DKK more in tax every year than you are legally required to.

What the Scheme Is

Under §48E, qualifying foreign employees pay a flat income tax rate of 27% on their Danish salary — instead of the standard progressive rates that push most high earners to 37–56%.

The 8% AM-bidrag (labour market contribution) is applied first, as with the normal system. Then 27% is applied to the remaining income. There is no personal allowance under this scheme, and no progressive brackets.

Combined effective rate: 8% + (27% × 92%) = approximately 32.8% total on gross income.

At DKK 100,000/month gross, this means approximately DKK 32,800 total tax, leaving you with DKK 67,200. Under the standard system at the same income, you would pay closer to DKK 52,000–55,000 in combined tax, leaving DKK 45,000–48,000.

The difference over a full year: approximately DKK 230,000–270,000 in tax saved. Over seven years, the total saving for a high earner can exceed DKK 1.5 million.

Who Qualifies

All four conditions must be met simultaneously:

1. Salary threshold

Your guaranteed average monthly salary must equal or exceed DKK 65,400 after ATP deduction in 2026. This threshold is adjusted annually — the 2024 figure was DKK 75,300, 2025 was DKK 78,000, and 2026 dropped to DKK 65,400 following a legislative change that broadened the scheme's reach. Always verify the current year's threshold at skat.dk before applying.

The threshold applies to your guaranteed contractual salary — bonuses, equity, and variable pay cannot be used to meet it. The salary must be stated in your employment contract.

The threshold exists to prevent the scheme from being used for lower-wage roles. It is a hard cutoff: if your guaranteed salary falls below it, you do not qualify.

2. No Danish tax residency in the past 10 years

You must not have been a tax resident of Denmark in the 10-year period immediately preceding the start date of your Danish employment. A tax resident is anyone who has lived in Denmark for more than six months continuously, or who has maintained a "permanent home" in Denmark.

If you were an international student in Denmark for a short period, or visited briefly, consult a Danish tax advisor — the interpretation of "tax residency" has nuance.

3. Employment by a Danish company

You must be employed by a company that is registered in Denmark and subject to Danish withholding tax obligations. This includes Danish subsidiaries of foreign companies. It does not include remote arrangements where a foreign company is your employer but you work from Denmark.

4. Not previously applied the scheme

You can use §48E for a maximum of 84 months (7 years) across your lifetime of Danish employment. If you have used it in the past, even partially, the remaining eligibility is reduced accordingly.

What the 27% Rate Covers

The flat rate applies to:

• Base salary
• Holiday pay (feriepenge)
• Employer-paid insurance premiums (in some cases)

It does not apply to:

• Income from outside Denmark (foreign rental income, dividends from a non-Danish employer)
• Self-employment income
• Director fees above a certain threshold (these may be taxed differently)

What You Give Up

The §48E scheme has meaningful trade-offs.

No standard deductions

Under the normal tax system, you can deduct commuting costs, a-kasse contributions, union fees, mortgage interest, and charitable donations. Under §48E, none of these deductions are available. You pay 27% on the full A-income after AM-bidrag, regardless of expenses.

For someone with a large Danish mortgage, this can be significant. Mortgage interest deductibility in Denmark saves approximately 26–33% of the interest paid. On a DKK 5 million mortgage at 4% interest, that is DKK 200,000/year in interest, with a deduction worth DKK 52,000–66,000/year — gone under §48E.

Run the numbers for your specific situation before deciding.

Pension implications

Employer pension contributions in Denmark are substantial — typically 10–17% of gross salary. Under §48E, employer pension contributions are included in the taxable salary for the purposes of the scheme's salary threshold. However, the interaction with Danish pension rules and the eventual tax treatment of pension withdrawals is complex.

Non-Danish pension schemes may not be recognised. Consult a Danish tax advisor if your home country pension is involved.

Limit on duration

After 84 months, you automatically shift to the standard tax system. You cannot extend the scheme. Plan for the transition year — your effective tax rate will increase sharply.

How to Apply

The application is submitted by your employer, not by you directly. Here is the process:

1. Before or immediately upon starting employment: Discuss §48E eligibility with your HR or finance department. Not all Danish companies are familiar with the scheme — you may need to bring it to their attention.

2. Employer submits to Skattestyrelsen: Your employer files a registration with the Danish Tax Authority (Skattestyrelsen) on your behalf, using the official registration system. This can only be done within 6 months of your first day of Danish employment. If your employer misses this window, you lose the ability to apply for that employment period.

3. Application includes: Proof of your qualifying salary, employment contract confirming the terms, documentation that you have not been a Danish tax resident in the past 10 years (typically foreign tax records or passport history).

4. Approval: Skattestyrelsen reviews the application and issues confirmation. Once confirmed, your employer withholds at the flat rate from that point forward.

5. Retroactive adjustment: If the application is approved after you have been working for several months under the standard tax rate, the overpaid tax is adjusted through your annual tax return.

Is the Scheme Worth It? A Comparison

Annual Gross (DKK)	Standard Tax (approx)	§48E Tax (approx)	Annual Saving
DKK 960,000 (80k/mo)	DKK 480,000–510,000	DKK 315,000	DKK 165,000–195,000
DKK 1,200,000 (100k/mo)	DKK 620,000–660,000	DKK 394,000	DKK 226,000–266,000
DKK 1,800,000 (150k/mo)	DKK 960,000–1,020,000	DKK 590,000	DKK 370,000–430,000

These are approximations assuming average Copenhagen municipal tax and no major deductions under the standard system. A Danish tax advisor can run your specific numbers.

The break-even analysis: if your Danish mortgage interest deduction or other deductions would save you more than the scheme's tax advantage, the standard system might be better. For most high earners without a large Danish mortgage, §48E wins clearly.

Practical Steps When You Arrive

1. Check your salary against the threshold — DKK 65,400/month after ATP in 2026. If you are above it, proceed immediately.
2. Raise §48E with HR on your first day — not week two. The 6-month window sounds long but HR processes can be slow.
3. Confirm your Danish tax residency history — gather foreign tax returns or a statement from your home country's tax authority confirming you were not resident in Denmark in the past 10 years.
4. Get a Danish tax advisor for one session — a one-hour consultation (DKK 1,000–2,500) to verify you qualify and review the trade-offs against your specific deduction situation is worth it. The numbers are large enough that errors are expensive.
5. Do not start working and assume it will sort itself out — if your employer withholds at the standard rate and the 6-month window closes, you have missed the scheme permanently for that employment.

Key Takeaways

• §48E gives qualifying foreign employees a flat 27% income tax rate (plus 8% AM-bidrag) instead of the standard 37–56%.
• You must have a guaranteed average monthly salary of at least DKK 65,400 (after ATP, 2026 threshold), work for a Danish employer, and not have been a Danish tax resident in the past 10 years.
• The maximum duration is 84 months (7 years) across your lifetime.
• The scheme eliminates most standard deductions — run the numbers before deciding.
• Application must be submitted by your employer within 6 months of your start date. Miss the window and the opportunity is gone.
• The annual tax saving ranges from DKK 165,000 to DKK 430,000+ depending on salary. Take this seriously.
