Key takeaways
- In Denmark, giving the tax authority incorrect, misleading or incomplete information with intent to evade tax is "skattesvig" under section 82 of the Tax Control Act (Skattekontrolloven), punishable by a fine or up to 1 year and 6 months in prison.
- Particularly serious tax fraud falls under section 289 of the Danish Criminal Code (Straffeloven), which carries up to 8 years in prison; separately, in December 2024 a Danish court sentenced Sanjay Shah to 12 years for aggravated fraud in the dividend-tax refund case.
- Gross negligence is punished with a fine only, but it also lets the Danish Tax Agency reopen assessments beyond the normal deadline of 1 May in the fourth year after the income year.

What counts as tax fraud in Denmark?
Danish law separates three levels of non-compliance:
- Errors in good faith. The tax is corrected, with interest, but there is no penalty.
- Gross negligence (grov uagtsomhed). You should clearly have known the information was wrong, for example ignoring obvious foreign income. The sanction is a fine.
- Intent (forsæt). You knowingly gave wrong or incomplete information to reduce your tax. This is skattesvig, and prison is possible.
Under section 82 of the Tax Control Act, tax fraud is committed by anyone who, intending to evade tax, gives the tax authority incorrect, misleading or incomplete information used to decide tax liability or the assessment. You are only liable for information you must provide yourself or could correct on your annual information form (årsopgørelse/oplysningsskema), not for errors made by third parties reporting automatically on your behalf.
Section 83 adds a duty to act. Because most Danish tax returns are pre-filled, staying silent is also an offence: if your pre-filled assessment is too low, you must tell the Danish Tax Agency (Skattestyrelsen) within four weeks after the reporting deadline. If you receive no assessment or information form at all, you must file the required information yourself before the deadline.
Section 84 creates separate fine-only offences, committed intentionally or by gross negligence, such as:
- not reporting foreign pension schemes;
- failing to keep required records;
- failing to file transfer-pricing documentation or country-by-country reports on time;
- issuing, in business, an invoice with false content that could be used to calculate taxable income.
Tax avoidance (using the law as intended to reduce tax) is legal, but Denmark applies a general anti-abuse rule and specific rules on controlled transactions and residence. Arrangements whose main purpose is a tax advantage contrary to the purpose of the law can be disregarded, which leads to reassessment rather than criminal charges.
What are the penalties for tax fraud in Denmark?
Fines. Gross negligence is punished by a fine, and intentional fraud by a fine or prison. The statute does not set a fixed amount: fines are fixed by the courts or accepted administratively, usually as a multiple of the evaded tax. In practice, intentional evasion is fined at about 2x the evaded tax, and gross negligence at about 1x – reduced to 50% of the evaded tax on the first DKK 60,000 for a first offence.
Prison under the Tax Control Act. Intentional tax fraud carries up to 1 year and 6 months. Prison sentences are generally reserved for large evaded amounts or repeated conduct; particularly serious cases can be prosecuted under section 289 of the Criminal Code (up to 8 years).
Prison under the Criminal Code. Section 289 of the Straffeloven applies to violations of a particularly serious nature of tax, customs, excise or subsidy legislation committed to obtain an unjustified gain, with up to 8 years in prison. When setting a supplementary fine, the court weighs whether the offence was especially serious due to the method used, the number of people involved or the number of offences.
The Shah case. In the largest fraud case in Danish history, Sanjay Shah was sentenced in December 2024 to 12 years in prison over the dividend-tax refund (cum-ex style) scheme run from 2012 to 2015. Assets worth about DKK 7.2 billion were ordered confiscated, and he was permanently banned from entering Denmark. He was convicted of aggravated fraud (Straffeloven §279, cf. §286(2), maximum 8 years), and the sentence reached 12 years because section 88 allows the maximum to be increased by up to half when several offences are sentenced together. Shah appealed, and the appeal trial before the Eastern High Court (Østre Landsret) is scheduled to start in November 2026; he remains in custody in Denmark.
Other consequences. On top of criminal sanctions, the evaded tax is reassessed with interest, and company directors and bookkeepers who participate can be charged as accomplices.
How are tax fraud cases investigated and prosecuted?
- Control by Skattestyrelsen. The Danish Tax Agency compares returns with third-party data (employers, banks, platforms, foreign exchanges of information under CRS and DAC) and opens a control case.
- Reassessment. The agency sends a proposal (agterskrivelse) and then a decision. You have the right to comment and to see the case file.
- Penalty assessment. If it suspects gross negligence or intent, the agency's criminal unit can offer an administrative fine. If you accept, the case is closed.
- Police and prosecution. If you refuse the fine, or the case is serious, it goes to the police. The National Unit for Special Crime (NSK) handles the largest economic crime cases.
- Court and appeal. Criminal cases are heard by the district court (byret) and can be appealed to the High Court (landsret). Tax reassessments themselves are appealed separately, to the Danish Tax Appeals Agency and Tax Tribunal (Skatteankestyrelsen/Landsskatteretten) or the courts.
Example. A Danish-resident freelance consultant invoices EUR 80,000 a year through a foreign platform and omits EUR 20,000 for three years. If the agency finds the omission grossly negligent, it can reopen all three years under section 27, even after the ordinary deadline, and impose a fine. If emails show he deliberately routed income abroad to keep it off his return, the case becomes intentional skattesvig, with prison possible.
How long can Denmark go back?
There are two different clocks:
- Tax reassessment. The ordinary deadline is notice by 1 May and a decision by 1 August of the fourth year after the income year (for income year 2022, by 1 May 2026). Where the taxpayer acted intentionally or with gross negligence, section 27 allows reassessment beyond that deadline, provided the agency gives notice within 6 months of learning the relevant facts. No fixed outer limit in years appears in the section.
- Criminal prosecution. Under Straffeloven §93, offences with a maximum of up to 4 years' prison become time-barred after 5 years, and those with a maximum of up to 10 years after 10 years. In practice, tax fraud under the Tax Control Act therefore runs on a 5-year clock, and particularly serious fraud under §289 on a 10-year clock.
What should location-independent professionals watch in Denmark?
Most tax fraud cases involving mobile professionals start with residence, not with hidden cash.
- Residence and departure. You can remain fully taxable in Denmark if you keep a home available there, even while living abroad. Moving out without giving up your Danish home, or misreporting your departure date, is a classic source of reassessment. See our practical guide to ceasing your tax residency in Denmark and the rules on tax residency in Denmark.
- Foreign income and accounts. Denmark receives automatic information on foreign bank accounts, investment income and platform income. Foreign salary, freelance invoices, crypto gains and foreign pensions must be declared. The duty to report a too-low pre-filled assessment applies to all of them.
- Foreign companies. A foreign company managed from Denmark can be treated as Danish tax resident, and its income taxed in Denmark. Presenting it as foreign while you run it from Copenhagen is a requalification risk, and potentially a fraud risk if facts are misrepresented. Our guide to legal forms of business in Denmark explains the local alternatives.
- Special regimes. If you moved to Denmark under the researcher and key employee scheme, check that its conditions are met. Claiming a regime you do not qualify for creates back-tax exposure. See tax incentives for expats in Denmark.
What to do if you find an error. Correct it before the agency contacts you. You must notify the agency anyway when your assessment is too low, and correcting voluntarily is a strong mitigating factor when the authorities decide whether to pursue a penalty.
Frequently asked questions
What is the penalty for tax fraud in Denmark?
Intentional tax fraud under section 82 of the Tax Control Act is punished by a fine or up to 1 year and 6 months in prison. Gross negligence is punished by a fine only. Particularly serious cases fall under section 289 of the Criminal Code, with up to 8 years in prison. The evaded tax must also be repaid with interest after reassessment.
What is tax compliance in Denmark?
Tax compliance in Denmark means checking your pre-filled tax assessment each year, adding any missing income such as foreign salary, freelance invoices, investment or crypto gains, and notifying the Danish Tax Agency within four weeks if the assessment is too low. Businesses must also keep records and file documentation on time. Failing to do so can lead to fines, reassessment and, if intentional, criminal charges.
How many years back can the Danish Tax Agency go?
Ordinarily, the agency must give notice by 1 May of the fourth year after the income year and decide by 1 August. If you acted intentionally or with gross negligence, it can reopen older years, provided it gives notice within six months of learning the facts. Criminal liability is separately time-barred after 5 years for ordinary tax fraud and 10 years for particularly serious fraud.
Is tax avoidance illegal in Denmark?
No. Legal tax planning that uses the rules as intended is allowed. However, Denmark applies a general anti-abuse rule and specific rules on residence and controlled transactions, so arrangements mainly aimed at a tax advantage contrary to the purpose of the law can be disregarded. That leads to reassessment and interest, and to penalties only if you gave incorrect or incomplete information.
Who prosecutes tax fraud in Denmark?
The Danish Tax Agency (Skattestyrelsen) detects and assesses cases and can offer an administrative fine. If the fine is refused or the case is serious, it is passed to the police and prosecution service; the largest economic crime cases go to the National Unit for Special Crime (NSK). Criminal cases are tried in the district court and can be appealed to the High Court.
