Denmark Tax Audit & Appeals Guide
SKAT selects taxpayers for audit based on risk assessment, industry profiling, and random sampling. If you disagree with SKAT's decision, you have 3 months to appeal to the independent Danish Tax Appeals Agency (Skatteankestyrelsen). Cases of principle proceed to the National Tax Tribunal (Landsskatteretten). Appeal fees start at DKK 1,300. For the full court litigation pathway — Landsskatteretten, Sø- og Handelsretten, Højesteret, and CJEU references — see our Tax Litigation and Courts Guide →.

SKAT Tax Audits (Skattekontrol)
The Danish Tax Agency (Skattestyrelsen) conducts tax audits to verify that taxpayers have reported correct income, deductions, and VAT. Audits are selected based on:
- Risk assessment: SKAT uses data-driven models to flag anomalies (e.g., unusual deductions, mismatches between reported income and third-party data from banks, employers, and digital platforms).
- Industry profiling: Certain sectors face higher audit frequency (construction, financial services, cross-border activities, transfer pricing).
- Random sampling: A portion of audits are randomly selected to maintain broad compliance coverage.
- Tip-offs and whistleblowing: SKAT investigates reports from the public, competitors, and former employees.
- Cross-border focus: Increased scrutiny on transactions involving low-tax jurisdictions, transfer pricing, and expatriate employees.
Audit Process
- Notification letter: SKAT sends an electronic letter (Digital Post) stating the scope of the audit, the tax years under review, and a request for specific information/documents. A deadline is set for the response.
- Information requests: SKAT may request accounting records, invoices, contracts, bank statements, board minutes, management reports, and other relevant documentation. The taxpayer is responsible for gathering and submitting the requested materials. SKAT has extensive legal powers to demand information under the Skattekontrollov.
- On-site visits and dawn raids: For serious non-compliance, SKAT may conduct unannounced on-site inspections, sometimes jointly with other authorities (police, immigration, Labour Market authority).
- Preliminary assessment (varsel om ændring): If SKAT concludes that reported taxes are incorrect, they issue a preliminary assessment proposing changes to the tax return. The taxpayer is invited to comment (høringsfrist, typically 14-30 days). This is the taxpayer's opportunity to present counterarguments and evidence.
- Final decision: After considering the taxpayer's comments, SKAT issues a final decision. Key deadlines:
- Corporate income tax: preliminary assessment by 1 May in the 4th year after the income year (income year 2022 → 1 May 2026). Final decision by 1 August.
- Controlled transactions (transfer pricing): preliminary assessment by 1 May in the 6th year after the income year. Final decision by 1 August.
- These deadlines cannot be extended by SKAT, though practical flexibility is sometimes given if the taxpayer needs more time.
Taxpayer Rights During an Audit
Danish administrative law guarantees certain taxpayer rights during a tax audit:
- Right to be heard (partsaktindsigt): You have the right to access the documents that SKAT relies on in forming its assessment. Before any adverse decision, SKAT must provide a draft (varsel) and give you a reasonable deadline to respond.
- Representation: You may be represented by a tax advisor, lawyer, or accountant throughout the audit. All correspondence should be directed to your representative if appointed.
- Proportionality: SKAT's audit activities must be proportionate to the perceived risk. Invasive techniques (dawn raids, extensive document requests) should be limited in scope and duration.
- Guidance obligation (vejledningspligt): SKAT has a duty to guide taxpayers on their procedural rights and obligations, though not on substantive tax planning.
- Statute of limitations: SKAT generally cannot make assessments for tax years more than 3 years old (ordinary reassessment deadline under Skatteforvaltningsloven §26). Extended to 6 years for controlled transactions (transfer pricing) and for cases involving gross negligence or fraud (§27).
Penalties and Interest
- Negligence (groft uagtsomt): If the incorrect reporting is due to gross negligence, penalties of up to 60% of the underpaid tax may apply (SKAT's administrative penalty scale was tightened from 1 March 2026).
- Intentional (forsætligt): For intentional tax evasion, criminal prosecution with higher fines and potential imprisonment. The penalty rate can reach 100%+.
- Standard errors: If no negligence is involved, only the underpaid tax plus interest is charged (no penalty).
- Interest (dag-til-dag rente): SKAT charges daily interest on underpaid tax from the original due date. The rate is set quarterly and was approximately 7-8% in 2026 (follows the Danish discount rate + a surcharge).
Appeals Process
If you disagree with SKAT's decision, you have the right to appeal. The Danish tax appeals system operates at three levels:
Step 1: Appeal to Skatteankestyrelsen (Tax Appeals Agency)
- Deadline: 3 months from the date you received SKAT's decision (Skatteforvaltningsloven §35 a, stk. 3). Late appeals may be accepted if there are reasonable grounds for the delay.
- Filing: Appeals are submitted via the online appeal form on Skatteankestyrelsen's website (Danish only). Taxpayers without MitID may submit by mail or in person.
- Fee: DKK 1,300 for most cases; DKK 600 for property assessment appeals. The fee must be paid at the time of submission or the appeal lapses.
- Processing: Skatteankestyrelsen is an independent authority under the Ministry of Taxation. It reviews the case, gathers additional information if needed, and either decides the case itself or prepares it for the National Tax Tribunal (Landsskatteretten).
- Caseload: As of 2026, Skatteankestyrelsen handles most routine appeals directly. Landsskatteretten handles cases of principle, significant amounts, or where the taxpayer requests tribunal review.
Step 2: Landsskatteretten (National Tax Tribunal)
- Scope: Hears appeals on taxation, VAT, duties, customs, property assessments, and debt collection. Its decisions on matters of principle set precedents.
- Composition: The tribunal includes legally qualified judges and independent experts (tax specialists, appraisers).
- Processing time: Historically 12-27 months, though Skatteankestyrelsen has worked to reduce this. The National Audit Office criticised the 27-month average in 2016; current processing times remain a concern.
Step 3: Court System
- Byret (District Court): First instance for tax cases. SKAT's or Landsskatteretten's decision can be challenged in the district court.
- Landsret (High Court): Appeals from the district court. Cases of principle may be appealed directly to the Supreme Court.
- Højesteret (Supreme Court): Final instance. Permission required, granted only for cases of general public importance.
- Note: Legal costs in court cases can be substantial. Taxpayer-friendly cost rules mean that if you win, SKAT may be ordered to pay your legal costs, but this is not guaranteed.
Deferral of Payment During Appeal
- As a main rule, overdue tax must be paid even if the assessment is under appeal.
- The taxpayer may request a deferral (henstand) from SKAT for the specific amount in dispute. A general deferral for the full assessment is not possible.
- If deferral is granted, interest accrues on the unpaid amount until payment is made.
- SKAT may require a bank guarantee as security for the deferred amount.
- Deferral decisions are discretionary — SKAT considers the likelihood of the taxpayer succeeding on appeal and the risk of non-payment.
Complaints About Case Handling
If you are dissatisfied with how SKAT handled your case (e.g., excessive delays, rude treatment, procedural errors) rather than the decision itself, you may file a complaint with SKAT's internal complaint handling or with the Folketingets Ombudsmand (Parliamentary Ombudsman). The Ombudsman cannot change SKAT's decisions but can criticise procedures and recommend improvements.
Practical Tips
- Respond promptly: SKAT sets deadlines for information requests. Missing deadlines weakens your position and may trigger adverse inferences.
- Engage professional help early: A Danish tax advisor (revisor) or lawyer with SKAT experience can significantly improve your outcome, especially in complex audits (transfer pricing, cross-border issues, restructuring).
- Document everything: Keep a log of all communications with SKAT, including dates, names, and content of calls and meetings.
- Appeal within the deadline: The 3-month appeal deadline is strict. If you miss it, you lose the right to appeal the decision (unless extraordinary circumstances apply).
- Consider voluntary disclosure: If you discover an error in your tax return before SKAT does, a voluntary disclosure (selvangivelse) can reduce or eliminate penalties. The rules are strict — contact a professional immediately.
