What is this right?
As a taxpayer you have certain rights during a tax audit:
- Written notification: Audits are conducted through formal written communication under strict procedural rules.
- Right to a representative: A representative (an accountant or lawyer) can act on your behalf with a written authorisation.
- Right of appeal: You can challenge the audit findings through the same two-step administrative appeal route (Skatturinn, then the State Tax Board of Appeals) plus two court levels.
Limitation period for reassessment:
- 2 years — if you filed your return correctly with all the necessary information.
- 6 years — the general limitation period.
- 10 years — for income and assets in low-tax countries.
When does it apply?
- Skatturinn selects your return for review — either by electronic screening or a formal audit programme.
- Audits can last from a few weeks to more than a year.
What to do if Skatturinn is auditing your tax return in Iceland
- Respond to all written communication from Skatturinn within the specified deadlines.
- Consider hiring a tax adviser or accountant to assist you.
- Keep all records organised — payslips, receipts, bank statements and previous tax returns.
What should you NOT do?
- Don't ignore communication from Skatturinn — failing to respond can lead to an estimated assessment that may be higher than your actual liability.
- Don't destroy records — you should keep tax records for at least 6 years.
About Tax Rights in Iceland
Income tax in Iceland is progressive in three brackets under lög um tekjuskatt (the Income Tax Act, Lög nr. 90/2003) and combines state tax and municipal tax (~14.94%). All residents aged 16 and over receive a personal tax credit (persónuafsláttur) that is transferable between spouses. Capital income is taxed at 22%. VAT (Lög nr. 50/1988) is 24% standard and 11% reduced — businesses register once turnover exceeds 2 million kr. Skatturinn (the tax authority) handles the assessment. You can appeal to yfirskattanefnd (the State Tax Board of Appeals) and from there to the district courts. Employers pay a social security contribution (tryggingagjald) under Lög nr. 113/1990.
