As of 17 August 2026 the Icelandic Tax Authority has published the 2025 individual tax assessment roll providing taxpayers with a mandated review period to examine their annual tax liability. This publication issued under the statutory framework of the Icelandic Tax Administration Act No 98/1998 encompasses all tax obligations and entitlements accrued during the 2025 tax year with the review window running exclusively from 17 August to 31 August 2026 inclusive. Taxpayers are notified that the assessment serves as the basis for final tax determination and any unchallenged amounts will be deemed accepted upon the expiry of the review period
Key Takeaways
- Mandatory Review Period Taxpayers must review their 2025 individual tax assessment between 17 August and 31 August 2026; failure to submit objections or corrections within this statutory window renders the assessment final and legally binding directly impacting annual tax liability and potential refunds.
- Digital Access and Correction The assessment roll is accessible via the Tax Authority’s official digital services and website allowing individuals to submit corrections objections or additional information online during the review period to ensure accurate tax treatment and avoid overpayment or underpayment of taxes.
- Adjustment and Appeals Process Any disputes regarding assessed amounts must be formally lodged in writing or through the Tax Authority’s electronic portal within the review period; late submissions are generally inadmissible underscoring the necessity of timely action to prevent adverse tax outcomes and potential interest accruals on disputed amounts
