📅 The Norwegian Tax Year
The Norwegian tax year runs from January 1 to December 31. Unlike some countries with fiscal years, Norway’s system follows the calendar year, making it easier to align tax obligations with annual income and expenses.
📝 Filing Deadlines
The filing process in Norway is unique because many taxpayers receive a pre-drafted tax return (skattemelding) from the Norwegian Tax Administration. Here’s how the deadlines work:
- Tax Return Distribution: Pre-filled returns are usually available in March or April.
- Ordinary Filing Deadline: April 30 of the year following the income year.
- Extension: Taxpayers can apply for an extension (typically up to one month) if more time is needed.
- PAYE Workers: Those under the PAYE scheme usually don’t need to file a return unless corrections are necessary.

💳 Payment Rules
Norway operates a pay-as-you-earn (PAYE) system for most employees, meaning taxes are withheld directly from salary. For others, advance payments may apply:
- PAYE Employees: Tax is final at the time of payment; no annual return required unless adjustments are needed.
- Ordinary Taxpayers: Advance tax is paid in four installments – March 15, May 15, September 15, and November 15.
- Final Settlement: If taxes withheld were too low, the difference must be paid in two installments, 3 and 8 weeks after the assessment notice.
- Refunds: Overpaid taxes are refunded with interest, usually between June and October.
Missing deadlines or underpaying taxes can lead to penalties:
- Late Filing Penalty: Additional tax (up to 20%) may apply if you fail to submit corrections.
- Late Payment Interest: Charged on outstanding amounts; can be avoided by paying estimated taxes early.
- Audit Risks: Errors or missing information may trigger manual reviews or audits.
🔍 Tips for a Smooth Filing
- Check that your pre-filled tax return includes all income sources (salary, pensions, capital gains, etc.).
- Keep records of deductions such as mortgage interest, union dues, and charitable contributions.
- If you had foreign income, ensure foreign tax credits are correctly applied.
- Apply for an extension if you cannot meet the April 30 deadline.
- Use updated tax software or consult a tax expert to avoid mistakes.
✅ Conclusion
Understanding how the Norwegian tax year works helps you stay compliant and avoid unnecessary penalties. Whether you’re a resident taxpayer or a non-resident under PAYE, knowing the deadlines, payment rules, and filing requirements ensures peace of mind and potential savings in 2025 and 2026.
