If you are a recruiter placing consultants in Norway, or an international consultant working here, the Norwegian tax return is worth paying close attention to.

Most people earning taxable income in Norway must submit a tax return, unless they are taxed under the PAYE scheme. For the 2025 income year, the filing deadline was 30 April 2026.

But the most important point is this: the tax deducted from your salary during the year is only an estimate.

Your Norwegian tax card is based on expected income and information available when the tax card is issued. If your actual income, working pattern or personal circumstances change during the year, the amount deducted may not reflect your final tax liability.

This is particularly relevant for international consultants, whose circumstances can often be more complex. You may have paid too little tax and receive an additional tax bill. Alternatively, you may have paid too much tax or missed deductions that could reduce your final tax liability.

For consultants working across borders, differences commonly arise from:

• Incorrect income estimates when the tax card was issued
• Changes in tax residency or length of stay in Norway
• Deductions that have not been included or claimed
• Travel and accommodation arrangements
• Changes to the assignment during the income year

Commuter deductions can make a significant difference

Some international workers may qualify as commuters for Norwegian tax purposes.

Depending on the circumstances, this can give entitlement to deductions relating to travel between Norway and the home country, accommodation in Norway and, in some cases, additional food expenses.

For the consultant, these deductions may significantly improve the final tax position and increase effective net income.

For recruitment agencies, understanding these rules can also be commercially important. Two assignments with the same gross salary can produce very different outcomes for the consultant depending on how the assignment, travel and accommodation are structured. Helping a candidate understand their likely net position can therefore make an offer more attractive and reduce unpleasant surprises later.

Your tax return is not necessarily final when you receive it

Statistics from recent Norwegian tax settlements show that a significant number of taxpayers initially receive an assessment indicating tax arrears, while some subsequently improve their position after reviewing and correcting their tax return.

This underlines why the tax return should be treated as something to review, rather than simply accept. Even after the ordinary filing deadline has passed, it may still be possible to make changes to a Norwegian tax return.
