Learn › Filing your tax return in Norway

In short: In Norway you do not usually fill in a tax return from scratch. Skatteetaten sends you a pre-filled return (skattemelding) in March or April. You log in, check that the income, deductions, wealth and debt are correct, fix anything that is wrong, and submit by 30 April. As of 2026, if you make no changes and do nothing, the pre-filled return is automatically treated as submitted. The tax assessment notice (skatteoppgjør) that shows any refund or underpaid tax then arrives between April and the autumn, and everyone receives it before 1 December.

Filing your tax return in Norway

Kontoo editorial team · Updated 06/24/2026

In Norway you rarely start a tax return from a blank page. Each spring the Norwegian Tax Administration (Skatteetaten) sends you a pre-filled tax return, the skattemelding, with the income, deductions, wealth and debt it already knows about. Your job is to check it, fix anything wrong, and submit by the deadline. This lesson explains the rhythm of the Norwegian tax year so the process feels routine rather than stressful. It is educational information, not tax advice.

Wait for your skattemelding. In March or April, Skatteetaten notifies you by email or text that your pre-filled tax return is ready. Log in at skatteetaten.no using an electronic ID (such as BankID) to view it.
Check every figure. Compare the pre-filled salary, pension, interest, deductions, wealth and debt against your own records and annual statements from employers and banks. Most numbers are reported automatically, but gaps happen.
Correct and add what is missing. If something is wrong or absent, edit it directly in the return. You can add deductions you are entitled to and remove items that do not apply, then submit.
Submit by 30 April. As of 2026, the deadline to change and submit is 30 April for wage earners and pensioners. If you do nothing, Skatteetaten treats the pre-filled version as your submitted return.

What matters

Norway runs one of the most automated personal tax systems in Europe, which is why the experience is closer to reviewing a statement than completing a form. Throughout the year, employers, banks, NAV and other bodies report your income, interest, wealth and debt directly to Skatteetaten. Each spring that data is assembled into your skattemelding, the pre-filled tax return. You are notified in March or April by email or text. Logging in with an electronic ID such as BankID shows the return with the figures Skatteetaten already holds. The core task is verification: does the listed salary match your payslips, are the bank interest and loan figures right, and are all the deductions you are entitled to actually present? Common items people add or adjust include commuting deductions, interest on loans, donations to approved organisations, and changes after buying or selling property. The deadline to change and submit is 30 April for wage earners and pensioners (as of 2026). A defining feature of the Norwegian system is silent submission: if you do not act, the pre-filled return is treated as submitted on the deadline. This is convenient when everything is correct, but it means you must still review the return rather than assume it is complete. If you need longer, you can apply for a 30-day extension by 30 April; the self-employed have a 31 May deadline. After submission, processing leads to the skatteoppgjør, the tax assessment notice. It confirms your final tax and shows either a refund or underpaid (residual) tax. These notices roll out from around April through the autumn, and everyone receives theirs before 1 December. Keeping clean records during the year is the single best way to make the spring check fast and accurate.

ExampleSuppose your skattemelding lists a gross salary of NOK 650,000 and the tax already deducted through the year totals NOK 165,000. You notice a deductible loan-interest cost of NOK 40,000 that lowers your taxable income, plus a commuting deduction of NOK 8,000, neither fully reflected. After you add these and the return is assessed, your calculated tax falls to, say, about NOK 150,000. Because NOK 165,000 was withheld, the tax assessment notice would show a refund of roughly NOK 15,000. These are rounded illustrative figures only; your real result depends on current rates and your full situation. As of 2026, check the official source when in doubt.

Use the Kontoo budget planner to keep a tidy yearly record of deductible costs (such as commuting or loan interest) so checking your skattemelding takes minutes. The official portal is skatteetaten.no.

In depth

Why Norway pre-fills your return

Third-party reporting is the backbone of the system. Employers, banks, pension providers and public bodies send data straight to Skatteetaten, so most taxpayers only verify rather than enter figures. This reduces errors and effort, but it shifts responsibility to you to spot what the data does not capture, such as eligible deductions or changes the authorities have not yet recorded.

From submission to assessment

Submitting (or letting the pre-filled return stand) is only the first half. Skatteetaten then calculates your final tax and issues the skatteoppgjør, the tax assessment notice, showing a refund or underpaid tax. As of 2026 these are issued from roughly April through autumn, with everyone receiving one before 1 December. If you owe tax, plan for the payment; if you are due a refund, it follows once your assessment is ready.

Checklist

Did you log in at skatteetaten.no and open your pre-filled skattemelding?
Did you compare every figure (income, interest, wealth, debt) against your own statements?
Did you add any deductions you are entitled to and remove anything incorrect?
Did you submit, or confirm the pre-filled version, by 30 April (or apply for the 30-day extension)?

Common myths

Myth: If I ignore the tax return, I get in trouble.

Reality: As of 2026, doing nothing is allowed: Skatteetaten treats the pre-filled return as submitted. The real risk is not penalty but missing deductions or leaving errors uncorrected, which can cost you money.

Myth: The pre-filled numbers are always complete and correct.

Reality: Most figures are reported automatically, but deductions you qualify for, recent life changes, or foreign income may be missing. Skatteetaten asks you to check and correct it, which is why review still matters.

Frequently asked questions

What happens if I do not submit by 30 April?

As of 2026, if you do not actively submit, Skatteetaten considers the tax return submitted with the pre-filled information. That is fine if everything is correct, but you lose the chance to add missing deductions or fix errors on time. You can still correct returns for up to three earlier years afterwards. Check the official source at skatteetaten.no when in doubt.

Can I get more time?

Yes. As of 2026 you can apply for a 30-day extension, and the deadline to apply is also 30 April. Sole proprietorships (self-employed) have a later standard deadline of 31 May. Confirm current rules on skatteetaten.no.

When do I find out about a refund or extra tax owed?

After your return is processed, Skatteetaten sends a tax assessment notice (skatteoppgjør). Most people receive it between April and June, some not until autumn, and everyone before 1 December. It states any refund due to you or any underpaid tax you must pay.

How do I log in?

You access your skattemelding at skatteetaten.no using an electronic ID such as BankID. Submissions and feedback also appear in your Altinn inbox.
