Expat Tax Residency in Norway

Norway's tax residency rules are administered by Skatteetaten (the Norwegian Tax Administration) and rest on two straightforward physical-presence tests. Understanding these tests — and the obligations that attach once residency is established — is essential for any foreign national considering a period of work or living in Norway.

How does Norway determine tax residency for foreign nationals?

Under Norwegian tax law, two separate presence thresholds can trigger full (unlimited) tax liability on worldwide income. The 183-day test applies when a foreign national is physically present in Norway for more than 183 days within any rolling 12-month period. The 270-day test operates over a longer window: presence exceeding 270 days during any 36-month period establishes residency regardless of whether the 183-day threshold was crossed in a single year. Both part-days and full days count toward either total, meaning even a brief visit on day of arrival or departure is included in the calculation [1].

The date residency takes effect depends on timing. If you accumulate more than 183 days during the same calendar year you first arrive, Norwegian tax residency runs from your first day in Norway for that year. If the 183 days straddle two consecutive calendar years, residency commences on 1 January of the second year. Under the 270-day rule, residency begins on 1 January of the year in which cumulative presence crosses 270 days [1].

What income is taxed once you become a Norwegian resident?

Once tax residency is established, Norway taxes residents on their worldwide income and wealth -- salary earned abroad, foreign rental income, overseas capital gains, and foreign investment returns all fall within scope [2]. The rate structure has two components.

Ordinary income (alminnelig inntekt) is taxed at a flat 22% after standard deductions. On top of this, personal income (gross earned income before deductions) is subject to a progressive bracket tax (trinnskatt) and a national insurance contribution (trygdeavgift) of 7.6% on wages (2025). The combined marginal rate at the highest band reaches approximately 47.4% [3].

Norway also levies a wealth tax (formuesskatt) on net assets. For 2025, the combined municipal and state rate is 1.0% on taxable net wealth above NOK 1,900,000, rising to 1.1% on wealth above NOK 21,500,000 [4]. Residents holding substantial assets overseas must include those in the Norwegian wealth calculation.

What are the 2025 income tax rates and thresholds?

The table below sets out the 2025 bracket tax (trinnskatt) bands alongside ordinary income tax and national insurance contribution, based on figures published by Skatteetaten [3].

Bracket tax is added to the flat 22% ordinary income rate and the 7.6% national insurance contribution on wages, producing a combined marginal rate above approximately 47.4% for high earners.

What is the PAYE scheme for foreign workers?

Skatteetaten operates a simplified tax regime known as PAYE (Pay As You Earn) specifically for foreign workers during short stays and the first year of tax residency in Norway. Under PAYE, the employer deducts a flat 25% tax on gross salary -- this single rate covers both income tax and national insurance contributions, making the arrangement self-contained [5]. Workers with salary income up to NOK 697,150 in 2025 are eligible; earnings above that ceiling disqualify the worker from the scheme for that income year.

PAYE is the default for most new foreign workers and automatically applies unless the worker opts out. Key features: no deductions are permitted against the gross salary, no tax return is required, and no annual tax assessment notice is issued. Workers exempt from Norwegian national insurance (for example, because they hold an A1 portable-document certificate from another EEA country) pay a reduced rate of 17.4% instead. Workers can choose to leave the PAYE scheme voluntarily by electing general taxation rules before the relevant income year closes [5].

How does Norway's exit tax work on emigration?

Leaving Norway does not end tax obligations immediately. The utflyttingsskatt (exit tax) applies when tax residency ceases and a person holds shares or ownership interests in companies with unrealized capital gains. For departures after 20 November 2024, Skatteetaten grants a base deduction of NOK 3,000,000 against the computed latent gain; gains exceeding that amount are subject to tax as though the shares had been sold on the day before emigration. The applicable rate is approximately 37.84% on the net gain above the NOK 3 million deduction [6].

Payment can be deferred for up to 12 years from the date of departure -- or until the shares are actually sold, whichever comes first. Deferral requires annual reporting to Skatteetaten on the underlying holdings. Individuals who return to Norwegian tax residency before 12 years elapse may have the exit tax reassessed. The relevant declaration form is RF-1141 [6].

How does tax residency end when leaving Norway?

Ceasing Norwegian tax residency requires meeting three cumulative conditions, verified annually by Skatteetaten: (1) establishing a permanent residence abroad; (2) spending fewer than 62 days in Norway during the income year; and (3) having no housing available to you or a close relative in Norway [1].

For those who have been Norwegian tax residents for 10 years or more before departure, stricter rules apply. These long-term residents remain Norwegian tax residents through the third full tax year after the year they leave -- the three-year tail -- unless the three cessation conditions are demonstrably met in each of those years. Until all conditions are satisfied for three consecutive years, worldwide income continues to be taxed in Norway [1].

What are a D-number and a tax deduction card?

Every foreign national working in Norway needs two documents before the first payslip. A D-number is a temporary national identification number issued to persons who are not registered in the Norwegian Population Register but have a legal obligation or right to obtain one. It is required for all tax purposes in Norway. A tax deduction card (skattetrekkskort) tells the employer what rate to withhold; for PAYE workers, the card will reflect the 25% flat rate. Both are obtained through Skatteetaten using form RF-1209, supported by an in-person identity verification or certified copy of an identity document [7]. Employers can also apply for the tax card on behalf of an employee. Without a valid tax deduction card on file, employers are required by default to withhold 50% of salary.
