Norway Tax Residency Calculator 2026 (183-Day Rule)

Tax residency (skattemessig bosted) decides whether Norway taxes all your income and wealth, or only what has a link to Norway. The most common test is the 183-day rule in section 2-1 of the Tax Act (skatteloven). This calculator adds up your stays, checks every 12-month and 36-month period, and shows the day the rule is met and the date from which you are treated as resident. It is useful if you are moving to Norway, working here for part of the year, commuting on rotation or planning to leave.

The two day tests

You are tax resident if you are in Norway for more than 183 days in any 12-month period, or for more than 270 days in any 36-month period. The period is not the calendar year: it can start on any day. The calculator therefore tests the period that ends on every single day you are in Norway. The rule is met on the first day the count passes the limit, that is day number 184 or day number 271. The 270-day test does not apply to people living on Svalbard.

How the days are counted

Every whole or part calendar day in Norway counts, so both the arrival day and the departure day count. Days from separate visits are added together. The test is about physical presence: a Norwegian address, a residence permit or a tax deduction card (skattekort) does not add or remove days, although your ties to Norway can matter under a tax treaty.

When does the rule apply for one long stay?

The table shows a stay of 401 days that begins on different dates in 2026.

If you arrive early enough in the year for the limit to be passed before 31 December, you are resident from your first day. If you arrive later and stay on, the stay spans two income years and you are resident from 1 January of the year in which the limit is passed. That is why arriving in September or November leads to residency from 1 January of the following year.

Worked example

An employee is in Norway from 1 February 2026 to 30 June 2026 and again from 15 August 2026 to 15 October 2026. That is 212 days in total. The limit of 183 days is passed on 17 September 2026, and the person is treated as resident from 1 February 2026. From that date the employee is taxed in Norway on worldwide income, and the salary can be run through the Norway income tax calculator to see the tax and the national insurance contribution (trygdeavgift).

Rotation work and commuting

The table counts every day of the rotation as a day in Norway and assumes the pattern runs for almost three years from March 2026. A 12-month period that contains 29 February has 366 days and can add one day. Any extra travel days between the rotations come on top of these numbers, so commuters should keep a running record of their days.

If you are not tax resident

Non-residents are taxed only on income and property with a link to Norway, for example pay for work done here and income from Norwegian property. Tax treaties between Norway and your home country can limit this, and they can also decide which country counts as your country of residence if both countries treat you as a resident. If you earn a Norwegian salary without being resident, the Norway withholding tax calculator shows how the tax is deducted at source.

Ending residency when you leave

Moving out does not end tax residency by itself. You must have taken up permanent residence abroad, have been in Norway no more than 61 days in the income year, and have no home available in Norway for you, your spouse, your partner or your minor children. After ten or more years as a resident, the conditions must be met for three years. Unrealised gains on shares can be taxed when you leave (exit tax, utflyttingsskatt), with the option to defer or pay in instalments.

What this calculator does not cover

It applies only the day-count rules in section 2-1 of the Tax Act. It does not apply tax treaties, does not judge your ties to another country, and does not assess whether you have ceased to be resident. It does not calculate the tax itself, and it does not cover other day-count rules such as the 90 days in 180 rule for short stays in the Schengen area, which is an immigration rule and unrelated to tax. The result is an estimate and not tax advice.
