Many individuals relocating abroad assume that their Norwegian tax liability ends on the day they submit a notification of departure to the Norwegian National Population Register. In practice, this is one of the most common misconceptions associated with leaving Norway.
Under the Norwegian Tax Act, specific rules determine when an individual ceases to be tax resident in Norway. These rules are technical, and for individuals who have lived in Norway for a long period, it may take several years before their ordinary Norwegian tax liability actually comes to an end.
What does it mean to be tax resident in Norway?
As a general rule, an individual who is tax resident in Norway is subject to Norwegian tax on their worldwide income and wealth, regardless of where the income is earned or where the assets are located. This is known as the principle of worldwide taxation.
Once Norwegian tax residence ceases, the individual's tax liability will generally be limited to income and assets that retain a specific connection with Norway.
Registration does not determine tax residence
A key point is that registration with the Norwegian National Population Register does not determine whether tax residence has ended.
An individual may be registered as having emigrated from Norway while still remaining tax resident under the Norwegian Tax Act. Likewise, a foreign national may be tax resident in Norway despite not being a Norwegian citizen.
Tax residence is determined by the individual's actual connection with Norway and the conditions laid down in Section 2-1 of the Norwegian Tax Act.
Two different sets of rules
The legislation distinguishes between two categories of taxpayers:
- individuals who have been tax resident in Norway for less than ten years; and
- individuals who have been tax resident in Norway for at least ten years.
This distinction is crucial in determining how quickly Norwegian tax residence can come to an end.
Leaving Norway after less than ten years of tax residence
If you have been tax resident in Norway for less than ten years, your Norwegian tax residence may cease during the year of departure, provided that three conditions are met:
- you have established permanent residence abroad;
- you do not spend more than 61 days in Norway during the relevant income year; and
- neither you nor your close relatives have the right to use a dwelling in Norway. Close relatives include a spouse, cohabiting partner, or minor children.
Where all three conditions are satisfied during the same income year, Norwegian tax residence ceases from the time both permanent residence abroad has been established and any right to use a dwelling in Norway has ended.
Have you been tax resident in Norway for at least ten years?
The rules are more stringent for individuals who have been tax resident in Norway for at least ten years.
Even if you move abroad permanently, sell your home, and formally notify the authorities of your departure, you will generally continue to be regarded as tax resident in Norway during the year of departure and the following three income years.
To terminate Norwegian tax residence, you must throughout this entire period be able to demonstrate that:
- you have established permanent residence abroad;
- you do not spend more than 61 days in Norway during each individual income year; and
- neither you nor your close relatives have the right to use a dwelling in Norway.
If any one of these conditions is breached, the three-year period may, in practice, have to begin again.
What is meant by "permanent residence abroad"?
The Norwegian Tax Act does not define this concept in detail. However, the individual must have established genuine and lasting residence outside Norway.
A holiday stay, a short-term work assignment, or a temporary period of study abroad will generally not be sufficient if the individual's personal and economic life remains primarily connected to Norway.
Whether this requirement is satisfied depends on the specific facts and circumstances of each case.
The 61-day rule
Many people are aware that they cannot spend more than 61 days per year in Norway if they wish to terminate Norwegian tax residence. Fewer people understand how these days are calculated.
Every calendar day—or part of a calendar day—spent in Norway counts towards the 61-day limit. It makes no difference why the individual is present in Norway. Holidays, work, illness, family visits, and similar stays are all treated in the same way.
The burden of proving the number of days spent in Norway rests with the taxpayer. If requested by the Norwegian tax authorities, flight itineraries, calendars, travel records, passport stamps, and other objective evidence may therefore become important.
A dwelling in Norway may prevent tax emigration
Another key requirement for terminating Norwegian tax residence is that the taxpayer must not have the right to use a dwelling in Norway.
The decisive factor is not whether the dwelling is actually used. If the taxpayer continues to own, rent, or otherwise retains the legal right to occupy a dwelling, the condition may not be satisfied. The rules also extend to indirect rights of use and dwellings that are available through close relatives.
For this reason, many individuals choose to sell their Norwegian home so that their right to use it genuinely comes to an end.
Tax treaties may produce a different result
In some cases, an individual may be regarded as tax resident in both Norway and their new country of residence under the domestic laws of each country.
In such situations, residence must be determined under the residence provisions of the applicable tax treaty—the so-called tie-breaker rules.
It is important to understand that this does not automatically mean that Norwegian tax residence has ceased under Norwegian domestic law. The primary function of the tax treaty is to determine which country has the right to tax the individual under the treaty. Under Norwegian domestic law, the individual may nevertheless continue to be regarded as tax resident until the statutory conditions for terminating tax residence have been satisfied.
