Not resident in Norway: Even if you do not live in Norway, you have a compulsory membership in the National Insurance Scheme if you for example
Voluntary membership during stays in Norway: If you will be staying in Norway between 3 and 12 months, will not be working and have strong ties to Norway, you may be entitled to a voluntary membership (text in Norwegian only) in the National Insurance Scheme.
Voluntary membership during stays outside of Norway: If you have a compulsory membership in the National Insurance Scheme and will be staying abroad, the stay abroad may mean that your membership in the National Insurance Scheme ends. If the compulsory membership ends, you should find out whether you are entitled to a voluntary membership (text in Norwegian only) in the National Insurance Scheme during your stay abroad.
If you are working in or moving to a country with which Norway has a social security agreement, you must find out what your rights are under the individual agreement in question. The provisions of this agreement take precedence over Norwegian law.
Social security agreements regulate your social security membership, specifically which country that will be providing you with coverage. You will have the same rights and obligations as do nationals of the country where you are staying. Individuals from agreement countries are treated equally, regardless of nationality.
As a rule, you will only be covered by social security in one country, and, consequently, you do not have to pay social security contributions to both countries.
Social security agreements also make it possible for workers who are temporarily posted to another agreement country for work to retain their membership in Norwegian National Insurance.
Norway has social security agreements with a number of countries.
Norway has also established bilateral agreements with the United States, Canada, Australia and India.
Membership in the National Insurance scheme means that you have to pay a national insurance contribution if you have an income from a pension or from work,
The amount you must pay depends on
whether you pay tax to Norway and on whether the Norwegian Tax Administration collects the national insurance contribution together with your taxes
Work or long-term stays abroad can end your membership in the National Insurance Scheme.
If you are not a member of the National Insurance Scheme, you have no rights pursuant to the National Insurance Act. This also means that you do not pay a national insurance contribution.
