Posted workers in the EU/EEA and Switzerland

​You will retain your mandatory membership of the Norwegian National Insurance Scheme if you work for up to two years in another EU/EEA country or Switzerland for your Norwegian employer and are a citizen of Norway, another EU/EEA country or Switzerland.

If you have citizenship of a country outside the EU/EEA and are posted to another Nordic country by an employer in Norway, you will have the same rights as EU/EEA citizens.

If you have citizenship of a country outside the EU/EEA and will be working outside the Nordic region, you should check with NAV whether you will retain membership of the Norwegian National Insurance Scheme during your period of work. If you do retain membership, you may be entitled to benefit for treatment abroad. This means that your expenses relating to certain health services will be covered. We recommend that you also take out private insurance if the amount of benefit you will be entitled to from Helfo is limited.

If you are a posted worker from another Nordic country, you will be entitled to receive healthcare services even if you do not have an S1 certificate.

You can apply for an S1 certificate using a digital form in Altinn. To log in to Altinn you need electronic ID. Click here for information about how to get an electronic ID.

You must attach the following:

• employment contract
• confirmation of the assignment/posting to another EEA country or Switzerland
• certificate A1 from the Norwegian Labour and Welfare Administration (NAV) to prove that you are covered by Norwegian National Insurance legislation – you can find a link to the application for certificate A1 (form NAV 02-08.07) at nav.no

You do not need to attach certificate A1 if you are posted as a government official.

You will find useful information about submitting the digital form here (in Norwegian). 

Paper form

If you are unable to use our digital form, you can fill in and submit the following form instead:

Send your application to: Helfo, P.O. Box 2415, 3104 Tønsberg. 

The certificate will not be valid until Helfo has received feedback from the National Insurance authorities in your country of residence.

Note: Special rules apply if you are working in one of the following countries: Bulgaria, Cyprus, Czech Republic, Estonia, Greece, Hungary, Italy, Latvia, Lithuania, Malta, Poland, Romania, Slovakia, and Slovenia. Find out more about these rules here (in Norwegian).

Because you retain your entitlement to receive healthcare services in Norway, you can choose to travel home to receive treatment, but you will have to cover your travel costs yourself.

If you take dependent family members to the country in which you are going to work with you, they must contact the National Insurance authorities there in order to find out their rights. They may be entitled to their own document confirming their entitlement to receive healthcare services in both the country of work and Norway.

If you opt to receive treatment in the country in which you are working, you will be entitled to receive healthcare services in accordance with the EEA rules. This means your rights will essentially be the same as those who live in the country. You will therefore have to pay the same personal contributions as other inhabitants of the country. Healthcare services that you receive in the country must be provided by the national health service. 

Parents/guardians must also have power of attorney from any children aged 18 or over. In the case of health information, you must have power of attorney from any children aged 16 or over. This is because the age of majority under health law is 16.

Complete the power of attorney form and send it to Helfo as an attachment to a digital form, or send it by post to Helfo, PO Box 2415, 3104 Tønsberg. Remember to enclose a copy of valid identification for the person granting power of attorney.
