While measures to limit the spread of the COVID-19 corona virus are in force, the Overseas Social Security has adjusted its services. These are the measures we have taken to be of assistance to you.

COVID 19 – PCR test for travelling

As far as travelling is concerned, our Office will only reimburse PCR tests that have been taken for the return trip. Tests realized in Belgium will be reimbursed on the basis of the RIZIV/INAMI-scale. For tests taken outside Belgium, reimbursement will be made up to 75%.

Can you get a COVID-19 vaccination in Belgium?

Are you a resident in Belgium?

The Belgian vaccination strategy determines that all persons having a Belgian residency can be vaccinated. As a resident in Belgium, you will receive an invitation from the authorities to get vaccinated in a vaccination centre closest to your place of residence. This vaccination is free of charge.

Are you not a resident in Belgium?

Normally the COVID-19 vaccination is free of charge in all countries. In case you would however be charged and are affiliated to the Overseas Social Security with a supplementary Medical care insurance, you can get a reimbursement of up to 75% of the vaccination costs.

In case you are affiliated to the Overseas Social Security and are entitled to the deferred healthcare insurance, you cannot benefit from any reimbursement, since this has (not yet) been provided for by the compulsory Belgian health insurance.

If you have not joined the Overseas Social Security, please check what vaccination strategy applies in your country of residence or join the Overseas Social Security.


In case you have any questions, please consult the contactpage on this website to learn how to reach us.

We have organized our reception areas in such a way that good hygiene and sufficient distance are guaranteed.

Are you encountering difficulties to pay your contributions?

Are you encountering difficulties to pay your contributions (general scheme or complementary insurances) due to the socio-economic fallout of the corona crisis?

Whether as an employer or as a private individual, you may ask to postpone payment of your contributions. The deadline of this postponement as stipulated in our regulations is 6 months after the month to which the contribution applies. You do not have to pay interest for delay.

In order to make use of this possibility, proceed as follows:

Do you participate as a private individual, and do you wish to suspend your participation temporarily? That is possible. Please make your request by sending an email to overseas@onss.fgov.be.

Once the crisis is over, you simply pick up your participation again. There will be no waiting time for healthcare, even if the suspension lasted for more than 2 months. You must, however, renew your participation within 3 months of the end of the isolation in your country of activity due to Covid-19. All you have to do is make your request to the email address mentioned below.

Our employees will answer your questions and advise you about the best possible solution in your individual situation. Please contact the ‘Client Contact’ service by writing to the following address: overseas@onss.fgov.be.

Temporary unemployment

The Overseas Social Security does not comprise an unemployment branch.

Do you normally work outside of the European Economic Area (EEA), but are you now in Belgium, unable to return to your foreign posting? Then you may make use of the system of temporary unemployment through force majeure as a result of the corona crisis. To make that possible, your employer must temporarily suspend your participation in the Overseas Social Security and reattach you to the Belgian firm.

For more information, please consult the FAQ in the COVID-19 Information section on the homepage of the National Employment Office website (in French)(New window).
