Approach and documents

What steps to take to affiliate your company to the Overseas Social Security service? How should you affiliate employees? What documents need to be provided? For more information, please consult the page Collective affiliation: approach and documents.

When is your staff protected by the Overseas Social Security?

Your employees are insured:

  • while they work in a country outside the EEA, Switzerland or the United Kingdom, and
  • while they are temporarily (no more than 6 months) seconded from their overseas post with an A1 certificate of Coverage (page in French)(New window) to an EEA country, Switzerland or the United Kingdom, and
  • during their contractual leave immediately following the periods mentioned above, and
  • during a period of no more than 12 months immediately following one of these periods, to the extent that they did not exercise any other gainful activity. Please note that receiving unemployment benefit is considered a gainful activity.

You can insure yourself retroactively by paying a so-called 'instant premium'. This way you cover periods in the past for which your employees where not affiliated to the Overseas Social Security, but still met the conditions. Your employees can also choose to pay the contributions themselves.
