You are going to work in another country temporarily

If you are going to work in another country temporarily, you can remain  insured under the social insurance system of the country where you live and work as a self-employed person. This situation is called a posting, and there are specific rules for it. There may also be additional rules if you hire in workers or if you have a construction company. 

For more information, select the situation that applies to you.

If you work temporarily in Belgium as a posted worker, you will remain insured under the Dutch social insurance system for the temporary period you work in Belgium.

  • you were covered by Dutch social insurance for the period leading up to your posting
  • you have the nationality of a country in the European Union (EU ) or European Economic Area (EEA )
  • the posting period is not longer than 24 months

If you hire workers in from a Dutch company, check first to see if that company is also registered with the KVK.
