From January 1st 2019, a declaration is required for every self-employed worker who comes to Belgium to pursue a temporal or partial self-employed activity in a high risk sector (construction, meat processing industry and cleaning industry), if that worker neither resides permanently nor is settled in Belgium.

The new version of the L1 document reflects the changes which were made at the end of 2017 to the mandatory Limosa declaration within the scope of the Plans for a fair competition of the State Secretary for the fight against fraud, more particularly as regards the temporary employment and the obligation to mention the economic sector.

Welcome to Working in Belgium

Are you a foreign employer, or their agent, wishing to post one or more workers to Belgium on a temporary basis? Are you a foreign employer, or their agent, of workers working part-time in Belgium?

Are you a self-employed person established in another country, coming to provide services in Belgium on a temporary or part-time basis?

If so, you need to declare your presence as a self-employed person or that of your workers before they begin to work in Belgium.
