What every posting employer and (Belgian) service user should know about the Limosa notification.

A foreign employer posting workers to Belgium must file a Limosa with the Belgian Social Security Office prior to the activities in Belgium starting.

The service user must verify whether a Limosa has been made. If the posting employer cannot prove that Limosa has been filed, then the service user must notify the posted worker's presence to the Belgian Social Security Office.

What happens if I have not filed a Limosa?

Non-compliance with the Limosa notification & verification obligation can trigger very significant administrative and/or criminal penalties for the posting employer and/or the service user.

Limosa verification. As a service user you can verify whether the information stated on the Limosa-1 is in line with the information that the posting employer has filed electronically. This verification step is not mandatory.
