Declaring a professional activity abroad

Last update

Employers who intend to send their employees to work outside Luxembourg must declare this activity to the Joint Social Security Centre (CCSS).

From 2 April 2024, new procedures for declaring a professional activity abroad will be introduced.

These changes apply to employers who use:

  • paper forms;
  • the SECUline system.

New paper forms, specifically adapted to each type of situation, will be made available.

The file format used for the SECUline procedure will change from DTA to XML and their structure will be adapted.

For more information, you can consult the information pages on professional activities carried out abroad on the CCSS website.
