Any form of employment in which an employee receives a salary from abroad or in which an employee is seconded to Belgium, must be declared to the Belgian authorities. If you come to work at the University of Antwerp without actually being employed by the university and you still receive a salary from your home university, your employer in your home country must apply for a Limosa declaration.

The purpose of the Limosa declaration is to create a central database of international employees in Belgium and to facilitate the free movement of these foreign workers by means of administrative streamlining.

Who needs to file a LIMOSA declaration?

Limosa is for employees sent to work on a temporary or part-time basis in Belgium. In other words, workers who:

• habitually work in a country other than Belgium;
• were hired in a country other than Belgium.

A declaration is also required for any self-employed person temporarily working in that capacity in Belgium, without residing there on a permanent basis.

On the website of Limosa you can find an overview of staff categories who are exempt from Limosa.

Foreign employers who second salaried employees/researchers to Belgium must provide a declaration via the website of Limosa. A Limosa-1 proof of receipt will immediately be issued. This document may be requested during registration with the Immigration Office in the case of long-term stays in Belgium and must also be sent to your HR Officer in the University of Antwerp’s Human Resources Department.

Which information do they need?

• the personal details of the employee or self-employed person
• the date on which the employee or self-employed person will start and stop working in Belgium
• the place where the employee or self-employed person will actually work in Belgium
• For an employee: the contact details of the foreign employer.
• For an employee: the employee's work schedule

If you have any problems or need advice about the Limosa registration, please contact the International Staff Office.
