If you are sending an employee to work in Belgium, an A1 registration through virk.dk may not always be sufficient. Depending on the nature and duration of the work and who the work is performed for, it may also be necessary to submit a notification under the EU’s Posting of Workers Directive (PWD).
When is PWD registration required in Belgium?
You may be required to submit a PWD registration if your employee is, for example, performing work for a Belgian company, thereby creating value in Belgium.
This may also apply for stays exceeding 90 days for employees from non-EU/EEA/Schengen countries or for the temporary provision of services as a self-employed individual.
In all cases, registration must be completed before the work begins.
