Are you already legally employed in a Member State of the European Union or another state party to the Agreement on the European Economic Area (EEA)? Then you do not have to be established as a service provider in Berlin (or Germany) in order to be able to work here too, but can work cross-border under certain conditions.
This can be useful if you intend to:
- Provide the service only temporarily in Berlin
- Provide the service only for a specific customer in Berlin
- Explore the market before expanding your business to Berlin
Whether you need to obtain permits and licences depends on whether you are working in a regulated or non-regulated profession.
