I am self-employed and will carry out an assignment in an EU or EFTA country in a self-employed capacity. Which social security legislation will apply to me?

If you are a Swiss national or EU/EFTA citizen and you have to move temporarily to an EU/EFTA state to carry out an assignment similar to your occupational activities in Switzerland, you usually remain subject to Swiss social security legislation. The assignment must be for no more than 24 months (CH–EU and CH–EFTA posting fact sheets).

Prior to your departure, you must apply for a posting certificate on the ALPS web application (access provided by your OASI office). If the application is approved, the OASI office will issue an A1 certificate.
