For business trips from Freie Universität Berlin to other EU/EEA countries, Switzerland, or the United Kingdom, an A1 certificate is always required, regardless of how short the trip is (even for one day), as it proves that German social security law continues to apply and that no social security contributions need to be paid abroad. Employees and civil servants must apply for this document from their health insurance fund or pension insurance fund and carry it with them during their trip.

When you need an A1 certificate:

• Travel within the EU/EEA: (e.g., to France, Italy, Spain).
• Travel to Switzerland.
• Travel to the United Kingdom (UK).
• Regardless of the duration: even for one-day trips.

What the A1 certificate does:

• It confirms that you are still subject to the German social security system.
• It ensures that you do not have to pay social security contributions in the country where you are temporarily staying.

What you need to do:

• This information sheet on the A1 certificate for business trips provides clear instructions on how to apply for the A1 certificate. There is a separate application procedure for salaried employees and civil servants.
