Brexit and Social Security

Brexit is an ongoing rollercoaster for employers and their employees. A lot has changed and has been clarified over the past few months, particularly with respect to internationally mobile employees and their social security.

For existing situations, the Withdrawal Agreement secured the continued protection of social security rights and free movement until 31 December 2020. This also applies to cross-border situations which are not interrupted.

For new cross-border situations with the UK, a Trade and Cooperation Agreement has been concluded. The protocol on social security includes principles which may seem similar to the EU regulations but do contain important differences. There are still a lot of question marks and as long as these are not settled on a central level, many countries may have their own interpretation of the provisions in the protocol.
