This article examines how Brexit will impact social security for internationally mobile employees and their employers.

Within the article, our expert takes a closer look at the key details for internationally mobile employees between the UK and the EU, which will become more complicated following the end of the transition period on 31 December 2020.

This is an extract from Tax Journal, first published on October 23, 2020. The whole publication is available at:

“The Withdrawal Agreement provides that existing arrangements for employees internationally mobile at 31 December are capable of continuing unchanged ‘for as long as they continue without interruption’. However, the position is different for employees who become internationally mobile from 1 January 2021. The UK has agreed a reciprocal agreement with Ireland which broadly provides for the same outcomes as under the current EU regulations. But for employees internationally mobile between the UK and other EU member states, EEA members and Switzerland, the position is not yet finalised and will depend on the outcome of any final deal reached between the UK and the EU.

Up to, and including, 31 December 2020, the social security coverage of internationally mobile employees working between the UK and EU is covered by the EU social security regulations (Regulation (EC) No. 883/2004 and 987/2009), ensuring that individuals are only liable to pay contributions in a single member state, and which provide clear (if complex) rules for determining in which state that is, under a multitude of different circumstances.”
