Note: Parts of this manual are under review following Brexit and the current content of this page applies to periods before 1 January 2021.
An exception to the general rule concerns posted workers. A worker may remain liable for Class 1 NICs if:
they are employed in the UK ; and
are posted by that employer to work in another RA country ; and
the posting is for a period not exceeding the maximum posting period allowed by the terms of the RA (the maximum period of posting will depend on the RA)
