From HM Revenue & Customs · National Insurance Manual
Note: This page is under review and the content may only be appropriate to periods beginning before 1 January 2021 and for those covered by a Withdrawal Agreement. A new International NICs manual is under development and will be published in due course.
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)
Some Reciprocal Agreements contain articles for working in both territories for the same period. In these circumstances, liability is normally in the territory where the employee is ordinarily resident.
The employer can obtain a certificate of continuing liability (COC), similar to Portable Document A1, see GOV.UK to prevent a demand for payment of contributions in the RA country. Extensions of the posting periods can be obtained with agreement with the foreign authority similar to EC rules - see NIM33020.
