NIM16404 | Class 1A National Insurance contributions: Special Class 1A NICs cases: Workers going or coming from abroad who are provided with benefits: Modification of the general liability conditions for NICs
From HM Revenue & Customs · National Insurance Manual
Regulations 145 to 148 of the Social Security (Contributions) Regulations 2001 (SSCR 2001) (SI 2001 No 1004)
NIM16402 and NIM 16403 explain the general conditions that must be satisfied for Class 1A NICs liability to arise on benefits provided to workers who come from abroad to work or who leave the UK to work. They also explain that those conditions can be modified if the worker is from a country
within the European Economic Area (EEA)
which has a Reciprocal Agreement (RA) with the United Kingdom
which has a Double Contribution Convention (DCC) with the United Kingdom
which is neither within the EEA nor with which a RA or DCC is held – referred to as a ‘rest of the world ‘ (ROW) country.
NIM16405 describes the general effect on Class 1A NICs of these agreements, where a benefit is
provided to a worker who has arrived from abroad
provided to a worker whilst they are abroad
left behind for their use when they return
available to a family member while they are abroad.
More detailed information on further variations to these rules is contained in NIM33000.
