A new agreement between the Isle of Man and United Kingdom is set to modernise National Insurance rules and clarify where people working in either jurisdiction pay their contributions.
Replacing arrangements dating back to 1977, the 2026 agreement establishes that, in most cases, National Insurance is paid in the jurisdiction where the work takes place, ending uncertainty for workers and employers.
In addition, it will grant the Isle of Man greater independence over its National Insurance policy, freeing it from the requirement to mirror UK arrangements.
Treasury Minister Chris Thomas MHK said:
‘This new agreement marks an important milestone, providing much-needed clarity for workers and employers operating between the Isle of Man and the United Kingdom. By modernising arrangements, we are ensuring they reflect the realities of today’s workforce while supporting greater independence in how we shape our own National Insurance policy.’
He added:
‘I would like to thank our colleagues in the UK Government for their constructive engagement and collaboration throughout this process, which has been essential in reaching this positive outcome.’
The Treasury Minister has exchanged letters with the UK, and the Social Security (National Insurance Contributions Reciprocal Agreement) (United Kingdom) Order 2026 is included on the Tynwald Register of Business for June. If approved by Tynwald, and ratified by the UK, the agreement will come into force on 6 April 2027.
