HM Treasury has made the Social Security (Contributions) (Amendment No. 2) Regulations 2026, coming into force on 6 April 2026 for the 2026–27 tax year onwards. The instrument closes the voluntary Class 2 National Insurance route for periods spent abroad and sets a new Class 3‑only framework for those outside the UK. GOV.UK guidance confirms the 6 April 2026 start date and that time abroad before that date is unaffected. (gov.uk)
The change is implemented by amending regulation 147 of the Social Security (Contributions) Regulations 2001. Paragraphs (1) and (2) are omitted and a new paragraph (5) is inserted so that, from 2026–27, an individual outside the UK may pay Class 3 if they satisfy existing paragraph (3) conditions and either fall within transitional cohorts or meet a new connection test. Regulation 146(2)(a) remains an exclusion. (legislation.gov.uk)
For individuals who paid voluntary Class 2 under regulation 147 in 2024–25 or 2025–26, the Regulations allow payment of Class 3 for 2026–27 and later years on the same basis that previously applied, provided HMRC has been notified. Notification of Class 2 entitlement must be made by 6 April 2026 and notification of entitlement to pay Class 3 under the revised regulation 147(5)(a) must be made before the earlier of the payment date or 6 April 2027, as specified in the instrument.
For individuals who paid voluntary Class 3 under regulation 147 in 2024–25 or 2025–26, continuation into 2026–27 under regulation 147(5)(a) is available if HMRC was notified of that prior Class 3 entitlement by 6 April 2026. Separately, Class 3 payments for years ending before 6 April 2026 may still be made after that date, subject to existing HMRC time limits confirmed in official guidance. (gov.uk)
Payments under regulation 147(5)(a) cannot be made after the ‘relevant date’ set under regulation 87AA(3)(b) where a person has notified HMRC that they wish to cease, nor once the person becomes entitled to pay Class 3 pursuant to regulation 145(1)(e) for a post‑5 April 2026 year. These cut‑offs prevent overlap between notification‑based entitlements in the 2001 Regulations. (assets.publishing.service.gov.uk)
For new applicants from 2026–27 who did not previously pay under regulation 147, the Regulations introduce a higher‑bar UK link. An individual outside the UK may pay Class 3 only if they have either a continuous period of at least 10 years’ residence in Great Britain or Northern Ireland at any time before payment, or 10 tax years in which qualifying contributions were paid under specified ‘payments abroad’, ‘residence and presence’, or ‘volunteer development worker’ regulations. GOV.UK summarises the 10‑year requirement. (gov.uk)
‘Qualifying contributions’ follow existing law: a year counts if the earnings factor is at least 52 times the lower earnings limit for that year or if 52 contributions were paid under earlier Social Security Acts. The cross‑references to the 1948, 1975 and 1979 regulations are preserved to maintain historic credits under the 2001 Regulations. (legislation.gov.uk)
The application and notification framework remains anchored in regulations 87, 87A and 87AA of the 2001 Regulations. In practice, applicants use HMRC form CF83 to apply from abroad and should ensure any required notifications are made before the relevant dates set out above. (legislation.gov.uk)
In practical terms, most overseas contributors move from the lower‑cost Class 2 rate to the higher Class 3 rate from 6 April 2026. HMRC guidance confirms the policy change and illustrates current voluntary contribution rates, underscoring the cost impact of switching to Class 3 for future qualifying years. (gov.uk)
HMRC indicates it will contact affected payers from July 2026. The Departments responsible in Great Britain and Northern Ireland concurred in making the Regulations, aligning treatment under both the 1992 Acts and ensuring consistency across the UK social security system. (gov.uk)
