Leaving the UK

Can I still pay voluntary National Insurance from abroad now Class 2 has gone, and what is the CF83 deadline?

Answered by Jordan Onraet-Wells, Founder & Chartered Tax Adviser (CTA). Published 17 August 2026. Last reviewed 17 August 2026.

The short answer

Yes, you can still pay voluntary National Insurance from abroad, but from 6 April 2026 the cheap Class 2 route is abolished for periods overseas and most people can only pay Class 3, which costs £18.40 a week (£956.80 a year) against £3.65 a week for Class 2. New applicants from 2026/27 must also have either 10 continuous years of UK residence or 10 years of paid qualifying contributions, up from 3 under the old test. The transitional deadlines all fall in April 2027: existing Class 2 payers can switch to Class 3 without meeting the new 10 year test if they apply before 6 April 2027, and CF83 applications made on or before 5 April 2026 keep the old rules provided the contributions are paid on or before 5 April 2027.

Voluntary Class 2 for time abroad was abolished from 6 April 2026; for 2026/27 onwards Class 3 is the only route for most people overseas, with narrow exceptions for certain social security agreement cases and volunteer development workers.
At 2026/27 rates Class 3 costs £18.40 a week (£956.80 a year) against £3.65 a week (£189.80 a year) for Class 2, a difference HMRC's policy paper puts at £767 a year.
New overseas applicants now need 10 continuous years of UK residence or 10 years of paid qualifying contributions; National Insurance credits do not count, and the old test was 3 years.
Existing Class 2 payers abroad can apply to pay Class 3 under the old, more generous criteria if the application goes in before 6 April 2027; CF83 applications made on or before 5 April 2026 for 2024/25 or 2025/26 keep the previous rules if paid by 5 April 2027.
Even at the Class 3 price the maths usually works: one extra qualifying year typically adds roughly £358 a year to the new State Pension, so a £956.80 year is normally recovered within about three years of retirement.

What changed in April 2026

An HMRC policy paper published on 16 March 2026 confirmed that voluntary Class 2 National Insurance is abolished for periods abroad from the 2026/27 tax year, and HMRC is writing to the roughly 46,000 people who were paying Class 2 from overseas. From the same date, new applications to pay Class 3 for time abroad face a much tougher entry test: 10 years of continuous UK residence or 10 years of paid qualifying contributions, where credits do not count. People already paying Class 3 from abroad are unaffected and simply carry on. The full detail, including who keeps access to special Class 2 rates, is in our guide to voluntary NI from abroad after the Class 2 change.

The April 2027 deadlines, group by group

Which deadline applies depends on where you already stand. If you were paying Class 2 from abroad, your liability closed with 2025/26 and you can apply to move to Class 3 without meeting the new 10 year test, as long as your application is submitted before 6 April 2027; you can also still sweep up pre 6 April 2026 gaps at Class 2 rates if you met the old conditions, subject to the normal time limits. If your CF83 was already in the pipeline, applications made on or before 5 April 2026 for 2024/25 or 2025/26 are assessed under the previous rules, including the old 3 year test, provided the contributions are paid on or before 5 April 2027; an application to cover 2026/27 must also go in by 5 April 2027. What counts is the date the application is submitted, not the date HMRC processes it, so apply early and keep evidence. Note HMRC cannot process a CF83 at all if you are over State Pension age or within 6 months of it.

Is Class 3 still worth paying?

For most expats, yes. The full new State Pension is £241.30 a week in 2026/27 and normally needs 35 qualifying years, so one extra year is typically worth about £358 a year for life, which repays a £956.80 Class 3 year in under three years of retirement. Check your State Pension forecast first, because extra years add nothing once you are on course for the full amount, contracted out records before 2016 do not always gain pound for pound, and annual increases stop in some countries, including Australia and Canada. You can usually fill gaps for the previous 6 tax years, and older gaps are charged at current rates once outside the original rate window, so identified gaps should not sit unpaid. Your NI record is one strand of a clean UK exit alongside your departure paperwork and leaving year refund and any ongoing expat Self Assessment.
