Voluntary National Insurance from abroad: the 5 April 2027 deadline
The short version: if you live abroad with gaps in your UK National Insurance record, three things change on 5 April 2027. 2020–21 closes for good. If you applied before 6 April 2026, you must pay 2024–25 or 2025–26 by then to keep the easier 3-year test for later years, and former Class 2 payers must also apply for 2026–27 Class 3. Then prices rise. In our first example waiting costs 2020–21 and £47 more for the rest.
What changes, and who it affects
- 2020–21 can’t be paid after 5 April 2027. Each tax year is open for six years. Anyone with a gap in 2020–21 must pay it (or have HMRC accept the application) by then.
- The transitional rule ends for anyone who doesn’t act. Since 6 April 2026, new applicants abroad need 10 years in a row living in the UK or 10 years of UK-paid contributions to pay Class 3. If you applied to pay for 2024–25 or 2025–26 before 6 April 2026, you keep the old 3-year test only if you pay that year by 5 April 2027. Former Class 2 payers must also apply for 2026–27 Class 3 by the same date (The Social Security (Contributions) (Amendment No. 2) Regulations 2026, SI 2026/294).
- Prices rise on 6 April 2027: Class 3 from £18.40 to £19.05 a week, Class 2 from £3.65 to £3.80 (announced at Budget 2026; the regulations are due early in 2027).
What waiting costs: three examples
| Person | Pay by 5 April 2027 | Adds a year, for life | If they wait |
|---|---|---|---|
| 12 years in the UK, worked there before leaving and works abroad; 22 years on record, gaps 2020–21 to 2026–27 | £2,088 | £2,510 | Loses 2020–21; the rest cost £47 more |
| 5 years in the UK, already paying Class 3 (applied before 6 April 2026); gaps 2020–21, 2024–25 to 2026–27 | £3,744 | £1,434 | Loses 2020–21 and 2026–27: 2026–27 then needs the 10-year test |
| 6 years in the UK, was paying Class 2 (applied before 6 April 2026); gaps 2024–25 to 2026–27 | £1,329 | £1,075 | Loses 2026–27 unless they pay a protected year and apply for Class 3 in time |
Cost at 2026–27 rates (original, lower rates for recent years); waiting uses the announced 2027–28 rates. Pension gain at 1/35 of £241.30 a week per year; people with years before 2016 should check their forecast.
What to do before 5 April 2027
- Check your National Insurance record on gov.uk and note every gap from 2020–21 onwards.
- Check your State Pension forecast: it shows whether extra years raise your pension (some pre-2016 records gain less).
- Work out which years to buy and the class with the voluntary NI from abroad calculator. It lists only the 5 April 2027 items that apply to you, gives you a calendar file with every deadline, and shows what the country you live in does to the extra pension.
- Apply with form CF83 now: HMRC’s letter with your payment reference can take 8 weeks or more from abroad. Former Class 2 payers: apply for 2026–27 Class 3 in the same go.
- Do not pay until HMRC writes with the amount and a payment reference, then pay 2020–21 and the protected year first, before 5 April 2027.
Frequently asked questions
What is the 5 April 2027 deadline for voluntary National Insurance?
Three things happen. 2020–21 can no longer be paid after 5 April 2027 (each year must be paid within six years). People who applied to pay for 2024–25 or 2025–26 before 6 April 2026 keep the old 3-year test for 2026–27 only if they pay that year by 5 April 2027, and former Class 2 payers must also apply for 2026–27 Class 3 by then. And on 6 April 2027 the rates rise to £19.05 a week for Class 3 and £3.80 for Class 2, as announced at Budget 2026.
Is it worth paying voluntary NI from abroad?
Usually, if you will have between 10 and 35 qualifying years. Each year adds 1/35 of the full new State Pension, about £359 a year for life, and costs £956.80 as Class 3 or £189.80 as Class 2 in 2026–27: paid back in under three years of pension, or under a year for Class 2. Check your State Pension forecast first: some people with years before 2016 gain less.
Can I still pay Class 2 from abroad?
For tax years up to 2025–26, yes, if you worked in the UK immediately before leaving and work while abroad. From 2026–27 Class 2 is no longer available for time abroad; only Class 3.
What is the 10-year test?
For 2026–27 onwards, new applicants abroad need 10 years in a row living in the UK or 10 years of UK-paid contributions to pay Class 3 (credits and voluntary years paid from abroad do not count). People protected by the transitional rule keep the old 3-year test while they live abroad.
How long does HMRC take to accept an application?
Records can take 8 weeks or more to update from abroad, and you must wait for HMRC’s letter with your payment reference before paying. Apply with form CF83 well before 5 April 2027. Within 6 months of State Pension age you contact the International Pension Centre instead.
