Voluntary NI from abroad: Class 2 vs Class 3

For years, Brits abroad could buy a year of State Pension for the price of a few takeaways. From 6 April 2026 that bargain has gone, and the rules for who can pay at all are much tighter.

The short version

From 6 April 2026 you can no longer pay voluntary Class 2 contributions for time abroad, with narrow exceptions [1][2].
Class 3 is now the only route for most people. It costs £18.40 a week in 2026/27, about £957 for a full year [3].
New applicants from 6 April 2026 must have lived in the UK for 10 continuous years or have 10 qualifying years. It used to be three [1].
If you were already paying Class 3 from abroad, you carry on. If you were paying Class 2, you had a window to switch to Class 3 under the old three-year test, and the last date to apply is 5 April 2027 [1][2].
First-time applicants use form CF83, online or by post [2].

What changed on 6 April 2026

HMRC set out the changes in a policy paper in March 2026, announced at Budget 2025 [1]. There are two:

Voluntary Class 2 for periods abroad was abolished. Class 2 was the cheap option for people who worked before they left. Most employed and self-employed people abroad can't pay it for 2026/27 onwards. HMRC expected about 46,000 people to be affected [1].
The residence or contribution test for Class 3 went from three years to ten. To pay Class 3 from abroad as a new applicant, you must have lived in the UK for at least 10 continuous years, or have at least 10 qualifying years on your record [1]. Voluntary contributions you've paid while abroad don't count towards those 10 years, except those under a social security agreement or as a volunteer development worker [1].

Periods before 6 April 2026 aren't affected. If you're filling gaps for 2025/26 or earlier, the old rules for those years still apply [1].

Who can still pay Class 2

Only two groups [1]:

self-employed people treated as self-employed in the UK under a social security agreement
volunteer development workers, who pay a special Class 2 rate (£6.45 a week in 2026/27)

Class 2 vs Class 3 at a glance

	Class 2 (voluntary, abroad)	Class 3 (voluntary)
Weekly rate 2026/27	£3.65 (only for the exceptions above)	£18.40
Cost of a full year	about £190	about £957
Available for time abroad from 6 April 2026	No, with narrow exceptions	Yes, if you meet the conditions
Counts towards State Pension	Yes	Yes

Rates from GOV.UK for 2026/27 [3]. HMRC's own sum: Class 3 costs £767 a year more than Class 2 at 2026/27 rates [1].

Who can pay Class 3 from abroad now

There are three groups, and which one you're in depends on what you were doing before April 2026.

1. You were already paying Class 3 from abroad. You can carry on without reapplying and without meeting the 10-year test [1].

2. You were paying voluntary Class 2 from abroad. HMRC wrote to this group in July 2026. You can switch to Class 3 under the old three-year test if all of these apply [2]:

you applied to pay voluntary Class 2 or Class 3 for 2024/25 or 2025/26 on or before 5 April 2026
you pay the contributions you applied for on or before 5 April 2027
you apply to pay Class 3 for 2026/27 on or before 5 April 2027

HMRC has an online form for this group, and you should only use it if HMRC has written to you [2]. Once you move back to live or work in the UK, the transitional rules stop applying.

3. Everyone else applying from 6 April 2026. You need 10 continuous years living in the UK, or 10 qualifying years on your National Insurance record, before you can pay Class 3 for time abroad [1]. If you left the UK young, after a few years' work, this may rule you out.

Is it still worth it?

Usually, yes, if you'll be short of 35 qualifying years. One full year of Class 3 in 2026/27 costs about £957. Each qualifying year adds roughly 1/35 of the full new State Pension, which is £241.30 a week in 2026/27 [4]. That's about £6.89 a week, or around £358 a year, for life. You'd get your money back in under three years of drawing your pension.

Before paying, watch for these:

You may not need it. If you'll already have 35 years, or more for some people with contracted-out years, extra years add nothing.
Frozen pensions. If you'll retire somewhere the State Pension is frozen, the extra amount is frozen too. Our guide to the State Pension abroad lists where it rises.
Not every year is equal. Some years with partial contributions can be completed for less, and some years may not improve your pension at all. The forecast and HMRC will tell you.

How to apply and pay from abroad

Check your State Pension forecast and National Insurance record on GOV.UK. It shows which years are incomplete and whether paying for them would help.
First time, or after a break? Fill in form CF83 [2]. You can apply online or print and post it. Have your National Insurance number, dates of living and working in the UK and abroad, and your UK and overseas addresses ready.
Already paying Class 2 and HMRC wrote to you? Use the special online form, not the CF83, and meet the 5 April 2027 deadlines [2].
Wait for HMRC's reply. It confirms what you can pay, how much and the reference to use.
Pay the way HMRC's letter sets out, and use the exact reference it gives you, or the money can sit unallocated for months.
Check your record a few months later to make sure the years show as full.

HMRC's processing can be slow, so don't leave it until March before a deadline. A proper cuppa and a bit of patience help.

How far back can you go?

Normally you can only pay voluntary contributions for the past six tax years, with a deadline of 5 April each year [5]. For example, you have until 5 April 2032 to fill a gap in 2025/26 [5]. As of November 2026, the oldest year you can still fill under the six-year rule is 2020/21, and its deadline is 5 April 2027.

The rate depends on the year [3]:

if you pay Class 3 for one of the previous two tax years, you pay the rate for that year
for earlier years, you pay the current 2026/27 rate

The 2006 to 2016 window has closed

You may have read about filling gaps all the way back to 2006. That was a one-off concession for men born after 5 April 1951 and women born after 5 April 1953, covering gaps from April 2006 to April 2017. Its deadline was 5 April 2025, and it has passed [6]. Ignore any old article or forum post that says otherwise.

If you're unsure which years are worth buying, the Future Pension Centre and HMRC can help, and our community groups for Brits abroad are a good place to compare notes with people who've done it. Join us here.
