Updated 5 August 2026. This guide has been rewritten to reflect the rules that took effect on 6 April 2026. An earlier version described the pre-2026 position, including voluntary Class 2 for time abroad and the 3 year entry test, neither of which now applies.
For most UK nationals living abroad, the UK State Pension sits somewhere between an afterthought and a source of quiet anxiety. You know you spent years paying National Insurance. You are not sure what that entitles you to now. And you have heard, correctly, that the rules for topping up from overseas have just changed.
They have, and the change is not a small one. On 6 April 2026 the cheaper of the two voluntary routes closed for time spent abroad, and the test for the remaining route tightened from three years to ten.
This article sets out the position as it now stands: who can still pay, what it costs, how the CF83 application works, and, most importantly, how to tell whether a year would actually add anything to your pension before you spend money on it.
Two things changed at once, and the second is the one that catches people.
Voluntary Class 2 closed for periods abroad. GOV.UK states, for the 2026 to 2027 tax year onwards: "You cannot pay voluntary Class 2 National Insurance contributions for time abroad."
The entry test rose from 3 years to 10. To pay voluntary Class 3 for time abroad you must now have either "previously lived in the UK for 10 years in a row" or "paid 10 years of qualifying National Insurance contributions in total".
For comparison, the rules that applied for 2025/26 and earlier required either that you had "previously lived in the UK for 3 years in a row" or "paid contributions (or had Class 2 contributions treated as having been paid) for at least 3 years in total". Class 2 additionally required that "you worked in the UK immediately before leaving" and that "you're working abroad (or you worked while you were abroad)".
Because Class 2 has not been abolished as a class. It still exists, and GOV.UK still publishes a rate for it: "The rates for the 2026 to 2027 tax year are: £3.65 a week for Class 2."
What changed is that this route is no longer available for time spent abroad. That distinction is subtle enough that a great deal of otherwise reputable material, and more than one automated summary, still describes expatriates as choosing between Class 2 and Class 3. For periods abroad, that choice no longer exists.
There is a door still open for people who acted before the change.
GOV.UK provides that if you "applied to pay voluntary Class 2 or Class 3 contributions for the 2024 to 2025 or 2025 to 2026 tax year on or before 5 April 2026", you may use the previous rules. Payment must be made "on or before 5 April 2027", and applications for Class 3 contributions for 2026/27 under that route must also be made "on or before 5 April 2027". These arrangements end once you return to live or work in the UK.
If you applied in time, that transitional window is worth diarising rather than assuming it will remain open.
Class 3 voluntary contributions cost £18.40 a week for the 2026 to 2027 tax year, which is £956.80 for a full year.
On the other side of the ledger, the full new State Pension is £241.30 a week, or approximately £12,548 a year. GOV.UK states that "If your National Insurance record started after April 2016 you will need 35 qualifying years to get the full rate of new State Pension."
Where 35 years is the right divisor, each qualifying year is worth roughly £358 a year of pension. Against a cost of £956.80, a bought year takes a little under three years of drawing the pension to pay for itself, and then continues for life.
That arithmetic holds only where the year actually adds to your record, and that is not automatic. Settling that question first is what turns a top-up from a guess into a known quantity, and it takes one document to settle.
Not every year adds to every record. Two situations in particular mean a purchased year may add nothing at all:
This is why the forecast comes before the payment, not after it. Your State Pension forecast at gov.uk/check-state-pension shows your qualifying years, which specific years are available to fill, and what your record currently supports. It is the document that answers whether £956.80 would buy £358 a year, or nothing at all.
CF83 is the application used to pay voluntary National Insurance covering periods abroad, and the process has moved online.
GOV.UK now directs applicants to an online service rather than a postal form. The older route, in which CF83 appeared as the last two pages of HMRC's NI38 guidance booklet and was printed and posted, is the version most third-party articles still describe.
One hard limit is worth knowing before you start. GOV.UK states: "If you're over, or within 6 months of reaching State Pension age, we cannot process your application."
That is a cut-off, not a queue. Anyone approaching State Pension age who has been intending to deal with National Insurance gaps at some point has a narrower window than they may realise, and it closes six months before the date itself.
You will generally need details of your UK employment history, the dates you left the UK, and your circumstances abroad. HMRC then confirms what you are eligible to pay.
For several years HMRC operated an extended window allowing gaps to be filled back to the 2006/07 tax year, considerably further than the standard rules allow. That window closed on 5 April 2025.
The retrospective opportunity to top up a decade or more of gaps at a single point has therefore passed for most people. What remains is the ordinary position: voluntary contributions can usually be paid for the past six years, so the decision now is whether to keep filling gaps as they arise rather than to catch up on a lifetime of them.
Because the lookback rolls forward each April, a year that is fillable today may not be next year. GOV.UK's guidance is the authoritative source for your own position, and your forecast will show which years are currently available.
Working out whether topping up makes sense for you?

Even where a year would add to your record, the value of that addition varies with where you live and what else you have.
This is the largest single variable, and it is often left out of the arithmetic entirely.
GOV.UK applies a closed rule: the State Pension increases each year only if you live in the European Economic Area, Gibraltar, Switzerland, or a country with a UK social security agreement, and it names Canada and New Zealand as excluded even though agreements exist with both. Everywhere else, the pension is held at the rate you were first paid.
That cuts both ways, and the second way is easy to miss. In a frozen country the starting rate you achieve is the rate you keep for life, which makes the rate you reach at the outset matter more, not less. Our guide to the frozen UK State Pension sets out the country position, and the frozen State Pension calculator puts a figure on it over a retirement horizon you choose.
The State Pension is taxable, and which country has the right to tax it depends on the double taxation agreement between the UK and where you live. That affects the net value of every additional pound, and it varies considerably by destination. Our guide to the NT tax code covers how treaty claims work for UK pension income.
Some countries have social security agreements with the UK under which periods of contribution in each country can be taken into account when working out entitlement. Where that applies, the picture is wider than the UK record alone.
And for anyone whose retirement income is dominated by a defined benefit scheme, a SIPP or an overseas arrangement, the State Pension may be a modest component of the total. That does not make it unimportant, but it does change where it sits in the order of decisions.
The State Pension question rarely stands alone. It sits alongside private pension entitlements, the treaty position of your country of residence, foreign social security rights, and the shape of your retirement income as a whole.
A regulated specialist working across borders can read the forecast alongside those other elements, and assess the top-up question as part of the whole picture rather than as a standalone sum. The arithmetic above is simple; deciding what weight it deserves in your particular circumstances is not.

OpenGood to know
CF83 is the HMRC application to pay voluntary National Insurance contributions covering periods spent abroad, used to fill gaps in a UK National Insurance record so that they count towards the State Pension. It is now completed through an online service on GOV.UK rather than posted, and it historically appeared as the last two pages of HMRC's NI38 guidance booklet. GOV.UK notes one hard cut-off on the application itself: if you are over, or within 6 months of reaching State Pension age, HMRC cannot process your application.
Not for time spent abroad. GOV.UK states for the 2026 to 2027 tax year onwards that you cannot pay voluntary Class 2 National Insurance contributions for time abroad. This followed the Autumn Budget 2025 and took effect from 6 April 2026. Class 2 still exists as a class and still has a published rate of £3.65 a week for 2026/27, which is why stale guidance is easy to find, but that route is no longer open for periods abroad. For most expatriates the remaining voluntary route is Class 3.
Both buy qualifying years towards the State Pension, and a year bought either way counts the same. The difference was always cost and eligibility. Class 2 was substantially cheaper and required a work connection: under the rules up to 2025/26 you needed to have worked in the UK immediately before leaving and to be working abroad. Class 3 is the broader and more expensive class, at £18.40 a week for 2026/27. Since 6 April 2026 the comparison no longer arises for periods abroad, because Class 2 is not available for them.
For the 2026 to 2027 tax year onwards, GOV.UK requires that you have either previously lived in the UK for 10 years in a row, or paid 10 years of qualifying National Insurance contributions in total. That is a significant tightening: under the rules for 2025/26 and earlier the test was 3 years in a row of UK residence, or contributions for at least 3 years in total. Anyone who left the UK early in a career, before accumulating a decade, may no longer clear the entry test.
A full year of Class 3 costs £956.80 at the 2026/27 rate of £18.40 a week. For periods spent abroad, Class 3 can only be paid by those who meet the entry test that applies from the 2026 to 2027 tax year: 10 years living in the UK in a row, or 10 years of qualifying contributions in total. The full new State Pension is £241.30 a week, which is about £12,548 a year, and GOV.UK states that if your National Insurance record started after April 2016 you will need 35 qualifying years to get the full rate. On that basis a qualifying year is worth roughly £358 a year of pension, so a bought year takes a little under three years of drawing the pension to pay for itself. That arithmetic only holds if the year actually adds to your record, which is why the forecast comes first.
No, and this is the single most expensive misunderstanding in this area. A year adds nothing if your record already supports the full amount, and people who were contracted out before April 2016 are a particular case: GOV.UK states that if you were contracted out, you will usually need more than 35 qualifying years to get the full rate of new State Pension, so the relationship between years and pounds is not a simple one. Your State Pension forecast at gov.uk/check-state-pension shows which specific years are fillable and what filling them would do. Checking it before paying is what separates a sound purchase from a wasted one.
