At Class 2 rates this pays for itself in seven months
A qualifying year costs about £182 and adds about £342 a year to your State Pension for life. The catch is that most people assume they are on Class 3, never apply, and lose a year off the back of the six-year window every 5 April.
Why this is the best-value decision most expats never make
A qualifying year of National Insurance adds roughly £342 a year to your State Pension, for the rest of your life. At Class 2 rates — about £3.50 a week, or £182 for a full year — that is an outlay you recover in the first seven months of drawing the pension, and everything after that is profit. There is very little else available to a private individual that looks remotely like it.
Class 3, at about £17.75 a week or £923 a year, is nearly five times the price and still pays for itself inside three years. So the question that matters is not whether to buy, but which class you qualify for — and that is the part people get wrong, usually by assuming the expensive answer and never applying.
Class 2 or Class 3
Class 2 requires that you were employed or self-employed immediately before you left the UK, that you have previously lived in the UK for at least three years or paid three years of contributions, and that you are working abroad now. Not working overseas, or retired, generally means Class 3.
HMRC decides the class when it processes your CF83 application, not you. Applications from abroad take months, so this is worth starting well before a deadline rather than in the week of one.
The six-year window, and the deadline nobody announces
You can normally fill gaps going back six tax years, and that window rolls. Every 5 April the oldest year drops off permanently — no appeal, no exception, no discretion. A year that is fixable in March is simply gone in April, and nobody writes to tell you it happened.
When the honest answer is no
- You already have 35 qualifying years. More years add nothing to the new State Pension at all. This is the first thing the review checks and it saves people thousands.
- You are retiring somewhere the pension is frozen. In Canada, Australia, New Zealand, South Africa, Hong Kong and most of the world outside the EEA, your State Pension never rises again once you claim it. The years are still worth buying, but their real value erodes every year of retirement — which changes how many to buy and when.
- Credits you have forgotten. Years of child benefit, carer's allowance or certain benefits may already be on your record as credits.
The £149 review pulls your actual record from HMRC rather than guessing at it, establishes which class you qualify for, works out which specific years are worth buying and in what order, and files the CF83.
Asked about this constantly
Class 2 or Class 3 — which am I?
Class 2 needs you to have been working immediately before you left and to be working abroad now, plus three years of prior UK residence or contributions. HMRC decides when it processes your CF83.
How far back can I go?
Six tax years, on a rolling window. Every 5 April the oldest year drops off permanently, with no appeal and no exception.
Is it worth it if my pension will be frozen?
Usually still yes, but less so. In a frozen country the pension never rises again after you claim it, so the real value erodes each year — which changes how many years to buy and when.
What if I already have 35 years?
Then more years add nothing to the new State Pension. Checking that first is the whole point of the £149 review, and it is the finding that saves people the most.
