The forecast shows what you have built so far and what you could reach if you keep contributing. Confusing the two is the reason people buy years they did not need.
The State Pension forecast is the single most useful document in UK personal finance and one of the most misread. It contains two headline figures that look similar and mean very different things: the amount you have accrued to date, and the amount you could receive if you continue contributing to State Pension age. People who act on the wrong one either buy contributions they do not need or fail to buy ones they do.
The Two Numbers
| Figure | What it means |
|---|---|
| Accrued to date | What you have earned so far, based on your record up to the last completed tax year |
| Forecast at State Pension age | What you would get if you keep contributing at the assumed rate until then |
The gap between them is future contributions you have not made yet. Someone in their forties with twenty-five qualifying years and twenty working years ahead will usually reach the full amount without buying anything, because the years they are about to work will get them there. That is exactly the person most likely to buy voluntary contributions unnecessarily.
Voluntary contributions only help if you will not otherwise reach 35 qualifying years. Contributions beyond the full amount add nothing whatsoever. Check the forecast before paying, and check whether future working years will close the gap for free.
The Basics Behind the Figures
- The full new State Pension is currently £11,502 a year.
- You generally need 35 qualifying years for the full amount.
- You need a minimum of 10 qualifying years for any State Pension at all.
- Years are built from National Insurance contributions or credits — see gaps in your NI record.
Why Contracting Out Complicates It
Anyone who was in a contracted-out occupational scheme before the system changed has a starting amount calculated under transitional rules that compare entitlement under the old and new systems. The result is that the neat relationship between years and pension does not hold: someone with well over 35 years may still show less than the full amount, because part of their entitlement was built in a scheme that contracted out of the additional State Pension.
This is not an error and it is not something to argue with. It also means general arithmetic about years is unreliable for that cohort — the forecast is the authority, and if it says more years will increase the amount, they will.
What the Forecast Does Not Tell You
- Your State Pension age is stated, but it is set by legislation and has been changed before.
- Future increases are not projected in real terms. The figures are in today's money.
- Whether a gap can still be filled. Time limits apply to how far back voluntary contributions can go, and the forecast is not a deadline reminder.
- Whether living abroad will freeze it. Increases are only paid in some countries — see retiring abroad.
- How it will be taxed. The State Pension is taxable income, paid without deduction, which usually means tax on it is collected through the code on another pension.
Check the Year-by-Year Record Too
Behind the headline figures is a year-by-year record showing which years are full, which are partial, and which are missing. That is what you need before deciding anything, because it identifies the specific years to consider filling and whether any can be credited rather than bought. Partial years are often the cheapest to complete.
Getting Access
The forecast and the record are available through your HMRC and government online accounts, which depend on identity verification that assumes a UK phone and credit history. Anyone abroad, or anyone who has lost their verification route, should read HMRC online access from abroad — the decision about voluntary contributions is time-limited and effectively impossible to make without this document in front of you.
Frequently Asked Questions
What is the difference between the two figures on my forecast?
One is what you have accrued to date from your record so far, the other is what you would receive if you keep contributing to State Pension age. Confusing them is why people buy contributions they do not need.
I have more than 35 years but not the full amount. Why?
Almost certainly contracting out. A starting amount calculated under transitional rules can leave someone with many years still short, because part of their entitlement was built in a contracted-out scheme.
Should I buy voluntary contributions?
Only if you will not otherwise reach 35 qualifying years. Someone with many working years ahead usually gets there for free, and contributions beyond the full amount add nothing.
Is the State Pension taxable?
Yes. It is taxable income but is paid without deduction, so tax on it is usually collected through the code applied to another pension or employment.
