How do I check my National Insurance record for gaps?
Your State Pension is built from qualifying years, not from what you paid. Gaps are common, often invisible, and only sometimes worth filling.

Short answer
Check your record and forecast together in the HMRC app or through your personal tax account on GOV.UK. The forecast shows what you are on track for and how many more qualifying years you need; the record shows which years are incomplete. Voluntary contributions can fill some gaps, but not every gap increases the forecast, so check the forecast before paying anything.
National Insurance buys entitlement rather than funding a pot. What matters is the number of qualifying years, and there are two thresholds: a minimum number before you get any new State Pension at all, and a larger number for the full amount. Years can be incomplete for reasons that had nothing to do with avoiding contributions — low-paid or part-time work, self-employment with small profits, time abroad, or a period claiming a benefit that should have carried a credit but did not.
Step by step
- Get access to your personal tax account.Either the HMRC app or the GOV.UK personal tax account, both of which need identity verification the first time. It is the only complete view of your own record.
- Read the State Pension forecast first, not the record.The forecast tells you what you are on track to receive, the earliest date you can claim, and how many more qualifying years would increase it. Everything else follows from that number.
- Then look at the year-by-year record.Each tax year is shown as full, not full, or with a note about credits. Incomplete years show what, if anything, can be paid to complete them and by when.
- Check whether a gap is actually reducing your forecast.If you already have or will reach the years needed for the full amount through future working years, filling an old gap adds nothing. This is the single most important check, and the reason to read the forecast before paying.
- Look for missing credits before paying for anything.Credits are free and cover many situations: receiving Child Benefit for a child under twelve, caring, some benefits, jury service, and more. If you were entitled to a credit that is missing, applying for it is better than buying the year.
- Check Specified Adult Childcare Credits if you look after a grandchild.Where a working parent receives Child Benefit and does not need the credit themselves, a grandparent or other family member providing childcare can apply to have it transferred. It is widely unclaimed.
- Understand the deadlines on voluntary contributions.Generally you can fill gaps in the last six tax years. Extended windows have been opened and then closed in recent years, so check the current deadline on GOV.UK rather than assuming.
- Call the Future Pension Centre before paying voluntary contributions.This is the standard advice from both DWP and MoneyHelper. They confirm whether a specific year would increase your forecast. Paying without checking is how people buy years that do nothing.
- Check the record again a few months later.Voluntary contributions and credits take time to appear. Verify they landed on the right year — misallocated payments happen and are much easier to fix early.
Common mistakes
- Buying voluntary contributions without checking the forecast — Not every gap increases the pension. People with a pre-2016 contracted-out history in particular can find that extra years make no difference.
- Assuming credits are automatic — Some are, some are not. Child Benefit credits are only awarded where a claim exists — which is a strong argument for claiming Child Benefit even at a nil rate.
Questions people ask
How many qualifying years do I need for the full State Pension?
There is a minimum number before any new State Pension is paid and a higher number for the full rate, and the figures are on GOV.UK. Your own forecast is more useful than the general numbers because it accounts for your contracted-out history.
Are voluntary National Insurance contributions worth it?
Sometimes, and it depends entirely on whether the year increases your forecast. Check the forecast, then confirm with the Future Pension Centre before paying. Neither GuideHQ nor any general guide can answer it for your record.
I stayed at home with children — do I have gaps?
Not if Child Benefit was claimed in your name for a child under twelve, which carries a credit. Gaps commonly appear where the claim was in a working partner's name instead. That can sometimes be transferred retrospectively.
