National Insurance Contributions Record: Check Yours
Your National Insurance record is the ledger behind your State Pension. It tracks every tax year you paid in, were credited for, or missed, and one unchecked gap can quietly shrink the pension you eventually receive. Here is how to read it, what counts, and when filling a gap is worth paying for.
Key takeaways
- Your NI record shows whether each tax year counts as a qualifying year.
- You normally need 35 qualifying years for the full new State Pension, and at least 10 for any.
- A qualifying year can come from paying NI, receiving NI credits, or voluntary contributions.
- Gaps can usually be filled for the previous six tax years; check your forecast first.
- Paying only helps if it raises your forecast.
Most people never look at their National Insurance record until retirement is close. Yet it is built one tax year at a time, and years lost to a career break, time abroad, or low earnings cannot always be bought back later. Checking it is free, and it can reveal gaps while there is still time to fix them.
What your NI record shows
Your record is a year-by-year history of your National Insurance contributions and credits, held by HM Revenue and Customs. For each tax year, from 6 April to 5 April, it shows what you paid, any credits received, and whether the year counts as a qualifying year. The online service shows payments up to the start of the current tax year, so the year you are in now will not appear yet.
It is not a bank balance. National Insurance is not saved in your name; your record simply determines your entitlement to certain benefits, above all the State Pension. A year marked as not full does not count towards your pension, even if you paid something in that year, for example if you worked only part of the year and fell short of the threshold.
Qualifying years: the 35-year and 10-year rules
Under the new State Pension, for people reaching State Pension age on or after 6 April 2016, you normally need 35 qualifying years for the full amount and at least 10 to receive anything at all. Each year below 35 cuts your pension by one thirty-fifth of the full rate. For 2026/27 that full rate is £241.30 a week, about £12,548 a year, so each qualifying year is worth roughly £6.89 a week, about £358 a year, for life.
| Qualifying years | Weekly pension at the 2026/27 full rate |
|---|---|
| 35 (full) | £241.30 |
| 30 | £206.83 |
| 20 | £137.89 |
| 10 (minimum) | £68.94 |
| Under 10 | Nothing under the new State Pension rules |
A qualifying year can be earned several ways. Employees earn one by paying Class 1 National Insurance, or by earning above the lower earnings limit even where no National Insurance is deducted. Self-employed people earn one through Class 2 contributions, while Class 4 contributions on profits do not count on their own, as our guide to Class 4 National Insurance explains. NI credits can also earn one, for example while claiming Child Benefit for a child under 12 or Carer's Allowance. If you paid in before April 2016, transitional rules apply, so your personal forecast matters more than the headline rule.
How to check your record, step by step
Go to the GOV.UK "Check your National Insurance record" service and sign in. If you do not have sign-in details, you can create them during the process, and you will normally be asked to prove your identity with photo ID such as a passport or driving licence. Then note every year marked as not full, because the fix may differ: one gap may be covered by missing credits, another only by paying.
Most importantly, open your State Pension forecast too. It shows what you are on track to receive and how voluntary contributions would change it. Never pay to fill a gap without checking whether that specific year would raise your forecast. If you cannot use the online service, request a printed statement instead, though not for the current or previous tax year. For the employer side of the system, see our guide to employers NI rates and thresholds.
Worked example: is filling three gaps worth it?
Imagine Sarah, aged 58, with 28 qualifying years and three recent gaps she could fill with voluntary Class 3 contributions. At the 2026/27 full rate of £241.30 a week, her 28 years give her 28 divided by 35, multiplied by £241.30, which is £193.04 a week. Filling all three gaps takes her to 31 years: 31 divided by 35, multiplied by £241.30, which is £213.72 a week, a gain of £20.68 a week, about £1,075 a year, for life.
At the 2026/27 Class 3 rate of £18.40 a week, each year filled costs £956.80, so three cost £2,870.40. That gives a payback period of about two years and eight months from State Pension age. After that, the extra £1,075 a year keeps coming, provided her forecast confirms all three years would raise her pension. If she is already on track to reach 35 years through future work, filling them adds nothing and the £2,870.40 would be wasted.
Gaps: credits first, payment second, deadlines always
Before paying anything, check for missing NI credits: claiming them can turn a gap year into a qualifying year for free. If you were entitled to credits but never received them, claim those first. If payment is the only route, voluntary contributions can normally only be made for the previous six tax years. Older gaps are generally closed, following the end of the temporary extended window that allowed payments much further back.
That deadline makes an early check valuable: a gap from six years ago may still be fillable today and gone next year. Do not rush: a voluntary payment is hard to undo. Check the record, forecast, and credits, and only then decide.
