Question 1

Is it worth buying missing NI years?

Accepted Answer

It depends on which gaps increase your State Pension and what they cost to fill. Voluntary contributions do not always increase the amount, particularly where pre-2016 or contracted-out history affects the calculation. Check your official forecast and whether free NI credits are available. The calculator is a simplified comparison, not an individual entitlement check.

Question 2

How much does a voluntary NI year cost?

Accepted Answer

The Class 3 voluntary National Insurance contribution rate for 2026/27 is £956.80 per year. This rate is set annually by HMRC. Self-employed individuals may be able to pay the cheaper Class 2 rate instead, which also counts as a qualifying year. You can pay for gaps going back several years, though some recent years may be charged at the rate that applied at the time.

Question 3

How much extra state pension do I get per year of NI?

Accepted Answer

For a simple record starting after April 2016, a qualifying year normally represents one thirty-fifth of the full new State Pension, subject to meeting the minimum qualifying conditions and the full-rate limit. At 2026/27 rates this is about £359 a year. Earlier or contracted-out records use transitional calculations, so 35 years is not a universal maximum and an extra paid year may add nothing. Use your official forecast to check the effect of a specific gap.

Question 4

How do I check my NI record?

Accepted Answer

You can check your National Insurance record online at gov.uk/check-national-insurance-record. You’ll need a Government Gateway account. Your record shows each tax year, whether it was a full year, and any gaps. It also shows how many qualifying years you have and how many more you need for the full state pension. HMRC can also tell you how much it would cost to fill specific gaps.
