How much does voluntary Class 3 National Insurance cost in 2026/27?

Full answer

Class 3 National Insurance contributions are voluntary payments that allow individuals to fill gaps in their NI record and qualify for, or increase, their State Pension entitlement. 2026/27 weekly rate The Class 3 weekly rate for 2026/27 is GBP 17.45 (set by the Social Security (Contributions) Regulations and uprated by CPI each April). For a full tax year (52 weeks) this is GBP 907.40. Why pay Class 3 NI? To receive the full new State Pension (GBP 230.25 per week in 2026/27, GBP 11,973 per year) you need 35 qualifying years. A minimum of 10 qualifying years is needed to receive any new State Pension. Each additional qualifying year adds 1/35th of the full pension -- approximately GBP 6.58/week or GBP 341.20 per year. Payback period calculation Cost of one qualifying year: GBP 907.40 (2026/27 rate -- past years may differ). Benefit: GBP 341.20/year extra State Pension. Payback period: GBP 907.40 / GBP 341.20 = approximately 2.66 years. Given average retirement lasts 15-25 years, this is almost always financially worthwhile for those with gaps. How to check your record View your NI record and State Pension forecast at gov.uk/check-state-pension. Gaps are shown by tax year. You can also use the online calculator to see how filling each gap affects your pension. How to pay Apply via the Government Gateway (Check Your State Pension service). HMRC will confirm whether a gap can be filled and provide payment details. Payment can be made by bank transfer, cheque or BACS. Deadlines for past years Normally gaps can only be filled going back 6 tax years. However, a special extension allowed people to fill gaps back to 2006/07. This extended deadline closed on 5 April 2025. For 2026/27, the standard 6-year window applies (gaps in 2020/21 onwards can be filled until April 2027). Class 3 vs Class 2 Class 2 NI (GBP 3.45/week for 2026/27) is available to self-employed people with profits above the Small Profits Threshold. If you were self-employed in a gap year, it is substantially cheaper to pay Class 2 for that year rather than Class 3 -- check with HMRC whether Class 2 is available for your circumstances.
