Voluntary Class 3 NIC costs £824.20 per year (2025/26) and can be one of the best “investments” you can make. This checker works out whether filling your gaps is worthwhile.

Free NI Credits You May Have Missed
Before paying voluntary NIC, check whether you are entitled to free credits for years you think are gaps. Common credits include:
| Situation | Credit available |
|---|---|
| Claiming Child Benefit for a child under 12 | Class 3 credits (full qualifying year) |
| Carer’s Allowance recipient | Class 1 credits (full qualifying year) |
| Carer’s Credit (20+ hours caring, not on CA) | Class 3 credits (apply on form CF411A) |
| Statutory sick pay or Statutory Maternity Pay period | Class 1 credits |
| Universal Credit claimant doing work-related activity | Class 3 credits |
| Armed forces or partner of armed forces member posted abroad | Class 3 credits available |
It is always worth checking credits before paying voluntary NIC — you may be entitled to free years you did not know about.
Voluntary NIC for Those Living Abroad
UK nationals living abroad can pay voluntary Class 2 NIC (cheaper than Class 3) if they were working in the UK immediately before leaving and continue to work abroad. Class 2 costs just £3.45/week (£179.40/year) but achieves the same result as Class 3 for State Pension purposes. Contact HMRC’s National Insurance abroad team (NI38 guidance) to check whether you qualify for Class 2 rather than Class 3.
Frequently Asked Questions
No. Once you reach State Pension age, you stop paying NIC and cannot make voluntary contributions to increase your State Pension. You must fill any gaps before you reach State Pension age. If you are close to State Pension age and have gaps, act urgently. There is also no benefit in having more than 35 qualifying years — additional years beyond 35 do not increase your pension further.
Yes, in most cases. The State Pension is paid on top of any occupational or private pension. However, those who were in contracted-out defined benefit pension schemes before 2016 may have a “starting amount” for the new State Pension that is lower than the full rate — this is because they built up a State Second Pension equivalent within their occupational scheme. Check your State Pension forecast at gov.uk/check-state-pension to see your personal starting amount and how many years you need.
