HMRC is contacting up to 800,000 self-employed taxpayers to alert them to potential gaps in their National Insurance contributions (NICs) that could reduce their State Pension entitlement. The letters, which began rolling out in 2026, focus on individuals who became self-employed between 2015 and early March 2024.
According to HMRC, the issue stems from several factors: Class 2 NICs paid after the 31 January deadline, or payments that were incorrectly allocated to clear outstanding tax liabilities instead of NICs. Taxpayers who receive a letter or use HMRC's online pension forecast tool to spot gaps will be allowed to make contributions beyond the usual six-year limit, at the original rate.
Priority for Those Near Retirement
Of the 800,000 affected, approximately 160,000 are either already past State Pension age or within two years of reaching it. These individuals are being contacted first, with letters scheduled to arrive by summer 2027. HMRC has advised that no immediate action is required; affected taxpayers will be notified directly over the coming months.
Receiving a letter does not automatically mean there is a shortfall. The first step for taxpayers is to check whether additional qualifying years are actually needed. HMRC urges recipients to review their Self Assessment tax returns for previous years to confirm whether Class 2 NICs were made.
Check for Missing Credits
Taxpayers should also verify that any National Insurance credits, such as those for caring responsibilities, have been correctly recorded. Missing credits could affect their qualifying year total, potentially reducing the State Pension they are entitled to.
If gaps are identified and filling them would increase the State Pension, taxpayers can follow HMRC's instructions to make voluntary Class 2 NICs. This option allows them to pay at the original rate, which is typically lower than the current rate.
Impact on Pension Entitlement
The State Pension is based on a person's National Insurance record. To qualify for the full new State Pension, individuals typically need 35 qualifying years. Those with fewer years receive a proportionally lower amount. For the 800,000 affected, this could mean a significant reduction in retirement income if gaps are not addressed.
HMRC's proactive approach aims to prevent unexpected shortfalls. By contacting taxpayers early, especially those closest to retirement, the department hopes to give individuals ample time to make voluntary contributions and secure their full pension entitlement.
Next Steps for Taxpayers
Those who receive a letter should not panic. Instead, they should:
- Check their National Insurance record online via the HMRC app or website.
- Review their Self Assessment tax returns to see if Class 2 NICs were paid.
- Verify that any credits for caring, unemployment, or other qualifying benefits are recorded.
- If gaps exist, consider making voluntary Class 2 NICs at the original rate, as instructed by HMRC.
HMRC has not specified a deadline for making voluntary contributions, but encourages taxpayers to act promptly to avoid missing out on the opportunity to boost their pension.
Background and Future Communications
This issue affects a significant portion of the self-employed population, which has grown considerably since 2015. The letters are part of a broader effort by HMRC to ensure accurate pension records. Further letters will be sent to the remaining 640,000 taxpayers over the next year or so.
HMRC's online pension forecast tool is available for all taxpayers to check their State Pension entitlement and identify any gaps. The department advises that even those who do not receive a letter should use this tool to stay informed.
