Last month we reported some self-employed taxpayers who made voluntary class 2 National Insurance Contributions (NICs) for 2022/23 and received an unexpected refund from HMRC, which may have been an error. HMRC has now provided an update regarding this issue.


What is the issue?

  • Voluntary contributions are usually made to enable taxpayers to secure their entitlement to the State pensionMaternity allowance and employment and support allowance.
  • Due to a processing error, some taxpayers have received a self-assessment tax calculation (SA302) indicating that the payment of NIC class 2 contributions for 2022/23 was made late, despite being paid before the 31 January 2024 deadline. 
  • Affected taxpayers will have: 
    • Received a refund of class 2 NIC.
    • Received a credit on their Self Assessment account.
    • Received a credit which has been allocated against a different liability. 
  • Affected taxpayers may now find a gap in their NIC records which could impact their entitlement to allowances. 

What should you do?

  • HMRC have advised they can't automatically amend taxpayers' records, despite the payment being made on time. 
  • Taxpayers are advised to check thier online account or use the HMRC App to check thier records. 
  • Unfortunately, the New digital NI tool is not available to self-employed individuals. 
  • If there is a gap in taxpayers' NIC records, the only way to resolve the issue is for taxpayers to contact the NI contributions office. 
  • Agents should check the SA302 self-assessment calculations to identify if they have clients with this issue.
