Hi homework23,
The deadline for paying voluntary National Insurance contributions for that tax year has been extended to 31/07/2023.
You will need to check with the Future Pension Centre if paying for that year will benefit you. If you pay without checking with them and your pension does not increase, you won’t be entitled to a refund so it is important that you obtain that information before sending any payments to HMRC.
You should also contact our National Insurance team for us to check that year and confirm if there is a shortfall or not.

Thank you.
