Voluntary Class 2 National Insurance contributions
You may be entitled to a refund if you paid voluntary Class 2 National Insurance contributions and you think you made an error when the payment was made.
You will not be entitled to a refund if the error relates to a change of circumstances after the payment was made.
A refund of voluntary Class 2 National Insurance contributions may affect your entitlement to State Pension and other benefits.
Before you apply for a refund, you:
- should contact the Department for Work and Pensions to check if and how it may affect your entitlement to State Pension
- can check what other benefits your voluntary Class 2 contributions count towards as these may be affected by a refund — you should contact your local Job Centre Plus to check if and how these other benefits will be affected
When to apply
You should apply within 6 years of the tax year you’re claiming for. For example, if you are applying for a refund for the 2023 to 2024 tax year, you should apply before 6 April 2030.
If you apply after 6 years, you will need to include reasons for your late application when you apply.
