Most self-employed people are required to pay Class 4 National Insurance contributions (NICs) if their profits are £12,570 or more a year. Class 4 NIC rates for the tax year 2024-25 are 6% for chargeable profits between £12,570 and £50,270 plus 2% on any profits over £50,270.
A number of categories of people are exempt from paying Class 4 NICs, these include:
- People under the age of 16 at the beginning of the year of assessment.
- People over State pension age at the beginning of the year of assessment. A person who attains State pension age during the course of the year of assessment remains liable for Class 4 NICs for the whole of that year.
- People receiving profits in their capacity as a trustee, executor or administrator of a person liable to tax.
The mandatory payment of Class 2 National Insurance Contributions (NICs) for the self-employed was abolished effective from 6 April 2024. It can be beneficial for some self-employed people who do not pay NICs through self-assessment to make voluntary Class 2 NICs. This can help them access certain contributory benefits including the State Pension. It is important to confirm that this would be beneficial before making any voluntary payment. The current weekly rate for making voluntary Class 2 NICs is £3.45.
