Self-Employed National Insurance Contributions

Self-employed individuals earning £12,570 or more annually must pay Class 4 National Insurance Contributions (NICs). For 2024-25, rates are 6% on profits up to £50,270 and 2% above this. Certain groups are exempt, and voluntary Class 2 NICs may be beneficial.

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. There are no changes to these rates for 2025-26.

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 under ITTOIA2005/S8.

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 voluntarily Class 2 NICs. This can help them to 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 and is increasing to £3.50 in 2025-26.

Most self-employed individuals pay Class 2 and Class 4 NICs through self-assessment. Certain self-employed roles, such as examiners, moderators, invigilators, and ministers of religion without a salary do not pay National Insurance through self-assessment but may want to pay voluntary contributions.
