For employees

In addition to income tax, all employees earning more than £12,570 a year pay Class 1 NICs. The main rate of Class 1 NICs will be cut from 12% to 10% from 6 January 2024. This will come into effect from January 2024 and, over a full year, the average worker on £35,400 will receive a NIC reduction of over £450. Workers earning more than £50,270 a year will receive a NIC reduction of £754.

The Class 1 NIC rate will remain at 2% for earnings above £50,270 a year.

Similarly, there are no changes to the rate of employer’s Class 1 NICs, which remains at 13.8%.

For the self-employed

Self-employed individuals with profits of more than £12,570 a year pay two types of NIC: Class 2 and Class 4.

  • Class 2 NICs have been at a flat rate sum of £179.40 a year (£3.45 a week) in 2023/24 but no one will be required to pay the charge from 6 April 2024.
  • The main rate of Class 4 NICs will be cut from 9% to 8% from 6 April 2024. Class 4 NICs will continue to be calculated at 2% on profits over £50,270.

Taken together these changes will result in an average self-employed person with profits of £28,200 saving £336 in 2024/25.

Class 2 NICs currently provide the self-employed with access to a range of state benefits, including the State Pension. From 6 April 2024, self-employed people with annual profits;

  • Above £12,570 – will continue to receive access to the benefits.
  • Between £6,725 and £12,570 – will continue to receive access to the benefits, via a National Insurance credit.
  • Under £6,725 (or with losses) – will be able to continue to pay Class 2 NICs on a voluntary basis in order to maintain their access to state benefits. Class 2 NICs had been due to increase in 2024/25 but it seems that these will be maintained at the current £3.45 weekly level for those in this bracket.
