Unless the Chancellor makes an announcement to the contrary on 23 March, which is very unlikely, the rates of National Insurance Contributions for workers and employers increase by 1.25% from 6 April 2022. This is to provide extra funding for health and social care and will become a separate Levy from 2023/24.

The starting thresholds for employee and employer national insurance contributions (NICs) have also been increased. Employees will be liable to 13.25% NICs between £190 and £967 a week (£50,270 a year). Employer contributions at 15.05% will start at £175 a week.

For 2022/23 the self-employed will pay 10.25% Class 4 NICs on profits between £9,880 and £50,270. Employees and the self-employed will pay 3.25% on earnings or profits in excess of £50,270 from 6 April 2022.
