The thresholds for employee and employer national insurance contributions (NICs) have been increased by £1 a week for the 2021/22 tax year. Employees will be liable to 12% NICs between £184 and £967 a week (£50,270 a year). Employer contributions will start at £170 a week.
The self-employed will pay 9% Class 4 NICs on profits between £9,570 and £50,270.
The higher rate tax threshold for 2021/22 will be aligned with the £50,270 NIC upper earnings limit and the personal allowance will be uprated by the same percentage to £12,570 for 2021/22. Note that there are rumours that the chancellor may freeze the personal allowance in the budget.
