If you’re self-employed and your profits are above the earnings threshold, you’ll pay the 1.25 percentage points increase in NICs for the 2022/23 tax year and the separate 1.25% levy from 6 April 2023.
The NIC increase does not apply to Class 2 NICs, although Class 2s on earnings between £6,725 and £9,880 will increase to £3.15 per week in 2022/23 (from £3.05 in 2021/22).
Need to know! The income threshold after which people start paying National Insurance will rise to £12,570 in July 2022, a £3,000 a year increase.
