Employee National Insurance since 2016
Few taxes have moved as often. The threshold rose slowly from £8,060 to £9,568, then leapt to £12,570 in July 2022. The main rate went up to 13.25% for seven months in 2022, came back to 12%, and was then cut twice in 2024 to 8%. Employers went the other way in April 2025: their rate rose to 15% and their threshold fell to £5,000. Both charts are drawn from the same table the calculator uses, including the mid-year changes.

Frequently Asked Questions
- What is the difference between Class 1 and Class 4 NI?
- Class 1 NI is paid by employees (and matched by employers) based on gross earnings. Class 4 NI is paid by the self-employed based on taxable profits, usually via self assessment.
- What are the NI thresholds for 2026/27?
- You start paying NI at £12,570 — the Primary Threshold for Class 1 employees and the Lower Profits Limit for Class 4 self-employed. Between £12,570 and £50,270 the main rate applies: 8% for Class 1, 6% for Class 4. Above £50,270 the rate drops to 2%. Worked example: an employee on £45,000 pays 8% on the £32,430 between the two thresholds, giving £2,594.40. A self-employed person with the same £45,000 profit pays 6% on that amount, giving £1,945.80. On £60,000, an employee pays £3,016 at the main rate plus £194.60 at 2%, totalling £3,210.60.

The threshold at which you start paying jumped from £9,880 to £12,570 in July 2022 to match the personal allowance. An employee on £45,000 paid £4,251.84 in 2021/22 and pays £2,594.40 in 2026/27.
