Class 4 National Insurance

Class 4 National Insurance is one of the two types of National Insurance (NI) that you pay if you’re self-employed.

The other type is Class 2.

You start paying Class 4 NI once you earn over £9,568 a year (from all your combined income sources).

Class 4 NI is 9% for self-employment profits between £9,568 and £50,270, and 2% on anything above £50,270.

What to remember about Class 4 National Insurance:

  • You pay it yourself through a Self Assessment tax return – as with Income Tax on your self-employment earnings
  • It is in addition to Class 2 National Insurance
  • You must pay Class 4 NI even if you earn less than the Personal Allowance
  • If you’re also working as an employee and your total earnings are over £9,568 (e.g. you work in sales during the day and freelance as a tutor in the evenings), you’ll pay both Class 1, Class 2, and Class 4 NI.
