Class 4 National Insurance
Class 4 National Insurance is one of the two kinds of National Insurance (NI) that you pay if you’re self-employed.
The other kind is Class 2.
You only start paying Class 4 NI once you earn over £8,632 a year (from all your income sources combined).
Class 4 NI is 9% for self-employment profits between £8,632 and £50,000, and 2% on anything above £50,000.
What you need to remember about Class 4 National Insurance:
- you will pay this yourself through a Self Assessment tax return – same as with Income Tax on your self-employment earnings
- this is on top of Class 2 National Insurance
- you must pay Class 4 National Insurance even if you earn under the Personal Allowance
- if you’re also working as an employee and your total earnings are over £8,632 (for example, 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.
