Unlike employees who have NI automatically deducted from their salary, self-employed individuals must pay their contributions. The amount you pay depends on your profits and falls under two categories:
- Class 2 NI – A flat-rate contribution if your profits exceed the small profits threshold.
- Class 4 NI – A percentage-based contribution on profits above a set limit.
Who Needs to Pay National Insurance?
If you are self-employed and earn above a certain threshold, you must pay National Insurance for the self-employed. You are considered self-employed if you:

In case your earnings are below the threshold, you can make optional contributions to maintain your NI record for future benefits.
