Who pays National Insurance
You pay mandatory National Insurance if you’re 16 or over and are either:
- an employee earning above £184 a week
- self-employed and making a profit of £6,515 or more a year
You may be able to pay voluntary contributions to avoid gaps in your NI contributions.
You need a National Insurance number before you can start paying National Insurance contributions.
If you earn between £120 and £184 a week, your contributions are treated as having been paid to protect your National Insurance record.
National Insurance classes
There are different types of National Insurance (known as ‘classes’).
The type you pay depends on your employment status and how much you earn.
When you stop paying
If you’re self-employed you stop paying:
- Class 2 National Insurance when you reach State Pension age
- Class 4 National Insurance from 6 April (start of the tax year) after you reach State Pension age
