When you’re self-employed, you have to pay your National Insurance contributions yourself in your annual Self Assessment, together with any income tax you might owe.
You pay no NI contributions on the first £12,570 that you make.
You will also have to pay £2,126 (6%) on your income between £12,570 and £48,000.
National Insurance is a tax that we all have to pay in the UK to be entitled to claim certain state provided benefits. You have to pay it whether you’re employed or self-employed – although the type (or class) that you pay is determined by your employment status.Â
Here are some of the benefits that you’re entitled to as a result of paying National Insurance:
Well, of course, you could just use our National Insurance calculator above to see exactly what you’ll end up paying, but if you’d like a breakdown of the rates, check out the table below.
| NI class | Who pays? | How? | How much? |
| Class 1 | Employees earning over £12,570 | Deducted from salary | 8% (or 2% if you earn over £242 per week) |
| Class 1A/1B | Employers | Paid via PAYE | 13.8% |
| Class 2 | Abolished from the 2024/25 tax year | ||

Well, let’s say 2022 was a weird year. After four chancellors, three prime ministers and numerous mini and maxi financial budgets, the National Insurance rate changed quite a lot of times. As a result, your calculation isn’t as straightforward as it is in more stable tax years. Take a look at our blog on the 2022 budget to see what happened.
No, not from the 2024/25 tax year.
When you earn less than £12,570 in a tax year, you’re now exempt from paying both Income Tax and National Insurance. The first £12,570 of your income is known as the Personal Allowance. You don’t pay Income Tax on it unless you earn over £100,000, at which point you start to lose your eligibility to it.Â
The table above shows you how much National Insurance you’ll owe based on your earnings.
