National Insurance
Anyone who earns income in the UK may need to pay National Insurance (NI) - whether you're employed or self-employed.
The amount you pay will vary depending on your income and employment status.
You can use our calculator above to work out how your NI contributions will be in the current tax year.
We have updated our calculator to reflect the changes the Chancellor announced on Wednesday 23 March 2022 in his Spring Statement and the health and social care levy being introduced in April 2022.
The calculator makes standard assumptions about employed and self-employed people to estimate your tax breakdown. So bear in mind that what you will take home also depends on other factors such as your pension contributions and student loan repayments - and can vary depending on your tax code.
The figures shown (for all years apart from 2022-23) indicate what you'd owe on an annual basis, and assume you've worked for the full tax year.
