Use this service provided by HMRC to estimate how much Income Tax and National Insurance you should pay for the current tax year (6 April 2018 to 5 April 2019).

This tells you your take-home pay if you don’t have any other deductions, such as pension contributions or student loans.

If you’re self-employed, the self-employed ready reckoner tool can help you budget for your tax bill.

You may be able to claim a refund if you’ve paid too much tax.
