Income Tax calculator

This calculator will provide an estimate of how much income tax and National Insurance you may pay, based on your earnings.

Simply enter your gross annual salary, which is the amount you get before income tax and National Insurance. The calculator will then show you your total annual income tax and National Insurance deductions, and how much your earnings could work out to be on an annual, monthly or weekly basis after these deductions.
