Income Tax calculator

This calculator will provide an estimate of your income after tax and National Insurance.

So, if your salary is changing - perhaps you are changing jobs - you can work out what difference this could make to your income.

Simply enter your current gross annual salary (the amount of money you make per year from all sources before tax and National Insurance is taken out). The calculator will then show you the total annual income tax deductions, and what your remaining earnings could be on an annual, monthly or weekly basis.

Easy to use features

  • Available across a range of devices, including the iPad.
