Income tax calculator

Income tax calculator

The introduction of special tax allowances, rates and rate bands which interact differently depending on your level and type of income has made the calculation of income tax liability far from straightforward. Our calculator can be used to work out your income tax liability for any of the years 2017/18 to 2019/20, and can be used where you receive any combination of earnings, savings income, dividends and most other types of income. It will also calculate any adjustment required from 6 April 2017 to finance costs relating to letting income.

Using the calculator

After starting the calculator, choose the year for which you wish to make a calculation and enter details of your income and outgoings in the corresponding boxes on the Input screen. Click the Results button to see a summary of your tax position. If you want a detailed breakdown of how your tax liability is worked out, click the Detailed calculations button. The results and detailed calculations can be printed by clicking the Print button.
