All inhabitants of the United Kingdom are required to pay a personal income tax every year. This income tax is based on your total income for the year you are filing. Calculating how much you owe in income tax is very simple once you know the tax brackets and tax percentages that accompany those brackets. For the United Kingdom, the tax brackets are 10 per cent of 0- 2,440 pounds, 20 per cent of 2,440- 37,400 pounds and 40 per cent of more than 37,400 pounds.

    Add up your total income for the year you are filing personal income tax in the United Kingdom. It is important to do this accurately in order to identify the tax bracket you fall under.

  2. 2

    Identify which tax bracket you fall into. For example, if you made 100,000 pounds, you would fall into the 40 per cent tax bracket.

  3. 3

    Multiply your total income by the tax percentage of your bracket. Using the example above, you would owe 40,000 pounds in income tax (.4 x 100,000).
