Capital Gains Tax Calculator

The tax that you have taken from the profit which you have gained from selling or disposing of an asset that has increased in value is called Capital Gains Tax. These assets can include:

  • Any personal possessions that have a total worth of £6,000 or more.
  • Property that you own that is not classed as your main home.
  • Your main home if you have chosen to let it out for business, or is very large.
  • Shares that are not business assets or part of NISA, ISA or PEP.
  • If you have inherited assets you will have to pay Capital Gains Tax when you dispose of it later on.

You are not required to pay any tax on profit that is below your tax-free allowance (called the annual exempt amount). After you have chosen the circumstances that apply to you, you are able to add a number of assets in the table shown below.
