Hi,
To calculate a capital gains liability, you first have to calculate the income tax liability. If all of the basic rate band of income tax is used up in the income tax calculation, there is nothing left of the basic rate band to allocate to the lower rate capital gains calculation. If there is an amout of the basic rate band not used in the income tax calculation, then this amount of unused BR band can be utilised against capital gains, by being applied to the lower rate band.
For residential property and land the lower rate is 18% and the upper rate 28%.
For other types of capital gain, the lower rate is 10% and the upper rate 20%.
There is a calculator below, which can be used to calculate the capital gain arising from a disposal of UK property and land.

You can save a copy of the calculation to your computer and move to the next screen to create a capital gains account at:
Report and pay your Capital Gains Tax
You can use this account to report and pay your capital gains tax from residential property and land. You should do so within 60 days of the completion date to avoid late penalties.
If you have disposed of other kinds of assets, such as personal possessions you can report and pay the capital gains tax at:
