Reading the result

Enter gains after acquisition and disposal costs, not sale proceeds. Losses here are current-year allowable losses; carried-forward loss rules differ.

How it works

We subtract entered allowable current-year losses and the annual exemption, then allocate gains to the unused UK basic-rate band and the higher CGT rate.

Frequently asked questions

Does this include a property sale?

Ordinary taxable residential gains use the same rates in this model, but private residence relief must already have been deducted.

Does Scotland use a different CGT rate?

No. UK CGT bands apply; Scottish earned-income tax bands do not replace them.
