What is Capital Gains Tax?

Capital Gains Tax (CGT) can be due when you sell something that’s increased in value, or you transfer it outside of your estate, e.g. to another person or into a trust. It can apply when selling or transferring lots of different assets, for example shares or property. It is only any gain that may be subject to tax, not the total value of the asset.
