What it means

In the UK, Capital Gains Tax can apply when you sell or otherwise dispose of something you own, such as certain investments or property, for more than it cost you. It is generally the gain, rather than the full selling price, that matters. Not every asset or gain is taxable: there are exemptions, allowances and rules about losses and costs. A rise in an asset's value alone does not normally mean you have sold it and owe this tax.

Example

You buy shares for £1,000 and later sell them for £1,300. Before any relevant costs or reliefs, the gain is £300, not £1,300. Whether any Capital Gains Tax is actually due depends on the rules that apply to you.

Why it matters

Confusing the sale price with the gain can make a potential tax bill sound much larger than the amount being considered for tax.
