| Annual exempt amount | £3,000 |

In short: take the sale price, deduct what you paid and allowable costs, deduct losses and the £3,000 annual exempt amount, then tax the rest at 18% if it falls within your unused basic rate band and 24% above it.
Tom earns £30,000 and sells shares for a £20,000 gain. After the £3,000 exemption, £17,000 is chargeable. His unused basic rate band is £20,270, so all of it is taxed at 18%: £3,060.
If you sell a UK home that was not your main residence, you must usually report and pay within 60 days of completion, then include it on your tax return. Private Residence Relief can reduce or remove the gain on a former home.
Our Capital Gains Tax service handles both returns. For crypto, see crypto tax returns. More on our tax calculators page.
