What is Capital Gains Tax?

Capital Gains Tax, often called CGT, is a tax on the profit you make when you sell or dispose of an asset that has gone up in value. In simple terms, it is charged on the gain, not on the total amount you receive.

It can apply to a range of assets, including property, shares, and valuable personal possessions in some cases. If you sell an asset for more than you paid for it, the difference may count as a capital gain.

When CGT applies

CGT is usually due when you sell an asset, give it away, exchange it, or otherwise dispose of it. A disposal can also include receiving compensation for an asset, depending on the circumstances.

For many people in the UK, CGT is most commonly associated with second homes, buy-to-let properties, and investments such as shares. Your main home is often exempt, but there are important rules and exceptions.

How the tax is worked out

To calculate CGT, you normally work out the gain by subtracting what you paid for the asset, plus certain allowable costs, from the amount you received. Allowable costs can include things like purchase fees, legal fees, and improvement costs.

After that, you may be able to use your annual CGT allowance, known as the Annual Exempt Amount. Any gain above this allowance is taxed at the relevant rate, depending on the type of asset and your income tax band.

CGT rates in the UK

CGT rates are different from income tax rates. The rate you pay depends on whether the gain is from residential property or from other chargeable assets such as shares.

For most other assets, the rate is usually lower if you are a basic rate taxpayer and higher if you are a higher or additional rate taxpayer. Residential property gains are generally taxed at separate rates, which are higher than those for most other assets.

Who needs to pay it

You may need to pay CGT if your total gains in a tax year go over the exempt amount. This means not everyone who sells an asset will owe tax.

Some people may also be able to claim reliefs or exemptions, which can reduce or remove the amount due. Rules can vary depending on the asset and your personal situation.

Why it matters

CGT can have a significant effect on the real profit you make from selling an asset. That is why it is important to think about it before you dispose of anything that has risen in value.

Good records can help you work out your gain accurately and avoid paying too much tax. If your situation is complex, it may be worth checking the latest HMRC guidance or speaking to a tax professional.
