Capital Gains Tax is a tax you pay on your profits. You declare anything you’ve earned from selling an asset (over a certain threshold) via a tax return. You’ll then need to file and pay your Capital Gains Tax bill by 31st January each tax year.
The rate of CGT that you pay each year depends on the type of asset you’ve sold and how much you earn overall.
Use our Capital Gains Tax calculator to work out what tax you owe on your investment profits. Capital Gains Tax is basically a tax that you’re charged on money you make from selling an asset. When we say asset, this can mean any of the following that generate taxable gains:
As you can see from using the calculator, you pay different rates depending on what you’re selling. Check out the basic Capital Gains Tax formula here 👇
| Type of asset | Basic rate band
(income < £50,270) |
Higher rate band
(income > £50,270) |
| Shares | 18% | 24% |
| Residential property | 18% | 24% |
| Cryptocurrency | 18% | 24% |
| Other | 18% | 24% |
After selling an asset, you only owe Capital Gains Tax on profits above £3,000 in the 2024/25 tax year. Anything less than that is tax-free. When you earn more than £3,000 during a tax year, this is taxable income which you will need to declare to HMRC and file a tax return. Make sure you do this by 31st January the tax year after you profit.

No. If you’re selling your main home, you don’t owe CGT. You only pay capital gains tax on property if you’re operating a buy-to-let business or have a second home that you’re selling.
You also don’t need to worry about paying any CGT on your rental income. You’ll owe Income Tax on this and CGT at the point at which you sell up (if you’re not also living in the house). Read more about rental income tax via our guides.
Reducing the CGT you owe may be tricky. There’s no tax credit or tax relief associated with it, however you can claim the Capital Gains Tax allowance to reduce your tax liability. Every tax year, you can earn up to £3,000 tax-free (previously £6,000) in profit. Anything less than this means you won’t have to file a tax return.
Filing with TaxScouts is just easier. Not only that, but we’re friendlier, jargon-free and have expert accountants on our side.
