Short answer: Capital Gains Tax is due only if your total taxable gains exceed your annual allowance, shown on GOV.UK as £3,000 for individuals. Separately, if you are registered for Self Assessment you report gains on your return when total sale proceeds exceeded £50,000, for 2023 to 2024 onwards, even if no tax is due.
Two separate tests
GOV.UK says you pay Capital Gains Tax on an asset sale if your total taxable gains are above your annual allowance. Work out the gain on each asset, add them, deduct allowable losses. The tax year runs 6 April to 5 April. If gains are under the allowance you pay nothing. But if you are registered for Self Assessment you must also report gains on your return if you sold assets for more than £50,000 in total (2023 to 2024 onwards). The page adds that loss reporting follows different rules.
What counts as a disposal
The overview lists selling, giving away, swapping, and receiving compensation such as an insurance payout. The "work out" page lists personal possessions, shares or investments, UK property, business assets and cryptoassets. This guide covers investments only; we do not cover property.
The allowance
The GOV.UK rates and allowances page (updated 13 April 2026) lists a £3,000 annual exempt amount for individuals for the 2025 to 2026 tax year, and £1,500 for most other trustees.
Rates
For 2025 to 2026 the same page lists 18% and 24% for individuals (not carried interest). Which rate applies depends on your taxable income; check the page for your case.
Fictional example
An investor (made-up) sells shares for £30,000 and other holdings for £25,000 in 2025-26, so proceeds are £55,000. Assume gains of £2,000, under £3,000, so no tax is due on the page's test, but proceeds exceed £50,000 so they report on the return. Our do I need to file guide covers other triggers.
FAQ
Is crypto included? The page lists cryptoassets among assets.
