Capital Gains Tax is a UK tax applied to the profit (the "gain") you make when you sell or dispose of an asset that has increased in value. It is strictly the profit you make that is taxed, not the total amount of money you received from the sale.
How to calculate Capital Gains Tax: Deduct your original purchase price and any allowable selling/improvement costs from your final sale price. If your total gains for the tax year exceed the Annual Exempt Amount (£3,000 for 2026/27), you pay tax on the remainder. The rate depends on your income tax band: 18% where the gain falls within the basic rate band and 24% above it. Since 30 October 2024 the same rates apply to shares and business assets as to residential property — there is no longer a lower rate for non-property gains.
Business asset sales may qualify for Business Asset Disposal Relief (resulting in a flat 10% rate). Structuring your investments through an expert Accountant drastically minimizes CGT exposure and ensures you utilize all available transfer allowances.
These figures use 2026/27 rates for England and Northern Ireland and only the details you have typed in. Scotland and Wales set some of their own rates, and allowances, reliefs, other income and your tax code can all change the answer considerably.
We check the rates behind these tools against GOV.UK and believe them correct to the best of our knowledge, but we cannot guarantee the result is accurate for your circumstances and do not accept responsibility for decisions made on it. Please do not file a return or commit to anything on this figure alone — do your own research, and speak to a qualified accountant who can see your full position.
