Understanding UK Capital Gains Tax
Capital Gains Tax (CGT) is a tax on the profit you make when you sell or dispose of an asset that has increased in value. It is the gain you make that is taxed, not the total amount of money you receive. The amount of tax you pay depends on the asset type, the size of your gain, and your personal income tax band. This Calculator Site tool helps you estimate your potential liability.
The UK tax system provides an Annual Exempt Amount, which is a tax-free allowance for capital gains. For the 2026/27 tax year, this is £3,000. You only start paying CGT on gains above this threshold. To understand how your salary impacts your tax situation, you can use our Take-Home Pay Calculator.
Tip: Your Income Tax Band is Key
Your CGT rate is not fixed; it is determined by your Income Tax band. If your taxable income (including your capital gains) keeps you within the basic rate band, you pay a lower rate of CGT. If the gain pushes you into the higher rate band, that portion of the gain is taxed at a higher CGT rate. It is a crucial interaction between your income and your investments.
Key CGT Rates & Allowances (2026/27)
Different assets are taxed at different rates. Gains from residential property have their own specific rates, which are higher than those for other assets like shares or business assets. Understanding these differences is vital for accurate tax planning. For property-specific taxes, see the Stamp Duty Calculator.
