United Kingdom Capital Gains Tax Calculator

The low income bracket gets 18%; middle and high both get 24%. There is no third setting, because the engine treats middle and high identically. On the page's £80,000 gain, after the £3,000 annual exempt amount leaves £77,000 taxable, that is £13,860 at 18% and £18,480 at 24%. The £4,620 gap is decided entirely by which bracket you select.

It is subtracted once from the gain before any rate is applied, and it is capped at the gain itself. That makes it worth £720 to a 24% taxpayer and £540 at 18%. A gain of £3,000 or less leaves nothing taxable and produces no tax at all. Because the deduction comes first, the effective rate on the page's £80,000 gain is 23.10% rather than 24%.

Not since 30 October 2024. Basic-rate taxpayers pay 18% and higher or additional-rate taxpayers pay 24% on all asset types, residential property included, and the calculator reflects that. Switching the asset control between General asset and Residential property returns the same tax and the same net proceeds. The older split rates for non-residential assets are gone from the model.

No. The UK branch of the engine reads the income bracket but ignores the holding period, so a gain marked short-term and the same gain marked long-term produce identical output. The switch exists because other countries in this calculator use it. Read the UK result as one figure per bracket rather than as a holding-period comparison.

Costs of acquisition and disposal, capital losses set against the gain in-year or brought forward, and any relief tied to the asset or the seller. Only the purchase price you enter reduces the sale price. If the sale price is below the purchase price the gain is recorded as zero, and the model neither banks that loss nor carries it forward.

When your gain crosses the basic-rate boundary. The calculator asks for a bracket, not an income figure, so it cannot tax part of a gain at 18% and the rest at 24%; it applies one rate to the whole amount. On the page's £77,000 taxable gain the two answers are £13,860 and £18,480, and a straddling case falls somewhere between them.
