# UK crypto tax calculator (2026/27)

**A £20,000.00 crypto gain on £40,000 of income costs £3,463.80 in Capital Gains Tax in 2026/27. The first £3,000 is tax-free, £10,270.00 falls in the rest of your basic-rate band at 18.0%, and £6,730.00 is taxed at 24.0%.**

Capital Gains Tax on a crypto sale in the UK for 2026/27: the annual exempt amount, then the basic or higher rate depending on how much of the basic-rate band your income leaves.

## Formula

```text
taxable gain       = gain − annual exempt amount (£3,000.00)
band left          = £37,700.00 − (income − Personal Allowance £12,570.00, tapered above £100,000.00)
tax                = taxable gain within the band left × 18.0% + the rest × 24.0%
```

How long you held the coin does not change UK Capital Gains Tax. The cost is the pooled average cost of your holding, after same-day and 30-day matching, so a single purchase price is exact only if you bought the whole holding at once.
