Check if I'm over the allowance →What is the CGT allowance?
The Annual Exempt Amount is a tax-free allowance for total chargeable gains across all chargeable assets (crypto, shares, second properties etc.) in a single tax year. For 2024/25 and 2025/26 it is £3,000. Gains within the allowance are not taxed; gains above it are charged at the relevant CGT rate.
How it applies to crypto
Your net gain across all crypto disposals in a tax year is added to gains from any other chargeable assets. If the combined total is £3,000 or less, no CGT is due. If it is more, only the excess is taxed.
Historical allowance amounts
The allowance has reduced significantly in recent years. It was £12,300 for 2022/23, £6,000 for 2023/24, then £3,000 from 2024/25 onwards. Future Budgets may change the figure again — always check the latest HMRC published rates.
Considerations for couples
Each individual UK taxpayer has their own £3,000 allowance. Transfers between spouses or civil partners are typically tax-neutral, which may allow couples to use both allowances. Specific circumstances vary — consider speaking to a qualified accountant.
Frequently asked questions
Can I carry unused allowance to next year?
No. The CGT Annual Exempt Amount cannot be carried forward. If you do not use it in a given tax year, it is lost.
Do I still need to report gains under £3,000?
You may still need to report gains via Self Assessment if your total proceeds from chargeable asset disposals in the tax year exceed £50,000, even if your net gain is under the allowance. The rules on reporting thresholds change — always check the current HMRC guidance.
Does the allowance apply per asset?
No. The £3,000 is a single allowance applied to your total chargeable gains across all assets in the tax year — not per crypto asset, not per exchange.
