Understanding Crypto Tax Rates in the UK: Capital Gains Explained

The UK has established a framework for taxing cryptocurrency transactions, particularly capital gains. As of 2025, the UK tax system treats cryptocurrency as an asset, and gains from its sale or exchange are subject to capital gains tax (CGT). This article explains the crypto tax rate in the UK, factors affecting capital gains, and how to calculate your tax liability.

## How the UK Tax System Treats Cryptocurrency
The UK’s HM Revenue and Customs (HMRC) classifies cryptocurrency as an asset, meaning it is subject to capital gains tax when sold or exchanged. Unlike traditional assets, cryptocurrency is not inherently taxable, but gains from its sale or exchange are. The tax rate for capital gains in the UK is 18% for most individuals, with a 10% rate applicable to gains from the sale of residential property. However, cryptocurrency is treated as a ‘collectable’ asset, so it falls under the general capital gains tax rules.

## Factors Affecting Crypto Tax Rates in the UK
Several factors influence the tax rate for cryptocurrency transactions in the UK:
1. **Type of Transaction**: Selling cryptocurrency generates a capital gain, while exchanging it for another cryptocurrency may not. However, HMRC considers exchanges as sales, so they are taxable.
2. **Holding Period**: If you hold cryptocurrency for over 12 months, gains are taxed at the lower 10% rate. Short-term gains (held for less than 12 months) are taxed at 18%.
3. **Nature of the Transaction**: Gains from selling cryptocurrency are taxed at 18%, while gains from exchanging it for another cryptocurrency are taxed at 10% if the holding period is over 12 months.
4. **Exemptions**: Certain transactions, such as those involving a business or a cryptocurrency wallet, may qualify for exemptions or reduced rates.

## Calculating Your Crypto Tax Liability in the UK
To calculate your capital gains tax liability from cryptocurrency in the UK, follow these steps:
1. **Determine the Cost Basis**: This is the original value of the cryptocurrency when you purchased it. For example, if you bought 1 Bitcoin for $50,000, the cost basis is $50,000.
2. **Calculate the Sale Price**: This is the amount you received when you sold the cryptocurrency. For example, if you sold 1 Bitcoin for $60,000, the sale price is $60,000.
3. **Compute the Capital Gain**: Subtract the cost basis from the sale price. $$text{Capital Gain} = text{Sale Price} – text{Cost Basis}$$
4. **Apply the Tax Rate**: Multiply the capital gain by the applicable tax rate (18% or 10%). For example, a $10,000 gain taxed at 18% would result in a $1,800 tax liability.
5. **Report to HMRC**: Use the Self-Assessment tax return to report your gains and pay any owed taxes.
