Introduction
Crypto tax-free UK rules can be confusing because the tax-free amount is based on your capital gains, not the total value of cryptocurrency you own. For the 2026/27 tax year, most individuals have a £3,000 Capital Gains Tax Annual Exempt Amount. This allowance applies across qualifying assets, so it is not a separate crypto-only allowance.
Understanding this distinction is important because selling £3,000 worth of crypto does not necessarily mean you have a £3,000 tax-free gain. Your purchase cost, disposal value, allowable costs, losses and other chargeable gains can all affect the calculation.
This guide explains the crypto tax-free UK allowance, taxable crypto disposals, losses, CGT rates and the difference between capital gains and crypto-related income.
What Is the Crypto Tax-Free UK Allowance?
For 2026/27, the main crypto tax-free UK figure is a £3,000 Annual Exempt Amount, covering 6 April 2026 to 5 April 2027. You generally pay Capital Gains Tax when overall taxable gains exceed this allowance after allowable losses and reliefs.
The important distinction is between sale proceeds and profit. If you bought crypto for £8,000 and later disposed of it for £10,000, the simplified gain is £2,000 before relevant fees or adjustments. That gain is below £3,000, assuming no other chargeable gains use the allowance.
How Does Crypto Tax-Free UK Apply to Disposals?
HMRC generally treats disposing of cryptoassets as a Capital Gains Tax event for individuals holding crypto as an investment. A disposal can include:
- Selling crypto for pounds or another fiat currency
- Exchanging one cryptoasset for another
- Using crypto to pay for goods or services
- Giving crypto to another person, subject to applicable rules
Converting Bitcoin into Ethereum can therefore create a gain or loss even though you never withdraw pounds to your bank account. Simply holding cryptocurrency generally does not create a CGT charge. Moving tokens between wallets you beneficially own is also generally not a disposal.
How Do You Calculate Crypto Tax-Free UK Gains?
A simple calculation is:
Disposal value − allowable acquisition cost − allowable costs = gain
Suppose you bought crypto for £5,000 and later disposed of it for £7,500. Your simplified gain is £2,500. If you have no other relevant gains or adjustments, that amount is within the £3,000 Annual Exempt Amount for 2026/27.
If your total gains from crypto and other chargeable assets reach £6,000, the £3,000 allowance leaves £3,000 potentially taxable. The allowance therefore needs to be considered across your wider investment activity.
What About Crypto Tax-Free UK Losses and Income?
Allowable capital losses can reduce gains. For example, £7,000 of gains less £2,000 of allowable losses leaves £5,000 before the Annual Exempt Amount. After the £3,000 allowance, £2,000 would potentially remain taxable.
Crypto received through activities such as staking, mining or lending can instead be subject to Income Tax in relevant circumstances. If you later dispose of those tokens, a separate CGT calculation may apply to a subsequent increase in value.
What Are the Crypto Tax-Free UK CGT Rates?
For gains made from 6 April 2026, individuals generally pay CGT at 18% or 24%, depending on how taxable income and gains interact with the basic-rate band. The £3,000 allowance reduces taxable gains; it does not determine the rate.
There is also no special tax-free withdrawal amount. If a taxable disposal has already occurred, leaving cash on an exchange does not remove the tax liability. Moving taxable proceeds to a bank account is not the test for whether the gain is taxable.
How Can You Track Crypto Tax-Free UK Gains?
Keep records of purchase dates, acquisition costs, disposal values, transaction fees, crypto-to-crypto swaps, transfers between your own wallets, staking or mining income, losses, and exchange histories.
For current rules, check HMRC’s cryptoasset guidance and GOV.UK’s Capital Gains Tax allowances before filing. Tax treatment can depend on the exact transaction and your circumstances.
Conclusion
The main crypto tax-free UK allowance for most individuals in 2026/27 is £3,000 of capital gains. It is not a £3,000 limit on crypto purchases, sales, withdrawals, or portfolio value. Understanding disposals, allowable costs, losses and income treatment is essential when working out your UK tax position.
