UK crypto tax questions.
How much tax do I pay on crypto in the UK?
+
UK crypto capital gains are taxed at 18% (basic rate) or 24% (higher rate) for the 2025/26 tax year. The annual CGT allowance is £3,000 — only gains above this are taxed. Crypto income (staking, mining, airdrops) is taxed as miscellaneous income at your income tax rate.
Does HMRC know about my crypto?
+
Increasingly, yes. HMRC has sent ‘nudge letters’ to crypto holders, has data-sharing agreements with major exchanges, and participates in international information exchange frameworks. Starting 2027, the OECD’s Crypto-Asset Reporting Framework (CARF) will require exchanges to report UK user data directly to HMRC.
What is the 30-day rule for crypto in the UK?
+
HMRC’s 30-day matching rule (also known as the bed and breakfasting rule) means if you sell crypto and repurchase the same token within 30 days, the sale is matched to the repurchase for tax purposes. This effectively prevents tax loss harvesting through quick sell-and-rebuy strategies in the UK.
