HM Revenue and Customs (HMRC) has published its first official statistics on taxable cryptoasset gains, revealing that 240 people declared more than £1 million in capital gains from cryptoassets during the 2024 to 2025 tax year. This group collectively reported £717 million in cryptoasset gains.
Across all taxpayers, 17,600 individuals made Capital Gains Tax-liable disposals of cryptoassets in the same period, reporting total gains of £1.38 billion. The average gain per individual was £78,000. Around 87% of individuals reporting cryptoasset gains were male, and approximately 13% were female.
The data follows the introduction of a dedicated section for cryptoasset capital gains on the Self Assessment return. From 2027, HMRC will start receiving customer information from cryptoasset service providers, as part of the international Cryptoasset Reporting Framework (CARF) which the UK began implementing in January 2026.
James Murray MP, Financial Secretary to the Treasury, stated that taxes are due on cryptoasset gains like any other gains, emphasising the government's aim to close the tax gap. John-Paul Marks, HMRC’s Permanent Secretary, highlighted the importance for individuals to check their tax obligations as new international reporting rules come into force.
