UK Reveals 240 Crypto Millionaires Amid Tightening Tax Enforcement

The United Kingdom’s tax authority disclosed that 240 individuals each reported more than 1 million British pounds, roughly $1.4 million, in capital gains from crypto during the 2024 to 2025 tax year. Combined, this group reported nearly $975 million in gains. Across a broader pool of 17,600 people who declared digital asset gains during the same period, total reported profits reached $1.9 billion, with $18.7 billion coming from asset sales and trades.

Officials Push for Greater Tax Compliance

A senior UK Treasury official emphasized that crypto gains are subject to the same tax obligations as any other capital gains, stressing the importance of ensuring crypto investors understand their tax responsibilities. This data release follows separate reports that the UK’s tax agency has already sent more than 81,000 letters to individuals suspected of underreporting crypto-related income, signaling a broader crackdown on unpaid taxes tied to digital assets.

Part of a Larger Global Reporting Push

This disclosure comes as international efforts to track crypto tax compliance continue expanding. Under a global reporting framework developed by the OECD, worldwide onchain crypto activity considered potentially taxable reached an estimated $457 billion in 2025. As part of this framework, the UK will soon require crypto service providers to report gains and losses data directly, closing gaps where individual taxpayers might otherwise fail to disclose profits on their own.
