240 U.K. Crypto Millionaires Accounted for More Than Half of Taxable Crypto Gains
Britain’s first official tax breakdown for crypto shows gains were concentrated in a small group of investors during the 2024-25 tax year. HM Revenue & Customs said 240 people each reported more than £1 million in cryptoasset capital gains, totaling £717 million. Although that group represented less than 2% of the 17,600 individuals who declared crypto disposals, it accounted for more than half of both the £1.38 billion in gains and the £13.8 billion in disposal proceeds. At the lower end of the spectrum, 65% of crypto taxpayers reported gains below £25,000, contributing 7% of total gains and 8% of proceeds. HMRC said the figures were published separately for the first time after the Self Assessment return added a dedicated section for cryptoasset disposals. The tax authority’s data also points to a distinct demographic profile: crypto taxpayers skew younger and more heavily male than the wider capital gains population. The U.K. has also started implementing the OECD’s Cryptoasset Reporting Framework, with HMRC due to begin receiving customer data from service providers in 2027. Separately, the Treasury plans to defer capital gains tax on DeFi lending and liquidity pool deposits until assets are actually disposed of.
