240 UK Taxpayers Pocket £717 Million from Crypto Gains Exceeding £1 Million

HM Revenue and Customs (HMRC) has released its first dedicated statistics on cryptoasset capital gains, covering the tax year from April 6, 2024, to April 5, 2025. The data reveals that 240 UK taxpayers reported gains exceeding £1 million each from crypto disposals, with this cohort collectively pocketing £717 million.

The numbers behind Britain's crypto wealth boom are striking, with a total of 17,600 people reporting taxable crypto gains, generating £1.38 billion in total. The average gain sits at £78,000 per person, while the total disposal proceeds reached £13.8 billion over the course of the tax year.

The 240 high-earning taxpayers represent just 1.4% of those who reported any crypto gain at all, yet their £717 million slice accounts for roughly half of the total £1.38 billion figure. This data exists because HMRC added a dedicated crypto section to its Self Assessment tax return forms.

HMRC is cracking down on underreporting and omission of crypto gains, issuing over 81,000 warning letters in 2025/26 to taxpayers suspected of non-compliance. These letters are tied to unpaid liabilities stretching back across the 2022 to 2025 market cycle.
