HM Revenue and Customs published its first dedicated statistics on cryptoasset capital gains in August 2026, covering the tax year from April 6, 2024, to April 5, 2025. The headline figure is striking: 240 individuals each reported gains exceeding £1 million from crypto disposals, with that cohort collectively pocketing £717 million.
The numbers behind Britain’s crypto wealth boom
Across the entire dataset, 17,600 people reported taxable crypto gains, generating £1.38 billion in total, with the average gain sitting at £78,000 per person. 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 the people 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, which gave the agency a cleaner way to isolate digital asset income from the broader capital gains category.
