HM Revenue & Customs has released its first detailed breakdown of taxable crypto gains in the UK. The data shows that 17,600 people declared a combined £1.38 billion in crypto gains. A group of 240 crypto millionaires was responsible for more than half of the total amount reported. Most of those declaring gains were younger than 55, while men represented 87% of all taxpayers included in the breakdown. The figures provide an initial view of the concentration and demographic profile of taxable crypto gains reported to the UK tax authority. The data was highlighted by Decrypt in a report published on August 28, 2026.
