UK Crypto Investors Declare £1.38B in Gains, but Half Comes from Just 240

HM Revenue & Customs (HMRC) has published data on UK crypto investors' reported gains, showing £1.38 billion in declared profits. The figures are from a dedicated crypto section added to Self Assessment returns and cover the 2024 to 2025 tax year.

Of those who reported gains, 240 individuals accounted for more than half of the total at £717 million each. This means that just 0.6% of investors made up 53% of the reported gains.

The data marks a significant milestone in crypto tax reporting as it provides HMRC with a baseline to compare against future reports from providers under the OECD's Cryptoasset Reporting Framework (CARF).

Under CARF, crypto businesses will begin collecting customer and transaction information in January 2026. HMRC expects to start receiving provider reports in 2027, which will give it a separate dataset to identify discrepancies between reported gains and activity recorded by platforms.
