Britain's tax authority, HMRC, has published new data on crypto asset capital gains for the 2024/25 tax year. A total of 240 individuals each reported gains exceeding £1 million, for a combined £717 million — more than half of the £1.38 billion declared by all 17,600 filers. Those filers also recorded £13.8 billion in disposal proceeds. The distribution was highly unequal: 65% of taxpayers had gains below £25,000, but they accounted for just 7% of total gains and 8% of proceeds. The profile of crypto taxpayers skews young and male: 54% were aged 25 to 44, 81% were 54 or under, and men made up 87% of filers while contributing 93% of gains. On compliance, the UK is moving toward the OECD Crypto-Asset Reporting Framework, under which trading service providers must share client data with HMRC from 2027, and non-compliant providers face fines of up to £300 per user. Financial Secretary James Murray stressed that crypto gains are taxable like any other capital gain. Separately, the Treasury plans to defer capital gains tax on DeFi lending and liquidity pool deposits until the underlying assets are actually sold. Gains above the allowance for the 2025/26 tax year must be reported by 31 January 2027.

UK tax authority data shows that 17,600 people reported gains from crypto assets in the 2024-2025 fiscal year, with total declared gains reaching $1.9 billion. Within that group, 240 individuals each reported more than £1 million, or about $1.4 million, in capital gains, for a combined total of about $975 million. James Murray, Exchequer Secretary to the Treasury, said gains from crypto assets should be taxed in the same way as other income. Under the Organisation for Economic Co-operation and Development’s Crypto-Asset Reporting Framework, the UK plans to require crypto-asset service providers to report relevant data. The tax authority had previously sent notices to more than 81,000 people suspected of owing tax.

UK tax data for the 2024 to 2025 tax year shows that 240 people reported capital gains of more than 1 million British pounds each from digital assets, according to figures released by HM Revenue and Customs. Their combined crypto-linked capital gains came to about $975 million. Across the same period, 17,600 people reported digital asset gains totaling $1.9 billion, while total crypto-related asset disposals from sales or trades reached $18.7 billion. The release adds to the UK’s wider push to tighten crypto tax reporting. Financial Secretary to the Treasury and Paymaster General James Murray said gains on cryptoassets are taxable in the same way as other gains and that the government wants people profiting from crypto to understand what they owe. The UK is also moving under the OECD Crypto-Asset Reporting Framework, which will require crypto asset service providers to submit data on users’ gains and losses that may not otherwise have been declared. The figures followed reports that the tax authority had sent more than 81,000 letters to people suspected of underpaying taxes, including crypto investors.

Data from HM Revenue & Customs showed that 240 taxpayers in the UK reported cryptocurrency gains of more than £1 million, or about $1.27 million, during fiscal 2025 covering April to June 2025. The figures point to crypto’s role in personal wealth accumulation in the country while also highlighting the need for tax compliance around digital assets. HMRC is tightening oversight and is requiring crypto asset trading platforms to report user transaction data as part of efforts to combat tax evasion. The figures were cited by Techub, which referenced Crypto Briefing.

The UK’s HM Revenue & Customs, or HMRC, has separately disclosed crypto-asset gains data in personal income tax filings for the first time, according to CoinDesk. In the 2024-2025 tax year, 240 taxpayers reported more than £1 million in crypto capital gains, equivalent to about $1.36 million each at the cited conversion. A total of 17,600 people reported taxable gains from crypto-asset disposals, with aggregate proceeds reaching £1.38 billion, or about $1.87 billion. The average came to roughly £78,000, and nearly 90% of those filers were male. HMRC also said it has begun implementing the Organisation for Economic Co-operation and Development’s Crypto-Asset Reporting Framework, which requires crypto service providers to submit customer data to tax authorities. The agency expects to begin receiving that data from 2027 and plans to use it to cross-check taxpayer filings. Separately, HMRC said compliance and education efforts brought in an additional £168 million in capital gains tax during the 2024-2025 tax year.

The U.K. tax authority has, for the first time, separately disclosed capital gains figures tied to crypto holdings. The data shows that 17,600 people reported a combined $1.87 billion in profits during the 2024-2025 tax year, according to CoinDesk. Within that total, 240 U.K. taxpayers each made more than $1.3 million from their crypto holdings. The figures mark the first standalone release of crypto capital gains data by the country’s tax office and offer a clearer picture of how much taxable profit was reported from digital asset investments over the period.

The UK’s HM Revenue & Customs (HMRC) sent 81,000 warning letters to cryptocurrency investors suspected of unpaid tax over the past 12 months, up 25% from about 65,000 in the previous year. HMRC uses the letters to encourage recipients to disclose unpaid taxes before a formal investigation begins. The UK tax rules can apply to crypto swaps, payments made with tokens, token transfers, lending income and staking income, while residents are generally taxed on worldwide income and gains. HMRC also plans new rules for certain crypto lending and automated market-making arrangements from April 2027, with the changes expected to affect about 700,000 people. Under the cryptoasset reporting framework, service providers will submit 2026 transaction data during a reporting period from Jan. 1 to May 31, 2027, with data exchanges expected across 52 jurisdictions in 2027 and 15 more in 2028.

HM Revenue & Customs has sent about 81,000 warning letters to cryptocurrency holders as part of a recent tax compliance campaign in the UK. Data disclosed through a Freedom of Information request shows the number of such letters has nearly tripled since 2024. The move is intended to remind taxpayers to report and pay capital gains tax tied to crypto assets. The development was cited by Techub News, which referenced BBC News in its brief report. The disclosed figures point to a sharper compliance push by the UK tax authority toward individuals with crypto-related tax obligations, with the campaign focused on reporting and payment requirements rather than any newly announced tax rule in the provided report.
