UK tax data show a relatively small group of investors accounted for a large share of reported cryptocurrency gains in the 2024-25 tax year. According to the government, 240 people each declared more than $1.4 million in crypto-related capital gains, with their combined gains reaching about $975 million.
The figures came from HM Revenue & Customs data covering a broader pool of roughly 17,600 individuals who reported digital asset gains during the same period. Together, those taxpayers declared about $1.9 billion in gains and $18.7 billion in crypto “disposals,” a category that includes selling or trading assets.
What the tax data showed
The government’s numbers suggest that reported crypto profits were concentrated among a limited number of high-gain taxpayers. While 17,600 people disclosed gains tied to digital assets in the 2024-25 tax year, 240 of them were responsible for roughly half of the total amount reported through large individual gains.
In the same dataset, HMRC recorded $18.7 billion in disposals. That figure refers to transactions such as selling or exchanging cryptoassets, which can trigger tax reporting obligations even when the final taxable gain is much smaller than the value of the assets disposed of.
Government message on crypto tax
The release was accompanied by a warning from the Treasury that crypto gains are taxed in the same way as other capital gains. James Murray, Financial Secretary to the UK Treasury and Paymaster General, said taxes are due on cryptoasset gains and that the government wants people profiting from crypto to understand what they owe.
The statement fits into a broader compliance push by UK authorities, which have been increasing attention on digital asset reporting and taxpayer awareness rather than treating crypto as outside the normal tax system.
Enforcement efforts are already expanding
The publication of the figures followed reports that HMRC had sent more than 81,000 letters to people suspected of underpaying tax, as part of efforts aimed at crypto investors. The letters indicate that enforcement is not limited to voluntary disclosure and that authorities are actively comparing available information with what taxpayers have reported.
The article does not say how many of those cases will result in additional tax assessments, but the scale of the outreach shows the government is stepping up scrutiny as crypto activity becomes more visible to tax authorities.
New reporting rules are the next step
The UK is also preparing to implement reporting requirements for cryptoasset service providers under the OECD’s Crypto-Asset Reporting Framework. Under that framework, service providers will be expected to submit data on users’ crypto gains and losses, including activity that might not otherwise have been declared by taxpayers.
The source article said taxable onchain crypto activity expected under the OECD framework totaled $457 billion globally in 2025. For the UK, the next confirmed development is the move toward provider-based reporting, which should give tax authorities more direct information on digital asset transactions and make non-disclosure harder to sustain.
