The UK tax authority (HMRC) has published detailed statistics on cryptoasset taxation for the first time, and the figures are impressive. For the tax period from 2024 to 2025, 240 residents of the country declared profits from digital currency transactions exceeding £1 million (about $1.35 million). This is the first such report in the agency's history, and it sheds light on the scale of crypto fortunes in the United Kingdom.
The combined profits of these 240 crypto-millionaires amounted to £717 million ($974 million)—more than half of all declared income from cryptocurrencies in the country during that period. For comparison, another 17,600 taxpayers reported profits from digital asset sales subject to capital gains tax (CGT). Their total transaction volume reached £13.8 billion ($18.8 billion), with taxable profits of £1.38 billion ($1.88 billion), averaging about £78,000 per person.
Gender imbalance and concentration of capital
Analysis of the declarations reveals a pronounced gender asymmetry: men filed approximately 87% of all declarations, while women accounted for only about 13%. This indicates that crypto investing in Britain remains a predominantly "male" domain, which is, however, also characteristic of the global digital asset market.
It is worth noting that the tax burden on crypto investors is no different from traditional financial instruments. As Treasury Financial Secretary James Murray emphasizes, taxes on cryptoasset profits are paid in the same way as on any other income. This is an important signal for those who still believe that digital currencies exist outside the legal framework.
On-chain analytics: the real scale of the market
An independent assessment from the analytics firm Chainalysis paints an even larger picture. According to their calculations, the volume of taxable cryptocurrency transactions in the UK for 2025 reached $19.4 billion. This is the fourth-highest figure in the world after the US, Germany, and China. This amount included $6 billion in profits, $3.3 billion in income, and $10.1 billion in payments.
However, it is important to understand: Chainalysis's methodology is conservative, and their estimate is only a lower bound. The analysis covers six blockchains but does not account for transactions on centralized exchanges and a number of other networks, meaning the real figures could be significantly higher.
A new era of transparency: what awaits investors
HMRC is already preparing the ground for stricter oversight. From January 2026, the CARF (Cryptoasset Reporting Framework) reporting standard comes into effect, which will require crypto services to transmit client data to tax authorities. HMRC will begin receiving this data from 2027. Violators face fines of £300 per client.
Nevertheless, the system is not comprehensive. According to Chainalysis, CARF covers only 14% of all taxable on-chain transactions worldwide. The remaining 86% consist of operations on decentralized exchanges, direct P2P transfers, and other types of activity that remain outside the regulators' view.
My take: The publication of this statistics is a clear signal that the era of anonymity in cryptocurrencies is coming to an end. British authorities are actively building infrastructure for total tax control, and investors should prepare in advance for the new reality of transparency. The only question is how effectively CARF will be able to cover the decentralized segment of the market, which continues to grow.
