The UK tax authority (HMRC) has for the first time published detailed statistics on income from cryptocurrency transactions. The figures are impressive: for the tax period from 2024 to 2025, 240 taxpayers reported profits exceeding £1 million (about $1.35 million). This is not just data—it is a snapshot of a new class of financial elites formed on digital assets.
The total declared profit of these 240 crypto-millionaires reached £717 million ($974 million). Notably, this accounts for more than half of all crypto income recorded in the country during the reporting period. The remaining market participants—17,600 people—showed more modest but still significant results: their crypto asset sales totaled £13.8 billion ($18.8 billion), with taxable profit of £1.38 billion ($1.88 billion), averaging about £78,000 per person.
The gender distribution turned out to be predictably asymmetric: men filed approximately 87% of declarations, while women accounted for only about 13%. This reflects not only differences in income but also in the level of engagement in crypto investments.
What lies behind the HMRC figures
Blockchain data analysts estimate the real scale of Britain's crypto economy to be much higher. Taxable cryptocurrency transactions alone in 2025 are estimated at $19.4 billion. This places the country fourth in the world after the US, Germany, and China. This amount includes $6 billion in profits, $3.3 billion in income, and $10.1 billion in payments.
It is important to understand that these estimates are only a lower bound. The methodology covers six blockchains but does not account for operations on centralized exchanges, certain networks, or types of transactions. The real figures could be significantly higher.
Upcoming tightening of control
From January 2026, the CARF (Cryptoasset Reporting Framework) reporting standard comes into effect. Crypto services will be required to share client data with tax authorities, and HMRC will begin receiving this information from 2027. Violators face a fine of £300 per client.
However, the system is not all-powerful: only 14% of all taxable on-chain transactions worldwide fall under CARF. The remaining 86% consist of operations on decentralized exchanges, direct transfers between users, on-chain income, and payments.
My view: The publication of this data is a signal not only for British investors. It demonstrates that regulators are moving from rhetoric to concrete action. Crypto investors around the world should prepare for the fact that anonymity is becoming a luxury, and tax transparency is the new standard. Those who ignore these trends risk finding themselves under heightened scrutiny from fiscal authorities.
