For the first time in its history of observations, the UK's tax authority (HMRC) has released detailed statistics on cryptocurrency income. The figures are impressive: for the tax period from 2024 to 2025, 240 residents of the country declared profits from digital asset transactions exceeding £1 million (about $1.35 million). This is not just dry data, but a marker of market maturity and growing tax discipline.
The combined profit of these crypto-millionaires amounted to £717 million ($974 million). For context: this is more than half of all declared crypto-asset income in the country for that period. The remaining market participants — 17,600 people who realized profits from selling cryptocurrencies — collectively showed transactions totaling £13.8 billion ($18.8 billion). At the same time, the taxable base for these operations reached £1.38 billion ($1.88 billion), averaging about £78,000 per person.
Gender imbalance and investor profile
Analysis of the declarations revealed a pronounced gender asymmetry: approximately 87% of reports were filed by men, while women accounted for only about 13%. This indirectly confirms the thesis that active trading in crypto-assets remains predominantly a male domain, although the share of women in long-term investments may be higher.
Market scale and its real volume
Estimates from the analytical company Chainalysis, which specializes in blockchain analytics, show that the total volume of taxable cryptocurrency transactions in the UK for 2025 amounted to $19.4 billion. This places the country fourth in the world after the USA, Germany, and China. This figure includes $6 billion in profits, $3.3 billion in income, and $10.1 billion in payments. It is important to emphasize: analysts used a conservative methodology, so these figures represent only the lower bound. The calculation covered six blockchains but did not account for operations on centralized exchanges, several networks, or certain types of transactions.
New rules of the game: CARF and penalties
From January 2026, the CARF (Cryptoasset Reporting Framework) reporting standard comes into effect. From that point, crypto-asset service providers are required to transmit client data to tax authorities. HMRC will begin receiving this information from 2027, which will allow it to identify undeclared income. A fine of £300 per client is stipulated for violating the requirements.
However, the system is not all-powerful. According to Chainalysis, only 14% of all taxable on-chain transactions worldwide fall under CARF. The remaining 86% — operations on decentralized exchanges, direct transfers between users, on-chain income, and payments — remain outside the regulators' field of vision.
My view: The publication of this data is a signal not only for British investors but for the entire market. HMRC demonstrates that cryptocurrency is no longer a "gray area," and transparency is becoming inevitable. However, the 86% of "invisible" transactions remind us: the race between regulators and technology continues, and for now, decentralized finance retains the advantage in anonymity.
