The UK tax authority (HMRC) has for the first time released detailed statistics on income from digital assets, and the figures are striking. For the 2024–2025 tax period, 240 UK residents declared profits from cryptocurrency transactions exceeding £1 million (about $1.35 million). This is not just dry data — it is a snapshot of a new financial landscape where digital currencies have long ceased to be a niche pursuit.
Where the profits are concentrated
The combined profit of these 240 crypto-millionaires amounted to £717 million ($974 million). Notably, this represents more than half of all documented crypto income in the country for the year. The remaining market participants — 17,600 individuals — showed more modest but still significant results. Their transactions, subject to capital gains tax (CGT), are valued at £13.8 billion ($18.8 billion), with taxable profits reaching £1.38 billion ($1.88 billion), averaging about £78,000 per person.
The gender dynamics are also curious: men filed approximately 87% of all declarations, while women accounted for only about 13%. This points to a persistent imbalance in access to high-risk investments, although it likely also reflects differences in approaches to capital management.
What lies behind the statistics
Analytical firm Chainalysis estimated the total volume of taxable cryptocurrency transactions in the UK for 2025 at $19.4 billion. This is the fourth-largest figure globally, 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 emphasize: the researchers used a conservative methodology, covering only six blockchains and excluding transactions on centralized exchanges, several networks, and certain types of transactions. Thus, the real scale could be significantly higher.
HMRC, for its part, is preparing to tighten oversight. Starting in January 2026, the CARF (Cryptoasset Reporting Framework) reporting standard comes into effect. From 2027, the tax authority will begin receiving data from crypto services about clients, enabling it to identify undeclared income. Violators face a fine of £300 for each client for whom information was not provided.
However, one should not be complacent: the system is not all-powerful. According to Chainalysis estimates, only 14% of all taxable on-chain transactions worldwide fall under CARF. The remaining 86% — operations on decentralized exchanges, direct P2P transfers, on-chain income, and payments — remain outside the regulators' field of vision.
My view: The publication of this statistics is a signal not only for UK investors but for the entire market. Regulators are gradually closing information gaps, and the era of anonymity in cryptocurrencies is coming to an end. Investors should review their tax planning strategies in advance, especially given the upcoming implementation of CARF. Transparency is becoming not just a trend but an inevitable reality.
