Every billionaire linked to the UK has been assigned a personal compliance manager by His Majesty’s Revenue and Customs. This roster now extends past individuals who submit a British tax return.
Although the tax agency has not disclosed any names or the total head count, it stated that these figures will be released in an upcoming wealthy compliance plan scheduled for later this year.
Watchdogs told HMRC it Could not Count its Own Billionaires
According to a National Audit Office finding from last year, HMRC had previously assigned compliance managers to roughly 15,000 affluent taxpayers. This represented about 2% of that demographic, with assignments determined by risk instead of net worth alone.
“HMRC cannot identify how much tax is paid by UK billionaires, despite the relatively small number of individuals and significant sums of money involved,” the cross-party Public Accounts Committee noted in its report.
To compile the new roster, HMRC drew from its internal database, public sources like rich lists, and information provided by foreign governments. Each dedicated manager maps an individual directly to their associated trusts, corporations, and other business structures.
Crypto is not the Target, but the Data is Arriving
While HMRC has not clarified if any cryptocurrency billionaires are included, fortunes amassed through digital tokens are treated identically to real estate wealth once an individual crosses the financial threshold.
Visibility is what will shift moving forward. The Cryptoasset Reporting Framework was enacted in Britain this January, establishing an international mandate that requires trading platforms to disclose customer information to tax regulators. HMRC will begin receiving this exchange data under the UK rules in 2027.
The department already captures a portion of this activity. Official figures indicate that for the 2024–25 period, 17,600 taxpayers reported £1.38 billion in gains from cryptoassets. Within that group, 240 crypto millionaires were responsible for £717 million.
During the same timeframe, HMRC issued 65,000 warning letters to suspected digital asset traders, a significant increase from the previous 27,700 notices.
The exact dimensions of the billionaire registry will be made public in the compliance strategy due prior to the close of 2026, while the exchange data feeds will arrive a year afterward.
