- HMRC issued nearly 65,000 crypto tax warning letters in 2024–25, doubling last year’s total.
- The UK tax authority now accesses exchange data and will gain global reporting under the OECD framework by 2026.
- UK crypto ownership has reached seven million adults, intensifying HMRC’s focus on accurate tax reporting.
HM Revenue & Customs (HMRC) has boosted its search for unpaid cryptocurrency taxes, issuing nearly 65,000 warning letters to investors during the 2024–25 tax year. The number has more than doubled from the previous year, reflecting an expanded effort to enforce tax compliance as digital asset ownership continues to rise across the United Kingdom.
Growing Focus on Crypto Tax Compliance
Confirmed via an X post by Fomos News, the letters, often referred to as “nudge letters,” aim to prompt taxpayers to review and correct their filings before formal investigations begin. HMRC has now sent over 100,000 such notices within four years, underscoring its increasing attention on digital asset reporting.
Officials confirmed that the initiative is designed to improve voluntary compliance and prevent tax avoidance linked to crypto transactions. HMRC’s monitoring capabilities have strengthened through new data-sharing agreements with leading cryptocurrency exchanges.
The agency now receives direct transaction information, giving it greater visibility into investors’ trading activities. By 2026, HMRC is expected to gain automatic access to global exchange data under the Organization for Economic Co-operation and Development’s Crypto-Assets Reporting Framework. This system will enable tax authorities worldwide to track cross-border crypto activity more efficiently.
Complex Rules Challenge Many Investors
Tax specialists noted that many individuals may be unaware their crypto trades trigger taxable events. According to UHY Hacker Young partner Neela Chauhan, even exchanging one digital coin for another can result in a capital gains liability. The firm obtained HMRC’s latest figures through a Freedom of Information request, confirming the rising number of taxpayers receiving compliance notices.
Recent assessments from the Financial Conduct Authority tell that seven million adults in the UK now hold cryptocurrency. This marks a notable increase from five million in 2022 and just over two million in 2021. The surge in ownership has intensified HMRC’s need for stronger oversight to ensure all taxable gains are accurately reported.Other countries are also strengthening their oversight of crypto-related tax obligations. In the United States, lawmakers are reviewing proposals to exempt minor digital transactions under $300 and clarify the taxation of staking rewards. Meanwhile, South Korea’s National Tax Service confirmed that it could seize crypto assets stored in cold wallets if connected to unpaid taxes.
