Starting January 1, 2026, cryptocurrency platforms operating in the United Kingdom will be legally required to report detailed transaction data on every customer as part of a wide-reaching tax transparency overhaul. The new directive, announced by His Majesty’s Revenue and Customs (HMRC), aims to align the UK with international tax compliance standards and curb tax evasion in the digital asset space.
Under the new rules, crypto firms must collect and submit a full range of user information for each trade or transfer. This includes the user’s legal name, residential address, taxpayer identification number, and the specifics of the transaction, such as the type and amount of cryptocurrency involved. The mandate applies to individuals and legal entities, including companies, trusts, and charities.
Failure to comply or report accurately may result in penalties of up to £300 per user. Although enforcement will begin in 2026, HMRC is urging crypto service providers to begin updating internal systems and data protocols immediately.
The regulation comes as the UK begins implementation of the OECD’s Crypto-Asset Reporting Framework (CARF)—an international agreement designed to facilitate cross-border tax information sharing and tighten oversight of crypto-related income and capital gains.
While the UK has shown interest in supporting blockchain innovation, this initiative underscores its dual priority of financial transparency and consumer protection in an industry long viewed as opaque and underregulated.
Government Pushes Broader Crypto Oversight and Accountability
The new tax reporting requirements are part of a larger effort by UK regulators to bring order to the country’s fast-growing crypto industry. In April, Chancellor Rachel Reeves introduced a draft bill that would regulate crypto exchanges, broker-dealers, and custodians, aiming to reduce fraud, market abuse, and systemic risk.
“Britain is open for business—but closed to fraud, abuse, and instability,” Reeves stated, positioning the bill as a balance between fostering innovation and protecting consumers.
The proposed legislation coincides with rapid growth in crypto adoption. According to a 2024 Financial Conduct Authority survey, 12% of UK adults now own some form of cryptocurrency—tripling the 4% figure from 2021. As retail interest increases, lawmakers are accelerating the push to install guardrails for the maturing market.
UK Takes Separate Path From EU’s MiCA Regulations
As the UK advances its crypto policy framework, it is carving out an independent regulatory identity distinct from the European Union’s Markets in Crypto-Assets (MiCA) regime. Though both systems seek to enhance security and legitimacy, the UK is embracing a more flexible, integration-first model.
A key divergence lies in the treatment of foreign stablecoin issuers. Unlike MiCA, which enforces registration and volume limits to reduce systemic risk, the UK will allow these issuers to operate without mandatory registration or issuance caps—provided they meet basic oversight requirements.
This posture reflects the UK’s strategy to attract international crypto firms by positioning itself as a regulation-forward yet innovation-friendly jurisdiction. Industry analysts suggest the UK’s pragmatic approach could serve as a model for non-EU nations weighing their own digital asset rules.
