UK Tax Authority Mandates Crypto Platforms to Report Transactions Under New Framework

London, UK – In a significant move to enhance tax compliance and transparency in the burgeoning digital asset market, His Majesty’s Revenue & Customs (HMRC) has announced that all cryptocurrency platforms operating in the United Kingdom will be required to report users’ domestic and cross-border transactions under the Crypto Asset Reporting Framework (CARF), set to take effect in 2027.

This new directive aims to tighten the grip on tax avoidance by ensuring that crypto service providers perform due diligence, verify user identities, and annually report detailed transaction information. While CARF primarily focuses on cross-border transactions, the UK’s expansion of the framework to include domestic transfers marks a pivotal shift in regulatory oversight, preventing cryptocurrencies from becoming an “off-CRS” asset class that escapes scrutiny.

A Unified Approach to Crypto Taxation

The CARF initiative, developed by the Organization for Economic Co-operation and Development (OECD), is already being implemented in several countries, including the European Union, Canada, Australia, Japan, and South Korea. By aligning with these nations, the UK aims to streamline reporting processes for crypto companies and provide tax authorities with comprehensive data to identify non-compliance.

Starting in 2026, crypto platforms classified as “Reporting Cryptoasset Service Providers” will be required to collect and submit transaction data directly to the HMRC. Failure to comply with this reporting order could result in fines and sanctions, placing the onus on crypto users, traders, and investors to ensure their digital asset affairs are in order before the deadline.

“No Gain, No Pain” Proposal for DeFi Users

In a complementary move, the UK government has proposed a new tax framework dubbed “no gain, no pain,” which seeks to exempt users of decentralized finance (DeFi) lending and liquidity pool platforms from capital gains tax until the underlying crypto is sold. Currently, British crypto users face capital gains tax rates ranging from 18% to 32% upon depositing funds into DeFi protocols, regardless of the purpose.

Stani Kulechov, CEO of the decentralized lending protocol Aave, hailed the proposal as a “major win” for DeFi users, allowing them to borrow stablecoins against their crypto collateral without immediate tax liabilities. The HMRC is currently in discussions with industry stakeholders to evaluate the merits of this approach and potential legislative changes.

Global Trends in Crypto Taxation

As the crypto market continues to integrate into mainstream finance, governments worldwide are revising their tax codes to better capture digital asset activity. South Korea has taken a hardline approach, announcing plans to seize crypto assets held in cold wallets if taxpayers are suspected of hiding digital assets. Meanwhile, Spain is considering a staggering 47% top tax rate on crypto capital gains, while Switzerland has set a 2027 deadline for implementing CARF reporting rules.

In the United States, lawmakers are exploring innovative proposals, such as the Bitcoin for America Act, which would allow taxpayers to fulfill federal tax obligations in Bitcoin and exempt these transactions from capital gains taxes.

Conclusion

As the UK prepares for the rollout of CARF and the “no gain, no pain” proposal, crypto users must brace for a new era of regulatory oversight. With the deadline for compliance looming, the onus is on the crypto community to adapt to these changes and ensure they remain on the right side of the law. The evolving landscape of crypto taxation underscores the growing recognition of digital assets in the global financial system and the need for transparent, equitable tax practices.
