The U.K.’s HMRC mandated crypto exchanges collect full user data by 2026. This aims to curb tax evasion, aligning with OECD CARF.
The U.K.’s HMRC has issued new rules. These require crypto exchanges operating in the country to collect full transaction data. This applies to all U.K. users. This starts January 1, 2026. They have to submit the information to HMRC in 2027. This is so that the tax authority can cross-check returns. It also seeks to reduce tax evasion through crypto. The framework is in line with the Crypto-Asset Reporting Framework (CARF) by the Organization for Economic Cooperation and Development (OECD). This framework is already being followed in the EU, Canada, Australia, Japan, and South Korea.
HMRC Mandates Full Crypto Transaction Data Collection
With platforms due to keep a record of this information from January 1, 2026, ahead of sharing it with HMRC the year after, the tax office will be able to cross-check tax returns against the data they’ve received, Seb Maley, CEO of tax insurance provider Qdos, told FT. British tax experts, this gives crypto users, traders, and investors until the end of 2026. This is to get their digital asset house in order. This will help them to avoid sanctions.
Firms have to gather personal information. These include a user’s full name, address, date of birth, country of residence, and tax identification number.

The impact on users is great. This regulation means that crypto activity will be more visible to HMRC. For HMRC, the data will be used to verify tax returns. It will also look for non-compliance. This applies to activities such as selling, exchanging, or gifting cryptoassets.
Penalties for non-compliance include fines. This is true for both service providers and users. Users who do not give accurate information may also be penalized.
CARF Alignment Strengthens International Crypto Tax Oversight
International exchange is an important feature. Under CARF, data will be exchanged between other compliant jurisdictions automatically. This means the use of an overseas crypto platform will not prevent data from being shared with HMRC.
While the reporting framework is not due until 2026, the underlying tax obligations are already in place. Crypto users are advised to check their transaction records. They should make sure that they report all gains and income correctly in their self-assessment tax returns.
This move by the U.K. government highlights the fact that a change is occurring globally. Regulatory bodies are paying a lot more attention to compliance with crypto taxes. The correspondence with the CARF of the Organization for Economic Cooperation and Development (OECD) shows a concerted international effort. This is to further the cause of transparency.
The rigorous requirements for data collection help ensure complete oversight. Personal and transactional information will give HMRC a clear picture. This will be beneficial in identifying undeclared crypto gains. It will also reduce illicit activities.
