UK Crypto Exchanges to Report All User Transactions from 2026

From January 2026, UK crypto exchanges must collect and report detailed user transaction data to tax authorities, aiming to combat tax evasion and align with global standards under the OECD's CARF framework.

Starting January 2026, UK cryptocurrency exchanges will be required to collect and report comprehensive transaction data from their users to tax authorities, following new regulations introduced by HMRC and aligned with the OECD's Cryptoasset Reporting Framework (CARF). These rules mandate the recording of detailed information, including transaction histories, dates, amounts, asset types, and customer identification details such as National Insurance numbers and addresses. The initiative aims to combat tax evasion, increase tax revenue, and ensure that profits from crypto investments are reported similarly to traditional financial assets. The regulations expand oversight to both domestic and cross-border transactions, with the first reports due in 2027. This move reflects the growing significance of digital assets in the UK and aligns with international standards, as most OECD countries are adopting similar measures. While the new rules introduce additional compliance requirements and privacy considerations for both exchanges and users, they are expected to simplify tax reporting for compliant investors and enhance consumer protection.
