UK to Mandate Full Crypto Transaction Reporting from 2026

As reported by CoinEdition, the UK will require domestic crypto platforms to report detailed user transaction data starting in 2026 under the expanded Cryptoasset Reporting Framework (CARF). The new rules will grant HMRC automatic access to both domestic and foreign crypto data for the first time, aiming to enhance tax transparency ahead of the 2027 global data exchange cycle. The framework will also apply to domestic transactions, requiring service providers to verify user identities and submit annual reports. Alongside this, the UK introduced a 'no gain, no loss' tax plan, delaying DeFi capital gains until token disposal. Industry figures, including Stani Kulechov, have criticized FCA policies for creating compliance frictions and limiting stablecoin usability.
