[48 Jurisdictions to Implement the CARF Framework by 2026] According to the Crypto-Asset Reporting Framework (CARF) released by the OECD, 48 jurisdictions, including the UK and the EU, will officially begin collecting standardized data starting January 1, 2026. The framework requires service providers to collect detailed customer information, verify tax residency, and report user balances and transactions annually to local tax authorities. The data will be shared across borders through information exchange agreements. Lucy Frew, a partner at international law firm Walkers, stated that CARF will transform compliance models for digital asset businesses, requiring exchanges to redesign KYC and anti-money laundering processes and upgrade reporting systems. Asher Tan, CEO of UK-based exchange CoinJar, noted that users will need to provide additional tax residency information. Tax professionals recommend that users address historical tax issues during the voluntary disclosure period.
