The European Union will begin enforcing the Crypto-Asset Reporting Framework (CARF) on January 1, 2026, as part of the DAC8 directive. This initiative mandates that crypto exchanges, brokers, and custodial services report user transactions to tax authorities. Developed by the OECD at the G20's behest, CARF extends the Common Reporting Standard (CRS) to include cryptocurrencies, requiring disclosures of crypto-to-fiat exchanges, crypto-to-crypto trades, and transfers. As of December 4, 75 jurisdictions have committed to adopting CARF, according to an OECD report. The framework applies to centralized exchanges, crypto brokers, custodial wallets, and certain DeFi operators with protocol control. While the EU will implement CARF in 2026, regions like Singapore and other Asia-Pacific countries plan to delay adoption until 2027. CARF works alongside the updated CRS 2.0, which covers financial accounts, including CBDCs and crypto access via derivatives or investment funds, ensuring no double reporting occurs.
