The OECD's Crypto-Asset Reporting Framework (CARF) is being adopted by numerous countries to standardize global crypto tax reporting. According to NS3.AI, this initiative aims to enhance oversight by integrating fiat transaction data, on-chain analytics, and exchange ledger disclosures. Over 70 nations have pledged to implement CARF, with cross-border data exchanges anticipated to commence in 2027, signaling more stringent crypto tax regulations in the future.
