Global Crypto Tax Transparency Tightens as CARF Data Collection Starts in 2026

On 2 January 2026, dozens of countries began gathering detailed crypto transaction records ahead of the Crypto-Asset Reporting Framework's planned data exchanges in 2027. Platforms in 48 jurisdictions must now log wallet activity, trades, and transfers under new tax transparency rules, with the UK enforcing particularly strict reporting duties. A further group of countries is expected to join from 2028, signaling a shift toward cross-border visibility of crypto holdings and gains.
