According to TechFlow, dozens of major countries issued a joint statement that they agreed to a set of cryptocurrency tax rules, the Crypto Asset Reporting Framework (CARF), and planned to incorporate it into domestic laws and activate exchange agreements by 2027.

These countries hope to improve tax compliance and combat tax evasion through CARF. CARF is expected to start operating in 2027 and will be used by these countries to combat tax evasion using digital assets.
