CARF (Crypto-Asset Reporting Framework)
A global OECD standard for the automatic exchange of tax information about crypto transactions between countries.
CARF (Crypto-Asset Reporting Framework) is a global standard developed by the OECD in 2023 for the automatic exchange of tax information about crypto transactions between different countries' tax administrations. It requires crypto-asset service providers to collect data on customer transactions and pass it to national tax authorities, who then exchange that data with the countries where the customers are tax residents.
Over 40 countries had committed to implementing CARF as of its introduction, with reporting generally expected to begin from 2027 onward — the exact timeline and local implementation details vary by country. The definition of a covered service provider under CARF is broader than any single country's exchange-licensing category and overlaps heavily with the VASP concept used in AML regulation.
