Chainalysis estimates $457B in taxable crypto activity, says CARF misses most

Blockchain analytics firm Chainalysis estimates that crypto activity potentially subject to taxation totals $457 billion. However, only 14% of the onchain activity it identified falls within the scope of the OECD’s Crypto-Asset Reporting Framework, or CARF. The finding indicates that most of the taxable activity tracked by Chainalysis is not covered by the international crypto tax-reporting framework. CARF was developed by the OECD to support the exchange of crypto-asset tax information between jurisdictions. Chainalysis’ assessment highlights a significant gap between the scale of taxable crypto activity and the transactions captured by the framework. The firm’s estimate was reported on August 26, 2026, according to Cointelegraph. The data concerns onchain activity and the share identified as covered by CARF; it does not provide a breakdown by asset, jurisdiction, or transaction type.
