Chainalysis estimates $457 billion in global onchain taxable crypto activity in 2025, with CARF covering only 14% of transactions.

Chainalysis estimates that at least $457 billion in onchain taxable crypto activity occurred globally in 2025, according to analysis reported by The Block. The Common Reporting Standard (CARF), an international framework for exchanging tax information, covers only 14% of such transactions, highlighting a substantial gap in cross-border crypto tax reporting coverage.
The discrepancy between total taxable activity and CARF-covered volume underscores the ongoing fragmentation in global crypto tax compliance infrastructure. While CARF represents a coordinated effort among participating jurisdictions to share financial account information, the framework's limited reach leaves the majority of identifiable onchain transactions outside formal international tax reporting mechanisms.
The implications for tax authorities and compliance remains unclear—specifically whether the uncovered 86% reflects activity in non-CARF jurisdictions, transactions that fall outside reporting thresholds, or a combination of structural and regulatory gaps. Further detail on the composition of this activity and efforts to expand reporting coverage was not provided.
