The blockchain analytics firm says OECD reporting rules cover only 14% of the activity identified in 2025.
Potentially taxable onchain crypto activity reached at least $457 billion globally in 2025, but international reporting rules may cover only a small share of it, according to Chainalysis data reported by Cointelegraph.
The United States accounted for an estimated $112.6 billion of the total. North America led regions with $134.6 billion, followed by the European Union with $125.1 billion.
The estimate includes realized gains, income from mining, staking and lending, and crypto-denominated payments across six blockchains. It excludes trading and other activity on centralized exchanges.
Chainalysis said transactions covered by the OECD’s Crypto-Asset Reporting Framework account for only 14% of the onchain taxable activity it identified. The remaining 86% includes decentralized-exchange activity, peer-to-peer transfers, onchain income and payments.
CARF began collecting data on Jan. 1, 2026, in 48 jurisdictions, including the United Kingdom and European Union. Covered crypto providers must collect customer and tax-residency information and report transactions to domestic tax authorities.
The framework’s focus on intermediaries leaves much of decentralized finance outside its reporting perimeter because some platforms have no centralized operator or custodial relationship.
