Chainalysis Reports $457 Billion in Potentially Taxable Crypto Activity for 2025

According to a recent report by Chainalysis, potentially taxable onchain crypto activity reached at least $457 billion globally in 2025. The United States alone accounted for approximately $112.6 billion of this total, making it the largest contributor.

North America led all regions with $134.6 billion, followed closely by the European Union at $125.1 billion. The estimate includes realized gains, income from mining, staking, lending, and crypto-denominated payments across six blockchains, excluding trading and other activities on centralized exchanges.

Chainalysis highlighted that transactions covered by the OECD’s Crypto-Asset Reporting Framework (CARF) only account for 14% of the identified onchain taxable activity. The remaining 86% consists of decentralized exchange activities, peer-to-peer transfers, onchain income, and payments, which largely evade current reporting requirements.

The CARF framework, which began collecting data on January 1, 2026, aims to enhance transparency by requiring covered crypto providers to report customer and tax-residency information to domestic tax authorities. However, its focus on intermediaries leaves much of decentralized finance outside its reporting scope, as many platforms operate without a centralized operator or custodial relationship.
