Chainalysis has offered a new perspective on crypto taxation, projecting that taxable crypto activity will total $457 billion globally by 2025. The United States accounts for $112.6 billion of that amount. Yet the OECD's transparency rules will bring only a small portion of this activity into view, highlighting the gap between on-chain activity and what tax authorities can see through intermediary reporting. The projection was made public today in a Chainalysis report.

The $457 Billion Baseline

The estimate combines realized profits, income from mining, staking, lending, and gambling, and crypto payments across six blockchains: Bitcoin, Ethereum, Solana, Tron, BNB Chain, and Base.

Internal trading between users of exchange platforms is not counted, which makes the figure a lower-bound estimate. By region, North America leads with $134.6 billion, while Europe follows at $125.1 billion. Germany, China, and the UK rank just behind the United States in the country-level ranking.

CARF Is Limited Because It Tracks Only 14%

The Crypto-Asset Reporting Framework (CARF), created by the OECD, has been active in 48 jurisdictions since January 1, 2026. Much of the market, however, operates with no intermediary in place to collect residency information or keep track of how much someone has paid for a token.

The taxman is staring at a $457B crypto pile. Chainalysis says that's the lower bound for potentially taxable on-chain activity in 2025. CARF only covers about 14% of it though, so DeFi and P2P are still mostly in the dark. US led the list at $112B. pic.twitter.com/KFFpzr02Dx

According to Chainalysis, only 14% of taxable on-chain transactions are covered by the system, while the remaining 86% occur on decentralized platforms where no third party is involved — spanning decentralized exchanges, peer-to-peer purchases, self-custody wallets, and stablecoin payments.

Beyond Intermediary Reporting

From the perspective of exchanges, custodians, and regulators, the discrepancy shows that reliance on intermediary reporting is not always viable, especially when a large share of activity moves through rails that do not naturally produce residency or cost-basis records. Investors carry the burden of self-reporting gains from DeFi and peer-to-peer activity, while institutions must perform analysis to identify taxable events.

The IRS Form 1099-DA and South Korea's soon-to-arrive regime will add to CARF, but governments will still have to combine the reporting received from their providers with an understanding of the underlying activity to obtain an accurate picture.
