Woofun AI reports that a massive reporting gap exists within global crypto taxation, as Chainalysis identifies $457 billion in potentially taxable onchain activity for 2025 that largely evades current international standards. This discrepancy is highlighted by Colby Mangels, a former OECD adviser, who notes that the existing framework fails to capture the majority of decentralized economic interactions.

The geographic distribution of this taxable volume reveals significant regional concentrations, with the United States accounting for an estimated $112.6 billion of the total. North America leads all regions with $134.6 billion, followed closely by the European Union at $125.1 billion. These figures encompass realized gains, mining, staking, lending income, and crypto-denominated payments across six major blockchains, while explicitly excluding activity conducted within centralized exchanges.

Structurally, the OECD's Crypto-Asset Reporting Framework (CARF) covers only 14% of the onchain taxable activity identified by Chainalysis. The remaining 86% remains invisible to tax authorities, comprising transactions on decentralized exchanges, peer-to-peer transfers, onchain income streams, and payments. This exclusion means that realized gains, mining, staking, lending, and crypto-denominated payments outside centralized venues are not currently reported under the framework.

Per Woofun AI, the mechanics of CARF, developed by the OECD in 2022, rely on covered crypto service providers to report customer transaction data and tax residency information to domestic tax authorities. Data collection began on Jan. 1, 2026, in 48 jurisdictions, including the United Kingdom and the European Union. This intermediary-focused model requires platforms to collect additional customer details, which are then shared across borders, but it inherently excludes non-custodial interactions.

The regulatory perimeter remains fixed on intermediaries that facilitate transactions as a business, leaving much of decentralized finance outside the reporting scope due to the absence of centralized operators. As noted by Colby Mangels in January, regulators are now monitoring anti-money laundering regulation developments to determine when DeFi platforms should be treated as regulated crypto service providers.

This shift suggests future reporting obligations may expand beyond traditional custodial relationships.
