Potentially taxable onchain cryptocurrency activity reached at least $457 billion worldwide in 2025, according to a recent report published by Chainalysis, a blockchain analytics firm. This figure reflects crypto transactions generating realized gains, onchain payments, and income sources such as mining, staking, and lending, based on data from six major blockchains. Activity confined within centralized exchanges was not included in the calculations.
Regional breakdown of taxable activity
North America led all global regions, with an estimated $134.6 billion in onchain crypto gains and income. The United States contributed $112.6 billion of that North American total. The European Union followed with $125.1 billion in potentially taxable onchain transactions during the same period.
The report emphasized that these estimates focus on external, onchain transactions and do not account for trades and movements happening solely within centralized exchanges. By excluding these internal exchange activities, the analysis aimed to capture the portion of crypto activity most relevant to tax authorities and blockchain transparency efforts.
| Region | Taxable Onchain Crypto Activity ($B) |
|---|---|
| North America | 134.6 |
| United States | 112.6 |
| European Union | 125.1 |
| Global total | 457.0 |
Gaps in reporting and OECD’s CARF
Chainalysis found that only 14% of the identified potentially taxable crypto transactions are covered by the Organisation for Economic Co-operation and Development’s Crypto-Asset Reporting Framework (CARF). The remaining 86% consists primarily of transactions conducted through decentralized exchanges, peer-to-peer transfers, and onchain income payments, sectors typically less visible to regulators.

AAPLCARF, introduced by the OECD in 2022, mandates that crypto service providers in participating jurisdictions report customer transaction and tax residency data directly to their respective tax authorities. The system is intended to improve tax compliance by increasing transparency in crypto markets.
The first phase of CARF data collection began on January 1, 2026, across 48 jurisdictions, including the United Kingdom and all members of the European Union. During this rollout, covered platforms are required to gather more detailed customer information and share it with domestic tax agencies, facilitating international information exchange.
Chainalysis noted that the limited scope of CARF arises from its design: it applies mainly to intermediaries, such as centralized crypto platforms, that act as official custodians or facilitators of transactions.
Colby Mangels, a former adviser to the OECD and contributor to the CARF framework, explained that the framework focuses on business intermediaries rather than decentralized protocols, leaving many DeFi activities outside its perimeter.
Colby Mangels emphasized that CARF was constructed to regulate intermediaries facilitating client crypto transactions as a business, and that this approach explains the substantial reporting gaps for decentralized activities.
Because decentralized protocols typically operate without a central administrator or custody relationship, much of decentralized finance currently falls outside tax reporting obligations under CARF.
Mangels stated that tax authorities are increasingly monitoring regulatory changes in the anti-money laundering space and examining whether operators or developers of decentralized platforms should be subject to similar oversight as centralized crypto providers.
Ongoing regulatory developments could eventually extend the reach of frameworks like CARF to encompass a wider range of decentralized protocols, as authorities aim to improve enforcement and close loopholes in crypto tax collection.
