Jurisdictions around the world are beginning to collect digital asset transaction data for tax purposes under the OECD’s Crypto-Asset Reporting Framework (CARF).

As of January 2026, 48 jurisdictions have implemented CARF-aligned reporting requirements that compel crypto service providers, including centralized exchanges, some decentralized platforms, brokers, and crypto ATMs, to gather customer transaction data. These include all EU member states, Brazil, Chile, Israel, Japan, New Zealand, South Africa, and the United Kingdom. 

In the UK, for example, exchanges and platforms must now report user transactions and tax residency information to HM Revenue & Customs. 

CARF is designed to increase tax transparency, combat money laundering, and help authorities enforce digital asset tax compliance. 

While the first international exchanges of information in these jurisdictions are not due until 2027, January 1, 2026, was the effective date for them to implement legislative frameworks as well as reporting procedures. 

Similarly, the 27 jurisdictions undertaking the first exchanges of digital asset data for tax purposes in 2028 are expected to have the legislative frameworks and reporting procedures for doing so in place by January 1, 2028. These include Australia, Canada, Hong Kong, Malaysia, Mexico, Nigeria, the Philippines, Singapore, and the UAE. The United States is committed to implementing CARF exchanges in 2029.

The OECD said in a November 2025 update: 

An increasing number of jurisdictions implementing the CARF for first exchanges in 2027 either already have their necessary legislation in force to require Reporting Crypto-Asset Service Providers to collect CARF-related information from their customers and to report such information to the jurisdiction’s tax authority or are in the final stages of bringing it into force. The remainder are expected to do so soon.

CARF’s steps are similar to the OECD’s existing Common Reporting Standard for traditional financial accounts, but tailored to digital assets and services.
