US Considers Joining Global Crypto Tax Data Sharing Framework (CARF)

The White House is currently reviewing a proposal from the Internal Revenue Service (IRS), known as the “Broker Digital Transaction Reporting” proposal, which would align the US with the global Crypto-Asset Reporting Framework (CARF).

• Goal: Joining CARF would grant the IRS access to foreign crypto account data held by Americans, aiming to combat international tax evasion.
• Global Context: CARF was established by the Organization for Economic Cooperation and Development (OECD) in late 2022 to facilitate the sharing of cryptocurrency data among member nations.
• Timeline: 72 other countries have already committed to implementing CARF, with 50 aiming for a 2027 rollout and the remaining 23 (including the US) aiming for 2028.
• Impact on Taxpayers: The proposal would require Americans to be much more rigorous in reporting capital gains tax from foreign crypto platforms. The White House supports CARF implementation as a way to discourage moving digital assets to offshore exchanges and maintain a fair playing field for US crypto platforms.

Stricter Local US Tax Rules Coming in 2026

The move toward international data sharing comes alongside tougher domestic crypto tax regulations:

• New Form: The US is set to roll out 1099-DA forms in January 2026, which will require US-based crypto exchanges to report more detailed transaction data, including inward and outward transfers.
• End of Anonymity: A crypto tax lawyer noted that the 1099-DA will significantly reduce crypto anonymity, giving the IRS better tools for scanning blockchain networks to identify and audit non-reporters in the future.
