Argentina will begin automatically exchanging crypto-asset transaction data with foreign tax authorities by September 2029 under the Crypto-Asset Reporting Framework (CARF) from the Organization for Economic Co-operation and Development (OECD).

The OECD Global Forum on Transparency and Exchange of Information for Tax Purposes announced the commitment on September 14. Argentina becomes the 77th jurisdiction to formally join CARF, a system developed with G20 support to extend automatic tax information sharing to digital assets.

Under the framework, virtual asset service providers must collect and report user identity details such as names, addresses, tax residences, and taxpayer identification numbers. They will also report transaction data covering purchases and sales of crypto assets for fiat currency, crypto-to-crypto trades, payments in digital assets, and transfers to external wallets.

The data will flow to tax authorities in participating countries where the user is a tax resident. Argentina’s tax agency, known as ARCA, will gain access to information on its residents’ overseas crypto activity while sharing domestic data with other nations.

The commitment does not create new taxes or reporting obligations for users at this stage. Argentina must still incorporate CARF into domestic law, establish reporting systems for local providers, and finalize international agreements before exchanges begin. Most other participating jurisdictions plan to start sharing in 2027 or 2028.

Argentina has already taken steps toward greater domestic oversight of crypto. Earlier resolutions require platforms to submit monthly reports on user balances and transactions above certain thresholds. The new international commitment builds on those efforts.

The move aligns Argentina with a growing global network aimed at reducing tax evasion through crypto. Officials from the Global Forum noted that the system will equip tax authorities with better tools to track cross-border activity.

Implementation will require updates to Argentine regulations by 2028 at the latest. The OECD will monitor progress and offer support during the transition period.
