Argentina has signed on to the OECD’s Crypto-Asset Reporting Framework, or CARF, and committed to begin automatic exchanges of crypto-asset information with other participating countries by September 2029.
The framework creates a common reporting standard for crypto transactions across borders. For Argentine users, the practical impact is expected to center on compliance and disclosure rather than any immediate new tax, especially for tax residents who use exchanges based in other CARF countries.
What Argentina agreed to
By joining CARF, Argentina agreed to take part in an international system for reporting crypto-asset activity. The OECD said Argentina’s sign-up raises the number of CARF participants to 77.
Under the framework, countries collect specified data through qualifying crypto service providers and then share that information automatically with other jurisdictions. Argentina’s commitment means it plans to be part of that exchange network by September 2029.
How reporting could reach Argentine tax authorities
The change is particularly relevant for Argentinians using exchanges abroad. If an Argentine tax resident uses a qualifying exchange in a country that has implemented CARF, that platform could identify the customer as an Argentine tax resident under its local due diligence rules.
Once identified, the user’s transaction details could be reported under that country’s CARF regime and then shared through the international system, potentially reaching Argentina’s tax authorities. In that sense, the framework can expand the flow of information even when the trading platform itself is outside Argentina.
Transfers and self-hosted wallets are also within scope
CARF is not limited to trades held entirely on regulated platforms. The framework also covers transfers, including those sent to external or self-hosted wallets, when the transfer is processed by a crypto service provider.
At the same time, self-custody wallets are not treated as separate reportable accounts under the framework. Reporting remains tied to the user who initiates the transaction through the service provider, rather than to the wallet itself as an independent account holder.
What happens before 2029
Argentina still has several steps to complete before automatic sharing begins. According to the source article, the country must incorporate CARF into its own legal framework, build reporting and due diligence systems, and put the necessary international data-sharing agreements in place.
The OECD is expected to monitor progress toward the September 2029 deadline. In the meantime, exchanges may begin tightening compliance processes, including requests for additional customer information such as proof of tax residence.
What CARF does not change
The reported commitment does not by itself create a new crypto tax in Argentina. CARF is a reporting and information-sharing mechanism, not a rule that decides whether a transaction is taxable or how much tax is owed.
Those questions remain governed by Argentina’s domestic tax laws. The next confirmed milestone is the country’s work to implement the framework ahead of the 2029 start date for automatic cross-border sharing.
