Argentina commits to global crypto tax-sharing framework, joins 77 countries by 2029

Argentina will begin automatically sharing crypto transaction data with tax authorities in dozens of countries by September 2029, the OECD announced September 14, making it the 77th jurisdiction to commit to the organization’s Crypto-Asset Reporting Framework.

The framework is designed to improve authorities’ access to transaction information rather than introduce a new global cryptocurrency tax. The Global Forum said Argentina’s implementation will be monitored as the country works toward its 2029 exchange deadline.

Argentina crypto tax reporting expands global transparency

The OECD’s CARF is intended to create a standardized system through which participating jurisdictions collect and automatically exchange information about relevant crypto-asset transactions.

Unlike a policy that establishes a universal cryptocurrency tax rate, Argentina crypto tax reporting is primarily concerned with information sharing. National governments remain responsible for determining their own tax rules and obligations.

Under the framework, reporting crypto-asset service providers can be required to collect information about users and their transactions and provide that information to tax authorities. Those authorities can then exchange relevant information with the jurisdiction where a taxpayer is resident.

The OECD describes CARF as a response to the rapid growth of crypto markets and the cross-border nature of digital assets. Its framework includes domestic reporting requirements, international agreements for exchanging information and standardized electronic formats for transmitting the data.

Gaël Perraud, chair of the Global Forum, said Argentina’s decision represents a broader move toward international adoption of the framework.

The development means Argentina crypto tax reporting is moving from a primarily domestic issue toward a system with greater international coordination.

What CARF means for crypto investors

The practical importance of Argentina crypto tax reporting lies in the increased visibility of cross-border digital-asset activity.

CARF can cover information associated with crypto-asset users and relevant transactions processed by reporting service providers.

The OECD’s published framework includes requirements concerning taxpayer identification details as well as transaction information involving crypto assets.

The reporting framework operates through reporting crypto-asset service providers and participating jurisdictions, while implementation depends on domestic legislation and the relevant international exchange arrangements.

For Argentine residents using foreign crypto platforms, however, the broader direction is clear: international tax authorities are developing mechanisms that make cross-border crypto activity more visible.

The OECD said the framework was developed partly because crypto assets can provide opportunities for taxpayers to conceal income or wealth, particularly when assets are held or transactions occur abroad.

Perraud also said the initiative would strengthen the ability of Argentine tax authorities to obtain information concerning overseas crypto activity.

Argentina crypto tax reporting therefore represents an important compliance development rather than an announcement of a new cryptocurrency tax rate.

Argentina joins 77-jurisdiction CARF movement

Argentina’s commitment also increases the number of jurisdictions that have announced plans to implement CARF to 77.

The participating jurisdictions have committed to begin exchanges under the framework in different years, with implementation dates extending through 2027, 2028 and 2029. Argentina has selected September 2029 as its target for beginning automatic exchanges.

The Global Forum said it will monitor Argentina’s progress, while its secretariat will provide support during implementation.

For the crypto industry, the growing number of participating jurisdictions could gradually reduce the differences between domestic and international approaches to crypto tax information.

Service providers operating in jurisdictions implementing CARF may need systems capable of collecting appropriate tax-residency and transaction information.

The OECD has already published technical specifications and XML formats designed to support the transmission of CARF information between tax authorities.

What investors should watch before 2029

The 2029 deadline does not mean that investors should assume Argentina’s entire crypto tax regime will remain unchanged until then. CARF concerns information exchange, while Argentina’s domestic authorities retain responsibility for national tax rules.

Consequently, Argentina crypto tax reporting should be viewed as one part of a wider international shift toward greater transparency in digital assets.

Investors should pay particular attention to future Argentine legislation, regulatory guidance and reporting requirements that determine how CARF is implemented domestically. They should also maintain accurate records of crypto purchases, sales, transfers and other taxable activities where required under applicable law.

The OECD’s framework is already supported by technical infrastructure, including standardized reporting formats and guidance for tax administrations.

As more jurisdictions implement CARF, investors and crypto businesses operating across borders will face a regulatory environment in which tax residency, transaction records and reporting obligations become increasingly important.

Argentina crypto tax reporting is consequently set to become a key compliance consideration ahead of the country’s planned September 2029 start date.
