France Moves Closer to Global Crypto Tax Data-Sharing Agreement

France's Senate approved a bill at first reading on Tuesday to ratify the Organisation for Economic Co-operation and Development's (OECD) international tax-transparency framework for crypto-assets. The decision brings France closer to exchanging information on crypto transactions automatically with dozens of jurisdictions as governments strengthen oversight of digital-asset activities.

The legislation covers the multilateral agreement implementing the Crypto-Asset Reporting Framework (CARF), signed in Asunción, Paraguay, on November 26, 2024. It also incorporates an addendum expanding the Common Reporting Standard (CRS), the OECD's existing mechanism for the automatic exchange of financial-account information, according to the text adopted by the Senate.

The bill is proceeding under an accelerated legislative process. This allows it to advance to a joint parliamentary committee after receiving one reading in each chamber, rather than undergoing the two readings normally required. Its next stage is consideration by France's National Assembly.

Crypto Service Providers Face New Reporting Obligations

Under CARF, crypto-asset service providers will be required to carry out additional due diligence and collect information about their customers and transactions. France's tax administration will use the reported data to prepare and exchange information with participating jurisdictions, according to the government's impact assessment accompanying the legislation.

The framework covers crypto-assets falling within the scope of the European Union's Markets in Crypto-Assets (MiCA) regulation. Meanwhile, the CRS addendum broadens the existing reporting standard to include certain electronic-money products, selected central bank digital currencies (CBDCs), and indirect exposure to crypto-assets through derivatives and investment funds.

These provisions extend the scope of international tax reporting beyond conventional financial accounts, bringing additional digital financial products and investment structures within the information-sharing system.

Dozens of Jurisdictions Have Signed the Global Crypto Tax Agreement

The government's impact assessment reported that 49 jurisdictions had signed CARF when the agreement opened for signature in November 2024. That number had risen to 56 by March 2026. In addition, 72 jurisdictions had signed the addendum to the Common Reporting Standard.

France plans to begin exchanging information collected during 2026 in 2027. However, the assessment acknowledged that some participating jurisdictions could postpone implementation until 2028 because of technical or operational challenges.

The timetable therefore depends not only on France's domestic legislative process but also on the readiness of its international partners to collect, process, and exchange the required information.

CARF Implementation Aligns With the EU's DAC8 Rules

France's ratification of the agreement is connected to the European Union's DAC8 directive, which recognizes CARF as an equivalent reporting standard, according to the impact assessment.

This alignment is intended to avoid duplicate reporting requirements for certain foreign providers. Crypto-asset service providers outside the EU that already report under CARF in their home jurisdictions will not be required to submit the same information directly to French tax authorities.

France incorporated DAC8's provisions into its national legislation through the 2025 Finance Act, establishing a domestic legal basis for the EU's expanded crypto-tax reporting requirements.

Millions of French Residents Could Fall Within the Reporting System

The government's assessment estimated that the global crypto-asset market was worth approximately $1.1 trillion at the end of 2023. It also estimated that between 1.5 million and 5 million people in France held or used crypto-assets, equivalent to around 3% to 9% of the country's adult population.

These estimates illustrate the potential reach of the new reporting framework as authorities expand their ability to obtain information about digital-asset holdings and transactions.

The precise impact on individual users will depend on the applicable reporting rules, the information collected by service providers, and how participating tax authorities implement the framework.

International Crypto Tax Reporting Is Becoming More Coordinated

France's move to ratify CARF reflects a broader effort to bring crypto-assets within established systems of international tax transparency. As more jurisdictions adopt common reporting standards, cross-border information exchange could make it more difficult for taxpayers to rely on differences between national reporting systems to keep crypto-related activity outside tax authorities' view.

The practical effect, however, will depend on how consistently countries implement the framework and how effectively they coordinate data collection and exchange. France's planned 2027 rollout represents an important step, but potential delays in other jurisdictions could create uneven implementation. For crypto businesses, this shift points to the growing importance of reliable customer records, transaction monitoring, and compliance procedures. For individual users, the key distinction is that automatic information sharing increases tax authorities' visibility into crypto activity; it does not, by itself, establish a new tax or mean that every reported transaction is taxable.
