France to Join OECD Crypto-Asset Reporting Framework in 2027, Aligning with EU DAC8
In a decisive step that will bring French crypto transactions into the same global reporting framework as traditional finance, Paris is set to roll out the OECD’s Crypto‑Asset Reporting Framework (CARF) next year. The move, announced in the 2026 finance bill’s annual report, does not introduce new domestic law but confirms France’s participation in the international data‑exchange regime.
By 30 September 2025, 52 jurisdictions—including France—had signed the multilateral CARF agreement. The first wave of data exchanges will cover the 2026 reporting period and will be transmitted in 2027. Under CARF, crypto‑asset service providers (CASPs) must collect identifying details—names, addresses, tax identification numbers and jurisdiction of residence—from users, and then report aggregated transaction data broken down by crypto asset and transaction type to their home tax authority.
France’s implementation of CARF is anchored in the European Union’s Directive on Administrative Co‑operation in the field of Taxation (DAC 8). DAC 8 entered force on 1 January 2026 and mirrors the OECD standard. It obliges CASPs to gather information on any reportable transaction involving EU residents. Providers must submit their first reporting year’s data in 2027, and the EU tax authorities are required to exchange this information by 30 September 2027. That deadline signals the first exchange under DAC 8, not the commencement of the directive’s application.
The reporting rules do not create a universal register of every self‑custodied wallet or transaction. Instead, data is collected only when a covered CASP facilitates a reportable exchange or transfer. International agreements that underpin CARF and DAC 8 include strict confidentiality and data‑protection clauses that govern how exchanged information can be used, stored and shared.
Collecting detailed financial and identifying data will raise the stakes for robust access controls and cybersecurity across participating tax administrations. Automatic reporting is expected to make cross‑border crypto activity more transparent to tax authorities, thereby curbing opportunities for taxpayers to hide income on foreign platforms. The resulting international datasets—encompassing both financial and identity information—will place heightened emphasis on security, proportionality and strict limits on data access to maintain public trust.
France’s participation follows the OECD’s broader initiative to standardise the automatic exchange of crypto‑asset transaction data. CARF was formally launched in 2025 and initially covered 48 countries and regions. The framework builds on the Common Reporting Standard and seeks to mitigate emerging tax‑evasion risks linked to digital assets.
In sum, France will begin exchanging crypto‑asset transaction data with partner tax authorities in 2027 under CARF, in line with the EU’s DAC 8 implementation. The first exchanges will cover the 2026 reporting period, and CASPs must submit data for the first reporting year during 2027. The initiative will enhance cross‑border visibility of crypto activity, reinforce data protection and cybersecurity measures, and support the broader goal of tax transparency in the digital‑asset sector.
