France moved closer to sharing crypto tax data with foreign authorities on October 27, 2026, when the French Senate approved Bill No. 921 . The measure would authorize participation in the OECD’s international reporting framework, but it still needs National Assembly approval. It creates no new tax: the change concerns how authorities exchange information they collect.
Key takeaways
Senate approval is not the final legislative step.
CARF reporting includes user identification, transaction totals and certain self-custody transfers.
The initial CARF exchanges are planned for 2027 across 46 jurisdictions.
France’s crypto tax data bill awaits National Assembly approval
The bill would establish the legal basis for France to implement the OECD’s Crypto-Asset Reporting Framework (CARF) and automatically exchange cryptocurrency tax information with participating jurisdictions.
The Senate’s first-reading approval covers agreements signed in Asunción, Paraguay. France signed the multilateral agreement on November 26, 2024 . Passage through the National Assembly remains necessary before approval can be finalized.
What platforms would report under CARF
Reporting crypto-asset service providers would submit users’ identities, tax residence and tax identification numbers, alongside detailed transaction information. The framework covers transaction counts, quantities and aggregate values, broken down by asset and transaction type.
That reporting includes conversions between crypto and fiat currencies, crypto-to-crypto swaps and transfers. It also extends to certain transfers involving self-custody wallets , where users hold their own private keys.
Having these transfers reported does not grant tax agencies any direct entry into the wallets involved, since the requirement only involves disclosing information about qualifying transfers rather than accessing the actual assets stored in a wallet.
Linking domestic reporting with cross-border tax cooperation
CARF aims to improve cross-border tax compliance by connecting national reporting systems through automatic information exchanges. Tax administrations would exchange the reported information annually , with implementation beginning in phases from 2027.
France’s crypto tax data arrangements would therefore extend beyond domestic collection into cooperation with foreign tax authorities. The framework seeks to make taxable activity across borders harder to conceal by bringing crypto-asset information into established international tax cooperation.
CARF and DAC8 exchange dates
Set to launch in 2027 , the initial round of CARF exchanges is anticipated to involve 46 jurisdictions from the outset. That group includes France, Germany, the UK, Japan and Canada.
Participation is set to broaden: 77 jurisdictions have committed to implementing the framework in 2027, 2028 or 2029.
France began collecting domestic crypto data under the EU’s DAC8 rules on January 1, 2026. The first DAC8 exchanges covering information from 2026 are due by September 30, 2027 .
