France plans to share crypto tax data with 48 nations
France wants broader access to crypto tax records. A bill introduced on July 17 would let the country share user data with 48 other nations. Why does this matter? Because investors who trade across borders may soon face a much clearer record of where their money goes. The gap is closing.
Jean-Noël Barrot, France’s Minister for Europe and Foreign Affairs, introduced text 921 in the Senate. The bill would incorporate the OECD’s Crypto-Asset Reporting Framework, or CARF, into French law. France could then exchange records with the 48 countries that signed the agreement in Paraguay in November 2024. The scope is precise: individual transactions, names, addresses, tax identification numbers, country of residence and the total amount traded during each reporting period. My take: that is an unusually detailed picture of a person’s finances. EU governments are preparing a similar exchange system under the DAC-8 directive, which takes effect on September 30, 2027.
The proposal comes amid a grim increase in crypto-related crime in France. According to the source, the country accounts for most reported “wrench attacks,” the blunt name for robberies in which criminals use violence to force victims to hand over cryptocurrency. Chainalysis counted 30 publicly known incidents through 2026, though the true number could be higher. Some involved kidnappings or home invasions. This is not abstract. Reports have linked the increase to a French tax official in the Paris area who allegedly sold information about wealthy crypto holders. I’ll be honest: that allegation casts a nasty shadow over plans to share even more data.
Most arguments about the bill focus on tax compliance. That is only half right. Data security matters just as much when names, addresses and transaction records can identify wealthy holders. France dropped an earlier proposal that would have required users to declare assets in self-custody wallets after deputies argued that officials had no realistic way to verify the declarations. Text 921 takes a different route. Institutions would collect the records and exchange them across borders.
The bill would create more work for exchanges and other reporting platforms. They may have to tighten identity checks and anti-money-laundering controls; their customers, meanwhile, would give up more privacy. Enforcement actions have moved markets before. In February 2023, Kraken agreed to pay $30 million after the US Securities and Exchange Commission went after its staking service, and staking-related tokens briefly dropped. But this is different. The French bill does not target a particular protocol or product, so the immediate market reaction may be muted.
Counter to the usual advice, moving assets into self-custody does not necessarily erase the trail. Data from centralized exchanges may still show when funds entered, where they went and who probably controlled them. Is that enough to identify every wallet owner? No. It does, however, reveal how governments plan to track crypto: pool their records and compare notes. I would not dismiss that distinction.
The bill could also change how money travels between crypto and traditional markets. Inflation and higher interest rates already influence investment decisions. Governments, for their part, do not want digital assets to become an easy channel for tax evasion or capital flight. Once 48 countries share information, cross-border transfers become much easier for tax authorities to follow. Institutions with strict confidentiality concerns may retreat, although nobody knows how many would do so. That uncertainty matters.
Bitcoin (BTC) is often pitched as insurance against trouble in the traditional financial system. Shared reporting does not kill that case, but it does make discreet transfers more difficult. Yes, that sounds contradictory: an asset can remain independent of banks while becoming easier for governments to trace. Both can be true. Something similar happened in early 2022, when concern about the EU’s MiCA rules led some funds to leave European exchanges. Text 921 has a narrower scope than MiCA, but traders may still reconsider where they store assets. They may also rethink which jurisdictions they use. My read: custody choices could shift before the broader investment case does.
What this means
Crypto tax enforcement is going international. Anyone who uses a centralized exchange should expect transaction records to reach tax authorities beyond the country where the account is based. Governments see crypto as a source of unpaid tax, and CARF gives 48 participating nations a way to compare information. Some investors might declare more of their activity. Others may move to countries with looser rules. But with 48 governments taking part, there are fewer practical places to go. The shadows are shrinking.
Investors should pay attention to how France puts the framework into practice, particularly which businesses must report and what information they must provide. The bill does not target a specific token. That sounds reassuring. It may not be. Privacy coins and decentralized finance (DeFi) services could still move if traders become nervous about traceability. Trading volumes on exchanges in France and the other participating countries may provide an early signal.
September 30, 2027 is another date to note because DAC-8 takes effect across the EU then. OECD announcements on CARF are worth watching too. Why watch technical implementation details? Because wider rules could raise reporting costs before they produce any obvious market reaction. They could also unsettle the market. In my view, the reporting perimeter will tell investors more than the bill’s broad language.
FAQ: France’s crypto tax data sharing bill
Q: What would France’s new crypto bill do?
A: Text 921 would incorporate the OECD’s Crypto-Asset Reporting Framework into French law. It would also permit the automatic exchange of crypto tax information with other participating countries.
Q: Which international framework does the bill adopt?
A: The bill adopts the Crypto-Asset Reporting Framework, or CARF, created by the Organization for Economic Co-operation and Development.
Q: How many nations would receive data from France?
A: France would exchange crypto tax records with the 48 nations that signed the CARF agreement in Paraguay in November 2024.
Q: What information would be exchanged?
A: The records would contain individual transactions and users’ names and addresses. They would also include tax identification numbers, countries of residence and the total amount transacted during each reporting period.
Q: How is the bill connected to DAC-8?
A: Both measures cover the exchange of crypto tax records. EU states are setting up their own system under DAC-8, which takes effect on September 30, 2027.
Q: What is a “wrench attack”?
A: It is a robbery in which criminals use or threaten physical violence to steal cryptocurrency. Reported attacks in France have included kidnappings and home invasions.
Q: What reportedly caused the rise in attacks on wealthy French crypto holders?
A: The source connects some of the increase to a tax official near Paris who allegedly sold personal information about wealthy French cryptocurrency owners.
Q: Did France previously consider reporting rules for self-custody wallets?
A: Yes. France considered making users report assets held in self-custody wallets. It dropped the proposal after deputies said officials could not verify the declarations.
Q: How might exchanges and platforms be affected?
A: They may need to gather more information about customers and tighten identity checks. They may also have to file records under the international data-sharing system.
Q: Does the bill create a precedent for other governments?
A: It gives other countries a model for tracking crypto holdings through shared tax records instead of depending solely on domestic enforcement.
Q: Could greater visibility affect institutional investors?
A: It could. Institutions that put a high value on confidentiality may cut their exposure or trade elsewhere. Still, it is too early to judge how large that response might be.
Q: Why does September 30, 2027 matter?
A: DAC-8 takes effect on that date, expanding crypto tax information exchanges across EU member states.
Q: What details should investors watch?
A: Investors should watch which companies have to report and which customer records France exchanges. They should also track whether the OECD expands CARF or alters its requirements.
Q: Could privacy coins or DeFi protocols be affected?
A: The bill does not name any token. Privacy coins and DeFi services could still move if traders think the reporting system will make their activity easier to follow.
