French lawmakers have approved an amendment requiring holders of self-custodied crypto assets worth €100,000 ($112,000) or more to report their holdings or face fines of up to €10,000.
The amendment, numbered I-CF821, was adopted by the National Assembly’s Finance Committee on Friday. It targets crypto assets not held with licensed crypto-asset service providers, including those stored in personal wallets. Holders would need to declare the value of such assets as of December 31. The proposal was introduced by Charles de Courson, Jean-Pierre Bataille and Michel Castellani from the LIOT parliamentary group.
They argued the measure is needed to combat tax evasion, citing a parliamentary inquiry that found crypto capital gains reached €3.5 billion in 2021 while only €400 million in holdings were declared to tax authorities.
The wallet disclosure rule was one of five crypto-related amendments passed by the committee. Others include an exit tax on crypto holdings exceeding €800,000 when taxpayers leave the country and the end of tax deferrals on conversions into fiat-backed stablecoins. However, the committee later rejected the revenue section of the broader 2027 budget bill. Lawmakers are due to begin debating the government’s original draft in the National Assembly on Tuesday, meaning the crypto amendments will need to be reintroduced and approved during the parliamentary process before they can become law.
The push for stricter reporting comes as France continues to record a high number of crypto-related violent crimes. Between January 1 and mid-August 2026, authorities registered 90 cases of kidnapping, extortion, threats and violent thefts linked to cryptocurrency. The Interior Ministry also reported 223 arrests and 126 detentions from January to July — roughly one incident every two and a half days. Official comparative figures for 2025 are unavailable because systematic tracking only began this year.
Independent trackers paint a similar picture. Chainalysis recorded at least 30 known physical crypto attacks in France by mid-2026, while Gart.io logged 73, placing the country ahead of the United States (66) and the United Kingdom (27). Bitcoin security expert Jameson Lopp has documented 365 physical attacks across 60 countries from 2014 to 2026, with France ranking first on the list.
The combination of new disclosure requirements for self-custodied wallets and elevated levels of physical violence creates a particularly challenging environment for crypto holders in France.
