France Backs Annual Disclosure Rule for Self-Custody Crypto Holdings Above 100,000 Euros

Published October 12, 2026, 11:40 PKT. Based on October 12, 2026 reporting by Cointelegraph, Crypto Breaking and Grafa, with legislative context from French tech publication Clubic and prior MABOnChain coverage of the 2027 budget fight.

France's National Assembly Finance Committee adopted an amendment on Friday that would require holders of self-custodied crypto assets worth 100,000 euros or more, about $112,000, to declare those holdings to tax authorities each year, Cointelegraph reported. The rule covers crypto not held through a crypto-asset service provider, meaning coins sitting in personal wallets rather than on exchanges, and would add the requirement as a new provision of France's general tax code. Under the proposal, holders would report holdings based on their value as of December 31, and failure to declare could bring fines of up to 10,000 euros.

The amendment, numbered I-CF821, was introduced by Charles de Courson, Jean-Pierre Bataille and Michel Castellani, three members of France's Liberties, Independents, Overseas and Territories (LIOT) parliamentary group, according to the report. The disclosure rule was one of five crypto-related amendments the committee adopted during its review of the 2027 budget bill.

The 3.5 billion euro gap behind the rule

The sponsors said the measure is aimed at combating tax evasion, citing a parliamentary inquiry into the taxation of wealthy individuals that found crypto capital gains in France reached 3.5 billion euros in 2021, while only 400 million euros in crypto holdings were declared to tax authorities that year, Cointelegraph reported. Holdings parked with regulated intermediaries are already visible to the state through those providers; coins held in private wallets are not, and the amendment targets exactly that blind spot.

The 100,000 euro line leaves ordinary holders untouched while catching serious balances, as one analysis noted. It is a disclosure rule, not a new tax: holders would report what they control, not hand over a cut at the filing deadline.

France's crypto-tax pileup

The wallet disclosure measure lands alongside two other crypto amendments the committee advanced earlier in the week, previously reported by MABOnChain: an exit tax on crypto portfolios above 800,000 euros when taxpayers leave France, and an end to the tax deferral that currently lets holders swap Bitcoin into dollar-pegged stablecoins without triggering a taxable event from January 2027, at France's 31.4% flat rate. Taken together, the five amendments would tighten nearly every major way French holders accumulate, move or realize crypto gains.

Not law yet: the 31-3 vote

None of it is law. After adopting the crypto amendments, the Finance Committee rejected the revenue section of the broader 2027 budget bill by 31 votes to 3 on October 9, as MABOnChain reported. The National Assembly is scheduled to begin debating the revenue section on Tuesday, October 13, starting from the government's original draft, and the crypto amendments would need to be submitted again and approved during the proceedings before becoming part of the legislation, according to French tech publication Clubic. The bill would then still need to clear the Senate.
