France backs crypto wallet reporting rule above €100,000

• French lawmakers backed a proposal requiring declarations of qualifying self-custodied cryptocurrency wallets worth at least €100,000.
• The amendment forms part of France’s proposed 2027 Finance Bill and targets holdings valued on 31 December.
• The proposal could expand tax reporting obligations for crypto holders if Parliament approves the measure.

The French National Assembly’s Finance Committee has backed a proposal requiring declarations of self-custodied crypto wallets holding at least €100,000 in assets.

The measure forms part of France’s proposed 2027 Finance Bill and targets crypto holdings kept outside third-party service providers.

The amendment was filed by MP Charles de Courson, with Jean-Pierre Bataille and Michel Castellani also listed as sponsors.

Under the proposal, individuals and legal entities would declare qualifying wallets based on their combined crypto holdings’ value on 31 December.

The amendment also proposes penalties of up to €10,000 for failing to meet the reporting requirement.

Its explanatory statement cites concerns about undeclared cryptocurrency holdings and potential tax fraud as reasons for introducing the measure.

The proposal would bring certain self-custodied crypto holdings into a formal reporting framework, extending disclosure obligations beyond assets held through service providers.

The measure remains subject to France’s legislative process and would not become law unless Parliament approves it.
