Stablecoin Regulation: France’s 31% Tax Plan Explained - OneSafe

France has proposed applying a 31% flat tax to gains from stablecoin transactions, according to reporting from OneSafe. The plan would treat certain stablecoin-related gains as taxable income rather than applying the lighter treatment often associated with conventional currency exchange. Because stablecoins are typically designed to hold a steady value against a reference asset such as the dollar or euro, the proposal raises a practical question: how much taxable gain can actually arise when price movement is minimal by design?

The market relevance lies in precedent and signaling. France has been active in shaping digital-asset rules, and a tax treatment this specific could influence how other jurisdictions frame their own stablecoin regimes. It also matters for holders who use stablecoins for settlements, treasury management, or as collateral, since a flat rate applied broadly could raise compliance costs and reporting obligations.

What to watch: whether the measure advances into final law, how gains are defined and calculated, and whether exemptions or thresholds emerge for low-margin transactions. Clarity on these points will shape how stablecoin activity is treated across Europe.
