France Passes Stablecoin Swap Tax by One Vote, Setting 31.4% Capital Gains Rate From 2027
The French National Assembly narrowly passed a 2027 budget amendment on October 17 that would impose a 31.4% capital gains tax on swaps from cryptocurrency into single-currency stablecoins. The measure passed by one vote and must clear additional legislative hurdles before becoming law.
A single vote separated French crypto holders from a sweeping new tax burden on Friday. The French National Assembly adopted a 2027 budget amendment on October 17 that would impose a 31.4% capital gains tax on every swap from cryptocurrency into a single-currency stablecoin, effectively dismantling the tax deferral treatment those conversions currently enjoy.
The amendment is not yet law. It must clear additional legislative hurdles before taking effect, but if it survives, the rules would apply from January 1, 2027.
The mechanics matter here. Under current French tax treatment, moving from Bitcoin into USDC or EURC is not a taxable event. The logic is that the holder has not realized a gain in any meaningful economic sense: they have merely parked value, not cashed out. The new amendment rejects that framing entirely. It would treat every such conversion as a disposal, triggering a 31.4% levy on accumulated gains at the moment of the swap. For a long-term Bitcoin holder using stablecoins as a routine risk management tool, the tax bill could arrive before they have touched a single euro of actual fiat.
That rate deserves context. France's standard flat tax on financial income, the "Prélèvement Forfaitaire Unique" or PFU, sits at 30%. The 31.4% figure applied here is slightly higher, a signal that lawmakers view stablecoin conversions not as neutral liquidity management but as a mechanism for deferring taxable gains indefinitely. The political framing is that stablecoin swaps function like a tax shelter, and the amendment is designed to close that shelter.
Critics of the measure push back on that characterization with force. Stablecoin conversions are frequently used for exactly the kind of defensive portfolio management that regulators elsewhere encourage: reducing volatility exposure during market stress, maintaining liquidity without fully exiting crypto markets, or managing collateral positions in decentralized finance protocols. Taxing those moves as disposals conflates risk management with avoidance. There is also a competitive dimension. France sits inside the European Union's MiCA (Markets in Crypto-Assets) regulatory framework, which has created a relatively harmonized licensing environment across member states, as seen in recent MiCA-driven market expansions across the continent. A punitive stablecoin tax that applies in France but not in Germany or the Netherlands creates an obvious incentive for French holders to route activity elsewhere, either to exchanges domiciled in other EU jurisdictions or to decentralized platforms where enforcement is structurally difficult.
The one-vote margin of passage underscores how contested the measure remains. Thin majorities in legislative chambers rarely signal durable policy. An amendment that scrapes through by a single vote is an amendment that a single vote could reverse at the next reading, and the French legislative process still gives opponents multiple opportunities to modify or kill the provision before it reaches the statute books. Whether the 31.4% rate survives those rounds intact, emerges diluted, or disappears entirely is genuinely open.
What is not open is the direction of travel. France has been steadily tightening its crypto tax framework since the PACT law in 2019, and this amendment fits a consistent pattern: each successive legislative cycle closes what policymakers identify as a new loophole. The stablecoin deferral question has surfaced in other jurisdictions too, and the broader debate over how stablecoins interact with traditional financial flows has attracted sustained attention from central banks and international regulators alike. France would be among the first countries to legislate a specific punitive rate on these swaps if the amendment clears its remaining hurdles.
For French crypto holders, the practical calculus is already shifting. At 31.4%, the cost of moving into stablecoins during a market downturn could easily exceed the losses avoided by doing so. That arithmetic will push some users toward either holding through volatility or seeking platforms outside French tax jurisdiction. Neither outcome obviously serves the revenue goals the amendment is meant to achieve.
The next legislative reading will be the one to watch.
