1. France stablecoin tax clears the National Assembly by a single vote
French lawmakers have voted to tax the gains investors realize when they swap a cryptocurrency for a stablecoin, narrowing the gap between such trades and France's 31.4% capital gains rate. The National Assembly adopted amendment I-3898 to the 2027 budget on October 16 by 38 votes to 37, with 25 abstentions. If it survives the rest of the process, the rule applies to transactions from January 1, 2027.
The margin is the story as much as the measure. A single ballot separated approval from rejection, and a quarter of the chamber's recorded participants declined to take a side. That kind of result usually signals a provision that is far from settled, and the text itself still faces further parliamentary stages in which it could be amended or removed entirely.
The finance committee had already backed the proposal before it reached the floor, which gave the amendment institutional momentum. Even so, the government's representative in the debate asked for it to be withdrawn, setting up a dispute between parliament and the executive over how stablecoins should be treated by the tax system.
2. What does amendment I-3898 change?
Amendment I-3898 removes the tax deferral that currently applies when an investor moves from one crypto asset into a qualifying stablecoin. Specifically, it targets cases in which the investor receives an e-money token as defined under the European Union's Markets in Crypto-Assets regulation, known as MiCA. Those are the stablecoins that satisfy the bloc's licensing and reserve requirements.
The practical effect is that an investor could owe tax at the moment of the swap, even though no money has reached a bank account in euros or any other fiat currency. Under today's approach the gain stays untaxed until the holder eventually cashes out. Under the amendment, the move into a compliant stablecoin would itself become a taxable event.
The provision is narrowly drawn around MiCA-compliant stablecoins, which is notable because those are the tokens regulators in Europe have tried to encourage as a safer category. Taxing the entry point into precisely that category is one of the tensions critics have pointed to, and it helps explain why the debate drew so little consensus.
3. How are crypto swaps taxed in France today?
Under current French rules, an exchange of one cryptocurrency for another generally does not trigger tax as long as no additional cash payment is involved. The investor carries the gain forward, and the liability only crystallizes when the holdings are converted into traditional money or used to buy goods and services.
When a taxable gain does arise on a private investment, it is by default charged at 31.4%. Taxpayers can alternatively choose to be taxed under the progressive income-tax scale, which may be more favorable depending on their overall earnings. The amendment would not alter that choice; it changes which transactions count as taxable in the first place.
Deferral on crypto-to-crypto trades has been a defining feature of how individual investors manage their positions. Traders can rotate between assets, reduce exposure during volatile periods and park value in a stable instrument without producing a tax bill at each step. Removing deferral for one specific destination asset would alter that routine for anyone who uses stablecoins as a resting place between trades.
4. Why stablecoins sit at the center of the dispute
A stablecoin is a crypto token designed to hold a steady value, typically by being pegged to a currency such as the dollar or the euro and backed by reserves. Because of that stability, they serve as the main settlement and parking instrument in crypto markets. Traders move into them to step aside from price swings without leaving the blockchain ecosystem.
That role is exactly why the tax treatment matters. If swapping into a stablecoin becomes a taxable disposal while swapping into other tokens remains deferred, investors face a financial penalty for using the most common low-risk option in the market. The amendment therefore reaches well beyond a niche product and touches the everyday plumbing of crypto trading.
MiCA, the European Union's framework for crypto-assets, sets out how issuers of e-money tokens must be authorized and how their reserves must be managed. The French amendment borrows that legal category as its trigger, so the definition of a taxable swap would depend on whether the token received falls within the EU's own classification rather than on a separate national test. That choice ties the French tax base to European regulation and leaves non-compliant tokens outside its scope.
Supporters of taxing the swap can argue that a stablecoin behaves much like cash, so receiving one is economically close to realizing a gain. Opponents reply that the investor has not left the crypto system and has no cash with which to pay the resulting bill. The vote suggests that French lawmakers are almost evenly split between those two readings.
5. Government and committee positions
Public Accounts Minister David Amiel questioned how the rule would work in practice and asked for the amendment to be withdrawn, saying the government would oppose it if it were not. In the debate he argued that stablecoins must first be defined, and that the authorities need to be able to monitor and trace reallocations within a portfolio before taxing them.
That objection is administrative as much as political. A tax on swaps depends on the state being able to see them, value them at the time of the trade and attribute them to a taxpayer. Amiel's remarks indicate that, in the government's view, the definitional and tracing groundwork has not yet been laid.
Philippe Juvin, the rapporteur general of the finance committee, took the opposite side of the practical question and favored keeping the deferral because of the volatility that characterizes crypto assets. His argument points to the difficulty of assessing a gain at a moment when prices can move sharply within hours. The two positions show that disagreement runs through the institutions rather than simply dividing the government from the legislature.
6. Industry warning: DeFi, peer-to-peer trades and offshore venues
Francois Volpoet, regional sales director for France at the blockchain analytics firm Chainalysis, told CoinDesk that the proposal could push investors toward decentralized finance, peer-to-peer transactions and offshore exchanges that fall outside international tax-reporting arrangements. His concern is displacement: that a tax intended to capture activity might instead drive it to places where it is harder to see.
The argument rests on a familiar dynamic. Regulated platforms operating in Europe report customer activity to authorities under established rules, while decentralized protocols and some overseas exchanges do not. A levy that makes the regulated route more expensive can therefore encourage the very behavior that tax authorities find hardest to monitor.
Whether that outcome would materialize depends on how strongly investors respond to the new cost, and the available information does not quantify it. The warning nevertheless gives the amendment's critics a revenue-based argument as well as a market-structure one, since a rule that shrinks the visible tax base could collect less than expected.
7. A new method for calculating gains
The amendment also reaches beyond swaps. The text would replace France's current portfolio-wide method of calculating capital gains with one based on the acquisition cost of the assets that are actually sold. Rather than measuring the gain against the overall value of a holder's whole portfolio, the calculation would start from what was paid for the specific units disposed of.
Where an investor holds units of the same cryptocurrency bought at different prices, the text provides for a weighted average. That means the cost basis blends all purchases of the asset, so an investor who bought a coin at several price levels would use the averaged figure to determine the gain on a sale.
The change is technical, but it matters for anyone with a long trading history. Moving from a portfolio-wide approach to an acquisition-cost approach alters how gains and losses are computed, and combined with the end of deferral for stablecoin swaps it would make record-keeping an even bigger part of compliance for French crypto holders.
8. What happens next for the budget
The vote does not make the provision law. It is an amendment to the 2027 budget, and that budget still has remaining parliamentary stages to pass. Lawmakers can amend or delete the provision as the text moves forward, and the thin 38-37 margin gives opponents reason to try.
If it remains in the final text, the new treatment would begin on January 1, 2027, giving investors, exchanges and tax advisers a window to prepare. Platforms serving French customers would need to be able to identify swaps into MiCA-compliant e-money tokens and report them accurately.
Investors who hold positions across several assets may also want to review their records before the start date. Because the amendment links the taxable event to receiving a qualifying stablecoin, the timing of swaps near the end of 2026 and the beginning of 2027 could carry different consequences. Tax advisers typically urge clients to document the date, price and counterparty of every trade, and the proposed averaging method makes complete purchase histories more valuable still.
For now the outcome is open. The government has said it opposes the amendment, the finance committee's rapporteur favors the existing deferral, and industry voices have warned of displacement toward offshore and decentralized venues. Against that backdrop, the one-vote result on October 16 reads less as a final decision than as the start of a longer argument over how France should tax its stablecoin users.
