French Assembly Passes 31.4% Tax on Crypto-to-Stablecoin Swaps by One Vote

In a razor-thin vote that has sent shockwaves through Europe’s digital asset industry, France’s National Assembly has narrowly approved a legislative amendment to treat cryptocurrency swaps into single-currency stablecoins as taxable events. The contentious measure, adopted during ongoing budget deliberations by a margin of 38 votes to 37 with 25 abstentions, aims to dismantle the long-standing tax deferral benefit that crypto traders have relied upon to hedge against market volatility.

If enacted into law following subsequent legislative readings, the rule would subject French crypto investors to the country’s flat capital gains tax rate of 31.4%—combining a 12.8% income tax and an 18.6% social levy. The tax would trigger whenever a user trades volatile digital currencies such as Bitcoin or Ethereum into single-currency pegged tokens, even if no fiat cash is ever withdrawn to an external bank account.

Ending the Safe Haven: How the Measure Upends Crypto Trading

Under prevailing French tax regulations, conversions between digital assets enjoy tax neutrality, deferring tax obligations until funds are converted into sovereign fiat currencies. This framework has allowed both institutional operators and retail investors to swiftly move capital into fiat-referenced stablecoins during market downturns without incurring immediate tax liabilities or cumbersome administrative paperwork.

The newly approved proposal, spearheaded by lawmaker Nicolas Sansu, reclassifies single-currency stablecoins recognized as electronic money tokens (EMTs) under the European Union's Markets in Crypto-Assets (MiCA) regulation as economic equivalents of traditional currency. Proponents of the reform argue that because stablecoins such as USDC and regulated euro-pegged tokens are increasingly integrated into payment rails and commercial settlement, exchanging speculative assets into them represents an economic gain that should no longer escape state revenue collectors.

However, blockchain advocacy groups and market analysts warn that the move fails to account for the technical mechanics of on-chain liquidity. Forcing traders to calculate capital gains and losses on intra-portfolio conversions could severely hamper algorithmic trading desks, diminish liquidity across French digital asset service providers, and encourage domestic market participants to migrate toward offshore or decentralized platforms.

Government Resistance and the Legislative Road Ahead

The measure passed despite explicit resistance from the French executive branch and budget authorities. During the parliamentary debate, government representatives urged the withdrawal of the amendment, cautioning that its implementation would be excessively complex. Authorities highlighted the administrative burdens of tracking granular transaction histories across decentralized liquidity pools and verifying weighted-average acquisition costs.

Importantly, the vote within the National Assembly does not yet constitute final law. The finance bill must still navigate full chamber votes, review and scrutiny by the French Senate, and potential reconciliation sessions before formal promulgation. Industry representatives expect heavy pushback from conservative and pro-business lawmakers in the upper house, who may attempt to strike down or significantly rework the amendment before the final budget is codified.

Broader Ramifications for Europe’s Unified Crypto Framework

The legislative showdown in Paris underscores a growing friction across the European digital asset landscape. Although the EU’s MiCA framework has established unified regulatory standards, licensing requirements, and compliance obligations for crypto-asset service providers across all member states, taxation remains under sovereign national control.

Should France maintain this aggressive stance on stablecoin taxation, it risks provoking substantial capital flight toward other EU member jurisdictions—such as Germany, Luxembourg, or Malta—that provide more accommodating fiscal environments for interim digital asset holding. For the broader international community, the French assembly's tight vote demonstrates that while European regulatory oversight is crystallizing under MiCA, national treasuries are seeking aggressive methods to capture revenue from on-chain liquidity.
