French legislators have taken a significant step towards taxing cryptocurrency transactions, specifically targeting swaps into stablecoins regulated under the EU's MiCA framework. This move, passed by the slimmest of margins, aims to close a perceived loophole where gains moved into stablecoins currently avoid France's flat tax, aligning France with similar policies in the UK and Italy.
Imagine you have special digital tokens, like arcade tokens, and you swap them for other special tokens that are always worth exactly one real euro. French grown-ups are now saying that when you make that swap, it's like you've "sold" your old tokens, and if you made a profit, you might have to give a small part of it to the government, just like when you sell a toy for more than you bought it.
Analysis
The National Assembly's Vote
The French National Assembly adopted a budget amendment by a razor-thin margin of just one vote, signaling a significant shift in the country's approach to cryptocurrency taxation. Out of 100 deputies participating, 38 voted in favor, 37 against, and 25 abstained, with the measure requiring exactly 38 votes for a majority. This narrow victory revives a proposal that had previously failed when the finance committee's broader budget text was rejected. The amendment, identified as I-3898, specifically targets the 2027 budget, indicating a forward-looking implementation. This legislative maneuver highlights the contentious nature of crypto regulation within French political circles, where opinions are clearly divided on how to best integrate digital assets into existing financial frameworks. The close vote underscores the ongoing debate regarding the economic implications and fairness of taxing various crypto transactions.
MiCA-Regulated Stablecoins
The core of the amendment focuses on treating swaps from other cryptocurrencies into MiCA-regulated electronic money tokens as taxable sales. Currently, French holders can exchange cryptocurrencies without incurring tax liabilities as long as no euros are involved, with taxes only due upon cashing out or spending. The new rule, effective January 1, 2027, specifically targets stablecoins pegged to a single official currency, which fall under the European Union's comprehensive crypto rulebook, MiCA. Proponents, led by Nicolas Sansu of the left-wing GDR group, argue that stablecoins function as "entirely conventional investment vehicles" and that gains moved into them exploit a "hole in the legislation" to avoid France's flat tax. The amendment also revises the cost basis calculation, moving from a single portfolio figure to individual purchase prices for each coin sold, averaged for multiple purchases of the same asset. This change aims to provide a more precise and potentially more complex method for calculating taxable gains.
France's Crypto Tax Push
This stablecoin tax is part of a broader push by French lawmakers to enhance crypto taxation and regulation. Another proposal, currently facing industry backlash, would require holders to declare self-custodied crypto wallets valued at €100,000 or more at year-end, with substantial fines for non-compliance. This measure has drawn criticism from crypto figures who express concerns about data collection risks, citing past incidents like the 2025 abduction and mutilation of Ledger co-founder David Balland. The government, through Public Accounts Minister David Amiel, initially opposed the stablecoin measure, arguing for a clearer legal definition of stablecoins and the state's ability to trace portfolio reallocations. Despite this opposition, the amendment passed, indicating a legislative determination to move forward with stricter crypto tax policies. The entire revenue section of the budget, including these crypto measures, still needs to pass further votes in the Assembly and then the Senate before becoming law, suggesting that the final form of these regulations could still evolve.
Key points
- French lawmakers narrowly approved a budget amendment to tax crypto-to-stablecoin swaps from January 1, 2027.
- The measure passed the National Assembly by a single vote (38 for, 37 against, 25 abstentions).
- It targets swaps into MiCA-regulated electronic money tokens, which are stablecoins pegged to official currencies.
- The tax aims to close a perceived loophole where gains moved into stablecoins currently avoid France's flat tax.
- A separate proposal requiring declaration of self-custodied crypto over €100,000 faces industry backlash.
The implementation of clear tax rules for stablecoin swaps could bring greater regulatory clarity to the French crypto market, potentially encouraging institutional adoption and reducing legal ambiguities for investors. Aligning with other European nations like the UK and Italy might also foster a more harmonized regulatory environment across the continent.
The new tax could deter crypto innovation and investment in France, potentially driving users and businesses to more lenient jurisdictions. The increased complexity of calculating tax liabilities for individual assets, combined with proposals for declaring high-value self-custodied wallets, might also create a significant administrative burden and privacy concerns for crypto holders.
