France proposes 31.4% tax on stablecoin swaps

TLDR

France is weighing a 31.4% capital gains tax on swaps from crypto into EU regulated stablecoins starting 2027, but the measure is still only a proposal.

1. The amendment would treat swapping crypto into MiCA regulated stablecoins as a taxable disposal at 31.4%, closing France's current crypto to crypto deferral rule.
2. Analysts warn the tax could push French users toward offshore venues or unregulated stablecoins, undermining efforts to concentrate activity in supervised EU markets.
3. The proposal sits in a wider 2027 tax package on self-custody wallets and exit taxes, with key votes pending and possible EU level crypto tax talks ahead.

Deep Dive

1. What Is Proposed

French lawmakers have drafted an amendment that would apply the existing 31.4% flat crypto capital gains rate to swaps from cryptocurrencies into stablecoins classed as electronic money tokens under MiCA from 1 January 2027. This would make exchanging bitcoin or ether into an EU regulated stablecoin a taxable event similar to selling for fiat, rather than a neutral portfolio move, and tax only the realized profit based on recorded acquisition cost, not the full swap value, as summarized in a CoinsKid community breakdown of the amendment.

The finance committee approved the change on 7 October, but later rejected the budgets revenue section, so the crypto tax measures must be refiled and passed by the full National Assembly, with a vote window running into December, according to a detailed Coindesk report.

Confidence: high, because multiple parliamentary and media sources describe the same amendment, rate and 2027 start date, while all stress it is not yet law.

2. Likely Market Impact

Today, crypto to crypto swaps in France generally do not trigger tax; applying 31.4% to swaps into MiCA stablecoins would make regulated hedging with onshore stablecoins much more tax expensive. Chainalysis Frances CEO warns that this could push traders toward unregulated or offshore stablecoins, DeFi routes and self hosted wallets that are harder for authorities to monitor, potentially fragmenting liquidity away from EU compliant rails.

Risk note: higher tax friction on hedging flows can reduce onshore depth in regulated stablecoins and widen spreads around French policy dates.

3. What To Watch

The stablecoin swap tax is part of a wider 2027 package that also proposes mandatory reporting of self custody wallets above 100,000 and an exit tax on households with more than 800,000 in digital assets when moving abroad. These measures remain proposals that must clear the full Assembly, and lawmakers are also discussing allowing crypto losses to be carried forward for up to ten years, which could soften the impact for active traders.

Separately, France is lobbying for EU level crypto taxes as part of the blocs 2028 to 2034 budget talks, suggesting that national rules like this could eventually tie into a broader European framework if other member states agree, as noted by TokenPost coverage.

Conclusion

Frances proposed 31.4% tax on stablecoin swaps would turn regulated crypto to stablecoin hedging into a taxable disposal, closing a popular deferral route and reshaping how French users manage risk with stablecoins.

If enacted, it could push activity toward less transparent channels and reduce liquidity on EU regulated venues, while the wider package on self custody reporting and exit taxes signals a broader tightening of Frances stance on crypto.

Until the 2027 budget is finalized, the proposal is a clear warning shot rather than a settled rule, and crypto users in France should treat upcoming parliamentary votes and future guidance as crucial milestones for how they structure their holdings.
