France backs stablecoin swap tax proposal

TLDR

Frances parliament has taken a key first step toward taxing swaps from crypto into fiat-pegged stablecoins from 2027, but the rules are not yet final.

1. French lawmakers Finance Committee approved amendments to tax crypto-to-stablecoin swaps from 1 Jan 2027, along with loss carryforward and exit-tax rules on large crypto holdings.
2. If enacted, moving into stablecoins could trigger capital gains tax even without cashing out to euros, tightening a popular parking strategy for French crypto users.
3. The full National Assembly still has to debate and vote on the 2027 budget; outcomes and details could change, and other EU states may follow different models.

Deep Dive

1. What France Just Backed

Frances National Assembly Finance Committee has approved several crypto tax amendments for the 2027 Finance Bill, including one that would treat conversions into fiat-pegged stablecoins as taxable events from 1 Jan 2027 if the bill passes. The amendment by MP Nicolas Sansu targets swaps into electronic money tokens under EU MiCA, closing what the explanatory text calls a legislative loophole where some crypto-to-crypto moves, including into stablecoins, did not crystallize tax. Gains would be calculated from acquisition cost, using a weighted average for units of the same token bought at different prices, according to committee reports and coverage of the approved crypto tax proposals.

A separate amendment allows realized crypto trading losses to be carried forward for up to 10 years, rather than just offsetting gains in the same year. Another adopted proposal would impose an exit tax on certain unrealized gains when households with more than 800,000 in crypto move their tax residence abroad, as detailed in Frances advances on stablecoin tax and loss relief.

2. Impact On Stablecoin Users And Market Behavior

For French residents, the key change is that swapping volatile crypto into fiat-pegged stablecoins could itself become a taxable disposal, even if funds stay on-chain or on an exchange. That would remove the current ability to lock in price moves via stablecoins without immediately triggering capital gains tax.

Combined with DAC8 reporting rules, which already require EU crypto service providers to collect and report detailed identity and transaction data to national tax authorities, France would have both better visibility and tighter rules on when gains are taxed. This could nudge some users toward longer holding periods, more precise record keeping, or using non-stablecoin hedging strategies, rather than frequent stablecoin parking. It may also influence which venues and structures French users prefer for their crypto exposure.

3. What To Watch Next In France And The EU

All of these measures are still proposals. The full National Assembly is scheduled to begin examining the 2027 Finance Bill in mid October, and the stablecoin swap tax, loss rules and exit tax could be amended or rejected during debate. Final scope, thresholds, and implementation details matter for how disruptive the rules become in practice.

Elsewhere in Europe, approaches differ. Greece, for example, is pursuing a draft law taxing realized crypto gains at a flat rate while leaving crypto-to-crypto swaps untaxed, as noted in the Greek crypto tax coverage. At the same time, ESMA is pushing stricter enforcement of MiCA against non-compliant stablecoins, which could further reshape which tokens and structures remain viable for EU users.

Conclusion

France is moving toward a regime where parking gains in fiat-pegged stablecoins would no longer be tax-neutral, while offering longer loss relief and taxing large unrealized gains on exit. For crypto users, the combination of tighter tax triggers, DAC8 reporting and EU-wide stablecoin supervision suggests a future where both strategy and venue selection need to factor in tax crystallization risk and regulatory status, not just price volatility.
