French Senate Splits 38-37 on Stablecoin Tax Break for Crypto Swaps

France's upper chamber has approved, by a margin of a single vote, an amendment that would remove tax liability on crypto-to-stablecoin swaps, but the provision now faces further legislative review before it can become law.

The Senate split 38 to 37 on the measure, which would exempt conversions between crypto assets and regulated stablecoins from the tax treatment that currently applies. The result shows how narrowly divided French legislators remain on digital asset taxation, and how much depends on individual attendance on voting day.

What does the vote actually change?

For now, nothing is final. The amendment has cleared the Senate, but the bill must pass through the remaining stages of the French legislative process before the tax relief takes effect. Practitioners advising French taxpayers should treat the vote as a signal of direction, not as a change in the law.

The core of the proposal is straightforward. Under current French treatment, swapping one crypto asset for another — including a regulated stablecoin — can trigger a taxable disposal. The amendment would carve out conversions into stablecoins that qualify as regulated instruments, on the logic that moving into a euro- or currency-pegged token is closer to a change of settlement vehicle than a realization of gain.

If enacted, the practical effect would be felt by retail and institutional traders who currently face a tax point every time they rotate positions into stablecoins to manage volatility or park collateral. For an active trader, a handful of such rotations per year can generate dozens of taxable events under existing rules.

Why the 38-37 margin matters

A one-vote margin in a chamber of several hundred senators indicates the measure passed with low attendance, which cuts both ways. It demonstrates that support exists for the principle. It also means the provision remains politically fragile: a differently composed session, or resistance in the lower house or in commission review, could reverse it.

The amendment's framing around "regulated" stablecoins is the operative constraint. Only conversions into tokens that meet the regulatory threshold would qualify. Market participants should expect definitional questions — which issuers, which reserve standards, which jurisdictions — to dominate the review stage, since those details determine whether the exemption covers a broad or narrow set of instruments.

What to watch next

The bill now moves to the next stage of the French legislative process, where the stablecoin carve-out can be amended, narrowed or struck. Advisers should monitor the commission and assembly schedules for the definitive text, and French taxpayers should continue applying current disposal rules to stablecoin conversions until the law is promulgated.
