France’s Stablecoin Tax Plan Advances as Budget Vote Timing Shifts

French deputies have narrowly backed a proposal to tax gains on cryptocurrency conversions into single-currency stablecoins from January 2027. The measure still needs parliamentary approval, while The Defiant reports that the budget vote carrying it has moved to Nov. 3.

A narrow amendment vote, not a completed tax law

France’s National Assembly has approved a budget amendment that would make certain stablecoin conversions taxable without investors first withdrawing euros. According to CoinDesk, amendment I-3898 passed on Oct. 16 with 38 deputies supporting it, 37 opposing it and 25 abstaining. Its adoption advances the proposal but does not complete the legislative process.

The distinction matters for anyone assessing an immediate change to trading or accounting obligations. CoinDesk reported that the provision could still change or disappear during the budget’s remaining parliamentary stages. If enacted as described, it would cover transactions beginning Jan. 1, 2027, rather than impose an immediate tax on existing conversions.

Stablecoin conversions would cross the tax boundary

Under the current framework described by CoinDesk, cryptocurrency exchanges generally qualify for tax deferral when there is no additional cash payment. Decrypt explains that French holders can ordinarily exchange crypto assets without triggering tax until they cash out or spend. The amendment would create an exception for conversions into electronic money tokens under the European Union’s MiCA framework.

Decrypt describes that category as stablecoins tied to a single official currency. The important boundary is therefore the legal classification of the asset received, rather than simply whether a trader describes a transaction as staying in crypto. CoinDesk reported that receiving qualifying tokens could generate a tax obligation even when nothing reaches a bank account.

That changes the role of a stablecoin conversion in tax accounting. A transaction used to hold value within cryptocurrency markets would also become a point at which gains are recognized. It would not be necessary to leave the crypto market altogether for the proposed tax treatment to apply.

The calculation would change alongside the taxable event

The proposal reaches beyond which transactions trigger tax. According to Decrypt, the gain on a qualifying conversion would reflect the stablecoins’ value less the acquisition cost of the cryptocurrency exchanged. A portfolio-wide calculation would give way to costs attached to the particular asset disposed of.

CoinDesk independently describes the replacement method as a weighted average for purchases of the same cryptocurrency at different prices. Decrypt adds a transition rule for assets acquired before 2027: holders would make an irrevocable choice between substantiating actual acquisition costs and allocating their portfolio’s aggregate cost across holdings at December 31, 2026.

The rate also requires precision. CoinDesk reports a default capital-gains levy of 31.4%, with an option to use the progressive income-tax scale. Decrypt links the flat-rate increase from 30% to higher social charges under France’s 2026 social security financing law. The proposal concerns recognition and calculation of gains, not a levy on the entire amount converted.

The reports agree on substance but differ on the calendar

The outlets converge on the narrow amendment result and the proposed January 2027 start. Their accounts contribute different details: CoinDesk explains the tax framework and objections raised during debate, while Decrypt adds the transition election for older holdings and the surrounding committee proceedings.

The timetable needs a separate distinction. The Defiant’s Oct. 19 report placed the budget vote on Oct. 20, while Decrypt said the full revenue section was due for a Tuesday vote before the budget moved to the Senate. The Defiant’s Oct. 20 update instead reports that the budget vote carrying the stablecoin measure has moved to Nov. 3.

The Defiant’s later account changes the reported voting schedule, not the amendment’s stated substance. Its brief summary gives no reason for the postponement. The editorial distinction is between deputies having endorsed an individual provision and Parliament completing the broader budget process needed to enact it.

The dispute combines tax policy with practical traceability

Decrypt reports that the amendment’s sponsors, led by Nicolas Sansu, view stablecoin conversions as a gap through which gains avoid the flat tax. Their argument treats these tokens as investment and payment instruments whose use should not preserve the existing deferral. That is the sponsors’ rationale, rather than an established finding about every holder’s behavior.

Government opposition focused on implementation. According to CoinDesk, Public Accounts Minister David Amiel sought withdrawal of the amendment and raised the need to define stablecoins and trace portfolio reallocations. Finance committee rapporteur general Philippe Juvin favored retaining deferral because of cryptocurrency volatility.

CoinDesk also reported a warning from Chainalysis regional sales director Francois Volpoet that the change could steer investors toward decentralized finance, peer-to-peer dealings and offshore exchanges beyond international tax-reporting arrangements. That is a prospective concern, not evidence that such migration has occurred. It places enforceability alongside the debate over when gains should become taxable.

Final wording and acquisition records remain central

For holders and crypto service providers, the consequential details are the final token definition, the transaction rules and the acquisition-cost method. Purchase histories would matter under the asset-based calculation described by both full reports. Decrypt’s account of the irrevocable transition election makes historical documentation particularly relevant to the proposal’s eventual operation.

Separate proposals should not be confused with the stablecoin amendment. Decrypt also reported committee measures concerning crypto exit taxation and declarations of substantial self-custodied holdings. Those measures address different obligations and do not establish that the stablecoin provision has become law.

The next legislative developments to watch are the rescheduled budget vote, any revisions to the amendment and subsequent Senate consideration. The unresolved issue is whether the final legislation retains both the stablecoin exception and the revised cost calculation. Together, those provisions would determine which conversions recognize gains and how those gains are measured.

FAQ

Has France already enacted the stablecoin swap tax?

No. Deputies approved a budget amendment, but CoinDesk and Decrypt report that further parliamentary stages remain. The Defiant’s later report places the budget vote carrying the proposal on Nov. 3.

Would converting crypto into stablecoins require a bank withdrawal to trigger tax?

Not under the proposal described by CoinDesk. Receiving qualifying MiCA electronic money tokens could recognize a taxable gain even without a fiat withdrawal to a bank account.

How would acquisition costs be calculated?

The proposal would replace portfolio-wide accounting with costs tied to the assets exchanged, averaging purchases of the same cryptocurrency. Decrypt also reports an irrevocable transition choice for holdings acquired before 2027.
