France’s National Assembly has adopted a budget amendment that would make certain cryptocurrency-to-stablecoin conversions taxable from 1 January 2027.
The proposal would apply France’s 31.4% flat tax to qualifying gains realised when individuals exchange crypto assets for electronic money tokens linked to an official currency. This category includes certain fiat-backed stablecoins regulated under the European Union’s Markets in Crypto-Assets framework.
Although lawmakers adopted the amendment on 16 October, the measure is not yet law. It remains part of France’s proposed 2027 budget and must survive the remaining legislative process before taking effect.
Key Takeaways
- The proposed tax applies to qualifying gains, not the entire amount converted.
- It would cover exchanges from crypto assets into certain regulated fiat-backed stablecoins.
- The planned effective date is 1 January 2027.
- Other crypto-to-crypto exchanges would generally retain their existing treatment under the amendment.
- Adoption by the National Assembly does not mean the proposal has completed the legislative process.
What the Amendment Would Change
France currently allows many exchanges between crypto assets to occur without immediately triggering capital-gains tax. Tax generally becomes relevant when a person converts cryptocurrency into fiat currency or uses it to purchase goods or services.
The proposed amendment would narrow that treatment for conversions into qualifying stablecoins. Exchanging an asset such as Bitcoin for an eligible euro- or dollar-linked token could become a taxable disposal, even when the holder does not withdraw money to a bank account.
The change is intended to treat certain stablecoin conversions more like cashing out into conventional currency. Other exchanges between crypto assets would not automatically receive the same treatment.
UPay’s existing French crypto-tax guide explains the current reporting framework and how disposals are recorded. If the amendment becomes law, its final wording and implementation guidance would determine how that framework changes from 2027.
The Rate Applies to Gains, Not the Full Swap
The 31.4% figure refers to the proposed tax rate on the calculated gain. It should not be described as a charge on the complete value of every stablecoin conversion.
For example, suppose someone bought a crypto asset for €8,000 and later exchanged it for qualifying stablecoins worth €10,000. The economic gain would be €2,000 before considering the precise calculation method and any applicable rules. The headline rate would concern that gain rather than the entire €10,000 received.
Actual French calculations can depend on the taxpayer’s overall portfolio and circumstances. A simplified example therefore cannot determine an individual liability.
This distinction is important because crypto-tax systems vary considerably. Some jurisdictions already treat almost every crypto-to-crypto exchange as a disposal, while others defer taxation until assets are converted or spent. UPay’s wider collection of country-specific crypto-tax guides illustrates why users cannot assume that one country’s treatment applies elsewhere.
Why Transaction Records Would Matter
If stablecoin swaps become taxable, taxpayers may need to establish the euro value of the assets exchanged, their acquisition cost and the date of each transaction.
A wallet balance alone cannot provide all that information. Supporting records may include exchange histories, purchase confirmations, wallet transactions, fees and the market value recorded when the swap occurred.
Maintaining those records becomes particularly important when the same asset was acquired at different prices or moved between several wallets and platforms. The movement of an asset between wallets controlled by the same person should also be distinguished from a disposal to another party.
The proposal forms part of a broader movement toward closer oversight of digital-asset activity. UPay’s overview of crypto regulatory compliance explains how taxation, reporting and customer-verification rules can impose separate obligations.
What Happens Next?
The Assembly’s adoption does not guarantee that the amendment will appear unchanged in the final budget. The proposal remains subject to further consideration before the legislation can be enacted.
Taxpayers should therefore distinguish the proposed 1 January 2027 start date from a confirmed obligation. The final budget text and subsequent administrative guidance will determine which stablecoins qualify, how gains must be calculated and what reporting procedures apply.
Conclusion
France’s proposal would move qualifying stablecoin conversions closer to the tax treatment of cash disposals. Its most important practical effect would be to make a transaction potentially taxable before funds ever reach a bank account.
For now, the amendment represents an approved legislative proposal rather than a completed change in law. The final budget and implementation guidance remain the documents that will establish what French crypto holders must do.
