French Parliament Backs 31% Capital-Gains Tax on Stablecoin Trading

France’s parliament has approved a measure that would subject certain stablecoin transactions to a 31% capital gains tax, marking a potentially significant change in how digital-asset activity is treated under the country’s tax framework.

The measure, identified as Amendment I-3898, removes a tax-deferral provision for stablecoins that comply with the European Union’s Markets in Crypto-Assets Regulation, commonly known as MiCA. The change is scheduled to take effect in January 2027.

Stablecoins are digital tokens designed to maintain a relatively stable value, typically by tracking a fiat currency such as the euro or the US dollar. Unlike more volatile cryptocurrencies, they are often used as a means of transferring funds, settling trades or temporarily holding value within digital-asset markets. Their treatment under tax law has therefore been closely watched by investors, exchanges and companies developing blockchain-based payment services.

The parliamentary vote means that the existing deferral available for qualifying MiCA-compliant stablecoins would no longer apply once the provision takes effect. As a result, transactions that previously benefited from postponed taxation could become taxable under the capital-gains regime at the stated rate.

The amendment does not appear to change the basic purpose of MiCA itself. The EU legislation establishes regulatory requirements for crypto-asset issuers, trading platforms and service providers, including rules covering stablecoins. Instead, the French measure addresses how assets falling within that regulatory framework are treated for tax purposes.

That distinction is important. Regulatory compliance and tax treatment are separate issues: a stablecoin may meet European market rules while still being subject to national tax obligations. By linking the removal of the deferral to MiCA-compliant stablecoins, the amendment places a category of regulated digital assets directly within the scope of the proposed change.

The 2027 start date gives investors and businesses time to assess the consequences before the new approach is implemented. Market participants may need to review how they record acquisitions, disposals and exchanges involving stablecoins, particularly where those transactions have historically been treated as deferred rather than immediately taxable events.

The practical impact will depend on the final application of the provision and on how French tax authorities interpret transactions covered by the amendment. The available information identifies the removal of the deferral and the 31% capital-gains rate, but does not set out every reporting requirement or explain how the rule would apply to all possible uses of stablecoins.

For individual investors, the change could affect decisions involving the conversion of one digital asset into another, transfers between platforms and the use of stablecoins as a cash-like position within a crypto portfolio. Businesses could face separate considerations when using such tokens for payments, treasury management or settlement. Those effects cannot be fully assessed without further details on the measure’s implementing provisions and the circumstances in which a taxable gain would be recognized.

The amendment also highlights a broader policy question facing European governments: whether stablecoins should be treated mainly as investment instruments, payment tools or a hybrid of the two for tax purposes. Their design allows them to function differently from conventional cryptocurrencies, but their use in trading markets can still produce gains and losses that tax authorities may seek to capture.

France’s decision comes as European regulators and national governments continue to refine the relationship between digital-asset regulation and existing tax systems. MiCA provides a common regulatory framework across the European Union, but taxation remains largely a national responsibility. That leaves individual member states with room to establish their own rules for reporting, deductions, exemptions and the timing of tax recognition.

For now, the central change approved by parliament is clear: the tax deferral for MiCA-compliant stablecoins is set to disappear from January 2027, while transactions falling within the measure would face a 31% capital-gains tax. Investors and crypto businesses operating in France will likely need to monitor subsequent legislative and administrative guidance before determining how the rule will affect their specific activities.
