French MPs Back a Stablecoin Tax Amendment, Not a Final Law

MPs approve an amendment, not a final law. The proposal could change tax timing and acquisition-cost records for affected crypto exchanges.

French MPs approved an amendment on 16 October 2026 that would change the tax treatment of exchanges into certain stablecoins. The distinction that matters for a beginner is procedural: a vote on an amendment during the first reading of a budget bill is not the same as a completed law already applying to transactions.

Three key points

• The official record shows amendment I-3898 adopted by 38 votes to 37, with 25 abstentions.
• The proposal targets exchanges into electronic-money tokens and also changes how acquisition costs would be calculated.
• Its proposed start date is 1 January 2027; final enactment and the final text remain separate questions.

What the official documents establish

The National Assembly’s vote record identifies a public-session vote on Nicolas Sansu’s amendment during the first reading of the 2027 finance bill. The amendment itself, tabled on 10 October, is marked adopted on 16 October. Journal du Coin’s 17 October report also distinguishes this stage from final adoption of the legislation.

The text would remove the exchange-tax deferral for transactions in which the seller receives electronic-money tokens as defined by the EU’s MiCA regulation, or related rights. The legal definition matters: a convenient label such as “stablecoin” should not replace checking the actual category covered by a rule.

The proposal also rewrites acquisition-cost rules, including a weighted-average approach for assets of the same type bought at different prices. It includes transitional choices for assets acquired before 2027. Those are proposed rules within the amendment, not a statement of a taxpayer’s current obligations.

Why the timing of a tax event matters

A stablecoin is a crypto-token designed to track a reference value, often a currency. Moving from a volatile token into a currency-linked token can change market exposure without putting ordinary money into a bank account. That does not necessarily mean no economic gain has been realised.

If legislation makes that exchange taxable, a person could need to account for a gain while still holding tokens. The practical effects could include record-keeping costs, a need to identify acquisition values and a mismatch between the asset held and the currency needed to settle a tax bill. These are general consequences of the proposed mechanism, not a calculation of anyone’s tax liability.

The tax base also matters. A tax on a gain is different from a tax on the full value exchanged. Fees, acquisition costs and the applicable rules determine the relevant calculation. This article deliberately does not apply a headline tax percentage to a simplified portfolio: the final law and individual circumstances would be necessary for a reliable calculation.

What could change for platforms and users

Trading platforms and tax-software providers could need to adapt transaction classifications and reporting if the proposal becomes law in this form. Users could need consistent records across services and wallets. A new reporting requirement can therefore have costs beyond the amount of tax eventually payable.

A stablecoin also continues to carry its own risks, including redemption arrangements and the possibility of trading away from its reference value. A tax classification does not guarantee a token’s safety or turn it into a bank deposit. Equally, the French vote does not demonstrate an effect on Bitcoin’s price or establish a worldwide tax rule.

What to watch next

Follow the final legislative text, whether these provisions survive the remaining process and any official implementation guidance. The date written in the amendment is conditional on legislation taking effect; it is not proof that the rules have already changed. This is an explanation of a verified parliamentary step, not personal tax or investment advice.
