France Moves to End the Tax Deferral on Crypto-to-Stablecoin Swaps From 2027

French lawmakers have taken a big step toward ending one of crypto’s most popular tax breaks: the National Assembly’s Finance Committee has backed a proposal that would end the tax deferral on swaps between Bitcoin and other cryptocurrencies and regulated stablecoins, meaning those trades could trigger a taxable event from January 1, 2027.

According to reporting by TokenPost, the committee adopted the measure as part of the sprawling 2027 Finance bill, and multiple outlets including CryptoRank and TronWeekly report the gains would be taxed at France’s flat 31.4 percent capital gains rate. For everyday investors, the change is straightforward: swapping Bitcoin into a euro- or dollar-backed stablecoin would no longer be a neutral “parking” move — it would count as a sale, and the taxman would want his share. Bitcoin was trading around 81,100 USD at the time of writing, according to the site’s price snapshot.

The Tax Break That Could Disappear

Here is how the current system works, in plain terms. In France, when you swap one crypto asset for another — say Bitcoin for Ethereum — you generally do not pay tax at that moment. The tax clock only starts when you cash out into regular money. Think of it like moving funds between accounts at the same bank: nothing is owed until you actually withdraw.

The new amendment, numbered I-CF1826 and adopted by the Finance Committee on October 7 according to CoinGeek, would remove that deferral for a specific kind of trade: exchanges where the investor receives qualifying fiat-backed electronic money tokens — in plain English, regulated stablecoins. From January 1, 2027, those conversions would be brought within the capital gains tax calculation. A stablecoin swap would be treated like a sale, even if you never touched a bank account.

• The trigger — swapping crypto into regulated, fiat-backed stablecoins would become a taxable event under amendment I-CF1826.
• The rate — multiple reports put the tax at France’s flat 31.4 percent rate on crypto capital gains.
• The start date — January 1, 2027, if the measure survives the parliamentary process.
• The status — adopted in committee, but not yet law (more on that below).

Why Stablecoins Are the Target

Stablecoins have become the crypto market’s version of cash under the mattress. They are digital tokens pegged to traditional currencies, and many investors use them to sit out volatility without officially “exiting” crypto. Regulators around the world have spent 2026 paying closer attention to exactly that behavior, from the EU’s MiCA rulebook to the United States’ GENIUS Act framework for issuers.

France’s move fits a pattern. As CoinGeek reported, the same Finance Committee adopted a package of digital asset tax amendments in recent days, including a requirement to declare self-custody wallets worth 100,000 euros or more and an exit tax on unrealized gains above 800,000 euros for those leaving French tax residency. The stablecoin amendment is the piece aimed squarely at ordinary traders: it closes the gap between “I moved my money to safety” and “I sold.”

The Catch: Nothing Is Final Yet

Here is where investors need to be careful with the headlines. According to CoinGeek, while the digital asset amendments were adopted in committee, the committee rejected the revenue section of the broader bill by a vote of 31 to 3. That means the crypto tax measures must be resubmitted and approved during full parliamentary proceedings before they become part of the legislation. In other words, the direction of travel is clear, but the destination is not guaranteed.

That distinction matters. A “committee backs” vote is a strong signal of political will — the amendments clearly have support among the finance lawmakers — but French budget politics are famously messy, and provisions can be amended, delayed, or dropped entirely during floor debates. TokenPost’s report that the Assembly has now backed the deferral-removal proposal suggests momentum, but nothing changes for taxpayers on day one.

What This Means for Your Portfolio

If you are a French investor, the practical takeaway is planning, not panic. First, the earliest start date is January 1, 2027 — swaps made before then would fall under the existing rules, so the second half of 2026 becomes a natural window to review positions. Second, if you routinely rotate into stablecoins during rough patches, understand that this habit may soon carry a tax cost each time you do it. Third, keep records: if every stablecoin swap becomes a taxable event, you will need to document dates, amounts, and prices for each one.

For investors outside France, the story is still worth watching. France has often been ahead of the pack on crypto enforcement within Europe, and tax authorities elsewhere study these playbooks closely. A rule that taxes stablecoin swaps as sales could easily migrate to other jurisdictions looking for revenue as crypto adoption grows.

The Verdict

France is signaling that the era of tax-free “parking” in stablecoins may be coming to an end, at least for its residents. The Finance Committee has backed ending the deferral on crypto-to-stablecoin swaps from 2027, with gains taxed at a reported flat 31.4 percent — but the measure still needs to clear the full parliamentary obstacle course after the committee rejected the bill’s revenue section. Watch the plenary debates before making any moves, and if you trade in size, this is a good week to talk to a tax professional.
