SKN | France Advances 31.4% Tax on Crypto-to-Stablecoin Trades as 2027 Budget Debate

Key Points:

• France’s National Assembly approved Amendment I-3898 by 38 votes to 37, with 25 abstentions, proposing to end tax deferral for certain cryptocurrency-to-stablecoin transactions.
• The measure would apply from January 1, 2027, and could expose qualifying transactions to France’s reported 31.4% flat tax on capital gains.
• The proposal remains subject to the wider budget process, raising questions about tax compliance, stablecoin usage and the future behavior of French crypto investors.

France has taken a significant legislative step toward changing the tax treatment of cryptocurrency transactions, with lawmakers approving an amendment that would make certain crypto-to-stablecoin exchanges taxable events. The proposal, reported by CoinDesk on October 20, 2026, would remove an existing tax deferral for qualifying stablecoins under the European Union’s Markets in Crypto-Assets Regulation (MiCA). If enacted, the change could affect how investors manage digital-asset gains from January 2027, even when they do not convert their holdings into euros.

Amendment I-3898 Targets Tax Deferral on Stablecoin Conversions

Amendment I-3898 was adopted by France’s National Assembly by a narrow margin of 38 votes in favor and 37 against, with 25 abstentions. The proposal forms part of the country’s 2027 budget process and seeks to change the treatment of transactions in which investors exchange cryptocurrencies for qualifying electronic money tokens under MiCA.

Under the existing framework described in the report, exchanges between crypto-assets can generally benefit from tax deferral when no additional cash payment is involved. Investors may therefore move between eligible digital assets without immediately triggering capital gains taxation, subject to applicable rules. The amendment would remove that deferral for the stablecoin transactions it covers.

If the proposal becomes law, investors could face a taxable event when converting an appreciated cryptocurrency into a qualifying stablecoin, even if the proceeds remain within the digital-asset ecosystem. The reported 31.4% rate reflects France’s existing flat tax on relevant private investment gains, although the final application of the proposed measure will depend on the legislation and its implementation.

MiCA Classification Could Determine Which Stablecoins Are Affected

The proposal’s reference to MiCA-defined electronic money tokens is central to determining its potential reach. MiCA establishes a regulatory framework for crypto-assets in the European Union, including stablecoins linked to official currencies. By tying the tax treatment to a specific regulatory category, the amendment would not necessarily apply identically to every token marketed as a stablecoin.

This distinction matters because stablecoins serve different functions in digital-asset markets. Investors use them to manage volatility, hold funds between trades and transfer value across platforms. If moving into certain regulated stablecoins triggers immediate taxation, some investors could reconsider how and when they realize gains.

The precise scope of the measure will depend on the final legal text and subsequent tax guidance. Investors should not assume that every stablecoin will receive identical treatment, particularly where a token’s regulatory status differs under the European framework.

Tax Compliance and Trading Behavior Under Scrutiny

The proposed change could influence trading practices beyond the immediate tax liability. If investors become liable for capital gains tax when moving into qualifying stablecoins, some may delay transactions, reduce trading activity or explore alternative ways to manage digital-asset exposure.

Industry representatives have also warned that stricter taxation could encourage some activity to migrate toward decentralized finance platforms, peer-to-peer transactions or offshore exchanges. Such an outcome is not inevitable, but it highlights a policy challenge: rules designed to improve tax collection may also change where and how transactions occur.

French policymakers must therefore weigh potential revenue and compliance objectives against implementation challenges. Public Accounts Minister David Amiel reportedly questioned whether authorities had sufficiently defined stablecoins and established the ability to monitor portfolio reallocations. The amendment’s eventual impact will depend not only on the tax rate but also on the clarity and practicality of the rules.

What Happens Before the Proposed 2027 Start Date?

Despite the National Assembly vote, the amendment has not yet become law. It remains part of a wider budget process and could be revised or removed during subsequent legislative stages. January 1, 2027, should therefore be treated as the proposed implementation date rather than a confirmed effective date.

For investors and digital-asset businesses operating in France, the next developments to monitor are the amendment’s status in the budget process, the final definition of covered stablecoins and any official guidance on calculating taxable gains. The outcome could influence portfolio management, trading volumes and the relative appeal of different stablecoin products in the French market.

More broadly, the proposal illustrates how governments are reassessing the tax treatment of digital assets as stablecoins become increasingly integrated into cryptocurrency markets. Whether France ultimately implements the measure will determine how significantly the change affects investors. Until the legislative process is complete, the distinction between an approved amendment and enacted law remains essential.
