France’s tax proposal would tax Bitcoin

France's proposed amendment to crypto tax rules would allow recognition of gains or losses on swaps into MiCA e-money tokens before any cash withdrawal. This change targets disposals and exchanges from January 1, 2027, concerning moves from Bitcoin or Ether into certain stablecoins. The proposal modifies how the acquisition basis is calculated for crypto holdings, offering investors a choice between using actual acquisition costs or an allocation method based on portfolio value.
The amendment seeks to remove the exchange deferral typically applied to crypto-to-crypto exchanges when converting to fiat or other goods, specifically when receiving e-money tokens defined under MiCA. This means that swapping assets like Bitcoin for qualifying stablecoins could trigger a taxable event immediately, rather than deferring taxation until a cash withdrawal occurs.
The proposed basis calculation focuses on the actual assets disposed of, specifying weighted-average acquisition values for assets of the same nature, replacing the current portfolio-based allocation. For holdings acquired before 2027, investors can choose between using actual costs or an allocation route based on valuation as of December 31, 2026. The structure aims to ensure that a swap itself recognizes potential gains immediately, and the basis reset mechanism is designed to prevent repeated recognition of prior gains upon later transactions.

* France’s committee-approved amendment would recognize gains or losses on swaps into MiCA e-money tokens before any cash withdrawal.
* The provision applies to disposals and exchanges from January 1, 2027, if enacted.
* A swap of Bitcoin exposure into USDC could result in recognizing a gain prior to cash withdrawal.
* The amendment targets the asset received, invoking MiCA definitions without an express issuer-licensing condition.
* Covered crypto-to-crypto exchanges without cash balancing payment receive tax deferral under existing guidance.
* The amendment removes the exchange deferral when receiving e-money tokens or related rights.
* Taxable swaps would reset received tokens’ basis.
* A hypothetical swap of Bitcoin into USDC could result in the USDC receiving €60,000 of basis under either transition route.
* An investor could use actual acquisition costs for older holdings, or allocate portfolio acquisition price calculated under old rules as of December 31, 2026.
* The proposed change does not rewrite the existing crypto loss restriction regarding offsetting losses within the same tax year.

The core tension in this legislative proposal lies between recognizing the immediate economic reality of a swap versus maintaining existing structures designed for deferred taxation and asset segregation. The mechanism shifts the focus from cash movement to asset transformation, aiming to eliminate what sponsors view as a legislative loophole related to fiat-backed stablecoin conversions.
The shift in basis calculation—from portfolio-wide allocation to asset-specific cost or weighted averages—introduces significant complexity regarding historical equity recognition. The choice between using actual costs versus the stipulated allocation method for pre-2027 holdings is not merely procedural; it fundamentally alters how realized gains are sequenced across transactions, as demonstrated by the hypothetical scenarios where different routes yield different net gains upon later disposal. This introduces a layer of decision-making that directly impacts investor sequencing and timing of tax liability.
The distinction between deferred exchange rules and taxable exchanges highlights a systemic desire to align regulatory treatment with transactional reality for crypto assets entering the stablecoin space, leveraging MiCA definitions as the specific trigger rather than relying solely on cash flow events. The concern is whether simplifying the mechanics of swaps inadvertently creates new avenues for timing gains that bypass existing loss-offsetting rules, even if the framework explicitly states no such intent. The real impact resides in how future portfolio management strategies are forced to account for asset basis reset across the entire lifecycle, moving from a simplified deferral system to an explicit, chosen recognition regime.
Bridge Questions: If the historical cost route results in higher realized gains under specific scenarios, what is the political or economic rationale for favoring deferred recognition over immediate recognition? How does the irrevocable nature of the allocation option affect long-term investment strategy compared to dynamic actual cost tracking? What are the unintended consequences if the recognized basis timing creates opportunities for sophisticated layering across different asset classes?
