France is weighing changes to its cryptocurrency tax regime that could bring stablecoin-to-stablecoin swaps into the scope of taxable events, The Cryptonomist reports.

Under the current French framework, retail investors pay tax on conversions of crypto assets into fiat currency, while crypto-to-crypto transactions have generally not triggered a taxable disposition. The reform under discussion would alter that treatment for stablecoins — tokens such as USDC and USDT that are pegged to fiat currencies and dominate trading liquidity across centralized and decentralized venues.

If enacted, the change would mean that a swap between two stablecoins, or between a stablecoin and another digital asset where a stablecoin is treated as a fiat-equivalent leg, could be recognized as a realization event. That would force French taxpayers to track the acquisition cost and disposal value of every stablecoin conversion, including on-chain activity through decentralized exchanges and self-custodied wallets.

Who would be affected?

The reform would fall primarily on French retail traders and active market participants. Stablecoins sit at the center of crypto market structure: they serve as the base pair for most trading, as collateral in lending protocols, and as the settlement rail for on-chain payments.

Industry participants have long argued that a swap between two dollar-pegged stablecoins produces no meaningful economic gain, since both sides of the transaction hold the same pegged value. Treating such conversions as taxable events would, critics contend, create accounting friction without raising significant revenue.

The operational consequences would be material. French users would need:

• Disposition-level records for every stablecoin swap, including on-chain transactions
• Cost-basis tracking across wallets, exchanges and DeFi protocols
• Annual declarations distinguishing taxable stablecoin conversions from non-taxable crypto-to-crypto trades

What happens next?

The proposal remains at the stage of reported tax-policy discussion rather than enacted law. Any change to the treatment of digital assets in France would follow the country's budget and finance legislative process, and would need to align with the existing regime administered by the French tax authority.

France has positioned itself as one of Europe's more active crypto regulatory jurisdictions under the EU's Markets in Crypto-Assets (MiCA) framework, and its tax treatment of digital assets is watched closely as a potential reference point for other EU member states. A move to tax stablecoin swaps could therefore carry significance beyond France's borders, particularly if peer jurisdictions follow suit in how they define realization events for pegged assets.

Market participants and tax advisers will be watching the French budget process for concrete legislative language, which would determine whether stablecoin-to-stablecoin conversions become taxable and from which tax year the change would apply.
