Proposed French Stablecoin Tax Threatens to Drive Crypto Traders Offshore

France is considering sweeping changes to its digital asset taxation under the proposed 2027 budget, introducing measures that would tax crypto-to-stablecoin swaps and require mandatory disclosures for self-hosted wallet owners. CoinDesk reported that the measures have sparked industry warnings over potential capital flight.

Currently, France applies a 31.4% flat tax to crypto gains when investors cash out or spend their holdings, while swapping one cryptocurrency for another generally does not trigger capital gains tax. Under the amendments adopted by the National Assembly's finance committee on October 7, 2026, taxable events would expand to include swaps into EU-regulated stablecoins, with an effective date proposed for January 1, 2027.

What are the specific reporting and tax thresholds?

The proposed framework introduces strict declaration requirements and extended tax measures for digital asset holders in France. According to CoinDesk and Crypto Economy, the key financial and compliance thresholds include:

• Self-Hosted Wallets Declaration: Mandatory disclosure for holders with at least €100,000 (~$116,000) in assets, carrying fines up to $11,600 for non-compliance.
• Exit Tax Extension: A threshold of roughly $900,000 in crypto holdings.
• Loss Carry-Forward: Up to 10 years for taxpayers.
• Taxable Onchain Activity: Chainalysis data for 2025 estimated $9.4 billion in taxable onchain crypto activity in France, including $2.5 billion in gains.

Francois Volpoet, identified as Chainalysis' regional sales director for France by CoinDesk (and as CEO for France by various aggregators), questioned the efficacy of the proposal in an email statement. "Do we want more taxpayers to declare their assets, or a higher tax rate applied to a base that is increasingly evaded?" Volpoet asked, warning that the rules could push investors toward decentralized finance platforms, peer-to-peer trading, and offshore exchanges.

Why are security concerns being raised?

Industry participants have highlighted physical security risks associated with mandatory asset disclosures. Crypto Economy reported that Europe recorded 39 of 52 global physical attacks—often referred to as wrench attacks—in the first half of 2026, with France accounting for 33 of those incidents (63.5% of the worldwide total) or 46 total attacks leading to over $30 million stolen. During the first half of 2026, 30 violent attacks occurred in France, with over 40% targeting relatives of crypto holders. Volpoet raised specific security concerns regarding the forced disclosure of self-hosted wallet assets against this backdrop.

What happens next in the legislative process?

None of the measures have become law yet. On October 9, 2026, the finance committee backed the proposal requiring the declaration of self-hosted wallets, but the broader revenue section of the 2027 budget was rejected by the finance committee by a vote of 31 to 3. Consequently, the crypto amendments must be resubmitted for debate.

The full National Assembly is scheduled to vote on the budget's revenue section on October 20, 2026. Lawmakers face a final deadline of December 10, 2026, to pass France's 2027 budget.
