French lawmakers are currently debating a budget amendment that would require taxpayers to report any crypto assets held in self-custody wallets if the total value exceeds €100,000. While the measure has gained initial backing, it must still navigate the final 2026 budget approval process before becoming law. If enacted, it would represent a significant shift in how European regulators monitor 'unhosted' wallets, which have historically enjoyed a higher degree of privacy than exchange-based accounts.
The push for this regulation stems from a desire to close the tax gap and prevent wealth concealment in the decentralized finance (DeFi) space. Currently, most reporting requirements focus on assets held by Virtual Asset Service Providers (VASPs). By targeting private keys and hardware wallets, the French government is signaling that the era of anonymous high-value storage is coming to an end in Western Europe. The $112,000 threshold suggests the government is specifically targeting whales and institutional-grade retail investors.
For US-based investors and global market participants, this move is a critical indicator of the regulatory climate in the European Union. France often serves as a legislative bellwether for the broader EU under the Markets in Crypto-Assets (MiCA) framework. If this reporting requirement proves successful in France, it could set a precedent for other member states to adopt similar disclosures for private wallets, potentially influencing future US Treasury or IRS reporting standards regarding self-custody.
Investors should closely watch the finalization of the French budget in the coming weeks to see if the amendment survives in its current form. Additionally, the market should monitor the technical implementation: it remains unclear how the French tax authorities intend to verify holdings in non-custodial wallets without infringing on user privacy or demanding access to private keys. Any friction in this process could lead to capital flight from the French crypto ecosystem into more privacy-friendly jurisdictions.
