The French tax authorities have been given a new tool to recover unpaid taxes from individuals who owe money. As of June 25, 2026, they can now directly address a crypto platform to obtain payment or forced sale of an individual's digital assets. This extension of the administrative seizure of assets held by a third party (SATD) to crypto-assets changes the situation for millions of bitcoin, ether, or stablecoin holders in France.
The SATD has existed for a long time for bank accounts, allowing the public accountant to require a third party, such as a bank or employer, to pay them directly the amounts they hold on behalf of a debtor. The law No. 2026-534 of June 25, 2026, relating to the fight against social and tax fraud, extends this mechanism to providers of crypto-asset services (PSCA), i.e., exchange platforms and approved brokers who hold digital assets for their clients.
Once the platform is notified, the debtor taxpayer has a deadline set by decree to sell the necessary assets and pay the sum due to the administration. If not, the platform proceeds to sell the positions sufficient to cover the debt, either directly if it is authorized to do so or by entrusting the operation to an approved provider. The seizure bears on the entire portfolio held on the day of the notification, within the strict limit of the amount due.
Only assets entrusted to a third party (platform, broker) fall within the scope. Personal portfolios escape the device. A holder who keeps their bitcoins on a private key or a hardware wallet (type Ledger or Trezor), without going through a platform, remains outside the scope of the SATD. The question arises, however, for users of crypto platforms now approved under the European MiCA regulation, which are the only ones authorized to operate in France.
This extension of the SATD does not occur in a vacuum. The tax authorities have been multiplying the traceability tools on crypto-assets for several months, while the gap between real gains and declared amounts worries the administration. At the same time, the confidentiality of tax data remains a point of vigilance, after the data leak that affected the DGFiP in 2026.
For a holder in compliance with their tax obligations, nothing changes; the device only targets debts already established and not regularized. For others, the arrival of the SATD on crypto platforms eliminates a blind spot: until now, a bank account could be seized, but a crypto portfolio hosted on a French platform actually escaped this type of direct recovery.
The new rules have implications for individuals with unpaid tax debts and crypto assets held on platforms. Taxpayers should be aware of the potential consequences of non-payment, including the forced sale of their digital assets. Platforms are also required to follow specific procedures when notified of a seizure, including limiting fees to 10% of the amount due.
Key points
- French tax authorities can now seize crypto assets from platforms to recover unpaid taxes.
- The extension of the administrative seizure of assets held by a third party (SATD) aims to combat tax evasion.
- Personal crypto portfolios are not affected by the new rules.
