Tax Searches in France: What Really Happens During a Domiciliary Visit?

Why tax searches are rising in France

French tax authorities are using domiciliary visits and seizures—commonly called tax searches—more frequently in higher‑risk files.

In 2023, the number of domiciliary visits increased by 28.3%, from 127 to 163 operations, with 466 premises visited compared to 373 the year before.

Cases mainly involved undeclared activities (69%), underreported revenues or overstated expenses (27%), and declaration failures (4%).

This trend confirms that, in complex international tax disputes involving France, the administration no longer hesitates to enter homes and offices to secure evidence.

How a tax search is authorised and why it can be challenged

Tax searches are governed by Article L. 16 B of the French Tax Procedure Code.

Agents must be authorised by the Director General of Public Finances, who may delegate this power to the head of the National Tax Investigation Department (DNEF/NTIC) or their deputy.

In a recent case, the Paris Court of Appeal annulled a search because authorisations were signed by officials who did not actually hold the required NTIC director or deputy roles.

The court stressed that proper delegation of signature is a substantive safeguard and that failure to comply with authorisation rules harms the taxpayer.

In French criminal tax procedure , such defects can lead to the annulment of the judge’s order authorising the search and prevent the authorities from using seized documents to justify assessments.

What to expect during a domiciliary visit

A tax search is not a simple audit meeting; it is a coercive investigative measure ordered by a judge.

Agents may arrive early in the morning, enter your home, offices or professional premises, and seize physical and electronic documents, sometimes including data stored on servers or in the cloud.

You have the right to be assisted by a lawyer, but in practice many taxpayers are caught off guard and feel they must “cooperate blindly”.

In complex international tax disputes involving France, the seized material often concerns foreign accounts, crypto‑assets and cross‑border structures linked to crypto‑assets and foreign accounts

When a defective authorisation can save your case

In the Paris case, the taxpayer argued that the officials who signed the agents’ authorisations were not properly empowered.

Although the agents belonged to the right department, there was no proof that the signatories actually held the positions listed in the legal texts.

The Court of Appeal held that:

• the delegation of signature is an essential formality, not a mere technicality, and
• breaching this requirement makes the authorisation invalid and justifies annulling the judge’s order.

As a result, the seizure of documents was annulled and the administration could not use them to support reassessments, except to the extent independent sources existed.

For taxpayers, this shows how procedural flaws around tax searches can be a powerful lever when combined with broader work on procedural nullities in criminal tax cases

How tax searches fit into the broader criminal strategy

Tax searches usually occur in files where the authorities already suspect serious tax fraud, often after or alongside a referral to the French Tax Offence Commission (CIF).

They are used to secure evidence of undeclared activities, hidden accounts, or fraudulent invoicing circuits.

For UHNW individuals, executives and international families, what matters is not only whether the search was valid, but also how the seized material will be interpreted.

This includes questions of beneficial ownership, use of advisers and intermediaries and the line between planning and fraud, addressed in the article on tax fraud intent and reliance on advisers
