## Securing your position in the most sensitive tax disputes

Tax disputes involve significant financial, reputational, and strategic stakes. Tax audits, reassessments, searches, and judicial proceedings each require a technical and strategic defense to safeguard your rights.

We intervene at every stage, including assistance during audits, defense in the context of searches and seizures, administrative proceedings before the tax authorities, judicial litigation, and the handling of matters combining tax and criminal aspects.

Our approach combines mastery of tax procedures, in-depth knowledge of the internal functioning of the tax authorities, and a clear understanding of operational realities. We advise French and international companies, executives, shareholders, and investment funds. Working in close coordination with our white-collar team, we ensure a comprehensive and consistent defense strategy.

### (01) Tax Audits and Investigations

We assist clients during tax audits, accounting reviews, personal tax examinations, and desk audits. Our involvement includes analyzing requests from the authorities, preparing detailed and reasoned responses, negotiating with tax inspectors, and challenging reassessment proposals.

We anticipate potential reassessment risks, structure exchanges with the authorities, and safeguard our clients’ positions. This proactive approach limits tax exposure and helps prevent escalation into formal litigation.

### (02) Tax Searches and Investigative Procedures

Tax searches require immediate action to protect the rights of those concerned. We intervene on an urgent basis during investigative operations, assist executives and employees during questioning, challenge procedural irregularities, and ensure proper handling and preservation of seized documents.

Our knowledge of procedural safeguards and experience in investigative contexts help protect fundamental rights and mitigate the consequences of these intrusive measures.

### (03) Administrative Tax Litigation

We represent clients at all stages of administrative tax proceedings, including preliminary claims, hierarchical appeals, and appearances before tax commissions. Our strategy is aimed at securing full or partial relief from contested assessments through robust legal and factual argumentation.

Where appropriate, we also negotiate settlement solutions with the tax authorities when they better serve our clients’ interests. Mastery of administrative procedures maximizes the prospects of success and reduces the risk of escalation.

### (04) Judicial Tax Litigation and Criminal Tax Matters

We represent clients before all courts, including administrative courts, courts of appeal, the Conseil d’État, and criminal courts. Our expertise covers disputes relating to the assessment, calculation, or collection of taxes, as well as prosecutions for tax fraud.

In coordination with our white-collar crime team, we provide a comprehensive defense in matters combining tax and criminal issues. This integrated approach ensures strategic consistency and optimal protection before tax and criminal authorities.

Collective excellence

at the service of the

*highest standards.*
