Are you facing a tax audit or have you just received a notice of tax verification? This stage is often sensitive for a business: tight deadlines, document requests, technical exchanges, and a risk of reassessment if certain points are not properly substantiated.
Yaël Sion LAWYERS & ASSOCIATES, a tax lawyer in Marseille, supports businesses and individuals at every stage of a tax audit to secure the process, structure your responses and protect your interests in dealings with the tax authorities.
The firm assists clients in Marseille, the surrounding region, and remotely throughout France, depending on your case and the most efficient format for you.
Why work with a tax audit lawyer?
A tax audit is not only about bookkeeping: it is also about strategy, the quality of supporting documents, the consistency of explanations and control of deadlines. The goal is not to “say more”, but to answer better, at the right level, with the right documents.
- Control deadlines and avoid improvised answers.
- Organize document production and frame communications with the authorities.
- Secure sensitive points (qualification, documentation, tax consistency).
- Prepare what comes next: closing meeting, potential reassessment, response strategy.
When should you contact the firm?
As early as possible. In practice, legal support is useful at three key moments:
As soon as you receive the audit notice
Context review, priority setting, internal organization (contacts, timeline, validation process), and an initial review of risk areas.
During exchanges and document requests
Structuring responses, checking the consistency of the documents provided, and securing explanations (written and oral) to reduce misunderstandings or unfavorable interpretations.
At the closing stage and if follow-up action is taken (reassessment)
Preparing for the closing meeting, consolidating arguments, and supporting you if the authorities consider adjustments or issue a proposal for rectification.
Our approach
A tax audit should not be endured: it must be prepared for, structured and actively managed from the very first exchanges, in order to control the framework, limit exposure and retain control over the procedure.
Frame the matter: quickly identify the real stakes
Every tax audit has its own priorities. The firm helps you clarify what is truly under review, prioritize topics, and build a clear, defensible response strategy.
Secure: document properly, without over-sharing
The right reflex is not to “send everything”. We help you provide the relevant documents, at the right time, with an appropriate level of formalization, while keeping an exact record of what is transmitted.
Protect: control communications
Limiting the number of spokespersons, avoiding contradictions, and maintaining a factual, professional tone can directly influence how the audit unfolds. We help frame your written and oral communications.

FAQ - Tax Audit Lawyer
Does a tax audit automatically mean a reassessment?
No. A tax audit aims to verify the accuracy of filings and the consistency of the information provided. It can end with no tax adjustments if documents and explanations are deemed sufficient.
Why seek legal support if “everything is in order”?
Because the stakes are also procedural and methodological: deadlines, organization, quality of responses, and consistency of supporting documents. Legal support often helps avoid communication mistakes or poorly calibrated disclosures.
Do you work only in Marseille?
The firm is based in Marseille and also provides support remotely throughout France, depending on your situation and the most efficient organization.
Do you work with the company’s accountant?
Yes, when relevant. The firm can coordinate with your accountant and internal teams to secure both the production of documents and the response strategy.
What should we do right after receiving an audit notice?
Centralize information, limit the number of spokespersons, gather key documents, and frame a structured response strategy. A quick discussion with a tax lawyer helps secure the first steps.
