Tax audit: how to react to an audit

Updated March 2026 - A tax audit does not automatically mean an adjustment. On the other hand, it is always a moment when the documentary organization of the company or the taxpayer is tested. The right reaction is neither panic nor passivity. It is a clear method, based on your rights and your supporting documents.

The official documentation of the DGFiP distinguishes several frameworks:

• ▸check on documents;
• ▸accounting verification;
• ▸accounting exam;
• ▸contradictory examination of personal tax situation.

The charter of rights and obligations of the audited taxpayer recalls the guarantees applicable depending on the type of audit.

You must immediately check:

• ▸the nature of the control;
• ▸the targeted exercises;
• ▸the date of first intervention;
• ▸the requested documents;
• ▸and the issuing service.

In business, the quality of the FEC, supporting documents, VAT reconciliations and tax arbitrations is decisive. For an individual, the logic is the same: consistency between declaration, supporting documents and bank flows.

The DGFiP also recalls the existence of the right to make an error, which allows in certain cases to regularize an omission or inaccuracy without incurring the full level of penalties.

Hayot Expertise Advice: What is costly in a tax audit is not only the initial error. Above all, it is the inability to explain it, document it or correct it in time.

• ▸respond too quickly without rereading the pieces;
• ▸produce incomplete exports;
• ▸improvise a posteriori justification;
• ▸neglect response times;
• ▸ignore legal remedies.
