Corporate tax audit: 2026 method

Updated March 2026 - Business tax audits are based on simple logic: the administration tests the consistency between your accounting, your declarations and your documents. In practice, the quality of the file matters as much as the technical background. A well-organized company does not experience control as permanent improvisation.

Depending on the case, the company may face:

• ▸a document inspection;
• ▸an accounting audit;
• ▸a remote accounting exam.

The FEC remains central for companies subject to this obligation. But the real subject goes beyond the file: the documents, reconciliations and tax treatments must be readable and consistent.

• ▸VAT;
• ▸deductible expenses;
• ▸provisions;
• ▸remuneration and distributions;
• ▸intra-group flow;
• ▸concordance between packages, declarations and accounting.

Hayot Expertise Advice: A well-managed tax audit begins before the first letter. It begins the day you decide to produce accounts that can be reread without reconstructing the history of the company.

We prepare the files, organize the responses, reread sensitive points and secure the relationship with the administration during the inspection.
