URSSAF control: how to prepare

Updated March 2026 - A URSSAF check is not necessarily a sign of fraud or a serious anomaly. This is a normal process for verifying compliance with the rules for collecting social security contributions. On the other hand, it is always a sensitive moment, because it very quickly reveals weaknesses in payroll, professional expenses, benefits in kind, contracts or HR documentation.

The control concerns the application of the rules relating to contributions and social security contributions. In practice, fréquent topics are:

• pay slips;
• bonuses and benefits;
• professional expenses;
• exemptions;
• treatment of managers;
• DSN compliance.

To place the subject in your organization, also consult our articles on HR and payroll obligations of the employer, on social, payroll and remuneration and on payroll outsourcing.

The inspection is in principle preceded by an inspection notice. The contradictory phase then requires responding to requests, transmitting useful documents and being able to justify the treatments chosen.

Article R243-59 regulates in particular:

• the prior notice;
• the scope of control;
• request for documents;
• the observations notified at the end of the inspection.

Article R243-59-1 also deals with control over dematerialized data.

Hayot Expertise advice: the best reflex is not to wait for the inspection to “put the file away”. Evidence must be organized as it arises: expense reports, agreements, proof of benefits and payroll documentation.

• payroll books and journals;
• DSN and supporting documents;
• employment contracts and amendments;
• documents on benefits in kind;
• expense reports and internal policies;
• agreements on managers or agents.

• think that the DSN is sufficient to demonstrate conformity;
• not being able to justify a benefit or reimbursement;
• neglect the documentation of professional expenses;
• respond too late or incompletely;
• treat control as a simple administrative subject while it involves the social qualification of flows.

In practice, inspections rarely focus on just one isolated line. The inspector is usually trying to see whether the payroll, expense reports, contracts and internal practices tell the same story.

The most common topics are:

• consistency between gross pay, net pay and the contribution base;
• professional expense reimbursements;
• benefits in kind or recurring bonuses;
• the status of directors and corporate officers;
• the accuracy of DSN filings;
• whether atypical treatments are backed by written support.

If one item is weakly documented, the inspection immediately becomes harder. If several areas are weak at the same time, the risk of adjustment increases quickly.

The process usually starts with a formal notice sent to the company. That lead time matters because it allows the business to gather documents and structure its response without improvising.

Once the inspection starts, the company needs to answer requests, provide useful documents and explain the treatments chosen. Article R243-59 covers the prior notice, the scope, document requests and the observations issued at the end of the inspection.

When data is available in dematerialized form, Article R243-59-1 also allows controls using automated processing. That means the company must be able to provide clean, readable and consistent files, not just printed slips.

The easiest way to get through an inspection without burning time is to keep a living evidence file throughout the year. That avoids hunting for documents at the worst possible moment.

Keep at least:

• payroll slips and payroll génération logs;
• DSN filings and consistency proofs;
• employment contracts and amendments;
• expense claims together with the applicable internal policy;
• supporting documents for benefits in kind;
• agreements or resolutions covering managers or officers;
• tracking tables for corrections and adjustments.

The file does not need to be fancy. It needs to be readable, dated and consistent. That is often what separates a controlled inspection from a painful one.

The end of the field visit does not mean the end of the matter. If an observations letter is issued, read it line by line, match each point with the available evidence and answer within the deadline.

A good response is not only about disputing items. It can also:

• provide a fuller explanation;
• fix an ambiguous présentation;
• supply a missing document;
• acknowledge a weak point and correct it going forward.

In some files, the best strategy is to distinguish a real error from a mere lack of proof. Those two situations should not be handled in the same way.

We can audit your risk areas, centralize the documents and prepare your responses before or during the inspection.

In 2026, a well-prepared URSSAF inspection is managed much better than a completed inspection. The key remains the same: quality of bulletins, consistency of flows and solid evidence file.
