When it comes to health insurance and death and disability cover, administrative management can sometimes feel like a puzzle. Yet the majority of the blocking situations we handle each month at MIA Assurances do not stem from the contracts themselves, but from simple configuration details in payroll or in the DSN.
Our teams have summarised the situations most frequently encountered with chartered accountancy firms and payroll managers.
The goal? Helping you secure your checks, save time and minimise corrective back-and-forth with the insurers. Here are the 7 crucial points of vigilance to build into your routines.
The most common configuration errors
- The breakdown of health and death-and-disability contributions
It is common to find that the distribution of rates in the payroll software is not perfectly aligned with the contractual documents. A quick check at the start of the year ensures the consistency and compliance of the configuration, thereby avoiding a heavy operational impact later on.
Field example: A company was applying an overall rate of 2.10%. However, after reviewing the contract, the correct breakdown required 1.40% for health and 0.70% for death and disability cover. The payroll configuration simply had to be adjusted to faithfully reflect the contract.
- The “Responsible” or “Non-responsible” configuration
The status of your contract has a direct and significant impact on certain reimbursement items (optical, dental) as well as on the applicable taxation. An incorrect configuration in your tool can generate major misunderstandings during URSSAF checks or reimbursements to employees.
Field example: A responsible contract was mistakenly configured as “non-responsible” in payroll. As soon as the correction was made, the reading of the guarantees and the processing of reimbursements became consistent again.
- Employee categories and applied rates
Aligning the configuration with the objective categories set out in the DUE (Employer’s Unilateral Decision) is absolutely essential to secure your social compliance. Whether it is the distinction between managerial and non-managerial staff or other hierarchical levels, payroll must be an exact mirror of the legal framework.
Field example: A DUE clearly distinguished managerial from non-managerial staff, but a single rate was applied by default in payroll. Adding a second rate restored a sound situation.
- DSN: the fields to monitor as a priority
The Déclaration Sociale Nominative (DSN) is the crux of the matter. Certain elements play a key role in the proper integration of contributions on the insurer’s side, notably the declaration structure, the affiliation to the body and the nature of the contributions.
Field example: The health contributions did appear in a client’s DSN, but without explicit affiliation to the relevant body. A simple update of this field enabled immediate integration, avoiding unnecessary automatic reminders.
- Updating contractual rates
Annual rate changes (often effective on 1 January) must be integrated without delay into your software. Any delay inevitably leads to billing discrepancies and the need to carry out time-consuming adjustments in the following months.
Field example: A death-and-disability rate had changed in January. The immediate integration of the new rate from the January payroll enabled the company to remain perfectly aligned with its renewal notice.
- Strict alignment between payroll and the DUE
We can never say it enough: the DUE remains the reference document. During our audits and validations, we sometimes observe discrepancies that appear minor but are completely blocking between what the DUE stipulates and what appears on the payslip.
Field example: A company’s DUE mentioned a mandatory option that was not identified in payroll. A simple clarification in the software configuration restored compliance.
- Consistency during work stoppages
Subrogation, payment of IJSS (Social Security Daily Allowances), transmission deadlines… A smooth and rapid coordination between the payroll department, HR and the insurer is the key to avoiding compensation delays that directly penalise your employees.
Field example: A death-and-disability claim was blocked pending the salary certificate. The responsive transmission of this document by the payroll department enabled immediate validation and release of the compensation for the employee.
