In summary…
Group supplementary health insurance has been mandatory since the January 1, 2016. Almost all leaders have one, and conclude that they are in compliance.
The exemption from contributions on the employer's contribution is conditional : a regular founding act, a collective and mandatory nature that is genuinely respected, a contract that conforms to the specifications described as "responsible". If any of the three conditions are not met, the contribution reverts to being considered salary.
An URSSAF audit covers three calendar years. It's never just one month of contributions that's at stake, but three tax years that are reinstated, including any penalties.
«We’ve had a company health insurance plan since 2016, everything is in order.» They ask to see the document that established it: it either doesn’t exist, or it defines a category that the law doesn’t recognize. The insurance contract itself is valid; it’s the legal framework that isn’t, and that’s what the debt collector has come to examine.
1. "Responsible" is not a marketing argument
The word appears on the leaflets; what it governs is found in the Social Security Code.
A responsible contract adheres to specifications regarding minimum coverage and maximum limits: co-payment, daily hospital allowance without time limit, meal plans 100 % Health, regulation of excess fees according to the practitioner's adherence to controlled pricing practice schemes, prohibition of reimbursement of flat-rate participation and deductibles.
The status dictates two things. First, the additional solidarity tax under Article L. 862-4 of the Social Security Code: a reduced rate for solidarity-based and responsible contracts, and the full rate for others. Second, and most importantly, the social security treatment of the employer's contribution: the exclusion from the tax base under Article L. 242-1 requires that the benefits comply with Article L. 871-1.
Specifically. You pay €60 per month per employee. As long as the system is compliant, this amount is not considered salary. The day it is no longer compliant, This €60 becomes a benefit subject to contributions, both employer and employee., over the entire period under review. Negligible per unit; not at all when multiplied by the number of employees and by three financial years.
For the technician. Specifications: Article L. 871-1 of the French Social Security Code (CSS) and its decree of November 18, 2014, supplemented in 2019 for the 100 % Health baskets. Exclusion from the contribution base: Article L. 242-1, within the limits of Article D. 242-1 — 6 % of the annual ceiling plus 1.5 % of remuneration, without exceeding 12 % of the ceiling. Social security contribution of 8 % beyond ten employees, CSG and CRDS from the first euro.
Article 83, 1° quater of the French General Tax Code (CGI) allows for a capped deduction for supplementary pension contributions., However, the employer's contribution to "healthcare expenses" has been reintegrated into the employee's taxable income since 2013. Social and fiscal matters do not overlap.
2. The founding act: three paths, only one to choose
The insurance contract establishes nothing, it executes
A group plan is established through an agreement, a referendum ratifying a proposal from the employer, or a unilateral decision recorded in a document given to each employee. Unilateral decisions are the most common method used in SMEs, but also the most vulnerable: drafted once in 2016 and never rewritten, even though the rates, employer-employee contribution split, and benefits have changed. A document describing a defunct plan does not provide protection; it merely documents the discrepancy.
For the technician. Implementation methods: Article L. 911-1 of the CSS. Minimum coverage and employer contribution of at least 50% %: Article L. 911-7, resulting from the ANI of 11 January 2013 and the law of 14 June 2013, generalized on 1 January 2016.
A classic blind spot: Article 11 of the Évin Law of December 31, 1989, allows employees present during a unilaterally implemented plan to refuse to join if the plan is partly funded by them. This refusal is legal and does not affect the mandatory nature of the plan—provided it is documented in writing.
3. The objective category: the breaking point
This is almost always where the case gives way.
An employer can reserve a pension plan for a portion of their staff, but they cannot freely choose which one. The category must be based on one of the following exhaustively listed criteria: managers and non-managers as defined by the 2017 national interprofessional agreement which replaced the AGIRC references, supplementary pension salary brackets, position in industry classifications, and two narrower residual criteria.
Everything else is outside the scope of this: name list, seniority, performance, department of assignment. The most common scheme — a management system, a system for "team leaders and experienced technicians" — only holds true if the second title corresponds exactly to a level of the conventional classification, and not to an internally established list of names.
4. Exemptions and beneficiaries: what is being quietly dismantled
The mandatory nature of the obligation is proven by its exceptions.
A mandatory health insurance plan allows for exemptions. Some exemptions are mandatory regardless of what the employer may have stipulated: short-term contracts, very part-time work where contributions would consume an excessive portion of the salary, beneficiaries of the supplementary solidarity health insurance, and employees already covered as dependents by a mandatory group plan. Other exemptions exist only if the agreement specifically provides for them. In all cases, the exemption must be requested by the employee in writing and kept on file.
The dependents fall under a different logic: the legal obligation applies only to the employee. Extending coverage to the family is a choice, but a choice that must be made—mandatory for all, or optional, with the employer's contribution financing an optional guarantee not being eligible for the exclusion from the tax base.
- The founding act — Agreement, referendum minutes or unilateral decision, updated with rates and guarantees, with proof of delivery.
- The category — The objective criterion retained, linked to a text: industry classification, salary bracket, executive status.
- Non-members — A written request for exemption and its supporting document, for each employee not covered.
- The beneficiaries — Mandatory or optional family extension, and breakdown of employer contribution.
5. The employee sent abroad: the contract does not follow him
Reimbursement calculated based on French rates, for care billed elsewhere
A French group health insurance plan provides supplementary reimbursements to the French basic health insurance scheme, based on French standard rates. The seconded employee remains covered by this scheme—articles L. 761-1 and L. 761-2 of the French Social Security Code, European coordination regulations, or bilateral agreements—and the contract covers them, but on that basis. The expatriate is no longer covered: there is no longer a basis for reimbursement, and the group contract becomes ineffective.
Specifically. A ten-day hospitalization in an international hospital costs several tens of thousands of euros; the French contract will reimburse a percentage of a French rate unrelated to it. The remaining balance is not a remainder; it is the bulk of the sum. — and it is settled between the employee and their employer, often before the labor court. This coverage is built outside the domestic system: French Nationals Abroad Fund, first-euro contract, repatriation and supplementary insurance.
Three questions. If one of them stops you in your tracks, the topic concerns you.
Where is the document that established your health insurance plan, and does it correspond to the rates you pay? On what objective criteria is the category you cover differently based? And for each non-member employee, do you have their written exemption on file?
Our position
The subject is not insurance-related, it is probationary.
This is the only type of business contract whose strength depends on documents other than the contract itself. You can have the best guarantee on the market and an indefensible case; you can have an average guarantee and pass an audit without a single issue.
In most of the cases we take over, the contract itself is sound: it's the founding document that's missing, the category that's poorly defined, or the exemptions that were never collected. Bringing it into compliance costs one meeting and one amendment. Correcting it takes three fiscal years.
Are you an employer and have you never had your group health insurance plan reviewed?
The first interview focuses on three points: the relevance of the founding act, the soundness of the objective category, and compliance with the responsible specifications. Forty-five minutes, with no obligation — and if the file is clean, we stop there.
Are you a chartered accountant, lawyer, notary or fellow broker? These cases involve the intersection of labor law, social security, and insurance. We work in partnership, including during audits; the client remains yours.
