Hiring the first employee in France creates a practical question that is easy to underestimate: can a foreign employer simply pay the employee’s private health insurance instead of arranging a French company plan? In most private-sector situations, the answer is no. The statutory French health system reimburses part of medical costs, but it does not replace the employer’s complementary collective health cover, commonly called a “mutuelle”. The company must organise that cover, finance at least the statutory minimum share and give the employee a clear written notice of the applicable rules. A private foreign policy can matter only if it fits a recognised exemption or another applicable coordination rule.

The obligation is not removed because the shareholder is foreign, the board meets outside France, or the business is still small. A French SAS, a French SARL, a branch, and in some circumstances a foreign company with an employee working in France must all analyse the French social-security rules. The administrative route can differ: a French establishment may use ordinary payroll, while a foreign company without a French establishment may use the URSSAF Titre firmes étrangères service. The health-insurance decision itself still has to be documented.

This guide answers the questions a foreign founder normally has before the first payslip: why private reimbursement is not normally a substitute, what the mandatory plan covers, how to set it up, when private cover can support a lawful refusal, how the 2026 “versement santé” payment works, and what must happen when employment ends. It also separates health cover from income protection, tax withholding and the employer’s other registration duties, so that a company does not mistake one French acronym for another.

For the wider company-formation framework, see the firm’s French business law and company formation guidance. This article focuses on the narrower hiring and employee-benefits question that arises once a foreign founder is ready to put the first French payroll in place.

I. Can a foreign employer pay private health insurance instead of a French company mutuelle?

A. Why does a foreign policy not automatically replace the collective plan?

French law distinguishes between statutory health insurance and complementary health insurance. Statutory insurance is administered through the French social-security system and reimburses a regulated part of medical treatment. The employer’s complementary plan pays some or all of the remaining eligible cost under its contract. The two layers are designed to work together. Buying a private international policy for the founder does not, by itself, satisfy the employer’s obligation towards an employee covered by French social-security rules.

The central rule is Article L. 911-7 of the French Social Security Code. Its wording states that “L’employeur assure au minimum la moitié du financement” of the collective complementary health cover. In practical terms, the employer must normally pay at least 50% of the premium. If the monthly premium is €80, the company must normally pay at least €40. The employment contract, a collective agreement or a more favourable company decision can make the employer’s share higher.

Article L. 911-7 also requires a minimum level of cover. The plan must reimburse the employee’s statutory co-payment for covered healthcare, subject to the legal exceptions, the hospital daily charge in the cases provided by law, and specified dental and optical or medical-device costs. The employer should ask the insurer for a compliance summary rather than relying on a sales label such as “international”, “executive” or “premium”. The relevant question is whether the contract supplies the legally required guarantees for the employees who are covered.

The plan must also fit the “responsible contract” rules. Article L. 871-1 of the French Social Security Code sets the legal framework for responsible complementary health contracts, while Article R. 871-2 details guarantee and reimbursement conditions. Those provisions matter not only to the employee’s benefits. They also influence whether the employer’s contribution receives the expected social-security treatment. A plan selected only because it is available in the founder’s home country may fail the French requirements.

There is no “first employee” exemption. A company with one employee still has an employee category, and a mandatory collective plan can apply to that category even when no other employee exists. The employer cannot postpone the decision until the second hire or after the probation period simply because the organisation is small. The effective date must be consistent with the employment relationship and the insurer’s enrolment rules.

Collective does not mean that every person connected with the company must be insured. It means that the plan is defined for an objective category of employees. A foreign shareholder who is not an employee is not automatically included. A president of a French SAS may have a different social-security status from an ordinary employee, and a director who receives no employment salary may be outside the employee plan. Those questions should be separated from the rights of the first person hired under an employment contract.

The employer must use objective categories, not nationality or personal preference. Article R. 242-1-1 of the Social Security Code governs the definition of employee categories for complementary social protection. A plan for “French employees” and a different plan for “foreign employees” would raise an immediate legal problem. Categories can be based on legally recognised classifications, such as the status used by an applicable collective agreement, but they must not be a disguised way to exclude a person from a mandatory benefit.

The applicable French collective agreement is therefore the first substantive check. The company must identify the activity, the applicable collective agreement and its identification number, often called the IDCC number. The agreement may impose a higher contribution, a particular insurer or additional guarantees. The founder’s nationality, the location of the parent company and the language used by the board do not displace an agreement that applies to the French employment relationship.

Health insurance is not the same as “prévoyance”, the separate protection that may cover death, incapacity for work or disability. Some sectors require both. A company may comply with the minimum health plan and still have a separate obligation to arrange income-protection cover. The employment file should identify both products and their legal basis. Combining them in one commercial package is acceptable only if each required guarantee and contribution is clearly documented.

For a foreign founder, the safe conclusion is simple: budget for a French-compliant collective health plan from the first employee’s start date, check the applicable collective agreement, and do not treat a private policy held by the founder or an overseas parent as a substitute. The business can then choose a cost-effective insurer, but it cannot choose whether the legal analysis is needed.

B. What must a foreign founder document before the first payroll?

The legal instrument is as important as the insurance contract. Article L. 911-1 of the Social Security Code provides that collective guarantees can be determined by a collective agreement, a ratified proposal from the employer and employee representatives, or “par une décision unilatérale du chef d’entreprise constatée dans un écrit remis à chaque intéressé”. In English, that last route is a written unilateral employer decision, usually called a DUE, or décision unilatérale de l’employeur.

A new company with one employee will often use a DUE if no collective agreement or employee referendum is available. That choice is not a casual email saying “the company offers health insurance”. The DUE should identify the employer, its registration numbers, the covered employee category, the insurer and policy, the effective date, the guarantees, the employer and employee contribution, the treatment of dependants, the permitted exemptions and the portability rules at the end of employment. It should explain how and when the employee receives the insurer’s documents.

The company should give the DUE and the insurance notice before the plan takes effect, retain evidence of delivery, and obtain the employee’s written response where the employee requests an exemption. The employee’s signature does not turn a non-compliant plan into a compliant one, but the delivery record is important evidence that the company informed the employee. A foreign founder should keep the French original and, if useful, an English explanatory translation. The operative document must remain legally intelligible and consistent with the French insurer’s terms.

The written notice should also state what happens if the employee changes status. A fixed-term employee, part-time employee, employee already covered by another collective plan and employee receiving certain public assistance may have different options. The company should not write a blanket clause saying “waiver is never possible”, because the legal instrument may permit a statutory exemption and the employee may be entitled to request it. Conversely, the company should not accept a vague refusal with no legal ground or supporting evidence.

Next, the founder must identify whether the employer is a French entity or a foreign company employing in France without a French establishment. A French SAS or SARL normally has a SIREN number, the nine-digit company identifier, and a SIRET number, the fourteen-digit establishment identifier. The French business formalities system is operated through the INPI, the National Institute of Industrial Property. The INPI Guichet unique centralises company creation, modification and cessation formalities and feeds the National Register of Enterprises.

A foreign company without a French establishment can still have French employment obligations. The INPI’s authority guidance distinguishes, among other situations, a foreign company with an employee in France from a foreign company with no employee. The social-security registration route should be checked before the first start date. The fact that the contract was signed by a parent company in London, New York or Singapore does not decide where the employee’s social contributions are due.

For an eligible foreign employer without a French establishment, URSSAF, the body that collects French social-security contributions, offers the TFE, or Titre firmes étrangères service. URSSAF explains on its official TFE page that the service is designed for a foreign company established abroad with no French establishment hiring an employee in France. It can simplify declarations and payment of mandatory social contributions. It does not replace the employer’s decision about the complementary health plan.

The TFE route can include the DPAE, meaning déclaration préalable à l’embauche, the prior hiring declaration, and employment-contract information. The company should not confuse the DPAE with health-insurance enrolment. One proves that the hiring has been declared; the other establishes the employee’s complementary cover. The URSSAF foreign-firms guidance also explains that a foreign employer without an establishment can use the TFE or the ordinary DSN route. DSN means déclaration sociale nominative, the recurring social declaration used for payroll data.

Timing matters. URSSAF states that, after obtaining the SIRET needed for the service, the employer should allow the indicated processing period before joining TFE. The employer must also contact the relevant social-protection bodies according to the applicable collective agreement. Pay slips have their own language requirements: the TFE guidance says that pay slips are issued in French, even though certain other documents may be prepared in English, French or German. The founder can manage the business in English while still meeting French payroll formalities.

Tax withholding is another separate workstream. The French PAS, or prélèvement à la source, is income-tax withholding at source. The French tax administration’s employer guidance explains that a foreign employer may need a SIREN or SIRET, a professional account on impots.gouv.fr, a SEPA bank account and the appropriate DSN process. That tax registration does not prove that the employee has been enrolled in a compliant health plan. The founder should maintain a checklist with separate owners for company registration, social payroll, tax withholding and insurance.

A practical DUE file for the first hire should contain at least the following items:

• the applicable collective agreement and the employee category used by the plan;
• the insurer’s contract, guarantee table and responsible-contract confirmation;
• the DUE or other legal instrument, with its effective date;
• evidence that the employee received the DUE, insurer notice and enrolment instructions;
• the employer’s contribution calculation and the payroll setting used for it;
• any written exemption request, supporting certificate and expiry date;
• the DPAE, SIRET, TFE or DSN records relevant to the employer’s structure; and
• the insurer’s confirmation that the employee was enrolled or that a lawful exemption was recorded.

This file is particularly important when the first employee is hired by a foreign parent with no French HR department. The founder may be able to sign the DUE electronically, but the company should confirm that the signer has authority to bind the employer and that the insurer accepts the entity’s legal form. The contract, DUE, payroll data and insurer enrolment should all show the same employer name, registration number and effective date.

For a company that already has a first-employee payroll question, the related DPAE guide for a foreign employer without a French establishment and the article on signing a first French employment contract before receiving the Kbis address adjacent issues. Kbis is the commercial-register extract that evidences a company’s registration. Those questions should be coordinated with the health-plan work, not used as a reason to leave the insurance decision undocumented.

II. Can the first French employee refuse the company health plan?

A. Which exemptions can validate private cover?

The default rule is mandatory enrolment. A first employee cannot simply reply, “I already have private insurance,” and turn the company plan into an optional benefit. A refusal is valid only when a statutory category applies and the employer’s legal instrument permits the relevant exemption where that is required. The employee normally has to make the request at the right time and provide the evidence needed to show that the conditions are met.

The main categories include an employee who is already covered by another collective and mandatory health plan, including in some cases through a spouse; an employee who had individual health cover when the company plan was implemented, until that individual policy expires; certain employees receiving complementary health assistance; and categories of short-term, part-time or apprentice employees where the relevant legal conditions are fulfilled. The details are not interchangeable. A certificate for an individual policy is not the same as proof of cover under another compulsory collective plan.

Article D. 911-2 of the Social Security Code lists several situations in which an employee may request a dispensation. Its evidence rule is explicit: “Dans tous les cas, l’employeur doit être en mesure de produire la demande de dispense des salariés concernés.” The company therefore needs the employee’s request, not merely a note in an HR spreadsheet and not a verbal statement made to the founder.

The legal instrument must be checked as well. Article D. 911-4 deals with situations in which the act establishing the plan can provide exemption categories, subject to the conditions in the Social Security Code. Article R. 242-1-6 also links the social-security treatment of the guarantees to the employee-chosen dispenses listed in the legal act. The DUE should therefore reproduce the options that the company is actually prepared to administer.

Timing is decisive. Article D. 911-5 says that requests “doivent être formulées au moment de l’embauche” in the relevant situation. In other words, an employee cannot necessarily wait until the first payroll has been processed, ignore the plan for several months and then demand that the company reconstruct the history. The employer should create a dated process: deliver the notice, ask the employee to select enrolment or a listed exemption, and review the evidence before the first contribution is sent.

A short fixed-term contract deserves separate attention. Under the applicable rules, some employees on a fixed-term contract or assignment of three months or less, and some employees whose effective working time is no more than 15 hours per week, may request the “versement santé” instead of enrolment in the collective plan. The thresholds are reflected in Article D. 911-7. The employee must have qualifying individual responsible cover, and the employer must follow the specific payment and evidence rules.

The versement santé is not a general cash allowance that every employee can choose. It is an employer payment intended to help finance qualifying individual cover for defined categories. Article L. 911-7-1 sets the statutory mechanism, and the Order of 8 January 2026 fixes the 2026 reference amount at €22.27, or €7.44 for the applicable Alsace-Moselle situation. The amount is not necessarily the employee’s final payment: the legal calculation and coefficients must be applied to the employee’s category and the employer’s normal contribution.

For 2026, the reference calculation can use a coefficient of 105% for an open-ended employee and 125% for a fixed-term or assignment employee in the relevant cases. The company should verify the current payroll rule, the collective agreement and the employee’s proof of individual responsible cover before paying. A foreign founder should not import a monthly allowance formula from another country and call it versement santé. The French payment has a specific legal purpose and must be traceable in payroll.

Other short-contract cases may require the employee to remain enrolled. A fixed-term contract lasting longer than the statutory threshold is not automatically eligible. A part-time employee working more than the relevant limit is not automatically eligible. A person who has a foreign policy that does not meet the responsible-cover conditions is not automatically eligible either. The employer should record the legal ground for each dispensation and set a review date when a certificate expires or the employment status changes.

Individual insurance is another common source of error. The employee may request a dispensation while the individual contract remains in force in the situation authorised by law, but the request should be made at the implementation or hiring stage as applicable. Once the individual policy ends, the employee may need to join the company plan. The employer should not keep an exemption open indefinitely because the original certificate looked satisfactory in the first month.

The same discipline applies to an employee covered through a spouse or another employer. The certificate should identify the insured person, the collective and mandatory nature of the cover, the period of validity and, where relevant, the fact that the first employee is actually included. A family membership card alone may not demonstrate that the French legal condition is met. The employer or broker can provide the correct certificate, but the employer remains responsible for maintaining the employment file.

Finally, the employee’s refusal is not the same as a refusal to work or a rejection of the employment contract. Where the legal conditions are fulfilled, the employer should respect the dispensation and administer the alternative correctly. Where the conditions are not fulfilled, the employer should explain the missing evidence and enrol the employee in the collective plan. A foreign founder should avoid threatening language and instead send a written decision that identifies the rule, the document required and the date by which the employee must respond.

B. What happens if the employer pays the wrong plan or the employee leaves?

A reliable process starts before the employment contract is signed. First, identify the employer, the place where the work is performed, the applicable collective agreement and the likely social-security affiliation. Second, determine whether the company is a French entity or a foreign company without a French establishment. Third, obtain the insurer’s proposal and check the minimum guarantees, contribution split, employee categories, waiting periods, family options and exemption process. Fourth, execute the DUE or other instrument and give it to the employee with the insurer’s notice.

Before the first payroll, reconcile four dates: the employment start date, the effective date in the DUE, the insurer enrolment date and the date used in payroll. If those dates do not match, the company may collect the wrong employee contribution or create an uninsured period. The payroll provider should receive the employer’s contribution rate and the treatment of any employee exemption. For a foreign company using TFE or DSN, the payroll file should still show the complementary health contribution separately from statutory social contributions.

Payroll treatment also affects social-security relief. Article L. 242-1 of the Social Security Code sets conditions under which employer contributions to complementary social protection can be excluded from the social-security contribution base within legal limits. The conditions include a collective and mandatory arrangement, objective employee categories and compliant health guarantees. If a founder creates a bespoke benefit for one person without the right legal structure, the expected exemption from the contribution base may be challenged even if the insurer has issued a policy.

The category rules must be checked against actual payroll. Article R. 242-1-1 prevents the employer from using an arbitrary distinction based on contract characteristics where the law does not permit it. A company cannot describe the plan as collective in its DUE and then quietly reimburse only the founder’s preferred employees. If the business grows from one employee to five, the founder should revisit the category, the collective agreement and the insurer’s enrolment records rather than assuming that the original one-person setup automatically scales.

The courts have treated unequal financing seriously. In Cour de cassation, Social Chamber, 30 April 2014, no. 13-12.769, the court examined different employer financing of complementary health and welfare cover between employee categories. In Cour de cassation, Social Chamber, 13 March 2013, no. 11-20.490, the decision likewise addressed a difference in employer financing of a collective health plan. These decisions do not prohibit every differentiated category, but they show why the category, its legal basis and the employer contribution must be documented before the first employee is hired.

The company should also plan for the end of employment on day one. Under Article L. 911-8 of the Social Security Code, an employee may retain collective health and certain welfare cover after employment ends when the legal portability conditions are met, generally for a maximum period linked to the period of unemployment-benefit entitlement and capped at twelve months. The employer must give the required information and notify the insurer. The employment certificate and termination documents should not omit the portability information.

The portability rule is not limited to a simple resignation-versus-dismissal checklist. In Cour de cassation, Second Civil Chamber, 5 November 2020, no. 19-17.164, the court treated Article L. 911-8 as public-order law. The decision describes the provisions as “Ces dispositions, qui revêtent un caractère d’ordre public”. It rejected an approach that would make portability disappear merely because the employer entered liquidation, subject to the statutory conditions. A foreign parent winding down its French activity must therefore plan the insurer and employee notices rather than assuming that closure ends every benefit obligation.

Evidence also matters at termination. Cour de cassation, Social Chamber, 27 January 2021, no. 19-17.457, concerned arguments about the absence of an effective complementary-health certificate and the handling of portability information. The lesson for a small employer is practical: retain the enrolment certificate, the DUE, employee notices, contribution records and termination communication in one file. If the company cannot show what it arranged and when, a later disagreement becomes a question of proof as well as a question of law.

The employer should not cancel a collective plan without checking how the change affects existing employees. In Cour de cassation, Social Chamber, 20 November 2013, no. 12-27.194, the court considered the consequences of removing collective cover in a context governed by collective rules. A new foreign founder who acquires a French company should audit the existing DUE, collective agreement and insurance contract before replacing them. Switching brokers is not the same as changing the legal instrument, and cancelling the policy before the replacement is effective can create a gap.

The following examples illustrate the distinction between the common cases:

Situation	Likely first action	Frequent error
French SAS hires its first employee on an open-ended contract	Check the collective agreement, adopt a DUE if appropriate, enrol the employee and pay at least the required employer share.	Waiting until the company has two employees or until the probation period ends.
Foreign parent has no French establishment and employs a person in France	Confirm the URSSAF registration route, use TFE or DSN as appropriate, and separately implement the collective health plan.	Assuming the TFE replaces the insurer enrolment or the DUE.
Employee is on a qualifying short fixed-term contract	Check the duration, working time, responsible individual cover and the versement santé conditions before accepting a dispensation.	Paying a cash allowance without a written request or valid certificate.
Employee is covered by a spouse’s compulsory collective plan	Obtain the correct certificate, record the dated request and set a review date.	Keeping the employee outside the company plan after the outside cover expires.
Employment ends after several months	Check portability, notify the insurer and give the employee the required information with the termination documents.	Deleting the employee from the insurer on the last day without assessing Article L. 911-8.

For a foreign founder, the best operational sequence is therefore: determine the legal employer; identify the collective agreement; choose a compliant insurer; write the DUE or apply the appropriate collective instrument; give the notice; collect any lawful exemption request; configure payroll; check the first payslip; and archive the evidence. The founder should then calendar the end of each certificate, the employee’s status changes and the portability steps. This process is more reliable than asking a broker to “sort out the mutuelle” after the first payroll has already been filed.

Three red flags justify an immediate review. The first is a company paying the employee’s private foreign insurance instead of enrolling the employee in a French-compliant collective arrangement. The second is a DUE that says the plan is mandatory but contains no exemption procedure or evidence trail. The third is a payroll file that shows a health contribution while the insurer has no enrolment record. Each red flag can be corrected, but the company should document the correction date and avoid presenting a retrospective document as if it had been issued before the employee started.

The legal analysis can also change when the employee works from home, moves between France and another country, becomes a director, changes from a fixed-term contract to an open-ended contract or joins a new collective agreement. Social-security affiliation, employment law, tax residence and health-plan administration are connected but not identical. A foreign founder should ask for a written status analysis when the work pattern is cross-border, rather than treating the employee’s passport or the parent company’s country as the decisive fact.

Conclusion

A foreign founder hiring the first employee in France should assume that reimbursing a private foreign policy is not a substitute for a compliant collective complementary health plan unless a specific legal exemption applies. The company must normally finance at least half of the premium, use an appropriate legal instrument, apply objective employee categories, keep written evidence and coordinate the plan with French payroll. The TFE, DPAE, DSN, INPI registration and tax-withholding steps may simplify administration, but none of them replaces the health-plan decision.

The employee may refuse enrolment only through a recognised dispensation route, with a timely request and the supporting evidence required by the French Social Security Code. For short contracts and limited working time, the 2026 versement santé rules may offer an alternative, but the amount and eligibility conditions must be calculated rather than guessed. At termination, portability and the evidence of notices must be handled before the file is closed.
