For a foreign founder, hiring the first employee of a French company can look straightforward: sign an employment contract, register the employee with the French social-contribution system, run payroll, and start the work. That sequence is often wrong when the employee will perform the work from another country. The decisive fact is usually not the nationality of the company or the currency in which the salary is paid. It is the country in which the employee habitually performs the work, subject to the special rules for temporary postings and work carried out in several countries.

The distinction matters immediately. A French company that recruits a person who will work permanently from Belgium, Portugal, the United Kingdom or the United States is not automatically operating a French payroll for that person. It may need a local registration, local social contributions, local income-tax withholding, a compliant local employment arrangement and an assessment of whether the employee creates a taxable permanent establishment. A French employment contract cannot, by itself, choose French social security or remove mandatory rules in the employee’s country.

This article gives a decision framework for a foreign-owned French SAS or SARL, explains the difference between a genuinely foreign hire and a temporary French posting, and sets out the documents to prepare before the start date. It does not replace a country-specific review: bilateral treaties, local payroll rules, immigration requirements and permanent-establishment tests differ from one country to another.

I. Can a French company hire an employee who works remotely from another country?

A. What changes when the employee is hired abroad rather than sent from France?

The first question is factual: where will the employee actually work, and for how long? A foreign-owned French company may have its registered office in Paris, a French SIREN number (the unique national identification number of a company), a French bank account and a Kbis (the official extract proving registration of a commercial company), while its employee works every day from a home office in another country. Those French corporate markers do not determine the employee’s social-security affiliation.

The practical starting point is the rule published by the Centre of European and International Liaisons for Social Security, commonly called CLEISS. Its employer guidance states: “If you hire an employee abroad to make him work in this country, he will obligatorily come under the social security regime of this country. The social contributions will be paid in this country.” The words are direct, but the classification still requires care. A person already employed in France and temporarily sent abroad may fall under a different regime. A person recruited to work permanently abroad normally does not.

For an EU, EEA or Swiss situation, Article 11(3)(a) of Regulation (EC) No 883/2004 applies the legislation of the state where the employed activity is pursued, subject to the special rules in Articles 12 to 16. The regulation also states that people covered by it are subject to the legislation of “a single Member State only.” The official text is available in the consolidated Regulation (EC) No 883/2004.

That produces three different scenarios for a foreign founder:

1. A permanent foreign hire: the employee is recruited by the French company but habitually works in the other country. The employer normally enters that country’s payroll and social-security system, or uses a lawful local employment solution. The employee’s country may also require registration for payroll tax, labour-law notices, occupational insurance and pension contributions.

2. A temporary posting from France: the employee already works for the French company, remains under its direction and is sent abroad for a limited assignment. An applicable European or bilateral instrument may preserve French social security. In the EU, an A1 document is the portable certificate used to show which social-security legislation applies. The company must obtain it before the assignment where the competent institution requires that sequence; it is not a general permission to employ someone abroad indefinitely.

3. A regular multi-state worker: the employee works habitually in France and at least one other state. Article 13 of Regulation No 883/2004 can allocate the whole social-security relationship to the employee’s state of residence when a substantial part of the activity is performed there, or to the state of the employer’s registered office when the worker does not perform a substantial part in the residence state. The percentages, evidence and administrative route must be tested against the actual work pattern rather than the wording of the contract.

The French Social Security Code confirms the same architecture. Article L. 111-2-2 of the French Social Security Code covers people who work in France for an employer “having or not having an establishment in France” and people working abroad who remain subject to French legislation under European regulations or international conventions. In the official French wording, the first category begins: “Une activité pour le compte d’un ou de plusieurs employeurs, ayant ou non un établissement en France.” This is not a licence to choose French affiliation; it is a statutory expression of the applicable-legislation rules.

The company should therefore write a one-page facts memo before selecting a payroll route. It should record the employee’s residence, expected work location, percentage of work in each country, travel to France, other employers, start date, expected duration, authority to sign contracts, access to customers and whether the person will work from a fixed home office or changing locations. The memo is evidence for the social-security analysis and later tax review. A vague “remote from Europe” clause is not enough.

The employment relationship itself also has a conflict-of-laws dimension. Article 8 of Regulation (EC) No 593/2008, known as Rome I, allows the parties to choose a governing law but prevents that choice from depriving the employee of non-derogable protections that would otherwise apply. Without a choice, the contract is generally connected to the country where, or from which, the employee habitually works. The English text states: “The country where the work is habitually carried out shall not be deemed to have changed if he is temporarily employed in another country.” A contract that says “French law applies” does not erase mandatory host-country rules.

French case law follows the same factual approach. In Cour de cassation, Social Chamber, 3 March 2015, no. 13-24.194, the Court recalled that, absent a valid contrary analysis, the relevant connection is the country where the employee habitually performs the work. In Cour de cassation, Social Chamber, 13 October 2016, no. 15-16.872, the Court rejected a French-law approach where the employee had been directly engaged in India and worked exclusively in Delhi. The lesson for a founder is operational: payroll follows the documented reality of the work, not the French address printed on the company’s Kbis.

B. Which social-security country applies: France, the employee’s country or an A1 exception?

The cleanest way to decide is to classify the start date before any salary is paid.

If the employee has never worked in France and will work full-time from another country, treat the case as a foreign-country employment project. Ask the foreign authority or local payroll adviser whether the French company can register directly as a non-resident employer. Some countries permit direct registration. Others require a local establishment, an appointed representative, a payroll agent or an employer-of-record arrangement. An employer of record, or EOR, is a local entity that becomes the formal employer and supplies the employee to the French business under a separate commercial agreement. It is not a substitute for reviewing the underlying work, tax and corporate risks.

If the employee is moving temporarily from France to another country, start with the posting rules. Article L. 761-1 of the French Social Security Code concerns employees temporarily sent abroad by their employer who remain subject to French social-security legislation under international agreements or European regulations. The French text uses the words “Les travailleurs détachés temporairement à l’étranger par leur employeur.” The employee must actually fit that model: an existing employment relationship, a temporary assignment and an applicable instrument. A new hire whose only workplace is abroad is not converted into a posted worker by inserting “temporary assignment” into the contract.

For assignments not covered by an international agreement, Article L. 761-2 of the French Social Security Code provides a limited route where the employer undertakes to pay all contributions due. The provision states that the employee is subject to French legislation on the condition that the employer undertakes “s’acquitter de l’intégralité des cotisations dues.” That route has duration limits and does not remove the host country’s own employment, tax, immigration or registration requirements. It must be analysed with the country-specific bilateral position.

For two-state telework within the EU, EEA or Switzerland, the cross-border telework framework may help, but it is narrower than many founders assume. CLEISS explains that the framework in force since 1 July 2023 can simplify a request to remain under the social-security legislation of the employer’s state when the residence state and employer state have both signed the framework, the employee works in two states, telework in the residence state is less than 50% of total working time, the employee has no other non-telework activity in the residence state and the other conditions are met. The CLEISS cross-border telework guidance says: “The telework must represent less than 50 % of his total working time.” It also identifies the competent institution and the A1 process.

The framework is not a universal remote-work passport. CLEISS expressly gives an example in which an employee works exclusively by telework from the residence state and concludes that the framework does not apply because telework represents the whole activity. In that situation, the ordinary rule can point to the residence or work state. The founder should also check whether the United Kingdom is covered by the same route for the specific facts: post-Brexit coordination is treaty-based and should not be assumed to be identical to an EU posting.

For a permanent full-time remote employee abroad, the ordinary outcome is therefore local affiliation. The French company may still have French obligations for the French workforce, its directors or its own French payroll, but it should not put the foreign employee on a French payroll merely to simplify administration. The French employer’s payroll provider should document the reason for the foreign treatment and retain the foreign registration, certificate or written advice.

The employee’s work pattern can change. A monthly trip to Paris, a client-facing role, a second employer or a move to a new residence can alter the analysis. The company should set a review trigger for each change. It should not wait for an audit or a social-security dispute to reconstruct the work calendar.

II. How should a foreign founder document payroll, tax and permanent-establishment risk?

A. What must the French company put in the contract and payroll file?

The employment contract should identify the real employer, the normal work country, the approved work address or addresses, the expected presence in France, the applicable working-time zone, the reporting line and the process for changing location. It should state that no work from a new country is permitted until the company has checked local employment, payroll, social-security, tax, immigration, data-protection and insurance requirements. That is a risk-control clause, not an attempt to contract out of mandatory law.

The company should also state how equipment, cybersecurity, confidential information, intellectual property, expenses, business travel, working time, rest periods and emergency contact will be handled. A foreign founder may be tempted to leave the location open because the employee is “fully remote”. That can create an unplanned tax presence, an uninsured workplace or an employment-law conflict. A defined primary country, with a written approval process for temporary travel, is safer.

If French employment law applies to all or part of the relationship, Article L. 1221-3 of the French Labour Code requires a written employment contract to be drafted in French and allows a foreign employee to request a translation in the employee’s language. The official text states: “Le contrat de travail établi par écrit est rédigé en français.” It also provides that, if there is a discrepancy, the version in the foreign employee’s language can be invoked against the employee. A founder who wants an English-facing business should prepare a bilingual document with a deliberate priority clause and country-specific review, rather than use an informal English template.

The contract should not confuse telework under French law with cross-border employment. Article L. 1222-9 of the French Labour Code defines telework as work that could have been performed at the employer’s premises but is performed outside them voluntarily using information and communication technologies. It also requires a collective agreement, an employer charter or a formal agreement by another means where no charter or agreement exists. The article gives the teleworker the same rights as a workplace employee and creates a presumption for an accident at the place of telework. Those French requirements may govern the French side of the relationship, but they do not answer which foreign social-security or labour rules apply at the employee’s home.

The Court of cassation’s recent decision in Social Chamber, 19 March 2025, no. 22-17.315 is a useful reminder that the place used for work has legal consequences. The Court wrote: “L’occupation du domicile du salarié à des fins professionnelles constitue une immixtion dans sa vie privée.” In English, using the employee’s home for work can create a compensable constraint when the employer has not provided a professional location or the parties agreed to telework. A foreign home office should therefore be addressed in the contract, expense policy, insurance file and health-and-safety assessment. The founder should not rely only on a “no office provided” assumption.

Before the first start date, the payroll file should contain at least:

• a country-of-work and residence memo signed by the company and employee;
• the employment contract and any bilingual version;
• the foreign social-security registration, employer number or written confirmation of the local route;
• the local payroll-tax registration and payment calendar, where required;
• an A1 or equivalent certificate if the employee is temporarily covered by another state’s legislation;
• the work-location and travel policy, including the maximum days permitted in France;
• insurance confirmation for occupational accidents, employer liability and equipment;
• the analysis of whether a French Déclaration préalable à l’embauche (DPAE, the pre-hire declaration) is required or whether the foreign system applies; and
• a written tax and permanent-establishment assessment for the employee’s country.

French payroll formalities should be used when French legislation actually applies. Article L. 1221-10 of the French Labour Code states that hiring cannot occur until the employer has made a nominative declaration to the designated social-protection bodies and that the declaration is made in each workplace where employees work. Its wording is: “L’embauche d’un salarié ne peut intervenir qu’après déclaration nominative accomplie par l’employeur auprès des organismes de protection sociale désignés à cet effet.” If the employee works abroad under the foreign system, the company must identify the corresponding local declaration instead of treating a French DPAE as a universal solution. The SIRET, or establishment identification number, and the Kbis may prove the French company’s existence, but neither proves that the foreign payroll formalities are complete.

The French company should also decide whether any French monthly payroll return is appropriate. The DSN, or Déclaration sociale nominative, is France’s electronic social payroll return. It is not a substitute for a foreign employer return. If French affiliation is maintained for a posted or multi-state employee, the payroll provider should map the correct French declarations, contribution bases and A1 evidence. If foreign affiliation applies, the company should prevent accidental French withholding or duplicate contributions unless a specialist has confirmed that a particular French item remains due.

Tax is a separate analysis. A non-resident employee’s salary is not automatically taxed in France merely because the employer is a French company. The applicable treaty, the place where duties are physically performed, the employee’s tax residence, the employer’s economic cost and any special remuneration rule must be reviewed. Article 182 A of the French General Tax Code (CGI, Code général des impôts) addresses withholding on French-source salaries paid to people who are not tax resident in France, subject to its exceptions. That does not decide the source of every cross-border salary; the treaty and factual source rules still matter.

Conversely, Article 81 A of the CGI is not a shortcut for a person hired abroad. Its text concerns persons tax resident in France who are sent abroad by an employer established in France or certain other qualifying states. Article 81 A of the CGI is therefore a poor fit for a foreign resident hired from the start to work in that foreign country; that person should not be presented as an Article 81 A expatriate merely because the salary is paid from France.

The French company’s own corporate income tax position also needs a separate line in the file. Article 209 of the CGI generally measures French corporate-taxable profits by reference to profits of businesses operated in France and income attributed to France by a tax treaty. Article 209 of the CGI refers to “les bénéfices réalisés dans les entreprises exploitées en France.” That rule does not mean that every foreign employee creates a second company or a taxable branch, but it does require an analysis of what the employee does abroad and whether the host country considers the French company to have a permanent establishment.

B. When should the founder use local registration, an employer of record or a French posting?

The choice should follow the legal classification, the expected duration and the commercial role of the employee. It should not be made solely on the cheapest payroll quote.

Direct local registration can work when the employee is genuinely part of the French company, the country allows a foreign employer to register, the company can meet local employer duties and the employee’s role does not require a local entity for licensing or contracting. The French company then needs a local compliance calendar: employment registration, payroll, social contributions, income-tax withholding, pension and health schemes, occupational accident cover, leave, local reporting and termination procedure. The company should identify who will receive official notices in the country and who can respond in the local language.

An EOR can be useful for a short market test, a first hire before the French company has local registration capacity, or a country where direct employment is administratively disproportionate. The commercial agreement should describe the employee’s day-to-day direction, invention ownership, confidentiality, data access, expenses, termination instruction, indemnity allocation and audit rights. The founder should check that the EOR is not merely invoicing as a contractor while the French company exercises all employer powers. Misclassification can produce back contributions, penalties, employee claims and joint-liability arguments.

A French posting is appropriate where the person already has a French employment relationship and the foreign work is temporary and documented. The company should define the assignment, apply for the relevant A1 or certificate of coverage, review host-country notifications, maintain a travel record and set a return date or review date. A posting is especially fragile when the employee is hired on the first day for an indefinite home-country role. In that case, the facts point to a foreign hire, not a French employee temporarily away.

The social-security file should also reflect the single-legislation principle. In European Union case C-356/15, Commission v Belgium, the Court of Justice stressed the purpose of the coordination rules: the persons concerned should be subject to the social-security scheme of only one Member State. In European Union case C-527/16, Alpenrind, the Court explained that the general rule connects the worker to the state where the activity is pursued and that the special posting rule must be interpreted strictly. These decisions are not a replacement for the country authority’s determination, but they show why double voluntary registration is not a safe compromise.

French case law also warns against using administrative labels as a substitute for facts. In Cour de cassation, Social Chamber, 18 November 2020, no. 19-17.788, the decision records that an employee’s administrative and tax address in France, and French payslips, were not enough to establish France as the habitual place of work where the work was performed abroad. The decision states that the fact that the worker was “resté administrativement et fiscalement domicilié en France” had no connection with determining the habitual workplace. In Cour de cassation, Social Chamber, 25 January 2012, no. 11-11.374, the Court examined the group’s direction, contract language, pay currency, residence and return arrangements to determine the parties’ implied choice and the relationship’s closest connection. The file should therefore tell a coherent story across the contract, payroll, travel, tax returns and management records.

Permanent-establishment risk requires a separate corporate-tax memo. A permanent establishment, or PE, is generally a taxable business presence in another country under local law and the applicable tax treaty. An employee with no authority to conclude contracts, no customer-facing role and no fixed business premises may present a lower risk than a sales employee who negotiates and habitually binds the French company. The result depends on the treaty wording, the employee’s authority, the business model, the location of management, local premises and the substance of the activity. The memo should answer at least these questions:

• Does the employee habitually negotiate or conclude contracts for the French company?
• Does the employee maintain a place that is effectively available to the company, rather than merely using a private home incidentally?
• Does the employee manage local customers, stock, delivery, regulated activity or local suppliers?
• Does the employee’s work show that the French company is conducting a material part of its business from that country?
• Does the country impose employer, VAT, corporate-income-tax or business-registration obligations even without a treaty PE?

The employee’s home should not be described as a “French office” unless the company is prepared to defend that description. At the same time, a contractual disclaimer saying that the employee has no authority is weak if internal emails, customer negotiations or signature systems show the opposite. The founder should align the delegation matrix, email signature, CRM rights, contract-approval workflow and travel policy with the tax memo.

The remote employee may also handle personal data, trade secrets and regulated information. The company should determine whether data leaves the European Economic Area, whether a transfer mechanism is required, where devices are encrypted, who can access customer files and whether the local country has employee-monitoring restrictions. A foreign founder should not send the full French payroll or customer database to a home device without a documented security policy. These issues are separate from social contributions but often appear in the same inspection or dispute.

The final pre-start checklist should produce a clear answer, not a folder full of contradictory assumptions:

1. Describe the employee’s normal country of residence and work.
2. Classify the relationship as a permanent foreign hire, a temporary posting or habitual work in multiple states.
3. Identify the single social-security legislation that should apply and obtain the A1 or equivalent document where relevant.
4. Confirm the foreign employer registration, payroll, withholding, insurance and reporting route.
5. Check the employment-law choice and mandatory host-country protections under Rome I or the applicable bilateral rules.
6. Draft a contract and location policy that match the actual duties and travel pattern.
7. Review permanent-establishment, corporate-tax, VAT, licensing and local business-registration exposure.
8. Set an internal review date and a mandatory approval process before the employee changes country.

This sequence is particularly important for the first employee because there is no established HR or payroll history to reveal the error. The first payslip, first customer negotiation and first trip can all become evidence. A founder who decides the country and legal route before signing the contract can still preserve the flexibility of remote work without pretending that a French company has only French obligations.

Conclusion

A French company can hire an employee who works remotely from abroad, but the arrangement is not automatically a French payroll arrangement. A permanent foreign hire normally enters the social-security and payroll system of the country where the work is habitually performed. A temporary posting or a compliant multi-state work pattern may justify continued French affiliation, but only after the applicable European or bilateral rules have been checked and the required certificate or institutional decision has been obtained.

For a foreign founder, the safest sequence is to map the facts, choose the applicable social-security legislation, validate the country’s employer-registration route, draft a location-specific contract, and assess tax and permanent-establishment exposure before the first start date. The French company’s Kbis, SIREN, French bank account and French-law clause are useful corporate facts; they are not substitutes for the employee’s actual work-country analysis.
