Hiring a first employee in France from a foreign headquarters creates a payroll obligation that is easy to misclassify. The question is not merely whether the employee can be paid from a foreign bank account. The company must identify the employee’s place of work, the income-tax rules that apply to the salary, the French social-security route, and the reporting channel through which the withholding is declared and paid. Only then can it decide whether the payroll should run through the Déclaration sociale nominative (DSN, the French nominative social declaration) or through PASRAU, the return used for withholding on income other than income reported through the ordinary DSN process.

This article addresses a foreign company hiring a person who works in France, whether the employer has a French subsidiary, a branch, or no French establishment. It explains the difference between the French prélèvement à la source (PAS, pay-as-you-earn income-tax withholding), the DSN, and PASRAU. It also separates resident-employee PAS from the distinct withholding rules for French-source salary paid to a person who is not tax-resident in France. The employee’s immigration status and a founder’s personal move to France require separate advice; a property purchase is outside this article. The practical objective is simple: make the first French payslip, declaration, and payment traceable before the first salary is released.

I. When must a foreign employer collect French income tax on a first employee?

A. Start with the employee, the employer, and the place of work

A foreign parent should not begin with the name of a payroll provider. It should begin with a written fact pattern. Identify who signed the employment contract, who directs the work, where the employee physically works, which entity bears the salary cost, which entity is shown on the payslip, and which entity has accepted the social-security and tax reporting obligations. A French subsidiary, a registered branch, and a foreign company with no French establishment can produce different administrative routes even when the employee performs the same job.

The first geographic question is where the work is performed. An employee who works habitually from France is not transformed into an overseas employee merely because the employment contract was signed abroad or the salary is wired from an account outside France. Conversely, an employee who works entirely outside France should not be put into a French payroll without checking the applicable international tax treaty and social-security rules. Travel days, remote work, secondments, and a change of employing entity can alter the analysis. Keep a dated work-location record rather than relying on the employee’s residential address alone.

The second question is the employee’s tax residence and the source of the salary. For a person whose salary is taxable in France under the rules applicable to employment income, the ordinary PAS mechanism is normally the relevant starting point. Article 204 A of the French General Tax Code states that taxable salary income “donnent lieu … à un prélèvement”: in other words, the taxable income is subject to a levy. The employer’s task is to collect the amount indicated by the administration and to report it through the correct channel; it is not to calculate the employee’s final annual income tax from scratch.

A different question arises when the employee is not tax-resident in France and receives French-source salary taxable in France. The non-resident withholding mechanism under Article 182 A of the General Tax Code should then be examined separately from resident-employee PAS. The current French General Tax Code section on Articles 182 A to 200 C is the official starting point for that distinction. Do not label every French payroll deduction “PAS”: the legal basis, declaration, rate tables, and payment timetable may differ.

Social security is a separate classification exercise. Income tax residence does not by itself determine whether French social contributions are due. A worker employed in France may fall within French social-security legislation, subject to European coordination rules, a bilateral agreement, or a valid certificate covering a temporary assignment. An A1 certificate, where applicable, concerns social-security legislation; it is not a general income-tax exemption. A private health-insurance policy is not a substitute for a legal decision on compulsory social coverage.

Two official decisions illustrate why the written classification matters. In Cour de cassation, Second Civil Chamber, 13 October 2022, no. 21-13.252, the Court held, in a dispute about employees working abroad, that the employees were not subject to French social-security legislation when the employer had not undertaken to pay the full contributions required for the relevant French affiliation. The decision uses the phrase “ce dont il résultait que ces derniers n’étaient pas soumis à la législation française de sécurité sociale”. That case concerned expatriation and older facts, not a standard France-based first hire, but it confirms that social-security coverage cannot be inferred from labels alone.

More recently, Cour de cassation, Social Chamber, 8 October 2025, no. 24-17.726, was decided with “cassation partielle” after a dispute involving a foreign social-security explanation, missing affiliation, missing payslips, and alleged non-compliance with employment formalities. The Court required the lower court to examine the actual arguments and the cumulative evidence rather than treating an asserted foreign arrangement as an answer by itself. The decision is not a ruling on every foreign employer’s PAS liability. It is a useful litigation warning: a cross-border payroll file must prove what happened, not merely state that another country was involved.

Before selecting the tax return, write the following one-page matrix:

Question	Evidence to retain	Why it matters
Where is the work actually performed?	Contract, office or remote-work policy, travel calendar	Supports the source and territorial analysis.
Who is the legal employer?	Signed contract, board approval, intercompany agreement	Identifies the withholding and social-reporting debtor.
Is the employee tax-resident in France?	Employee declaration and tax advice, without requesting unnecessary private data	Helps distinguish ordinary PAS from non-resident withholding.
Are French social contributions due?	Affiliation decision, applicable certificate or agreement, URSSAF correspondence	Usually drives the DSN/PASRAU route.
Where is the salary accounted for and paid?	Payroll ledger, bank instructions, intercompany recharge	Prevents the payment country from being confused with the work country.

If the facts change after the first hire, re-run the matrix. A transfer to a French subsidiary, a long-term assignment outside France, a director appointment, or a change from employee to contractor can change the answer. The first payroll should be treated as a compliance decision, not as a software setting.

B. Complete the French registration and payment setup before the first payslip

A foreign company needs a usable identity in the French administrative systems. A SIREN is the nine-digit identifier of the legal entity; a SIRET adds the five-digit establishment identifier. A Kbis is the official extract evidencing the registration of a commercial company, historically issued through the greffe, the registry office of the commercial court. A Kbis is not itself a tax-withholding authorisation, and the absence of a French Kbis does not automatically remove a foreign employer’s reporting obligations.

For a French subsidiary or branch, the company generally obtains its identifiers through the formalities process. The INPI explanation of the Guichet unique states that a creation filing is sent to the French National Institute of Industrial Property’s one-stop system, then to the competent bodies, with a SIREN pre-attributed by Insee and a definitive identifier after validation. For a foreign employer without a French establishment, the tax administration may require a registration route that produces a SIRET suitable for the professional tax account. The company should retain the registration notice, the identifier, the legal name exactly as registered, and every change notification.

Next create or activate the professional account on impots.gouv.fr. The official French tax administration guidance on PAS procedures identifies the need for a SIREN or SIRET, a professional account, and a bank account with the required SEPA mandate for payment. SEPA is the Single Euro Payments Area. A bank account outside France may be able to make a payment, but it should not be assumed to satisfy the administration’s registration and mandate requirements. Test the mandate, access rights, and two-factor authentication before payroll day.

For a foreign company without a permanent establishment in France, identify the competent tax service early. The tax administration’s guidance explains that a foreign company liable for PAS and not already known to the administration must register to obtain a SIRET, create the professional account, and declare and remit through the designated online process. The operational contact can differ from the local service that would handle a French subsidiary. Put the tax-service reference, the registration date, and the person authorised to act in the compliance file.

Social-security registration must be coordinated rather than postponed. Article L. 243-1-2 of the Social Security Code provides that an employer whose business has no establishment in France fulfils its obligations through a single collection body, an “organisme de recouvrement unique”. The article also contemplates electronic declarations and electronic delivery of documents. Read the current Article L. 243-1-2 of the Social Security Code with the employer’s actual affiliation facts. The Service Firmes Étrangères, the URSSAF service for foreign firms, can be part of that route; the name of the service should be documented, not guessed from a payroll vendor’s generic checklist.

The pre-hire declaration is a separate step. Article L. 1221-10 of the Labour Code states: “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.” This is the Déclaration préalable à l’embauche (DPAE, the prior hiring declaration). A French company, a foreign employer using the relevant French collection route, and an intermediary payroll arrangement must each identify who is legally responsible for filing it. A contract signature, a tax-account opening, or a payroll-provider engagement does not prove that the DPAE was filed.

Article L. 1221-11 of the Labour Code adds a specific consequence for non-compliance with the DPAE obligation: the penalty is equal to three hundred times the hourly rate of the guaranteed minimum referred to by the article. The official Article L. 1221-11 page should be checked for the version applicable to the facts. Retain the filing acknowledgement, the employee’s identifier, the filing timestamp, and any correction acknowledgement.

Use a pre-first-payroll checklist with named owners:

1. Confirm the legal employer and the physical work location.
2. Record the tax classification and the reason ordinary PAS or another withholding mechanism applies.
3. Obtain the SIREN or SIRET required for the selected route and reconcile it with the legal name.
4. Open the professional tax account and assign a backup administrator.
5. Register the bank account and validate the SEPA payment mandate.
6. Complete social-security affiliation or document the applicable international certificate.
7. File the DPAE before the employee starts work.
8. Select a payroll process capable of producing the payslip and the required electronic declaration.
9. Test rate retrieval, error messages, payment authorisation, and evidence export.
10. Set a calendar alert for the first declaration, correction window, payment, and document archive.

If one of these items is missing, the correct response is to identify the missing administrative decision. It is not to issue a payslip under the parent company’s home-country format and hope that a later French filing will cure the gap.

II. How should the employer choose PAS, DSN or PASRAU and control the first payment?

A. Choose the reporting channel and calculate the withholding from the correct base

The DSN is the monthly French social declaration that carries employee, contract, remuneration, and contribution information to the relevant bodies. Article L. 133-5-3 of the Social Security Code requires an employer to send a declaration establishing, for each employee, the place of activity, employment and contract characteristics, remuneration, contributions, and working time. The official Article L. 133-5-3 page also provides for electronic transmission and correction of inaccurate or incomplete data. The DSN is therefore more than a tax form: it is a payroll data channel with social and tax consequences.

PASRAU means “prélèvement à la source pour les revenus autres”, the withholding-at-source return for income not reported through the ordinary DSN route. The practical decision is driven primarily by the social-reporting position, not by the fact that the employer is incorporated abroad. The following table is a decision aid, not a replacement for the employer’s written classification.

Situation to verify	Likely operational channel	Control point
French subsidiary or branch pays French social contributions through the ordinary employer process	DSN, with PAS integrated into the payroll declaration	Confirm the social account, declaration deadline, and payment mandate.
Foreign employer with no French establishment but French social contributions are due and collected through the foreign-firm employer route	Use the route confirmed by the collection body; a DSN-based process may apply	Obtain written confirmation of the declaration format and identifier.
Foreign employer’s employee is taxable in France but the collector is not making French social-contribution declarations	PASRAU may be the relevant withholding return	Confirm the collector status and the competent tax service before the first return.
Salary is French-source but the employee is not tax-resident in France	Examine non-resident withholding rules, including Articles 182 A and 1671 A	Do not force a resident PAS workflow onto a non-resident case.

The official Service-Public explanation of employer PAS obligations describes the ordinary model: the employer applies the tax rate supplied by the tax administration, withholds monthly from the taxable salary, and remits the amount through the relevant declaration. It also identifies PASRAU as the route that can apply to certain foreign employers whose employees reside in France and who are not subject to the ordinary DSN process. Because the fact pattern matters, keep the administration’s response or the collection-body confirmation in the file.

The rate is not selected by the foreign parent. The French tax administration determines the rate for the employee and transmits it through the reporting system. The employer should apply the rate returned for the payroll period and protect the confidentiality of the employee’s wider tax information. If no individualised rate is available, the default or neutral rate may apply under the rules described by the administration. The employer does not use a neutral rate as a permanent substitute for fixing a failed registration or a missing declaration.

The employer also has to respect the period for applying a newly transmitted rate. Official government guidance explains that the employer has sixty days to apply a rate made available by the administration. That period is an operational control, not permission to ignore an old rate indefinitely. A payroll file should show the date the rate was received, the period to which it was applied, the date of any correction, and the reason if the payroll system could not use it.

The taxable base must be distinguished from gross salary and from the amount actually paid to the employee. Article 204 F of the General Tax Code defines the base for the withholding under Article 204 A by reference to the net amount taxable for income tax, before the statutory adjustments identified by that article. The current Article 204 F page should be read with the current payroll rules. On the payslip, the rate and amount must be visible even though the employer does not disclose the employee’s full tax return.

Article 204 E adds that the levy is calculated by applying a rate to the income determined under Articles 204 F and 204 G. The official Article 204 E page is useful when payroll includes taxable benefits, variable pay, or an adjustment. Avoid hard-coding a headline rate into a payroll spreadsheet. The rate may be personalised, neutral, individualised within a household, or updated during the year.

Consider this purely illustrative control calculation. Suppose a payroll engine records gross monthly pay of €6,000, employee social deductions of €1,300, and a deductible component of €100, producing an illustrative net taxable base of €4,800. If the administration has supplied a 15% rate, the illustrative PAS would be €720. The employee’s net pay would then be calculated by the payroll engine after the applicable employee deductions and the €720 withholding. The figures are not a legal rate, a quotation, or a substitute for the employee’s payroll data. The point is to reconcile four separate fields: gross pay, net taxable pay, supplied rate, and amount withheld.

Timing is another frequent source of error. For the ordinary DSN, the filing deadline depends on the employer’s workforce and payment practice; government guidance describes the fifteenth of the following month for employers with fewer than fifty employees and, for larger employers, the fifth or fifteenth depending on the pay timing. That schedule should not automatically be copied to every PASRAU case. The declaration acknowledgement, the payment due date, the actual bank debit, and the payroll period should be reconciled in one calendar. A small employer’s possible quarterly payment option, where available, must be formally selected and configured rather than assumed.

For non-resident withholding, Article 1671 A is a useful warning against mixing systems. In its current version, the provision says: “Les retenues prévues aux articles 182 A, 182 A bis et 182 B sont opérées par le débiteur des sommes versées.” The current Article 1671 A of the General Tax Code also sets a specific payment and declaration framework for those withholdings. That framework is not a shortcut for ordinary resident-employee PAS. Ask which legal basis applies before selecting the form.

Finally, separate the withholding tax from the employer’s own cost. PAS is collected from the employee’s taxable pay and remitted for the employee’s income tax. Employer social contributions, employee social deductions, payroll fees, and the gross salary are different accounting lines. A foreign parent should reconcile the payroll register, the intercompany recharge, the bank payment to the employee, and the tax remittance without netting them into one unexplained transfer.

B. Preserve evidence, correct errors, and manage liability after the first payment

The payslip is the employee’s primary evidence of what was earned, withheld, and paid. Article L. 3243-2 of the Labour Code requires the employer, when paying salary, to give a document called a payslip: “Lors du paiement du salaire, l’employeur remet … une pièce justificative dite bulletin de paie.” The official Article L. 3243-2 page also governs electronic delivery and the integrity, availability, confidentiality, and accessibility of electronic payslips.

Article R. 3243-1 supplies the content architecture. It begins: “Le bulletin de paie prévu à l’article L. 3243-2 comporte :” and then lists the employer, activity, collective agreement where applicable, employee, hours, gross remuneration, contributions, withholding base, withholding rate, withholding amount, net amount, payment date, and other mandatory information. The official Article R. 3243-1 page expressly includes the base, rate, and amount of the PAS deduction. A home-country payslip translated into English is not automatically a French-compliant payslip.

Archive the record for at least the statutory period. Article L. 3243-4 states: “L’employeur conserve un double des bulletins de paie … pendant cinq ans.” See the official Article L. 3243-4 page. Retention should cover the payslip, payroll calculation, rate response, declaration file, acknowledgement, payment proof, correction file, and the factual classification on which the route was chosen. Five years is a minimum for the cited payslip rule; other tax, accounting, corporate, or litigation rules can require longer retention.

Build a correction protocol before an error occurs. If the payroll system used the wrong rate, first determine whether the error is a rate-transmission issue, an employee-data issue, a net-taxable-base issue, or a declaration/payment issue. Then preserve the original calculation, record the correction date and reason, issue an amended payslip where required, transmit the corrective declaration through the same channel, and reconcile the amount actually remitted. The employee may need to contact the tax administration about personal tax information, but that does not transfer the employer’s reporting duty to the employee.

If the first declaration was missed, do not silently add the unpaid tax to a later payroll line. Escalate immediately to the payroll provider, the competent tax service, and the employer’s French adviser. The remedy may involve a late or corrective declaration, a payment of the withheld amount, late-payment consequences, and a written explanation. The correct procedure depends on whether the employer withheld money but failed to remit it, failed to withhold, filed wrong employee data, or used the wrong legal channel.

Article 1759-0 A of the General Tax Code provides a graduated fiscal penalty system. It covers omissions or inaccuracies, late filing, deliberate inaccuracies or omissions, and amounts withheld but deliberately neither declared nor paid. The official Article 1759-0 A page sets out the 5%, 10%, 40%, and 80% levels and the €250 minimum per declaration. The applicable level depends on the facts and the legal classification; it should not be treated as a price list for late compliance.

Further consequences may arise where a withholding is not declared or paid for more than the period specified by the criminal provisions. The official Article 1771 A page and the related provisions should be checked in their current version. A foreign board should understand that the absence of a French office does not make a French payroll risk invisible. The responsible entity, its directors, the payroll intermediary, and any designated representative can have different roles, and those roles should be documented before the first failure.

The evidence file should answer an auditor’s or judge’s questions in chronological order:

1. What facts led the company to conclude that the employee’s salary was taxable in France?
2. Why did the company select DSN, PASRAU, or a non-resident withholding route?
3. Which SIREN or SIRET and which legal name were used?
4. When was the professional tax account activated, and who could authorise payment?
5. When was the SEPA mandate tested and when did the bank debit occur?
6. When was the DPAE filed and acknowledged?
7. Which tax rate was returned, on what date, and how was it applied?
8. How was gross pay converted into the net taxable base?
9. What amount appeared on the payslip, the declaration, the ledger, and the bank payment?
10. What was corrected, by whom, through which declaration, and with what employee communication?

A first-payroll review should also look for issues that do not appear in the headline PAS amount. Check the collective agreement and employee classification, working-time data, taxable benefits, bonuses, equity awards, expense reimbursements, sick leave, termination payments, and any cross-border days. A foreign parent often sends a compensation policy in English; the French payroll must still map each item to the French payslip and reporting fields. If an item cannot be classified, flag it before payment rather than hiding it in a generic allowance.

Use a three-way reconciliation at month end. The first column is the payroll register: employee, period, taxable base, rate, and PAS amount. The second is the declaration acknowledgement: identifier, period, accepted amount, corrections, and rejection messages. The third is the bank evidence: salary payment, tax remittance, social-contribution payment, date, and reference. Any difference should have a ticket, an owner, and a resolution date. This simple control is particularly important where the parent pays the employee while a French provider files the declaration.

Cross-border responsibility should be allocated in the service agreement. State who verifies the legal classification, who collects the tax rate, who owns the SIRET and professional account, who files DSN or PASRAU, who makes the payment, who handles a rejection, who answers a URSSAF or tax-service request, and who keeps the evidence. A payroll provider can perform technical work, but the foreign employer should not assume that outsourcing the file transfers every statutory liability. The contract should contain an escalation deadline before each payment and a procedure for a rejected declaration.

The same discipline applies when the company changes structure. If a branch becomes a subsidiary, the new entity may need its own registration, account, employer declaration, payroll identifiers, and category mapping. If a subsidiary becomes the employer while the parent continues paying, the intercompany payment does not change the legal employer shown on the payslip. If the employee moves from France to another country, revisit both the tax source and social-security position before changing the reporting channel. A new employment contract is not enough; the administrative trail must move with it.

Conclusion

A foreign employer’s first French employee should not be placed into a payroll workflow by analogy with the parent company’s home country. The employer must first establish where the work is done, which entity employs and pays the worker, whether the salary is taxable in France, whether French social contributions are due, and whether the case uses ordinary PAS, PASRAU, or non-resident withholding. Registration, SIREN or SIRET identification, the professional tax account, the SEPA mandate, social affiliation, and the DPAE should be completed before the first salary.

The safest operating file connects the legal analysis to the payslip, declaration acknowledgement, bank payment, and correction log. DSN and PASRAU are not interchangeable labels, and the absence of a French establishment does not remove the need for a French reporting decision. When the facts involve remote work, secondment, a foreign tax-resident employee, a branch, a French subsidiary, equity compensation, or a change of employing entity, obtain a documented review before the first payment rather than repairing an undocumented payroll after an inspection.
