International Payroll in France: The Employer’s Compliance Guide

Running international payroll in France means you must register your company with the French social-security system, calculate and withhold both employer and employee social contributions, and file the monthly Déclaration Sociale Nominative (DSN) — even if your company has no legal entity in France. As the employer, you are responsible for accurate payslips, on-time contribution payments to URSSAF, and full compliance with the applicable collective bargaining agreement, regardless of where your headquarters sits.

This guide explains, from the employer’s standpoint, how French payroll works, what you owe, and where foreign companies most often get it wrong. DAIRIA Law advises and assists international employers in structuring compliant payroll operations in France.

What “International Payroll” Means Under French Law

When you hire an employee who works in France, French labour and social-security law generally applies to that employment relationship — the place of work, not the location of your headquarters, is decisive. This means your payroll obligations are set by the French Labour Code and the French Social Security Code, whatever payroll software or global provider you use.

You have three main structural options:

French legal entity (subsidiary or branch): You register directly, run payroll under your own SIRET number, and are the direct employer.
Foreign employer without an establishment in France: You may still employ someone in France without a local entity. In that case you use the simplified Titre firmes étrangères (TFE) scheme through URSSAF, which allows a foreign company to register and pay French social contributions remotely.
Employer of Record (EOR) / portage salarial: A third party is the legal employer and handles payroll. This transfers certain obligations but does not eliminate your exposure to co-employment or misclassification risk.

Each route carries different compliance duties. The common denominator is that the payslip, the contributions, and the working-time rules must satisfy French requirements.

French payroll is defined by high employer social charges. On top of the gross salary, employer contributions typically add roughly 40–45% of gross pay, while employee contributions withheld from gross pay are around 20–23%. These fund health insurance, retirement (basic and supplementary AGIRC-ARRCO), unemployment insurance, family benefits, workplace-accident coverage, and other schemes.

As the employer you must:

Register the employee before the first day of work via the Déclaration Préalable à l’Embauche (DPAE), which must be sent to URSSAF within the eight days preceding hiring. This obligation is set by Article L.1221-10 of the French Labour Code.
Deliver a compliant payslip. The mandatory content of the payslip is governed by Article R.3243-1 of the French Labour Code, which lists the information every bulletin de paie must contain.
Withhold employee contributions and pay both shares to the relevant bodies (URSSAF for most contributions, AGIRC-ARRCO for supplementary pension).
Operate the prélèvement à la source (PAS) income-tax withholding on behalf of the tax authority. This is an administrative collection duty carried out through payroll; the underlying tax rules themselves are outside the scope of labour-law advice.

Getting the contribution base wrong — for example, mishandling benefits in kind, expense reimbursements, or bonuses — is one of the most frequent triggers of a URSSAF audit and reassessment.

The Monthly DSN: Your Central Filing Obligation

The Déclaration Sociale Nominative (DSN) is the single monthly electronic declaration that consolidates all social data for each employee. It replaced dozens of separate filings and is mandatory for every employer running payroll in France. Through the DSN you report salaries, contributions, working time, and events such as sick leave, maternity leave, or termination.

Key points for foreign employers:

The DSN is filed monthly, typically by the 5th or 15th of the following month depending on company size.
“Event” DSNs (arrêt de travail, end of contract) must be transmitted within specific short deadlines.
Late or inaccurate DSNs generate automatic penalties and can flag your company for inspection.
Foreign employers using the TFE scheme benefit from a simplified declaration route, but the substance of the obligation remains.

You cannot outsource away responsibility: even if a provider files on your behalf, the employer of record on the DSN carries the legal liability for accuracy.

Collective Bargaining Agreements and Working Time

A critical mistake foreign HR teams make is treating French payroll as a purely arithmetic exercise. In reality, almost every employee in France is covered by a convention collective (industry-wide collective bargaining agreement) that can impose minimum salaries above the statutory minimum wage (SMIC), mandatory bonuses (such as a 13th-month payment or seniority premiums), specific paid-leave rules, and enhanced severance.

Working time also feeds directly into payroll:

The statutory working week is 35 hours. Hours beyond that are overtime and must be paid at increased rates, with the legal framework set out in Article L.3121-27 of the French Labour Code and following provisions.
Executives and autonomous employees may be placed under a forfait jours (day-count) arrangement, but only where the applicable collective agreement authorises it and strict conditions are met.
Paid leave accrues at 2.5 working days per month worked, i.e. five weeks per year.

Before you set a single salary line, you must identify the correct collective agreement (IDCC code) — it determines your true payroll cost. DAIRIA Law assists international employers in identifying the applicable convention and quantifying the real cost of a French hire.

Secondment vs. Local Hiring: Payroll Consequences

If you post an employee to France temporarily from another EU or non-EU country, the détachement (posting) rules may allow them to remain affiliated to their home social-security system, subject to an A1 certificate (within the EU) or a bilateral totalisation agreement. In that case French social charges may not apply, but French “hard core” labour rules — minimum wage, working time, health and safety — still do.

By contrast, a genuinely local hire is fully subject to French payroll. Misclassifying a permanent local role as a “posting” to avoid French contributions is a serious risk: URSSAF can reclassify the relationship, demand back contributions with penalties, and, in severe cases, pursue concealed-employment (travail dissimulé) sanctions. The posting-declaration obligation for employers sending workers to France is grounded in Article L.1262-2-1 of the French Labour Code.

FAQ

Do I need a French entity to run payroll for an employee in France?

No. A foreign company can employ someone in France without a local entity by registering with URSSAF under the firmes étrangères (TFE) scheme, or by using an Employer of Record. However, you still owe French social contributions, must issue compliant payslips, and must file the DSN. A local entity is only mandatory if your activity amounts to a permanent establishment.

As a rule of thumb, employer contributions add approximately 40–45% on top of gross salary, and employee contributions of roughly 20–23% are withheld from gross pay. The exact figures depend on salary level, the applicable collective agreement, and any available reductions on lower salaries. Always budget the total employer cost, not just the gross.

What is the DSN and who must file it?

The DSN (Déclaration Sociale Nominative) is the mandatory monthly electronic social declaration that every employer running payroll in France must transmit. It reports salaries, contributions, and payroll events for each employee. As the employer you remain legally responsible for its accuracy even when a payroll provider files it on your behalf.

Does the collective bargaining agreement affect my payroll costs?

Yes, significantly. The applicable convention collective can set minimum salaries above the statutory SMIC, require additional bonuses (such as a 13th month), and impose enhanced leave or severance rules. You must identify the correct agreement before setting salaries, because it directly determines your minimum legal payroll cost.

Can I keep a posted employee on their home payroll instead of French payroll?

Only for genuine temporary postings covered by an A1 certificate or a bilateral social-security agreement. Even then, French minimum-wage, working-time, and health-and-safety rules apply, and you must file a posting declaration. If the assignment is in reality a permanent local role, French payroll and contributions become fully due and reclassification penalties may follow.
