You have just received the Kbis<\/em> \u2014 the official registration certificate issued by the greffe<\/em>, the registry office of the French commercial court \u2014 and your name appears on it as pr\u00e9sident<\/em> of your new soci\u00e9t\u00e9 par actions simplifi\u00e9e<\/em> (SAS, the flexible French company form most foreign founders choose). A few weeks later, a second letter arrives, this time from URSSAF, the French body that collects social security contributions. It asks for money, sometimes a large amount, and it uses words you have never seen: assimil\u00e9 salari\u00e9<\/em>, travailleur non salari\u00e9<\/em> (TNS, the self-employed status), assiette forfaitaire<\/em> (a flat-rate calculation base), mise en demeure<\/em> (a formal demand to pay). This article explains, in plain English, which French social security regime applies to you from the day you are appointed, what your first bill is made of, and exactly how to react when URSSAF reassesses you. It covers both the SAS and its cousin the soci\u00e9t\u00e9 \u00e0 responsabilit\u00e9 limit\u00e9e<\/em> (SARL, the French limited liability company with stricter statutory rules), because many founders hesitate between the two and the social security answer is completely different. Every decisive statement below is anchored to the statute or ruling quoted beside it, so you can check each point yourself on L\u00e9gifrance, the official French legal database, or on the website of the Cour de cassation<\/em>, France’s highest civil court.<\/p>\n

I. Which Social Security Regime Applies When a Foreign Founder Runs a French Company<\/h2>\n

French law does not ask for your passport before affiliating you. It asks what mandate you hold, whether that mandate is paid, and how much of the capital you own. Three questions, three answers \u2014 and the wrong answer costs thousands of euros a year.<\/p>\n

A. Paid President of a SAS: Why You Join the General Regime<\/h3>\n

The SAS is managed by a president appointed under the conditions set by the articles of association. Article L. 227-6 of the Commercial Code<\/a> states: “La soci\u00e9t\u00e9 est repr\u00e9sent\u00e9e \u00e0 l’\u00e9gard des tiers par un pr\u00e9sident d\u00e9sign\u00e9 dans les conditions pr\u00e9vues par les statuts” \u2014 the company is represented toward third parties by a president appointed as the articles provide. That president may be a foreigner, may live abroad, and may hold 100 percent of the shares. None of that changes the social security analysis. What matters is the remuneration attached to the mandate.<\/p>\n

If you are paid as president \u2014 or as directeur g\u00e9n\u00e9ral<\/em> (chief executive) or directeur g\u00e9n\u00e9ral d\u00e9l\u00e9gu\u00e9<\/em> (deputy chief executive) of the SAS \u2014 you are brought inside the r\u00e9gime g\u00e9n\u00e9ral<\/em>, the general social security scheme that covers employees. Article L. 311-3 of the Social Security Code<\/a> lists: “Les pr\u00e9sidents et dirigeants des soci\u00e9t\u00e9s par actions simplifi\u00e9es et des soci\u00e9t\u00e9s d’exercice lib\u00e9ral par actions simplifi\u00e9es” \u2014 the presidents and senior officers of SAS companies are compulsorily covered. You are then called an assimil\u00e9 salari\u00e9<\/em>: you pay roughly like an employee for health, retirement (basic state pension), family benefits, workplace accidents and the CSG-CRDS levies, but you do not get unemployment insurance, and you cannot claim paid-leave indemnities from an employer who is yourself. Your contributions are computed on your actual remuneration and, as article L. 242-1 of the Social Security Code<\/a> provides: “Les cotisations de s\u00e9curit\u00e9 sociale dues au titre de l’affiliation au r\u00e9gime g\u00e9n\u00e9ral des personnes mentionn\u00e9es aux articles L. 311-2 et L. 311-3 sont assises sur les revenus d’activit\u00e9” \u2014 contributions due for persons covered under articles L. 311-2 and L. 311-3 are assessed on earned income. In practice the company withholds your share each month through the d\u00e9claration sociale nominative<\/em> (DSN, the monthly online payroll return every French employer files) and pays the employer’s share on top, exactly as it would for a salaried executive.<\/p>\n

The Cour de cassation<\/em> confirmed this architecture in a ruling every foreign president should know. In Cass. 2nd civil chamber, 5 June 2025, no. 23-13.887<\/a>, the Court recalled: “Selon l’article L. 311-3, 23\u00b0, du code de la s\u00e9curit\u00e9 sociale, dans sa r\u00e9daction applicable au litige, sont obligatoirement affili\u00e9s aux assurances sociales du r\u00e9gime g\u00e9n\u00e9ral les pr\u00e9sidents et dirigeants des soci\u00e9t\u00e9s par actions simplifi\u00e9es et de soci\u00e9t\u00e9s d’exercice lib\u00e9ral par actions simplifi\u00e9es” \u2014 under article L. 311-3, 23\u00b0, the presidents and officers of SAS companies are compulsorily affiliated to the general scheme. The case concerned a chairman of a supervisory board whose company argued he only supervised and therefore owed nothing. The Court drew the line precisely: “ayant pour seule mission de contr\u00f4ler les organes de direction de la soci\u00e9t\u00e9 sans en assumer la gestion, les membres du conseil de surveillance ne sont en principe pas affili\u00e9s aux assurances sociales du r\u00e9gime g\u00e9n\u00e9ral, sauf \u00e0 d\u00e9montrer qu’ils exercent en r\u00e9alit\u00e9 une fonction de direction” \u2014 members of a supervisory board, whose sole task is to oversee the management bodies without managing, are in principle not affiliated to the general scheme, unless it is shown that they actually perform a management function. Because the chairman in that case was registered in the BODACC \u2014 the Bulletin officiel des annonces civiles et commerciales<\/em>, the official gazette where company appointments are published \u2014 as a person habitually empowered to bind the company, and designated as an officer on the M2 amendment form filed with the company registry, the reassessment was upheld. The lesson for a foreign founder is direct: if your name is published as the person who runs the SAS and you draw pay, URSSAF will affiliate you to the general regime, and the courts will back it. Conversely, a purely supervisory role with no management power and no pay does not trigger affiliation \u2014 but you must be able to prove the absence of any real management function, and a BODACC entry describing you as empowered to bind the company will be used against you.<\/p>\n

Two practical consequences follow. First, an unpaid SAS president owes no social security contributions on the mandate itself: no salary, no assessment base, no bill \u2014 though you remain liable for contributions on any separate employment contract only if that contract reflects genuine subordinate work, a situation URSSAF examines with suspicion when the employee is also the president. Second, dividends you receive as a shareholder of your SAS are not remuneration for the mandate and do not enter the general-regime base: the company owes contributions only on what you earn as an officer, a boundary the courts police strictly, as the second ruling discussed below confirms.<\/p>\n

B. Majority Manager of a SARL: Why You Pay as Self-Employed<\/h3>\n

Choose a SARL instead and the logic flips. Article L. 223-18 of the Commercial Code<\/a> opens with a simple rule: “La soci\u00e9t\u00e9 \u00e0 responsabilit\u00e9 limit\u00e9e est g\u00e9r\u00e9e par une ou plusieurs personnes physiques” \u2014 the SARL is managed by one or more natural persons, called g\u00e9rants<\/em> (managers). A g\u00e9rant<\/em> who, alone or together with co-managers, holds more than half of the capital \u2014 counting shares owned by a spouse, civil partner or minor children \u2014 is classified as a travailleur non salari\u00e9<\/em> (TNS), a self-employed worker. A minority or non-shareholder g\u00e9rant<\/em> who is paid falls instead under the general regime through article L. 311-3, 11\u00b0, of the Social Security Code<\/a>, which covers managers of SARLs who do not together own more than half of the capital. So the capital table decides your regime: majority manager means the independent workers’ scheme; minority paid manager means the general scheme like a SAS president.<\/p>\n

The independent scheme is administered through the general system since the former R\u00e9gime social des ind\u00e9pendants<\/em> was absorbed, but its economics remain distinct. Article L. 611-1 of the Social Security Code<\/a> defines its personal scope, starting with: “Les travailleurs non salari\u00e9s qui ne sont pas affili\u00e9s au r\u00e9gime mentionn\u00e9 au 3\u00b0 de l’article L. 722-8 du code rural et de la p\u00eache maritime” \u2014 non-salaried workers who are not covered by the agricultural scheme. If you are a majority g\u00e9rant<\/em>, you belong here by operation of law from the day of your appointment, whether or not URSSAF has written to you yet. The base is your professional income, and article L. 131-6 of the Social Security Code<\/a> provides: “Les cotisations de s\u00e9curit\u00e9 sociale dues par les travailleurs ind\u00e9pendants non agricoles ne relevant pas du dispositif pr\u00e9vu \u00e0 l’article L. 613-7 sont assises sur l’assiette d\u00e9finie \u00e0 l’article L. 136-3” \u2014 contributions owed by non-agricultural independent workers outside the micro-regime of article L. 613-7 are assessed on the base defined at article L. 136-3, essentially your business profit. That base includes dividends paid to a majority g\u00e9rant<\/em> above a statutory threshold, which is why founders who planned to “take dividends instead of salary” sometimes discover that the strategy barely reduces the bill in a SARL \u2014 whereas in a SAS, dividends paid to the president escape social contributions. This single asymmetry drives many foreign founders toward the SAS, and it should be priced before you choose the company form, not after the first reassessment.<\/p>\n

Timing matters as much as the rate. Article L. 131-6-2 of the Social Security Code<\/a> makes these contributions due annually, then states: “Elles sont calcul\u00e9es, \u00e0 titre provisionnel, sur la base de l’assiette de cotisations pr\u00e9vue \u00e0 l’article L. 131-6 pour l’avant-derni\u00e8re ann\u00e9e” \u2014 they are calculated provisionally on the base of the year before last. For newcomers the statute adds: “Pour les deux premi\u00e8res ann\u00e9es d’activit\u00e9, les cotisations provisionnelles sont calcul\u00e9es sur la base d’une assiette forfaitaire fix\u00e9e par d\u00e9cret” \u2014 for the first two years of activity, provisional contributions are calculated on a flat-rate base set by decree. Concretely, a foreign founder who becomes majority g\u00e9rant<\/em> in September receives provisional bills computed on that decree base even though the company has earned almost nothing yet; when the real income for the year is finally known, URSSAF recalculates and either claims the balance or credits the overpayment. The first-year shock is therefore normal, but it must be budgeted: founders who leave the letters unopened return a year later to a mise en demeure<\/em> loaded with surcharges.<\/p>\n

The boundary between mandate income and other income is policed just as strictly in the SARL world. In Cass. 2nd civil chamber, 24 June 2021, no. 20-11.723<\/a> \u2014 a case that involved, tellingly, a British limited company operating in France \u2014 URSSAF had folded into the contribution base a fee the manager received under a separate location-g\u00e9rance<\/em> agreement (a contract leasing his clientele to the company). The Cour de cassation<\/em> quashed the reassessment, holding: “Il r\u00e9sulte de la combinaison des deux premiers de ces textes qu’une soci\u00e9t\u00e9 ne peut \u00eatre tenue au paiement des cotisations dues pour son g\u00e9rant, lorsqu’il est assujetti au r\u00e9gime g\u00e9n\u00e9ral en application du troisi\u00e8me, que sur la r\u00e9mun\u00e9ration per\u00e7ue par ce dernier en contrepartie ou \u00e0 l’occasion de ses fonctions” \u2014 a company can be held liable for contributions due for its manager, when he is covered by the general regime, only on remuneration received in return for or in connection with his functions. Sums paid under an independent commercial arrangement, not as consideration for the corporate office, fall outside the base. For a foreign founder this is both a shield and a warning: keep the mandate, the employment relationship if any, and the commercial contracts in three separate, properly documented piles, because URSSAF will try to merge them and only clean paperwork lets a court split them apart.<\/p>\n

One last situation deserves a clear answer because founders ask it constantly: the unpaid officer. A SAS president or SARL g\u00e9rant<\/em> who receives strictly zero remuneration \u2014 no salary, no benefits in kind, no disguised payment \u2014 owes no contributions on that empty mandate in either regime, since both bases (earned income under article L. 242-1<\/a>, professional income under article L. 131-6<\/a>) are zero. But the exemption is fragile: any payment recharacterised as remuneration \u2014 current-account withdrawals treated as advances on salary, personal expenses paid by the company, fees routed through a foreign vehicle \u2014 resurrects the debt with retroactive effect. Founders resident abroad sometimes assume distance protects them; it does not. Affiliation follows the French mandate, and URSSAF notifies the company at its French registered office regardless of where the officer sleeps.<\/p>\n

II. Your First URSSAF Bill in France: Amount, Calendar, and How to Contest It<\/h2>\n

Knowing your regime is half the battle. The other half is reading the bill, paying on time, and reacting correctly when the amount looks wrong. Foreign founders lose most of their disputes not on the law but on missed deadlines and unanswered letters.<\/p>\n

A. How Much You Pay and When the Money Leaves Your Account<\/h3>\n

Start with the SAS president, because the mechanics resemble payroll. Each month (or quarter for very small companies that opt for quarterly settlement), the company declares your gross remuneration in the DSN and pays both the employee’s share \u2014 withheld from your pay \u2014 and the employer’s share, which in France represents the larger part of the total. The exact overall burden moves every year with the plafond de la s\u00e9curit\u00e9 sociale<\/em> (the annually revised ceiling that caps several contribution bands) and the rates voted in the social security budget, so resist any blog post quoting a fixed percentage as eternal truth: check the current scales on the official urssaf.fr rate pages and your accountant’s payslip simulation before signing a remuneration level into the minutes. What never changes is the base rule quoted above \u2014 contributions sit on earned income from the mandate \u2014 and the calendar: DSN filing and payment fall due in the days following each pay period, with late payment triggering surcharges that compound quickly. A founder who pays herself irregularly, in lump sums decided abroad, still owes contributions for the period to which the income attaches, and URSSAF reconstitutes the timeline from the company’s accounts during an audit.<\/p>\n

Now the SARL majority g\u00e9rant<\/em>. Here there is no payslip and no DSN for the mandate: you declare your professional income once a year through the single tax-and-social return (d\u00e9claration de revenus<\/em> shared with the tax administration), and URSSAF bills you directly as an individual. Year one and year two run on the flat-rate provisional base set by decree, which means you pay even if the company made no profit \u2014 a frequent shock for founders who assumed “no profit, no contributions.” From year three onward, the provisional bill is computed on the income of the year before last and regularised once the final income is known, with the statute’s mechanism operating automatically: overpayments generate a credit against future bills, underpayments generate a balance due, and persistent underestimation can draw penalties. Keep every appel de cotisations<\/em> (the contribution notice URSSAF sends), reconcile it against your tax return, and instruct your accountant to request a modulation of the provisional base the moment your income drops \u2014 waiting for the automatic regularisation means lending URSSAF money interest-free for up to two years, while overpaying nothing means risking a shortfall plus surcharges.<\/p>\n

Three cost traps specific to foreign founders deserve emphasis. First, the double-billing illusion: a founder who is simultaneously president of a French SAS and self-employed in another country sometimes pays social charges twice on the same income. Within the European Union and the European Economic Area, the coordination regulations designate a single competent state \u2014 generally where the substantial activity is performed \u2014 and an A1 certificate proves it; with non-EU states, only a bilateral social security agreement can prevent duplication, and the United States, the United Kingdom and most Gulf states each have their own position. Ask for the certificate before the first payroll run, not after URSSAF bills you, because refunds across borders take years. Second, the minimum-contribution floor: several contributions (notably basic retirement and daily sickness allowances for the self-employed) carry annual minimums, so a token salary of one euro does not buy coverage at one euro of cost \u2014 it buys the floor. Third, the CSG-CRDS layer: these levies apply to a slightly wider base than classic contributions and follow their own rules, which is why the “total charge” on a payslip always exceeds the sum of the contribution lines a founder first adds up. None of these traps is a reason to avoid France; each is a reason to simulate the full cost with an accountant before fixing your remuneration in the shareholders’ minutes, because minutes are easy to adopt and painful to unwind.<\/p>\n

B. How to Contest a Reassessment After a URSSAF Audit<\/h3>\n

Most disputes begin the same way: an auditor examines several financial years, then sends a lettre d’observations<\/em> (the letter setting out the proposed reassessment, point by point). This letter is the most important document of the entire dispute. You have a short window \u2014 the deadline printed on the letter itself \u2014 to reply with facts, contracts and accounting evidence. Silence at this stage is routinely fatal: courts treat unanswered observations as accepted, and the later judges will ask what you said at the time. Answer every point, attach the articles of association, the minutes fixing remuneration, the BODACC publication, the M2 form, the employment contract if one exists, and the commercial agreements you want kept out of the base. If you are a SAS president arguing that part of the sums are dividends, produce the shareholders’ resolution distributing them; if you are a manager arguing that fees came from a separate contract, produce that contract and the invoices, exactly the sorting exercise the 2021 ruling above rewards.<\/p>\n

If URSSAF maintains its position, it issues a mise en demeure<\/em>, the formal demand that makes the debt enforceable and starts the clock for court review. From receipt, you must first file an administrative appeal before the commission de recours amiable<\/em> (CRA, the internal appeals board of the URSSAF fund) within the period stated on the demand \u2014 this prior appeal is mandatory and missing it closes the courthouse door. Frame the CRA petition as a lawyer would a pleading: identify each contested head of reassessment, cite the article that governs it, quote the ruling that supports you, and quantify the alternative base you accept. The two decisions examined in this article give you ready-made paragraphs: for an SAS officer, the 2025 ruling’s test \u2014 supervision alone is not affiliation, real management power is \u2014 and for a SARL manager, the 2021 ruling’s boundary \u2014 only remuneration received in return for or in connection with the functions enters the base. Attach everything, because the CRA decides on the file and rarely holds hearings.<\/p>\n

If the CRA rejects the appeal expressly or stays silent past its decision period, the dispute moves to the tribunal judiciaire<\/em> (the ordinary civil court, whose socially specialised chamber hears social security cases), and the enforcement mechanism becomes the contrainte<\/em> \u2014 an enforceable order URSSAF issues to recover the debt, which you can oppose before that same court within its stated deadline. Three discipline rules decide these cases more often than doctrine. First, never pay the contrainte<\/em> without marking the payment as made under protest and continuing the challenge: an unreserved payment reads as acquiescence. Second, keep the company’s registered office monitored \u2014 URSSAF notifies the company in France, and founders living abroad discover mises en demeure<\/em> months late in unopened mail, long after the CRA window has closed. Appoint a person in France to open, scan and forward every administrative letter within days. Third, preserve evidence of actual functions from day one: board minutes describing who decided what, delegation tables, email trails showing who signed investments. The 2025 case turned precisely on such traces \u2014 BODACC wording, the M2 form, investment powers \u2014 and your file will be judged the same way. Founders who build this paper trail when everything is calm win the audit three years later; founders who reconstruct it after the lettre d’observations<\/em> arrives usually lose.<\/p>\n

Conclusion<\/h2>\n

A foreign founder who takes office in a French company chooses a social security destiny at the same time: paid president of a SAS means the general regime on all mandate remuneration, with dividends outside the base; majority manager of a SARL means the self-employed regime on professional income, with provisional flat-rate bills in the first two years and automatic regularisation afterward; unpaid mandates in either form mean no contributions until a payment is recharacterised as pay. The statutes draw these lines \u2014 articles L. 311-3, L. 242-1, L. 131-6 and L. 131-6-2 of the Social Security Code, articles L. 227-6 and L. 223-18 of the Commercial Code \u2014 and the Cour de cassation<\/em> enforces them, affiliating SAS officers who actually manage (5 June 2025, no. 23-13.887) while refusing to let URSSAF tax income unconnected to the mandate (24 June 2021, no. 20-11.723). Price the regime before choosing the company form, simulate the full first-year cost with an accountant, register for the correct declaration channel from month one, and answer every URSSAF letter inside its printed deadline through the CRA and, if needed, the tribunal judiciaire<\/em>. Run this way, the French system is predictable and contestable; ignored, it compounds silently until the contrainte<\/em> arrives.<\/p>\n
