You formed your French company without leaving home. The Kbis — the official registration certificate that proves your company exists — arrived by email, the greffe, the registry office of the commercial court, recorded your articles, and your first invoices went out with French VAT. Then a new message lands in your online tax account: your company owes impôt sur les sociétés, usually shortened to IS, the French corporate income tax, and the first instalments are already due. Many foreign founders discover at that moment that French corporate tax does not wait for you to move to France, open a French office, or even close your first profitable year. It runs on its own calendar, with quarterly payments computed on last year’s profit, a full tax return bundle called the liasse fiscale, and penalties that grow every month you ignore them. This guide explains, for a founder or parent company running a French SAS, SASU or SARL from London, New York, Dubai, Singapore or anywhere else, who pays IS and on what profits, the standard 25% rate, the four advance payments known as acomptes, the filing deadline for the liasse fiscale, and exactly how to fix a late filing from abroad before interest and surcharges pile up.
I. Does a French Company Owned From Abroad Pay Corporate Tax in France
The short answer is yes in almost every case that matters to a foreign founder. Once your company is registered in France, it becomes a French taxpayer for the profits its French business earns, even if every shareholder and director lives outside France and every board decision is taken over video calls. The sections below set out which companies fall inside the tax, which profits France taxes, and the rate applied to them.
A. Which Companies Pay IS in France and at What Rate
Article 206 of the French General Tax Code (Code général des impôts) lists the companies liable to corporate tax: “sont passibles de l’impôt sur les sociétés, quel que soit leur objet, les sociétés anonymes, les sociétés en commandite par actions, les sociétés à responsabilité limitée n’ayant pas opté pour le régime fiscal des sociétés de personnes dans les conditions prévues au IV de l’article 3 du décret n° 55-594 du 20 mai 1955 modifié” (Article 206, General Tax Code, in force on 13 October 2026). The same article sweeps up the remaining vehicles foreign investors actually use, since it adds “toutes autres personnes morales se livrant à une exploitation ou à des opérations de caractère lucratif” (Article 206, General Tax Code), which covers the SAS (société par actions simplifiée, the flexible joint-stock company almost every foreign founder chooses) and the SASU (its one-shareholder version). In practice, then, a French SAS, SASU, SA or SARL that has not validly elected for partnership taxation pays IS as the default. If you deliberately chose a partnership-tax option for your SARL or a transparent vehicle, confirm in writing with your accountant that the option was actually recorded, because the tax office applies the default corporate-tax regime whenever the option is missing from the file.
The second question is which profits France taxes when the owners are abroad. Article 209 of the same code answers it with the territoriality principle: French corporate tax takes into account “en tenant compte uniquement des bénéfices réalisés dans les entreprises exploitées en France” (Article 209, General Tax Code, in force on 13 October 2026), alongside profits whose taxation is attributed to France by a double-tax treaty. Concretely, the profits your French company earns through its French activity — sales to French customers, services performed from France, rent from French premises — are taxable in France even if the money is immediately upstreamed to a foreign parent or the shareholders never set foot in the country. Conversely, profits earned by a genuinely separate foreign branch of your French company are generally outside French IS, though that carve-out raises its own evidence questions and you should document where each stream of profit is actually generated. Where a treaty allocates taxing rights differently, for example on certain cross-border dividends, interest or royalties, the treaty applies, but it never removes the French company itself from IS on its French operating profit.
The rate is straightforward for most founders. Article 219 of the General Tax Code states: “Le taux normal de l’impôt est fixé à 25 %.” (Article 219, General Tax Code, in force on 13 October 2026). That 25% standard rate applies to the taxable profit computed under French tax rules, which start from your accounting profit and then apply a long series of tax adjustments for items such as non-deductible penalties, thin-capitalisation interest limits, depreciation restatements and loss carry-forwards. Article 219 also organises separate or reduced rates for specific categories of profit, including long-term capital gains on certain holdings and income from qualifying innovation, and it provides a reduced rate for qualifying small companies within a capped slice of profit. Those thresholds and categories change over time, so before you budget, open the in-force version of Article 219 on Légifrance and the business tax pages of the official portal at impots.gouv.fr rather than relying on last year’s blog post. For a first profitable year, most foreign-owned SMEs simply apply 25% to the estimated taxable result and treat any reduced slice as a welcome correction, not as the plan.
Two practical consequences follow for founders abroad. First, French IS is a tax on the company, not on you personally: the bill is issued in the company’s online professional tax account (espace professionnel on impots.gouv.fr), must be paid from company funds, and your personal foreign bank account does not settle it. Second, the taxable result is built on French accounts. Article L123-12 of the Commercial Code requires that “Toute personne physique ou morale ayant la qualité de commerçant doit procéder à l’enregistrement comptable des mouvements affectant le patrimoine de son entreprise.” (Article L123-12, Commercial Code, in force on 13 October 2026) and that “Elle doit établir des comptes annuels à la clôture de l’exercice au vu des enregistrements comptables et de l’inventaire.” (Article L123-12, Commercial Code). If your bookkeeping is kept abroad in another language or under another GAAP, your French accountant must still produce French annual accounts — balance sheet (bilan), profit and loss statement (compte de résultat) and notes (annexe) — because those accounts are the starting point of the IS computation. If you are still at the creation stage, our step-by-step guide to setting up a company in France as a foreign founder, from bank account to Kbis, VAT and first hire explains how the registration, the company tax account and the first filings fit together.
B. When to Pay IS Acomptes in France: March, June, September and December
The feature of French corporate tax that surprises foreign founders most is that you pay most of the year’s tax before the year is over, in four advance instalments called acomptes. Article 1668 of the General Tax Code provides: “L’impôt sur les sociétés donne lieu au versement, au comptable public compétent, d’acomptes trimestriels déterminés à partir des résultats du dernier exercice clos.” (Article 1668, General Tax Code, in force on 13 October 2026). In plain terms, each instalment is computed from the profit of the last closed financial year, and the four instalments together approximate the IS due on that past profit. When the current year’s return is finally filed, the company pays only the balance (solde) if the real tax exceeds the instalments, or carries forward the excess if it overpaid. The calendar is fixed by the same article: “Les paiements doivent être effectués au plus tard les 15 mars, 15 juin, 15 septembre et 15 décembre de chaque année.” (Article 1668, General Tax Code). A company whose financial year ends on 31 December therefore pays its four instalments on 15 March, 15 June, 15 September and 15 December of the same year the profit is being earned, long before the return is filed the following spring.
There is one important piece of relief for new companies. Article 1668 states that “Les sociétés nouvellement créées ou nouvellement soumises, de plein droit ou sur option, à l’impôt sur les sociétés sont dispensées du versement d’acomptes au cours de leur premier exercice d’activité ou de leur première période d’imposition arrêtée conformément au deuxième alinéa du I de l’article 209” (Article 1668, General Tax Code). Your brand-new SAS therefore pays no quarterly instalments during its very first financial year; the whole first-year tax is settled as a single balance when the first return is filed. The shock arrives in year two: from the second year on, instalments are computed on the first year’s result, and if year one was strongly profitable, the March, June, September and December payments of year two can feel very large, especially if year-two trading has slowed. Founders abroad should model this cash-flow wall twelve months ahead and keep the reserve inside the French company account, because the SIE — the service des impôts des entreprises, the corporate tax office that manages your file — will not waive instalments simply because the shareholders live overseas or the group treasury sits in another currency.
Paying from abroad is entirely possible but requires setup. IS and its instalments are paid online from the company’s espace professionnel on impots.gouv.fr, normally by SEPA direct debit tied to a bank account the tax office knows. A foreign euro account can work for SEPA debits, but mismatches between the declared account, the company name exactly as registered, and the mandate often cause rejected debits, and a rejected debit counts as a missed deadline with interest running. The reliable pattern is to register the French company bank account used at incorporation for tax debits as soon as the Kbis arrives, test the mandate with the first payment, and keep a euro buffer covering at least one instalment. If the group funds the French subsidiary from abroad, move the cash as equity or documented intra-group loans well before each quarterly date rather than wiring it the same week, because a late-arriving transfer is not a legal excuse for a late instalment. Keep every payment receipt from the online account: in a later dispute about dates, the timestamped receipt is the proof the tax office accepts.
Finally, understand how instalments interact with credits. French or foreign withholding tax suffered by the company on certain investment income can be credited against IS: Article 220 provides that “Sur justifications, la retenue à la source à laquelle ont donné ouverture les revenus des capitaux mobiliers” (Article 220, General Tax Code, in force on 13 October 2026) is credited against the corporate tax due, within the fraction of the tax corresponding to that income. Keep the withholding certificates your bank or paying agent issues, hand them to your accountant before the return is prepared, and never assume a foreign tax credit applies automatically: credits need paperwork, they are claimed on the return, and undocumented claims are routinely rejected on audit. The same discipline applies to loss carry-forwards from a difficult first year, which can reduce year-two instalments only through the formal computation, not by a unilateral decision to skip a quarterly payment.
II. How to File and Pay French Corporate Tax From Abroad
Knowing the rate and the instalment dates is only half the job. The other half is filing the correct return, in the correct electronic form, by the correct day, and paying the balance from outside France. Miss the filing and a separate machinery of interest, surcharges and extended audit windows starts moving. This second part walks through the filing itself and then through the real cost of lateness and the repair plan.
A. How to File the Liasse Fiscale From Abroad: Deadline and Documents
The corporate tax return in France is not a short form; it is the liasse fiscale, a bundle built around tax form 2065 with tables reconciling your accounts to the taxable result, plus the annual accounts themselves and supporting schedules. Article 223 of the General Tax Code sets the filing rule: “la déclaration du bénéfice ou du déficit est faite dans les trois mois de la clôture de l’exercice.” (Article 223, General Tax Code, in force on 13 October 2026). For the standard case of a financial year ending on 31 December, the same article fixes the practical deadline every founder memorises: “Si l’exercice est clos le 31 décembre ou si aucun exercice n’est clos au cours d’une année, la déclaration est à déposer au plus tard le deuxième jour ouvré suivant le 1er mai.” (Article 223, General Tax Code). A company closing on 31 December 2025 therefore files its corporate tax return at the start of May 2026, and a company with an off-calendar year-end counts three months from its own closing date.
Filing is electronic and, for a founder abroad, runs through a professional. The liasse fiscale is transmitted under the TDFC/EDI procedure (transfert des données fiscales et comptables), in practice by your French accountant (expert-comptable) or an authorised filing provider, using software that generates the coded tables the tax office systems expect. You do not mail paper from London or Dubai. Your job as the non-resident director is to make the filing possible: sign the engagement letter, approve the accounts in a documented decision, provide the trial balance and supporting records in usable form, confirm related-party transactions with the foreign parent, and return the validation signature the accountant requests before transmission. If your group auditor works only in English under IFRS, plan a conversion step: the French return starts from French statutory accounts, and an IFRS consolidation pack alone will not transmit.
Do not confuse the tax filing with the company-law filing of the same accounts. Approving the accounts at the annual meeting and depositing them at the greffe for publication is a separate corporate duty with its own timetable, explained in our guide to the annual legal calendar of a French company run from abroad. A company can be perfectly current at the tax office and late at the greffe, or the reverse, and each lateness carries its own sanction. Likewise, VAT returns, payroll declarations (DSN, the monthly social data return sent to URSSAF, the social-security collection agency) and the local business tax (CFE, cotisation foncière des entreprises) run on independent calendars. Foreign founders who treat the May IS return as the only deadline of the year are the ones who discover in November that another tax has been quietly generating penalties for months. Keep one consolidated calendar for IS instalments, the liasse fiscale, VAT, payroll and CFE, and reconcile it with your accountant every quarter.
The balance payment follows the return. After the four acomptes are credited, the remaining solde is paid through the online professional account, and any overpayment is carried forward against future instalments rather than refunded automatically. Check the payment notice line by line before validating: verify the company name, the SIREN number (the nine-digit official company identifier issued at registration), the financial year concerned, and the split between instalments already paid and the balance claimed. Errors in year references are common when a company changes its closing date or files its first return late, and paying the wrong year’s notice leaves the correct year’s debt open with interest running. The official business pages at service-public.fr for professionals and the guides on impots.gouv.fr describe the current online procedures, and the one-stop company formalities portal at formalites.entreprises.gouv.fr with the INPI document the registration side whenever you need to confirm your company’s official data. When anything on the notice looks wrong — a missing instalment you actually paid, a year that is not yours, a company identifier that does not match your Kbis — stop, keep screenshots, and have the accountant query the SIE through the secure messaging of the professional account before the payment deadline rather than after.
B. What Happens If You File IS Late in France and How to Fix It
Late filing triggers two separate costs that stack on top of each other: interest for the time the Treasury waited, and a surcharge for the breach itself. The interest rule in Article 1727 of the General Tax Code is automatic: “Toute créance de nature fiscale, dont l’établissement ou le recouvrement incombe aux administrations fiscales, qui n’a pas été acquittée dans le délai légal donne lieu au versement d’un intérêt de retard.” (Article 1727, General Tax Code, in force on 13 October 2026). Interest runs month by month on the unpaid amount and no reminder letter is needed to start it. On top of interest, Article 1728 punishes the missing return itself: “Le défaut de production dans les délais prescrits d’une déclaration ou d’un acte comportant l’indication d’éléments à retenir pour l’assiette ou la liquidation de l’impôt entraîne l’application, sur le montant des droits mis à la charge du contribuable ou résultant de la déclaration ou de l’acte déposé tardivement, d’une majoration de :” (Article 1728, General Tax Code, in force on 13 October 2026). The scale then depends on your reaction to the formal demand (mise en demeure): “10 % en l’absence de mise en demeure ou en cas de dépôt de la déclaration ou de l’acte dans les trente jours suivant la réception d’une mise en demeure d’avoir à le produire dans ce délai” (Article 1728, General Tax Code), rising to “40 % lorsque la déclaration ou l’acte n’a pas été déposé dans les trente jours suivant la réception d’une mise en demeure d’avoir à le produire dans ce délai” (Article 1728, General Tax Code), with an 80% rate reserved for hidden-activity cases. A founder who files three weeks late without any demand letter therefore faces 10% plus interest; a founder who ignores the demand letter for two months faces 40% plus interest on the same tax.
Lateness also extends how long the tax office can look backwards. Article L169 of the Tax Procedures Book (Livre des procédures fiscales) sets the standard audit window: “Pour l’impôt sur le revenu et l’impôt sur les sociétés, le droit de reprise de l’administration des impôts s’exerce jusqu’à la fin de la troisième année qui suit celle au titre de laquelle l’imposition est due.” (Article L169, Tax Procedures Book, in force on 13 October 2026). That three-year window stretches to ten years where hidden activity is involved, which is why an unfiled return combined with undeclared French operations is the most dangerous configuration a foreign-owned company can be in: the file stays open for a decade and every later audit starts from the presumption that something was concealed. Filing late is always better than never filing, because the return starts the clock running toward closure and demonstrates that the company is identifiable, reachable and keeping records.
If you are already late, work through a repair plan in this order from abroad. First, establish the exact position: ask your accountant to list, year by year, which returns are missing, which instalments were paid, and which notices the SIE has issued, including any mise en demeure with its receipt date, since the 30-day window for the 10% rate runs from that date. Second, file the missing liasse fiscale returns before paying anything else, because the surcharge percentage applies to the assessed rights and only a filed return fixes the base. Third, pay the oldest principal first and keep every receipt, since interest stops accruing on amounts actually paid. Fourth, once the file is current, request relief where the facts support it: interest can sometimes be reduced on valid grounds and surcharges can be moderated where the company shows good faith, a first offence and a spontaneous filing, but such requests succeed only with a documented story — new accountant engaged, internal reorganisation completed, payment made before the demand — not with a bare plea of distance. If the file has already moved to enforced collection with seizure notices, our companion guide on an unpaid French tax bill received from abroad, from notice to seizure and how to contest explains the collection-side defences that run alongside the filing repair described here.
Three habits prevent the next lateness. Give your accountant a durable mandate and a reliable document channel that survives changes of CFO or email provider, because most foreign-owned files go late when the person who knew the portal password leaves. Calendar the four instalment dates and the return deadline as immovable board-level dates, with a cash check thirty days before each one, so group funding transfers from the parent arrive before the debit, not after. Finally, read every letter in the professional account’s secure messaging at least monthly, since French procedure runs on short deadlines counted from electronic notification, and a mise en demeure sitting unread for five weeks is the difference between a 10% and a 40% surcharge. The BODACC — the official bulletin publishing company life events — will not warn you about your tax file; only your own calendar and your accountant will.
Conclusion
French corporate tax follows your company, not your passport. A French SAS or SARL run entirely from abroad pays IS on the profits of its French business at the standard 25% rate set by Article 219, prepays that tax in four quarterly acomptes dated 15 March, 15 June, 15 September and 15 December under Article 1668, files its liasse fiscale within three months of closing — or by the second working day after 1 May for a 31 December year-end — under Article 223, and faces automatic late interest under Article 1727 plus 10% to 40% surcharges under Article 1728 when it files late. The first year brings a single pause, the instalment exemption for newly created companies, and then the normal machinery starts. Founders who keep French accounts that support the return, fund the quarterly dates from inside the French account, file electronically through their accountant before the deadline, and repair any lateness by filing first and paying oldest-first keep the cost of IS at the tax itself. Those who wait for the tax office to teach them the calendar pay the tuition in interest, surcharges and extended audit windows.
