You live in London, New York, Dubai or Singapore, your French company needs 80,000 euros to fit out its premises, hire its first employee or survive a late-paying customer, and the French bank will not lend to a company with one year of accounts and a director living abroad. So you wire your own money to the company and tell your accountant to book it as a shareholder loan. Months later, three surprises arrive together: the interest you charged is partly non-deductible, the repayment you expected is blocked because the loan agreement says nothing about maturity, and the French payer withholds tax on the interest before it reaches your foreign account. Financing your own French company from abroad is the most common funding route foreign founders use, and also the most reclassified one, because a single wire sits at the crossing of company law, which asks who approved the agreement, corporate tax law, which caps the deductible interest three times over, and withholding law, which taxes the interest at source before any treaty relief. This guide explains, for a foreign shareholder running a French company from abroad, how to paper a shareholder advance so it survives an audit, which related-party approvals the loan needs, when the account can be blocked to reassure a bank, how French law caps deductible interest, when the excess is reclassified as a dividend, what France withholds on interest paid abroad, when the European exemption or a treaty removes the levy, and how to get the principal and the lawful interest back without boarding a plane. Every key rule below is anchored to the exact statutory text you can verify yourself on Légifrance, with the official wording quoted.

I. Lend to your French company from abroad without creating a defective loan

A shareholder advance (the compte courant d’associé, literally the shareholder’s current account with the company, the ledger account recording sums a shareholder leaves at or places at the company’s disposal on top of share capital) looks informal and is legally demanding. French law treats it as an agreement between the company and an insider, which means it must be written, priced, approved by the disinterested decision-makers, and repayable on terms the file actually states. Foreign owners who wire money with a bare bank reference create a loan the auditor cannot qualify, the bank cannot count as quasi-equity, and the tax administration can reprice at will. The paperwork below is what turns a wire into a loan.

A. Write the agreement and get the insider approval: reports, votes and blocked accounts

Start with a signed loan agreement before or at the same time as the wire, not months later when the auditor asks. The agreement states the amount in euros, the currency and foreign-exchange risk if the funds travel from a non-euro account, the interest rate and its reference index, the maturity or notice period for repayment, the subordination or blocking terms if any, and the governing law. Date each advance separately: founders often make three or four wires in a year and book a single lump sum, which makes it impossible to prove the rate and term of each drawing if the administration challenges one of them. Keep the SWIFT messages and the foreign bank statements showing the origin of the funds, because the French bank receiving the money must identify the source under its anti-money-laundering duties, and a transfer from a personal account with no contract routinely triggers a request for explanations that freezes the funds for weeks.

The agreement is then a related-party transaction (the convention réglementée, an agreement between the company and one of its directors or shareholders subject to a special approval procedure), and the approval route depends on the company form. In a SARL (the société à responsabilité limitée, the limited liability company with intuitu personae features many small businesses use), article L. 223-19 of the Code de commerce (French Commercial Code) provides that the manager or, where one exists, the statutory auditor “présente à l’assemblée ou joint aux documents communiqués aux associés en cas de consultation écrite, un rapport sur les conventions intervenues directement ou par personnes interposées entre la société et l’un de ses gérants ou associés”, that “L’assemblée statue sur ce rapport”, and that “Le gérant ou l’associé intéressé ne peut prendre part au vote et ses parts ne sont pas prises en compte pour le calcul du quorum et de la majorité.” In practice, the foreign shareholder who is also manager does not vote on his own loan: the other shareholders approve it on the basis of a report, and the interested party’s shares are excluded from quorum and majority. Where there is no statutory auditor (the commissaire aux comptes, the independent auditor mandatory above certain thresholds), agreements signed by a manager who is not a shareholder need prior meeting approval. File the report and the resolution with the annual papers: an unapproved insider loan is not void by that fact alone in a SARL, but it can ground the manager’s liability if it harms the company, and it hands the tax administration a ready argument that the advance was never a genuine loan.

In a joint-stock company such as the SAS (the société par actions simplifiée, the flexible company most foreign founders choose, compared with the other vehicles in our guide on choosing between a SAS, a SARL, a branch and a subsidiary in France), the stricter prior-authorisation procedure applies by reference to the rules for public limited companies. Article L. 225-38 of the Code de commerce requires that “Toute convention intervenant directement ou par personne interposée entre la société et son directeur général, l’un de ses directeurs généraux délégués, l’un de ses administrateurs, l’un de ses actionnaires disposant d’une fraction des droits de vote supérieure à 10 % ou, s’il s’agit d’une société actionnaire, la société la contrôlant au sens de l’article L. 233-3 , doit être soumise à l’autorisation préalable du conseil d’administration.” A foreign parent holding more than 10% of the votes, or the controlling company of a corporate shareholder, therefore needs the board’s prior authorisation (or the equivalent collegial decision the SAS articles designate), followed by the auditors’ special report and the shareholders’ vote with the interested party excluded. SAS articles often designate which body authorises, so read them before signing: an authorisation given by the wrong body is as fragile as no authorisation at all. The remainder of the article extends the same prior-authorisation requirement to agreements in which one of these persons is indirectly interested and to agreements with related companies. Note the boundary with day-to-day business: agreements on current operations concluded on normal terms escape the procedure, but a shareholder loan bearing interest above market rate or with unusual subordination is never current business on normal terms, so do not rely on the exception for it.

Consider blocking the account (the compte courant bloqué, a shareholder advance contractually frozen for a fixed period, often several years) when a bank, a landlord or a key supplier asks for stronger equity. A blocked advance stays repayable only at the end of the freeze, which lets the company’s balance sheet present it as quasi-equity and reassures third parties without a formal capital increase (the augmentation de capital, with its notarial or registry costs and publication). The freeze must be written, dated and signed by both sides, with the release date and the interest regime during the freeze stated expressly. Do not block verbally and do not backdate: auditors and courts treat an undated blocking letter produced during litigation as no evidence at all, and a founder living abroad who cannot show when he signed what loses the first evidential battle.

B. Operate the advance from abroad: wires, currency, filings and the Paris circuit

Run each movement through the French company’s bank account with a reference that names the agreement and the drawing number, for example advance number 3 under the loan agreement of 14 January. Interest should be computed and credited at the agreed dates, with a yearly statement sent to the lender and booked in both companies’ accounts where the lender is a foreign company. Where the lender is an individual, French law requires the capital to be fully paid up before any interest deduction, a condition examined in the tax section below, so check the Kbis (the official company identity extract issued by the commercial court registry, the greffe) and the capital accounts before promising interest. Never repay yourself by netting the advance against a dividend that has not been voted, or by taking company cash while travelling in France: commingling turns the clearest loan into a confused account the administration reclassifies at its convenience.

For companies registered in Paris and the Île-de-France region, three local specifics matter. First, the Paris commercial court registry (the greffe du tribunal de commerce de Paris) keeps the company file and issues the Kbis your foreign bank and your home tax authority will ask for; the annual accounts showing the shareholder debt must be filed there electronically via the one-stop shop (the guichet unique, the single INPI-run portal for business formalities) within one month after the meeting, two months online. Accounts that hide a large insider debt invite questions from every reader. Second, the company tax office (the service des impôts des entreprises, known as SIE, the local branch of the French tax administration) competent for deduction and withholding questions is the SIE of the registered office (the siège social), so a Paris-registered company corresponds with a Paris SIE, in French, with spring response times that favour early, complete filings over fragmentary ones. Third, Paris banks apply the strictest source-of-funds checks on incoming foreign wires: send the signed agreement to the relationship manager before wiring, not after the compliance freeze, and keep a French-speaking contact able to answer within days. These three reflexes cost nothing and prevent the two classic blockages, frozen wires and unprocessable filings, that strand foreign founders each quarter.

II. Price the interest correctly, keep the deduction and recover the withholding

French tax law taxes the interest on your advance three times in succession: first it caps what the French company may deduct, then it reclassifies any excess as a dividend, then it withholds tax on the interest paid to you abroad before any treaty relief. Each stage has its own ceiling and its own proof, and founders who negotiate only the headline rate with themselves lose at all three. Work through the three ceilings in order, because the deductible rate, the arm’s-length rate and the treaty rate are three different numbers that rarely coincide.

A. Three ceilings on deductible interest and the dividend trap for the excess

The first ceiling applies to every shareholder advance whatever the company form. Article 39 of the Code général des impôts (CGI, the French Tax Code) allows deduction of “Les intérêts servis aux associés à raison des sommes qu’ils laissent ou mettent à la disposition de la société, en sus de leur part du capital, quelle que soit la forme de la société, dans la limite de ceux calculés à un taux égal à la moyenne annuelle des taux effectifs moyens pratiqués par les établissements de crédit et les sociétés de financement pour des prêts à taux variable aux entreprises, d’une durée initiale supérieure à deux ans.” Interest paid to shareholders on sums left at the company’s disposal is therefore deductible only up to interest computed at a statutory reference rate (the average annual rate banks charge firms for long variable-rate loans, published quarterly by the Banque de France), and the same article adds that “Cette déduction est subordonnée à la condition que le capital ait été entièrement libéré”, meaning the company’s share capital must be fully paid up before a single euro of interest is deductible. A founder who incorporated with partly unpaid capital and immediately lent at 6% while the reference rate stands near 5% loses the deduction twice: the capital condition fails and the rate exceeds the cap. Fully release the capital first, then set the rate at or below the reference rate in force at the drawing date, and diary the quarterly publication: the ceiling moves with the market and last year’s compliant rate can become this year’s excess.

The second ceiling targets advances from related companies. Article 212 of the Code général des impôts provides that interest on sums left at an enterprise’s disposal by an associated enterprise or a related party is deductible “Dans la limite de ceux calculés d’après le taux prévu au premier alinéa du 3° du 1 du même article 39 ou, s’ils sont supérieurs, d’après le taux que cette entreprise emprunteuse aurait pu obtenir d’établissements ou d’organismes financiers indépendants dans des conditions analogues”. A French subsidiary borrowing from its foreign parent may therefore deduct interest up to the article 39 reference rate, or up to the higher rate it proves it could have obtained from an independent bank in similar conditions. The second branch is an opportunity and a burden: a subsidiary with solid collateral can defend a rate above the reference average, but only with contemporaneous evidence such as refused or granted bank term sheets for comparable loans, not with an ex post affirmation. Assemble that evidence when the loan is signed, because reconstructing a market rate two years later during an audit convinces nobody. Note that indexation clauses attached to shareholder advances are treated as interest: the same article 39 states that “les produits des clauses d’indexation afférentes aux sommes mises ou laissées à la disposition d’une société par ses associés ou ses actionnaires sont assimilés à des intérêts”, so a clever clause linking repayment to an index does not escape the ceilings. The same article 39 of the Code général des impôts states: “A compter du 1er janvier 1983, les produits des clauses d’indexation afférentes aux sommes mises ou laissées à la disposition d’une société par ses associés ou ses actionnaires sont assimilés à des intérêts.”

The third ceiling is general and catches large borrowings regardless of the lender. Article 212 bis of the Code général des impôts provides that net financial charges borne by a company outside a tax-consolidated group are deductible “dans la limite du plus élevé des deux montants suivants : 1° Trois millions d’euros ; 2° 30 % de son résultat déterminé dans les conditions du II.” Net interest above 3 million euros or 30% of the adjusted result (a tax EBITDA defined by the same article) is partly non-deductible with carry-forward mechanics. Most small foreign-owned companies stay below these thresholds, but a French subsidiary carrying a large acquisition loan from its foreign parent plus shareholder advances can cross them sooner than expected: model the 30% test before stacking debt, because interest disallowed here is lost for the year even if every other ceiling was respected.

Interest that breaches the ceilings does not simply vanish: the excess can be reclassified as a distribution. Article 109 of the Code général des impôts treats as distributed income “Tous les bénéfices ou produits qui ne sont pas mis en réserve ou incorporés au capital” and “Toutes les sommes ou valeurs mises à la disposition des associés, actionnaires ou porteurs de parts et non prélevées sur les bénéfices.” Excess interest made available to a shareholder can therefore be taxed as a dividend in the shareholder’s hands, with the dividend withholding analysed below instead of the interest regime, and without the company’s deduction. The practical consequence is severe for a foreign lender: the payment suffers the higher dividend levy while the French company loses the charge. This is why the rate clause deserves more negotiation time than the principal amount: a point of rate above the ceiling converts deductible interest into non-deductible deemed dividends.

B. Withholding on interest paid abroad, European exemption and treaty reclaim

Interest actually and lawfully paid to a lender who lives abroad suffers French withholding at source. Article 119 bis of the Code général des impôts brings investment income paid to persons with neither tax domicile nor seat in France within a levy “dont le taux est fixé par l’article 187”, and article 187 of the Code général des impôts sets the applicable rates for interest, currently 15% for the portfolio interest categories it lists and the standard corporate rate for the remainder, with a 75% rate for payments routed through non-cooperative States absent proof of non-fraudulent purpose. The French company deducts the levy, pays it to the Treasury and wires the net interest with a slip (the relevé de retenue) the foreign lender keeps for the reclaim file. Repayment of the principal itself is never subject to withholding: only the interest is taxed, so keep principal and interest on separate lines of every slip and every transfer reference.

Two reliefs can remove or reduce the levy. Within Europe, the interest-and-royalties exemption applies: article 119 quater of the Code général des impôts states that “La retenue à la source prévue au 1 de l’article 119 bis” is not applicable to interest, defined as income from claims of any kind excluding late-payment penalties, paid by a French company subject to corporate tax to an associated company of another Member State meeting the directive conditions, including a minimum holding (in practice 25% of capital or voting rights held continuously for two years), liability to corporate tax without exemption, and beneficial ownership. A German or Spanish parent holding 100% of its French subsidiary for more than two years and liable to tax at home typically collects the interest gross, provided it delivers the qualifying certificate to the French payer before payment. Test the holding percentage and duration first, exactly as for dividends: most failed exemption files collapse on these two points.

Outside the exemption, the tax treaty between France and the lender’s residence State usually caps the interest levy, very often at 0% for interest beneficially owned by a resident of the treaty partner, with specific conditions per treaty that must be read article by article. The standard path is levy at the domestic rate then reclaim (the demande de remboursement) of the excess on the French forms 5000 (general residence claim, the formulaire 5000) and 5001 (computation schedule, the formulaire 5001) published by the national tax authority (the Direction générale des finances publiques, via impots.gouv.fr), with the foreign tax authority certifying residence and beneficial ownership at the payment date. The file has four pieces: the signed loan agreement with its rate and term, the interest computation and the withholding slip showing gross interest and levy deducted, the certified forms 5000 and 5001 with matching names, amounts and dates, and a bank identity statement in the claimant’s name for the refund. Send it to the office designated on the forms by registered mail with acknowledgement (the envoi en recommandé avec accusé de réception), calendar the domestic reclaim limitation period from the payment date, and require exact matching across documents: a transliterated company name or a converted currency figure replacing the euro amount returns the file for months. Where holding chains pass through intermediate companies, document substance at the claimant level, premises, staff or genuine management, board minutes recording the loan granted, and accounts booking it, because conduit structures with no activity beyond receiving and passing on interest risk refusal of both the European exemption and the treaty rate.

Getting the principal back is a company-law matter, not a tax event, provided the file is clean: at maturity or after the notice period, the company repays by transfer with a reference naming the agreement and the drawing, books the discharge, and keeps the lender’s receipt. If the company cannot repay because cash is short, renegotiate in writing before the maturity date, extend expressly, and re-run the related-party approval where the extension is material: a silently evergreen advance that is never called looks like hidden capital to an auditor and like an available asset to a creditor. If the company refuses to repay a matured advance, the lender sues for payment before the commercial court (the tribunal de commerce) with the agreement, the wire proofs, the account statements and the formal demand (the mise en demeure) as exhibits, and may seek interim payment (the référé-provision, the fast-track order for an evidently due debt) where the debt is not seriously contestable. Each step runs in French with strict time limits, so mandate a French-speaking representative at the first sign of refusal rather than after the limitation period has started to bite.

Conclusion

A shareholder advance from abroad succeeds when the loan file and the tax file tell the same story: a signed agreement with amount, rate, term and blocking conditions approved through article L. 223-19 in a SARL or article L. 225-38 in a SAS, capital fully released before any interest promise, a rate set within the article 39 reference ceiling and, for related-party loans, defended with bank-comparable evidence under article 212 while watching the article 212 bis 30% limit, excess interest kept clear of the article 109 dividend trap, withholding computed under articles 119 bis and 187, the article 119 quater European exemption tested before any treaty discussion, and a reclaim file whose agreement, slips, certified forms and bank details match to the euro and to the day. Lend through this sequence, keep each document the next step will ask for, and your own money can work in your French company and come home with its lawful interest and no tax left unrecovered.
