Hiring a consultant abroad is often one of the first genuinely cross-border payments made by a French company. A foreign founder may receive a perfectly ordinary invoice for market research, software implementation, engineering, management support or strategic advice. The invoice may show no French value added tax, the consultant may have performed the work outside France, and the payment may be made from an international bank account. None of those facts, taken alone, answers the French income-tax question. A French payer must first ask whether the payment falls within the French withholding regime for sums paid to a non-resident professional.

The central rule is Article 182 B of the French General Tax Code (Code général des impôts, or CGI). It can require the French company to retain tax from the gross amount and remit it to the French Treasury, subject to the precise classification of the service, the consultant’s tax residence, any permanent establishment, and the applicable tax treaty. The same transaction can also raise a separate French VAT issue. Confusing these two taxes is a common source of defective invoices and incomplete files.

This guide addresses the practical question: how should a foreign-owned French company decide whether it must withhold tax when it pays a consultant abroad, and what should it keep before sending the money? The analysis follows the statutory text, official tax guidance and recent administrative court decisions, with a payment file, calculation method and correction plan.

For the wider legal framework affecting international founders, the firm’s French business law resources for international founders provide the relevant starting point. This article focuses on the specific payment and evidence problem.

I. When must a French company withhold tax on a foreign consultant’s invoice?

A. Which payments fall under Article 182 B of the CGI?

The first question is not where the consultant signed the invoice. It is whether the French company is paying a person or company that is subject to French income tax or French corporate income tax and that does not have a professional establishment in France for the relevant activity. Article 182 B of the CGI is the domestic starting point. Its scope includes sums paid for services supplied or used in France. The operative wording is: Les sommes payées en rémunération des prestations de toute nature fournies ou utilisées en France. The full text of Article 182 B of the CGI should be read before classifying a payment.

A foreign consultant can therefore be within the analysis even when the consultant is incorporated in another country and the individual members of the team never travel to France. A report prepared abroad can be used by a French company for its French activity. A remote software consultant can configure systems used by the French subsidiary. A foreign market analyst can deliver research that directly supports the French company’s sales. The factual connection must be documented rather than assumed from the consultant’s address or the place of the video calls.

The payer is the operational actor. The foreign consultant may be the taxpayer in substance, but the French company may be required to calculate the withholding, reduce the amount paid, file the declaration and transfer the retained amount. This is why a founder should review the tax position before approving the invoice. Negotiating the invoice first and investigating withholding several months later can create a dispute about whether the agreed price was gross or net.

Typical payments that require a structured Article 182 B review include:

• consulting, business strategy, commercial support and market-entry advice supplied to a French company;
• technical, engineering, design, software development, implementation and project-management services;
• research, analysis, training and professional assistance used in France;
• services supplied by a foreign group company to its French subsidiary, including management or administrative services; and
• payments whose label is vague but whose deliverables show that an active service was performed for the French business.

The word “consultant” is not decisive. Tax authorities will look at the contract, invoices, deliverables, correspondence, time records, location of the work, the identity of the beneficiary and the commercial use of the result. A contract called “advisory services” will not become a royalty, dividend or exempt business profit merely because the parties chose a convenient heading. Conversely, a payment for a licence to use protected technology may be a royalty rather than a consultancy fee. The classification changes the treaty article, the evidence and often the withholding result.

Article 182 B also contains specific rules for the taxable base and rates. For an ordinary case, the domestic reference rate is connected to the second paragraph of Article 219 of the CGI. Article 219 of the CGI states: Le taux normal de l’impôt est fixé à 25 %. That does not mean that every foreign invoice automatically produces a 25% final tax. The payment must still be classified, treaty relief must be tested and any special statutory rule must be checked.

Article 182 B also contains a 75% rate for payments to an entity in a state or territory that is non-cooperative for tax purposes, commonly abbreviated as ETNC (État ou territoire non coopératif). The legislation provides a route for addressing real and effective operations, but a founder should not treat an ordinary certificate of incorporation as enough. The country list, the recipient’s status and the proof of genuine activity require a date-specific review.

There are also rules that may reduce the taxable base for a qualifying corporate recipient established in the European Union or European Economic Area. That relief is conditional and is not a general 10% deduction available to every overseas consultant. The French company should obtain the recipient’s legal and tax information before using it. If the file does not establish the conditions, the safer approach is to calculate on the statutory base and obtain advice on any later claim.

Consider a simple illustration. A French SAS, meaning a société par actions simplifiée or simplified joint-stock company, receives a €10,000 gross invoice from a non-resident consultant. If the domestic 25% reference rate applies and no treaty relief is available, the company would retain €2,500, pay €7,500 to the consultant and remit €2,500 to the Treasury. If the contract promises the consultant €10,000 net, the company cannot simply retain €2,500 from that agreed amount without checking the contract. A gross-up at 25% would produce a gross base of €13,333.33, a withholding amount of €3,333.33 and a net payment of €10,000. The arithmetic is easy; the contractual and treaty analysis is not.

The payment date also matters. A company that makes several instalments should examine each payment and maintain a schedule. An advance, milestone payment, reimbursement, final balance and success fee may not have the same factual basis. A single annual invoice can conceal several payment events and several deadlines. The accounts team should record the date on which funds leave the French company’s account, not only the invoice date.

The official tax administration guidance for a French business paying income to non-residents identifies the withholding rules and the payment timetable. It is useful operational guidance, but it does not replace the legal classification of the service or the relevant treaty. The company should retain a copy of the version consulted and note the date of the check in its tax file.

A foreign founder should also separate four transactions that are often described imprecisely as “paying a foreign consultant”:

Transaction	Primary question	File to build
Independent services	Were services supplied or used in France, and does Article 182 B apply?	Contract, deliverables, residence and treaty evidence, payment schedule
Employment	Is the person really an employee of the French company or a foreign employer?	Role, control, place of work, payroll and social-security analysis
Licence or intellectual property	Is the payment a royalty rather than a service fee?	Licence grant, rights used, treaty classification and valuation
Dividend or shareholder distribution	Is the payment made because of ownership rather than performance?	Corporate approval, distributable profit, shareholder and treaty file

The table is not a substitute for reviewing the facts. It is a control against treating every cross-border transfer as a supplier invoice. The first practical decision is to identify what the foreign party actually did and what legal right the French company received.

B. How do withholding tax, VAT and a permanent establishment differ?

Withholding tax and VAT answer different questions. Withholding tax concerns the French taxation of income paid to a non-resident and the French payer’s collection duty. VAT concerns the supply of goods or services, the place of supply and the person liable for VAT. An invoice can correctly show no French VAT and still require an income-tax withholding review. The reverse is also true: a VAT reverse charge does not by itself prove that Article 182 B is due.

For a business-to-business service, abbreviated B2B, Article 259 of the CGI is the key place-of-supply rule. The ordinary rule looks at the customer’s business establishment, fixed establishment or domicile. Read the current Article 259 of the CGI with the specific nature of the service. If the French company is the customer, the service may be located in France for VAT purposes even though the consultant works abroad.

Under the reverse-charge mechanism, the French customer can become liable for French VAT when a non-established supplier provides a service falling within the relevant rule. Article 283 of the CGI sets out the liability of the recipient for certain services supplied by a non-established provider. The foreign consultant may therefore issue an invoice without French VAT, while the French company self-accounts for output and input VAT if its right of deduction permits. That process is separate from any tax retained under Article 182 B.

The invoice and accounting trail must still be correct. Article 289 of the CGI governs invoicing and preservation requirements. A foreign-language invoice can be commercially useful, but the company must be able to explain the transaction, translate or produce supporting documents if requested, and connect the invoice to its VAT return and payment file. “No VAT charged” is not a sufficient annotation. The accounts team should record the reverse-charge basis and the Article 182 B decision separately.

The permanent-establishment question is different again. A PE is a permanent establishment, referred to in French as an établissement stable. It can affect whether the foreign business is regarded as carrying on activity in France, how business profits are taxed and whether the Article 182 B mechanism is appropriate. A consultant who repeatedly operates from the French company’s premises, negotiates contracts for the foreign entity or has a fixed base available to that entity may create facts that go beyond a remote supplier relationship.

In a decision concerning a Luxembourg company, the CAA Nancy, 21 December 2023, No. 21NC02294, examined evidence of management, human resources, invoicing and activity in France. The court referred to une installation fixe d’affaires dans laquelle elle a exercé son activité. The decision is a reminder that a PE is assessed from the actual organisation and not from the absence of a French line on the consultant’s invoice. The official decision is available at CAA Nancy, 21NC02294.

A group payment needs an additional transfer-pricing review. Article 57 of the CGI allows the administration to restore profits indirectly transferred between related enterprises. The current text of Article 57 of the CGI should be read when a French subsidiary pays its foreign parent, a sister company or a common-service centre. The company should be able to show the benefit received, the allocation key, the work performed, the price comparison and the reason the French entity bore the cost. A generic “management fee” invoice with no deliverables creates both withholding and transfer-pricing risk.

Royalty classification can also change the result. In CAA Paris, 12 February 2026, No. 24PA01330, concerning licence payments between companies, the court concluded that the payment était bien passible d’une retenue à la source under the applicable analysis. The case is not a ruling that every software or technology invoice is a royalty. It shows why the contract must identify whether the French company receives advice, a finished work, a right to reproduce, a right to exploit intellectual property or a combination of those items. The official decision is published at CAA Paris, 24PA01330.

Before payment, the finance team should answer these questions in writing:

1. Who is the legal payee, and is the payee an individual, a company, a partnership or a group entity?
2. What exactly is delivered: advice, labour, software, training, a licence, a reimbursement or a shareholder return?
3. Where is the work performed, where is the result used, and which French activity benefits from it?
4. Does the foreign business have people, premises, authority or a fixed base in France?
5. Is the invoice subject to French VAT, a reverse charge, an exemption or a non-taxable rule?
6. What domestic withholding rule applies, and does a current treaty modify the result?

This written classification is particularly important for a foreign founder who has just incorporated in France. The company’s registered address, SIREN number and Kbis extract do not answer the cross-border tax question. They identify the French company; they do not prove that the foreign consultant has no French PE or that the treaty conditions are satisfied.

The company’s broader compliance calendar should record the decision and the due date. The existing French company legal calendar for foreign founders can be used as an internal planning reference, while the specific withholding timetable should be confirmed against the official tax administration guidance and the current form.

II. How should a foreign founder secure the payment and correct a mistake?

A. What treaty and evidence file should be completed before payment?

French domestic law is only the first layer. If the foreign consultant is resident in a country that has a tax treaty with France, the treaty may allocate taxing rights differently. The relevant article depends on the payment: business profits, independent personal services, royalties, employment income and other categories are not interchangeable. A treaty argument based only on the consultant’s nationality, bank account or place of incorporation is incomplete. Tax residence is a legal and factual status for a specified period.

The company should identify the treaty in force on the payment date, the recipient’s treaty residence and the treaty article that corresponds to the service. For ordinary business profits, the analysis often focuses on whether the foreign enterprise has a PE in France, but the exact treaty wording and any protocol must be checked. For a royalty, the royalty article may impose a capped source-state rate. For an individual consultant, the treaty may contain a separate rule for independent services or employment. The label used by the invoice does not choose the treaty article.

The evidence file should be completed before funds leave France. A practical file includes:

Document	Why it matters	Control question
Signed contract and statement of work	Defines the service, deliverables, price, timing and responsibility	Does it describe services rather than hiding a licence or employment relationship?
Current tax-residence certificate	Supports the treaty residence of the actual recipient	Does it cover the payment period and name the legal payee?
Certificate of incorporation and tax number	Identifies a corporate recipient and its legal capacity	Does the payee on the invoice match the contract and bank account?
Permanent-establishment statement	Documents the foreign business’s French presence analysis	Is there a fixed base, dependent agent or French team that contradicts it?
Deliverables and acceptance evidence	Shows the service was real and commercially useful	Can a reviewer link each invoice line to work actually received?
Beneficial-owner and substance information	Supports treaty and anti-abuse analysis where relevant	Is the recipient the person entitled to the income?
Withholding calculation	Shows the gross base, rate, amount retained and net payment	Was the rate selected from a dated legal and treaty review?
VAT note	Separates reverse charge from income-tax withholding	Does the VAT return reconcile to the same invoice?

Do not turn a certificate into a magic document. In CAA Paris, 14 March 2025, No. 24PA02053, the administration challenged a French company’s withholding position for payments to foreign companies. The court restated the domestic rule and held that the payer remained liable. It stated: La société débitrice est redevable de la retenue à la source. The court also rejected the treaty evidence where the documents did not establish the necessary tax position and residence. The official decision, including its exact number, is available at CAA Paris, 24PA02053.

The lesson is procedural. The French company should not ask the consultant for a residence certificate only after an audit notice. It should ask for the certificate at onboarding, set an expiry or annual renewal date, and identify the person responsible for checking the certificate. A certificate that names a parent company while the invoice is issued by a subsidiary does not automatically support the subsidiary’s treaty position. A document in a foreign language may also need an understandable translation and a connection to the French entity’s accounting records.

The contract should deal expressly with the withholding mechanics. It should state whether the price is gross or net of mandatory French withholding; permit the French company to retain and remit amounts required by law; require the consultant to provide current residence and status documents; define how a treaty claim is supported; and explain how the parties exchange a tax certificate or proof of remittance. A net-price clause should be priced with a gross-up model. A gross-price clause should not be silently converted into a net promise by the accounts department.

For an invoice of €20,000, a 25% domestic calculation would produce €5,000 of withholding and €15,000 paid to the consultant. If a treaty reduces the French rate to 10%, the retained amount would be €2,000 and the net payment €18,000, assuming the treaty conditions and documentation are satisfied. If the treaty eliminates source taxation, the file should explain the legal basis rather than simply show a zero in the accounting software. The calculation should identify whether the rate applies to the gross amount, a permitted reduced base or a treaty-defined category.

The payment calendar must also be built into the process. Under Article 1671 A of the CGI, the payer’s withholding is transferred to the Treasury no later than the fifteenth day of the month following the quarter in which the payment is made, subject to the provision’s detailed scope. The related declaration is made on the same timetable. The official Form 2494-SD page provides the declaration form and its current administrative information.

A calendar entry should include the quarter, the payment date, the gross base, the selected rate, the amount retained, the declaration reference, the transfer confirmation and the person who approved the treaty position. A company that pays on the last day of a quarter may have a different deadline from a company that pays on the first day of the next quarter. Recording only the invoice date is not enough.

For an affiliated consultant, add a benefit test and pricing file. The file should show why the French company needed the service, how the work was allocated between group companies, how the price was set, and whether the French company could have purchased the same service from an independent provider. The file should include board or management approval when appropriate. This does not remove withholding; it makes the transaction easier to defend across the withholding, corporate-tax and transfer-pricing questions.

Finally, connect the payment file to the French company’s wider tax records. A foreign company with a French branch, subsidiary or fixed activity may also need a French VAT number, a tax account and payroll or social-security registrations. Those topics should not be folded into one consultant invoice. The company’s formation file, the French VAT registration guidance for foreign companies and the supplier tax file should cross-reference one another without using the same document as proof for unrelated questions.

B. What should the company do if it paid without withholding?

A payment made without withholding is not repaired by deleting the invoice or asking the consultant to issue a new one. The company should preserve the original records and run a structured correction review. The first step is to stop similar payments until the classification is understood. List each payment date, recipient, country, entity, invoice, bank transfer, currency, service description, place of performance, French use and treaty document. This prevents one late discovery from becoming a recurring error across several suppliers.

The second step is to determine whether a withholding was actually due. Re-read the contract and deliverables. Identify whether the service was supplied or used in France. Check whether the consultant had a French PE or whether the French company was in fact receiving a royalty, employment service, dividend or reimbursement. Then identify the treaty article and determine whether the file proves residence, beneficial entitlement and the absence of a French taxing right. If the classification is uncertain, obtain a written tax analysis rather than choosing the result that produces the smallest payment.

The third step is to reconstruct the gross amount. If the invoice stated €10,000 gross and the company paid €10,000, a later 25% withholding claim may be €2,500, subject to the applicable rules. If the contract promised €10,000 net and the company paid €10,000, the company may need to gross up, subject to the contract and the legal position. Reconstruct the calculation in both scenarios and preserve the assumptions. A spreadsheet with an unexplained figure is not an audit file.

The fourth step is to make the required declaration and payment. The company should use the appropriate 2494-SD process, determine the quarter and deadline under Article 1671 A, and transfer the amount to the Treasury. The finance team should contact the relevant SIE, meaning the Service des impôts des entreprises or French Business Tax Service, where the filing or correction route is unclear. The company should record the date of contact, the answer received and any reference number. A payment to the consultant does not satisfy a separate obligation to the Treasury.

Delay can create additional exposure. Article 1731 of the CGI provides for a 5% late-payment increase in the situations covered by its text, including certain payments under Article 1671. Article 1728 of the CGI provides declaration-related increases that can be 10% in an initial late-filing situation, 40% after a formal notice and 80% in the circumstances described by the statute. These figures are not a substitute for calculating the actual penalty, but they show why a company should correct quickly and document the correction.

The company should not simply deduct a new amount from the consultant’s next invoice. That may create a second contractual dispute, an inaccurate accounting entry or a mismatch with the certificate issued to the consultant. The parties should agree how a gross-up, reimbursement, credit or future offset will be documented. The French company remains responsible for its own tax filing even if the commercial contract says that the consultant bears the tax economically.

If the company has already paid the full invoice but later obtains reliable treaty evidence, the file may support a request for relief, refund or correction, depending on the legal route and the tax concerned. The company should not backdate a certificate or create a deliverable after the event. A later document can explain an earlier fact, but it should be dated and described honestly. Keep the original invoice, email chain, contract version, payment proof and the later evidence together.

The recent CAA Paris decision in No. 24PA02053 is particularly relevant to a late correction because it shows the risk of relying on generalized documents. The court looked for evidence that connected the foreign recipient to the treaty requirements. A certificate that says only “the company is foreign” does not establish the absence of French tax liability. A robust file states the recipient’s legal identity, tax residence for the relevant period, nature of the service, location and use of the work, PE position and treaty consequence.

A later review should also test the French company’s tax returns. If the payment was recorded as a deductible expense, the company should verify that the invoice, VAT treatment, withholding, corporate-tax return and transfer-pricing file are consistent. An error in one return may require a linked correction elsewhere. If the foreign consultant is a director, shareholder or related company, the review should include corporate approvals and conflict-of-interest controls. If the consultant’s actual role resembles employment, payroll and social-security risks may be more serious than the withholding calculation.

For future payments, a simple four-gate workflow is effective:

1. Classify: identify the payee, service, rights transferred, place of performance and French use before approving the contract.
2. Evidence: obtain the current residence certificate, legal identity, PE statement, deliverables plan and treaty analysis before the first payment.
3. Calculate: determine the gross base, domestic rate, treaty rate, VAT treatment, net or gross contract price and quarter deadline.
4. Close: file, remit, obtain proof, reconcile the accounts and renew time-sensitive documents before the next payment.

The workflow should be applied to each new foreign consultant and to each material change in scope. A new country, new group entity, new licence, new permanent team member or new payment stream can change the analysis. Keeping a previous approval in the supplier folder is not enough when the facts have changed.

Foreign founders should also avoid two opposite errors. The first is assuming that every foreign invoice triggers a 25% deduction, which can damage a valid commercial relationship and create an unnecessary gross-up. The second is assuming that a foreign address makes French withholding irrelevant, which can leave the French company liable for tax it never retained. The correct result comes from classification, treaty evidence and a dated payment process.

Conclusion

When a French company pays a foreign consultant, the decisive question is not whether the invoice contains French VAT or whether the consultant worked from abroad. The company must identify the service, its French supply or use, the recipient’s French establishment position, the applicable treaty and the evidence available before payment. Article 182 B of the CGI can make the French payer responsible for withholding and remitting tax, while Articles 259 and 283 may create a separate VAT reverse charge.

A defensible file contains the contract, deliverables, residence certificate, legal identity, PE analysis, treaty article, calculation, declaration and remittance proof. If the company has already paid without withholding, it should stop repeat payments, reconstruct the facts and dates, correct the declaration and address any late-payment consequences. The payment should be handled as a tax-controlled process, not as an ordinary overseas bank transfer.

For a foreign-owned French company, that discipline protects both the cash position and the credibility of the wider corporate file. It also gives the founder a clear answer when the bank, accountant, auditor or French tax administration asks why the payment was made, which tax was applied and where the supporting evidence can be found.
