A first French VAT return can be missed for a surprisingly ordinary reason: the company has just been incorporated, the foreign founder is still waiting for banking access, the accountant has not received the Kbis, or the first invoice has been issued from a group system that does not yet recognise the French entity. The missed filing is still a tax event. A French company may have to file a return even when it has made no sale, and the answer depends on its VAT regime, the period concerned, the tax due, and the transactions that took place before the omission was discovered.

This guide addresses a narrow but urgent situation: a company incorporated in France by a non-French founder has missed its first CA3, the French VAT return form numbered 3310-CA3. It explains how to identify the correct filing period, distinguish a late return from late payment and from an inaccurate return, reconstruct the input and output VAT, contact the SIE (Service des impôts des entreprises, the business tax office), and create a reliable calendar for the next declarations. It also covers cross-border services, reverse charge entries, VAT credits, evidence, and the position of a foreign director who is managing the company remotely.

The practical objective is not simply to send a form. The company must make the filing identifiable as a correction, pay or claim the correct amount, preserve the supporting documents, and explain any delay in a controlled way. The official rules are found in the French Tax Code, the tax administration’s professional guidance, the guichet unique of the French National Institute of Industrial Property (INPI), and the company’s professional tax account. The following legal framework is a starting point for action, not a substitute for reviewing the company’s actual invoices and contracts.

I. What does a missed first CA3 mean for a newly incorporated French company?

A. Does a new French company have to file a CA3 when it has made no sales?

Incorporation and VAT filing are related but separate questions. The company is created through the French one-stop shop, known as the guichet unique, operated by INPI. Since 1 January 2023, that route is the single channel for business formalities, including the transmission of information to the competent authorities. It is not, however, a substitute for the VAT declarations that must later be sent through the company’s professional tax account. INPI’s official explanation of the business formalities one-stop shop is useful when a founder is trying to understand the registration trail, but the CA3 belongs to the tax administration’s ongoing compliance process.

The first question is the company’s VAT regime. A French company under the real normal VAT regime generally files form 3310-CA3 each month. The filing can be quarterly when the annual VAT payable is below the statutory threshold of €4,000. The exact due date is not safely inferred from the date of incorporation or from the date of the first invoice: it is displayed in the company’s professional tax account and follows the tax administration’s filing calendar. The official impots.gouv.fr VAT guidance confirms the monthly rule and the quarterly option for businesses below that threshold. The official Service-Public declaration page for form 3310-CA3 also identifies the monthly or quarterly declaration under the real normal regime and the electronic filing requirement.

Article 287 of the French Tax Code provides the legal starting point. It states: Tout redevable de la taxe sur la valeur ajoutée identifié conformément aux dispositions combinées des articles 286 ter et 286 ter A est tenu de remettre au service des impôts dont il dépend et dans le délai fixé par arrêté une déclaration conforme au modèle prescrit par l’administration. The obligation is attached to the identified VAT taxpayer, not to the subjective belief that the first period was commercially inactive. The same article describes the monthly filing rule for taxpayers under the real normal regime and provides that a taxpayer whose annual tax payable is below €4,000 may file by calendar quarter. The current text is available in Article 287 of the French Tax Code on Légifrance.

This is why “no sales” does not automatically mean “no return”. A nil return can still be required when the company was registered for French VAT for the period. The return may need to show no output VAT, but it can also contain deductible VAT on incorporation costs, professional fees, software, office expenses, travel, or equipment. A company that files nothing loses the chance to present that position clearly and may delay recovery of a VAT credit. A company that files a zero return while it actually made taxable sales creates a different and more serious problem.

The company should therefore identify four dates before preparing anything:

1. the date on which the French entity became liable or identified for VAT;
2. the beginning and end of the first monthly or quarterly VAT period;
3. the due date shown in the professional tax account for that period; and
4. the date on which the company discovered the missed filing.

Those dates can differ from the Kbis date. The Kbis is the official extract from the French commercial register; it proves registration and identifies the company, but it does not, by itself, determine every VAT filing deadline. The SIREN is the nine-digit national company identification number, while the SIRET identifies an establishment. The VAT number is a separate tax identifier, normally beginning with the country code “FR” and including a two-digit key. A foreign founder should keep all three sets of information separate when corresponding with the SIE.

The company must also examine the tax option made during registration. A French business under the franchise in basis may not charge VAT and may have different filing obligations. A business that opted for VAT, exceeded the relevant limits, carried out certain intra-European transactions, or was placed under a real VAT regime may have filing duties even before its first domestic sale. The answer cannot be established only from the company’s turnover. It requires the tax regime shown in the tax account and the registration or option documents. The firm’s English company-law and business set-up resource can be used as a starting point for the corporate context, while the VAT regime itself must be confirmed with the tax administration.

A foreign-owned company can also have reporting lines without ordinary French sales. For example, a service bought from a supplier established outside France may be subject to the reverse charge. A service supplied to a business customer in another European Union Member State may require a different declaration or a statement of the customer’s VAT number. Goods imported into France can create import VAT and customs evidence. The absence of a French customer is therefore not proof that the CA3 is empty.

The official VAT overview on impots.gouv.fr explains the declaration channels, while the company’s professional account provides the operational due date and the available form. A founder should save a PDF or screenshot of that account information, the VAT regime notice, and the filing acknowledgement. If access is missing, that access problem should be documented separately; it should not be treated as proof that no filing was due.

B. What is the legal risk: late filing, late payment or an inaccurate return?

A missed first CA3 can produce several different exposures. They should not be blended together because the correction, evidence, and request to the tax office will differ.

First, there is late filing. The return was not transmitted by the deadline, whether it should have been a nil return, a return showing deductible VAT, or a return showing VAT payable. Article 1728 of the French Tax Code sets out the late-declaration increase. Its opening rule is: 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 : The article then provides the familiar 10% level in the ordinary case, a higher level after a formal notice is ignored, and an 80% level for an occult activity situation. The current provision is Article 1728 of the French Tax Code on Légifrance.

Second, there is late payment. The company may have filed a return but not paid the declared balance, or it may now discover that its late return produces VAT to pay. Article 1727 states: 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. The article’s rate is expressed as 0.20% per month for the relevant period. This interest is conceptually different from a punitive increase. The Conseil d’État explained in a VAT case that the interest is not a sanction but compensation for the Treasury’s loss of use of the money: les intérêts de retard prévus par le premier alinéa de l’article 1727 du code général des impôts s’appliquent indépendamment de toute appréciation portée par l’administration fiscale sur le comportement du contribuable et n’ont, dès lors, pas le caractère d’une sanction mais d’une réparation du préjudice subi par le Trésor. That decision is Conseil d’État, 8th and 3rd chambers, 27 April 2009, no. 308444, available on Légifrance. The applicable statutory text is Article 1727 of the French Tax Code.

Third, there is the separate 5% payment increase in Article 1731. It begins: Donne lieu à l’application d’une majoration de 5 % tout retard dans le paiement. The provision also contains an important qualification where a late declaration is filed with full payment. The exact result depends on what was filed, what was paid, and whether the tax was assessed through a return or another procedure. The company should not assume that every late CA3 automatically attracts every possible percentage. It should calculate the declared tax, the payment date, the filing date, and any notice from the administration against the wording of Article 1731 of the French Tax Code.

Fourth, there is an inaccurate return. A company might file a nil CA3 even though it charged VAT, omit reverse-charge lines, claim input VAT without a compliant invoice, put the wrong period on a correction, or report a VAT credit without evidence. That issue is different from simply filing late. A correction should make the period and the rectified nature of the filing clear. In Conseil d’État, 9th Chamber, 9 July 1984, no. 37467, the court stated that a taxpayer may repair an omission or insufficiency even during an audit, but only under conditions including that the declaration be explicitly corrective, identify the period retrospectively, and be accompanied by payment of the tax due: si un redevable a la faculté de réparer une omission ou une insuffisance de déclaration de ses opérations imposables, et ce, même en cours de vérification de sa comptabilité, c’est, toutefois, à la condition que la déclaration apparaisse explicitement comme rectificative, précise la période à laquelle elle se rapporte rétroactivement et soit accompagnée du paiement des droits dus ; The official decision is Conseil d’État no. 37467 on Légifrance.

That decision does not mean that a company can erase a late filing by adding the word “rectificative”. It means that the administration must be able to understand what period and what taxable operations the correction concerns. A first CA3 filed after the deadline should be labelled and explained in a way that prevents it from being mistaken for a new period or a duplicate return.

The “right to make a mistake” also has limits. The tax administration’s official right-to-correct guidance distinguishes a good-faith inaccuracy or omission corrected promptly from a late filing or late payment. A spontaneous correction may reduce late-payment interest in qualifying circumstances, but it does not give a company a general exemption from filing deadlines. The administration will look at the conduct, the completeness of the correction, and whether the company acted before a formal control or notice.

The Conseil d’État’s decision of 24 February 2021, no. 434129, shows why the timeline matters. In examining repeated omissions, the court referred to whether les déclarations rectificatives auraient été faites spontanément avant toute procédure de contrôle. The decision, available as Conseil d’État no. 434129 on Légifrance, does not turn every voluntary correction into a defence. It illustrates the importance of acting before a control, keeping a dated record of discovery, and making the correction complete rather than sending an unexplained partial payment.

Finally, the company should distinguish output VAT from input VAT. Output VAT is the VAT charged or due on the company’s taxable sales. Input VAT is VAT charged to the company on eligible purchases. Article 271 provides that VAT which has burdened the price of a taxable operation may be deductible, subject to the statutory conditions. The company’s right to deduct can depend on the chargeability date, the invoice, the nature of the expense, and the use of the expense for taxable business. The text of Article 271 of the French Tax Code should be read with the invoice and accounting records, not used as a shortcut for claiming every start-up cost.

The immediate risk assessment should therefore answer these questions:

• Was a CA3 legally due for the period?
• Was the return nil, payable, or in credit?
• Did the company issue invoices, receive payments, or perform cross-border services?
• Was input VAT claimed on invoices that satisfy the deduction rules?
• Has the SIE sent a notice, reminder, formal notice, or assessment?
• Has the company already paid all or part of the VAT?

Only after those questions are answered can the foreign founder choose between an ordinary late return, a corrective return, a payment with an explanation, or a more formal response to the tax office.

II. How can a foreign founder regularise the first CA3 and prevent a repeat?

A. What should the company file, pay and document now?

The safest first action is to freeze the facts for the missed period. Do not begin by guessing a VAT amount from the bank balance. Export the general ledger, sales ledger, purchase ledger, bank statements, issued invoices, supplier invoices, credit notes, import documents, and contracts that show where customers and suppliers are established. Mark each document with the relevant VAT treatment and the date on which the tax became chargeable or deductible. A foreign group should separate the French company’s transactions from those of the parent, even where one group bank account or enterprise resource planning system was used temporarily.

Next, obtain the official filing status. The founder or authorised accountant should log into the company’s professional tax account, identify the missing CA3, and save the due date, filing period, tax regime, notices, and payment instructions. If the account does not display the expected declaration, the company should contact the SIE using the tax account’s secure messaging or the contact details shown for the company. The message should state the legal name, SIREN, VAT number if available, period, date of discovery, and the precise access or filing problem. A generic message such as “we forgot our VAT” does not give the office enough information to direct the correction.

The form should then be prepared for the correct period. If the company has made no taxable transaction and has no deductible input VAT to claim, the return may be nil. If it has deductible VAT, the credit should be supported by invoices and accounting entries. If VAT is due, the return should report the taxable base and the VAT by the applicable categories, and payment should be initiated through the approved electronic channel. The declaration and the payment should identify the same period and the same company. A payment without a return does not generally replace the filing; a return without payment does not settle a balance due.

For a foreign founder, cross-border entries need special care. Article 283 of the French Tax Code sets the general rule that VAT is paid by the persons carrying out taxable operations and includes reverse-charge mechanisms for certain transactions by suppliers not established in France. The statute states: La taxe sur la valeur ajoutée doit être acquittée par les personnes qui réalisent les opérations imposables. It also contains rules under which the recipient reports VAT for qualifying supplies by a non-established supplier. Read the current Article 283 on Légifrance against the supplier’s country, customer status, place-of-supply rule, and contract.

A French company receiving an invoice from its foreign parent may have to assess whether the charge is a service, a transfer of goods, a financing transaction, a capital contribution, or a reimbursement. The accounting label “intercompany” is not a VAT analysis. A service bought from a United Kingdom, United States, or other non-French supplier can have a reverse-charge consequence, while an equity contribution does not become a taxable service merely because money moved between group accounts. The company should preserve the agreement, invoice, evidence of performance, VAT numbers, and payment trail.

Similarly, a French company supplying a business customer in another European Union Member State may need to check the customer’s VAT number, the place of supply, the invoice wording, and the separate European reporting obligations. The French tax administration’s professional VAT guidance describes the interaction between the CA3, the reverse charge, and the European services declaration. The DES (déclaration européenne de services) is not the CA3, and one filing cannot be used as a substitute for the other. The relevant procedure should be confirmed through the company’s professional tax account and the official instructions applicable to the transaction.

Invoicing evidence is equally important. Article 289 of the French Tax Code requires a taxable person to ensure that an invoice is issued for operations within its scope. The opening text states: Tout assujetti est tenu de s’assurer qu’une facture est émise. A compliant invoice normally supports the amount and date of output VAT, while a supplier invoice supports input VAT only when the statutory conditions are met. The current source is Article 289 on Légifrance.

Where a VAT balance is payable, calculate the principal first. Then identify any interest or increase shown by the tax account and explain the company’s voluntary correction. The founder should not promise the SIE that no penalties will apply. The request can instead ask the office to consider the company’s good faith, its prompt spontaneous correction, the absence of concealment, the quality of the records, and any payment already made. If cash flow prevents immediate full payment, ask promptly about an agreed payment arrangement and provide a realistic schedule. A payment proposal should not be used to delay filing.

Where the return produces a VAT credit, verify whether the company wants to carry the credit forward or request a refund. A refund application requires more than a spreadsheet. The administration may ask for invoices, proof of payment, contracts, business activity, import documents, or explanations for start-up expenditure. The company should check whether a refund threshold, specific form, or additional supporting document applies to its situation. The existence of a credit does not automatically cancel the filing obligation or the consequences of a late return.

The correction package should contain a short factual letter, the filed CA3 acknowledgement, the payment receipt or refund request, and a document index. A useful letter has this order:

1. identify the company, SIREN, VAT number, and the period;
2. state that the attached declaration is a late or corrective CA3 for that period;
3. explain the actual cause of the omission without inventing a technical excuse;
4. state the output VAT, input VAT, net amount, payment, or credit;
5. list the principal supporting documents;
6. confirm the steps taken to prevent a repeat; and
7. ask the SIE to confirm any remaining balance, increase, interest, or administrative step.

The letter should use the words “late declaration” or “corrective declaration” accurately. A document called “correction” that does not state the period, or that silently changes a prior amount, can create confusion. If a prior CA3 was actually filed but contained an error, the company should follow the available correction process rather than filing a second ordinary return for the same period without explanation.

In Conseil d’État, 18 June 2024, no. 471220, the court considered the time limit for correcting an omission concerning deductible VAT. It held: Il résulte des dispositions citées au point 2 que le délai imparti pour réparer une omission de déclaration de la taxe sur la valeur ajoutée déductible court à compter de la date d’exigibilité de la taxe chez le redevable et expire le 31 décembre de la deuxième année suivant la date à laquelle la déclaration devait être effectuée. The decision adds that, where deductible tax was declared on time but omitted from the return, the correction period expires on 31 December of the second year following the original filing deadline. This is Conseil d’État, 9th Chamber, no. 471220 on Légifrance. The ruling concerns a specific deduction issue and should not be treated as a universal extension of every CA3 deadline.

The final part of the immediate package is an internal evidence file. Keep the original source documents, the calculations, the version of the return, the acknowledgement, the secure messages, and the payment confirmation in a folder named with the period. Record who approved the filing. A foreign director may later need to show the board, the parent company, a bank, or the French tax office how the number was obtained. A clear audit trail is valuable even where the tax amount is zero.

B. How should the company deal with the SIE and the next deadlines?

The SIE is the company’s business tax office. Its identity can change with the registered office, and it should be taken from the professional tax account or official correspondence rather than copied from an old group file. Contact should normally be made through the secure messaging service of the professional account, because that channel links the message to the taxpayer’s record. The company should retain the sending date, attachments, acknowledgement, and any response. A phone call can be useful for orientation, but it should be followed by a written summary.

The message should be concise enough to be processed and detailed enough to avoid a second request for basic information. An English-speaking founder can prepare the factual explanation in English for internal approval, but the message to a French tax office should be checked for accurate French tax terminology. The SIE may reply in French and may use terms such as mise en demeure (formal notice), majoration (increase), intérêts de retard (late-payment interest), crédit de TVA (VAT credit), or régularisation (regularisation). Those terms describe different steps and should not be translated loosely in board minutes.

If the SIE has already issued a formal notice, the response deadline becomes central. The company should not send a routine apology while ignoring the date stated in the notice. It should identify whether the notice concerns failure to file, a demand for payment, a proposed assessment, missing evidence, or a wider control. The response should address each requested item and attach the filing proof. A formal notice can change the level of the late-declaration increase under Article 1728, so the timeline must be reviewed before the company sends an incomplete response.

Where the SIE does not respond immediately, the company should still file through the normal electronic route and retain the acknowledgement. It should not wait for a telephone appointment before submitting a return that is already due. If the professional account or electronic form genuinely prevents filing, take dated screenshots, record the error message, contact the administration, and ask how the return should be transmitted. The evidence of an access incident can support the explanation, but it does not automatically determine the legal outcome.

The company should then build a calendar around the actual regime. Put the monthly or quarterly CA3 deadline in the shared calendar of the French company, the foreign founder, the accountant, and a backup administrator. Add reminders for document collection, review, filing, payment, and acknowledgement. The filing reminder should be earlier than the legal due date. For a business managed across time zones, use the time zone displayed by the French professional account and assign an owner in France or in a compatible working day.

The calendar should include more than the CA3:

• the European services declaration where cross-border B2B services require it;
• import VAT and customs evidence when goods enter France;
• annual accounts and corporate tax deadlines;
• CFE (cotisation foncière des entreprises, the local business property contribution) notices and declarations;
• payroll and social declarations if the company hires staff; and
• the annual review of VAT regime, options, activities, and registered office.

A founder can use the firm’s existing English guide to VAT registration for a foreign company in France to cross-check the registration stage, and the separate guide on a French VAT number not being activated before the first invoice when the difficulty is an identifier rather than a missed return. Those articles address neighbouring problems; neither removes the need to file the CA3 for a period in which the company was required to declare.

Banking arrangements deserve a separate control. A French corporate bank account is not necessarily required to file a return, but it can affect the ability to pay the declared VAT and to evidence the company’s funds. The person who can approve a bank transfer may be different from the person who can access the tax account. The foreign founder should therefore test both permissions before the next deadline. A pending Kbis update, a change of legal representative, or a bank compliance review should be escalated before the VAT due date.

Changes in the company’s registered office, director, activity, or intra-group model should be reflected in the tax record. A registered office provider may forward mail slowly; the company should not rely on a physical letter alone when the professional account contains an electronic notice. A foreign director who delegates accounting should receive a monthly compliance report containing the CA3 period, filing date, amount, payment date, acknowledgement, and exceptions. Delegation transfers a task, not the company’s need to supervise the result.

Late payment should be treated as a cash-management issue as well as a tax issue. Maintain a reserve for output VAT collected from customers. Do not treat collected VAT as operating revenue. When the first CA3 is payable, compare the VAT ledger with the bank balance before approving distributions, intercompany transfers, or large supplier payments. If a group treasury team sweeps funds out of the French company, its policy should leave enough cash for taxes and payroll. A shareholder loan or capital contribution may solve liquidity, but its corporate and tax documentation must be reviewed separately.

If the company had no activity, do not let that fact become an excuse for silence. File the required nil return, retain evidence of the inactive status, and keep the VAT registration under review. If the company ceased its French activity, a cessation or deregistration process may be required. Closing a bank account or abandoning a registered office does not itself close the VAT file. The SIE should receive the relevant formal information, and the company should keep proof of the effective date.

The company should also be careful with historical corrections. If an omitted input VAT amount is discovered, Article 271 and the applicable correction period must be checked. The Conseil d’État’s no. 471220 decision shows that the right to repair a deduction omission is time-limited. If output VAT was omitted, the no. 37467 decision reinforces the need for an explicit period-specific corrective declaration accompanied by payment where tax is due. If omissions were repeated or control has begun, the no. 434129 decision is a reminder that voluntary conduct and timing may matter to the assessment of the case.

French tax administration guidance also recognises a good-faith path for correcting some errors. The official right-to-correct page explains that the right does not cover every late declaration or late payment and that the taxpayer must act within the relevant procedural framework. A founder should ask for the legal basis of any amount shown by the tax office, compare it with the filed return and payment, and challenge a calculation only with a documented reconciliation. A general request for “penalty cancellation” without a factual chronology is weaker than a precise request tied to a spontaneous correction and complete payment.

The VAT file should be reviewed quarterly even where filings are monthly. Check the customer VAT numbers, supplier locations, reverse-charge codes, credit notes, imports, fixed assets, and intercompany charges. Reconcile the VAT control account with the CA3. Confirm that the accounting software maps French VAT rates and exemptions correctly. Ask whether the company’s service is in scope of French VAT, whether a customer is a taxable person, and where the service is deemed supplied. The aim is to detect a classification error before it becomes a second late return.

For companies using an external accountant, the engagement letter should specify who is responsible for obtaining tax-account access, preparing the CA3, approving the filing, initiating payment, and sending the acknowledgement to the director. The company should have a replacement process if the accountant is unavailable. A foreign founder should not discover at year-end that “VAT handled” meant only bookkeeping entries and not electronic filing. A monthly evidence pack creates a simple control without requiring the founder to master every French form.

The official sources should remain the reference point for the live calendar. Tax rules and electronic procedures can change, and the dates shown in the company’s professional account take priority for the specific taxpayer. The Service-Public CA3 page, the tax administration VAT page, and the company’s account should be checked together. INPI material helps with the corporate formalities trail, but it does not replace the tax account or the SIE’s instructions.

A final control should take place after regularisation: verify that the return is recorded, the payment is matched, the credit appears in the correct period, the next declaration is visible, and no unresolved notice remains. Save the public or tax-account acknowledgement and update the board or parent company. If the first missed CA3 was caused by a process failure, record the corrective action: named owner, earlier reminder, access test, bank authority, accountant confirmation, and backup contact. This turns a one-off emergency into a compliance system.

Conclusion

A missed first CA3 is not resolved by asking whether the company had made its first sale. The decisive questions are whether the company was required to declare for the period, which VAT regime applied, what output and input VAT arose, and whether the return, payment, and evidence now match. A foreign founder should establish the period and deadline, reconstruct the transactions, file the correct nil, payable, or credit return, pay the balance or document the credit, and contact the SIE through a traceable channel.

The legal consequences may involve a late-declaration increase, late-payment interest, a payment increase, or a dispute about the accuracy and timing of a correction. Those consequences are assessed under separate provisions. An explicit period-specific corrective return, prompt voluntary action, complete supporting evidence, and a realistic payment plan give the company a coherent position. They do not guarantee that every charge will be waived. The next CA3 should already be assigned to a named person, tested in the professional tax account, reconciled to the VAT ledger, and followed by a saved acknowledgement.
