French VAT Filing, Handled Every Month, So a Missed Deadline Never Costs You 40%

What "VAT filing services" actually covers ?

Three things get confused under one label. Pulling them apart matters, because they carry different price tags and different risk.

Registration is the one-time act of getting your French VAT number. Advisory is the strategic work: structuring transactions, recovering input tax, defending positions in an audit. Filing is the recurring operational cycle that runs every month or quarter for as long as you hold the number. This page is about the third one.

A complete French VAT filing service owns the full obligation set, not just the headline CA3:

• CA3 returns (form 3310-CA3): the standard monthly or quarterly return under the régime réel normal, reporting output VAT, input VAT, imports, and the net position

• CA12 returns (form 3517): the annual return under the régime simplifié, with interim instalments, applicable until the regime is abolished (more on that below)

• DES (Déclaration Européenne de Services): the recapitulative statement for intra-Community supplies of services, filed via the customs portal by the 10th working day of the following month

• EMEBI (Enquête Mensuelle Statistique sur les Échanges de Biens Intra-UE, formerly part of the DEB): the monthly statistical survey on intra-EU goods movements, required only for companies notified by the customs administration

• ERTVA (État Récapitulatif TVA): the VAT recapitulative statement for intra-Community goods deliveries, filed via the customs portal

• Import VAT reporting: since the 2022 reverse-charge reform, import VAT is reported and deducted on the same CA3, removing the old cash advance at customs

The annexes are where foreign companies slip most often. The assumption that the CA3 is the only obligation is exactly the gap a customs query exposes two years later.

The deadline that actually applies to you

There is no single national VAT deadline, and the "19th of the month" figure repeated across the web is a simplification that misleads foreign filers.

For companies under the régime réel normal, the monthly CA3 is due on a date set between the 15th and the 24th of the month following the reporting period. The exact date depends on your legal form, your department, and your country of establishment, and it is displayed inside your professional account on impots.gouv.fr. Intra-Community and import operations push the deadline toward the 24th. Do not assume a date. Read it from the portal, or have your filing partner confirm it.

Filing frequency depends on your situation:

• Monthly CA3: the standard for most VAT-registered businesses, including foreign companies with recurring French operations

• Quarterly CA3: available only where annual VAT due is below 4 000 EUR

• Annual CA12: under the régime simplifié, with two instalments during the year (this regime is being abolished, see the 2027 section)

One operational trap catches international treasuries repeatedly. French VAT is paid exclusively by SEPA direct debit, configured through the professional account. An ordinary bank transfer from a foreign account is not accepted. The SEPA mandate has to be live before the first payment is due, and setting it up late is a frequent cause of an otherwise clean return turning into a late-payment penalty.

Penalties: what late or wrong filing actually costs

The French penalty regime is layered, and the layers compound. The figures below sit in articles 1727, 1728, and 1731 of the General Tax Code (the numbering migrates to the CIBS from 1 September 2026, see further down).

• Late filing (article 1728 CGI): 10% of the VAT due where there is no formal reminder, or where you file within 30 days of one; 40% if you have not filed within 30 days of a formal reminder; 80% in cases of undisclosed or concealed activity

• Late payment (article 1731 CGI): a 5% surcharge on the VAT not paid by the due date

• Late-payment interest (article 1727 CGI): 0.20% per month, equivalent to 2.40% per year

• Errors and omissions: 15 EUR per inaccuracy or omission, with a cap per return

• Failure to provide requested information: fixed penalties starting at 1 500 EUR

These are not abstract. For a foreign-owned distributor carrying a six-figure monthly VAT position, a single filing left past the 30-day reminder window pulls in the 40% band and runs into tens of thousands of euros. The economics of outsourcing are blunt: the annual fee is almost always a fraction of one avoidable penalty event. A good-faith first error, properly documented and corrected, often draws only the late-payment interest, which is precisely why a clean process and fast regularisation matter more than the headline rates.

What changes in 2026 and 2027 (and why your existing guide is probably out of date) ?

Three regulatory shifts are reshaping French VAT filing right now. Most English-language sources have not caught up. If you are working from a guide written before 2026, assume it is stale on every point below.

1. Recodification into the CIBS, from 1 September 2026

Ordinance n° 2025-1247 of 17 December 2025 moves the VAT provisions out of the General Tax Code (CGI) and into the new Code des Impositions sur les Biens et Services (CIBS), effective 1 September 2026. This is a recodification à droit constant, meaning the substance of the rules does not change, only their numbering. Article 287 of the CGI, which defines the VAT filing obligations, migrates to the CIBS on that date. References to the old CGI articles remain legally valid through a transition period to 31 December 2027. Source: impots.gouv.fr, regimes of VAT taxation.

Practical impact on filing: none in the short term, but every template, internal procedure, and engagement letter that cites CGI article numbers should be reviewed before the transition ends.

2. Abolition of the simplified regime (CA12), from 1 January 2027

Article 38 of the Loi de Finances for 2025 (Loi n° 2025-127 of 14 February 2025) abolishes the régime simplifié d'imposition (the annual CA12 with instalments) from 1 January 2027, for operations whose VAT becomes chargeable from that date. Companies currently on the simplified regime will move to the régime réel normal with monthly or quarterly CA3 filing, or to the franchise en base exemption where they qualify. The 2026 thresholds for the franchise en base were confirmed unchanged after the proposed single 25 000 EUR threshold from the 2025 Finance Law was dropped. Source: Service-Public Entreprendre, verified February 2026.

If your French entity files annual CA12 returns today, plan the transition to monthly or quarterly CA3 now. The cadence change has cash flow and process implications that should not be discovered in January 2027.

3. E-invoicing and e-reporting, from 1 September 2026

The e-invoicing reform brings mandatory electronic invoicing and e-reporting, phased from 1 September 2026 for large companies and ETI, and 1 September 2027 for SMEs and micro-enterprises. Over time, transaction data flowing from e-invoicing will feed the tax authority's view of your VAT position. France has signalled that pre-filled VAT returns are unlikely before 2030, so for now the CA3 still has to be prepared and filed actively. We cover the reform in depth on our e-invoicing compliance in France page.

Who needs French VAT filing handled, and who must use a fiscal representative ?

The filing obligation and the representation obligation are two different questions. Conflating them is a frequent and costly error.

Any business holding a French VAT number must file CA3 returns. That includes EU-established companies, exempt-country non-EU companies, and non-EU companies that have appointed a fiscal representative. The filing itself can be done by the company directly, by a mandataire fiscal (tax agent without joint liability), or by a fiscal representative.

The representation question is separate. Non-EU companies outside the list of exempt countries must appoint a fiscal representative who assumes joint and several liability before they can register and file at all. EU-established companies and companies from exempt countries (including, post-Brexit, the United Kingdom) file directly without a representative. We cover this distinction in full on our fiscal representative in France page, and it is worth reading before deciding who files your returns.

The short version: if you are an EU company or from an exempt jurisdiction, you can have a CPA firm file your CA3 as your agent, no joint liability required. If you are a non-EU company outside the exempt list, the filing and the representation are bundled into one accredited role.

What a serious VAT filing service delivers each month ?

The checklist below separates a real filing service from a form-filler. It splits into three phases: what happens before submission, the submission itself, and what holds up under audit.

• Before submission, the work is reconciliation and recovery. The VAT figures are matched against your accounting records and, where relevant, your e-invoicing data. The four French rates (20% standard, 10%, 5.5%, 2.1%) are applied correctly, because a misclassified product erodes margin or creates exposure. Input VAT is reviewed line by line, since every deductible euro that goes unclaimed is money left on the table. Import VAT is reported and neutralised on the CA3 under the post-2022 reverse-charge mechanism.

• At submission, the CA3 is prepared, validated, and filed electronically through impots.gouv.fr or the EDI procedure. The annexes (DES, ERTVA, EMEBI) are filed on their own deadlines, not forgotten. The SEPA direct debit is coordinated so payment clears on time.

• After submission, the work is correction and archiving. Errors caught before the deadline are fixed with a corrected return; errors caught after are regularised on the following period's CA3, in the right direction. VAT records are kept in France, in French, for the statutory retention period, available on demand for inspection.

For companies that want VAT filing integrated with the rest of their French statutory obligations, this work sits naturally alongside our bookkeeping and broader tax compliance services.

5 filing mistakes we see most often

Recurring patterns from foreign-owned operations, roughly in order of frequency.

1. Treating the CA3 as the only obligation. A company files clean monthly CA3 returns for two years, then gets a customs query about missing ERTVA or EMEBI filings. The annexes have their own deadlines and their own portal. Forgetting them is the single most common gap.

2. Configuring the SEPA mandate late. The return is filed on time, but the payment fails because the direct debit was never set up, or was set up against a foreign account that France does not accept. The result is a late-payment surcharge on a return that was otherwise perfect.

3. Misapplying reduced rates. Applying 20% where 5.5% or 10% was due overstates output VAT and erodes margin. Applying a reduced rate where 20% was due understates VAT and creates an audit exposure. Rate classification by customs code is technical work, not a guess.

4. Filing CA12 on autopilot into 2027. Companies on the simplified regime that do not plan the transition will be caught by the 1 January 2027 abolition with a process built for an annual cadence and an obligation that has become monthly.

5. Self-filing without input VAT discipline. Companies that file their own returns to save fees frequently under-recover input VAT because nobody is systematically reviewing deductibility. The unclaimed VAT often exceeds what a professional service would have cost.

Why foreign companies bring their VAT filing to Vachon ?

3 reasons that come back from clients after onboarding.

• Senior CPA oversight, not a filing factory. Vachon is a chartered accountancy and audit firm registered with the Ordre des Experts-Comptables. Your VAT returns are prepared under the supervision of a senior practitioner who understands the interaction between VAT, corporate tax, and your statutory accounts. When the DGFiP raises a query, the response comes from someone accountable, in French.

• Bilingual reporting your group can read. The monthly VAT summary your parent receives is built for finance leadership in English, mapped to the figures your group consolidation needs. You get the French statutory reality translated into your reporting language and framework.

• One firm for the whole French stack. VAT filing does not sit alone. It connects to corporate tax, to the e-invoicing reform, to bookkeeping and statutory accounts, to payroll at the margin. Running them under one roof closes the seams that fragmented setups leak through. Our tax consulting in France and English-speaking chartered accountant teams work from the same files.

We are not a VAT-tech platform and we do not run a global EOR. We are a Paris CPA firm that files clean French VAT returns for foreign-owned operations, month after month, with a bias toward audit-ready documentation.

Hand the filing cycle to a partner who runs it every month

If your French VAT filing is overdue for a cleaner process, if you are about to register and want the cycle set up correctly from the first return, or if an annex obligation just surfaced that nobody was filing, the next step is a short scoping call. We will review your current filing setup, identify the obligations in scope, and give you a fixed-fee monthly proposal before you commit to anything.
