How to Legally Invoice Foreign Clients from France: VAT, Reverse Charge & Mandatory Rules

Working with international clients is one of the fastest ways to scale a freelance or consulting business in France. However, French invoicing rules are notoriously strict, and cross-border billing introduces distinct tax regulations.

Whether you are billing a startup in California, an agency in London, or a corporate client in Berlin, here is the complete guide to invoicing foreign clients from France legally and error-free.

1. The Core VAT Rule for B2B Intellectual Services

In France and across the EU, the tax treatment of intellectual services (consulting, software development, design, marketing) is governed by the place of supply rule (Article 259 of the French General Tax Code / CGI).

The B2B Rule: Business-to-business services are taxed where the client is established, not where the service provider is located.

Because your foreign professional client is established outside France, you do not charge French VAT (20%) on B2B invoices. However, you must include specific legal citations on your invoice depending on where your client is based.

2. Invoicing an EU-Based Business Client (B2B)

When providing services to a company established in another European Union member state (e.g., Germany, Spain, Ireland), you apply the Reverse Charge Mechanism (Autoliquidation).

Mandatory Invoice Requirements for EU B2B:

1. Invoice in Net Amounts (0% French VAT): You do not add French VAT to the total.
2. Include Intra-Community VAT Numbers: Your invoice must display both your French VAT number and your client’s valid EU VAT number. (Verify your client's VAT number on the official EUVIES database).
3. Mandatory Legal Mention: You must state the exact legal justification for omitting VAT on the invoice:

Mandatory Mention:

"Autoliquidation - Art. 196 de la Directive 2006/112/CE"
(or in English for your client: "Reverse charge - Article 196 of EU Directive 2006/112/EC")

Administrative Duty: The DES (Déclaration Européenne de Services)

Invoicing an EU client requires a monthly declaration to French customs called the DES. By the 10th working day of the following month, you must log into the French customs portal (douane.gouv.fr) and submit a summary of all services billed to EU businesses.

3. Invoicing a Non-EU Business Client (US, UK, Canada, Asia)

When billing clients outside the European Union (such as the United States or the United Kingdom post-Brexit), the transaction falls entirely outside the scope of French VAT.

Mandatory Invoice Requirements for Non-EU B2B:

1. Invoice in Net Amounts (0% French VAT): No French VAT is applied.
2. Client Identification: Outside the EU, clients do not have an EU VAT number. Instead, include their official local business registration number (e.g., US EIN, UK Company Number).
3. Mandatory Legal Mention: You must state the French tax code exemption:

Mandatory Mention:

"TVA non applicable - Art. 259-1 du Code Général des Impôts"
(or in English: "VAT not applicable - Art. 259-1 of the French General Tax Code")

4. Special Case: Auto-Entrepreneurs Under the VAT Threshold

If you operate as a Micro-Entrepreneur under the French VAT exemption threshold (Franchise en base de TVA — under €37,500/year for services), your invoices already exclude VAT for all clients.

• Priority Mention: Always include the standard micro-entrepreneur mention:"TVA non applicable, art. 293 B du CGI"
• For EU Clients: Even if you are under the VAT exemption threshold, when billing an EU business, you should also include their EU VAT number and the Reverse Charge mention to ensure their local tax compliance.

5. Invoicing in Foreign Currencies (USD, GBP, CHF)

You are legally permitted to issue invoices in foreign currencies (e.g., USD or GBP). However, French tax law imposes two strict conditions:

1. Accounting in Euros: For your French accounting and tax declarations (URSSAF, SIE), all amounts must be converted into Euros using the official European Central Bank (ECB) exchange rate on the date of invoice issuance.
2. Clear Rate Reference: If you issue the invoice in USD, it is best practice to note the ECB exchange rate used on the document itself.

6. Checklist: Essential Invoice Mentions for International Clients

Every invoice issued from France must contain the following core details:

7. What the 2026 E-Invoicing & E-Reporting Reform Means for Foreign Invoices

Under the French electronic invoicing reform, transactions with non-French clients are exempt from mandatory PDP e-invoicing routing (you can still send PDFs directly to your foreign clients).

However, foreign transactions fall under the e-reporting requirement. You are required to transmit transactional data (invoice number, client tax ID, country, net amount, currency) electronically to the French tax authorities (DGFiP) on a periodic basis (monthly or every 10 days depending on your VAT scheme). Using modern French accounting tools (e.g., Freebe, Indy, Pennylane) automates this e-reporting step seamlessly.
