Your French VAT registration and/or OSS registration has now been officially issued — excellent news!

This means your registration in France is complete, and you are now ready to begin compliant trading, invoicing, and VAT reporting.

This article explains what you need to do next, how to manage communication with the French tax authorities, and how to keep your hellotax account fully updated.

✅ What You Should Do Now

1️⃣ Forward All Tax Office Letters or Emails to Your Account Manager

Once your VAT or OSS registration is active, the French tax authorities (Service des Impôts des Entreprises – SIE) may send:

• Registration confirmations

• Requests for additional information

• Filing reminders

• Payment notices

• General correspondence

If you receive any letter or email directly, please forward it immediately to your hellotax Account Manager.

Why this matters:

• The document will be uploaded into your hellotax software account

• We maintain a complete compliance history

• This ensures smooth handling during audits or tax authority queries

• Nothing important gets missed

Keeping a full correspondence trail is essential for long-term compliance in France.

2️⃣ Upload All Transaction Data on Time (Mandatory)

To prepare accurate French VAT returns and, where applicable, OSS reports, all transaction data (including purchases and stock movements) must be uploaded to your hellotax account by:

📅 The 4th day of the month following the reporting period

This applies to:

• Marketplace sales (Amazon, eBay, etc.)

• Webshop sales

• Manual invoices

• Returns and refunds

• Stock transfers and movements

🔗 You can find full upload instructions in your hellotax account under:
Data Upload / Integration

Incomplete or delayed data uploads may result in:

• Incorrect VAT filings

• Penalties or interest charges

• Tax office clarification requests

Accurate and timely uploads are mandatory for compliance.

3️⃣ We Will Add Your New VAT Details to Your Account

hellotax will automatically enter into your software account:

• Your French VAT number (Numéro de TVA intracommunautaire)

• Your SIREN/SIRET number (if applicable)

• Your effective VAT start date

This ensures:

• Correct reporting periods

• Accurate VAT calculations

• No issues with your first VAT return

4️⃣ Inform hellotax of Any Other VAT or OSS Registrations

If your company holds VAT numbers in other EU countries or has an OSS registration elsewhere (even if hellotax does not manage those countries), you must inform us.

Why this is important:

• Other VAT numbers affect intra-EU reporting

• OSS registrations determine where VAT must be declared

• Cross-border sales impact French VAT obligations

• It prevents duplicate or conflicting filings

• EU tax authorities exchange VAT data between Member States

Having a complete overview of your VAT registrations ensures accurate and compliant reporting across the EU.

📌 Summary of Your Responsibilities

⚠️ Important Reminder

In France, VAT returns must be filed electronically, and VAT payments are generally made via SEPA direct debit from a bank account within the SEPA zone.

Failure to file or pay on time may result in:

• Late payment interest (intérêts de retard)

• Penalties (majorations)

• Formal notices from the tax office

• Potential compliance investigations

Maintaining proactive communication and accurate reporting helps avoid these risks.
