Declaring & Updating Storage Locations for OSS in France
Summary
When registering for OSS (One-Stop-Shop) in France, you must declare all warehouse locations where your goods are stored — in France and across the EU.
This is required so the French tax authorities can correctly link your storage setup to your VAT and OSS reporting.
✅ At registration:
Provide full details of every warehouse or fulfilment centre (including Amazon FBA or 3PL providers).
⚙️ If your storage setup changes (new, removed, or relocated warehouse):
You must inform hellotax immediately with:
New warehouse address and country
Start date of storage
Provider name (e.g., Amazon, 3PL)
hellotax will update your OSS registration with the French tax authorities.
⚠️ If you don’t update:
Your quarterly OSS filing may be rejected or delayed, and the tax office may request clarification or initiate compliance checks.
💡 Tip:
If you use Amazon FBA or Pan-EU, check your Seller Central inventory monthly — storage countries can change automatically.
Always notify hellotax as soon as new countries appear.
Get the facts!
When registering for OSS in France, it is important to understand that the French tax authorities require full transparency regarding where your goods are stored — both in France and in other EU countries.
This information allows the authorities to determine where taxable transactions take place and ensures your VAT reporting under OSS remains accurate and compliant.
1️⃣ Why warehouse information is required
When applying for OSS registration in France, the tax authorities require:
The full addresses of all warehouses or fulfilment centres where your goods are stored
Confirmation of whether goods are stored in France or in other EU countries
Details of third-party fulfilment providers (such as Amazon FBA or other 3PL warehouses)
This information ensures your declared business activities align with your VAT and OSS obligations.
If warehouse details are incomplete or incorrect, your OSS registration may be delayed or your filings may encounter issues later.
2️⃣ What happens if you change or add storage locations
Once your OSS registration is active, you must keep your storage information up to date.
You are required to notify the French tax authorities whenever:
You begin storing goods in a new warehouse (inside or outside France)
You stop using an existing warehouse
You add or remove an Amazon fulfilment country (for example, if FBA expands your storage network to Poland, Germany, Spain, etc.)
⚠️ Important:
If your OSS registration does not reflect your actual storage structure, your quarterly OSS return may be rejected.
Inconsistent or outdated information may also trigger compliance checks or formal clarification requests from the tax authorities.
3️⃣ How to update your storage information
If your storage locations change:
Step 1 – Notify hellotax immediately
Send an email to your Account Manager or Registration Assistant with:
New warehouse or fulfilment centre address
Country of storage
Date storage began (or will begin)
Provider name (Amazon, 3PL, etc.)
Step 2 – Update submitted to French authorities
hellotax will prepare and submit the required amendment to the French tax office on your behalf.
Step 3 – Confirmation
Updates are typically processed within a few business days.
We will confirm once the amendment has been officially recorded.
4️⃣ Why timely updates are essential
Keeping your OSS registration accurate is critical to:
✅ Ensuring your OSS returns are accepted without delays
✅ Avoiding rejections or penalties for inaccurate reporting
✅ Maintaining compliance when expanding into new EU markets
Even if goods are temporarily stored in another EU country — for example, through Amazon’s Pan-EU FBA programme — you are still required to notify and update your OSS registration accordingly.
5️⃣ Summary Table
| Action | When Required | What to Provide |
|---|---|---|
| Initial warehouse declaration | During OSS registration | Full list of storage addresses and countries |
| Update to storage locations | When adding, changing, or removing a warehouse | New address, country, provider name, start date |
| Responsible authority | French Tax Authorities | Amendments submitted by hellotax on your behalf |
| Risk of not updating | If storage changes are not reported | OSS filings may be rejected or delayed |
💡 Final Tip:
If you use Amazon FBA or Pan-EU fulfilment, Amazon may automatically redistribute your stock across EU warehouses.
We strongly recommend reviewing your Amazon Seller Central inventory reports monthly and informing hellotax immediately if new storage countries appear.
