How to Eliminate 20% of Your Upfront Costs: A Guide to France’s Import VAT Deferral

OUR GOAL
To provide an A-to-Z e-commerce logistics solution that would complete Amazon fulfillment network in the European Union.
On July 1, 2021, the EU's "E-commerce VAT Package" fundamentally changed how Value Added Tax (VAT) is collected on cross-border B2C sales to countries like France.
The single biggest change was the abolition of the €22 low-value consignment relief. Previously, most low-value items imported into the EU were VAT-exempt. The new rules eliminated this, meaning VAT is now due on every B2C product imported into the EU, regardless of its value.
This created a massive potential for customer delays, unexpected fees, and logistical nightmares at customs. To solve this, the EU introduced two new, simplified schemes: the One-Stop Shop (OSS) and the Import One-Stop Shop (IOSS).
While both simplify VAT, they apply to entirely different business scenarios. For an e-commerce manager shipping to France, understanding which to use is a critical customer experience and logistics issue. This guide explains the difference.
What is the One-Stop Shop (OSS)?
The One-Stop Shop (OSS) is a simplification scheme for VAT on B2C services and intra-EU cross-border sales of goods.
The keyword here is intra-EU.
Who is OSS for? (the Intra-EU seller)
The OSS scheme is designed for businesses that are established in the EU (or hold stock within an EU country) and sell goods from one EU member state to consumers (B2C) in another EU member state.
This is formally known as "intra-Community distance sales of goods."
OSS applies to you if:
- You are an EU-registered business (e.g., in Germany, Spain, Poland) shipping to customers in France.
- You are a non-EU business (e.g., from the US) but you hold your stock in an EU warehouse (e.g., in the Netherlands) and ship from that warehouse to customers in France.
How OSS works: a single return for all of Europe
Before OSS, if your German e-commerce store sold more than a certain amount (the "distance selling threshold") to French customers, you had to register for VAT in France, get a French VAT number, and file French VAT returns. If you also sold to Italy, Spain, and Belgium, you’d have to repeat the process in all those countries. It was an administrative nightmare.
OSS replaces this.
With OSS, you register for the scheme in just one EU country—your "Member State of Identification" (usually your home country or where your main warehouse is).
When you sell to a French customer from your German warehouse:
- You charge the French VAT rate (e.g., 20%) at checkout, not the German rate.
- You file one single, quarterly OSS return in Germany.
- In that return, you declare all your cross-border EU sales (your sales to France, Italy, Spain, etc.), broken down by country and VAT rate.
- You make one single payment of all the collected VAT to your home tax authority (e.g., the German Bundeszentralamt für Steuern).
- The German tax office then automatically distributes the correct VAT amounts to the French, Italian, and Spanish tax authorities.
Benefit: You no longer need to register for VAT in every single EU country you sell to. You manage all your cross-border B2C VAT through one simple, quarterly electronic return.
What is the Import One-Stop Shop (IOSS)?
This is the scheme that gets the most attention, as it deals with the new rules for imports.
The Import One-Stop Shop (IOSS) is a simplification scheme for VAT on imported B2C goods in consignments with an intrinsic value not exceeding €150.
The keywords here are import and €150.
Who is IOSS for? (The non-EU seller)
The IOSS scheme is designed for businesses based outside the EU that sell goods from a non-EU country (e.g., UK, USA, China) directly to consumers inside the EU (e.g., in France).
It only applies to individual packages (consignments) valued at €150 or less.
IOSS applies to you if:
- You are a UK-based store shipping a €70 shirt from your London warehouse to a customer in Paris.
- You are a US-based dropshipper selling €30 gadgets that ship from China to a customer in Lyon.
How IOSS works: creating a "green channel" at customs
The purpose of IOSS is to avoid the customer experience nightmare of "VAT due upon delivery."
Before IOSS (and after the €22 threshold was removed), that €70 shirt from the UK would arrive at French customs. La Poste (or another carrier) would have to stop it, assess the 20% VAT (€14), and often charge the customer an €8-€15 "handling fee" to process this payment. The customer, who thought they had paid in full, is now angry and may refuse the package.
IOSS prevents this entirely.
When you register for IOSS (you can do this in any single EU state, like France):
- You receive a unique IOSS number. Note: non-EU established sellers usually must appoint an EU IOSS intermediary (a fiscal representative) to register and access the scheme—check whether your country has a specific mutual agreement that changes that requirement.
- When a French customer buys that €70 shirt, your website collects the 20% French VAT (€14) at the point of sale. The customer pays the full, final price at checkout.
- When you ship the parcel, you (or your carrier) must electronically transmit your IOSS number to customs as part of the declaration data.
- When the parcel arrives at French customs, the system sees the valid IOSS number. It knows the VAT has already been collected.
- The parcel is "green-lighted" and passes through customs for immediate delivery to the customer with no extra fees or delays.
- IOSS declarations are normally submitted monthly to the Member State of identification; the collected VAT is remitted via that monthly return.
Benefit: You provide a seamless, Delivery Duty Paid (DDP-like) experience for your customers, which is essential for conversion and retention.
OSS vs. IOSS: head-to-head comparison
One-Stop Shop (OSS) | Import One-Stop Shop (IOSS) | |
Who is it for? | EU businesses (or non-EU with EU stock) selling cross-border within the EU. | Non-EU businesses selling from outside the EU to consumers inside the EU. |
What does it cover? | Intra-Community distance sales of goods (any value) & B2C services. | Imports of B2C goods. |
Consignment Value Limit | No value limit. | Only for consignments of €150 or less. |
VAT Collection | Charge the VAT rate of the customer's EU country at checkout. | Charge the VAT rate of the customer's EU country at checkout. |
VAT Return Frequency | Quarterly | Monthly |
Example Scenario | A warehouse in Spain ships a €300 order to a customer in France. | A warehouse in the UK ships a €100 order to a customer in France. |
What about imports over €150?
This is the most common point of confusion and a major logistical pain point.
The IOSS scheme cannot be used for any consignment with an intrinsic value over €150.
So, what happens when your UK-based store sells a €200 coat to a customer in France? You have two options, and one is far superior to the other.
The standard method (DDU - delivery duty unpaid)
This is the "default" and most high-friction method.
- You ship the €200 coat without charging VAT.
- The package arrives at French customs.
- Customs stops the package and assesses:
- Import VAT (e.g., 20% of €200 = €40)
- Customs Duties (if applicable, e.g., 12% on apparel = €24)
- The carrier (e.g., La Poste, Chronopost) pays these fees on the customer's behalf and then contacts the customer to demand reimbursement plus a hefty administrative/handling fee.
- Your French customer is now faced with an unexpected bill of €70+ to receive an item they already paid for.
Result: This is a catastrophic customer experience. It leads to high rates of refused packages, customer complaints, chargebacks, and ultimately, the loss of your French customer base.
The DDP solution (delivery duty paid)
This is the professional solution that top e-commerce brands use.
- You find a way to pay the import VAT and duties yourself, so the customer pays nothing upon delivery.
- This requires a logistical setup. You must have a customs broker or logistics partner in the EU (ideally in France, your port of entry) who can act as your declarant.
- Your partner manages the customs clearance, pays the VAT and duties on your behalf, and then bills them back to you.
- The package is delivered to the customer seamlessly, just like a domestic purchase.
This "DDP" model is the only viable strategy for selling high-value goods to the EU post-2021. It requires a reliable logistics partner on the ground in your destination market.
How your logistics strategy intersects with VAT compliance
Your choice of VAT scheme (OSS, IOSS, or DDP) is not just a finance decision; it directly dictates your logistics and fulfillment strategy.
Logistics for an OSS seller
If you are an EU-based seller using OSS, your primary logistical challenge is speed and cost of cross-border shipping. For example, shipping from a warehouse in Poland to a customer in rural France can be slow and expensive.
This is why many high-volume OSS sellers adopt a multi-warehouse strategy. By placing stock in a fulfillment center in France, you can:
- Drastically cut delivery times for your French customers (e.g., next-day delivery).
- Reduce shipping costs.
Note: Sales from a French warehouse to a French customer are then considered domestic sales, subject to standard French VAT rules, not OSS. Sales from that French warehouse to, say, Germany would then be declared via OSS.)
Logistics for an IOSS Seller
If you are a non-EU seller using IOSS, your primary logistical challenge is data and customs compliance.
- Data is king: Your carrier must be able to transmit your IOSS number and accurate customs data (HS codes, product values) electronically for every single package. Failure to do so means the package will be stopped at customs, and the customer will be double-charged for VAT.
- Intermediary vs. 3PL: To register for IOSS, most non-EU businesses must appoint a VAT intermediary—a fiscal representative established in the EU (like in France) who is jointly liable for your VAT. This is typically a tax or accounting firm. This is separate from your logistics partner (3PL), which is the company physically moving your goods. Finding a 3PL partner in France that understands the IOSS data requirements is crucial for success.
Logistics for high-value DDP imports
If you are selling goods over €150, your 3PL partner is your strategy.
You cannot succeed without a partner in France who can act as your customs declarant (or has a deep partnership with one). This partner will manage the complex DDP import process, clear your goods in bulk, and handle last-mile delivery.
This is often the most robust solution. Many non-EU sellers bulk-ship their goods to a French 3PL, clear customs via DDP, and then place the inventory in that French warehouse. From there, all sales to French customers are simple domestic sales, and sales to other EU countries can be managed via OSS (as they are now "intra-EU" sales).
Your go-forward checklist: choosing the right path for France
Use this simple checklist to determine your next steps.
- Where is your business AND your stock located?
- In an EU country (but not France): You need to use OSS for your B2C sales to France.
- Outside the EU (e.g., UK, US, China): Go to question 2.
- What is the value of your typical consignments?
- If most consignments are ≤ €150, using IOSS is strongly recommended because it allows VAT to be collected at checkout and usually prevents VAT-on-delivery and handling charges for customers. IOSS is optional (alternatives exist such as special arrangements handled by postal/courier operators), but not using it often results in a worse customer experience.
- A mix of high and low-value items: You need a dual strategy. Use IOSS for all <€150 shipments and find a French logistics partner to manage a DDP solution for all >€150 shipments.
- Almost all are over €150: You can skip IOSS. Your entire focus must be on building a robust DDP import and fulfillment model with a customs-savvy French partner.
TL;DR: OSS vs. IOSS in 60 seconds
- Use OSS (One-Stop Shop) if: You sell goods to B2C customers in France but ship from a warehouse inside another EU country (e.g., from Germany, Spain). OSS lets you manage all your cross-border EU B2C VAT in one single, quarterly return in your home country. There is no consignment value limit.
- Use IOSS (Import One-Stop Shop) if: You sell goods to B2C customers in France but ship from outside the EU (e.g., from the UK, US, China) AND the consignment value is €150 or less. IOSS lets you collect the French VAT at checkout, so your customer pays no extra fees on delivery.
- What about imports over €150? Neither scheme applies. You must use standard customs procedures. To avoid hitting your customer with import VAT and duties on delivery, the only viable solution is shipping via DDP (Delivery Duty Paid), which requires a logistics partner in France to manage the import.
