OUR GOAL
To provide an A-to-Z e-commerce logistics solution that would complete Amazon fulfillment network in the European Union.
Expanding your e-commerce business into EU market brings one major challenge: VAT compliance. Since the EU's E-commerce VAT Package (July 2021), rules for B2C sales have changed significantly. VAT is now due on every import, regardless of value.
To simplify this, the EU introduced the Import One-Stop Shop (IOSS) scheme. However, navigating this new system has created confusion around two key roles: the IOSS (FIOSS) Intermediary and the Fiscal Representative.
In this guide, we'll demystify both roles, compare their functions, and use practical scenarios to help you determine exactly which partner your business needs for smooth, compliant growth in the EU.
What is an IOSS (FIOSS) intermediary?
To understand the Intermediary, we must first understand the scheme it serves: the Import One-Stop Shop (IOSS).
The IOSS scheme explained
The IOSS is a voluntary scheme designed to simplify VAT compliance for e-commerce businesses selling goods to EU consumers from outside the EU.
- What it covers: B2C consignments with an intrinsic value of €150 or less.
- How it works: A seller registers for IOSS in a single EU member state. They are given a unique IOSS number. When a sale is made to an EU consumer (e.g., a $50 shirt sold from the US to a customer in France), the seller charges the French VAT rate (20%) at the point-of-sale.
- The benefit: The parcel, which travels with the seller's IOSS number, is treated as "VAT-paid." It benefits from a "green channel" at customs, meaning the customer faces no surprise import VAT charges or handling fees upon delivery. The seller then files a single, monthly IOSS return in their chosen EU state, declaring all such sales across all 27 EU member states.
The role of the IOSS intermediary
Here is the crucial part: For most non-EU businesses, participation in IOSS is not direct.
A business established outside the European Union (e.g., in the UK, USA, or China) must appoint an EU-established intermediary to use the IOSS scheme.
An IOSS Intermediary is a taxable person (like a specialized compliance firm, tax advisor, or logistics provider) established within the EU who is appointed by the non-EU seller to manage their IOSS obligations.
(Note on terminology: The term "FIOSS" or "Fiscal Intermediary One-Stop Shop" is often used interchangeably with "IOSS Intermediary." While "IOSS Intermediary" is the official legal term, FIOSS is common industry jargon referring to the same function.)
Key responsibilities of an IOSS intermediary
When you appoint an Intermediary, they take on significant responsibility. Critically, the Intermediary becomes jointly and severally liable for the VAT due. This means if you fail to pay, the tax authorities can pursue the Intermediary for your debt.
Because of this risk, intermediaries are highly selective and perform thorough due diligence. Their primary functions include:
- IOSS Registration: Registering your business for the IOSS scheme in their Member State of establishment.
- Monthly Declarations: Submitting your monthly IOSS VAT returns, detailing all eligible sales by country and VAT rate.
- VAT Payment: Facilitating the payment of the declared VAT to the tax authorities.
- Record-Keeping: Maintaining detailed records of your IOSS-eligible transactions for potential audits.
- Communication: Acting as the primary contact point between your business and the EU tax authorities for all IOSS-related matters.
Who needs an IOSS intermediary?
You must appoint an IOSS Intermediary if:
- You are an e-commerce seller not established in the EU (e.g., based in the US, UK, Canada, China).
- You sell B2C consignments valued at €150 or less from outside the EU to customers inside the EU.
- You choose to use the IOSS scheme to offer a seamless, duty-paid delivery experience.
(Exception: Businesses established in a non-EU country with which the EU has a VAT mutual assistance agreement, like Norway, are not required to appoint an Intermediary.)

What is a fiscal representative?
The fiscal representative is a broader, and more traditional VAT compliance role that pre-dates the 2021 E-commerce VAT Package.
A fiscal representative is a local entity (like a tax agency or accounting firm) within an EU Member State that is appointed by a non-EU business to handle its standard, local VAT obligations in that specific country.
This role is not tied to a special scheme like IOSS. It is tied to a standard VAT registration.
Why would you need a standard VAT registration?
A non-EU business typically needs a standard VAT registration in an EU country if it performs transactions that cannot be covered by the IOSS or OSS schemes. The most common trigger for e-commerce businesses is holding stock within that EU country.
If you store your goods in a warehouse or fulfillment center in France (for example, at a 3PL) to serve your French and European customers, you have created a "taxable presence" in France.
Other triggers include:
- Making B2B (business-to-business) sales within that country.
- Exceeding certain local thresholds for specific types of sales.
Making B2C sales from that stock location to customers in the same country (e.g., stock in France sold to a French customer).
The fiscal representative mandate
Crucially, many EU Member States mandate that a non-EU business must appoint a fiscal representative to be able to obtain a standard VAT registration. Countries like France, Spain, Poland, and Italy have this requirement.
Other countries, like Germany or the Netherlands, do not always mandate it, but it is often highly recommended for non-EU businesses to manage complex local filings.
Key responsibilities of a fiscal representative
Like the intermediary, a fiscal representative is also jointly and severally liable for the VAT debts of the business they represent. This is a high-stakes role.
Their responsibilities are typically much broader than an IOSS Intermediary's:
- VAT registration: Applying for and obtaining a local VAT number for your business in that specific country.
- Periodic VAT returns: Filing regular (usually monthly or quarterly) domestic VAT returns, which are far more complex than IOSS returns.
- Other filings: Managing other compliance filings as needed, such as EC Sales Lists (ESL) for B2B sales or Intrastat declarations for the movement of goods.
- VAT payments/refunds: Managing the payment of VAT due or claiming VAT refunds on your behalf (e.g., on import VAT or local purchases).
- Tax authority liaison: Representing your business in all dealings, audits, and queries with the local tax office.
IOSS intermediary vs. fiscal representative: head-to-head comparison
The confusion is understandable, as both are EU-based entities that handle VAT for non-EU businesses. However, their scope, purpose, and triggers are entirely different.
This table breaks down the key distinctions:
Feature | IOSS (FIOSS) Intermediary | Fiscal Representative |
Primary Scheme | IOSS (Import One-Stop Shop) | Standard VAT Registration |
Primary Trigger | Selling goods $\le$ €150 from outside the EU. | Holding stock inside an EU country, or other local taxable activities. |
Geographic Scope | Pan-EU (All 27 States) via a single registration and return. | Single EU Member State. (You would need a separate one for each country where you are registered). |
Type of Return | Monthly IOSS Return (Simplified declaration of B2C sales $\le$ €150). | Monthly/Quarterly Domestic VAT Return (Complex, includes all sales types, input VAT, etc.). |
Transactions Covered | B2C imports $\le$ €150 only. | All taxable transactions in that country (B2B, B2C, domestic, imports, acquisitions). |
Liability | Jointly and severally liable for the IOSS VAT debt. | Jointly and severally liable for all VAT debts in that specific country. |
Which one do you need?
Let's apply this knowledge to common e-commerce scenarios.
Dropshipper (non-EU)
- Your Business: You are a US-based store on Shopify. You dropship t-shirts (Average Order Value: $40) from a supplier in China directly to customers in Germany, France, and Spain. You hold no stock in the EU.
- Analysis: All your sales are B2C imports under €150. You are a non-EU seller. You want to avoid your customers paying import VAT.
- Verdict: You need an IOSS Intermediary. You do not need a Fiscal Representative, as you have no taxable presence (no stock) in the EU.
Amazon FBA seller (non-EU)
- Your business: You are a UK-based company. You send bulk shipments of your products to an Amazon FBA warehouse in France to fulfill orders for French customers.
- Analysis: You are holding stock in France. This immediately triggers the requirement for a standard French VAT registration. Because you are a non-EU (UK) business, France mandates you appoint a local representative.
- Verdict: You need a fiscal representative in France. The IOSS Intermediary is irrelevant for these transactions, as the goods are already inside the EU. (Note: For your sales from the French warehouse to customers in other EU countries, like Germany or Spain, you will use the OSS (One-Stop Shop) scheme, which your French Fiscal Representative can manage for you.)
High-value retailer (non-EU)
- Your business: You are a Canadian store selling luxury handbags ($800) directly to EU consumers. You ship from Canada.
- Analysis: Your goods are over the €150 IOSS threshold. The IOSS scheme is not available to you.
- Verdict: You need neither an IOSS intermediary nor a fiscal representative (in the traditional sense). Your sales will be handled via standard customs procedures, with VAT and duties paid upon import (known as Delivered at Place/DAP).
- Alternative (DDP): If you wanted to provide a premium Delivered Duty Paid (DDP) experience, you would likely need to VAT register in every single EU country you sell to, which would require multiple fiscal representatives—a highly complex and costly setup.
3PL Partner (the hybrid model)
- Your business: You are a US e-commerce brand. You use a 3PL partner in France (like FlexLogistique) to store your 10 best-selling products for fast EU fulfillment. You also dropship your extended-range (100+ other products, all < €150) from your US warehouse.
- Analysis: You have two distinct supply chains.
- Stock in France: This triggers a mandatory French VAT registration, which in turn requires you to appoint a fiscal representative in France.
- Dropshipping from US: These are B2C imports < €150. To provide a good customer experience, you want to use IOSS.
- Verdict: You need BOTH. You need a fiscal representative in France to handle your standard VAT obligations for the stock held there. You also need an IOSS intermediary (which can be in France or any other EU state) to manage the VAT for your low-value dropshipments from the US.

Your logistics strategy dictates your VAT strategy
This brings us to the most critical takeaway: Your VAT compliance model is a direct consequence of your logistics and fulfillment decisions.
You cannot choose an Intermediary or a Fiscal Representative in a vacuum. The choice is dictated by where your goods are located when a customer clicks "buy."
- If your stock is outside the EU: Your primary concern is import VAT. Your best tool is the IOSS scheme, which requires an IOSS Intermediary.
- If your stock is inside the EU (e.g., at a 3PL): Your primary concern is domestic and intra-community VAT. Your requirement is a standard VAT registration, which (for non-EU sellers) mandates a fiscal representative.
This is why partnering with a sophisticated 3PL and fulfillment provider is so crucial. A good logistics partner doesn't just move boxes; they provide the foundation for your entire European strategy. They should be able to:
- Provide clarity: Advise you on how using their warehouse (e.g., in France) will impact your VAT obligations.
- Enable compliance: Provide you with the transaction data, inventory reports, and shipping documents necessary for your compliance partner to file accurate returns.
- Offer a network: Connect you with trusted, vetted partners—both IOSS intermediaries and fiscal representatives—to create a seamless, end-to-end solution.
Choose the right partner for your model
To recap the core difference in one sentence:
An IOSS intermediary handles VAT for your low-value imports for all 27 EU countries under one simplified scheme, while a fiscal representative manages your entire, standard VAT obligations within one specific EU country where you have a taxable presence.
Understanding this distinction is the first step toward scalable, compliant success in the EU. Before you engage any compliance firm, map out your supply chain. Analyze your Average Order Value (AOV) and, most importantly, decide where your inventory will be stored.
Answering these logistical questions will automatically illuminate the correct VAT path, ensuring you choose the right partner, stay compliant, and focus on what you do best: growing your brand.
