The introduction of the EU One Stop Shop, usually referred to as OSS, changed the way many companies manage VAT on cross-border B2C sales within the European Union. For many e-commerce sellers, digital service providers and international businesses, OSS can reduce the need to register for VAT in several EU countries and can centralise part of the reporting process through a single electronic return.
However, one of the most common mistakes made by foreign companies selling into Italy is assuming that OSS automatically replaces any Italian VAT obligation. That is not correct. OSS is a simplification mechanism, not a general exemption from Italian VAT registration. It can be extremely useful in the right scenario, but it does not cover every sale, every supply chain or every operational model.
This guide explains the practical difference between OSS and Italian VAT registration, when OSS may be enough, when a local Italian VAT number is still needed, and what foreign businesses should check before selling goods or services to Italian customers.
What is the EU One Stop Shop?
The One Stop Shop is an optional EU VAT simplification system that allows businesses to declare and pay VAT due on certain eligible cross-border B2C supplies through a single Member State of identification. In practical terms, instead of filing separate VAT returns in every Member State where eligible consumers are located, the business may submit a single OSS return in the country where it is registered for the scheme.
The simplification is especially relevant for online sellers that supply goods to private consumers in different EU Member States and for providers of certain services to non-taxable persons. For example, an EU company established in Germany that sells goods from Germany to private customers in Italy, France and Spain may be able to declare the Italian, French and Spanish VAT through the OSS Union scheme, rather than registering separately in each country for those sales.
Important point: OSS is a reporting and payment simplification. It does not change the place of supply rules, it does not remove the need to charge the correct VAT rate, and it does not automatically solve local VAT obligations that are outside the scope of the scheme.
Union OSS, non-Union OSS and IOSS: the three concepts to distinguish
When companies talk about “OSS”, they often mix together different regimes. From an operational perspective it is essential to distinguish the Union OSS, the non-Union OSS and the Import One Stop Shop, known as IOSS. They are connected by the same simplification logic, but they apply to different transactions.
| Scheme | Main use | Typical example | Key limitation |
|---|---|---|---|
| Union OSS | Eligible intra-EU B2C distance sales of goods and certain services. | EU seller ships goods from France to private consumers in Italy. | It does not cover domestic Italian sales from Italian stock. |
| Non-Union OSS | Certain B2C services supplied by non-EU businesses to EU consumers. | Non-EU provider supplies digital or other eligible services to Italian consumers. | It is not a general solution for goods stored or imported into Italy. |
| IOSS | Distance sales of imported goods in consignments not exceeding EUR 150. | Goods are shipped from a third country directly to EU consumers. | It does not apply to consignments above EUR 150 or to goods already stored in Italy. |
The European Commission describes OSS as a way to register, declare and pay VAT through a single electronic portal for the transactions covered by the scheme. The Import One Stop Shop was introduced to simplify VAT on distance sales of low-value goods imported from third countries or territories into the EU. These simplifications are powerful, but they must be matched carefully with the seller’s logistics and invoicing model.
When OSS may be enough for sales to Italy
OSS may be enough where the business makes eligible cross-border B2C supplies to Italian consumers without creating a separate Italian VAT obligation. The most common case is a distance sale of goods from another EU Member State to private customers in Italy, where the seller is registered for the OSS Union scheme in its Member State of identification and declares Italian VAT through the OSS return.
Consider a French e-commerce company that stores all its products in France and sells online to private customers in Italy. The goods are shipped from France to the Italian consumer. In that case, if the company uses OSS correctly, the Italian VAT due on those B2C sales may be reported through the French OSS portal. The company still needs to apply the correct Italian VAT rate, but it may not need a separate Italian VAT registration solely for those eligible distance sales.
Digital services and cross-border B2C services
OSS can also be relevant for certain B2C services, including digital services and other supplies covered by the regime. For businesses selling software subscriptions, online platforms, streaming access, downloadable products or electronically supplied services to Italian consumers, the place of supply rules may require VAT in the customer’s Member State. OSS can centralise the reporting of that VAT if the conditions are met.
When Italian VAT registration may still be required
The key practical question is not “Do I sell to Italy?” but “What exactly happens in Italy?”. OSS is often not enough where the seller stores goods in Italy, imports goods into Italy, makes domestic Italian supplies, purchases and resells locally, or has operational arrangements that create Italian VAT obligations outside the scope of OSS.
The most important cases are the following.
1. Goods stored in Italy
If a foreign company stores goods in Italy — for example in a warehouse, fulfilment centre or Amazon FBA facility — the VAT position changes significantly. Sales from Italian stock to Italian customers are domestic Italian supplies, not cross-border distance sales from another Member State. OSS does not generally replace the local VAT registration needed to manage those Italian domestic supplies.
This is why many Amazon FBA sellers discover that OSS alone is not sufficient. Participation in Pan-European FBA or the use of Italian fulfilment stock may trigger the need to obtain an Italian VAT number, even if the seller already uses OSS in another EU country.
2. Domestic sales within Italy
When the movement of goods starts and ends in Italy, the sale is not a cross-border distance sale. A foreign company that sells goods located in Italy to Italian private customers is making a domestic Italian transaction. In this scenario, Italian VAT registration is usually the central compliance point.
3. Imports into Italy
Where goods are imported into Italy from outside the EU, customs and import VAT issues must be considered separately. IOSS may be relevant for direct distance sales of imported low-value goods not exceeding EUR 150, but it is not a general solution for all import models. Goods imported in bulk into Italy for later storage and resale may require Italian VAT handling and cannot simply be treated as OSS distance sales.
4. B2B transactions and reverse charge analysis
OSS is designed mainly for B2C transactions covered by the regime. B2B supplies require a separate VAT analysis. Depending on the transaction, reverse charge rules, intra-Community supply rules, local invoicing obligations or Italian VAT registration may become relevant. A company selling both to consumers and VAT-registered businesses should not assume that one OSS setup covers all its operations.
5. Possible fixed establishment or permanent structure issues
VAT registration is not the same as having a fixed establishment, and not every warehouse or logistics arrangement creates a fixed establishment. However, a business with people, technical resources, operational control or a structured local presence in Italy should assess whether the Italian presence has broader VAT and tax implications. OSS does not solve those questions.
OSS is often correctly used for cross-border B2C reporting, but incorrectly used as a substitute for Italian VAT registration where stock is already in Italy. This is one of the most common risk areas for e-commerce sellers.
OSS vs Italian VAT registration: practical comparison
| Scenario | Can OSS help? | Is Italian VAT registration still possible or likely? | Reason |
|---|---|---|---|
| Goods shipped from another EU country to Italian consumers | Yes, if eligible and properly registered. | Not necessarily for those sales alone. | Cross-border B2C distance sale may be reported through OSS. |
| Goods stored in Italy and sold to Italian consumers | No, not for the domestic Italian supply. | Yes, commonly required. | The sale is domestic because the goods are already in Italy. |
| Amazon FBA stock moved to Italy | OSS may help for some later cross-border sales. | Yes, if Italian stock is used. | Storage in Italy generally creates local VAT compliance obligations. |
| Digital services to Italian private customers | Often yes, if the service is within scope. | Depends on the overall business model. | OSS can centralise VAT due in the customer’s Member State. |
| Imports from outside the EU directly to Italian consumers below EUR 150 | IOSS may help. | Depends on the import chain and role of the seller/platform. | IOSS is a separate import simplification, not the same as Union OSS. |
| B2B sales to Italian VAT-registered customers | Usually no. | Depends on transaction and reverse charge rules. | OSS is not a general B2B reporting system. |
OSS and Amazon FBA in Italy
Amazon FBA deserves separate attention because the seller may not always realise where inventory is stored or moved. From a VAT perspective, the physical location of the goods is crucial. If Amazon stores stock in Italy, or if the seller authorises inventory movements into Italian fulfilment centres, the seller may need an Italian VAT number even if sales to other EU countries are declared through OSS.
For example, a non-Italian seller may initially ship goods from Germany to Italian consumers and report those sales through OSS. Later, the seller activates a logistics programme that allows stock to be moved into Italy. Once the goods are stored in Italy, sales from that stock to Italian consumers are no longer simply German-to-Italy distance sales. The Italian VAT analysis must be updated.
This is why Amazon sellers should review fulfilment settings, inventory reports, country of storage permissions and cross-border programme participation before concluding that OSS is enough.
Marketplace deemed supplier rules: why the platform may matter
EU VAT e-commerce rules also introduced specific rules under which electronic interfaces, such as marketplaces or platforms, may be treated as deemed suppliers for certain transactions. This can shift VAT collection and reporting obligations to the platform in specific cases, especially for certain sales by non-EU sellers or low-value imported goods.
However, sellers should not rely on a general assumption that “the marketplace handles VAT”. The platform may be responsible for some transactions, while the seller remains responsible for others, including inventory movements, imports, B2B transactions, local purchases, or sales not covered by deemed supplier rules. The correct answer depends on the exact flow of goods, the status of the seller, the value of the consignment, the customer type and the contractual structure.
IOSS vs OSS: why the distinction matters for Italy
IOSS is often confused with OSS, but the distinction is essential. IOSS is focused on distance sales of imported goods in consignments not exceeding EUR 150, shipped from a third country or territory to EU consumers. OSS, by contrast, is used for eligible intra-EU B2C supplies and certain services.
If a UK, US or Chinese seller ships a low-value parcel directly to an Italian consumer from outside the EU, IOSS may be relevant. If the same seller imports goods into Italy in bulk, stores them in an Italian warehouse and then sells them to Italian consumers, that is a different model. IOSS is not designed to cover domestic sales from Italian stock.
Records, returns and deadlines
Using OSS does not mean that compliance becomes automatic. Businesses using OSS must keep suitable records, apply the correct VAT rates for each Member State, file OSS returns and pay the VAT due through the Member State of identification. The Italian VAT rate may vary depending on the product or service supplied, so the seller’s systems must classify products correctly.
In Italy, OSS return deadlines are tied to quarterly reporting. Italian VAT registration, by contrast, may involve ordinary Italian VAT obligations such as VAT ledgers, periodic VAT settlements, annual VAT returns, e-invoicing analysis and other domestic compliance requirements depending on the specific case.
| Compliance area | OSS | Italian VAT registration |
|---|---|---|
| VAT return logic | Centralised OSS return for covered transactions. | Italian VAT returns and local reporting obligations. |
| Transactions covered | Only eligible B2C supplies under the scheme. | Italian domestic and other transactions within the local VAT scope. |
| VAT rates | Rates of each customer’s Member State must be applied. | Italian VAT rules and rates apply to Italian supplies. |
| Record keeping | OSS records must be retained for audit purposes. | Italian accounting and VAT records may be required. |
| Fiscal representative | Depends on the scheme and seller’s status. | Often relevant for non-EU businesses requiring Italian VAT registration. |
Practical examples
Example 1: EU seller shipping from France to Italy
A French company sells consumer goods online to Italian private customers. The goods are stored only in France and shipped from France to Italy after each sale. The company may use the Union OSS to declare Italian VAT on those eligible distance sales. A separate Italian VAT registration may not be needed for those sales alone.
Example 2: German seller with stock in Italy
A German seller joins a fulfilment programme and stock is stored in Italy. Sales from the Italian warehouse to Italian consumers are domestic Italian supplies. OSS does not replace the Italian VAT registration generally needed to manage these transactions.
Example 3: Non-EU seller importing into Italy
A US company sends goods in bulk to an Italian logistics warehouse, then sells them to Italian customers. This is not a simple IOSS direct low-value import model. The business should assess import VAT, customs, Italian VAT registration and possible fiscal representative requirements.
Example 4: Digital service provider selling subscriptions
A non-Italian software provider sells subscriptions to private consumers in Italy and other EU countries. Depending on the structure and the services supplied, OSS may simplify reporting of VAT due in the customer’s Member State. However, if the company also has Italian operations, employees, local contracts or B2B supplies, further analysis is needed.
Decision checklist: OSS or Italian VAT?
Before deciding that OSS is enough, a foreign business should answer a few operational questions:
- Are the customers private consumers, VAT-registered businesses, or both?
- Where are the goods physically located before the sale?
- Are any goods stored in Italy, including through FBA or third-party logistics?
- Are goods imported into Italy before being sold?
- Are the sales domestic Italian supplies or cross-border distance sales?
- Is the seller EU-established or non-EU established?
- Does the marketplace act as deemed supplier for some transactions?
- Are correct Italian VAT rates applied to each product category?
- Are records sufficient to support OSS declarations and local VAT positions?
If the answer to any of these questions is unclear, the seller should not rely on OSS as a blanket solution. A transaction-by-transaction review is usually the safest approach.

FAQs
Does OSS replace Italian VAT registration?
No, not always. OSS can cover eligible cross-border B2C transactions, but Italian VAT registration may still be required when goods are stored in Italy, domestic Italian supplies are made, goods are imported into Italy, or other local VAT obligations arise.
Can I use OSS if I store goods in Italy?
You may use OSS for eligible cross-border sales, but storage of goods in Italy can create local VAT obligations. Sales from Italian stock to Italian customers are generally domestic Italian supplies and may require Italian VAT registration.
Is OSS useful for Amazon FBA sellers?
Yes, OSS can be useful for eligible cross-border B2C sales. However, Amazon FBA sellers must check whether stock is stored in Italy. If Italian fulfilment stock is used, OSS alone may not be enough.
What is the difference between OSS and IOSS?
OSS is mainly for eligible intra-EU B2C supplies and certain services. IOSS is for distance sales of imported goods in consignments not exceeding EUR 150, shipped from outside the EU to EU consumers.
Do non-EU sellers need a fiscal representative in Italy?
If a non-EU seller needs an Italian VAT registration, a fiscal representative may be required unless the seller can use another identification route under the applicable rules. The answer depends on the seller’s country and structure.
Conclusion
OSS is one of the most useful VAT simplifications available to businesses selling across the EU. It can reduce administrative complexity, centralise reporting and avoid multiple VAT registrations for eligible B2C sales. But it is not a universal substitute for Italian VAT registration.
The practical distinction is simple: OSS helps where the transaction falls within the scheme; Italian VAT registration may still be required where the business has local Italian VAT obligations, especially stock in Italy, domestic supplies, imports, local operations or transactions outside the OSS scope.
For foreign companies selling into Italy, the safest approach is to map the supply chain before deciding on the VAT setup. The relevant questions are where the goods are located, who the customer is, how the goods move, who imports them, whether a marketplace is involved and whether any Italian domestic transaction takes place.
ISY can review your business model, fulfilment setup, customer flows and VAT position to determine whether OSS is sufficient or whether Italian VAT registration or fiscal representation is required.
