EU OSS & IOSS VAT Thresholds: A Complete 2026 Guide for Cross-Border Sellers
Written by: Huzaifa Aziz
The single most common misunderstanding in European e-commerce compliance is assuming that the EU-wide €10,000 distance-selling threshold applies universally to every seller. It does not. The €10,000 threshold applies exclusively to businesses established within one of the 27 EU member states. If your business is established outside the EU—whether in the United Kingdom, the United States, China, Canada, or Australia—you have no threshold whatsoever. Non-EU sellers are subject to EU VAT obligations from their very first B2C transaction into any EU member state.
This structural distinction creates two completely different compliance rulebooks depending on where your company is incorporated. Competitor guides frequently blur these lines, misleading international merchants into waiting for a €10,000 sales milestone that legally does not exist for them. This cornerstone guide breaks down the exact mechanics of the One Stop Shop (OSS), the Import One Stop Shop (IOSS), the marketplace deemed-supplier rules, and how to select the right registration pathway for your business model.
1. The €10,000 Threshold, and Who It Actually Applies To
Prior to July 1, 2021, each EU member state maintained its own national distance-selling threshold. A seller based in Germany could sell up to €35,000 into France, €100,000 into Italy, and €35,000 into Spain before having to register for local VAT in each of those destination countries. This created immense administrative friction, forcing growing merchants to hold upwards of a dozen local VAT registrations simultaneously.
The EU VAT E-Commerce Package dismantled this fragmented regime and replaced it with a single, simplified EU-wide cumulative threshold of €10,000. However, critical rules govern how this €10,000 figure is calculated:
- It is EU-wide cumulative, not per-country: You do not get €10,000 for France, another €10,000 for Germany, and another €10,000 for Spain. Sales across all 27 EU member states are aggregated into one single running total.
- It applies exclusively to EU-established sellers: You must maintain a physical business establishment or fixed establishment in an EU member state to qualify.
- It evaluates both current and prior calendar years: The €10,000 test does not "reset" on January 1st in isolation. If your cross-border sales exceeded €10,000 in the previous calendar year, you remain over threshold for the entirety of the current calendar year regardless of your running current-year total.
- Under €10,000: An EU seller may continue charging their domestic home-country VAT rate on all B2C cross-border sales and account for it via standard domestic VAT returns. Alternatively, they may voluntarily opt into Union OSS to charge destination rates early.
- Over €10,000: The seller must charge the specific destination country's standard VAT rate (e.g., 20% in France, 19% in Germany, 27% in Hungary) starting from the exact transaction that crosses the threshold. To report this without registering in 27 states, the seller registers for Union OSS in their home country.
2. Non-EU Sellers: Why There's No Threshold At All
Non-EU businesses (e.g., US LLCs, UK Ltds, Chinese exporters) operate under a strict zero-threshold regime. Article 59c of Council Directive 2006/112/EC explicitly restricts the €10,000 micro-business exemption to suppliers established within the Community territory.
Because a non-EU business does not collect or remit domestic VAT in an EU home state, the European Commission requires equal treatment across member states from dollar one. If a US Shopify merchant sells a single €25 T-shirt or a single €15 digital software license to a consumer in Munich, that sale is immediately subject to German VAT (19%).
Warning for Non-EU Merchants: Assuming you can sell up to €10,000 into the EU before addressing VAT is a compliance violation. Tax authorities in countries like Germany and France actively audit customs import records and payment processor filings (under CESOP regulations) to catch unregistered non-EU merchants.
3. OSS vs IOSS vs Local VAT Registration: The Decision Framework
Selecting the correct VAT scheme depends on three factors: seller establishment, product type (goods vs digital services), and consignment value. The framework below outlines the four primary compliance pathways under EU law:
| Scheme / Route | Eligible Seller Location | Covered Supply Type | Consignment Cap | Registration State |
|---|---|---|---|---|
| Union OSS | EU Member States only | Goods & Services (Cross-border B2C) | No cap | Home EU State of establishment |
| Non-Union OSS | Non-EU Sellers only | Digital & Telecom Services only | No cap | Any single EU Member State of choice |
| IOSS (Import OSS) | Both EU & Non-EU Sellers | Goods imported from 3rd territories | ≤ €150 per consignment | One EU State (via Intermediary if non-EU) |
| Local VAT Registration | Any seller holding local stock | Domestic sales from local warehouses | N/A | State where warehouse is located |
The €150 Consignment Cap for IOSS
The Import One Stop Shop (IOSS) applies strictly to commercial goods with an intrinsic consignment value of €150 or less. Intrinsic value excludes separate freight, insurance, and duty charges, provided those fees are separately itemized on the commercial invoice.
When goods exceed €150 per shipment, IOSS cannot be used. Instead, standard customs declaration procedures take over. Import VAT and customs duties are assessed at the border and must be paid by the customer upon delivery (DDU/DAP) or billed back to the merchant via an express carrier under Delivery Duty Paid (DDP) terms.
4. The Marketplace Deemed-Supplier Rule (Most Overlooked Edge Case)
Under Article 14a of the EU VAT Directive, online marketplaces (such as Amazon, Etsy, eBay, and AliExpress) are legally classified as "deemed suppliers" for specific transactions. When a marketplace acts as a deemed supplier, it is legally responsible for calculating, collecting, and remitting EU VAT to tax authorities—taking the burden off the individual merchant.
Why Marketplace Sales Must Be Excluded from Your Threshold
Because the marketplace remits VAT under its own OSS/IOSS registration for deemed-supplier sales, merchants must EXCLUDE those marketplace transactions from their own €10,000 threshold calculation. Counting marketplace sales toward your threshold creates a artificial inflation that triggers unnecessary OSS registrations.
Worked Example: Direct-to-Consumer + Amazon Sales
Suppose a French-established seller generates €7,000 in direct sales via their own Shopify store and €5,000 in sales via Amazon (where Amazon collects and remits VAT under deemed-supplier rules).
The merchant can continue charging French domestic VAT on Shopify sales because their eligible direct sales (€7,000) remain below the €10,000 limit.
5. Practical Walkthrough: Registering, Filing, and Staying Compliant
Operating under OSS or IOSS streamlines reporting into a single electronic quarterly return. Below are the essential administrative steps for maintaining full compliance:
Quarterly Filing Schedule
OSS returns are submitted electronically on a quarterly basis. The deadline is strict: the final day of the calendar month following the end of the quarter:
- Q1 (Jan 1 – Mar 31): Deadline 30 April
- Q2 (Apr 1 – Jun 30): Deadline 31 July
- Q3 (Jul 1 – Sep 30): Deadline 31 October
- Q4 (Oct 1 – Dec 31): Deadline 31 January
Recordkeeping & Audit Trail
Under Article 369k, businesses using OSS/IOSS must retain transaction records for a mandatory period of 10 years from the end of the year in which the transaction was carried out. Records must be made available electronically to tax authorities upon request.
6. Multi-Country Worked Example
Consider an EU seller established in Italy selling direct-to-consumer goods into three EU member states during 2026:
- March 2026: Ships €4,000 of goods to customers in France. (Running total = €4,000. Under threshold. Charge Italian VAT 22%).
- June 2026: Ships €4,500 of goods to customers in Germany. (Running total = €8,500. Under threshold. Charge Italian VAT 22%).
- August 2026: Ships €3,000 of goods to customers in Spain. (Running total = €11,500. Crossed threshold mid-year!).
Outcome: Starting with the Spanish transaction that pushes the total over €10,000, the seller must apply destination VAT rates (Spanish 21% VAT for Spain, German 19% for Germany, French 20% for France) and submit a Q3 Union OSS return to the Italian tax authorities.
