This guide explains EU VAT, IOSS and OSS for Amazon sellers and e-commerce businesses based outside the European Union — in the UK, US, Hong Kong, Australia or elsewhere. It covers when and where you need to register, how each mechanism works, the most common compliance mistakes, and what changes when your goods are stored in the EU rather than shipped directly from your home country.
VAT Basics
VAT (Value Added Tax) is a consumption tax applied to goods and services sold in the EU. The key point for non-EU sellers: VAT obligations follow the goods, not the seller. If you are selling to EU consumers — whether from inventory stored in the EU or shipped directly from outside — you are required to charge and remit VAT to the relevant EU tax authority. The rate varies by country: Germany 19%, France 20%, Poland 23%, Netherlands 21%. There is no minimum turnover threshold for non-EU sellers — the obligation applies from the first sale if you are storing goods in the EU.
At minimum, you need VAT registration in every EU country where you physically store inventory. For Amazon FBA sellers, this means every country where Amazon places your goods in its fulfilment centres. Using Pan-EU FBA typically triggers registrations in Germany, France, Italy, Spain, Poland and the Czech Republic. Single Country mode (Germany only) requires only German VAT registration. Beyond storage, you may also need registration if your cross-border sales to a specific EU country exceed the OSS threshold — though OSS simplifies this considerably. The EU market entry checklist covers which registrations to prioritise for first-time EU sellers.
Zero. Non-EU sellers have no minimum threshold — registration is required from the first sale if goods are stored in the EU. This is different from EU-to-EU sellers, who can use OSS and benefit from a €10,000 pan-EU threshold before cross-border VAT obligations kick in. As a non-EU seller storing goods in Germany, for example, you must be VAT-registered in Germany before your inventory arrives — not after your first sale. Start the registration process before your shipment departs origin.
VAT registration is the process of applying to a national tax authority to become a registered VAT taxpayer in that country. A VAT number is the unique identifier issued to you after registration is approved — it appears on your invoices and VAT returns. Each EU country issues its own VAT number in its own format (Germany: DE followed by 9 digits, France: FR followed by 11 digits). Getting a VAT number requires registration; registration timelines vary: Germany 4 to 8 weeks, France 4 to 6 weeks, Poland 2 to 4 weeks. You need one VAT number per country where you are registered.
IOSS Explained
IOSS (Import One-Stop Shop) is an EU VAT simplification mechanism for B2C sales of goods valued under €150 that are shipped directly from outside the EU to EU consumers. With IOSS, you register in one EU member state, collect VAT at the point of sale (at the buyer's country rate), and file a single monthly IOSS return covering all EU sales. The buyer pays no additional VAT at customs — the goods clear quickly because the VAT has already been declared. Without IOSS, customs collects VAT from your customer at delivery, causing delays, poor buyer experience, and sometimes double charging.
If your goods are stored in an EU FBA fulfilment centre, IOSS does not apply to those sales — Amazon handles VAT collection and remittance on FBA transactions through its marketplace facilitator rules. IOSS is only relevant if you are shipping individual parcels directly from outside the EU to EU consumers without first importing them into EU storage. Most FBA sellers import in bulk to an EU prep centre first — in that case, import VAT is paid at the EU border on the bulk shipment, and standard EU VAT (not IOSS) applies to individual consumer sales from FBA. See B2C and B2B fulfillment in Germany for how fulfilment structure affects your VAT position.
Non-EU sellers cannot register for IOSS directly — you must appoint an EU-established intermediary (a VAT agent or fiscal representative) to register on your behalf. The intermediary is jointly liable for your IOSS VAT obligations, so they will require a guarantee or deposit. Registration itself is free; intermediary fees typically run EUR 500 to EUR 2,000 per year depending on sales volume and the provider. You can register in any EU member state — many non-EU sellers use Ireland, the Netherlands or Germany. Once registered, you receive an IOSS number to provide to customs on each shipment.
If you store goods at a 3PL in the EU and ship to EU consumers from that EU location, those transactions are no longer subject to IOSS — they are standard domestic or intra-EU sales that use normal VAT registration and reporting. Your IOSS obligation remains only for any goods you continue to ship directly from outside the EU (for example, if you still have some direct-ship orders alongside your EU inventory). Many sellers start with direct shipping under IOSS and transition to EU storage as volume grows — at that point, IOSS becomes less relevant and standard EU VAT registration takes over entirely. B2C and B2B fulfillment in Germany explains how the transition affects your VAT structure.
OSS Explained
OSS (One-Stop Shop) simplifies VAT compliance for cross-border B2C sales of goods that are already within the EU. If you store goods in Germany and sell to a French consumer, you would normally need French VAT registration to account for French VAT. OSS removes that requirement: you register for OSS in one EU country (your choice), file a single quarterly return covering all your EU cross-border B2C sales, and pay all the VAT through that one registration. IOSS covers goods shipped from outside the EU under €150. OSS covers goods shipped from within the EU to consumers in other EU countries — a completely different scenario.
Yes. Non-EU sellers who have inventory stored in the EU can register for OSS in any EU member state. The most common choice is the country where you already have VAT registration (typically Germany for FBA sellers). OSS registration means you file one quarterly return instead of registering separately in each destination country for your cross-border B2C sales. However, OSS does not replace the VAT registration required in the country where you store goods — you still need German VAT registration if your goods are in Germany. OSS only simplifies the reporting of sales to consumers in other EU countries.
OSS covers B2C sales of physical goods shipped from one EU country to consumers in a different EU country. It does not cover: B2B sales (these use reverse charge), sales to consumers in the same country where goods are stored (these use your standard domestic VAT registration), sales of goods shipped from outside the EU (these may fall under IOSS), or marketplace transactions where the marketplace itself is the deemed supplier under EU marketplace facilitator rules — which applies to most Amazon FBA sales. For Amazon FBA sellers, OSS is most useful for sales through your own website or non-Amazon channels where you are the supplier of record.
Registration Process
Timeline varies significantly by country: Germany 4 to 8 weeks (Finanzamt process, requires certified translations and often a fiscal representative), France 4 to 6 weeks (Direction Générale des Finances Publiques, similar requirements), Poland 2 to 4 weeks (fastest of the major FBA markets). All typically require certified translations of your company registration documents, and some require an apostille. The practical advice: start registration at least 8 weeks before your first inventory is due to arrive in that country. Do not wait until the goods are in the air. See the shipping to Amazon EU FBA guide for the full inbound preparation timeline.
It depends on the country. Germany and France require non-EU companies to appoint a fiscal representative — an EU-established entity that is jointly liable for your VAT obligations. This is different from a VAT agent (who files on your behalf but bears no liability). Fiscal representative fees typically run EUR 500 to EUR 2,000 per year. Poland does not require a fiscal representative for non-EU companies. The Netherlands and Ireland are also straightforward for non-EU registration without mandatory representation. When choosing which EU country to register in first, the fiscal representative requirement and cost is a practical factor worth considering.
Yes. Amazon offers VAT Services through Seller Central, connecting sellers with third-party VAT providers who handle registration and ongoing filing. It covers Germany, France, Italy, Spain, Poland and the Czech Republic. The service is convenient for sellers starting out and integrates with your Amazon sales data. Costs vary by provider and country — typically EUR 400 to EUR 800 per country per year for basic registration and quarterly filing. The limitation: Amazon's VAT Services covers Amazon channel transactions well but may not cover your full VAT position if you also sell through Shopify or other channels. Review scope carefully before committing.
B2B vs B2C VAT
B2C (selling to consumers): you charge VAT at the buyer's country rate and remit it to that country's tax authority — either directly through a local VAT registration or via OSS. The consumer pays the gross price including VAT. B2B (selling to businesses): if the buyer is VAT-registered in another EU country, the reverse charge mechanism applies — you issue an invoice without VAT, the buyer accounts for VAT in their own country, and no VAT changes hands between you and the buyer. B2B sales within the same country follow normal domestic VAT rules — you charge VAT, buyer reclaims it. The key practical step: always verify the buyer's EU VAT number via the EU VIES system before applying reverse charge.
Reverse charge is a VAT accounting mechanism for cross-border B2B transactions within the EU. Instead of the seller charging VAT, the buyer self-accounts for VAT in their own country. It applies when: the seller and buyer are both VAT-registered, the transaction is a cross-border B2B supply of goods or services within the EU, and the buyer provides a valid EU VAT number. It does not apply to B2C sales, to sales where the buyer cannot provide a verified VAT number, or to domestic sales within the same country. On the invoice, state 'VAT: reverse charge — Article 194 of EU VAT Directive' and include the buyer's VAT number. Failure to verify the buyer's VAT number before applying reverse charge leaves the seller liable for the VAT.
Common Mistakes
The five most costly mistakes: (1) starting to sell before obtaining a VAT number — tax authorities can assess back-tax with penalties and interest from the first sale; (2) applying IOSS to goods already stored in the EU — IOSS only applies to direct cross-border shipments from outside the EU, not to FBA sales; (3) applying reverse charge without verifying the buyer's VAT number via VIES — if the number is invalid, the seller owes the VAT; (4) not filing nil returns — VAT filing deadlines apply even if you have zero sales in that period, and missed nil returns generate automatic penalties; (5) ignoring Pan-EU FBA VAT triggers — enrolling in Pan-EU without registering in all the countries where Amazon places your inventory creates significant retrospective liability.
Amazon withholds VAT from your disbursements in countries where you should be registered but are not. The relevant tax authority can assess retrospective VAT on all sales from the date registration was required, plus late payment interest (Germany: 1.8% per year) and potentially penalties. In Germany, sustained non-registration can be treated as tax evasion — a criminal offence for the responsible person. Amazon may also suspend your selling privileges if it identifies unresolved VAT compliance issues. The retrospective liability grows with every month of continued selling without registration — starting registration immediately is always cheaper than the accumulated assessment.
In the EU, consumer-facing prices must be displayed inclusive of VAT — the gross price includes VAT. When you set your Amazon selling price, that price is the gross price; Amazon calculates the VAT component and remits it on your behalf for FBA transactions. Your net revenue is the gross price minus VAT minus Amazon fees. When building your margin model, always work from the net price (gross minus VAT) to understand your actual per-unit revenue. The VAT rate applied depends on the product category and destination country — standard rates apply to most consumer goods, but reduced rates apply to certain food, books, and other categories.
Filing and Compliance
Filing frequency varies by country and sometimes by your VAT liability level. Germany: monthly if annual liability exceeds EUR 7,500, otherwise quarterly; annual return required regardless. France: quarterly for most sellers, monthly for large taxpayers. Poland: monthly. OSS returns: quarterly, covering all EU cross-border B2C sales. IOSS returns: monthly. The critical rule: filing deadlines apply even if you have zero sales — a nil return must be filed on time or you incur penalties. Missing filing deadlines even for nil periods is one of the most common and easily avoided compliance failures. Set calendar reminders for every filing deadline in every country where you are registered.
