Why This Matters For EU Sellers
EU ecommerce sellers selling into the United States — through Amazon FBA, Shopify, Walmart, Etsy or a branded site — face the same U.S. sales tax obligations as any other foreign or domestic seller. The U.S. has bilateral income tax treaties with most EU member states, but those treaties do NOT cover sales tax.
EU sellers come to U.S. sales tax with strong VAT literacy (much like UK sellers post-Brexit), but with one important difference: OSS (One-Stop-Shop) and IOSS (Import One-Stop-Shop) have no U.S. equivalent. There is no federal U.S. VAT system, no central registration. Each of 45 U.S. states runs its own sales tax with its own rules, rates, thresholds and registration mechanics.
This guide walks EU sellers through what to do — registration, banking, payment, currency, and the structural choices that make compliance manageable from Berlin, Paris, Amsterdam, Milan, Madrid, Warsaw or Dublin.
Yes, You Owe US Sales Tax. EU-US Tax Treaties Don’t Cover It.
The U.S. has individual income tax treaties with most EU member states — Germany, France, the Netherlands, Italy, Spain, Belgium, Sweden, Denmark, Ireland, Austria, Finland, Greece, Hungary, Luxembourg, Portugal, Czech Republic, Poland and others. These treaties are robust on income tax: they prevent double taxation of business profits, define permanent establishment, and provide reduced withholding rates.
None of them cover U.S. state sales tax. Sales tax is a state-level transaction tax, not federal income tax. Treaty protection on profits doesn’t reduce sales tax obligations.
The 2018 Wayfair decision means all 45 U.S. states with sales tax now apply economic nexus rules to remote sellers — including EU residents. Thresholds run from $100,000 (most states) to $500,000 (California, Texas, New York). EU companies are not exempt.
How U.S. Sales Tax Differs From EU VAT (and OSS/IOSS) — In Plain English
EU sellers will spot the differences immediately:
- No central registration. OSS lets you register once in one EU member state and report sales across all 27. The U.S. has no equivalent — you register separately with each state DOR.
- No federal layer. EU VAT has both an EU-level framework and member-state implementation. U.S. sales tax exists ONLY at state and local level — there is no U.S. federal VAT or sales tax.
- State-by-state rates and thresholds. 45 different rates, 45 different economic nexus thresholds, 45 different filing schedules.
- No input credit. Unlike VAT, U.S. sales tax has no equivalent of the VAT input credit. It’s a single-stage retail-only tax. B2B sales typically exempt with a resale certificate.
- Origin vs destination sourcing. Most states use destination sourcing (rate at the buyer’s location) but a few are origin-based.
- Local taxes on top of state rates. Many states have county, city and special-district taxes on top of the state rate — sometimes pushing combined rates above 10%.
- Physical presence creates instant nexus. Storing inventory in a U.S. state (Amazon FBA) creates immediate registration obligation, regardless of revenue. There’s no EU-style ‘reverse charge’ that shifts the obligation to the customer.
The Three Most Common Triggers for EU Sellers
1. Amazon FBA inventory in U.S. fulfillment centers
If you ship into Amazon US FBA, your inventory will be stored across 8–25 U.S. states. Each creates physical nexus, regardless of revenue.
2. Direct Shopify or branded site sales
Once your direct sales cross the economic threshold in a state ($100,000 in most), you must register, collect and remit.
3. EU-fulfilled orders into the U.S.
Some EU sellers ship directly from EU 3PLs (Amazon EU-FBA cross-border, DHL eCommerce, Asendia) to U.S. customers. This avoids U.S. physical nexus from inventory storage. You still owe sales tax in any state where direct sales exceed the economic threshold, but you avoid the FBA-inventory-everywhere trap. The downside is shipping cost and time.
How To Set Up From the EU
- Decide your structure. For U.S. sales under ~€250K/year, registering as your existing EU entity (German GmbH, French SAS, Dutch BV, Italian Srl, Spanish SL, etc.) is fine. For higher volumes, forming a U.S. LLC owned by your EU entity gives you simpler banking, less FX friction, and clearer customer trust.
- Get a U.S. EIN. Call IRS at +1-267-941-1099 (M–F 6am–11pm Eastern = M–F 12pm–5am Central European Time). Apply by phone with Form SS-4 in front of you. Write ‘FOREIGN’ in the responsible party’s SSN field. EIN issued on the call.
- Open Wise Business (without U.S. LLC) or Mercury / Brex / Relay (with U.S. LLC). All provide U.S. routing/account numbers for ACH payment to state DORs.
- Register for sales tax in your nexus states. Most states accept your EU business address. You’ll need EIN, formation documents (handelsregister extract, K-bis extract, KvK extract, etc.), passport copy and NAICS code (typically 454110).
- Configure Amazon, Shopify and Walmart with your state registration numbers.
- File and remit on each state’s cadence.

Currency, GDPR and Other EU-Specific Considerations
Currency: EUR–USD
EU sellers benefit from a deep, stable EUR–USD market. Conversion costs are low. Wise Business and Mercury both support EUR holding and conversion alongside USD. Match your tax-calculation currency to your remittance currency (USD throughout the period; convert to EUR for EU statutory accounts at period-end).
GDPR vs U.S. data
Sales tax registration with U.S. state DORs requires you to provide business identification data (name, address, EIN, responsible officer’s passport). This is a routine data transfer to a state government for tax purposes — covered by the legitimate-interest basis under GDPR. No special data transfer impact assessment is typically required.
OSS/IOSS — irrelevant to U.S. sales tax
OSS and IOSS are EU systems for VAT on intra-EU and import sales. They have no U.S. equivalent and no overlap. Your OSS or IOSS registration doesn’t help with U.S. sales tax.
Avoiding double-taxation thinking
EU sellers sometimes worry that paying U.S. sales tax means double-taxation. It doesn’t — U.S. sales tax is paid by the U.S. consumer (collected by you on their behalf). It’s a charge on top of your selling price, not a deduction from your margin (assuming you don’t absorb it). The buyer pays $109.50 for a $100 product in Texas (8.25% combined). The $9.50 belongs to the state, not to you.
Frequently Asked Questions
1. Can my German GmbH / French SAS / Dutch BV / Italian Srl register for U.S. sales tax directly?
Yes. U.S. states accept sales tax registration from foreign entities using your home-country business address. You’ll need a U.S. EIN, your formation documents (handelsregister extract for Germany, K-bis for France, KvK extract for Netherlands, visura camerale for Italy, escritura for Spain), a passport copy of the responsible officer, and a NAICS industry code (typically 454110).
2. Do I need to comply with both EU VAT (OSS/IOSS) AND U.S. sales tax for U.S. sales?
No — these are separate systems for separate jurisdictions. EU VAT (and OSS/IOSS) applies to intra-EU sales and EU imports. U.S. sales tax applies to U.S. sales. Selling from the EU into the U.S. typically incurs only U.S. sales tax (and U.S. customs duties on the import side, payable by the importer-of-record). You don’t owe EU VAT on a sale to a U.S. customer.
3. How does GDPR affect data shared with U.S. state DORs?
Standard sales tax registration data (business name, address, EIN, responsible officer ID) is shared with U.S. state governments for tax administration purposes. This is a legitimate-interest data transfer under GDPR Article 6(1)(f) and a public-interest transfer under Article 49(1)(d). No DPIA is typically required for routine tax compliance data sharing.
4. Should I form a U.S. LLC or just register as my EU entity?
For U.S. sales under ~€250K/year, registering as your EU entity is fine. For higher volumes, a U.S. LLC owned by your EU entity offers easier U.S. banking (Mercury, Brex, Relay), simpler customer trust signals, and easier expansion. Tax-wise, a single-member U.S. LLC owned by an EU entity is typically a disregarded entity for U.S. federal income tax — pass-through treatment with no double taxation.
5. How much will Sales Tax Compliance USA cost me as an EU seller?
Flat-fee pricing based on your nexus footprint, sales volume and channel mix. A typical EU Amazon FBA seller registered in 10–15 states pays a fixed monthly fee covering all registrations, ongoing filings, remittance and audit support. We quote a fixed price upfront. Book a free consultation and we’ll scope your project and quote within 24 hours.
EU Sellers, the U.S. Doesn’t Have OSS
The conceptual gap most EU sellers underestimate is the absence of any central U.S. system. There’s no U.S. equivalent of OSS, IOSS, or even a federal VAT to anchor your registration. Each of 45 states is its own jurisdiction with its own rules. The good news: that complexity is exactly what we exist to handle for you.
