U.S. Sales Tax for Germany-Based Businesses is likely complex- and certainly cumbersome- especially for someone accustomed to Germany’s VAT system. The growth potential is tremendous when considering expansion into the U.S. market. This guide is aimed at German corporations selling products or services to customers in the United States. We will examine the structure of the sales tax system in the U.S., compare it with VAT in Germany, discuss concepts such as nexus, taxability, rates, registration, collection, filing, specific rules for SaaS, and how much easier compliance becomes with automated solutions like Commenda.
Introduction
Germany’s Mehrwertsteuer (VAT) system features a unified federal tax rate (19% standard, 7% reduced) that is charged at every stage of production and distribution, with full input-tax credits available. Sales and use tax is levied in the U.S. only at the last stage of sale to the end consumer, and it is administered at the state level, plus by thousands of local jurisdictions. For Canada-based businesses, this means:
Fragmentation: More than 45 states + DC have over 13,000 unique taxing jurisdictions, all with their own rates, rules, and filing calendars.
No input credits: U.S. sales tax paid on purchases cannot be offset against sales tax collected.
Point-of-sale focus: The location where possession of goods is handed over, not along the supply chain, is where tax is levied.

Understanding U.S. Sales Tax
U.S. sales tax, as the name suggests, is a tax levied on consumption, specifically a retail sale of goods and certain services in select states. It is the vendor who collects the tax from the retail customer, which is then paid over to the relevant state or local authority.
A few important differences with the German VAT:
- Tax Base: Only final retail sales vs every business stage in VAT.
- Jurisdictional Authority: State departments of revenue vs Federal Central Tax Office.
- Rates: Vary dramatically from 0% in Oregon to parts of Louisiana, where some parts exceed 10% combined.
- Exemptions: States may exempt food, clothing, or digital goods based on local policy.
Comparison: U.S. Sales & Use Tax vs. Germany’s VAT
| Feature | U.S. Sales & Use Tax | German VAT (Mehrwertsteuer) |
| Level of Governance | State & local | Federal |
| Standard Rate | Varies: 4–10% (combined) | 19% standard, 7% reduced |
| Input Tax Credit | None | Full credit at each stage |
| Taxable Transactions | Final retail sale only | All business stages |
| Filing & Payment | State-specific frequencies & due dates | Monthly or quarterly federal filings |
| Exemptions | Basic groceries, prescription drugs, some services (varies by state) | Medical, education, exports |
Why It Matters For German Businesses
If you ship products from Germany to US customers or host servers in the US for a cloud service, you must navigate:
Destination-based taxation: A customer’s shipping/usage address determines the tax rate.
Use tax liabilities: If you don’t collect tax, your customer may owe “use tax,” but enforcement is lax; however, liability still rests with you if nexus exists.
Local variations: A single ZIP code can straddle multiple tax jurisdictions with varying combined rates.
Do German Sellers Pay US Sales Tax?
German sellers only need to collect U.S. sales tax if they have established nexus in a given state. Nexus can be:
- Physical Nexus:
- Inventory held in U.S. warehouses (e.g., Amazon FBA, 3PL)
- Offices, employees, and trade-show booths within the U.S.
- Centers for the physical returns to customers
- Economic nexus U.S. sales tax Germany
- $100,000 in sales OR
- 200+ sales transactions to different customers from a single location each calendar year (varies by state)
Examples
- A Bavarian toy manufacturer fulfills 250 orders and ships out €90,000 worth of goods into Texas: economic nexus in Texas- must register, collect, and remit.
- A Munich SaaS company selling subscriptions to 150 customers from the United States, worth a total of $120,000, likely triggers economic nexus in most states.
- An Amazon FBA seller based in Hamburg, California, has inventory in California warehouses: a physical nexus in California for Amazon FBA users.
After the nexus has been established:
- Register with the particular state’s revenue department.
- Collect the correct sales tax at the designated checkout.
- Submit the tax and file periodic returns to the appropriate agency.
Economic Nexus and Sales Tax Rules for German Businesses
Economic Nexus: What Is It?
A business is bound to a taxing authority based on a set sales volume or number of transactions and not physical presence. Most states abide by the ‘$100,000 or 200 transactions’ approach, with some differences:
- Threshold Differences
- South Dakota: $100k or 200 transactions
- New York: $500K and 100 transactions.
- Washington: $100k and no transaction limit.
- Look-back Periods
- Some states use sales from the previous year as a benchmark for determining the current year’s nexus.
- Others, such as Massachusetts, use trailing twelve-month figures.
- Marketplace Facilitator Laws
- Some platforms like Amazon and eBay collect and pay taxes on behalf of the sellers, meaning those sellers are still required to register and submit returns.
Tracking and Evaluating Nexus
The Germany-based companies ought to:
- Sum up sales for the US by state using your ERP, marketplace, and payment processors.
- Track Transaction Counts to identify the 200-order threshold.
- Review quarterly to assess new nexus responsibilities.
Commenda and other tools can keep count of these limits in real time, warning users and even auto-enrolling in new states.
Tax Registration Requirements for Germany-Based Businesses in the U.S.
After establishing the states with nexus, take the following steps:
- Acquire a US taxpayer ID.
- Employer Identification Number (EIN) is ideal for businesses.
- Individual Tax Identification Number (ITIN) is for those who don’t have residency in America.
- Gather documentation
- Certificate of incorporation, German commercial register excerpts, proof of nexus activities (e.g., Amazon FBA reports).
- Register for Sales Tax Permits
- Access each state’s revenue department portal.
- Some states require notarized documents or U.S. agent service representation.
- Set up payment methods.
- U.S. bank account or international wire details (varies).
- Some states accept credit-card payment online; others require ACH.
- Obtain resale certificates
- If acquiring U.S. merchandise for resale, furnish resale certificates to suppliers so that you may not incur tax on wholesale purchases.
- Record keeping
- Keep 3-5 years of detailed sales and tax exemption documents per state law.
Example: Registering in California
- Step 1: Apply for EIN via IRS Form SS-4
- Step 2: Complete California CDTFA-400-SPA (out-of-state seller).
- Step 3: Provide Certificate of Good Standing from Germany’s Handelsregister.
- Step 4: Upload proof of economic nexus (sales reports).
- Step 5: Obtain California Sales Tax Permit (Reg. no. 123-456-789).
Collecting and Remitting U.S. Sales Tax
Setting up the collection
- Determine tax rates
- State rate + local city/county rates + special districts (e.g., transit, education).
- Example: Boulder, CO buyer: 2.9% (CO) + 1.185% (county) + 3.53% (city) + 1% (RTD) + 0.1% (SCFD) = 8.715%.
- Integrate a Tax Engine
- Custom carts, Shopify, and Magento can all be integrated with tax calculation engines like Commenda, Avalara, or TaxJar.
- Display Tax at Checkout
- Taxes must be shown on invoices due to tax law for reporting transparency.
- For B2B buyers, itemization by jurisdiction is available as an option. That is not the case with consumer buyers.
Remittance & Filing
- Payment Schedules: May be assigned by volume, so there are over $10K per month, quarterly, else it might fall below $1K annually.
- Due Dates: Less commonly, the 20th of the month after the reporting period; some use the 15th or 23rd.
- Filing Portals: Secure e-filing is recommended, but manual paper returns are still possible for some jurisdictions.
Example Flow for Texas
- Collect per ZIP code, 6.25% state plus local districts.
- Must 20th file form 01-114 monthly.
- Remit per WebFile portal using ACH debit and credit cards, or even by card.
- Maintain records of payment, returns, and exemption certificates.
Filing U.S. Sales Tax Returns from Germany
Filing from abroad has its share of challenges:
- Time Zone Coordination: U.S. portals close based on business hours.
- Zero Returns: States often require filing even with no taxable sales.
- Penalties: Late filing will always draw fines + interest. Several late filings can see permits suspended.
Best Practices:
- Centralized Calendar: Record all states’ due dates in CET.
- Automated Filing: Allow Commenda to e-file on your behalf.
- Language & Support: Access state portals in English; some provide limited support in German via phone.
Common Mistakes:
- Missing zero‑filing obligations.
- Filing under the wrong permit number.
- Incorrectly distinguishing between exempt vs taxable sales.
U.S. Tax Compliance for SaaS Businesses from Germany
The taxation of digital goods and SaaS is changing rapidly:
- States Taxing SaaS: New York, Texas, Minnesota, Tennessee, Washington, South Carolina, and others.
- States Exempting SaaS: California, Florida, Pennsylvania (under periodic review).
- Definition Differences: Some definitions include hosting, maintenance, and support, while others only include “electronically delivered software.”
Key Steps for SaaS Providers
- Define Taxability
- Research “digital goods” legislation for all applicable states.
- Determine if your business provides “off-the-shelf” solutions or customized offerings.
- Keep an Eye on Nexus
- SaaS subscriptions have the same economic thresholds.
- U.S.-based servers or CDNs may pose a physical nexus in some states.
- Collect & Remit
- SaaS and Consulting Revenue need to be separated for better tracking and analysis.
Germany Sales Tax Nexus in the USA: What It Means
German businesses will consider “Germany sales tax nexus in the USA” simply as incurring U.S. sales tax compliance obligation nexus triggers. Unlike Germany, where any sales within the EU are automatically VAT, the U.S. is state-specific:
- Physical vs. Economic. One needs a bricks & mortar tie and the other a sales cutoff.
- Foreign-Seller Provisions: Several states outright include remote sales of foreign sellers in their nexus statute.
- Marketplace Implications: You may have a filing obligation even if a tax is collected by Amazon.
Ignoring nexus can lead to unplanned audits, back tax calculations, and penalties that in many cases, are higher than the due payment.
