U.S. Sales Tax Explained for Germany-Based Companies
Why sales tax is important: U.S. sales tax is a consumption tax imposed on retail sales of goods and some services. Unlike Germany’s Value-Added Tax (VAT), which applies at each stage of production and is federally regulated, U.S. sales tax is:
- State-level: Set and administered by individual states, not the federal government.
- Retail-only: Charged only at the final point of sale to the consumer.
- Rate variability: Rates differ by state, county, and city, leading to combined rates that vary widely.
Below is a comparison between Germany’s VAT vs Sales tax:
| Aspect | U.S. Sales Tax | Germany VAT (Mehrwertsteuer) |
|---|---|---|
| Governing Level | State and local governments | Federal government (EU-harmonized) |
| Tax Rate | Varies | 19% (standard rate), 7% (reduced rate) |
| Tax Application | Only on final retail sales | At every production and distribution stage |
| Who Collects? | Seller | Businesses at each supply chain stage |
U.S. Sales Tax Explained for Germany-Based Companies
Germany-based businesses must pay U.S. sales tax if they meet economic nexus thresholds in any U.S. state. These thresholds typically require either:
- A certain amount of sales revenue (often $100,000 or more annually) or
- A minimum number of transactions (commonly 200 or more per year).
The rules apply whether you sell through your website, third-party platforms like Amazon or Shopify, or wholesale channels. Both physical goods and digital services (including SaaS) may trigger tax obligations, depending on state laws.
