US Sales Tax Guide for Brazil-Based Businesses

If your Brazil-based business sells goods or services in the U.S., understanding U.S. sales tax for Brazil businesses is essential for compliance. Unlike Brazil’s VAT system, U.S. sales tax operates at the state level, with varying rates and regulations across 45 jurisdictions. For Brazilian e-commerce sellers, SaaS providers, and digital service companies, compliance becomes mandatory when reaching specific sales thresholds – even without a physical presence in the U.S.

This sales tax guide provides Brazil-based businesses with clear, actionable information about U.S. sales tax obligations. You’ll learn how economic nexus rules apply to your operations, which states require tax collection on digital products, and the exact steps for registration and compliance.

Understanding U.S. Sales Tax as a Brazil-Based Seller

Unlike Brazil’s Value-Added Tax (VAT) system, which applies at each production stage, U.S. sales tax is a consumption tax imposed only on the final retail sale of goods and some services.

It is governed at the state level, meaning rates and rules vary across the U.S. Some states have no sales tax, while others impose rates between 4% and 11%. Local jurisdictions (counties and cities) may add additional taxes, creating further variations.

Key Differences Between Brazil’s VAT vs Sales tax:

Do Brazil Sellers Pay U.S. Sales Tax?

Brazil-based businesses may need to pay U.S. sales tax if they meet certain thresholds. Unlike Brazil’s tax system, where VAT applies broadly, U.S. sales tax for Brazil businesses depends on whether you establish a tax obligation, known as nexus, in a U.S. state. There are two types of nexus: economic and physical nexus.

Key Factors Determining Tax Obligation

1. Economic Nexus Thresholds – Most states require tax collection if your sales exceed the following:
   • $100,000 in revenue or
   • 200 transactions annually in that state.
2. Types of Businesses Affected – Applies to:
   • E-commerce sellers (physical goods)
   • Digital product providers
   • SaaS companies
3. Sales Channels – Whether you sell via:
   • Your website (Shopify, WooCommerce)
   • Online marketplaces (Amazon, eBay)
   • B2B or wholesale transactions

Marketplace facilitators (like Amazon) often handle tax collection, but if you sell through multiple channels, Brazil sales tax rules for U.S. sales may still require direct compliance.
