What is Sales Tax?
- Definition: A consumption tax imposed on the sale of goods and certain services, collected at the point of sale.
- Who pays? Consumers pay the tax, but businesses are responsible for collecting and remitting it to the state.
- Scope: Applies to retail sales to end consumers. Wholesale transactions (resales) are generally exempt.
History of Sales Tax in the USA
- 1921: West Virginia introduces the first modern sales tax.
- 1930s: Widespread adoption during the Great Depression as states sought revenue.
- Today: 45 states and the District of Columbia impose a statewide sales tax. Five states (Alaska, Delaware, Montana, New Hampshire, Oregon) do not levy a state sales tax, though some allow local taxes.

- Purpose: Prevents consumers from avoiding tax by buying across state lines.

Sales Tax and E-Commerce
The 2018 Supreme Court case South Dakota v. Wayfair changed the landscape:
- States can require online sellers to collect sales tax even without physical presence.
- Thresholds: Typically $100,000 in sales or 200 transactions in a state.
- Result: Most online purchases now include sales tax.
Business Compliance
Businesses must:
- Register for a sales tax permit in each state where they have nexus.
- Collect the correct tax rate at the point of sale.
- File returns (monthly, quarterly, or annually).
- Remit payments to the state.
Failure to comply can result in penalties, interest, and audits.

Sales Tax Nexus
Nexus = sufficient connection to a state requiring tax collection.
Types of nexus:
- Physical nexus: Office, warehouse, employees.
- Economic nexus: Sales thresholds (post-Wayfair).
- Affiliate nexus: Using third-party affiliates in a state.
- Click-through nexus: Online referrals from in-state websites.
Filing and Reporting
- Frequency: Monthly for large businesses, quarterly or annually for smaller ones.
- Returns: Must detail taxable sales, exempt sales, and tax collected.
- Audits: States may audit businesses to ensure compliance.
International Perspective
- USA: No federal sales tax, state/local variation.
- Europe: Uses VAT (Value-Added Tax), applied at each stage of production.
- Canada: Uses GST/HST, a hybrid federal-provincial system.
Key difference: VAT is collected throughout the supply chain, while U.S. sales tax is collected only at final sale.
Future Trends in Sales Tax
- Digital goods & services: Increasingly taxed (e-books, streaming, SaaS).
- Marketplace facilitators: Platforms like Amazon and eBay required to collect tax on behalf of sellers.
- Automation: Businesses adopting tax software (Avalara, TaxJar) for compliance.
- Policy debates: Some states exploring replacing income tax with higher sales tax.
