Navigating US Sales Tax: Combined Rates, Economic Nexus, and Exemptions
Unlike many international nations that employ a centralized national Value-Added Tax (VAT), the United States relies on a decentralized, dual-tier sales and use tax framework. Sales tax is governed at the state and municipal levels rather than the federal level. Consequently, there is no federal sales tax in the US; instead, 45 states plus the District of Columbia levy statewide sales taxes, with thousands of local counties, municipalities, and special transit districts assessing piggybacked local surtaxes.
Five states—frequently remembered by the acronym NOMAD (New Hampshire, Oregon, Montana, Alaska, and Delaware)—do not impose a statewide sales tax. However, Alaska permits local municipalities and boroughs to levy localized sales taxes ranging up to 7.5%. Conversely, states like California, Tennessee, and Louisiana feature combined state and local rates that frequently exceed 9% to 10% in high-density metropolitan commercial hubs.
The landmark 2018 Supreme Court ruling in South Dakota v. Wayfair fundamentally reshaped eCommerce taxation through economic nexus. Prior to Wayfair, retailers were only obligated to collect sales tax in states where they maintained a physical footprint (such as an office, warehouse, or storefront). Today, online sellers who surpass state-specific economic thresholds (typically $100,000 in gross revenue or 200 separate transactions) must register and remit destination-based sales tax regardless of physical presence.
Product categorization plays a major role in sales tax calculations. Essential necessities—such as unprepared grocery food items and prescription pharmaceuticals—are exempt from sales tax or subject to reduced rates across a large majority of states. Furthermore, business-to-business transactions involving goods acquired strictly for manufacturing incorporation or inventory resale can claim exemption by providing a valid resale certificate.

In origin-based states, sales tax is charged based on where the seller is located. In destination-based states (the majority of states), sales tax is charged based on where the buyer receives the product.
Most states exempt unprepared grocery foods from sales tax or tax them at a substantially reduced rate, while prepared hot meals from restaurants are almost universally taxable.
A resale certificate is a legal document provided by retailers to wholesalers certifying that purchased goods will be resold to consumers, exempting the initial wholesale purchase from sales tax.
Under South Dakota v. Wayfair, states can require out-of-state online retailers to collect and remit sales tax once they exceed economic nexus thresholds (usually $100,000 in sales or 200 transactions annually).
