California levies the highest state-level base sales tax rate at 7.25%, followed by Indiana, Mississippi, Rhode Island, and Tennessee at 7.00%. When average county and city local sales taxes are added, the highest combined statewide averages are in Louisiana (~9.55%), Tennessee (~9.55%), Arkansas (~9.43%), Washington (~9.17%), and Alabama (~9.14%).

To add sales tax to a pre-tax price, multiply the price by the decimal tax rate: on an $899 laptop at 9.75% combined tax, Sales Tax = $899 × 0.0975 = $87.65, and Total Price = $986.65. To reverse-calculate the pre-tax price from a tax-included receipt total, divide the total by (1 + tax rate): on a $108.00 receipt at 8% tax, Pre-Tax Price = $108 ÷ 1.08 = $100.00, and Sales Tax = $8.00.
All 50 states exempt prescription medications from sales tax, and 37 states plus Washington, D.C. completely exempt unprepared grocery food.

Wayfair ruling, all 45 states with a statewide sales tax enforce 'economic nexus' rules—requiring out-of-state online retailers and marketplace facilitators (Amazon, eBay, Shopify, Etsy) that exceed state volume thresholds (typically $100,000 in annual gross sales) to collect and remit the buyer's exact destination state and local sales tax at checkout.
US sales tax is charged only once at the final retail point of sale to the end consumer; wholesalers and resellers buy inventory tax-free using a state Resale Certificate. Use tax is the mirror-image tax owed by a buyer directly to their home state when purchasing taxable equipment or goods from an out-of-state vendor that did not collect sales tax. Value Added Tax (VAT), used in the UK, EU, and 170+ countries, is collected fractionally at every stage of production and sold tax-inclusive.
