The Complete US Sales Tax Guide (2026): Rates, Nexus & How to Save

Sales tax is one of the most misunderstood costs in American commerce. The United States has no federal sales tax — instead, 45 states plus the District of Columbia levy their own sales taxes, and most let cities and counties add local taxes on top. The result is more than 13,000 separate sales-tax jurisdictions, each with its own rate and rules.

This guide explains how US sales tax works in 2026, how rates differ by state, when remote sellers must register (economic nexus), what goods and services are taxable, and — most importantly — how to calculate and legally reduce the sales tax you pay.

How US Sales Tax Works

Sales tax is a consumption tax charged at the point of sale. Two features make it complicated:

• It is stacked. A typical purchase carries a state rate plus a local (city/county) rate, producing a "combined" rate. California's state rate is 7.25%, but local add-ons push the combined rate in some cities to 11.5%.
• It is destination-based (mostly). For online and out-of-state sales, the tax is generally based on the ship-to address (where the buyer receives the goods), not where the seller is located. For in-store sales, it is based on the store's location.

Economic Nexus: When Remote Sellers Must Collect (2026)

Before 2018, only sellers with a physical presence (office, warehouse, employees) in a state had to collect its sales tax. That changed with the Supreme Court's Wayfair decision, which let states require tax collection based purely on sales volume — called economic nexus.

In 2026, 45 jurisdictions enforce economic nexus. The standard threshold is $100,000 in annual in-state sales, but the map is far from uniform:

• $500,000: California, Texas, New York
• $250,000: Alabama, Mississippi
• $100,000 (standard): most other states
• 200-transaction test: 18 states still trigger nexus at 200 separate transactions even if sales are below $100,000 — a trap for low-price sellers.

Two states use an AND test: New York requires $500,000 and 100 transactions; Connecticut requires $100,000 and 200 transactions. Everywhere else, either condition alone is enough.

What Is Taxable? Goods, Services, Food, and Clothing

There is no single national rule — each state decides:

• Tangible goods are taxable in almost every state that has sales tax.
• Services are taxable in some states (e.g., New Mexico, Hawaii, South Dakota) but exempt in most.
• Grocery food is exempt or reduced-rate in many states; Tennessee and Mississippi tax it fully.
• Clothing is tax-free in Delaware, New Hampshire, Oregon, Montana, and generally Pennsylvania, but fully taxed in New York and California.

Because rules vary, always verify the specific item in the buyer's state using our sales tax calculator.

Sales Tax Holidays in 2026

Many states suspend sales tax for limited periods to encourage spending:

• Florida — back-to-school (late July: clothing under $100, supplies under $50, computers under $1,000) and hurricane-prep (May to June). See our Florida tax-free shopping guide.
• Texas — back-to-school and energy-efficient appliance holidays.
• Several other states run annual weekend holidays.

How to Calculate and Legally Reduce Sales Tax

1. Calculate the exact rate

Our sales tax calculator combines state and local rates for any address in seconds.

2. Use a tax-free billing address (for online purchases)

Merchants charge sales tax based on your billing address. Using a tax-free state address — especially Delaware, which has the highest AVS pass rate — legally eliminates sales tax on digital goods, subscriptions, and many online orders. Our step-by-step tutorial shows how.

3. Buy during tax-free holidays

Time large purchases to your state's holiday weekends.

4. Shop in lower-rate jurisdictions

A $2,000 item costs about $27 more in Los Angeles (10.25%) than in San Francisco (8.875%).

This is legal tax avoidance, not evasion. For the full playbook, see how to legally avoid sales tax online.
