State Sales Tax Rates: What You Need to Know
Sales tax is a percentage added to most purchases at checkout. Unlike income tax, which is based on what you earn, sales tax is based on what you buy—and the rate you pay depends entirely on where you're making the purchase.
Understanding how state sales tax works matters because it directly affects your total cost, and the rules vary significantly across the country. This guide explains how these rates are structured, what influences them, and what factors shape how much tax you'll actually pay. đź“Š
How State Sales Tax Works
When you buy something in a store or online, a percentage of that purchase goes to your state (and sometimes your local government). That percentage is the sales tax rate. A state with a 6% sales tax means that a $100 purchase costs $106 at checkout.
Important distinction: Not all states have sales tax. Five states—Alaska, Delaware, Montana, New Hampshire, and Oregon—have no statewide sales tax. (Alaska does allow local sales taxes, and New Hampshire taxes certain services.) The remaining 45 states each set their own statewide rate.
What Determines Your Sales Tax Rate?
Your actual tax rate depends on several factors:
State Rate
Each state that collects sales tax sets a base rate. These rates typically range from around 4% to 7.25%, though this varies and can change.
Local Jurisdictions
Many cities, counties, and districts add their own sales tax on top of the state rate. This is why two locations within the same state can have different total tax rates. Your total rate = state rate + local rate(s).
What You're Buying
Sales tax doesn't apply uniformly. Most states exempt certain items—commonly groceries, prescription medications, and medical devices—while taxing others at full rate. Some states tax clothing or services differently. These exemptions vary significantly by state.
Who's Selling
For years, online sellers only had to collect sales tax if they had a "physical presence" in a state. That changed after the 2018 Supreme Court decision South Dakota v. Wayfair, which gave states broader authority to require online collection. Today, rules are still evolving, and different states apply them differently.
The Spectrum of State Sales Tax Rates
| Rate Level | Approximate Range | What This Means |
|---|---|---|
| No state sales tax | 0% | Five states; local taxes may still apply |
| Lower state rates | 4%–5% | Plus any local additions |
| Mid-range state rates | 5%–6% | Most common range nationally |
| Higher state rates | 6%–7.25% | Often with additional local taxes |
Combined rates (state + local) can exceed 10% in some areas, while others total closer to 4–5%.
What You Should Know Before You Shop or Move
Tax applies to most goods, but not everything. Groceries, medicine, and medical equipment are commonly exempt, but each state decides. If you're budgeting or relocating, research what's taxed in your specific location.
Online shopping follows new rules. Major retailers now collect sales tax in most states, even if they don't have a store there. Smaller sellers have different obligations depending on state size and thresholds.
Local rates change. Even if your state rate stays the same, city or county additions can shift. If you move within a state, your tax rate might change.
Services are treated differently. Haircuts, repairs, and professional services may or may not be taxable depending on your state.
Where to Find Your Actual Rate
Your combined sales tax rate (state + local) is set by your location. Retailers' websites often show you the tax before you complete a purchase. Your state's tax authority website will have the official statewide rate, though you'll need to confirm any local additions separately.
The key takeaway: Sales tax rates are not uniform across the country. They depend on your state, your city or county, what you're buying, and who's selling it. Understanding these variables helps you anticipate costs and make informed purchasing decisions.
