That $10 item rings up at $10.75 at the register. The extra 75 cents is sales tax. It’s easy to overlook because it’s built into every purchase — but it adds up. Over a year, the average American household pays thousands of dollars in sales tax. Understanding how it works helps you budget more accurately and recognize when you might be able to reduce what you pay.
Quick answer: what is sales tax?
Sales tax is a percentage added to the price of most goods and some services at the point of purchase. The tax is collected by the seller and sent to state and local governments to fund public services like schools, roads, and emergency services.
Unlike income tax, which is based on what you earn, sales tax is based on what you spend. It’s a consumption tax.
How sales tax works
When you make a taxable purchase, the merchant calculates the sales tax based on the local rate and adds it to your bill. The merchant then forwards the collected tax to the appropriate government agencies.
Sales tax has three potential components:
- State sales tax: Set by the state. Ranges from 0% to about 7%.
- County or city sales tax: Local jurisdictions often add their own tax on top of the state rate.
- Special district tax: Some areas have additional taxes for transit, tourism, or other local purposes.
Your total sales tax rate is the sum of all applicable layers. Two cities in the same state can have very different total rates.
Sales tax rates by state
Sales tax rates vary widely across the United States. A few examples (combined state + average local):
| State | Combined Average Rate (Illustrative) |
|---|---|
| Alaska | 1.8% |
| Delaware | 0% (no sales tax) |
| Florida | 7.0% |
| Hawaii | 4.5% |
| Illinois | 8.8% |
| Louisiana | 9.5% |
| Montana | 0% (no sales tax) |
| New Hampshire | 0% (no sales tax) |
| New York | 8.5% |
| Oregon | 0% (no sales tax) |
| Tennessee | 9.5% |
| Texas | 8.2% |
Rates change over time and by locality. Five states have no state sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon (though local taxes still apply in parts of Alaska).
What’s usually taxed — and what isn’t
Most physical goods are taxed: clothing, electronics, furniture, prepared food, alcohol, fuel. But many things are exempted or taxed at lower rates in specific states. Common exemptions:
- Groceries: Many states exempt unprepared food (raw meat, produce, dairy) from sales tax. Others tax it at a reduced rate.
- Prescription medicines: Almost universally exempt.
- Medical supplies and devices: Often exempt.
- Clothing: A handful of states (Pennsylvania, Minnesota, New Jersey) exempt most clothing entirely.
- Most services: Many states tax goods only, leaving services like haircuts, accounting, and legal services untaxed. But this is changing — more states have begun taxing services.
Each state has its own list. Two grocery stores in different states selling the same item may apply different tax.
Online and out-of-state purchases
For years, online purchases from out-of-state sellers escaped sales tax in many cases. That changed with the 2018 Supreme Court decision in South Dakota v. Wayfair, which allowed states to require online retailers to collect sales tax even without a physical presence in the state.
Today, most major online retailers collect sales tax based on the buyer’s shipping address. Small sellers under certain thresholds may not collect it — but you may still owe what’s called a use tax to your state. Use tax is a self-reported tax on items bought from sellers who didn’t collect sales tax. Most people don’t pay it because most online sellers now collect, and enforcement is rare for individuals.
Sales tax holidays
Many states designate one or more weekends per year as sales tax holidays — brief periods when certain items (often back-to-school clothing, school supplies, or hurricane preparedness items) are exempt from sales tax. Common examples:
- Back-to-school holiday: Clothing, shoes, computers, school supplies, usually in July or August.
- Emergency preparedness holiday: Generators, batteries, flashlights, before hurricane season in some Gulf and Atlantic states.
- Energy efficiency holiday: Energy Star appliances in some states.
Limits often apply (e.g., individual items under $100). Check your state’s revenue department website for current rules.
Sales tax vs. other taxes
| Tax | What It’s Based On | Who Collects It |
|---|---|---|
| Sales tax | Purchases of goods/services | Merchants → state and local |
| Income tax | Wages, salary, investment income | Employer (withholding) and IRS / state |
| Property tax | Value of real estate | County or municipality |
| Excise tax | Specific products (gas, alcohol, tobacco) | Built into the price |
| Use tax | Out-of-state purchases not taxed at sale | Self-reported to state |
How sales tax affects your budget
Sales tax is invisible until you do the math. For someone spending $30,000 a year on taxable goods at an 8% combined rate, that’s $2,400 a year in sales tax — about $200 per month.
This is why states without income tax (like Texas and Florida) often have higher sales tax and property tax to compensate. The total tax burden depends on the mix, not just the headline rates.
Practical ways to reduce sales tax
- Buy groceries at the store. Most unprepared food is exempt or taxed at a reduced rate. Prepared food (deli sandwiches, hot meals) is often taxed at the full rate.
- Time big purchases for sales tax holidays. Buying a laptop or back-to-school clothing during a tax holiday saves the full tax.
- Shop in a lower-tax jurisdiction if it’s convenient. A nearby town with a lower local rate can mean meaningful savings on larger purchases.
- Buy from sellers in states without sales tax when applicable, though most online retailers now collect tax based on your address regardless.
