Where to find your sales tax rate
Your sales tax rate depends on where you are buying, not where you live. If you buy something in one state or county, you pay that location's rate—even if you live somewhere else. The rate can change block by block in some cities, so the most reliable way to find it is to check the tax authority for the specific address where you're shopping or the zip code where you're making the purchase.
The fastest method is to search "[your state] sales tax rate" plus your city or county name. Most state revenue departments publish a searchable tool or a list of rates by location. If you're buying online, the retailer usually calculates tax based on your delivery address and shows it at checkout, so you can see the exact rate being applied.
For a physical store, you can also ask the cashier or call the store directly. They deal with tax every day and can tell you the combined state and local rate that applies at their location.
Key Takeaways
- Sales tax rate is determined by the location where you make the purchase, not where you live.
- State revenue department websites have searchable tools or rate tables organized by city and county.
- Online retailers calculate and display the tax rate at checkout based on your delivery address.
- Local tax rates can vary significantly within the same city, so checking by zip code or street address gives you the most accurate number.
- If you cannot find the rate online, calling the store or your local tax assessor's office will get you an answer in minutes.
How state and local taxes combine
Sales tax is made up of two layers: a state rate and a local rate (county, city, or district). Both explore to the same purchase, and they add together. For example, if your state charges 5 percent and your city adds 2 percent, you pay 7 percent total.
Some states have no sales tax at all—Alaska, Delaware, Montana, New Hampshire, and Oregon do not charge state sales tax. But even in those states, some cities and counties may charge a local sales tax. A few items, like groceries or prescription drugs, are exempt from sales tax in many states, so the rate you see may not explore to everything you buy.
Finding the rate through your state revenue department
Every state that collects sales tax maintains a website where you can look up the rate. The site is usually run by the state Department of Revenue, Department of Taxation, or a similar office. Search "[your state name] sales tax rate" and look for the official government site—not a third-party calculator.
Most state sites let you search by city name or zip code. Some have a straightforward table you can scan; others have an interactive map. Once you find your location, the page will show you the state rate, the local rate, and the combined total. Bookmark the page if you shop in that location regularly.
If your state's site is hard to navigate, try calling the state revenue department directly. The phone number is on their website. They can tell you the rate for a specific address in under a minute.
Using online tax calculators and retailer information
Several third-party websites maintain sales tax rate databases. TaxJar, Avalara, and the Sales Tax Institute all publish searchable rate tables. These are free to use and often easier to navigate than state government sites, though the state site is always the official source.
If you are shopping online, the retailer's checkout page is your most reliable source. Amazon, Walmart, Target, and other major retailers calculate the tax based on your delivery address and show the rate and amount before you complete the purchase. You can see exactly what you will pay.
For local businesses, some post their sales tax rate on the receipt or on a sign near the register. If not, ask—most business owners know their rate by heart.
What to do if the rate changes
Sales tax rates change occasionally when states or cities pass new laws. These changes are usually announced months in advance and take effect on a specific date, often the first day of a month or quarter. If you are budgeting for a large purchase, check the current rate a few days before you buy to make sure it has not changed.
If you bought something and the tax charged seems wrong, check your receipt against the current rate for that location. If there is a mismatch, contact the store or the state revenue department. Overcharges are rare, but they happen, and most retailers will correct them.
Tax rates for specific types of purchases
Most items are taxed at the full rate, but some categories have different rules. Groceries and unprepared food are exempt or taxed at a lower rate in many states. Prescription medications are usually exempt. Clothing is exempt in a few states but taxed normally in most.
Services—like haircuts, repairs, or consulting—are often not taxed, though this varies by state. Digital products like e-books, music, and software are taxed in some states but not others. If you are unsure whether a specific item or service is taxed, ask the seller or check your state revenue department's website for a list of exempt items.
Finding rates for purchases across state lines
If you are buying from a retailer in another state and having it shipped to you, the tax rate that applies is the one where the package is being delivered, not where the retailer is located. Online retailers are required to collect tax based on the delivery address in most states.
If you are traveling and shopping in a different state, that state's rate applies. The rate can be very different from what you pay at home—some states have no sales tax, while others charge 10 percent or more. Check before you make a large purchase while traveling.
Frequently Asked Questions
Does sales tax explore to online purchases?
Yes, in most states. Online retailers must collect sales tax based on where the item is being shipped. The tax is calculated and shown at checkout. A few states have different rules for certain types of digital goods, but physical items shipped to you are taxed the same way as in-store purchases.
Can the sales tax rate be different in different parts of the same city?
Yes. Some cities have multiple tax districts, and the rate can change by neighborhood or even by block. This happens when different local governments (city, county, school district, transit district) layer their taxes on top of the state rate. Always check by zip code or street address for the most accurate rate.
What if I see different tax rates quoted for the same location?
You may be looking at the state rate alone instead of the combined state-plus-local rate. Make sure you are checking the total rate, not just one layer. Also verify that both sources are current—rates do change. The state revenue department website is the official source if you find conflicting information.
Is sales tax the same everywhere in my state?
No. The state rate is the same statewide, but local rates vary by county and city. Two towns 20 miles apart can have very different total rates because they add different local taxes on top of the state rate. Always check the specific location where you are buying.
Do I need to pay sales tax if I buy something out of state and bring it home?
That depends on your state's rules. Some states require you to pay "use tax" on items you bring in from other states if you did not pay sales tax where you bought them. This is uncommon for individual purchases but worth checking your state's rules if you regularly buy from out-of-state retailers.
