California has the highest state sales tax rate at 7.25 percent

California's base state sales tax is 7.25 percent, the highest in the country. However, the total tax you pay at checkout is usually higher because counties and cities add their own local sales taxes on top of the state rate. In some California cities, the combined rate reaches 10.5 percent or more.

Tennessee, Louisiana, and Arkansas also have state rates of 7 percent or higher. But when you add local taxes, the actual rate you pay varies significantly by location. A purchase in one city might be taxed at 8.5 percent while the same purchase across the county line costs 9.2 percent.

The highest combined sales tax rates in the country — sometimes reaching 10.5 percent or above — occur in specific cities and counties, not entire states. These hotspots exist in California, Louisiana, and a few other states where local jurisdictions layer their own taxes on top of already-high state rates.

Key Takeaways

  • California's state sales tax of 7.25 percent is the highest in the nation, though most purchases there are taxed higher due to local add-ons.
  • Tennessee, Louisiana, and Arkansas have state rates of 7 percent or higher, making them among the highest-tax states.
  • The total tax you pay depends on your city and county, not just your state, because local governments add their own rates on top.
  • Some cities in California and Louisiana have combined rates above 10 percent when state and local taxes are added together.

How state and local sales taxes stack together

Sales tax is not a single number. Your state sets a base rate, then your county adds a rate, then your city may add another. All three stack on top of each other. A state with a 7 percent rate might have a city that adds 2 percent, bringing your total to 9 percent at the register.

This is why two people in the same state can pay different sales tax rates. Someone buying groceries in Los Angeles pays a different rate than someone in San Francisco, even though both live in California. The state rate is the same, but the local rates differ.

When people ask which state has the highest sales tax, they usually mean the state rate alone. But when you actually shop, you pay the combined rate. Understanding both numbers helps you know what to expect when you check out.

States with the highest base sales tax rates

Four states tie or nearly tie for the highest state-level sales tax: California (7.25 percent), Tennessee (7 percent), Louisiana (7 percent), and Arkansas (7 percent). A few other states have rates of 6.85 percent or 6.875 percent, but these four lead.

These high state rates mean residents in these states start with a higher baseline tax before any local taxes are added. If you live in a city that also charges local sales tax, your total rate will be noticeably higher than in states with lower base rates.

States with no sales tax — Alaska, Delaware, Montana, New Hampshire, and Oregon — have zero state rate. Some of these states allow cities to charge local sales tax, while others prohibit it entirely. This is why residents of these states often pay significantly less in sales tax overall.

Where combined sales tax rates reach their highest

The highest combined rates in the country occur in specific cities, not entire states. Long Beach, California has a combined rate of 10.25 percent. Certain areas of Louisiana, including parts of New Orleans, reach 10.45 percent or higher. These are the places where you will see the largest percentage added to your purchase.

These high combined rates happen because the state rate is already high, and then the local rate is also high. A state with a 5 percent rate and a city with a 2.5 percent local rate reaches 7.5 percent total. But a state with 7.25 percent and a city with 3 percent reaches 10.25 percent.

If you are moving to a new state or city, checking the combined sales tax rate for your specific location is more useful than knowing just the state rate. The combined rate is what you will actually pay.

Why sales tax rates vary so much by location

States set their own tax policy independently. Some states decided to fund government through sales tax rather than income tax. Others use both. This is why neighboring states can have very different rates.

Within states, cities and counties also make their own choices about local sales tax. A county might add 1 percent to fund schools. A city might add another 0.5 percent for transit. These local decisions stack on top of the state decision, creating the wide variation you see at checkout.

Some states allow local governments to set their own rates freely. Others cap how high local rates can go. A few states do not allow local sales tax at all. These policy choices explain why the same item costs different amounts in sales tax depending on where you buy it.

How to find the sales tax rate for your location

Your state's department of revenue or taxation website lists the state rate and usually shows local rates by county and city. You can search by your zip code or city name to find the exact combined rate that applies to your purchases.

Many retail websites and tax calculators also let you enter your location and see the rate that will apply. If you are shopping online, the rate charged depends on where the item is being shipped, not where you live or where the seller is located.

If you are moving or planning a large purchase in a different city, taking five minutes to look up the local rate can help you budget accurately. The difference between a 7 percent rate and a 10 percent rate adds up quickly on big-ticket items.

Frequently Asked Questions

Does California really have the highest sales tax in America?

California has the highest state sales tax rate at 7.25 percent. However, some cities in Louisiana and other states have higher combined rates when local taxes are included. So California has the highest state rate, but not necessarily the highest total rate you will pay at checkout.

What is the sales tax in Tennessee?

Tennessee's state sales tax is 7 percent, tied for second-highest in the nation. Most cities and counties in Tennessee add local sales tax on top of this, bringing the combined rate to 8 or 9 percent in many areas. Check your specific city for the exact rate.

Can I avoid sales tax by shopping in a different state?

No. Sales tax is based on where you buy the item or where it is shipped to, not where you live. If you buy something online and have it shipped to California, you pay California's rate. If you buy it in person in a low-tax state but live in a high-tax state, you pay the rate of the state where you made the purchase.

Do any states have zero sales tax?

Yes. Alaska, Delaware, Montana, New Hampshire, and Oregon have no state sales tax. Some of these states allow cities to charge local sales tax, while others prohibit it. If you live in one of these states, you pay significantly less in sales tax overall.
