California has the highest statewide sales tax rate at 7.25 percent

California's base sales tax rate is 7.25 percent, which is the highest in the country when you look at what the state itself charges. However, the total tax you pay at checkout is almost always higher because counties and cities add their own local sales taxes on top of the state rate. In California, combined rates typically range from 7.25 percent to over 10 percent depending on where you shop.

Several other states tie with California's 7.25 percent state rate: Tennessee, Louisiana, Arkansas, and Alabama all charge 7.25 percent at the state level. But again, the final amount you pay includes local additions, so the total varies by location within each state.

Key Takeaways

  • California, Tennessee, Louisiana, Arkansas, and Alabama all have a 7.25 percent state sales tax rate, which is the highest in the nation.
  • Your actual sales tax at checkout includes both state and local taxes, so the total rate depends on your city and county, not just your state.
  • Some states have no sales tax at all, while others charge rates as low as 2.9 percent at the state level.
  • Combined sales tax rates (state plus local) can exceed 10 percent in certain cities and counties across multiple states.

How state and local sales taxes combine

The statewide rate is only part of what you pay. When you buy something, the retailer collects the state tax plus any local tax that applies in that specific location. A city might add 1 percent, a county might add another 0.5 percent, and a special district might add 0.25 percent. These stack on top of the state rate.

This is why two people in the same state can pay different sales tax amounts. Someone buying groceries in one California city might pay 7.25 percent total, while someone in another city pays 8.5 percent or higher. The state rate stays the same, but the local portion changes.

States with the highest combined sales tax rates

When you add state and local taxes together, Tennessee and Louisiana often have the highest combined rates in the country. Tennessee's combined rate can reach 9.55 percent in some cities. Louisiana's combined rate can exceed 10 percent in certain parishes. These highs occur in specific locations where cities and parishes layer their own taxes on top of the state rate.

California, despite having the highest state rate, does not always have the highest combined rate because some California cities have lower local additions. The combined rate varies significantly depending on which city or county you are in.

States with no sales tax

Five states charge no sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows cities and boroughs to charge local sales taxes, so the total you pay still depends on location. The other four states have no state or local sales tax.

New Hampshire and Montana do not tax most purchases, though New Hampshire taxes prepared meals and lodging. Oregon does not tax clothing or groceries. These states make up for lost revenue through other taxes, such as income tax or property tax.

States with the lowest sales tax rates

Colorado, Georgia, Hawaii, Louisiana, New York, Wyoming, and several others charge 4 percent or less at the state level. Colorado and Georgia both charge 4 percent. Hawaii charges 4 percent on most items, though some goods and services are taxed differently. These lower rates still increase when local taxes are added.

The lowest state rate in the nation is 2.9 percent, which Colorado charges on certain transactions. However, Colorado's standard rate is 4 percent, and most purchases are taxed at that rate plus local additions.

Why sales tax rates vary so much

States set their own tax rates based on their budget needs and tax policy choices. Some states rely heavily on sales tax to fund schools, roads, and services. Others use income tax or property tax instead. Local governments also decide whether to add their own sales taxes to fund schools, public safety, or infrastructure.

Over time, states and cities adjust their rates based on revenue shortfalls or spending priorities. A city might raise its local sales tax to fund a new transit system or school renovation. A state might lower its rate to attract businesses. These decisions mean rates change periodically, so the highest-tax state today might not be the highest next year.

How to find the exact rate where you shop

Your state's Department of Revenue or Tax Commission publishes current sales tax rates by city and county. You can search online for "[your state] sales tax rate" and find an official lookup tool. Many states let you enter a zip code and see the combined rate for that location.

Retailers are required to charge the correct rate for the location where the sale happens. If you buy something in person, the tax is based on the store's location. If you order online, the tax depends on where the item is shipped. Some online retailers charge tax based on your shipping address, while others charge based on their warehouse location or business location, depending on state law.
