Sales Tax by State in 2026

Sales tax can change what everyday life actually costs in 2026, especially when local rates push totals higher than the statewide number. If you are comparing states, cities, or relocation costs, it helps to look at combined sales tax, not just the base rate.

This guide breaks down 2026 sales tax by state so you can quickly compare rates and make better budgeting decisions.

How Sales Tax Works

When you buy a product or service, the sales tax is calculated as a percentage of the purchase price. This percentage, known as the sales tax rate, varies significantly depending on where the transaction takes place. Most states have a statewide sales tax rate, and many also allow local jurisdictions like cities and counties to levy their own additional sales taxes. This results in a combined sales tax rate that can differ even between neighboring towns.

The Sales Tax Formula

The formula to calculate sales tax is straightforward:

Sales Tax = Purchase Price × Sales Tax Rate

To find the total cost of an item including sales tax, you would use the following formula:

Total Cost = Purchase Price × (1 + Sales Tax Rate)

For example, if you purchase an item for $100 in a location with a combined sales tax rate of 8%, the calculation would be:

• Sales Tax = $100 × 0.08 = $8
• Total Cost = $100 + $8 = $108

Worked Examples

Let's look at a few examples to see how sales tax is calculated in different states:

• California: With the highest state sales tax rate at 7.25%, a $500 purchase would incur a state sales tax of $36.25. However, with an average local tax of 1.74%, the combined rate is 8.99%. So, the total tax would be $500 * 0.0899 = $44.95.
• Colorado: Colorado has the lowest non-zero state sales tax rate at 2.9%. A $200 purchase would have a state sales tax of $5.80. But with a high average local tax rate of 4.99%, the combined rate is 7.89%. The total tax would be $200 * 0.0789 = $15.78.
• Florida: In Florida, a $1,000 purchase with a 6% state sales tax would have $60 in state tax. With an average local tax of 0.98%, the combined rate is 6.98%, making the total tax $69.80.

States With No Sales Tax

There are five states that do not have a statewide sales tax:

1. Alaska
2. Delaware
3. Montana
4. New Hampshire
5. Oregon

While these states don't have a statewide sales tax, Alaska and Montana allow localities to charge local sales taxes.

Understanding Combined Sales Tax Rates

It's crucial to consider the combined state and local sales tax rate to understand the true cost of a purchase. A state with a low statewide sales tax rate might have high local sales taxes, resulting in a higher overall tax burden than a state with a higher statewide rate but low or no local taxes.

For example, Louisiana has a state sales tax of 5.00%, which is lower than many other states. However, it has the highest average local sales tax rate in the nation at 5.11%, leading to the highest combined sales tax rate of 10.11%.

Frequently Asked Questions (FAQs)

Which states have no sales tax?

As of 2026, Alaska, Delaware, Montana, New Hampshire, and Oregon do not have a statewide sales tax.

How do you calculate sales tax backwards?

To calculate the original price of an item before sales tax was added, you can use the following formula:

Original Price = Total Cost / (1 + Sales Tax Rate)

For example, if the total cost of an item was $108 and the sales tax rate was 8%, the original price would be $108 / 1.08 = $100.

Is sales tax included in the price?

In the United States, the sales tax is almost always calculated and added to the price at the time of purchase. The price you see on the shelf or tag is the pre-tax price.

What is use tax?

Use tax is a tax on the storage, use, or consumption of a taxable good or service on which no sales tax has been paid. It is typically incurred when you buy something from an out-of-state or online seller who does not collect sales tax from you. The use tax rate is the same as the sales tax rate in your location.

Are groceries subject to sales tax?

This varies by state. Most states exempt groceries from sales tax, while some tax them at a lower rate, and a few tax them at the full state rate.
