Which states have no sales tax?

Alaska, Delaware, Montana, New Hampshire, and Oregon have no state-level sales tax. However, some localities in Alaska do impose local sales taxes.

It varies by state. Most states exempt unprepared food and groceries from sales tax, but some states like Alabama, Mississippi, and South Dakota tax groceries at the full rate.

Use tax applies to purchases made out-of-state or online where sales tax wasn't collected. It's typically the same rate as your local sales tax and is legally owed by the buyer.

How do combined state and local rates work?

Your total sales tax rate is the sum of the state rate plus any county, city, and special district rates. For example, New York City's 8.875% combines the 4% state rate with 4.5% city rate and 0.375% metro commuter district surcharge.

How Sales Tax Works

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and certain services. The tax is calculated as a percentage of the purchase price and collected by the retailer at the point of sale.

The Formula

Tax Amount = Price × (Tax Rate ÷ 100)
Total Price = Price + Tax Amount
