Frequently asked questions

Which US state has the highest sales tax?

California has the highest state-level sales tax rate at 7.25%. When combined with local district taxes, some California cities exceed 10.25%. Tennessee and Louisiana have high combined rates when local taxes are factored in, regularly reaching 9%–10% in major cities.

Which US states have no sales tax?

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska is the notable exception — while there is no state-level tax, local municipalities are allowed to impose their own sales taxes, so some Alaskan cities do charge sales tax.

How is sales tax calculated?

Sales tax is calculated by multiplying the purchase price by the applicable combined tax rate. For example, a $500 item purchased in a city with an 8.25% combined rate results in $41.25 of tax and a $541.25 total. The rate is the sum of the state rate plus any county and city additions.

What is the difference between state and combined sales tax rate?

The state rate is set by the state legislature and applies uniformly across the state. The combined rate includes the state rate plus any additional local taxes added by counties, cities, or special taxing districts. Most shoppers pay the combined rate, which can be significantly higher than the state rate alone.

Is sales tax charged on services?

It depends on the state. Most states primarily tax the sale of physical goods and exempt services. However, some states like New Mexico, Hawaii, and South Dakota apply broad taxes that include many services. Digital goods and software-as-a-service are also taxed inconsistently across states.

What is the difference between sales tax and use tax?

Sales tax is collected by the retailer at the point of sale and remitted to the state. Use tax is owed by the buyer when they purchase an item from an out-of-state seller who did not collect sales tax — for example, an online purchase shipped from another state. Use tax rates are identical to the sales tax rate in the buyer's state and are technically owed even if rarely enforced on individuals.

Do you pay sales tax on groceries?

It depends on the state. Most states exempt unprepared groceries from sales tax — including California, Texas, Florida, Ohio, and Pennsylvania. However, states like Tennessee, Alabama, and Mississippi tax groceries at either the full rate or a reduced rate. Prepared food (restaurant meals, ready-to-eat items) is taxable in almost every state.
