How this calculator works
- Sales tax = price × combined rate. The combined rate is your state base rate plus any county, city, and special-district rates at the point of sale.
- Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon (localities in Alaska may still charge).
Frequently asked questions
Which state has the highest sales tax?
By combined average, Louisiana and Tennessee top the list at around 9.5–10%; individual cities elsewhere (e.g. in Washington or Alabama) can exceed 10%.
Do online purchases get taxed?
Yes — since the Wayfair decision (2018), major online retailers collect sales tax based on your delivery address in nearly all taxing states.
Are groceries taxed?
Most states exempt or reduce tax on unprepared groceries, but rules differ — some tax them fully, and prepared food is almost always taxable.
