Which US states have no sales tax?

Five states have no state-level sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local municipalities to levy their own sales tax, so some areas in Alaska do charge sales tax at the local level.

How is sales tax calculated?

Sales tax is calculated by multiplying the purchase price by the applicable tax rate. For example, a $100 item in Texas (6.25% state rate) incurs $6.25 in tax, making the total $106.25. If local taxes apply, those are added on top.
