Sales tax calculator
To calculate sales tax, multiply the purchase price by the combined sales tax rate where the item is delivered (your state rate plus any local rate), then add it to the price. For example, a $100 purchase at a 7% combined rate carries $7.00 in sales tax, for a $107.00 total. The calculator below does this for any US state; because the local portion depends on your exact address, it defaults to your state's average local rate and links each state's official rate lookup for the precise figure.

How do you calculate sales tax?
Sales tax is a percentage of the sale price, collected by the seller and passed to the state (and, in most states, the local government where the buyer takes delivery). The formula is simple:
Sales tax = purchase price × combined rate. The combined rate is your state's base rate plus any county, city, or district rate that applies at the delivery address. Add the tax to the price for the total the customer pays.
Two things trip people up. First, the rate follows the destination in most states: an online order is taxed at the buyer's address, not the seller's. Second, the local portion can stack several districts (county plus city plus a transit district), which is why two addresses in the same state can carry different rates, and why the exact figure comes from an address lookup, not a single statewide number.

Which states have no sales tax?
Five states charge no statewide sales tax, remembered by the acronym NOMAD: New Hampshire, Oregon, Montana, Alaska, and Delaware. Four of them have no local sales tax either, so most purchases are tax-free. Alaska is the exception: it has no state sales tax, but its cities and boroughs can levy their own local sales tax, so you still pay tax in many Alaskan towns. Use the calculator's local-rate field to enter your Alaska municipality's rate.
Why does my local rate differ from the average?
The combined rate in the table is a statewide average. Your actual rate depends on the exact delivery address, because counties, cities, and special districts each set their own add-on. A big city often runs above its state average, while an unincorporated area may sit at the state base rate alone. The calculator lets you type your own local rate; to find it, use the official state lookup linked next to the calculator, which returns the precise combined rate for any address or ZIP.
