Example Calculation
What would you pay in sales tax on a $500 purchase in Idaho?
On a $500 purchase in Idaho, the calculator multiplies by the combined state + average local sales tax rate. Idaho's state rate is 6%, and local add-ons can push the combined rate to roughly 7.20%, sales tax would be about $36 for a total of $536.
Result: The difference between the highest and lowest taxable states matters most for big purchases. On a $30,000 car, sales tax alone can range from $0 in no-sales-tax states to well over $2,500 in the highest-rate states. Five states have no state sales tax: Oregon, Montana, Delaware, New Hampshire, and Alaska (though Alaska allows local taxes).
