Frequently asked questions
How is sales tax calculated?
Multiply the pre-tax price by the rate: a $40 item at 8.25% adds $3.30 of tax for a $43.30 total. Rates combine state, county, and city portions, which is why neighboring towns can differ.
How do I remove sales tax from a total?
Divide the total by one plus the rate. A $43.30 receipt at 8.25% is 43.30 / 1.0825 = $40.00 pre-tax. Subtracting the percentage instead is a common mistake that gives the wrong answer.
What are typical US rates?
Combined state and local rates run from 0% (Oregon, Montana, New Hampshire, Delaware) to about 9.5%+ in parts of Louisiana, Tennessee, and Washington state. 6% to 9% covers most of the country.
