Why use Sales Tax Calculator?

Sales tax in the United States is a patchwork of state, county, city, and special-district rates. This calculator gives you a practical combined rate for Texas, Florida, California, and New York—either a state average or a named city when you need more precision. Forward mode answers: "What do I pay on a $249 item?" Reverse mode answers: "How much of this $108 total is tax?" Both use the same combined rate and round to cents. Check the disclaimer on each page and confirm rates with your state comptroller before relying on them for compliance.
