How sales tax is calculated

You might think calculating sales tax is simple - just take the price of a taxable product or service and multiply it by the sales tax rate. If only it were that simple. Consider the following questions: What is the correct tax rate? Who pays the sales tax? Is the product or service even taxable? It turns out the manner in which sales tax is calculated goes way beyond the numbers.

Why our sales tax calculator doesn't ask for a ZIP code

The purpose of zip codes is to help the US Postal Service with the delivery of mail. ZIP code boundaries can change, can be subsets of other zip codes, and often overlap. This makes them the wrong tool to use for determining sales tax rates in the United States.

Basing sales tax rates on a ZIP code risks applying not only an incorrect sales tax rate but remitting it to the incorrect jurisdiction. This can increase your company’s risk of audit and associated penalties, fines, and fees.
