Why can't I just use the ZIP code?

There are often multiple tax rates per ZIP code, county, and city. Therefore, more accurate rates are determined based on street address.

Your sales tax rate

What do these rates mean?

  • The combined tax rate is the total sales tax of the jurisdiction for the address you submitted.
  • The jurisdiction breakdown shows the different tax rates that make up the combined rate.
  • While most taxable products are subject to the combined tax rate, some items are taxed differently at the state and local levels, so be sure to apply the correct taxes to your sale.

These are the current rates for the date and time you submitted the address, but may change at any time with new tax legislation.

The real trick is figuring out what needs to be taxed and then calculating the correct tax rate — which, depending on how your business operates, could mean learning the rules in any number of the more than 12,000 tax jurisdictions across the United States.

ZIP codes were created to help the U.S. Postal Service with the delivery of mail and are independent of any state revenue systems. The boundaries can change and often don’t line up with tax rate jurisdictions. This makes them the wrong tool to use for determining sales tax rates in the United States.

By basing sales tax on ZIP codes, you risk applying the wrong rates and remitting tax to the incorrect jurisdiction. Both of these errors increase your company’s risk of audit penalties, fines, and fees.
