Why does a zip code listed with the wrong state have tax applied for that state?


You calculated tax using only a zip code and state as the address, and you see tax is being applied for the state listed, but you have determined that the customer is actually in a different state. You want to know how to avoid this issue.

  • When an address is not valid because the street address and city are incorrect or missing, you can receive tax based on the state listed
  • We recommend using a full correct address to receive the most precise tax calculation


Note​: We require a minimum of a zip code and state to calculate tax in the US if a full valid street address, city and state are not provided, it is your responsibility to ensure the state and zip code provided are accurate when using only zip code and state.
