Why is my invoice calculating wrong tax rate?


You see that the typical rate for a jurisdiction is higher than the rate showing on your invoice and want to know why.

  • Please check the address to confirm it is in the expected location and valid.
    • If an address is invalid, it could calculate unexpected rates.
  • Please check if any exemptions or entity use codes are applied.
    • There are certain exemption types that change tax rates for some jurisdictions.
  • Please check the tax date of the transaction.
    • If you have selected to override the tax date, then the rates may changed based off of what they were at that time.
