  • Check the transaction, it must have an item code and an item description
  • Check that the tax code is SST approved, this is listed in the AvaTax Pro Toolkit
    • The tax code NT is not acceptable for SST use
    • Choose a tax code that matches the description of the product or service provided.


Note: To adjust these transactions add an item and description, or utilize a tax code that is SST approved.
