How do I resolve "It is required to set Registration Number to Exempted Tax Class for making transaction exempted, cannot proceed with AvaTax." in Sage 300

Overview

I am receiving the error "It is required to set Registration Number to Exempted Tax Class for making transaction exempted, cannot proceed with AvaTax." in Sage 300.

Environment

Sage 300

Resolution

  • This occurs because the "Registration Number" field on the customer record is empty and the "Tax Class" is set to '2'.
  • This field can be found on the customer record, in the Invoicing tab in the lower section of the window. Once data is in the field the error will not appear and communication with AvaTax will resume for this customer.
