How can I fix the error "ATS-291: Object referenced not set to an instance of an object"?

Overview

You are intermittently getting the error "[ATS-291]: Object referenced not set to an instance of an object when trying to calculate tax on an invoice."

Environment

QuickBooks

Resolution

  • This issue was resolved with v77.00 of AvaTax for QuickBooks.
  • If you are on an older version of Quickbooks, please update to the latest version of AvaTax for QuickBooks on all workstations and the server (if applicable).
  • As a work around, you can also disable the option "Send Item Account to Avalara".
    • This is found on the "General" tab in the AvaTax configuration.
