How do I troubleshoot some of the common errors in AvaTax for QuickBooks (Desktop)?


A quick list of basic steps to follow when troubleshooting a multitude of AvaTax for QuickBooks errors.




  • Select Edit > Preferences and ensure that "Keep QuickBooks running for quick start-ups" is unchecked.  
  • Completely exit out of QuickBooks. 
    • Once QuickBooks is closed, Start the Windows Task Manager by pressing CTRL+SHIFT+ESC,  or launching from the taskbar menu (right-click the windows task bar and select "Start Task Manager").
      • In the Processes tab ensure that each of the following processes are not running (within the Windows Task Manager):
        • EventCallbackWrapper
        • AvalaraEventCallbackWrapper
        • QBW32,  any other files beginning with "QB", and any Intuit programs
  • Right click on the icon for QuickBooks, select "Run As Administrator". 
    • Log in as Administrator (if possible). 
    • If QuickBooks prompts you to manually navigate to the location of the Company File, do so. 
    • Attempt to enter File > AvaTax > Configuration. 
      • If it works, exit out, run QuickBooks normally.
  • If the previous step does not work, exit the program, and run QuickBooks normally, logging in as Admin once again.
  • Check for multiple versions of AvaTax in the Integrated Applications found in the preferences menu.
  • If these steps do not solve the issue, please contact Technical Support at or 877-780-4848

Note:  Although not necessarily required, for best outcomes, it is recommended that you are logged in as administrator and in single user mode.
