To uninstall the AvaTax for QuickBooks connector from QuickBooks, perform the following steps.

  • For QuickBooks 2011 & 2012, while logged into QuickBooks, navigate to Edit > Preferences and ensure that "Keep QuickBooks running for quick start-up" is UNCHECKED.  For QuickBooks 2010 and older, ignore this step. 
  • Close out & exit QuickBooks.  Enter the Windows Task Manager, click on the Processes tab, and ensure that QBW32.EXE is not running.  If it is, end the process.
  • Navigate to the workstations Add / Remove programs feature, found within the Windows Control Panel. 
  • Locate the AvaTax for QuickBooks item and uninstall completely.
  • (OPTIONAL) Once the Uninstall is complete, navigate to C:\Program Files\ (or C:\Program Files (x86) for 64-bit Windows) and delete the Avalara folder. NOTE:  Doing this will completely remove all the Avatax for Quickbooks credentials and settings from the computer.

AvaTax for QuickBooks is now uninstalled.
