Why is QuickBooks not calculating tax after installing Avatax?

Overview

I just installed Avatax for QuickBooks and it isn't calculating tax.

Environment

QuickBooks

Resolution

This will happen if the last step of installing Avatax for QuickBooks is skipped:

 

  • Log out of QuickBooks
  • Right click QuickBooks and Run as Administrator
  • Log into QuickBooks in single user mode
  • Click File>Avalara>Configuration>Connections>Test Connection
  • Once you see a success close that window
  • You should now be calculating tax without issue after saving an invoice, there will be an Avatax window that pops up showing the calculation and call out to Avatax.
