Why is tax not calculating in QuickBooks suddenly?


AvaTax is not calculating tax in QuickBooks, when it had previously.




  • If you would like AvaTax to calculate tax on a save event, be sure that Disable Dialogue window is unchecked in the Tax Calculation tab of the Avatax Configuration.
    • To navigate there click:
    • File > Avatax > Configuration > Tax Calculation
  • Also make sure that each customer and transaction is linked to Avatax and set to taxable
    • Since AvaTax is a tax schedule, the customer and invoice must be marked as taxable to have a tax calculation

Note: If any AvaTax windows are open when trying to save a transaction, calculation will not take place. Please close any window that has the orange "A" icon.
