You would like transactions to automatically push to the error list without running the Reconcile Tax tool.
Check the AvaTax settings in Quickbooks
File > AvaTax > Configuration > Tax Calculation
On the "Tax Calculation" tab check "Disable Automatic Calculation (Memorized transaction)".
Uncheck all options (Quotes, Sales Order, Receipt, Invoice and Credit Memo) under "Disable Automatic Calculation on Sales Doc".
