Overview

Receiving the following error when attempting to save a transaction:   Tax could not be calculated: Arithmetic operation resulted in an overflow.

Environment

QuickBooks

Resolution

  • The document is not being closed by QuickBooks before Avalara AvaTax attempts to write to the document to add tax
  • This is most often the result of using the Save button at the top of the invoice
    • Use the Save and Close or Save and New options at the bottom of the invoice
  • In the AvaTax Configuration (File > Avalara) under Tax Calculation check Ignore multiple events during 'SendForms'
  • QuickBooks may be hung up processing the save, restarting QuickBooks (or the computer) may be necessary.
