Error: We're sorry, QuickBooks encountered an error while calculating tax

How to determine the cause and solution for QuickBooks error message "We're sorry, QuickBooks encountered an error while calculating tax."


When syncing a transaction to QuickBooks, the following error message from QuickBooks is returned to Connex:

Error: We're sorry, QuickBooks encountered an error while calculating tax. Try re-selecting the tax rate or reentering the product/service item and saving the form again.


QuickBooks does not allow the mapped tax code on a specific transaction. In general, this could mean that QuickBooks has deactivated (made inactive) some of the sales tax codes and a new one must be mapped. Alternatively, this can be caused by renaming sales tax codes. This most commonly occurs on international versions of QuickBooks.
