Why am I receiving an error in QuickBooks Online when trying to estimate tax?


When I try to estimate tax on a specific invoice I receive errors stating:

Error occurred in Tax calculation. Please try again. When I view the error it is a blank message.

  • This can happen if your invoice includes lines that have no Product/Service or no Amount.
  • You'll need to make sure that each line has a Product/Service selected before you hit Estimate tax.
