Overview

You are trying to calculate tax on an invoice but keep getting the error "Tax could not be calculated: Input string was not in a correct format." and cannot calculate tax when you save.

Environment

QuickBooks

Resolution

  • Change the quantity to a number with 4 or fewer digits after the decimal point (ex: 0.1234)
    OR
  • Make sure the quantity is a whole number

 

Note: QuickBooks allows up to 5 digits after the decimal point (ex: 0.12345) but this number exceeds the allowable digits after the decimal point for this field in the Avalara service
