Why is my invoice tax amount off by a few cents?


An invoice doesn't show the exact tax amount expected, based off the flat tax rate - it's off by a few cents.




  • Small differences like this are generally due to Rounding.
    • Rounding produces different results depending on how you Control Rounding in Settings > All AvaTax settings > Advanced Company Settings > Manage.
  • To understand the differences in AvaTax's two types of rounding, please see Change how AvaTax Update rounds the tax amount

Note: If you use more than one accounting system with AvaTax, please make sure the invoice and/or order match between the two systems and both systems use the same rounding level.
