Why is QuickBooks Online showing twice the tax amount?


QuickBooks Online is showing tax calculated by AvaTax and by QBO.


QuickBooks Online


  • When the AvaTax app is activated, QBO will start to use AvaTax to calculate tax.
  • You will need to make sure that any previous tax item has been removed or is not use on transactions.
    • If a QBO Native tax item is used, the amount of tax will add to what AvaTax has calculated, doubling the tax and displaying two tax calculation lines on your printed invoice
  • To fix, remove the native tax item from the transaction (see screenshot), add the AvaTax tax item and save.
