About Changing the Tax Class for a Single Invoice Distribution
If you do not select Enter as the tax entry method for an invoice, debit note, or credit note, you can change the tax allocation for a distribution line only by changing the tax class or the Tax Included status for the distribution line before you calculate and distribute taxes for the document.
Enter the invoice, debit note,or credit note, as usual.
To change the detail tax class or tax-included setting for a distribution line:
Change the Tax Class or the Tax Included setting.
Important! You can change the Tax Included setting only if the tax authority permits.
Note: If you changed the detail tax class to a non-taxable class, when you calculate tax, the total tax amount is reduced and is prorated over all other distribution lines based on their percentages of the total amount.
On the Taxes tab of the A/P Invoice Entry screen, click Calculate Taxes or Distribute Taxes.
