Purchase Orders calculates a tax amount on purchase orders, receipts, invoices, returns, credit notes, and debit notes if all three of the following conditions apply:
- You have entered tax rates for the applicable tax authorities and classes in Tax Services.
- The vendor for the document is subject to tax.
- The transaction contains taxable items or taxable additional costs.
In Purchase Orders, tax information is calculated and displayed for individual details and for the total purchase order, receipt, invoice, return, credit note, or debit note. (No tax information is displayed for requisitions.)
Tax calculations are based on the rates entered for the various authorities and tax classes in Tax Services.
You can edit some tax information for individual detail lines, but you can change tax amounts directly only for the document as a whole. To change tax amounts for the primary vendor, use the Taxes tab on the transaction-entry screen. For secondary vendors, use the Additional Cost Vendor Taxes screen.
