You can configure the system so that it extracts several tax-related values. The system converts these tax values to a valid amount using a period as a decimal separator.

By default, the following fields are used in most solutions.

• SubTotal.

  This field contains the sum of all net amounts.

• Tax Amount 1.

  This field usually contains the tax amounts charged on an invoice. If you are processing European invoices with multiple VAT rates this field contains the tax charged to Net Amount 1.

If you are processing European invoices, or invoices with VAT, then you can activate the following additional fields as required.

• Net Amount 0.

  This field contains the extracted amounts on the document that have a tax rate of zero.

• Net Amount 1.

  This field contains the subtotal of all amounts on the document that use Tax Rate 1. When an invoice has one tax rate, Net Amount 1 usually equals the SubTotal.

  Net Amount 1 may contain a calculated value if freights are charged. The SubTotal does not contain this freight amount.

  Also, if the amount that Net Amount 1 is charged against is not printed on the document, Net Amount 1 may contain a calculated value.

• Net Amount 2-4.

  These fields contain the extracted amounts on the document that have other tax rates.

• Tax Rate 1-4.

  These fields contain the tax rates for their corresponding net amounts.

  Tax Rate 1 may be set automatically based on a calculated value.

• Tax Amount 2-4.

  These fields contain additional tax amounts for their corresponding net amounts.

If you want to use any of the disabled VAT-related fields, activate them via the Settings > Invoice Processing > Capture Profiles > Field Settings.

Once these fields are active, you must also enable the Activate VAT Based Tax Processing setting in the Settings > Invoice Processing > Capture Profiles > Tax Settings > Tax Configuration tab.

Each group of fields is subject to a mathematical calculation. For example,

Tax Amount = Net Amount * (Tax Rate / 100)

In terms of the mathematical check applied to all amounts captured from the invoice, SubTotal is calculated from the sum of the taxable amounts. The overall invoice tax is calculated from the sum of the Tax Amounts.

The tolerance applied to all of these mathematical checks is based on the tolerance group assigned to the invoice currency. This is set in the Settings > Invoice Processing > Global Settings > Tolerance Settings.
