Add Tax Exemption Details to an Invoice

When adding a tax exempt line or creating a reverse change invoice, add this element to your cXML:

<Description xml:lang="en-US">Line level exemption reason</Description>

Include the <Description> element immediately after <tax-amount>, as shown in line 16 in the example below. It's required when the TaxDetails category contains an exemption.

<InvoiceDetailServiceItem invoiceLineNumber="3" quantity="">
  <InvoiceDetailServiceItemReference lineNumber="3" />
  <SubtotalAmount>
    <Money currency="ZAR">14000</Money>
  </SubtotalAmount>
  <Tax>
    <Money currency="ZAR">0</Money>
    <Description xml:lang="en-GB">VAT</Description>
    <TaxDetail category="VAT Exempt" percentageRate="0" purpose="tax">
      <TaxableAmount>
        <Money currency="ZAR">0</Money>
      </TaxableAmount>
      <TaxAmount>
        <Money currency="ZAR">0</Money>
      </TaxAmount>
      <Description xml:lang="en-US">Line level exemption reason</Description>
    </TaxDetail>
  </Tax>
</InvoiceDetailServiceItem>
