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>
