Tax Codes cannot be read from the accounting system and need to be entered in XML format in the Accounting Settings Screen. 


The format should be as follows.


<ArrayOfSupplierTaxCode>
    <SupplierTaxCode>
        <TaxCode>GST</TaxCode>
        <Name>GST</Name>
        <Percent>10</Percent>
    </SupplierTaxCode>
    <SupplierTaxCode>
        <TaxCode>FRE</TaxCode>
        <Name>GST Free</Name>
        <Percent>0</Percent>
    </SupplierTaxCode>
</ArrayOfSupplierTaxCode>
