Quickbooks IPP v3 Invalid Line TaxCode in the request

Question

Using the IPP v3 I am trying to submit an invoice with multiple lines with different taxcode(s), I am getting the following error when submitting an invoice with 2 lines with TaxCodeRef mapping to existing TaxCode(s).

<IntuitResponse xmlns="http://schema.intuit.com/finance/v3" time="2015-06-11T00:32:48.687-07:00">
  <Fault type="ValidationFault">
    <Error code="6100" element="Line.SalesItemLineDetail.TaxCodeRef">
      <Message>Invalid Line TaxCode in the request</Message>
      <Detail>Valid line TaxCodes for US should be TAX or NON. Supplied value: 8</Detail>
    </Error>
    <Error code="6100" element="Line.SalesItemLineDetail.TaxCodeRef">
      <Message>Invalid Line TaxCode in the request</Message>
      <Detail>Valid line TaxCodes for US should be TAX or NON. Supplied value: 9</Detail>
    </Error>
  </Fault>
</IntuitResponse>

Here is the submitted XML, TaxCode with Id 8 and 9 are defined and active.

Is it possible to submit one invoice with multiple lines having different TaxCodes for Quickbooks online ?

Answer 1

I think you're asking the wrong question. You're asking:

Is it possible to submit one invoice with multiple lines having different TaxCodes for Quickbooks online ?

But the error is telling you:

Valid line TaxCodes for US should be TAX or NON. Supplied value: 9

So the problem isn't that you're submitting different tax codes. The problem is that you're submitting an invalid tax code.

You submitted:

<ns0:TaxCodeRef>9</ns0:TaxCodeRef>

When the only valid submissions are:

TAX or NON

e.g.

<ns0:TaxCodeRef>TAX</ns0:TaxCodeRef>

or

<ns0:TaxCodeRef>NON</ns0:TaxCodeRef>

There are no other valid values for QuickBooks Online in the USA. Only TAX and NON.

For QuickBooks Online outside of the USA this behavior differs a little in that other countries support a different set of tax does (e.g. GST, HST, PST, etc.)

Answer 2

For US Quickbooks organisation/company, tax rates is handled differently. You need to create or add separate logic for US Locale:

See below from quickbooks US documentations:

https://developer.intuit.com/app/developer/qbo/docs/develop/tutorials/manage-sales-tax-for-us-locales

And this is the non US documentation which was your code followed:
