Issue UBL-44 : Add a WithholdingTaxAmount to LegalMonetaryTotal

All,

During the comment period for UBL 2.2 a request was made to align the invoice and creditnote around withholdingtax (UBL-18) [1]. The request to add the cac:WithholdingTaxTotal as an optional element was accepted to bring  the billing documents in line with each other.

In that request there was also a possible need to add a “total” to the LegalMonetaryTotal element for withholdingtax. This was separated out as an individual issue UBL-44 [2].

In order to resolve that request we need to discuss the following questions:

·
Do we need to add this element?
·
Is there a possibility that you can have multiple WithholdingTaxTotals on a billing document? and maybe even need to pay that to separate "entities"? and how do we represent that in LegalMonetaryTotals.
·
Do we need to separate out the WithholdingTax also with an inclusive/exclusive amount just like “normal” tax?
·
How does that relate to the rest of the calculation logic?

I would like to propose that we can discuss this issue on this list (ubl-post-award) until next week Tuesday, and then make a decision if we feel that there is enough consensus to add this element and enough clarity how  it should be used, and how it impacts the calculations.
