Re: Want tax move line with zero balance, possible? (odoo 13)

I agree that they are not needed and there is a work around to work with them, but IMHO, as there is already a tax_base_amount stored field on aml, it would be much easier to get taxes and base amounts just filtering aml with "tax_line_id", and on that aml you already have the balance and the tax amount. That is already in odoo, the only problem is for zero taxes.

IMHO, with the current approach:
* it's litle ugly how "_compute_invoice_taxes_by_group" simulate the zero taxes
* more code needed for getting tax amounts on electronic invoice / tax declaration
* more code needed on the "tax engine"
You can't analyse directly any odoo model to get this info, is not visual. Just having those lines would make much easier to get visual information about the taxes from everywhere (on the invoice itself, checking the aml on journal items, menus, etc).

But yes, I agree it is not needed, I just believe it would make thing much easier and nicer. But still, is an odoo decision, I wouldn't make any module to change that behaviour .

We also have zero tax lines in Belgium and no need for aml with debit/credit 0.

I support Pedro here, with correct reports you solve the issue.

I think the need of that aml with 0 is because the tax engine / exporter is not considering the amls for the base on the said field. We are doing that way on our tax engine for Spanish legislation without problem:



The overall logic is:


- There are amls with tax_line_id field with that tax: the tax fee.

- There are amls with tax_ids field with that tax: the tax base.
