Hello, i am currently using OpenERP v7. I have the "Canada - Accounting l10n_ca" module installed. I am currently prepping OpenERP do to business in Quebec, Canada where the tax rate are 9.975% + 5% (Provincial and federal)

I can properly do invoices in the accounting tab, taxes are calculated properly. The problem come when i create a sale with the POS, taxes are charged at 100% !!?! See example: tinypic.com/view.php?pic=32zm8nm&s=5

But when i return to the sale history made by the POS (Point Of Sale->Orders) I can see that the order was properly taxed See picture: tinypic.com/view.php?pic=jhx283&s=5 Its a weird situation.

The only related thread i have found is this one but no answer and also different version: help.openerp.com/question/13597/how-to-configure-correctly-taxes-calculation-in-pos-61/

I have googled and looked thru the old forum but no luck. Please, dont be that guy that post a google search link as an answer!

Any help is truly appreciated!

Hello Patrick (again),

the problem is related to the POS module itself. POS has its own method to compute taxes and does not involve dependant child taxes. => it should rely on the openerp accounting module.

This can be viewable in the following file : point_of_sale/static/src/js/models.js, lines 508 to 531.

I opened a bug, hope OpenERP SA will be reactive : https://bugs.launchpad.net/openobject-addons/+bug/1231574

Regards, Marc
