Tax Calculations in Quotation Rounding problem

I am trying to setup so that when a Quote or Sales Order is created OpenERP should calculate the Tax as follows: 1. Excise (@ 10.3%) on Total Amount 2. VAT (@ 5%) on the Excise amount calculated.

Looking at above scenario if the bill amount is 10000.00 then Excise should be 1030.00 (@ 10.3% of 10000.00 ) and VAT should 551.50 (@ 5% of (10000.00 + 1030.00 = 11030.00)).

Totaling above should give us 11581.5 (which is 10000.00 + 1030.00 + 551.50).

But what we get in OpenERP is 11580.00 which is wrong. Here is the screen shot: image description

Please help solve this problem.

TIA

you can create a new inherit Module "J'ai mis un champ libre pour saisir l'accise 10.3%" car il faut d'autres contrôles pour l'exécuter automatiquement. Tu dois faire pareil pour la facture.

NB: Faut laisser la Taxe a ZERO. car le calcul TVA est sur les lignes pas sur le Total.

You mean to say that this is the only way out. Can't we solve this by setting up the TAX part in some way? I think bug is a serious show stopper!

I know this is an old question but we have a similar problem. I tried to describe it in https://github.com/odoo/odoo/issues/9417. Maybe there was some update in the meantime so we don't need an additional module.
