Hello Joan, Thanks for such a good bug report.
Its difficult to produce but I can reproduce this issue on only 6.0 but on 6.1 as well as on trunk this issue is resolved and working fine. On 6.1 and trunk taxes calculated respective sequence, So this issue only affected to 6.0 stable version. For this type of issue If you have a support and maintenance contract with us then you can contact our OPW team at [email protected] . Thank you! ** Changed in: openobject-addons Status: New => Won't Fix ** Summary changed: - Tax sequence not respected + [v6]Tax sequence not respected -- You received this bug notification because you are a member of OpenERP Indian Team, which is subscribed to OpenERP Addons. https://bugs.launchpad.net/bugs/1059581 Title: [v6]Tax sequence not respected Status in OpenERP Addons (modules): Won't Fix Bug description: When the computed amount of a tax must be included in another tax computation (two or more taxes in an invoice), sometimes the result is incorrect because the tax sequence is not maintained. For example, in Spain, in some cases IRPF tax, that decrease the total amount of the invoice (for example 2%) must be computed including VAT. VAT is configured as include in base. If you have a invoice with base amount 100, it is not the same doing: 1- 100 - IRPF 2% + VAT 21% = 119 2- 100 + IVA 21% - IRPF 2% = 118,58 When computing taxes order is not being taken into account. I attach a patch that resolves this problem.
