auto_awesome What this module does
AI-generated from the code · Odoo 18.0Adds Mexican ISH, ISN, and IEPS 200% taxes to Odoo's Mexican accounting localization, so you can apply these taxes on sales and purchases and post them to the correct accounts.
This module extends the Mexican accounting localization by adding three groups of taxes that are not included by default.
- ISH (lodging tax): available at rates from 0% to 5% in half-point steps, for both sales and purchases. These taxes use cash basis, meaning they are only accounted for when the invoice is paid.
- ISN (state payroll tax): available at 1%, 2%, 3%, and 4%. These are not tied to sales or purchases (type 'none') and post to the expense account 'State payroll tax' (603.29.01).
- IEPS 200%: a special tax on production and services at 200%, for both sales and purchases, also on a cash basis.
The module also creates the necessary accounts, such as 'ISH pending payment' (119.09.01) and 'Per diems and travel expenses' (603.49.001), and tax groups for ISH, ISN, and IEPS 200%. These taxes become available when you install the Mexican chart of accounts, and you can select them on invoices, bills, and other accounting documents. The taxes are configured with the correct tax type and factor type for Mexican reporting.
