Usage

1. Create a tax group named “Ecotaxes”. The sequence must be lower than other tax groups.

   • Set the Preceding Subtotal field to “Without Ecotax”.

2. Create two taxes named “Fixed Ecotax” and “Weight-Based Ecotax”.

   • Check the Ecotax checkbox.

   • Set the correct Python code:

     • For the fixed ecotax:

       result = quantity and product.fixed_ecotax * quantity or 0.0

     • For the weight-based ecotax:

       result = quantity and product.weight_based_ecotax * quantity or 0.0

   • Check the Included in Base Amount option.

   • The sequence for Ecotax must be lower than the VAT tax.

3. For VAT taxes, check the Base Affected by Previous Taxes? option.

4. Add an ecotax classification via the menu Accounting > Configuration > Taxes > Ecotax Classification.

   • The ecotax classification can be either a fixed ecotax or a weight-based ecotax.

   • Ecotax classification information can be used for legal declarations.

   • For the fixed ecotax, the ecotax amount is used as a default value, which can be overridden on the product.

   • For the weight-based ecotax, define one ecotax by a coefficient applied to the weight (depending on the product’s materials).

   • Set the appropriate tax in the Sale Ecotax field.

5. Assign one or more ecotax classifications to a product.

   • The ecotax amount can also be manually overridden on the product.

Known issues / Roadmap

Since an update in Odoo https://github.com/odoo/odoo/commit/13e9833e0bc809a26843890363586f61a37d061c the case with ecotax as tax included and another tax included does not work anymore. The ecotax tax should only be used along with price excluded tax, or be configured as price excluded itself.
