AI-generated from the code · Odoo 18.0

This module helps you set up EU One-Stop-Shop (OSS) VAT taxes and fiscal positions for distance sales to EU consumers. A wizard creates the correct sales taxes and automatic B2C fiscal positions for each EU country you sell to.

The module adds a setup wizard called "Setup EU OSS OCA Taxes" that you can open from Accounting settings, under the EU OSS OCA section, via the "Add new taxes" button.

In the wizard you choose the company, the EU countries you sell to ("EU Customers From"), whether prices include tax, and which of your existing sales taxes correspond to the general, reduced, super-reduced and second super-reduced rates. Countries already covered are shown as "Already Supported".

When you click "Create Fiscal Positions and Taxes", the module creates, for each selected country, the OSS sales taxes at the rates stored in the module's rate table (one rate per EU country), grouped under tax groups named like "OSS VAT x%", and an automatic B2C fiscal position named "Intra-EU B2C in <country> (EU-OSS-<code>)". If a matching fiscal position already exists, its OSS tax mappings are refreshed instead of duplicated.

It also adds an "OSS OCA" checkbox on fiscal positions and an "Oss Country" field on taxes, and stores the official EU VAT rates per country (general, reduced, super-reduced, second super-reduced). Access is read-only for invoicing users and full for accounting managers.
