Starting from May 1, 2026, the Belgian withholding obligation regulations will be extended for contractors, cleaning companies, and security firms. In addition to tax and social security debts (RSZ), outstanding self-employed social contributions (RSVZ/INASTI debts) will also need to be taken into account.

We use Odoo for our administration and invoice processing, and we would like to know whether there is currently — or if there are plans for — a feature that can automatically verify withholding obligations for suppliers or subcontractors.

More specifically, we are interested in functionalities such as:

• an automatic check through the official withholding obligation database/checkinhoudingsplicht system;
• warnings during supplier invoice processing;
• automatic calculation of withholding percentages;
• support for Belgian regulations concerning tax, RSZ, and RSVZ/INASTI debts.

As this verification will become increasingly important from May 2026 onward in order to avoid liability risks and penalties, we would appreciate knowing whether an existing module, integration, or roadmap item already exists within Odoo for this purpose.

Thank you in advance for your feedback.
