AI-generated from the code · Odoo 14.0

Create Thai withholding tax certificates from payments or journal entries, with automatic tax lines, status workflow, and substitution of old certificates.

This module adds a dedicated Withholding Tax Certificate document to Odoo, used for Thai withholding tax reporting. Users can create certificates directly from a payment or a journal entry using the "Create Withholding Tax Cert." action available on those documents. A wizard asks for the withholding tax accounts, the income tax form (PND1, PND3, PND3a, PND53) and the type of income; the certificate is then pre-filled with the supplier, date, tax IDs and one line per withholding tax journal item, showing base amount, tax percentage and tax amount.

Certificates follow a simple workflow: Draft, Done and Cancelled, with buttons to set to draft, mark as done or cancel. When a certificate is marked as done and it substitutes an older one, the old certificate is automatically cancelled and a message is posted on it. A control ensures that base amount, percentage and tax amount always match.

A "WT Certs" button appears on payments and journal entries that have certificates, opening the related list. A new "WT Certificates" menu is available under Accounting > Vendors, with search filters by payment or journal and grouping by tax form and tax payer. Certificates are restricted to the user's allowed companies.
