Regulatory Changes in Odoo
Oman rules change. This page lists what we are watching, what is already applied, and what to do in Odoo when each change takes effect.
To apply a change, a user with accounting rights signs in to Odoo and changes the Oman parameters. The customer does not do this. Status checked on 20 October 2026.
How to apply a change
- Read the instrument: the decision number, the date it is signed and the date it takes effect.
- If the change is a rate, a percentage or a date that exists as a parameter, open Invoicing > Configuration > Oman parameters and change the value (see Oman Parameters). Do it before the first payroll that the change affects.
- Open Oman parameter changes and check that the change is logged.
- If the change is a new rule or a new tax and no parameter exists, do not edit salary rules or taxes yourself. Ask FiscFort support.
- If the change affects a filed period, tell the customer and do not reopen the period without a reason.
