Oman E-Invoicing Rollout: Key Dates, Fawtara Portal Launch, and Implementation Phases

• Oman is implementing a nationwide e-invoicing system through a four-stage rollout, with the Fawtara Portal as the central platform.
• Service provider registration for the Fawtara Portal opens in Q1 2026, with a test environment available in Q2 2026, and full e-invoice exchange starting in Q3 2026.
• The 100 largest VAT-registered companies must comply with e-invoicing from August 2026, with other large and remaining VAT-registered companies phased in by February and August 2027, respectively.
• Government entities will be included in a later, yet-to-be-scheduled phase.
• The final e-invoicing data dictionary has not been released, but once available, it will clarify requirements and business rules for all taxable persons.
