- Oman will implement e-invoicing starting August 2026, with 100 large taxpayers selected for Phase 1.
- The Oman Tax Authority released a draft e-invoicing data dictionary in November 2025 for consultation and held workshops to explain its use.
- The data dictionary standardizes invoice data, defines business terms, business rules, and code lists for compliance and interoperability.
- Oman’s framework aligns with the PEPPOL model but includes Oman-specific requirements; formal adoption of PEPPOL is still under discussion.
