The draft e-invoicing Data Dictionary has been distributed to selected taxpayers to support early system readiness and feedback before the nationwide mandate.
The document outlines mandatory invoice data fields, business validation rules, and reporting requirements that will apply under Oman's e-invoicing framework.
The release aligns with Oman's phased approach to e-invoicing, with the Fawtara system scheduled to begin onboarding from August 2026.
By publishing draft specifications early, the Tax Authority is enabling businesses and service providers to begin technical analysis, ERP upgrades, and integration planning.
Oman's move reflects a broader regional trend across the GCC toward structured e-invoicing, real-time reporting, and increased tax transparency.
