Mandate Overview
The mandate
Oman's Tax Authority (TA) has confirmed plans to introduce a phased e-invoicing mandate, with a voluntary onboarding phase opening in 2024 and mandatory waves anticipated to begin in 2025-2026. As of early 2026 the formal technical specifications and onboarding wave thresholds have not been published in binding form, and timelines have shifted from earlier industry expectations. Oman's framework is widely anticipated to align with the Saudi ZATCA Fatoora two-phase model given the GCC's coordinated approach to digital tax administration, but the TA has the latitude to customize. Businesses should monitor TA communications closely.
