When does Phase 1 of Oman e-invoicing start?
Table of Contents
Phase 1 started in August 2026.
This phase is not a general obligation for every large taxpayer. It is the initial rollout involving 100 selected large VAT-registered companies. The Oman Tax Authority has indicated that selection is based on factors such as revenue size, annual invoice volume, and technical readiness.
Businesses selected for Phase 1 should therefore treat their communicated rollout date as their implementation deadline and complete the required technical and onboarding preparations accordingly.
Key points
- Phase 1 begins: August 2026.
- Target group: 100 selected large VAT-registered companies.
- Selection is based on multiple readiness and business criteria.
- Businesses outside Phase 1 may voluntarily adopt early.
