This guide provides an overview of e-Invoicing requirements in Oman, including the legal framework, the use of the Oman e-Invoicing platform, compliance obligations, and key reporting considerations. It is intended to assist businesses that issue or receive invoices for transactions subject to VAT in Oman.
Oman’s e-Invoicing regime, established under Sultani Decree 151/2020 and Executive Regulations Decree 121/2020, was introduced by the Oman Tax Authority (OTA) to strengthen VAT compliance following VAT’s 2021 rollout. Implementation is phased, starting with large taxpayers, and requires invoices to follow a standardized data model with unique identifiers, transmitted directly or via OTA-certified platforms. Covering both B2B and B2C transactions, the framework enables real-time VAT monitoring, mandates 10-year electronic archiving, and imposes penalties for non-compliance.
Implementation is phased, starting with large taxpayers.
4 Phases:
Pilot Phase: 100 Large taxpayers (Aug 2026)
Phase 1: All large taxpayers with annual supplies exceeding OMR 5 million (1 April 2027)
Phase 2: All remaining taxpayers and SME’s (1 October 2027)
Onboarding Phase: B2G (Proposed February 2028)
B2B: Real time
B2C: 24- hours
Failing to comply with the e-invoicing mandate is regulated by Article 202 of the VAT law.
