E-invoicing in Oman: CTC 5-corner model, PINT OM, Fawtara Portal and Peppol routing.
Oman is preparing mandatory e-invoicing based on the Peppol network. The country follows a CTC 5-corner model that closely resembles that of the UAE, but distinguishes itself through a broader scope (including B2C) and a separate consent mechanism via the Fawtara Portal.
Please note: the Peppol Authority Specific Requirements (PASR) for Oman are currently in member review (until 20 April 2026). The specifications have not yet been formally approved. The information on this page is based on the current PASR proposal and may change.
The Omani architecture follows the Peppol 5-corner model, comparable to the approach in the UAE. Invoices are exchanged in a decentralized way via Peppol, while tax data is simultaneously reported to the government. Each party has a clearly defined role:
As with the UAE, both the sender's Access Point (C2) and the recipient's Access Point (C3) send a Tax Data Document to the tax authority. The Oman Tax Authority therefore receives invoice data from both sides, enabling a full match.
For each invoice, the Access Point generates a Tax Data Document (TDD OM) containing the VAT-relevant data. This document is sent to the Oman Tax Authority (C5) in parallel with the invoice exchange. The TDD does not contain the full invoice content, only the data the tax authority needs for verification.
Message Level Status (MLS) is set to ALWAYS_SEND for all documents. This means that every invoice exchange and TDD report triggers a status confirmation in return.
The PASR proposal specifies the following maximum delivery times:
Metadata retention is 12 months. SMP registration is processed within 3 working days, deregistration within 1 working day.
PINT OM is the Oman-specific variant of the Peppol International Invoice, based on EN 16931 with additional fields for the Omani tax system. The format supports three document types: invoices, credit notes and self-billing documents. With self-billing, the buyer issues the invoice on behalf of the supplier.
The Peppol identifier for Omani organisations is EAS code 0248 (Oman VATIN): a 12-digit VAT number issued by the Oman Tax Authority.
The Fawtara Portal is the central eInvoicing portal of Oman. This platform fulfils two functions:
Registration. All Peppol participants in Oman register via the Fawtara Portal. The portal manages the mandatory central SMP where organisations register their Peppol endpoint.
Consent mechanism. This is a key difference compared to the UAE. In Oman, an organisation must give explicit consent via the Fawtara Portal to participate in the e-invoicing system. This consent mechanism governs the relationship between the organisation and its Service Provider.
The PASR proposal sets strict requirements for Service Providers wishing to operate in Oman:
The introduction of the Omani e-invoicing system proceeds in four phases:
The phased rollout begins after approval of the PASR. The exact start dates will be determined by the Oman Tax Authority.
Please note: the scenarios below are based on the PASR proposal that is still under review. The definitive rules may differ.
Do you invoice companies or government bodies in Oman? Once the PASR is approved, Peppol offers a direct and compliant route. Invoices are routed via the Peppol network with automatic TDD reporting to the Oman Tax Authority.
Do you receive invoices from Omani suppliers? As a Peppol participant, you are automatically reachable for Omani suppliers once the system becomes operational.
Do you have a branch in Oman? Then you should register via the Fawtara Portal in good time and connect to an accredited Peppol Service Provider.
Oman will be reachable via the Peppol network once the PASR is approved. Direct accreditation as a Service Provider in Oman is unlikely for eConnect at this time due to the strict local establishment requirements. A local partner strategy is therefore the most probable route.
Once the PASR is approved, Oman will be reachable via the Peppol network. Due to the strict local accreditation requirements, eConnect is exploring options, with a local partner strategy as the most likely route.
