Oman Advances Fawtara Rollout as April Marks Shift to August Go-Live
On 1st April 2026, the Oman Tax Authority (OTA) launched the first release of the Fawtara portal, formally initiating the Service Provider Registration phase. This moves the programme into implementation, with the Fawtara portal now live for service provider onboarding and integration.
Alongside the portal launch, OTA issued the Service Provider Registration Manual (v1.0), outlining technical, security and integration requirements. Providers must demonstrate capability to process structured e-invoices (UBL/XML with embedded PDF) and connect into Oman’s Peppol-aligned five-corner model. Service providers that qualify as accredited service providers will act as the primary exchange layer.
The April update did not finalise all technical specifications. Core elements such as the data dictionary and business rules remain under refinement, with OTA continuing to iterate based on feedback from pilot participants and service providers. The framework is therefore defined, but not yet fully locked.
At the same time, OTA reaffirmed the core architecture: a decentralised five-corner model.
April also signals the start of active onboarding and integration. Testing, provider accreditation and technical workshops are now underway, supported by a rollout checker tool allowing businesses to confirm when they are required to onboard ahead of the August 2026 Phase 1 mandate.
