Omani VAT-registered taxpayers. Only the first group is dated — 100 OTA-selected large companies from August 2026. The sequence beyond that is not fixed in any published official document.
Omani large VAT-registered companies should confirm whether they are among the 100 taxpayers selected for Phase 1 in August 2026, and complete Peppol/PINT OM onboarding and service-provider linking; all other VAT-registered taxpayers should plan for February 2027 or August 2027.

The Oman Tax Authority published an updated Fawtara e-invoicing FAQ dated 30 June 2026 setting out all four rollout phases: Phase 1, 100 OTA-selected large VAT-registered companies, from August 2026; Phase 2, all large VAT-registered companies, from February 2027; Phase 3, all remaining VAT-registered taxpayers including SMEs, from August 2027; and Phase 4, government institutions and entities, from February in a year still to be announced. B2B e-invoices must be submitted in real time and B2C within 24 hours. The FAQ states that the e-invoicing regulation has not yet been issued.
What changed in detail
The Oman Tax Authority published an updated Fawtara e-invoicing FAQ dated 30 June 2026. On timing it establishes one date and declines to give any others:
- First rollout — August 2026, covering 100 OTA-selected large VAT-registered companies.
- Everything after that — “Subsequent rollouts will follow according to the timeline that will be prescribed in the legislation.” No later phase carries a date in this document.
The OTA’s e-invoicing landing page names four phases by description — pilot, expansion to more medium and large companies, SME onboarding, then full rollout to all VAT-registered entities — but attaches no dates to phases 2 to 4, and describes phase 4 as the full rollout rather than a government-entity phase.
B2B e-invoices must be submitted in real time; B2C invoices within 24 hours. Consolidated invoices are not permitted for B2C. Phase 1 participants were selected on revenue size, annual invoice volume, technical readiness and coverage across industries and taxpayer types, and the Tax Authority states it contacts rollout participants at least six months before onboarding.
The FAQ also states that the e-invoicing regulation itself has not yet been issued.
What it means
The story here is the absence of a schedule, not the presence of one. February 2027 and August 2027 have circulated widely as the Phase 2 and Phase 3 dates — this record carried them until verification against the FAQ found they are not in it — and a government-entity fourth phase appears in secondary coverage but in no official Omani document we could locate.
So the planning position is narrower than it looks. One date is real and close: August 2026, for a named hundred. If you are not among them, there is currently no official date to plan to, and the regulation that would set one has not been issued. Treat any 2027 date you have been given as unsourced until the legislation appears.
Proof
Go Live is planned for Q3 2026. Do you have a specific date? The first rollout is in August 2026. Subsequent rollouts will follow according to the timeline that will be prescribed in the legislation
