Oman launches a Fawtara rollout checker so taxpayers can confirm their wave

The Oman Tax Authority published a readiness-checker tool letting taxpayers confirm which Fawtara wave applies to them. It is a small thing that solves a real problem: Decision 189/2026 splits the population at OMR 5 million of annual supplies — above that, 1 April 2027; at or below, 1 October 2027 — and many businesses near the line were unsure which side they fell on, particularly those whose supplies vary year to year. The mandatory pilot with roughly 100 large taxpayers has been running since 1 August 2026 and voluntary participants operate under identical technical rules.

Oman puts its e-invoicing dates in law — Decision 189/2026 sets 1 April and 1 October 2027

Oman amended the VAT Executive Regulations through Decision No. 189/2026, giving Fawtara legal ground and replacing the indicative roadmap with two statutory deadlines. Taxable persons with annual supplies above OMR 5 million must comply from 1 April 2027; everyone at or below that threshold follows on 1 October 2027. This supersedes the earlier four-phase plan that had circulated with February and August 2027 dates, so anyone planning against those is working to the wrong calendar. The decision also settles what counts: invoices must be issued, transmitted and retained in an approved structured electronic format, and paper, ordinary PDFs and emailed invoice images explicitly do not qualify as electronic tax invoices. The mandatory pilot with roughly 100 large taxpayers has been running since 1 August 2026, and companies outside that cohort may join voluntarily under identical technical rules.

Oman launches the mandatory Fawtara pilot with the first 100 large taxpayers

The Oman Tax Authority launched the mandatory pilot phase of Fawtara on 1 August 2026 with a first cohort of 100 selected large VAT-registered taxpayers, already notified by OTA. The pilot is mandatory for all B2B taxable transactions of participating companies, not a voluntary sandbox. Oman runs a 5-corner Peppol model on three specifications: PINT BIS Billing Oman 1.0.1 for invoices, PINT BIS Self-Billing Oman 1.0.1, and TDD Oman 1.0.1 for tax data reporting to the central Fawtara platform. Where a buyer is not yet connected, the supplier still reports tax data to Fawtara and provides the buyer a readable copy — PDF or paper carrying a QR code. OTA became a Peppol Authority on 7 January 2026, making Oman the third GCC country to mandate e-invoicing after Saudi Arabia and the UAE. Companies outside the initial cohort are encouraged to join voluntarily ahead of the next phase.

Oman publishes PINT-OM and slashes ASP capital requirement 10x

OTA confirmed Fawtara key dates and major market changes. PINT-OM specification was published via OpenPeppol in April 2026, covering invoices, credit notes, self-billing and the Oman Tax Data Document (TDD). The ASP paid-up capital requirement was reduced from OMR 60,000 to OMR 6,000 — a 10x reduction opening the market to smaller technology firms and regional players. Phase 1 (top ~100 large taxpayers) goes live Aug 2026; Phase 2 Feb 2027 (all large taxpayers); Phase 3 Aug 2027 (all VAT-registered).

Oman OTA opens Fawtara sandbox; ASP accreditation registration imminent

The Oman Tax Authority has confirmed its e-invoicing rollout roadmap. A sandbox/developer environment is available from February 2026 and Access Point accreditation registration opens in May 2026. Phase 1 starts August 2026 for ~100 of the largest VAT-registered taxpayers. Oman uses the Peppol 5-corner model with the OTA acting as the Oman Peppol Authority.
