What Decision 189/2026 asks of you
The OMR 5 million rule
Decision 189/2026 tests annual taxable supplies against OMR 5 million. Above OMR 5 million, you go live on 1 April 2027. At OMR 5 million or less, you go live on 1 October 2027, so a business at exactly OMR 5 million is in the October group. Confirm how your supplies are measured with the Tax Authority.

Why the four-phase plan vanished
The Tax Authority published a phased approach first. Decision 189/2026 replaced it entirely with the two dates above. Older guides still mention phases. Confirm your date against the Decision and the Tax Authority's FAQ, not cached articles. Read: Oman e-invoicing timeline
PINT OM and your build schedule
Oman e-invoices are UBL 2.1 XML (PINT OM v1.0.1). The format covers invoices, credit notes and self-billing. PDFs don't count. Mapping your ERP fields to PINT OM is the longest workstream: field mapping, build, sandbox and test take five months of the nine-month plan. Read: Oman e-invoicing formats: PINT OM, UBL 2.1 and XML
Why the plan is nine months long
Nine months lets you run tasks in sequence: team formation, gap assessment, provider selection, data clean-up, UBL build, sandbox testing, full test cycle, volume test, training, cut-over. Shorten the runway and tasks overlap. The planner shows which milestones are already behind on day one. Read: Oman Fawtara e-invoicing: what businesses need to know
Oman e-invoicing FAQs
When does e-invoicing become mandatory in Oman?
Decision No. 189/2026 sets two dates. Businesses with taxable supplies above OMR 5 million go live on 1 April 2027. Every other VAT-registered business goes live on 1 October 2027.
How do I know whether I am above OMR 5 million?
The Decision tests annual taxable supplies against OMR 5 million. Above OMR 5 million, you go live on 1 April 2027. At OMR 5 million or less, you go live on 1 October 2027. Confirm how your supplies are measured with the Tax Authority.
What happened to the earlier four-phase timeline?
Decision 189/2026 replaced it. The rollout is now the two dates above. Articles and vendor pages from before August 2026 may still show the old phases.
What format do Oman e-invoices use?
UBL 2.1 XML under PINT OM, the Omani Peppol International Invoice profile. Version 1.0.1 defines Billing for invoices and credit notes, Self-Billing, and the Tax Data Document that reports to the Tax Authority. A PDF can travel with the invoice, but it is not the e-invoice.
Do I need an accredited service provider?
Yes. Fawtara exchanges invoices through service providers accredited by the Tax Authority, and they relay the tax reporting too. Accreditation is under way now. Choosing and contracting a provider sits at month seven in the plan, before data clean-up and build start. Complyance is an approved Fawtara service provider.
Can we go live before our date?
Yes. About 100 companies started using Fawtara voluntarily in a pilot from August 2026, and early adoption is open to other businesses too. Pilot companies are encouraged to go live before their mandatory date. Your service provider can tell you how early onboarding works.
Does the planner store or send my data?
Your annual supplies, start date and ticks stay in this browser's local storage, so the plan is there when you come back. Nothing is sent while you plan. When you download the plan as Excel or PDF, the details you enter in the download form go to Complyance with a short summary of your plan (go-live date, supplies band and progress), so our Oman team can follow up. Clearing site data resets the planner.
Is this tax advice?
No. We built the planner from the published Decision and the Tax Authority's guidance. Confirm your threshold position and go-live date with your tax adviser or the Tax Authority.
