Fawtara readiness

Find your e-invoicing date

Electronic tax invoices become mandatory in Oman on 1 April 2027 for taxable persons whose annual supplies exceed OMR 5,000,000, and on 1 October 2027 for everyone else, under Tax Authority Decision No. 189/2026. The date depends on VAT registration and annual supplies, not on the trade you are in.

What changed in August 2026.

How Fawtara arrived

The Oman Tax Authority was approved as a Peppol Authority on 7 January 2026. The technical specification, PINT OM, was published in April 2026 and uses UBL 2.1 XML.

A voluntary pilot of roughly 100 selected large taxpayers began in late August 2026, and Decision 189/2026 was published on 9 August 2026. Nothing is legally required of anyone before 1 April 2027.

How an invoice actually travels

Oman uses the Peppol five-corner model. Your invoice goes to your accredited service provider, which validates it, passes it to your customer’s service provider, and reports it to the Tax Authority.

There is no direct connection from your own system to the Tax Authority. That is the part most often misunderstood, and it decides what software you actually need.

What an electronic tax invoice is not

An electronic tax invoice is a structured data file exchanged through an accredited service provider. A paper invoice is not one. A scan of a paper invoice is not one. A PDF sent by email is not one either, however correct the document inside it looks.

How long records are kept

Tax records are reported to be kept for 10 years under Article 70 of the VAT Law, and for 15 years where they relate to real estate.

The penalty range

Failing to issue a compliant tax invoice carries a penalty of OMR 500 to OMR 5,000 under Article 202 of the VAT Executive Regulations as amended by Decision 456/2022, with possible suspension of activity for a serious or repeated breach.

What is not settled yet

Digital signature and hash guidance is expected. Exempt supplies may be brought into scope. Decision 189/2026 does not address a separate phase for government entities.

These are open questions rather than gaps in this page, and anyone telling you otherwise is ahead of the published guidance.

Questions

When does Oman e-invoicing apply to my small business?
On 1 October 2027, if your annual supplies are OMR 5,000,000 or below, which covers almost every Omani SME. Businesses above that threshold start on 1 April 2027. Both dates come from Tax Authority Decision No. 189/2026, published on 9 August 2026.
Is an emailed PDF a valid e-invoice in Oman?
No. An electronic tax invoice under this framework is a structured data file exchanged through an accredited service provider. A PDF sent by email is not one, and neither is a scan of a paper invoice, however complete the document looks.
Do I send invoices to the Tax Authority myself?
No. Oman uses the Peppol five-corner model, so your invoice goes to your accredited service provider, which passes it to your customer’s provider and reports it to the Tax Authority. A direct connection from your own system is not permitted.
What is the penalty for not issuing a compliant tax invoice?
OMR 500 to OMR 5,000 under Article 202 of the VAT Executive Regulations as amended by Decision 456/2022, with possible suspension of activity for a serious or repeated breach. The obligation to issue a compliant invoice predates Fawtara.
Does the four-phase rollout still apply?
No. The timetable announced before August 2026 no longer carries legal effect. Decision 189/2026 replaced it with a single test based on annual supplies, so your date comes from your own turnover rather than from a group assigned to you.
Are exempt supplies covered?
Exempt supplies are reported to sit outside the scope of electronic invoicing today, and the Tax Authority has indicated this may change. Zero-rated supplies are reported to be in scope: the rate is zero, the obligation is not.
Is Yusrin accredited by the Oman Tax Authority?
No. Yusrin is not accredited and does not transmit invoices to the Fawtara platform. Yusrin produces tax invoice documents carrying the mandatory contents, and transmission goes through an accredited service provider.
Does this check send my answers anywhere?
No. The check runs entirely in your browser. Nothing you select is transmitted, stored or logged, and sharing the tool posts only its address, never your answers.
