Regulatory updates - Oman

On September 25, 2025, Oman’s Tax Authority (OTA) shared additional information via email with the 100 companies selected to participate in the pilot phase of the e-invoicing (Fawtara) Program. The communication outlined plans for a 5-corner model that will require invoice exchange through OTA-accredited service providers, as well as an implementation timeline:

• November 2025: Publication of e-invoicing specifications on OTA’s official website;
• December 2025: Release of Standards for Service Providers (SP) and the beginning of e-invoice workshops;
• February 2026: Launch of a developer’s portal for SPs;
• May 2026: Start of registration and accreditation process for SPs; and
• August 2026: Planned go-live of the pilot phase.

Expected completion of the phased rollout of the e-invoicing mandate has been set to August 2028. Additional details are yet to be released by the OTA.

The Oman Tax Authority (OTA) has established the criteria for selecting the initial 100 companies to participate in the upcoming e-invoicing mandate. The announcement highlighted six key criteria, although specific details were not disclosed:

• Size of the business and transaction volume
• Representation across diverse economic sectors
• Level of technical readiness
• Track record of tax compliance
• Willingness to engage in the trial phase
• Geographic distribution across various regions in Oman

Details regarding the onboarding timeline for these companies have not yet been shared, but further information is anticipated soon.

 Stay tuned with Pagero for the latest updates as this initiative progresses.

The Oman Tax Authority (OTA) originally planned to introduce e-invoicing in 2024. However, the rollout was postponed until further notice.

As in May 2025 the OTA has signed an e-invoicing agreement with Oman Telecommunications Company (Omantel), this sends a strong signal that the earlier plans are being re-engaged. This strategic partnership sets the foundation for an advanced e-invoicing ecosystem in Oman. We should get more information around further details, such as the planned CTC model, implementation timelines and technical specifications. But we can probably already now say with a fair degree of certainty that the earlier anticipated timelines for early-2026 will not remain.

Stay tuned with Pagero for updates as this initiative continues to unfold.

The Oman Tax Authority (OTA) has issued Decision No. 456 of 2022, amending the VAT Executive Regulations.

What are the key changes?

Issue time of the tax invoice

The previous regulation did not specify a timeline for the tax invoice issuance. Now, the law states that tax invoices must be issued within 15 days following the various cases stipulated in article (143).

Penalties

Article (202) of the “Administrative Sanctions” was amended to include that failing to issue valid tax invoices within the given timeframe may lead to penalties from OMR 500 to OMR 5 000 (ca. EUR 1320-13 200).

Exemption from VAT

Article (79) of the “Tax-exempt Supplies” was extended to enclose financial services, such as loans, credits, life insurance services, etc.

Electronic invoicing

A new paragraph has been added to article (1) to define the Electronic Tax Invoice as “a tax invoice that is generated in a structured format by electronic means, has the details specified in the VAT Executive Regulations at the minimum and shall comply with any other requirements that may be stipulated by the tax authority”.

Failure to issue the electronic tax invoice as per requirements to be determined by the tax authority may also lead to penalties from OMR 500 to OMR 5 000.

Impact and important considerations

The amendments also touch upon several vital areas, such as the recovery of input VAT, place of supply for the provision of telecommunication services and more. Businesses operating in Oman are highly encouraged to look at the overall amendments and carefully evaluate their VAT position to determine what impact these changes might have from the regulatory perspective. Moreover, resident taxpayers should be aware that Oman has set sights on introducing mandatory e-invoicing.

Implementation timelines and the scope of the mandate are expected to be announced in the near future. Stay tuned with Pagero.  

On Sunday, The Omani Tax Authority issued Decision No. 53/2021 promulgating the executive regulations for the Value Added Tax Law, based on the VAT Law issued by Royal Decree No. 121/2020.

The regulation consists of 13 chapters with a total of 211 articles.
