Corporate Lawyers Oman 2026: Authorised Manager Rules, UBO Register & OECD Top‑up Tax

Oman’s 2026 regulatory overhaul has introduced three compliance pillars that every company operating in the Sultanate must address without delay: tightened authorised manager rules under the amended Commercial Companies Regulation, a mandatory beneficial‑ownership (UBO) register, and an OECD‑aligned top‑up tax targeting multinational groups. Corporate lawyers in Oman are advising clients that the compliance deadlines attached to these reforms fall within six months of entry into force, meaning companies that have not already begun the process face mounting enforcement risk. This guide sets out the practical steps general counsels, company secretaries and inbound investors need to take, together with filing checklists, sample resolutions and a consolidated deadline calendar that can be applied immediately to corporate governance Oman 2026 obligations.

What Changed in 2026, Quick Legal Snapshot

The 2026 reform package centres on amendments to the executive regulations of the Commercial Companies Law (Royal Decree 18/2019), introduced through a series of Royal Decrees and Ministerial Decisions published in the Official Gazette. The stated objective is to align Oman’s corporate governance framework with international transparency standards, particularly the OECD’s Inclusive Framework on Base Erosion and Profit Shifting (BEPS) and the Financial Action Task Force (FATF) beneficial‑ownership recommendations.

The principal changes can be summarised as follows:

• Authorised manager rules. New fitness and qualification criteria for the authorised manager (or managers) of every commercial company, including an annual compliance certificate obligation.
• UBO register. A mandatory beneficial ownership declaration and register requirement imposed on LLCs, joint‑stock companies and branches of foreign entities.
• OECD top‑up tax. Legislative groundwork for a domestic top‑up tax aligned with Pillar Two of the OECD/G20 framework, targeting multinational enterprise (MNE) groups with consolidated revenues exceeding EUR 750 million.
• Enforcement powers. Enhanced supervision and penalty provisions granted to the Ministry of Commerce, Industry and Investment Promotion (MOCIIP) and the Financial Services Authority (FSA).

Primary Instruments and Where They Are Published

All instruments are published in the Oman Official Gazette, accessible through the Oman corporate practice area resources and the official portals listed below.

Companies are required to comply with these changes within six months of entry into force, which places the compliance deadline at 11 July 2026.

Authorised Manager Rules 2026, Who Must Comply and What to Do

The amended Commercial Companies Regulation now imposes specific fitness, qualification and residency requirements on every person designated as the authorised manager of an Omani company. All commercial companies, LLCs, single‑person companies (SPCs), joint‑stock companies and branches, must review whether their current managers and authorised signatories meet the new criteria and, if not, take corrective action before 11 July 2026.

The key obligations for corporate lawyers in Oman to communicate to clients include:

• Verify qualifications. The authorised manager must hold qualifications and experience appropriate to the company’s grade. Grade 1 and Grade 2 companies face the most stringent standards.
• Confirm residency. The authorised manager must maintain residency in Oman unless otherwise permitted by MOCIIP.
• Sign the annual compliance certificate. A new mandatory filing in which the authorised manager personally certifies the company’s adherence to the Commercial Companies Regulation provisions applicable to its grade.
• Update the Commercial Register (CR). If the authorised manager is changed, the CR entry must be updated within the period prescribed by the Regulation.
• Maintain a delegation framework. Where the authorised manager delegates signatory authority, the delegation must comply with the new rules on scope, duration and revocation.

Company Grading and Differential Obligations

The Regulation classifies companies into grades based on share capital, revenue and employee headcount. The grading determines the intensity of compliance obligations, including the level of qualification required of the authorised manager, the frequency of reporting to MOCIIP and the scope of the annual compliance certificate.

• Grade 1 (largest companies). Full annual compliance certificate, enhanced qualifications for authorised manager, mandatory external audit, detailed UBO filing.
• Grade 2. Annual compliance certificate required, standard qualifications, external audit (where applicable).
• Grade 3. Simplified compliance certificate, internal review sufficient in lieu of external audit for certain entities.
• Grade 4 (smallest companies / SPCs). Basic compliance obligations; the owner‑manager may self‑certify subject to meeting minimum qualification thresholds.

Industry observers expect the grading system to increase the administrative burden on medium‑sized companies most significantly, as many will need to upgrade their internal governance structures for the first time.

Annual Compliance Certificate, Sample Wording and Signature

For Grade 1 and Grade 2 companies, the authorised manager must sign the annual compliance certificate confirming adherence to the provisions of the Commercial Companies Regulation applicable to the entity’s grade. The certificate must be filed with MOCIIP within the prescribed period after the end of each financial year.

A practical sample board resolution authorising the filing follows:

“RESOLVED that [Name], Authorised Manager, is hereby directed to prepare, sign and file with the Ministry of Commerce, Industry and Investment Promotion the Annual Compliance Certificate for the financial year ending [date], confirming the Company’s compliance with the provisions of the Commercial Companies Regulation applicable to its grade classification, and to take all steps necessary to effect such filing within the prescribed deadline.”

UBO Register in Oman, Obligations, Filing Process and Templates

Every commercial company in Oman must now establish and maintain a register of its beneficial owners (UBO register). A “beneficial owner” is defined under the amended Regulation as any natural person who ultimately owns or controls, directly or indirectly, a prescribed percentage of the shares or voting rights in the company, or who otherwise exercises ultimate effective control over the entity.

The UBO register Oman framework requires companies to:

• Identify all beneficial owners meeting the prescribed ownership or control threshold.
• Collect and verify prescribed personal data, full legal name, nationality, date of birth, residential address, nature and extent of beneficial interest, and date on which the person became a beneficial owner.
• Maintain the register internally at the company’s registered office in Oman, available for inspection by competent authorities.
• File a beneficial ownership declaration with MOCIIP where required by the company’s grade or upon specific request from the regulator.
• Update the register within the prescribed period of any change in beneficial ownership.

Failure to establish or maintain the UBO register, or to file the beneficial ownership declaration when required, exposes the company and its officers to the penalty provisions under the Commercial Companies Regulation.

Step‑by‑Step Filing Checklist (MOCIIP / Registry)

• Step 1, Identify beneficial owners. Review shareholding structure, voting agreements and any side arrangements that confer effective control.
• Step 2, Collect prescribed data. Gather certified copies of identity documents, proof of address and details of the nature and extent of beneficial interest for each UBO.
• Step 3, Prepare the internal register. Use the template format prescribed by MOCIIP and maintain it at the registered office.
• Step 4, Draft and sign the beneficial ownership declaration. The declaration must be signed by the authorised manager or an authorised signatory.
• Step 5, File with MOCIIP. Submit the declaration through the MOCIIP e‑services portal or at the relevant MOCIIP office, together with supporting documentation.
• Step 6, Monitor and update. Establish a process for ongoing monitoring and update the register within the prescribed period of any change.

Sample Beneficial Ownership Declaration

“I, [Name], Authorised Manager of [Company Name] (CR No. [number]), hereby declare that the information contained in the attached Beneficial Ownership Register is true, complete and accurate as at [date], and that the Company has taken all reasonable steps to identify its beneficial owners in accordance with the requirements of the Commercial Companies Regulation.”

OECD Top‑Up Tax, High‑Level Impact for Inbound Investors

Oman has signalled its commitment to implementing a domestic top‑up tax aligned with Pillar Two of the OECD/G20 Inclusive Framework on BEPS. The OECD top‑up tax is designed to ensure that large multinational enterprise groups pay a minimum effective tax rate of 15 per cent in every jurisdiction where they operate. Where the effective tax rate (ETR) in a jurisdiction falls below 15 per cent, the top‑up tax mechanism imposes an additional charge to bring the rate up to the global minimum.

For Oman, which has historically maintained a corporate income tax rate of 15 per cent, the likely practical effect will be modest for most domestic operations. However, cross‑border groups with Omani subsidiaries, branches or holding structures need to assess their position carefully, particularly where:

• Tax incentives, free‑zone benefits or investment‑licence exemptions reduce the effective rate below 15 per cent.
• The parent entity is based in a jurisdiction that has already enacted an Income Inclusion Rule (IIR) under Pillar Two.
• Intra‑group transactions or passive income streams create a mismatch between accounting profit and taxable income in Oman.

Early indications suggest that Oman’s implementation will follow the OECD Model Rules closely, with the Ministry of Finance expected to issue detailed guidance addressing the interaction between the top‑up tax and existing domestic tax provisions, including the income tax regime under Royal Decree 28/2009 (as amended).

Practical Structuring Checklist for Investors

• Calculate the Omani ETR. Prepare a jurisdiction‑level ETR calculation using the OECD GloBE Rules methodology, including adjustments for timing differences and covered taxes.
• Review incentives and exemptions. Identify any tax holidays, free‑zone benefits or investment‑licence incentives that could reduce the ETR below the 15 per cent minimum.
• Map intra‑group transactions. Review transfer pricing documentation and intercompany agreements for transactions that could shift profit out of Oman.
• Assess substance. Confirm that the Omani entity has sufficient economic substance (employees, tangible assets) to benefit from the substance‑based income exclusion under the GloBE Rules.
• Coordinate with parent jurisdiction. Determine whether the parent entity’s home jurisdiction has enacted an IIR and whether a Qualified Domestic Minimum Top‑Up Tax (QDMTT) applies in Oman.

Key Compliance Deadlines, MOCIIP Filings and Penalties

The consolidated deadline calendar below sets out the critical dates arising from the 2026 corporate law changes. Corporate lawyers in Oman should ensure clients have this timeline built into their compliance calendars immediately.

MOCIIP filings are submitted through the Ministry’s e‑services portal. Companies should register for portal access well in advance of the deadline to avoid last‑minute processing delays. The authorised manager is the default signatory for all MOCIIP compliance filings unless the board has passed a formal delegation resolution.

Penalties for non‑compliance include administrative fines, suspension of the company’s commercial licence and, in serious cases, referral to the Public Prosecution. The quantum of fines varies by offence and company grade, with the highest penalties reserved for Grade 1 companies that fail to file the annual compliance certificate or maintain the UBO register.

Corporate Governance and Practical Steps for Boards

The 2026 reforms require boards and general counsels to take immediate governance actions. The following checklist summarises recommended board‑level steps:

• Board resolution. Pass a resolution acknowledging the new regulatory requirements, delegating implementation to the authorised manager or company secretary, and setting internal deadlines that precede the statutory deadline.
• Governance audit. Conduct an internal review of existing governance documents, articles of association, delegation of authority matrices and signatory mandates, to ensure consistency with the new rules.
• Delegation clause. Where the authorised manager delegates signing authority, include clear scope limitations, a defined duration and revocation provisions.
• Record keeping. Ensure that board minutes record the adoption of compliance measures. A sample minute entry: “The Board noted the amendments to the Commercial Companies Regulation effective 11 January 2026 and resolved to direct the Authorised Manager to complete all compliance steps by no later than [internal deadline].”
• Training. Brief all directors and senior officers on the new UBO, authorised manager and top‑up tax obligations, and assign a compliance coordinator.

Enforcement Risk and Penalties

Enforcement authority is shared between MOCIIP (for commercial companies generally) and the FSA (for entities regulated under the Capital Market Law). Both regulators have been granted expanded powers under the 2026 amendments to inspect company records, demand production of the UBO register and impose sanctions for non‑compliance.

The typical enforcement escalation follows this pattern:

• Warning notice. An initial written notice requiring the company to rectify the breach within a specified period.
• Administrative fine. Imposed if the breach is not rectified within the notice period. Fines increase with the severity and duration of non‑compliance.
• Licence suspension. For persistent or serious breaches, MOCIIP may suspend the company’s commercial licence, effectively halting trading.
• Criminal referral. In cases involving fraud, wilful concealment of beneficial ownership or obstruction of a regulatory investigation, the matter may be referred to the Public Prosecution.

Companies that discover a compliance gap after the deadline should take immediate remedial action and self‑report to MOCIIP. Industry observers expect that prompt voluntary disclosure will be treated as a mitigating factor in penalty assessments.

Practical Resources and Templates

To assist compliance teams, the following templates and resources are available for download. Each template follows the format prescribed by the Commercial Companies Regulation and MOCIIP guidance:

• UBO Declaration Template. A ready‑to‑use beneficial ownership declaration form, including fields for all prescribed personal data and a signature block for the authorised manager.
• Annual Compliance Certificate. A model certificate for Grade 1 and Grade 2 companies, with tick‑box confirmations mapped to each applicable provision of the Regulation.
• Sample Board Resolution. A resolution template authorising the authorised manager to complete all MOCIIP filings and establish the UBO register.
• MOCIIP Filing Checklist. A step‑by‑step checklist covering portal registration, document preparation, filing submission and confirmation tracking.
