UAE Pillar Two: Clarifying Information Return Filing for MNEs

Introduction

The UAE Ministry of Finance has issued Ministerial Decision No. 133 of 2026, providing crucial clarity on which entities within multinational enterprise (MNE) groups operating in the UAE are responsible for filing the Pillar Two Information Return with the Federal Tax Authority (FTA). This decision, effective for fiscal years beginning on or after January 1, 2025, precisely designates the specific UAE entity tasked with this critical reporting obligation under the Domestic Minimum Top-up Tax (DMTT) framework.

This advisory note outlines the implications of this new guidance for MNEs in the UAE. It details the scope of Pillar Two and the DMTT, identifies the responsible filing entities, clarifies the effective dates, and provides actionable steps for businesses to ensure timely and accurate compliance with the UAE's evolving international tax standards. Understanding these requirements is essential for MNEs to mitigate risks and streamline their tax compliance processes.

Understanding Pillar Two and the UAE's Domestic Minimum Top-up Tax

Pillar Two is a global tax framework developed by the Organisation for Economic Co-operation and Development (OECD) to ensure that large MNEs pay a minimum effective tax rate of 15% on their profits, regardless of where those profits are generated. This initiative aims to address base erosion and profit shifting by establishing a global anti-base erosion (GloBE) rule. The UAE, in its commitment to international tax standards and transparency, has adopted this framework.

The Domestic Minimum Top-up Tax (DMTT) is a key mechanism within the UAE's implementation of Pillar Two. It allows the UAE to collect the 'top-up' tax that would otherwise be collected by other jurisdictions under the Income Inclusion Rule (IIR) or Undertaxed Profits Rule (UTPR) of the GloBE rules. By implementing the DMTT, the UAE ensures that any profits of in-scope MNEs generated within its borders, if taxed below the 15% minimum rate, are subject to a domestic top-up tax. This approach ensures the UAE retains taxing rights over these profits, reinforcing its fiscal sovereignty while adhering to global tax norms.

Ministerial Decision No. 133 of 2026: The Core Clarification

Issued on August 26, 2026, Ministerial Decision No. 133 of 2026 directly addresses a fundamental compliance question for MNEs: who is explicitly responsible for filing the Pillar Two Information Return locally in the UAE? Before this decision, MNEs understood the broad obligations, but the specific entity within a complex corporate structure tasked with local reporting lacked explicit clarity. This new guidance eliminates that ambiguity.

The decision establishes clear lines of responsibility, thereby helping MNEs to:

• Enhance Compliance Certainty: Businesses now have a definitive understanding of which legal entity is accountable for submitting the required information.
• Streamline Internal Processes: With defined responsibilities, MNEs can better allocate resources, develop appropriate data collection systems, and prepare their teams.
• Mitigate Non-Compliance Risks: Clear guidance reduces the likelihood of missteps and potential penalties associated with incorrect or delayed filings.

This clarity is crucial as MNEs prepare for the significant data gathering and reporting requirements imposed by Pillar Two.

Who Must File the Pillar Two Information Return in the UAE?

Ministerial Decision No. 133 of 2026 specifies that, generally, a Constituent Entity of an MNE group located in the UAE will be responsible for filing the Pillar Two Information Return. This rule ensures that the obligation for local reporting rests with an entity that is an integral part of the MNE group's consolidated financial statements in the UAE.

Defining a Constituent Entity

For Pillar Two purposes, a Constituent Entity refers to any separate legal entity or permanent establishment of an MNE group that is included in the consolidated financial statements of the Ultimate Parent Entity (UPE) or would be included if equity interests were consolidated. Identifying the correct Constituent Entity within a complex group structure is the first critical step for compliance.

Scenarios for Filing Responsibility

While the general rule points to a UAE-based Constituent Entity, the decision outlines specific conditions and scenarios that determine which particular Constituent Entity holds this responsibility. These typically align with the broader OECD GloBE rules, which often look to:

• Ultimate Parent Entity (UPE) in the UAE: If the MNE group's UPE is located in the UAE, it would generally be responsible for filing the Pillar Two Information Return for the entire group's operations in the UAE, and potentially for other jurisdictions where no local filing obligation exists.
• Designated Filing Entity in the UAE: An MNE group might designate a specific Constituent Entity in the UAE to undertake the filing obligation on behalf of all UAE Constituent Entities. This streamlines reporting, provided the designation meets the criteria set out in the decision.
• Local Constituent Entity: In other cases, where neither the UPE nor a designated entity files, a local Constituent Entity may be required to file specific information pertaining to its operations.

MNE groups must meticulously review their organizational structures and the specific conditions in Ministerial Decision No. 133 of 2026 to identify their precise filing obligations.

When Do These Filing Requirements Take Effect?

These updated filing requirements, clarified by Ministerial Decision No. 133 of 2026, are applicable for fiscal years starting on or after January 1, 2025.

This means that MNEs operating in the UAE need to integrate these new obligations into their tax and financial planning well in advance of their first reporting period. For many entities, the first Pillar Two Information Return will be due in mid-2026 or later, depending on their fiscal year end.

Why This Clarification is Critical for UAE Businesses

Ministerial Decision No. 133 of 2026 holds significant importance for MNEs with operations in the UAE for several reasons:

• Compliance Certainty: The decision eliminates prior ambiguities regarding the filing entity. This clear directive allows MNEs to confidently assign responsibility and develop robust compliance frameworks, reducing the risk of unintended non-compliance.
• Risk Mitigation: Understanding who must file directly translates into better risk management. MNEs can now accurately identify potential areas of exposure to penalties for non-compliance, which can be substantial under Pillar Two rules. Proper designation helps prevent missed deadlines or inaccurate submissions.
• Strategic Planning: Clarity on filing responsibilities enables MNEs to incorporate these specific obligations into their broader tax strategy and operational planning. This allows for a more proactive approach to Pillar Two compliance, rather than a reactive scramble.
• Data Management and Systems Development: Identifying the filing entity early facilitates the establishment of appropriate data collection and reporting mechanisms. Pillar Two requires extensive granular financial and tax data. Knowing the responsible entity ensures that necessary systems are developed or adapted to gather, aggregate, and report this data accurately, from calculating GloBE Income and Adjusted Covered Taxes to preparing the full GloBE Information Return.
• Efficient Resource Allocation: With designated responsibilities, finance and tax teams can allocate their human and technological resources more efficiently. This includes training personnel, investing in specialized software, and streamlining inter-company data flows.

This guidance underscores the UAE's commitment to implementing international tax standards in a structured and clear manner, providing MNEs with the necessary framework for successful navigation.

Navigating the GloBE Information Return (GIR) and its UAE Specifics

The Pillar Two Information Return, often referred to as the GloBE Information Return (GIR), is a comprehensive document that MNEs must submit to report their GloBE calculations. The GIR requires detailed information on an MNE group's effective tax rate, top-up tax calculations, and allocation across various jurisdictions. While the GIR is a global standard, Ministerial Decision No. 133 of 2026 specifies how its filing obligation is localized within the UAE.

The decision ensures that there is a clearly identifiable entity within the UAE responsible for the local submission of this critical data. This local filing requirement often complements, rather than replaces, the ultimate parent entity's broader GIR obligations. For MNEs, it means ensuring that their global reporting strategy smoothly integrates with their specific UAE compliance duties.

Key Actionable Steps for UAE MNEs

To ensure full compliance with the updated Pillar Two information return filing requirements, MNEs in the UAE should take the following immediate steps:

1. Identify Responsible Constituent Entities

• Review Group Structure: Conduct a thorough review of your MNE group's legal and operational structure within the UAE to precisely identify all Constituent Entities.
• Determine Filing Entity: Based on the criteria outlined in Ministerial Decision No. 133 of 2026, identify which specific Constituent Entity (or entities) will bear the primary responsibility for filing the Pillar Two Information Return. Consider scenarios involving a UAE-based UPE, a designated local filing entity, or other local entities.

2. Assess Data Preparedness and Gaps

• Map Data Requirements: Understand the specific financial and tax data points required for Pillar Two calculations. This includes data for GloBE Income, Adjusted Covered Taxes, substance-based income exclusion, and other relevant metrics.
• Evaluate Current Systems: Assess your existing enterprise resource planning (ERP) systems, financial reporting tools, and tax compliance software to determine their capability to capture, process, and aggregate the necessary data.
• Identify Gaps: Pinpoint any data gaps or system limitations that could hinder accurate Pillar Two calculations and reporting. Develop a clear plan to address these, which may involve system upgrades, new software implementation, or manual data collection processes.

3. Allocate Resources and Expertise

• Team Training: Ensure your finance, tax, and IT teams are fully aware of the new responsibilities and possess the requisite knowledge and training to meet them. Pillar Two demands specialized expertise.
• Expert Engagement: Consider the need for engaging external tax advisory experts who specialize in Pillar Two implementation. Their tailored insights can be invaluable in designing a robust compliance strategy and navigating specific local nuances.
• Budget Allocation: Allocate sufficient financial resources for system enhancements, training, and potential external consultancy.

4. Confirm Fiscal Year Alignment

• Verify Start Dates: Reconfirm the start date of your MNE group's fiscal year to determine the precise commencement of these new filing obligations. This is critical for establishing internal deadlines and planning.
• Transitional Rules: Remain aware of any transitional safe harbors or simplified reporting options that may be available, as detailed by the OECD and adopted by the UAE.

The Broader Context of UAE's Tax Framework

The UAE's continuous efforts to refine its Pillar Two implementation, including this specific clarification on filing responsibilities, underscore its commitment to maintaining a transparent, internationally compliant, and attractive tax environment. This aligns with broader initiatives such as the introduction of Corporate Tax and the implementation of Economic Substance Regulations (ESR). For MNEs, navigating this evolving landscape requires a holistic approach to tax compliance that integrates global standards with local specificities.

Understanding the interplay between these different tax regimes is paramount. While Pillar Two focuses on minimum effective taxation for large MNEs, Corporate Tax applies more broadly, and ESR ensures real economic activity supports reported profits. These interlocking regulations mean that a siloed approach to tax compliance is no longer viable. Businesses need a unified strategy that accounts for all obligations.

Preparing for Ongoing Compliance

Pillar Two is not a one-time compliance exercise but an ongoing obligation requiring continuous monitoring, data reconciliation, and periodic reporting. The initial filing of the Pillar Two Information Return for fiscal years starting on or after January 1, 2025, marks the beginning of this journey. MNEs must embed Pillar Two compliance into their annual tax cycles, ensuring that processes are repeatable, scalable, and adaptable to any future regulatory refinements.

This ongoing nature demands sustained investment in expertise, technology, and internal controls. Proactive engagement with regulatory updates, such as those published by the OECD and the UAE Ministry of Finance, will be essential for maintaining compliance and adapting to any future changes to the GloBE rules.

Conclusion

Ministerial Decision No. 133 of 2026 offers indispensable clarity for multinational enterprises operating in the UAE, precisely defining which entity holds the responsibility for submitting the Pillar Two Information Return. This targeted guidance removes much of the ambiguity previously surrounding local filing obligations under the Domestic Minimum Top-up Tax framework, allowing businesses to establish clear lines of accountability.

As MNEs prepare for these requirements, effective from fiscal years beginning on or after January 1, 2025, a proactive and detailed approach is critical. This involves identifying the specific Constituent Entity responsible for filing, assessing and enhancing internal data management systems, allocating appropriate resources, and ensuring the tax team possesses the necessary expertise.

Navigating the complexities of Pillar Two and its local implementation requires specialized knowledge and meticulous planning.
