The UAE has formally aligned itself with the global tax reform agenda under Pillar Two of the OECD/G20 Inclusive Framework, introducing a Domestic Minimum Top-up Tax (DMTT) for large multinational enterprise (MNE) groups. This marks a significant shift in the international tax landscape for UAE-based entities that are part of global groups.

While the UAE remains a highly competitive and business-friendly jurisdiction, Pillar Two changes how low-tax outcomes are evaluated for large groups. The focus is no longer only on statutory tax rates or incentives, but on whether profits are ultimately taxed at a minimum effective rate of 15% on a jurisdictional basis.

This article provides a polished, detailed, and business-focused explanation of the UAE Global Minimum Tax regime, helping UAE businesses understand the scope, mechanics, implications, and next steps.

Understanding Pillar Two and the UAE’s Approach

Pillar Two (Global Minimum Tax) is designed to ensure that large MNE groups pay a minimum level of tax regardless of where they operate. If profits in a jurisdiction are taxed below the agreed minimum, a “top-up tax” applies to bridge the gap.

The UAE has chosen to implement a Domestic Minimum Top-up Tax (DMTT) through:

• Cabinet Decision No. 142 of 2024 on Top-up Tax on Multinational Enterprises, and
• Commentary and Agreed Administrative Guidance adopted for the purposes of the Cabinet Decision.

The UAE DMTT is intended to operate as a Qualified Domestic Minimum Top-up Tax (QDMTT), meaning it is designed to meet OECD qualification standards so that any top-up tax on UAE profits is collected locally rather than under foreign Income Inclusion Rules (IIR) or Undertaxed Profits Rules (UTPR).

By introducing a DMTT, the UAE ensures that taxing rights over UAE-based profits are preserved within the UAE tax system.

Effective date:
The UAE DMTT applies to financial years beginning on or after 1 January 2025.

Who Is Impacted? (Scope of Application)

Pillar Two in the UAE is highly targeted and does not apply to all businesses.

You are generally in scope if:

• You are a UAE entity that is part of a Multinational Enterprise Group, and
• The group has consolidated annual revenue of EUR 750 million or more
• In at least two of the four financial years preceding the relevant year.

Who is generally out of scope?

• Standalone UAE businesses
• UAE groups below the EUR 750 million threshold
• Many SMEs and mid-sized groups

In addition, certain “Excluded Entities” under the Pillar Two rules are outside the scope of the regime even if they belong to large groups. These typically include government entities, pension funds, certain investment funds, and non-profit organisations, subject to specific conditions.

Key takeaway:

Pillar Two is a large-group regime, not a universal corporate tax increase.

The 15% Minimum Rate and the Concept of “Top-up Tax”

Under the UAE DMTT:

• The minimum effective tax rate (ETR) is 15%, calculated at a jurisdictional (UAE) level.
• If the UAE ETR for a group is below 15%, a Top-up Tax may arise to bring the effective rate up to the minimum.

Importantly, this calculation is not based on UAE Corporate Tax rules alone. Instead, it follows the Pillar Two (GloBE) methodology, which relies heavily on financial accounting data, with prescribed adjustments.

How the UAE Top-up Tax Is Calculated (Simplified Overview)

While technically complex, the Pillar Two computation broadly follows these steps:

Step 1: Determine Pillar Two (GloBE) Income for the UAE

• Based on qualified financial statements of UAE constituent entities
• Adjusted for specific inclusions and exclusions under Pillar Two rules

GloBE income ≠ UAE taxable income

Step 2: Identify Adjusted Covered Taxes

Covered Taxes generally include:

• Current and deferred taxes on income or profits
• Taxes recorded in financial accounts, subject to detailed adjustment rules

Deferred tax treatment under Pillar Two is highly technical and constrained. The Commentary imposes conditions on recognition, recapture rules, and timing of reversals, meaning deferred taxes do not automatically reduce top-up tax exposure.

This step often creates the largest data and reconciliation challenge for groups.

Step 3: Compute the UAE Effective Tax Rate (ETR)

UAE ETR = Adjusted Covered Taxes ÷ Pillar Two (GloBE) Income ​​

If the ETR is below 15%, a Top-up Tax may apply.

Step 4: Apply Reductions, Exclusions & Safe Harbours

Before finalising any liability, several important relief mechanisms may reduce or eliminate the top-up tax.

Key Relief Mechanisms That Reduce Top-up Tax Exposure

A. Substance-Based Income Exclusion (SBIE)

Pillar Two recognises genuine economic substance. The SBIE reduces the amount of profit subject to top-up tax by reference to:

• Eligible payroll costs, and
• Eligible tangible assets

The UAE framework includes transitional relief rates from 2025 onward, which gradually phase down over time.

Practical impact:

Groups with real operations, people, and assets in the UAE often face lower top-up exposure than structures with minimal substance.

B. De Minimis Exclusion

Where UAE operations are relatively small (below defined income and profit thresholds), a de minimis exclusion may apply, resulting in no top-up tax for the year.

C. Elections

The rules allow certain annual elections (for example, in relation to the SBIE), which can materially affect outcomes depending on group circumstances.

Safe Harbours and Transitional Simplifications

To ease early adoption, the UAE Pillar Two framework incorporates simplification mechanisms, including:

• Simplified Calculations Safe Harbour, under which the UAE Top-up Tax may be deemed nil, subject to conditions
• Transitional rules for initial years (notably FY 2025 and FY 2026)

Safe harbours can significantly reduce compliance burden, but they are technical, elective, and documentation-heavy.

Impact on UAE Free Zones and Incentive Structures

Pillar Two does not automatically abolish UAE Free Zone incentives. However, for in-scope MNE groups:

• Low or zero-tax outcomes may still trigger top-up tax to reach 15%
• The net benefit of incentives must be assessed at a group level
• Substance and safe harbours play a critical role in determining final exposure

Free Zone incentives may continue to apply under UAE Corporate Tax, but they do not override the minimum taxation outcome required under Pillar Two for in-scope multinational groups.

Strategic shift:

Tax planning moves from “rate-based” to substance-based and data-driven decision-making.

Compliance, Data & Governance: The Real Challenge

For affected UAE businesses, Pillar Two is less about paying more tax and more about:

• Data availability and quality
• Alignment between finance, tax, and consolidation systems
• Tracking deferred tax positions and credits
• Maintaining audit-ready documentation

The adoption of OECD Commentary and Administrative Guidance reinforces that interpretation will be rigorous and internationally aligned.

What UAE Businesses Should Do Now

If your group may fall within scope, early preparation is critical.

Recommended action plan:

1. Confirm scope – assess the EUR 750m threshold and identify UAE constituent entities
2. Perform an impact assessment – estimate UAE ETR under Pillar Two rules
3. Assess safe harbour eligibility for 2025–2026
4. Build a Pillar Two data model linking financial reporting and tax provisioning
5. Establish governance & controls – roles, sign-offs, documentation
6. Prepare for compliance & reporting well ahead of deadlines

Frequently Asked Questions (FAQs)

1. Does Pillar Two apply to all UAE companies?

No. It generally applies only to UAE entities that are part of MNE groups with consolidated revenue of EUR 750 million or more.

2. When does the UAE Global Minimum Tax start?

For financial years beginning on or after 1 January 2025.

3. Is the minimum tax rate in the UAE now 15% for everyone?

No. The 15% minimum applies only under Pillar Two rules for in-scope MNE groups. UAE Corporate Tax rules remain separate.

4. Can UAE substance reduce Pillar Two exposure?

Yes. The Substance-Based Income Exclusion is one of the most important relief mechanisms.

5. Are Free Zone benefits still relevant?

Yes, but for large groups, benefits must be assessed after considering potential top-up tax.
