UAE’s 15% Minimum Tax for Multinationals: Scope and Exemptions Explained

DMTT Scope & Exemptions Explained

Following our last article introducing the UAE’s 15% Domestic Minimum Top-Up Tax (DMTT) for large multinational groups, this follow-up provides further information on which businesses fall within scope—and more importantly, which are exempt.

What Is the DMTT?
To recap briefly, the Domestic Minimum Top-Up Tax is part of the UAE’s alignment with the OECD’s Pillar Two framework, ensuring that multinational groups pay a minimum effective tax rate of 15% in each jurisdiction where they operate. Rather than replacing existing UAE corporate tax, the DMTT works alongside it—applying only in cases where the effective rate falls below the global threshold.

What Has Been Clarified? 

Exclusions for Smaller Entities 
The DMTT only applies to MNE groups with global revenue exceeding €750 million. Standalone companies and smaller business groups remain unaffected. 

No Retroactive Application 
The tax will only apply from the 2025 financial year onwards, and assessments will not cover previous periods. 

Treatment of Free Zone Income 
While income from qualifying free zone activities may continue to enjoy a 0% rate, any income outside the scope of free zone benefits could still be subject to the DMTT. 

Interaction With Existing UAE Corporate Tax 
The standard 9% corporate tax introduced in June 2023 will continue to apply. The DMTT is designed to work alongside, not replace, the existing tax framework. 

Implications for Business Planning 
  • Global Coordination: Multinational finance teams must now coordinate with UAE subsidiaries to ensure group-level compliance. 
  • Data Readiness: Companies need to gather and structure financial data across jurisdictions to meet reporting standards. 
  • Technology Upgrades: Tax reporting systems may need to be upgraded to handle the complexity of DMTT calculations and filings. 
Practical Steps for UAE Businesses in Scope

For large international groups operating in the UAE, the DMTT introduces a new layer of tax planning and compliance obligations. Here’s what to focus on in the months ahead:
  • Evaluate Group Revenue: Confirm whether your group exceeds the €750 million global threshold.
  • Map UAE Operations: Identify all UAE-based entities and review their tax profiles, Free Zone status, and qualifying activities.
  • Calculate Effective Tax Rate: Assess if your UAE operations will fall below the 15% threshold in 2025.
  • Prepare for Reporting: Begin updating systems and processes to meet upcoming reporting and compliance requirements aligned with the OECD's global standards.
Should You Be Concerned if You’re Not an MNE? 

For most UAE-based SMEs and family-owned firms, this tax will not apply.  

However, if you are advising large groups or anticipate future growth to that level, it is worth understanding the new rules.

Conclusion 

The additional guidance from the Ministry of Finance provides welcome clarity.  

While many UAE-based businesses are outside the scope, those within should use the remainder of 2024 to prepare.
