The United Arab Emirates has introduced a Domestic Minimum Top-up Tax framework that affects certain multinational enterprise groups operating in the country. In October 2026, the Federal Tax Authority issued a new guide explaining the scope of the regime and the registration obligations of entities covered by the legislation. For businesses that are part of large multinational groups, understanding the revenue threshold, group structure and registration requirements is important for determining whether the UAE Top-Up Tax rules apply. This guide explains the key concepts, the applicable revenue threshold and the practical steps businesses should consider when reviewing their tax obligations.

What Is the UAE Top-Up Tax?

The UAE Domestic Minimum Top-up Tax (DMTT) is a tax framework designed to ensure that qualifying multinational enterprise groups are subject to a minimum level of taxation on relevant profits within the UAE. The regime forms part of the UAE’s corporate taxation framework and applies to qualifying Constituent Entities that belong to multinational enterprise groups meeting the prescribed global revenue threshold. The UAE Domestic Minimum Top-up Tax applies to financial years starting on or after 1 January 2025. It is important to distinguish this regime from the general UAE Corporate Tax rules. The Domestic Minimum Top-up Tax has its own scope conditions and requirements, and it does not automatically apply to every company registered in the UAE.

What Is the Revenue Threshold for UAE Top-Up Tax?

The UAE Domestic Minimum Top-up Tax generally applies to Constituent Entities that are members of multinational enterprise groups with consolidated annual global revenue of at least: €750 million The threshold must be met in at least two of the four financial years immediately preceding the financial year in which the UAE Domestic Minimum Top-up Tax applies. The assessment is based on the multinational enterprise group’s consolidated financial statements, rather than solely on the revenue of an individual UAE company.

Why Does the Threshold Matter?

A UAE entity may have relatively modest local revenue but still need to assess whether it falls within the regime because it belongs to a multinational group that meets the global revenue threshold. Businesses should therefore consider their wider group structure and consolidated financial information before concluding that the regime does not apply.

Who Is Affected by the UAE Domestic Minimum Top-up Tax?

The regime is relevant to Constituent Entities that form part of multinational enterprise groups meeting the prescribed revenue conditions, subject to the applicable legislation and exclusions. Depending on the group structure, the relevant entities may include UAE-based companies and other entities that fall within the legislative definition of a Constituent Entity. Not every entity within a large group necessarily has the same tax treatment. Specific exclusions and special rules may apply to certain entities, and businesses must assess their circumstances against the legislation.

What Is the Federal Tax Authority’s New Top-Up Tax Guide?

On 7 October 2026, the Federal Tax Authority announced the issuance of a new Top-up Tax Guide on Scope and Registration. The guide provides information to help multinational enterprise groups determine whether they fall within the scope of the UAE Domestic Minimum Top-up Tax legislation and understand their registration obligations. According to the Federal Tax Authority, the guide covers:
  • The conditions for determining whether a multinational enterprise group falls within the scope of the regime.
  • The types of entities that are subject to Top-Up Tax.
  • Entities that may fall outside the scope under the applicable rules.
  • The registration process for entities subject to the legislation.
  • The applicable registration timelines.
Businesses should review the guide alongside the relevant legislation to establish which requirements apply to their particular group structure.

How Should Businesses Determine Whether They Are in Scope?

Determining whether the UAE Top-Up Tax applies requires more than reviewing a company’s standalone financial statements. Businesses should consider the following areas when carrying out an initial assessment.

1. Review the Multinational Group Structure

Identify the entities within the group and determine which entities may qualify as Constituent Entities under the applicable legislation. This assessment should consider the group’s ownership structure and the relevant legal and accounting classifications.

2. Review Consolidated Global Revenue

Check the group’s consolidated revenue for the relevant financial years. The €750 million threshold must be assessed using the prescribed four-year lookback period, with the threshold required to be met in at least two of those years.

3. Identify Potentially Excluded Entities

The legislation contains specific rules concerning entities that may be excluded from the regime. Businesses should assess any potentially applicable exclusions carefully instead of assuming that every entity in a qualifying group is treated identically.

4. Determine Registration Obligations

Once the scope assessment has been completed, the relevant entities should determine whether they are required to register and identify the applicable registration deadlines. The Federal Tax Authority’s official Scope and Registration Guide should be consulted for the detailed requirements and timelines.

How Is Top-Up Tax Different from Standard UAE Corporate Tax?

Although both regimes relate to business taxation, the UAE Domestic Minimum Top-up Tax and the general Corporate Tax framework have different scope conditions and compliance considerations.
Area General UAE Corporate Tax Domestic Minimum Top-up Tax
Scope Determined under the applicable Corporate Tax legislation Generally linked to qualifying multinational enterprise groups and the specific DMTT rules
Revenue assessment Depends on the applicable Corporate Tax provisions Includes a consolidated global revenue threshold of at least €750 million in at least two of the four preceding financial years
Effective period Depends on the relevant Corporate Tax rules Financial years starting on or after 1 January 2025
Compliance assessment Based on the requirements applicable to the taxpayer Requires a separate assessment of group scope, entity status and applicable obligations
The two regimes should not be treated as interchangeable. Businesses must assess their obligations under each applicable set of rules.
