UAE entities within large multinational groups should review their position now particularly where 30 November 2026 may be the registration deadline.
Quick Take
A UAE company does not need to be a large business in its own right to fall within the UAE Top-up Tax framework.
A relatively small UAE subsidiary may still be relevant if it forms part of a multinational group with consolidated annual revenue of €750 million or more in at least two of the four Fiscal Years immediately preceding the relevant Fiscal Year.
The Federal Tax Authority’s August 2026 publication, TTGREG1 – Top-up Tax: Scope and Registration, provides important practical guidance on which UAE entities may be within scope, who needs to register and when registration must take place.
For some groups, the key date is:
30 November 2026
For UAE subsidiaries, regional headquarters, holding structures and family-owned international groups, this is an important moment to look beyond the size of the local UAE entity and understand the wider group structure.
What Has Changed?
The UAE Top-up Tax itself is not new.
The framework was introduced through Cabinet Decision No. 142 of 2024, issued on 31 December 2024 and effective from 1 January 2025 for Fiscal Years beginning on or after that date.
The more recent development is the FTA’s detailed guidance on how the scope and registration requirements operate in practice.
The timeline can therefore be understood as follows:
31 December 2024
UAE Top-up Tax legislation issued.
1 January 2025
The rules begin applying to relevant Fiscal Years.
2026
Further registration and Pillar Two reporting requirements introduced.
August 2026
The FTA publishes detailed guidance on scope and registration.
For affected businesses, the focus is now shifting from understanding the legislation to ensuring that the correct UAE entities are identified and registered within the applicable deadline.
What Is UAE Top-up Tax?
The UAE Top-up Tax forms part of the international OECD Pillar Two framework, which is designed for very large multinational enterprise groups.
The UAE legislation applies a 15% Minimum Rate.
Importantly, this should not be interpreted as simply adding 6% to the UAE’s standard 9% Corporate Tax rate.
Pillar Two operates under a separate set of rules for calculating income, covered taxes, exclusions, adjustments and the relevant Effective Tax Rate.
For many UAE businesses, however, the immediate question is not how much Top-up Tax might ultimately be payable.
It is whether the business is part of a group that falls within the regime at all.
The €750 Million Test
The starting point is the multinational group’s consolidated annual revenue.
The rules apply to relevant Constituent Entities of an MNE Group where consolidated annual group revenue reaches:
€750 million or more in at least two of the four Fiscal Years immediately preceding the tested Fiscal Year.
The group must also be multinational.
Broadly, an MNE Group needs at least one entity or Permanent Establishment located in a jurisdiction different from that of its Ultimate Parent Entity.
This creates an important distinction for UAE businesses.
The relevant question is not simply:
“How much revenue does our UAE company generate?”
It is:
“How large is the multinational group to which our UAE company belongs?”
Why a Small UAE Subsidiary May Still Matter
Consider a UAE company generating annual local revenue of only AED 20 million.
On its own, it may not appear to be the type of business associated with global minimum tax rules.
But assume it belongs to an international group with the following consolidated revenues:
| Fiscal Year | Consolidated Group Revenue |
|---|---|
| 2021 | €720 million |
| 2022 | €790 million |
| 2023 | €730 million |
| 2024 | €820 million |
For FY 2025, the group exceeded the €750 million threshold in two of the previous four Fiscal Years: 2022 and 2024.
Assuming the other relevant conditions are satisfied, the group meets the revenue threshold.
The UAE subsidiary’s own AED 20 million turnover does not change that conclusion.
The threshold is tested at group level, not simply at the level of the individual UAE company.
This is particularly relevant for UAE subsidiaries of major international businesses whose local operations may be relatively modest compared with the size of the global organization.
What About Large UAE-Only Groups?
Size alone does not determine whether the rules apply.
Consider a UAE group generating €1 billion of annual revenue, but with every company and Permanent Establishment located solely in the UAE.
Despite its size, it remains a purely domestic UAE group.
The FTA guidance confirms that purely domestic UAE groups do not fall within the QDMTT scope simply because they exceed the €750 million revenue threshold.
The practical test is therefore closer to:
Large Multinational Group + €750 Million Threshold = Review Required
Which UAE Entities May Be Relevant?
The underlying Cabinet Decision brings relevant Constituent Entities located in the UAE within the Top-up Tax framework.
The regime can also extend to:
- Joint Ventures and JV Subsidiaries located in the UAE;
- certain UAE-created Stateless Constituent Entities that are Reverse Hybrid Entities; and
- other relevant UAE members of an in-scope multinational group.
A qualifying group may appoint a Domestic Designated Filing Entity (DDFE) to handle certain obligations on behalf of relevant UAE entities.
One point is particularly important:
Top-up Tax registration is separate from ordinary UAE Corporate Tax registration.
A company that is already registered for UAE Corporate Tax should therefore not assume that its existing registration automatically satisfies its Top-up Tax obligations.
Are Any Entities Excluded?
Yes.
Not every entity connected to a large multinational group is automatically subject to Top-up Tax.
The legislation identifies a number of Excluded Entities, including certain:
- Governmental Entities;
- International Organizations;
- Non-profit Organizations;
- Pension Funds;
- Investment Funds that are Ultimate Parent Entities; and
- Real Estate Investment Vehicles that are Ultimate Parent Entities.
Certain qualifying entities owned by excluded entities may also benefit from an exclusion.
An Investment Entity located in the UAE is also not subject to Top-up Tax, subject to the detailed legislative definition.
The FTA guidance confirms that an entity which is not subject to the Top-up Tax charging provisions is generally not required to register.
The classification of each UAE entity therefore matters.
Zero Tax Does Not Necessarily Mean Zero Compliance
One of the more important practical distinctions in the FTA guidance concerns entities whose calculated Top-up Tax may ultimately be zero.
It can be tempting to assume:
“If there is no Top-up Tax to pay, there is nothing to register.”
That is not necessarily the case.
For example, subject to the applicable conditions and election, the de minimis exclusion can result in zero Top-up Tax where average UAE Pillar Two Revenue is below €10 million and average Pillar Two Income or Loss is a loss or below €1 million.
However, an in-scope entity may still have a registration obligation even where its Top-up Tax is deemed to be zero.
Tax liability and registration responsibility should therefore be considered separately.
30 November 2026: The Registration Deadline to Check
For certain groups, this is the most immediate issue.
Where the relevant Fiscal Year ended before 30 April 2026, the entity or the DDFE acting on its behalf must submit the Top-up Tax registration application:
On or before 30 November 2026
For other cases, registration is generally required within seven months from the end of the first Fiscal Year in which the entity is within scope.
For example:
| First In-Scope Fiscal Year End | Registration Timing |
|---|---|
| 31 December 2025 | 30 November 2026 |
| 31 March 2026 | 30 November 2026 |
| 30 June 2026 | Generally 31 January 2027 |
For international groups with UAE entities, the practical priority should therefore be to establish the relevant Fiscal Year, identify the entities within scope and confirm the applicable registration deadline.
What Happens If Registration Is Late?
Missing the registration deadline can have a direct financial consequence.
A late Top-up Tax registration application may result in an:
AED 10,000 Administrative Penalty
Where a DDFE is responsible for multiple entities and fails to register them within the prescribed timeframe, the AED 10,000 penalty can apply in respect of each affected entity.
The FTA may also register an entity based on information available to it, with the registration taking effect from the date on which the entity was originally required to register.
For groups with several UAE entities, the potential exposure therefore deserves attention well before the deadline.
Registration Is Only the Beginning
Registration is one part of the wider Pillar Two compliance framework.
Once an entity is within scope, separate Top-up Tax Return obligations may also apply.
Under the Cabinet Decision, the return is generally due 15 months after the end of the Reporting Fiscal Year, extending to 18 months for the first Transition Year.
Any Top-up Tax payable is due in UAE Dirhams when the Top-up Tax Return becomes due.
Affected groups should therefore think beyond registration and consider whether their systems, group reporting processes and UAE entity information are ready for the wider compliance requirements.
What Should UAE Businesses Be Reviewing Now?
For DFO clients with international business interests, overseas parent companies, cross-border subsidiaries or multinational family structures, a practical review should begin with five questions:
- Is there a parent company, subsidiary or Permanent Establishment outside the UAE?
- Did consolidated group revenue reach €750 million or more in at least two of the previous four Fiscal Years?
- Which UAE entities sit within the relevant multinational group?
- Do any exclusions or special classifications apply to those entities?
- Could 30 November 2026 be the applicable registration deadline?
If the group is multinational and meets the revenue threshold, the UAE Top-up Tax position should be reviewed carefully rather than assessed solely by reference to the size or profitability of the UAE entity.
The DFO Perspective
For internationally active families, entrepreneurs and corporate groups, tax compliance increasingly depends on understanding the whole structure, not simply each company in isolation.
A UAE subsidiary may have limited turnover, a small local team and an ordinary Corporate Tax profile, while sitting within a global group large enough to bring it into an entirely different compliance framework.
That is why the FTA’s August 2026 guidance matters.
The key issue is not whether a UAE company looks large enough to be affected.
It is whether the global group behind it meets the relevant conditions.
With the first major registration deadline approaching, groups with UAE entities should establish their position early, identify the entities that may require registration and ensure that responsibility for the process is clearly allocated.
The questions to ask now are straightforward:
Is the group multinational?
Has consolidated revenue reached €750 million or more in at least two of the previous four Fiscal Years?
And if so, has the UAE registration position been reviewed ahead of 30 November 2026?
