UAE Top - Up Tax: What MNEs Need to Know
On 16 July 2026, the Federal Tax Authority (FTA) issued Decision No. 12 of 2026, introducing further clarity on the administrative requirements applicable to entities falling within the UAE Top-Up Tax regime.
The Decision addresses registration, deregistration, and notifications relating to changes in an entity's scope status. It applies to Fiscal Years starting on or after 1 January 2025.
For businesses that are part of an MNE Group, this development makes it important to understand not only whether the Top-Up Tax framework applies, but also what compliance responsibilities may arise once an entity falls within its scope.
What Is the UAE Top-Up Tax?
The UAE Top-Up Tax forms part of the broader international tax framework applicable to qualifying Multinational Enterprise Groups. At a high level, it is intended to ensure that qualifying multinational groups are subject to an appropriate minimum level of taxation on their profits across jurisdictions.
The UAE introduced its Top-Up Tax framework through Cabinet Decision No. 142 of 2024, which establishes the underlying provisions for the imposition of Top-Up Tax on qualifying multinational enterprises.
The regime does not apply to every company operating in the UAE. Its application depends on whether the relevant MNE Group and its entities meet the conditions prescribed under the applicable legislation. The first step for any potentially affected business is to determine whether the group falls within scope.
What Does FTA Decision No. 12 of 2026 Change?
FTA Decision No. 12 of 2026 focuses primarily on the administrative and compliance requirements associated with Top-Up Tax. It provides a framework for entities to manage their status with the FTA, including requirements relating to:
- Registration for Top-Up Tax
- Deregistration from Top-Up Tax
- Notification where an entity is out of scope
- Notification where an entity becomes in scope again
- Filing arrangements involving a Domestic Designated Filing Entity
This provides greater clarity for businesses on how their Top-Up Tax status should be communicated and maintained with the FTA.
How Does Top-Up Tax Registration Work?
For an entity that falls within the scope of the Top-Up Tax provisions, registration with the FTA becomes an important compliance requirement.
The Decision links the registration requirement to the first Fiscal Year in which the entity is within scope and establishes the applicable period for submitting the Tax Registration application. It also includes transitional provisions for certain entities covered by the earlier Fiscal Years to which the framework applies.
This means businesses should not look only at their current tax position. They should also identify the relevant Fiscal Year and determine when their registration obligation arises.
What Happens When an Entity Is No Longer in Scope?
A change in status does not necessarily mean that an entity's compliance obligations end immediately. Where an entity ceases to be within scope, the Decision provides mechanisms for dealing with that change, including out-of-scope notifications and, where appropriate, Tax Deregistration.
These are separate compliance processes and should not be treated as interchangeable.
| Process | When It Applies |
| Out-of-scope notification | The entity's MNE Group ceases to be within scope for the applicable Fiscal Year, subject to the conditions and validity provisions set out in the Decision. |
| Tax Deregistration | The entity meets the relevant conditions for ending its Top-Up Tax registration, which is a separate and further compliance step. |
Is Deregistration Automatic Once an Entity Is Out of Scope?
No. One of the important practical points in the Decision is that an entity becoming out of scope does not automatically result in deregistration.
The Decision sets out specific requirements that must be satisfied before deregistration can be approved, including:
- Settling outstanding Top-Up Tax and penalties
- Completing the relevant Top-Up Tax and Pillar Two Information Return filing obligations
This means entities leaving an MNE Group, ceasing operations, or otherwise becoming out of scope should review their outstanding compliance position before assuming their Top-Up Tax obligations have ended.
The Decision also gives the FTA the ability, in certain circumstances, to deregister an entity based on information available to it, even where the entity has not submitted a deregistration application.
Can an Entity Become In-Scope Again After Being Out of Scope?
Yes. An entity previously treated as out of scope may subsequently become subject to the Top-Up Tax provisions again. The Decision provides for an in-scope notification in this situation.
This is particularly relevant for MNE Groups whose structure or circumstances change over time. An entity should not assume that an earlier out-of-scope position will remain valid indefinitely. Businesses should periodically review their group structure and Top-Up Tax status to identify whether circumstances have changed.
What Is a Domestic Designated Filing Entity?
The Decision also recognises situations where a Domestic Designated Filing Entity is appointed within certain domestic group structures. Where applicable, the Domestic Designated Filing Entity may submit relevant registration, deregistration and scope notifications on behalf of other members of the relevant domestic group structure.
For groups with multiple UAE entities, understanding whether such an arrangement applies, and clearly defining the respective responsibilities of the entities involved, is an important part of managing Top-Up Tax compliance.
What Should Businesses Be Doing Now?
Businesses that may fall within the scope of the UAE Top-Up Tax regime should take a structured approach to their compliance review.
- Determine whether the group is within scope. Assess the MNE Group against the relevant scope requirements under the UAE Top-Up Tax framework.
- Identify the relevant Fiscal Year. Several of the administrative requirements under the Decision are linked to the entity's Fiscal Year.
- Review the entity's current status. Establish whether the entity is required to register, has already registered, is out of scope, or may need to submit a notification or deregistration application.
- Monitor changes in group structure. Changes in ownership, group composition or other circumstances may affect Top-Up Tax status, so periodic review is important.
- Review filing responsibilities. Where a Domestic Designated Filing Entity is involved, establish which obligations are managed centrally and which remain applicable to individual entities.
Conclusion
FTA Decision No. 12 of 2026 provides further clarity on the administrative framework surrounding UAE Top-Up Tax. For qualifying MNE Groups, compliance is not limited to determining whether Top-Up Tax applies. Entities must also consider their registration status, notification obligations, deregistration requirements and ongoing responsibilities when circumstances change.
As the Decision applies to Fiscal Years starting on or after 1 January 2025, businesses that may fall within the scope of the UAE Top-Up Tax regime should review their position now and assess whether any action is required.
