FTA confirms the registration timeline, with 30 November 2026 becoming a key deadline for many multinational groups

The UAE’s Top-up Tax regime has been in effect since 1 January 2025. Until recently, however, one important practical question remained:

If an entity falls within the scope of Top-up Tax, when does it need to register with the Federal Tax Authority?

That question has now been answered.

On 16 July 2026, the Federal Tax Authority issued FTA Decision No. 12 of 2026, setting out the registration, deregistration and related notification timelines under the UAE Top-up Tax regime.

For multinational groups with UAE operations, this brings the compliance timeline into much sharper focus.

For many affected entities, 30 November 2026 is now a key date to watch.

First, What Is UAE Top-up Tax?

The UAE Top-up Tax framework was introduced through Cabinet Decision No. 142 of 2024, issued on 31 December 2024 and applicable to fiscal years beginning on or after 1 January 2025.

The regime is primarily relevant to large multinational enterprise groups, rather than ordinary standalone businesses.

A key threshold is EUR 750 million in consolidated group revenue in at least two of the four fiscal years immediately preceding the fiscal year being assessed.

This distinction matters.

A UAE company does not need to generate EUR 750 million in revenue itself to potentially fall within the regime. The threshold is assessed based on the consolidated revenue of the multinational group.

As a result, even a relatively small UAE subsidiary may potentially be within scope if it forms part of a sufficiently large international group.

Equally, being within scope does not automatically mean that Top-up Tax will ultimately be payable. The actual tax position depends on the detailed calculations and provisions under Cabinet Decision No. 142 of 2024.

What Changed in July 2026?

Cabinet Decision No. 142 already established that entities subject to Top-up Tax must register with the FTA.

What remained outstanding was the practical timeline for doing so.

FTA Decision No. 12 of 2026, issued on 16 July 2026, now provides that missing piece by prescribing the registration and deregistration timelines.

The General Rule: Seven Months

An entity subject to Top-up Tax must generally submit its registration application:

Within seven months from the end of the first fiscal year in which the entity falls within scope.

However, an important transitional rule applies to certain entities.

30 November 2026: A Key Transitional Deadline

Where an entity’s fiscal year ended before 30 April 2026, its Top-up Tax registration application must be submitted on or before 30 November 2026.

This is particularly relevant for entities with a 31 December 2025 year-end.

Under the general seven-month rule, a 31 December 2025 year-end might initially suggest a registration deadline of 31 July 2026.

That is not the applicable deadline in this case.

Because the fiscal year ended before 30 April 2026, the transitional provision applies, moving the registration deadline to:

30 November 2026

Understanding whether the general or transitional rule applies is therefore an important part of assessing an entity’s compliance position.

Why Registration Matters

Top-up Tax registration is more than an administrative formality.

It represents an entity’s formal entry into the FTA’s wider Top-up Tax compliance framework.

Cabinet Decision No. 142 of 2024 provides for obligations that may include Top-up Tax Returns, payment of Top-up Tax and Pillar Two Information Returns.

Registration should therefore be considered as one part of a broader Pillar Two compliance process.

For multinational groups, this means the conversation should extend beyond whether tax is ultimately payable. The group must also understand which UAE entities are within scope, what their respective obligations are and when those obligations arise.

Registration Is Not the Only Deadline to Consider

FTA Decision No. 12 of 2026 also addresses the position of entities that leave the Top-up Tax regime.

An entity generally has six months to apply for deregistration from the earlier of:

• the date on which it ceases to exist; or
• the end of the fiscal year in which it leaves the MNE Group and is no longer within scope.

For an entity that ceased to exist before 30 June 2026, a transitional deregistration deadline of 31 December 2026 applies.

Importantly, deregistration cannot be completed until the relevant Top-up Tax and penalties have been settled and the required Top-up Tax Returns and Pillar Two Information Returns have been filed.

This reinforces the importance of looking at Top-up Tax compliance as an ongoing process rather than a single registration exercise.

What Happens If the Deadline Is Missed?

Top-up Tax registration should not be treated as optional.

Cabinet Decision No. 142 of 2024 brings certain provisions of the UAE Corporate Tax Law into the Top-up Tax framework, including provisions relating to tax assessments and penalties.

Failure to comply with the applicable registration requirements may therefore result in administrative penalties and broader compliance exposure.

However, the Decisions referenced here do not specify a particular AED amount for failure to meet the Top-up Tax registration deadline. A specific late-registration penalty should therefore not be assumed based on these Decisions alone.

What Should Multinational Groups Check Now?

The immediate priority is to determine whether the UAE entity falls within scope.

The assessment should begin at group level, rather than by looking only at the turnover of the individual UAE entity.

Organizations should consider the following questions:

Is the UAE entity part of a multinational group?

Does the group meet the EUR 750 million consolidated revenue threshold?

Is the UAE entity a Constituent Entity and within the scope of the Top-up Tax regime?

What was the entity’s first fiscal year in scope?

Which registration timeline applies?

Does the transitional deadline apply?

For qualifying cases, 30 November 2026 may be the critical registration date.

This is why an early scope assessment matters. A UAE entity may appear relatively small when viewed independently but still carry Top-up Tax compliance obligations because of the size and structure of the wider international group.

The Bigger Picture

The July 2026 Decision does not introduce a new tax.

Instead, it completes an important practical part of a framework that was already established.

31 December 2024
Cabinet Decision No. 142 of 2024 issued

1 January 2025
UAE Top-up Tax regime becomes applicable

16 July 2026
FTA Decision No. 12 of 2026 issued

Registration and deregistration timelines prescribed

30 November 2026
Key transitional registration deadline for qualifying entities

The direction is now much clearer.

The Top-up Tax rules were already in place. The registration clock has now been set.

For multinational groups with UAE operations, the focus should move from simply understanding that the regime exists to answering three practical questions:

Are we in scope? Which UAE entities need to register? And by when?
