The UAE has not increased its general Corporate Tax rate from 9% to 15%.
The 15% rate belongs to a separate international tax regime aimed at large multinational enterprise groups. Known in the UAE as the Domestic Minimum Top-up Tax, or DMTT, the regime forms part of the OECD’s Pillar Two global minimum tax framework and applies to qualifying multinational groups meeting the prescribed revenue threshold.
With Federal Tax Authority Decision No. 12 of 2026, the UAE has now introduced important procedural rules governing how entities within that regime must register, deregister and notify the Federal Tax Authority of changes to their scope status.
The Decision applies to Fiscal Years beginning on or after 1 January 2025.
For affected multinational groups, the development marks an important transition. The UAE’s minimum tax framework is no longer simply a question of determining whether additional tax may be payable. Businesses must now ensure that the entities within their group satisfy a separate set of registration and notification obligations within prescribed deadlines.
What Is the UAE’s 15% Minimum Tax?
The Domestic Minimum Top-up Tax is designed to ensure that qualifying multinational enterprise groups are subject to an effective tax rate of at least 15% on relevant profits in the UAE, calculated according to the specialised rules of the Pillar Two framework.
It does not replace the UAE Corporate Tax regime.
A UAE company may therefore remain subject to the ordinary Corporate Tax rules while also falling within the scope of the DMTT because it forms part of a sufficiently large multinational group.
The distinction is important.
The UAE’s standard Corporate Tax framework generally applies a 9% rate to taxable income exceeding the applicable threshold, subject to exemptions and special regimes.
The 15% minimum tax concerns a much narrower category of multinational groups and applies through a separate calculation designed specifically for the international minimum tax framework.
Businesses should therefore avoid treating 15% as a new general UAE Corporate Tax rate.
Which Multinational Groups Are Potentially Affected?
The UAE DMTT generally applies to constituent entities located in the UAE that form part of a multinational enterprise group meeting the Pillar Two revenue threshold.
Broadly, the group must have annual consolidated revenue of at least EUR 750 million in at least two of the four Fiscal Years immediately preceding the relevant Fiscal Year.
This means the regime is principally relevant to large international groups rather than ordinary UAE companies or smaller multinational businesses.
Potentially affected UAE entities may include:
- subsidiaries of international groups;
- regional holding companies;
- UAE operating companies;
- permanent establishments;
- intermediate holding structures;
- entities within internationally controlled investment structures; and
- other constituent entities forming part of an in-scope multinational group.
A UAE entity cannot determine its position simply by looking at its own annual turnover.
The test is fundamentally group-based.
A local company with relatively modest revenue may still be affected where its ultimate multinational group exceeds the consolidated revenue threshold.
What Does FTA Decision No. 12 of 2026 Change?
The underlying DMTT regime already determines which multinational groups may fall within the UAE minimum tax framework.
FTA Decision No. 12 of 2026 addresses a different question:
How and when must affected entities formally engage with the Federal Tax Authority?
The Decision establishes procedural requirements dealing with:
- Tax Registration;
- Tax Deregistration;
- notifications that an entity has become subject to the regime; and
- notifications that an entity falls outside its scope.
These requirements create their own compliance timetable.
An entity therefore needs to know not only whether the DMTT applies, but also when its registration or notification deadline begins.
The Seven-Month Registration Deadline
An entity that becomes subject to the Top-up Tax regime must generally complete its Tax Registration within seven months from the end of the first Fiscal Year in which it becomes in scope.
This makes identification of the first in-scope Fiscal Year critical.
A group that incorrectly concludes that the DMTT does not apply may not merely miscalculate its tax position. It may also miss the corresponding registration deadline.
Groups should therefore determine their scope position well before the seven-month period expires.
The analysis may require consideration of:
- consolidated group revenue;
- group ownership;
- entity classifications;
- acquisitions and disposals;
- restructurings;
- newly established entities;
- mergers;
- changes in the Ultimate Parent Entity; and
- whether any applicable exclusion operates.
Registration should therefore be treated as part of the group’s Pillar Two implementation project rather than as an isolated administrative filing.
Registration for DMTT Is Separate From Corporate Tax Registration
This distinction is particularly important.
A UAE company may already possess a Corporate Tax Registration Number and file ordinary Corporate Tax returns.
That does not necessarily mean every obligation associated with the Domestic Minimum Top-up Tax has automatically been satisfied.
The DMTT is a separate tax regime with its own:
- scope rules;
- calculations;
- filing requirements;
- registration procedures;
- notifications; and
- compliance timetable.
Tax teams should therefore avoid assuming that an existing UAE Corporate Tax registration completes the entity’s Pillar Two obligations.
Groups should specifically determine whether separate Top-up Tax registration is required under FTA Decision No. 12 of 2026.
What Is an In-Scope Notification?
An important feature of the Decision is the requirement to notify the FTA when an entity enters the scope of the Top-up Tax regime.
An in-scope notification must generally be submitted within seven months from the relevant date prescribed under the Decision.
This requirement is important because multinational groups can move into the regime for a variety of reasons.
For example:
- the group may cross the EUR 750 million revenue threshold;
- a UAE entity may be acquired by an in-scope multinational group;
- a new UAE constituent entity may be established;
- an existing ownership structure may change; or
- an entity that was previously excluded may cease to satisfy the relevant exclusion.
The group should therefore have a process for identifying changes in status as they occur.
Waiting until the annual tax return process may be too late.
What Is an Out-of-Scope Notification?
The Decision also recognises that an entity may cease to fall within the Top-up Tax regime.
An out-of-scope notification must generally be submitted within six months from the relevant event or date.
A change in scope may occur because of circumstances including:
- disposal of a UAE entity;
- restructuring of the multinational group;
- cessation of an entity;
- changes to group ownership;
- changes affecting the relevant revenue test; or
- another development altering the entity’s classification under the DMTT framework.
This creates an important compliance distinction.
An entity should not simply stop filing or assume that no further action is required because it believes it has fallen outside the regime.
The change itself may need to be formally communicated to the FTA.
Tax Deregistration Has Its Own Deadline
Where an entity becomes eligible or required to deregister for Top-up Tax purposes, the Decision generally requires the deregistration application to be submitted within six months from the relevant deregistration date.
Deregistration should not be confused with an out-of-scope notification.
Depending on the circumstances, a change in status may involve separate procedural requirements.
Groups should therefore determine:
- whether the entity has moved out of scope;
- whether notification is required;
- whether Tax Deregistration must also be completed; and
- when each deadline begins.
This is particularly relevant during mergers, liquidations, internal reorganisations and disposals.
Why Group-Level Coordination Is Essential
Pillar Two is fundamentally a multinational group compliance exercise.
A UAE subsidiary may not possess all the information required to determine whether it falls within the regime.
For example, the UAE finance team may need information from the Ultimate Parent Entity concerning:
- consolidated annual revenue;
- group financial statements;
- ownership changes;
- acquisitions;
- entity classifications;
- excluded entities;
- tax elections;
- group restructuring; and
- Pillar Two calculations performed elsewhere.
This means that compliance cannot be managed effectively by the UAE entity in isolation.
Groups should establish clear responsibility between:
- headquarters;
- regional tax teams;
- UAE finance personnel;
- legal teams;
- external tax advisers;
- accounting teams; and
- responsible filing entities.
Without that coordination, a UAE subsidiary may become subject to a registration requirement without receiving the necessary group information in time.
The EUR 750 Million Threshold Requires Careful Analysis
The revenue threshold may sound straightforward, but its application can involve complexity.
The analysis is based on the consolidated revenue of the multinational enterprise group rather than the revenue of an individual UAE company.
The relevant test generally considers whether the prescribed threshold was met in at least two of the four immediately preceding Fiscal Years.
Groups experiencing rapid growth, acquisitions or restructuring should therefore monitor the threshold continuously.
A business that was outside Pillar Two historically may enter scope as its consolidated revenue increases.
Similarly, acquisition by a larger multinational group may fundamentally change the UAE entity’s position even where nothing about its local business operations changes.
For this reason, M&A due diligence should increasingly include Pillar Two scope analysis.
The 15% Rate Is Based on an Effective Tax Rate Calculation
Another misconception is that an in-scope UAE company simply pays Corporate Tax at 15%.
The Pillar Two framework is more complex.
The regime broadly compares the relevant covered taxes of the UAE constituent entities with the income determined under the specialised Pillar Two rules to establish an effective tax rate.
Where that rate falls below the 15% minimum, a Top-up Tax may become payable, subject to the detailed calculation rules and available adjustments.
The process may involve matters including:
- adjusted financial accounting income;
- covered taxes;
- deferred tax adjustments;
- jurisdictional blending;
- substance-based exclusions;
- specific elections;
- safe harbours; and
- other Pillar Two adjustments.
The statutory 15% rate therefore cannot simply be applied to the ordinary taxable profit shown on the UAE Corporate Tax return.
Does the DMTT Affect Free Zone Companies?
Potentially, yes.
The existence of a UAE Free Zone entity within a large multinational group may require careful Pillar Two analysis.
A Free Zone company may qualify for the UAE’s 0% Corporate Tax rate on Qualifying Income where it satisfies the conditions applicable to a Qualifying Free Zone Person.
That domestic Corporate Tax treatment does not automatically remove the entity from the international minimum tax framework.
Where an in-scope multinational group has a low effective tax rate in the UAE under the Pillar Two calculation, the DMTT may potentially operate to bring the relevant effective tax level towards the 15% minimum.
This is precisely why multinational groups should not analyse Free Zone Corporate Tax and Pillar Two independently.
The interaction between them may materially affect the group’s overall UAE tax position.
Does the DMTT Affect Businesses Paying 9% Corporate Tax?
Potentially.
Paying the UAE’s ordinary 9% Corporate Tax rate does not automatically mean that a 6% Top-up Tax will be payable.
The Pillar Two effective tax rate is not calculated simply by subtracting 9% from 15%.
The relevant calculation uses its own income and covered-tax methodology, together with applicable exclusions, adjustments and elections.
Depending on the facts, the resulting effective rate could differ from the headline Corporate Tax rate.
This is why businesses should avoid simplistic calculations based only on the UAE statutory rate.
Why Registration Matters Even Where No Top-up Tax Is Expected
A multinational group may conclude that its UAE effective tax rate is at or above 15%, or that a safe harbour or another feature of the regime means no material Top-up Tax is ultimately payable.
That does not necessarily mean the entity can ignore registration and notification requirements.
Tax liability and tax compliance are separate questions.
An entity may still have obligations concerning:
- registration;
- notification;
- information reporting;
- filing; or
- supporting documentation
even where the final tax amount is nil.
The first step should therefore always be determining whether the entity is within scope.
Only then should the group determine the resulting payment position.
Changes in Group Structure Need Immediate Attention
Corporate transactions can alter Pillar Two status unexpectedly.
Relevant events may include:
- acquisitions;
- disposals;
- mergers;
- demergers;
- share transfers;
- establishment of new UAE subsidiaries;
- migration of entities;
- creation or closure of permanent establishments;
- changes to the Ultimate Parent Entity; and
- liquidations.
Tax and legal teams involved in corporate transactions should therefore include Top-up Tax registration consequences within transaction checklists.
The relevant question is no longer simply:
Will this acquisition affect our tax liability?
It may also be:
Does this transaction create a new UAE registration or notification deadline?
That procedural consequence can easily be overlooked during complex restructuring.
Multinationals Should Build a UAE Pillar Two Calendar
FTA Decision No. 12 of 2026 makes deadline management increasingly important.
Each potentially affected UAE entity should have a compliance calendar recording:
- the group Fiscal Year;
- the first Fiscal Year within scope;
- the registration deadline;
- notification deadlines;
- filing obligations;
- payment deadlines;
- restructuring events;
- deregistration dates; and
- responsibility for each filing.
The calendar should be integrated with the group’s global Pillar Two programme.
A global tax team may manage the overall calculation while the UAE entity remains responsible for local administrative requirements.
The two processes must therefore communicate effectively.
Data Readiness Is Just as Important as Registration
Registration is only one stage of DMTT compliance.
The broader Pillar Two regime requires extensive financial and tax information.
Groups may need to collect and reconcile:
- entity-level financial statements;
- consolidation data;
- tax expense information;
- deferred tax information;
- ownership records;
- payroll;
- tangible asset values;
- tax incentives;
- intercompany transactions; and
- information required for elections or safe harbours.
Many multinational groups were not historically required to maintain all of this information in the format demanded by Pillar Two.
Businesses should therefore use the registration stage as an opportunity to confirm whether their data systems are ready for the wider compliance burden.
Which Team Should Own the Process?
There is no single answer.
The most effective approach will depend on the group’s structure.
Responsibility may sit primarily with:
- group tax;
- UAE finance;
- regional tax;
- legal;
- corporate secretarial; or
- a dedicated Pillar Two project team.
However, no single function is likely to possess all necessary information.
Legal teams may know when an acquisition closes.
Finance teams may know the entity-level accounts.
Group tax may control the Pillar Two calculation.
Corporate secretarial teams may know when entities are incorporated or liquidated.
Compliance therefore requires information to move between departments.
Businesses should establish a clear internal trigger so that corporate events capable of changing DMTT status are communicated immediately to the team responsible for FTA filings.
Penalties Make Procedural Compliance Important
Tax regimes generally distinguish between the substantive obligation to pay tax and procedural obligations such as registration, filing, notification and record keeping.
Failure to satisfy procedural requirements can lead to administrative consequences even where the underlying tax amount is limited or ultimately nil.
Affected multinational groups should therefore treat the deadlines introduced by Decision No. 12 of 2026 as statutory compliance requirements rather than optional administrative guidance.
Where uncertainty exists regarding whether an entity is in scope, the issue should be assessed before the relevant deadline rather than after it has expired.
What Should Multinational Groups Do Now?
Groups with UAE operations should take several immediate steps.
Confirm whether the group meets the revenue threshold
The first step is identifying whether the multinational enterprise group falls within the Pillar Two size threshold.
Map every UAE constituent entity
The group should identify all UAE entities and permanent establishments potentially relevant to the DMTT calculation.
Determine each entity’s first in-scope Fiscal Year
This establishes when the registration timetable begins.
Review existing registrations
An ordinary Corporate Tax registration should not be assumed to satisfy Top-up Tax requirements.
Identify notification obligations
Entities moving into or out of scope should determine whether an in-scope or out-of-scope notification is required.
Review corporate changes since 1 January 2025
Acquisitions, disposals and restructurings may have altered the group’s UAE Pillar Two position.
Establish responsibility
Each entity should know who within the group is responsible for completing local FTA requirements.
Prepare the underlying data
Registration is only the beginning. The group should also ensure that the information needed for the broader DMTT calculation and reporting framework is available.
Why FTA Decision No. 12 of 2026 Matters
The Decision represents another stage in the implementation of the UAE’s international minimum tax framework.
The introduction of the DMTT established the substantive tax regime.
Decision No. 12 of 2026 now makes the administrative responsibilities more concrete.
For multinational groups, this shifts the compliance discussion from:
Does Pillar Two potentially apply to us?
towards:
Which UAE entities must register, what must they notify the FTA of, and when?
That is a significant operational change.
The UAE remains an attractive international business jurisdiction, but participation in the global economy increasingly requires compliance with international tax standards as well as domestic tax legislation.
Large multinational groups should therefore integrate DMTT compliance into their ordinary UAE tax governance rather than treating it as a one-off international tax project.
Conclusion
FTA Decision No. 12 of 2026 introduces an important new compliance layer for multinational groups subject to the UAE’s Domestic Minimum Top-up Tax.
The 15% minimum tax does not represent an increase in the UAE’s general Corporate Tax rate.
It applies through a separate Pillar Two framework targeted at large multinational enterprise groups meeting the prescribed consolidated revenue threshold.
Affected entities must now pay particular attention to registration, deregistration and scope notifications.
Tax Registration is generally required within seven months from the end of the first Fiscal Year in which an entity becomes subject to the regime, while deregistration and certain out-of-scope notifications generally operate on six-month timelines.
For multinational groups, the practical lesson is clear.
Pillar Two compliance in the UAE is no longer concerned only with calculating whether a Top-up Tax is payable. It now requires active monitoring of entity status, corporate changes and statutory deadlines across the group.
The 15% minimum rate may attract the headlines.
The immediate compliance challenge is knowing who must register and when.
