UAE Pillar Two Registration Is Now Live: Complete Guide to UAE Domestic Minimum Top-Up Tax

UAE Pillar Two Registration and Domestic Minimum Top-Up Tax Guide
UAE Pillar Two registration is now an important compliance consideration for qualifying multinational enterprise (MNE) groups operating in the UAE. The UAE Domestic Minimum Top-up Tax (DMTT) applies to constituent entities of multinational groups that meet the applicable global revenue threshold of €750 million or more in at least two of the four financial years immediately preceding the relevant financial year.
The UAE DMTT applies to financial years beginning on or after 1 January 2025 and is closely aligned with the OECD Global Anti-Base Erosion (GloBE) Rules, which form part of the international Pillar Two framework.
For multinational businesses with operations in the UAE, understanding whether the group is within scope, identifying the relevant UAE entities and preparing for registration, reporting and tax obligations should be a priority.
This guide explains UAE Pillar Two registration, the €750 million threshold, UAE DMTT, who needs to check their eligibility, how the rules work, key compliance considerations, common mistakes and frequently asked questions.

Key Takeaways: UAE Pillar Two

Before going into the technical details, here are the most important points businesses should know:

  • The UAE has implemented a Domestic Minimum Top-up Tax (DMTT) as part of the Pillar Two framework.
  • The UAE DMTT applies for financial years beginning on or after 1 January 2025.
  • The relevant MNE revenue threshold is €750 million or more.
  • The threshold must generally be met in at least two of the four financial years immediately preceding the relevant financial year.
  • The threshold is based on the consolidated global revenue of the MNE group, not simply the UAE entity’s revenue.
  • UAE constituent entities of qualifying MNE groups should assess their Pillar Two obligations.
  • Pillar Two does not automatically mean that every UAE entity will have a top-up tax liability.
  • The UAE DMTT is closely aligned with OECD GloBE Rules.
  • The UAE’s DMTT received OECD transitional qualified status and qualified for the OECD Pillar Two safe harbour in 2025.
  • Businesses should review the latest UAE legislation and administrative guidance before completing their compliance process.

What Is UAE Pillar Two?

UAE Pillar Two refers to the UAE’s implementation of the international global minimum tax framework through its Domestic Minimum Top-up Tax (DMTT)
Pillar Two was developed through the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) to establish a global minimum effective tax framework for large multinational groups.
The framework is designed around a 15% minimum effective tax rate for qualifying MNE groups.
The UAE has implemented a domestic minimum top-up tax that is closely aligned with the OECD’s GloBE Model Rules, Administrative Guidance and Commentary. The Ministry of Finance states that the UAE DMTT is intended to ensure that the UAE domestic tax base is protected while remaining aligned with international tax standards.
In simple terms, Pillar Two aims to ensure that large multinational groups are subject to an appropriate minimum level of taxation in the jurisdictions where they operate.

What Is UAE Domestic Minimum Top-up Tax (DMTT)?

The UAE Domestic Minimum Top-up Tax, commonly called UAE DMTT, is the UAE’s domestic implementation of the Pillar Two minimum tax framework.
The DMTT applies to qualifying constituent entities of MNE groups operating in the UAE where the group meets the applicable global revenue threshold.
The UAE DMTT became effective for financial years beginning on or after 1 January 2025.
The rules are based closely on the OECD GloBE framework but also contain UAE-specific provisions.
This distinction is important because businesses should not rely solely on a general international Pillar Two explanation when determining their UAE compliance requirements.
They should review the UAE legislation, Ministry of Finance guidance and applicable OECD guidance relevant to their circumstances.

Who Is Required to Check UAE Pillar Two?

The first question for a multinational business should be:

Does the MNE group meet the €750 million global revenue threshold?

The UAE DMTT applies to constituent entities that are members of MNE groups with annual global revenue of €750 million or more in the consolidated financial statements of the Ultimate Parent Entity in at least two of the four financial years immediately preceding the financial year in which the UAE DMTT applies.
This means a business should not assess Pillar Two eligibility simply by looking at the turnover of its UAE company.
Instead, the group should review its consolidated global revenue.
Businesses that should consider a Pillar Two eligibility assessment include:
  • UAE subsidiaries of multinational groups
  • UAE branches of multinational businesses
  • UAE entities belonging to international corporate groups
  • Multinational groups headquartered in the UAE
  • Groups with global revenue close to the €750 million threshold
  • Groups already dealing with Pillar Two compliance in other countries
  • Businesses with multiple UAE entities or permanent establishments
What Is the €750 Million Pillar Two Threshold?
The €750 million threshold is one of the most important criteria when determining whether an MNE group may fall within the Pillar Two framework.
The group generally needs to have reached €750 million or more in at least two of the four financial years immediately preceding the relevant financial year.

Example

Suppose an international group has the following consolidated global revenue:
Financial Year Global Revenue
  • Year 1: €820 million
  • Year 2: €790 million
  • Year 3: €650 million
  • Year 4: €600 million
The group exceeded €750 million in two of the four years.
Therefore, it would need to assess whether it falls within the Pillar Two rules for the relevant financial year.
The actual scope assessment can involve additional rules and should be performed using the applicable legislation and guidance.

Does a UAE Company With Low Revenue Need to Consider Pillar Two?

Potentially, yes.
One of the most common misunderstandings about Pillar Two is that a UAE company can determine its position based solely on its own revenue.
That is not how the €750 million threshold works.
A UAE subsidiary could have significantly less than €750 million in local revenue while still being part of an MNE group that meets the global threshold.
For example:
A UAE subsidiary generates €40 million in revenue.
Its multinational parent group generates more than €1 billion in consolidated global revenue.
The UAE company should therefore not automatically assume that Pillar Two does not apply simply because its individual revenue is below €750 million.
The group-level position needs to be assessed first.

Why Is UAE Pillar Two Important?

Pillar Two represents a significant development in international tax compliance.
Large multinational groups may already have extensive tax obligations across multiple countries, including:
  • Corporate Tax
  • VAT
  • Transfer Pricing
  • Country-by-Country Reporting
  • Financial Reporting
  • International Tax Reporting
  • Tax Registrations
  • Tax Return Filing
  • Group-Level Tax Calculations
Pillar Two introduces additional considerations involving global revenue, jurisdictional effective tax rates, GloBE income, covered taxes, substance-based exclusions, top-up tax calculations and reporting.
For businesses with complex international structures, the process can require information from multiple jurisdictions and departments.

How Does the 15% Global Minimum Tax Work?

The Pillar Two framework is based on a 15% minimum effective tax rate for qualifying MNE groups.
However, businesses should understand that this does not mean every UAE company simply pays:
15% – UAE Corporate Tax rate = top-up tax
The calculation is considerably more complex.
Under the GloBE framework, the effective tax rate is calculated using specific rules relating to GloBE income or loss and covered taxes.
Where the relevant jurisdictional effective tax rate is below the minimum rate, a top-up tax calculation may arise.
The UAE Ministry of Finance’s Pillar Two guidance explains that top-up tax is calculated when the effective tax rate in a jurisdiction is below the 15% minimum rate, subject to the applicable rules, exclusions and calculations.
Therefore, businesses should avoid estimating their Pillar Two liability simply by comparing the UAE Corporate Tax rate with 15%.

Does Pillar Two Mean a 6% Additional Tax in the UAE?

No, not automatically.
This is an important point for businesses searching for information about UAE Pillar Two.
The UAE Corporate Tax system and Pillar Two operate under different calculation mechanisms.
The Pillar Two effective tax rate calculation involves specific GloBE rules and adjustments.
Factors such as:
  • GloBE Income
  • Covered Taxes
  • Deferred Tax
  • Substance-Based Income Exclusion
  • Applicable Safe Harbours
  • De Minimis Exclusions
  • Group Structure
  • Other GloBE Adjustments
can affect the final calculation.
Therefore, a business should conduct a proper Pillar Two assessment before determining whether a top-up tax liability exists.

What Is the Substance-Based Income Exclusion?

The Substance-Based Income Exclusion (SBIE) is an important part of the Pillar Two framework.
It is intended to recognise the economic substance that an MNE group maintains in a jurisdiction.
Under the UAE DMTT framework, the substance-based income exclusion considers factors including eligible payroll costs and the carrying value of eligible tangible assets.
This means businesses with employees and tangible assets in the UAE may need to provide relevant information when performing their Pillar Two calculations.
The exclusion does not mean that all UAE businesses are automatically exempt from Pillar Two. Rather, it is one of the elements that may be relevant when determining the amount of top-up tax.

What Is a Constituent Entity Under Pillar Two?

A Constituent Entity (CE) is a group entity that falls within the scope of the Pillar Two rules.
Identifying constituent entities is an important part of the compliance process.
For a multinational group operating in the UAE, the review may involve:
  • UAE Subsidiaries
  • UAE Branches
  • Permanent Establishments
  • Other Entities Included Within the Group Structure
  • Entities That Meet the Applicable Definitions Under the UAE DMTT Rules
The exact treatment depends on the group’s structure and the applicable legislation.
Businesses should therefore prepare an updated group structure chart and identify all UAE operations before completing their Pillar Two assessment.
UAE Pillar Two Registration: What Businesses Should Do
If your group may be within the Pillar Two scope, registration should be approached as part of a broader compliance process.

Step 1: Review global consolidated revenue

Check whether the group meets the €750 million threshold in at least two of the relevant four financial years.

Step 2: Identify the Ultimate Parent Entity

Determine which entity is the group’s Ultimate Parent Entity and review the consolidated financial statements.

Step 3: Map UAE entities

Prepare a list of all UAE companies, branches, permanent establishments and other potentially relevant constituent entities.

Step 4: Assess the UAE DMTT scope

Determine whether the relevant UAE entities fall within the UAE DMTT framework.

Step 5: Gather financial and tax information

Collect the information required for the GloBE/DMTT assessment.

Step 6: Review exclusions and safe harbours

Determine whether any applicable exclusions, elections or safe harbours may affect the group’s calculation.

Step 7: Complete applicable registration

Complete the relevant registration requirements based on the group’s circumstances and the current UAE requirements.

Step 8: Prepare for reporting

Registration should not be treated as the end of the process. Businesses should prepare for applicable reporting and tax obligations.

What Documents and Data Should Businesses Prepare?

Pillar Two compliance can involve significant amounts of information.
Businesses should consider preparing:
Group-level information
  • Consolidated Financial Statements
  • Global Revenue Figures
  • Group Structure
  • Ultimate Parent Entity Information
  • Ownership Information
  • List of jurisdictions where the group operates
UAE entity information
  • Legal Entity Details
  • UAE Tax Registration Information
  • Financial Statements
  • Ownership Structure
  • Branch Information
  • Permanent Establishment Information
Tax information
  • UAE Corporate Tax Information
  • Covered Tax Information
  • Deferred Tax Information
  • Tax Adjustments
  • Relevant Tax Incentives
Operational information
  • Number of Employees
  • Eligible Payroll Costs
  • Tangible Assets
  • Other Information Required for Substance-Based Calculations
Maintaining accurate and consistent information is essential because Pillar Two calculations can depend on data from multiple entities
UAE DMTT and OECD Pillar Two Alignment
The UAE DMTT is closely aligned with the OECD GloBE framework.
The Ministry of Finance issued Ministerial Decision No. 88 of 2025, adopting OECD guidance and commentary on the GloBE Rules issued up to January 2025.
The UAE subsequently received OECD transitional qualified status for its DMTT. The UAE Ministry of Finance also announced that the UAE DMTT qualified for the OECD Pillar Two safe harbour
This provides greater certainty for multinational groups operating in the UAE.
The Ministry’s financial legislation database also lists Ministerial Decision No. 96 of 2026, relating to commentary and agreed administrative guidance for the UAE top-up tax framework.
This demonstrates why businesses should keep their Pillar Two compliance processes updated as new guidance is issued.

What Are the Common UAE Pillar Two Compliance Mistakes?

1. Checking Only UAE Revenue
The most common mistake is assessing the threshold based only on UAE turnover. Pillar Two is based on the group’s consolidated global revenue.
2. Assuming Every Large Group Pays Top-up Tax
Meeting the revenue threshold means the group may be within scope. It does not automatically mean a specific UAE entity has a top-up tax liability.
3. Assuming the Top-up Tax Is Simply 6%
Pillar Two calculations involve specific GloBE rules and should not be reduced to a simple 15% minus 9% calculation.
4. Ignoring Group Entities
Businesses should identify all relevant UAE entities, branches and permanent establishments.
5. Waiting Until Reporting Deadlines
Pillar Two may require information from finance, tax, accounting and group management teams.
Starting late can make data collection more difficult.
6. Using Outdated Guidance
The UAE Pillar Two framework continues to develop.
Businesses should check the latest Ministry of Finance legislation and guidance before making compliance decisions
UAE Pillar Two Registration Checklist
Businesses can use the following checklist as an initial internal review:
  • Confirm whether the group is an MNE group.
  • Review consolidated global revenue for the relevant four-year period.

  • Gather financial and accounting data.
  • Review substance-based information.
  • Assess applicable exclusions and safe harbours.
  • Complete applicable UAE Pillar Two registration requirements.
  • Prepare for reporting and filing obligations.
  • Monitor future Ministry of Finance and OECD guidance.
Frequently Asked Questions About UAE Pillar Two
What is UAE Pillar Two?
UAE Pillar Two refers to the UAE’s implementation of the global minimum tax framework through the Domestic Minimum Top-up Tax (DMTT) for qualifying multinational enterprise groups.
What is the UAE Pillar Two revenue threshold?
The UAE DMTT generally applies to constituent entities of MNE groups with €750 million or more in annual global revenue in the consolidated financial statements of the Ultimate Parent Entity in at least two of the four financial years immediately preceding the relevant financial year.
When did UAE Pillar Two become effective?
The UAE DMTT applies to financial years beginning on or after 1 January 2025.
Does the €750 million threshold apply to UAE revenue?
No. The relevant threshold is based on the MNE group’s consolidated global revenue rather than simply the revenue of an individual UAE entity
Does every UAE company need to register for Pillar Two?
No. Pillar Two is targeted at qualifying MNE groups. Businesses should first assess whether their group meets the relevant threshold and whether their UAE entities fall within the scope of the UAE DMTT.
Does exceeding €750 million automatically create a UAE top-up tax liability?
No. The threshold determines whether the group may fall within the Pillar Two framework. Additional calculations are required to determine whether top-up tax is actually payable.
Is UAE Corporate Tax the same as Pillar Two?
No. UAE Corporate Tax and Pillar Two are separate tax frameworks. A business may have obligations under both regimes.
Is the UAE DMTT rate 15%?
The Pillar Two framework uses a 15% minimum effective tax rate. However, the UAE DMTT calculation is based on specific GloBE rules and does not simply mean that every business is charged a flat 15% tax.
Does a UAE company with less than €750 million revenue fall outside Pillar Two?
Not necessarily. The €750 million threshold is assessed at the MNE group level. A UAE subsidiary can have substantially lower revenue while belonging to an MNE group that meets the threshold
What is a Constituent Entity?
A Constituent Entity is an entity that falls within the relevant scope of the Pillar Two rules. Identifying UAE constituent entities is an important part of determining DMTT compliance obligations.
What is the Substance-Based Income Exclusion?
The Substance-Based Income Exclusion is a mechanism within the Pillar Two framework that takes certain economic substance into account, including eligible payroll costs and tangible assets.
Does the UAE have an Income Inclusion Rule?
The UAE Ministry of Finance states that the UAE currently does not apply the Income Inclusion Rule (IIR), while continuing to monitor its implementation and effectiveness.
Has the UAE DMTT received OECD recognition?
Yes. The UAE Ministry of Finance announced in August 2025 that the UAE DMTT received OECD transitional qualified status and qualified for the OECD Pillar Two safe harbour.
What should an MNE do if it is unsure whether Pillar Two applies?
The group should conduct a formal Pillar Two eligibility and scope assessment covering global revenue, group structure, UAE constituent entities and applicable UAE DMTT requirements before deciding on its compliance obligations.
Why a Pillar Two Eligibility Check Is Important
Pillar Two is a group-level international tax requirement. Determining whether your business is affected requires more than checking the revenue of one UAE company
A proper eligibility assessment can help determine:
  • Whether the MNE group meets the €750 million threshold
  • Whether the UAE DMTT applies
  • Which UAE entities may be in scope
  • What information is required
  • Whether exclusions or safe harbours may be relevant
  • Whether a top-up tax calculation may be required
  • What registration and reporting obligations need to be considered
Early assessment also gives businesses more time to coordinate information between UAE entities, group finance teams and international tax advisers.
Early assessment also gives businesses more time to coordinate information between UAE entities, group finance teams and international tax advisers.
What Should Multinational Businesses Do Now?
If your group operates in the UAE and has €750 million or more in consolidated global revenue in at least two of the preceding four financial years, your business should review its UAE Pillar Two position.
Do not wait until a reporting deadline to begin collecting information.
A practical approach is to:
Check → Identify → Assess → Register → Prepare → Report
First, check whether your group meets the threshold.
Next, identify the relevant UAE entities.
Then assess the UAE DMTT requirements, complete applicable registration and prepare the necessary financial and tax information for future reporting.
Conclusion: Is Your Business Ready for UAE Pillar Two?
The UAE’s implementation of Pillar Two and the Domestic Minimum Top-up Tax represents a major development for multinational businesses operating in the country.
The rules apply to qualifying MNE groups meeting the €750 million global revenue threshold, with the UAE DMTT effective for financial years beginning on or after 1 January 2025.
However, meeting the revenue threshold does not automatically mean that every UAE entity will have a top-up tax liability. Businesses need to conduct a detailed assessment based on their group structure, financial information, covered taxes, applicable exclusions, substance-based calculations and the latest UAE rules.
With the UAE continuing to issue guidance and updates to its Pillar Two framework, staying informed is an important part of maintaining compliance
