UAE DMTT Update: Ministerial Decision No. 96 of 2026 Formally Adopts OECD Guidance for MNE Groups

The UAE DMTT Update brings greater certainty for multinational enterprise (MNE) groups after Ministerial Decision No. 96 of 2026 formally adopted the latest OECD guidance. The regime applies to businesses with EUR 750 million (approximately AED 3.15 billion) in consolidated revenue and supports the implementation of the 15% global minimum tax under the OECD Pillar Two framework.

Direct Answer

The UAE DMTT Update under Ministerial Decision No. 96 of 2026, issued on 22 June 2026, formally adopts the latest OECD interpretive guidance for the UAE’s Qualified Domestic Minimum Top-Up Tax (QDMTT) regime. The Decision incorporates three previously pending OECD administrative guidance packages, providing greater certainty for multinational enterprise (MNE) groups that fall within the UAE Domestic Minimum Top-Up Tax framework. The adopted guidance clarifies transitional safe harbour calculations, covered tax definitions, and the treatment of specific entity types. As 2026 marks the first full operational year of DMTT compliance, most in-scope groups with December financial year-ends are expected to submit their first DMTT returns in mid-2027.

Key Points

  • The UAE DMTT Update formally adopts OECD administrative guidance through Ministerial Decision No. 96 of 2026, strengthening the UAE’s Qualified Domestic Minimum Top-Up Tax (QDMTT) framework.
  • Three OECD administrative guidance packages have now been officially incorporated, reducing uncertainty around effective tax rate calculations for multinational enterprise (MNE) groups operating in the UAE.
  • The UAE DMTT applies to multinational groups with consolidated global revenue of EUR 750 million or more (approximately AED 3.15 billion) in at least two of the previous four fiscal years.
  • The regime ensures affected multinational groups pay a minimum 15% effective tax rate on UAE-sourced profits. Where the effective tax rate already reaches 15%, no Domestic Minimum Top-Up Tax is payable.
  • 2026 is the first complete year of DMTT data collection, with most December year-end groups expected to file their first UAE DMTT return during mid-2027.
  • Transitional safe harbours, including the De Minimis Test, Simplified ETR Test, and Routine Profits Test, remain available to reduce or eliminate DMTT liability for qualifying entities.
  • A transitional no-penalty period remains available for tax periods ending before 30 June 2028, provided businesses demonstrate reasonable efforts towards compliance.
  • Businesses using Country-by-Country Reporting (CbCR) data for safe harbour calculations should ensure their reporting aligns with the OECD guidance formally adopted under Ministerial Decision No. 96 of 2026.

UAE DMTT Update: What Ministerial Decision No. 96 of 2026 Changes

When the UAE introduced its Domestic Minimum Top-Up Tax (DMTT) through Cabinet Decision No. 142 of 2024, effective for financial years beginning on 1 January 2025, it aligned the country’s corporate tax framework with the OECD’s Global Anti-Base Erosion (GloBE) Rules under Pillar Two.

Since the original framework was introduced, the OECD has published several rounds of administrative guidance to clarify how the GloBE Rules should be interpreted and applied in practice. These updates addressed technical areas such as covered taxes, safe harbour calculations, and the treatment of specific entities, creating uncertainty for businesses until they were formally recognised under UAE law.

The UAE DMTT Update resolves this uncertainty. Ministerial Decision No. 96 of 2026 officially incorporates three rounds of OECD administrative guidance into the UAE’s Qualified Domestic Minimum Top-Up Tax framework. As a result, multinational enterprise groups now have a single, authoritative reference for preparing effective tax rate calculations, applying transitional safe harbours, and assessing their DMTT obligations under the latest OECD standards.

This formal adoption provides greater consistency, reduces interpretive risk, and enables businesses to prepare for future DMTT filings with increased confidence.

How the UAE DMTT Works Under the Latest Update

Understanding the UAE DMTT Update is easier when viewed alongside the core principles of the UAE’s Qualified Domestic Minimum Top-Up Tax (QDMTT) regime. The table below summarises the key eligibility criteria, effective tax rate calculations, safe harbour provisions, and filing deadlines for multinational enterprise (MNE) groups operating in the UAE.

Element Detail
Who is in scope Multinational enterprise (MNE) groups with consolidated global revenue of EUR 750 million or more (approximately AED 3.15 billion) in at least two of the four preceding fiscal years. The rules apply to UAE entities that form part of those groups.
Rate A 15% minimum effective tax rate applies to UAE Pillar Two income. The Domestic Minimum Top-Up Tax (DMTT) is payable only where the group’s effective tax rate falls below 15%.
Effective tax rate calculation The effective tax rate is calculated under the OECD Pillar Two (GloBE) Rules, rather than the standard UAE Corporate Tax regime. IFRS financial statements form the starting point, followed by the required GloBE adjustments.
Substance-Based Income Exclusion (SBIE) The Pillar Two tax base is reduced by a percentage of eligible UAE payroll costs and the carrying value of qualifying tangible assets. Businesses with genuine economic substance in the UAE may benefit from this exclusion.
De Minimis Safe Harbour A UAE entity may qualify where its average revenue is below EUR 10 million and its average profit (or loss) is below EUR 1 million. Where both conditions are satisfied, no DMTT is payable.
Simplified ETR Safe Harbour Based on Country-by-Country Reporting (CbCR) data rather than a full GloBE calculation. Transitional Effective Tax Rate (ETR) thresholds are 15% for 2024, 16% for 2025, and 17% for 2026.
First filing deadline DMTT returns are generally due 15 months after the financial year-end, or 18 months for the initial filing period. Groups with December year-ends are expected to submit their first returns around June or September 2027.
Transitional no-penalty period Applies to tax periods ending before 30 June 2028, provided businesses can demonstrate that they have taken reasonable measures towards compliance. It is not an exemption for organisations that fail to prepare.

Why the UAE DMTT Update Matters for OECD Safe Harbour Calculations

The UAE DMTT Update provides greater certainty on how OECD transitional safe harbour rules should be applied within the UAE’s Qualified Domestic Minimum Top-Up Tax framework. In particular, the Simplified Effective Tax Rate (ETR) Safe Harbour continues to rely on Country-by-Country Reporting (CbCR) data instead of a full GloBE calculation, making compliance significantly more efficient for eligible multinational enterprise (MNE) groups.

However, the availability of these safe harbours depends on the quality and accuracy of the underlying CbCR information. The allocation of taxes, income, and jurisdictional data must accurately reflect the UAE operations of the group. Errors or inconsistencies in reporting may affect eligibility for the transitional safe harbour provisions.

The OECD administrative guidance formally adopted through Ministerial Decision No. 96 of 2026 also clarifies the treatment of covered taxes, the classification of certain income items, and the application of the rules to specific entity types, including investment entities and insurance companies. Businesses with complex corporate structures or those operating close to the safe harbour thresholds should review their calculations against the latest adopted OECD guidance rather than relying on earlier interpretations or internal position papers.

For multinational groups that delayed finalising their compliance approach while awaiting formal UAE adoption of the OECD guidance, the uncertainty has now been removed. With the first UAE DMTT filing deadlines approaching in 2027, businesses should begin validating their effective tax rate calculations, reviewing safe harbour eligibility, and ensuring that their reporting processes align with the updated UAE DMTT framework.

Frequently Asked Questions

My group has consolidated revenue just above EUR 750 million. Are we in scope?

+
Yes. Under the UAE DMTT Update, multinational enterprise (MNE) groups fall within the scope of the Domestic Minimum Top-Up Tax (DMTT) if their consolidated global revenue exceeded EUR 750 million in at least two of the four preceding fiscal years. Once this threshold is met, the same compliance obligations apply regardless of whether the group is marginally or significantly above it. Businesses should confirm that the two-out-of-four-year test is satisfied and identify which UAE entities qualify as Constituent Entities for DMTT purposes.

Our UAE entity pays Corporate Tax at 9%. Does the DMTT still apply?

+
Potentially, yes. The UAE DMTT Update does not rely solely on the standard UAE Corporate Tax rate. Instead, the Domestic Minimum Top-Up Tax is calculated using the OECD Pillar Two Effective Tax Rate (ETR) methodology. IFRS accounting figures, covered tax adjustments, and GloBE-specific rules can result in an effective tax rate that differs from the statutory 9% Corporate Tax rate. Businesses should therefore perform a full Pillar Two ETR calculation to determine whether a top-up tax is payable.

Can a QFZP paying 0% Corporate Tax on qualifying income trigger DMTT?

+
Yes. Where a multinational group satisfies the EUR 750 million revenue threshold, a Qualifying Free Zone Person (QFZP) may still be subject to the UAE DMTT. Although qualifying income may benefit from a 0% Corporate Tax rate under the UAE Corporate Tax regime, the Pillar Two effective tax rate may remain below the global minimum rate of 15%, potentially creating a DMTT liability. The QFZP incentive applies only within the UAE Corporate Tax framework and does not exempt income from the OECD Pillar Two calculation.

What accounting records are required for UAE DMTT compliance?

+
The UAE DMTT Update requires businesses to maintain robust financial records to support their Pillar Two calculations. DMTT compliance begins with IFRS-compliant financial statements, followed by the required GloBE adjustments. Businesses should also maintain:
  • Records of covered taxes by jurisdiction.
  • Documentation supporting Pillar Two income calculations.
  • Payroll and tangible asset records used to calculate the Substance-Based Income Exclusion (SBIE).
  • Country-by-Country Reporting (CbCR) data supporting safe harbour eligibility.
  • Supporting documentation for all DMTT calculations.
These records should generally be retained for at least seven years in line with UAE record-keeping requirements.
