Updated August 2026. The UAE adopted the OECD/G20 Pillar Two global minimum tax framework through Cabinet Decision No. 142 of 2024, introducing a Qualified Domestic Minimum Top-up Tax (QDMTT) effective for financial years commencing on or after 1 January 2025. Large multinational enterprise (MNE) groups with consolidated global revenue of EUR 750 million or more — approximately AED 2.9 billion — in at least two of the four preceding fiscal years are in scope. The Federal Tax Authority (FTA) administers QDMTT compliance under the umbrella of the UAE Corporate Tax system. Compliance costs for in-scope MNEs operating in the UAE range from AED 300,000 to AED 2,000,000 per year depending on group complexity and the number of UAE constituent entities.
- UAE’s QDMTT ensures that the UAE — not a foreign jurisdiction — collects the 15% top-up tax on UAE-sourced profits of in-scope MNEs, protecting UAE’s tax base.
- The EUR 750 million (approx. AED 2.9 billion) consolidated revenue threshold applies at group level; any MNE meeting this threshold across its global operations is in scope, including free zone entities.
- Free zone entities (QFZPs) paying 0% corporate tax on Qualifying Income face the QDMTT where their Effective Tax Rate (ETR) falls below the 15% global minimum.
- The GloBE Income Inclusion Rule (IIR) and Undertaxed Profits Rule (UTPR) provide the backstop — where UAE collects QDMTT, parent-jurisdiction IIR/UTPR do not apply to UAE profits.
- GloBE Information Returns (GIR) must be filed with the FTA for in-scope groups; the filing deadline is 15 months (18 months for the transition year) after the end of the fiscal year.
What Is Pillar Two and Why Does It Matter for UAE?
The OECD/G20 Inclusive Framework’s Pillar Two rules — also called the Global Anti-Base Erosion (GloBE) rules — establish a global minimum effective tax rate (ETR) of 15% for large MNE groups. Where an MNE’s constituent entities in a given jurisdiction pay an ETR below 15%, a “top-up tax” is charged to bring the effective rate to 15%. Pillar Two was designed to end the “race to the bottom” in corporate tax rates and curtail profit-shifting to low- or zero-tax jurisdictions.
For the UAE, Pillar Two is significant for two reasons. First, the UAE’s standard corporate tax rate is 9% (below 15%), and the UAE’s free zone regime offers a 0% rate for Qualifying Free Zone Persons — both rates are below the 15% global minimum. Without a UAE QDMTT, the top-up tax would have been collected by the parent-jurisdiction tax authority of the MNE (e.g., the Netherlands, UK, Germany, or another jurisdiction that has implemented Pillar Two IIR). By introducing a QDMTT, the UAE retains the revenue in-country while satisfying its Pillar Two commitments. Second, large MNEs making investment decisions for the UAE must now model the QDMTT cost in their after-tax return calculations alongside the standard 9% corporate tax.
As of August 2026, over 140 countries have adopted or committed to Pillar Two rules, with EU member states, UK, Switzerland, South Korea, Japan, and many others fully enacted. MNEs headquartered in these jurisdictions face parent-company IIR exposure on UAE profits if the UAE QDMTT is not satisfied — making QDMTT compliance directly linked to parent-entity tax obligations globally.
The EUR 750 Million Threshold: Who Is In Scope?
An MNE group falls within UAE QDMTT scope if its consolidated annual revenue exceeded EUR 750 million (approximately AED 2.93 billion at August 2026 rates; the OECD uses EUR as the reference currency) in at least two of the four fiscal years immediately preceding the current fiscal year. This is a global group-level threshold — not a UAE-only revenue test. A group with only AED 50 million of revenue in the UAE but EUR 800 million globally is fully in scope.
The threshold determination uses the consolidated financial statements of the Ultimate Parent Entity (UPE). New MNE groups created through mergers or acquisitions that meet the threshold based on combined historical revenue fall within scope from the first year of operation. Groups with revenues fluctuating around the threshold should assess their position each year using the four-year lookback.
Excluded entities — sovereigns, international organisations, non-profit organisations, pension funds, investment funds that are UPEs, and real estate investment funds that are UPEs — are carved out of GloBE scope. Note that subsidiary-level participation by these entities does not exclude the overall group if other parts of the MNE meet the threshold.
UAE QDMTT: How It Works
The UAE Qualified Domestic Minimum Top-up Tax (QDMTT) applies a top-up charge equal to the difference between 15% and the UAE Effective Tax Rate (ETR) on the GloBE Income of UAE constituent entities. The ETR for each jurisdiction is calculated as: ETR = Adjusted Covered Taxes ÷ GloBE Net Income. GloBE Net Income starts from the financial accounting profit of each UAE constituent entity, adjusted for specific GloBE add-backs and deductions (e.g., excluded dividends, excluded equity gains, and specific policy disallowances).
Covered Taxes include the UAE Corporate Tax payable (at 9% or 0% for QFZPs on Qualifying Income) plus deferred tax amounts calculated under the GloBE framework. The Substance-Based Income Exclusion (SBIE) carves out a portion of GloBE Income equal to 5% of the payroll costs and 5% of the carrying value of tangible assets of UAE entities — this exclusion reduces the GloBE Income subject to the QDMTT, rewarding real economic substance in the UAE. During the transition period (2025–2032), the SBIE percentages are higher: 10% of payroll and 8% of tangible assets in 2025–2026, stepping down annually to 5% by 2033.
The QDMTT is calculated and filed at the UAE jurisdiction level — all UAE constituent entities of the in-scope MNE group are aggregated. The filing is done through the FTA’s CT portal as part of the annual GloBE Information Return (GIR). QDMTT is due at the same time as the CT return filing — 9 months after the end of the fiscal year.
Free Zone Impact Under Pillar Two
Qualifying Free Zone Persons (QFZPs) that pay 0% corporate tax on Qualifying Income present the most significant Pillar Two exposure for UAE-based MNEs. Where a QFZP’s GloBE ETR across the UAE jurisdiction falls below 15%, the QDMTT applies to the entire in-scope UAE group (not just the QFZP). This creates a complex interaction: the 9% standard CT rate and 0% QFZP rate are blended in the jurisdiction-wide ETR calculation.
In practice, the impact on specific free zones depends heavily on: (1) whether the QFZP’s activities generate Qualifying Income subject to 0% (e.g., inter-company transactions, qualifying manufacturing); (2) the magnitude of the SBIE relative to the GloBE Income — large-substance operations (many employees, significant tangible assets) benefit most from the SBIE carve-out; and (3) the mix of 0% and 9% income within the UAE jurisdiction. Free zone groups with large UAE payrolls and fixed assets may find that SBIE entirely eliminates or substantially reduces their QDMTT exposure.
Free zone economic substance in the UAE is now directly rewarded under Pillar Two through the SBIE — this is a significant structural advantage for MNEs that have built genuine, people-and-asset-intensive operations in UAE free zones rather than using them as paper holding structures.
Top-Up Tax Calculation Examples
Example A — High-substance QFZP: UAE free zone entity, GloBE Income = AED 100M, Covered Taxes = AED 0 (0% QFZP rate on all income), Payroll = AED 30M, Tangible Assets = AED 200M. SBIE (2026 rates) = 10% × AED 30M + 8% × AED 200M = AED 3M + AED 16M = AED 19M. Excess GloBE Income = AED 100M − AED 19M = AED 81M. QDMTT = 15% × AED 81M = AED 12.15M.
Example B — Low-substance holding: UAE free zone holding company, GloBE Income = AED 50M, Covered Taxes = AED 0, Payroll = AED 0.5M, Tangible Assets = AED 5M. SBIE (2026) = 10% × AED 0.5M + 8% × AED 5M = AED 0.05M + AED 0.4M = AED 0.45M. Excess GloBE Income = AED 50M − AED 0.45M = AED 49.55M. QDMTT = 15% × AED 49.55M = AED 7.43M.
These examples illustrate why building real economic substance in the UAE remains critical under Pillar Two — the SBIE can materially reduce QDMTT liability for entities with large genuine operations.

GloBE Rules: IIR and UTPR
The GloBE framework has three charging rules. The Qualified Domestic Minimum Top-up Tax (QDMTT) is the UAE-level top-up tax applied first. The Income Inclusion Rule (IIR) is applied by the parent entity’s jurisdiction — where the UAE QDMTT is a Qualified QDMTT (which the UAE’s is, having been qualified by the OECD Inclusive Framework), the IIR in the parent jurisdiction is reduced by the QDMTT paid in the UAE. This means that paying UAE QDMTT prevents a second top-up charge from being levied by, say, the Netherlands or UK on the same UAE profits. The Undertaxed Profits Rule (UTPR) is the backstop — applied by non-parent-jurisdiction group members to mop up any residual undertaxed profits not caught by the IIR.
For practical purposes, in-scope MNEs should model their global GloBE position at group level, identify all jurisdictions where ETR falls below 15%, and assess whether local QDMTTs or domestic top-up taxes will be applied (preventing IIR collection at parent level). UAE’s qualified QDMTT is designed to achieve precisely this outcome for UAE-sourced profits.
Timeline for UAE Pillar Two Implementation
UAE Cabinet Decision No. 142 of 2024 confirmed: QDMTT effective date — 1 January 2025 (for fiscal years commencing on or after this date). GIR filing deadline — 15 months after fiscal year end for standard years (18 months for the transition year 2025). QDMTT safe harbour from IIR/UTPR — UAE’s QDMTT is a Qualified QDMTT under the OECD framework, providing the “QDMTT safe harbour.” FTA guidance on QDMTT calculation — issued Q1 2025, with updated guidance anticipated Q4 2026 addressing free zone entity interactions and holding company structures.
Which MNEs are subject to UAE QDMTT?
Any MNE group with consolidated global revenue of EUR 750 million or more in at least two of the preceding four fiscal years is in scope, regardless of where the UPE is incorporated. If any constituent entity of the group has operations (a tax-resident entity, branch, or permanent establishment) in the UAE, that UAE entity’s GloBE Income is subject to QDMTT if the UAE ETR falls below 15%. UAE-headquartered MNE groups are subject to the same threshold — if a UAE group grows above EUR 750M consolidated revenue, it enters QDMTT scope.
Does Pillar Two apply to UAE free zone companies?
Yes. Free zone entities — including QFZPs paying 0% on Qualifying Income — are constituent entities for GloBE purposes if they are part of an in-scope MNE group. Their 0% tax rate contributes to a lower UAE ETR, which may trigger QDMTT on the excess GloBE Income above the Substance-Based Income Exclusion. The SBIE rewards genuine economic substance (payroll, tangible assets) in the UAE, so free zone entities with large real operations have materially lower QDMTT exposure than pure holding structures.
Can the UAE QDMTT be reduced by tax incentives or credits?
The GloBE framework distinguishes between Qualified Refundable Tax Credits (QRTCs) — which are treated as income (increasing GloBE Income) and reduce the QDMTT — and Non-Qualified Refundable Tax Credits (NQRTCs) — which are treated as income but do not reduce covered taxes. UAE investment incentives, sector-specific subsidies, and government grants must be analysed individually to determine their GloBE classification. The FTA has issued guidance on how specific UAE incentive schemes are treated; businesses receiving material incentives should obtain a QDMTT-specific technical analysis from a qualified tax adviser.
What is the GloBE Information Return (GIR) filing requirement?
The GloBE Information Return (GIR) is the annual filing required of in-scope MNE groups to report their GloBE calculations to the FTA. The GIR includes: entity-level GloBE Income and Covered Taxes data for all UAE constituent entities; SBIE calculations; QDMTT calculations; and treaty-required information for automatic exchange. UAE constituents of groups where the UPE is in another jurisdiction may be able to file a surrogate GIR if the UPE’s jurisdiction has an exchange agreement with the UAE. GIR preparation and filing costs range from AED 100,000 to AED 500,000 depending on group complexity.
How does Pillar Two interact with UAE double tax treaties?
The UAE has an extensive network of over 140 double tax treaties (DTTs). Pillar Two is intended to operate alongside, not replace, existing DTTs. The QDMTT is a domestic UAE tax — it does not give rise to a treaty refund right for the taxpayer, as it is applied domestically. Parent-jurisdiction IIR may be affected by the UAE’s treaty network in limited circumstances — the OECD’s Subject to Tax Rule (STTR), a separate Pillar Two component, may also affect treaty source-taxation rights in certain cases. MNEs with UAE operations should review their group’s DTT exposure in conjunction with Pillar Two modelling.
