If you’re reading this because your UAE finance team said "we think we might be in-scope" or because a group tax director in London or Zurich sent you a GloBE questionnaire, you’re in the right place. This briefing covers the UAE’s version of Pillar Two end to end — scope test, QDMTT mechanics, ETR calculation, interaction with the QFZP 0% rate, safe harbours, and the practical compliance stack that lands with the UAE constituent entity.
Pillar Two in UAE in one paragraph. Scope: Multinational Enterprise Groups with consolidated revenue above EUR 750m in two of the four preceding fiscal years. UAE primary rule: the Domestic Minimum Top-up Tax (QDMTT) under Cabinet Decision 142 of 2024, effective for financial years starting on or after 1 January 2025, which tops the UAE jurisdictional effective tax rate up to 15% on in-scope income. The UAE has NOT implemented IIR or UTPR — QDMTT alone. The QFZP 0% rate is undisturbed for standalone QFZPs; for in-scope MNE QFZPs the QDMTT captures the top-up at UAE level. Transitional CbCR safe harbour available for FY 2024-26 under three tests (de minimis, simplified ETR, routine profits). First QDMTT returns expected during FY 2026, with FTA subsidiary legislation on filing mechanics still rolling out.
1. The scope test — are you in?
Pillar Two applies to a UAE constituent entity of a Multinational Enterprise Group ("MNE Group") where the group’s consolidated annual revenue is above EUR 750m in at least two of the four preceding fiscal years. Three parts to unpack:
- Consolidated annual revenue — from the ultimate parent entity’s consolidated financial statements, prepared under acceptable financial accounting standards (IFRS, US GAAP, UK GAAP, etc.). Includes revenues of all constituent entities after group consolidation adjustments.
- Above EUR 750m — the same OECD GloBE trigger used globally. The UAE converts EUR to AED at the ECB reference rate for the relevant fiscal year, usually around AED 3.15 billion.
- Two of four preceding fiscal years — a test designed to avoid in-and-out treatment for groups hovering around the threshold. Fiscal years prior to the group’s existence count as zero revenue.
Entities excluded from the scope test even inside an in-scope group:
- Government entities, international organisations, non-profit organisations
- Pension funds, investment funds and real estate investment vehicles that are the ultimate parent entity of the MNE group
- Investment entities or insurance investment entities where more than 95% is owned by the above
2. The UAE QDMTT — how the top-up works
The UAE Domestic Minimum Top-up Tax ("QDMTT") was introduced by Cabinet Decision 142 of 2024 and takes effect for financial years starting on or after 1 January 2025. The mechanic:
- Calculate the UAE constituent entity’s GloBE Income (financial accounting net income adjusted for GloBE purposes).
- Calculate the UAE constituent entity’s Covered Taxes (UAE Corporate Tax paid or payable, with GloBE adjustments).
- Calculate the UAE jurisdictional Effective Tax Rate: Covered Taxes ÷ GloBE Income, computed at the UAE jurisdictional level (aggregating all UAE constituent entities).
- Compare to the 15% Minimum Rate. The gap is the Top-up Tax Percentage.
- Apply the Top-up Tax Percentage to Excess Profit (GloBE Income minus the Substance-Based Income Exclusion).
- The resulting figure is the UAE QDMTT payable.
The Substance-Based Income Exclusion (SBIE) protects a slice of profit from top-up on substance grounds: broadly, 5% of payroll costs and 5% of the tangible asset carrying value, both transitioning down from higher percentages (10% / 8% respectively in the first transition year, reducing by 0.2pp each year to 5%). SBIE is a meaningful shelter for substance-heavy UAE operations and essentially nothing for IP-heavy or holding-company UAE operations.
Worked example — QDMTT in action
A European-headed MNE group above EUR 750m has a UAE Free Zone subsidiary that qualifies as a QFZP on qualifying income. The UAE sub’s GloBE Income for FY 2025 is AED 100m, Covered Taxes AED 2m (reflecting a small 9% band of non-qualifying income). Payroll AED 8m, tangible assets AED 20m.
| Step | Calculation | AED (m) |
|---|---|---|
| GloBE Income | After GloBE adjustments | 100.0 |
| Covered Taxes | UAE CT paid (small 9% band on non-qualifying) | 2.0 |
| UAE ETR | 2.0 ÷ 100.0 | 2.0% |
| Top-up percentage | 15% − 2.0% | 13.0% |
| Substance-Based Income Exclusion (first year rates) | 10% × 8 payroll + 8% × 20 assets | 2.4 |
| Excess Profit | 100.0 − 2.4 | 97.6 |
| UAE QDMTT payable | 13.0% × 97.6 | 12.69 |
The UAE QFZP 0% rate still appears on the UAE CT return. The QDMTT return tops the UAE position up to AED 12.69m additional tax, which the UAE collects as QDMTT. The economic effect: the QFZP rate benefit is captured at UAE level rather than passed through to the parent jurisdiction under the IIR. For the parent jurisdiction, the UAE QDMTT is creditable — so no double top-up at parent level.

3. The QFZP 0% rate — still real, but reshaped
Before Pillar Two, the UAE QFZP 0% rate was a stand-alone benefit for Free Zone companies meeting the 5-condition test. Under Pillar Two, two different populations now exist:
- Standalone QFZPs (not in an in-scope MNE group) — QFZP 0% is undisturbed. The economic benefit flows to the UAE entity exactly as it did before.
- In-scope MNE QFZPs (constituent entity of a group above EUR 750m) — QFZP 0% still applies at CT return level, but UAE QDMTT then applies to top the UAE jurisdictional ETR to 15% on in-scope income. The nominal 0% remains; the effective rate becomes 15%.
Three sub-points matter in practice:
- Standalone standalone, not sub-group. The scope test looks at the entire MNE group — not just the UAE sub-group. A UAE-standalone QFZP owned by a non-group HNW individual is standalone; a UAE Free Zone sub inside a group above EUR 750m is not.
- QDMTT does not disqualify QFZP status. Being inside QDMTT scope has no effect on whether the QFZP 5-condition test continues to be met. You can still fail QFZP on substance or de minimis in the normal way; QDMTT is independent.
- Non-qualifying income taxed at 9% is still Covered Tax for GloBE. A QFZP that pays some 9% UAE CT on non-qualifying income builds Covered Taxes that lift the UAE ETR, reducing the QDMTT top-up. The modelling matters.
4. QDMTT alone — where IIR and UTPR fit (or don’t)
The OECD GloBE model has three rules that fit together:
| Rule | Who imposes it | UAE position |
|---|---|---|
| QDMTT Qualified Domestic Minimum Top-up Tax | The source jurisdiction — where the low-taxed income is earned | Implemented from FY 2025 (CD 142/2024) |
| IIR Income Inclusion Rule | The ultimate parent entity’s jurisdiction — or higher-tier intermediate parent | Not implemented in UAE domestic law |
| UTPR Undertaxed Payments Rule | Any constituent entity’s jurisdiction — backstop allocation | Not implemented in UAE domestic law |
The UAE position: QDMTT is the primary rule for in-UAE profits. Where a UAE constituent entity’s ETR is below 15%, UAE collects the top-up as QDMTT. The UAE has not legislated for IIR or UTPR, and does not currently plan to, because QDMTT alone captures the top-up on UAE income — the IIR / UTPR are mechanisms for other jurisdictions to pick up the top-up where no QDMTT applies in the source country. A qualifying UAE QDMTT therefore satisfies the UAE’s primary GloBE obligation.
If a UAE-headed MNE group has low-taxed foreign subsidiaries (a Cayman holdco, say), the IIR applies in another jurisdiction — typically where an intermediate parent sits that has implemented IIR. The UAE parent does not collect that top-up.
5. Transitional safe harbours — FY 2024-2026
The OECD Transitional CbCR Safe Harbour (adopted by the UAE for QDMTT) provides a simplified route to determining that the UAE jurisdictional top-up is zero. Available for fiscal years beginning on or before 31 December 2026 and ending by 30 June 2028. The jurisdictional top-up is deemed zero if ANY of three tests is met:
| Test | Threshold | Note |
|---|---|---|
| De minimis | CbCR Revenue < EUR 10m AND CbCR Profit Before Tax < EUR 1m | Low activity jurisdictions clear easily |
| Simplified ETR | Simplified ETR ≥ transition rate: 15% in FY 2023/24, 16% in FY 2025, 17% in FY 2026 | Transition rate rises each year |
| Routine profits | CbCR Profit Before Tax ≤ Substance-Based Income Exclusion for the jurisdiction | Only substance-return profit; low-ETR flow jurisdictions miss this |
UAE in-scope groups should run the CbCR Safe Harbour tests before the full QDMTT computation. If the Safe Harbour applies for FY 2025 and 2026, the full ETR / Top-up calculation can be deferred. For FY 2027 and beyond, permanent safe harbours become relevant — particularly the QDMTT Safe Harbour which treats UAE QDMTT as satisfying the GloBE top-up where it is a qualifying QDMTT (status expected to be confirmed by the OECD Inclusive Framework).
6. Compliance stack — what UAE Pillar Two filing looks like
For an in-scope MNE Group with UAE constituent entities, the compliance stack includes:
- GloBE Information Return (GIR) — the OECD-prescribed master return covering all jurisdictions, filed either locally in each jurisdiction or (where exchange relationships exist) once by the Ultimate Parent Entity with automatic exchange to other jurisdictions. UAE expected to require local filing until exchange relationships are established.
- UAE QDMTT return — the UAE-specific top-up computation. Filing form and deadline being finalised by the FTA; current indication is the return will be due within 15 months of financial year end (18 months in the first year), aligning with OECD timelines.
- Pillar Two notifications — identifying the UAE Designated Filing Entity (if the UAE sub files the GIR on behalf of the group) or the overseas filer.
- Underlying GloBE calculations — working papers for GloBE Income, Covered Taxes, SBIE, deferred tax adjustments, portfolio shareholding exemptions, qualified refundable tax credits. The documentation burden is similar to a transfer pricing Local File.
⚠ The five Pillar Two mistakes we see most
- Assuming QFZP 0% means zero Pillar Two. QFZP 0% is irrelevant to GloBE — the 15% minimum applies at the UAE jurisdictional level regardless of what the UAE CT return shows.
- Running the ETR on a single-entity basis. GloBE ETR is calculated at jurisdictional level — all UAE constituent entities aggregated. A high-taxed UAE sub can lift a low-taxed UAE sub out of QDMTT territory.
- Treating the transitional CbCR safe harbour as permanent. It expires FY 2026 (FY 2026/27 for off-calendar years). FY 2027 planning starts in H1 2026.
- Forgetting SBIE for substance-heavy UAE operations. SBIE on payroll + tangible assets shelters a meaningful slice of excess profit from top-up — worth modelling to the AED.
- Ignoring deferred tax. GloBE Covered Taxes include deferred tax expense (with specific GloBE adjustments). A UAE entity with large deferred tax liabilities may have a materially higher Covered Taxes figure than the cash CT line suggests — and therefore a materially higher ETR.
Frequently asked Pillar Two questions
Our group revenue is EUR 400m. Does any of this apply?
We’re a UAE Free Zone sub of a US-parented group above EUR 750m. The US has not implemented Pillar Two. What now?
Does QDMTT create double tax at parent level?
How do we calculate the EUR 750m threshold when our group reports in USD?
Can an existing APA or tax ruling protect against QDMTT?
Do we need a Local File / Master File alongside Pillar Two?
What to do next
If you’re inside a group that’s in or near the EUR 750m threshold, the three low-friction next steps are:
- Run the scope test cleanly. Pull the consolidated revenue for the last four fiscal years; convert to EUR; apply the two-of-four test. If you’re not in scope, this guide is background reading only.
- If you’re in scope, run the CbCR Safe Harbour. Three tests — de minimis, simplified ETR, routine profits. Passing any one of them removes the FY 2025/26 top-up and buys you a year to build the full compliance stack.
- If no safe harbour applies, model the QDMTT top-up on your facts — GloBE Income, Covered Taxes, SBIE, deferred tax. Our Outsourced Head of Tax service does this on retainer; one-off Pillar Two readiness reviews are quoted on a Discovery Call.
