How the UAE corporate tax 15 percent Pillar Two rule works

What is the UAE corporate tax 15 percent Pillar Two rule?

The UAE corporate tax 15 percent Pillar Two rule is a Domestic Minimum Top-up Tax (DMTT) that brings large multinational groups up to a 15% effective tax rate in the UAE. It applies to multinational enterprises (MNEs) with consolidated global revenue of EUR 750 million or more in at least two of the last four financial years, starting January 2025.

This rule sits alongside the standard UAE Corporate Tax regime. Most UAE businesses pay 0% on the first AED 375,000 of taxable income and 9% above that. Only the largest international groups face the 15% top-up. If you want the wider picture first, read What Is UAE Corporate Tax and the headline UAE Corporate Tax Rates.

Where Pillar Two comes from

Pillar Two is part of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS). More than 140 jurisdictions agreed to a global minimum tax of 15% for large MNEs. The goal is to stop profit shifting to low-tax locations.

The UAE adopted these rules through amendments to Federal Decree-Law 47 of 2022 (the Corporate Tax Law). The DMTT took effect for financial years starting on or after 1 January 2025. The Ministry of Finance confirmed the policy in late 2024 after public consultation.

The three GloBE mechanisms in plain English

Pillar Two uses three connected rules, known as the Global Anti-Base Erosion (GloBE) rules:

• Income Inclusion Rule (IIR): The parent jurisdiction taxes low-taxed income of foreign subsidiaries.
• Undertaxed Profits Rule (UTPR): A backstop that lets other jurisdictions tax low-taxed profits if the IIR does not apply.
• Domestic Minimum Top-up Tax (DMTT): The local country charges the top-up itself, keeping the revenue at home.

The UAE has implemented the DMTT first. This means the top-up tax on UAE-based profits of in-scope MNEs is collected by the UAE Federal Tax Authority (FTA), not by a foreign tax authority.

Who pays the UAE 15% Pillar Two tax?

The DMTT only applies to constituent entities of MNE groups that meet the size threshold. Smaller businesses and purely domestic groups are not affected. For a wider view of who is in and out of the regular regime, see Who Pays Corporate Tax in UAE.

The EUR 750 million test

An MNE is in scope if its consolidated group revenue is EUR 750 million or more in at least 2 of the 4 financial years before the tested year. This matches the OECD threshold used for country-by-country reporting.

The test looks at the ultimate parent entity's audited consolidated financial statements. It includes all revenue lines, not just UAE revenue.

Entities excluded from Pillar Two

Even within a large MNE group, some entities are carved out of GloBE calculations:

• Government entities
• International organisations
• Non-profit organisations
• Pension funds
• Investment funds and real estate investment vehicles that are ultimate parents

How the 15% top-up is calculated

The DMTT is not simply 15% applied to accounting profit. It uses a GloBE Effective Tax Rate (ETR) calculation on a jurisdictional basis. Here is the simplified flow:

1. Start with financial accounting net income for each UAE constituent entity.
2. Apply GloBE adjustments (for example, exclude certain dividends, equity gains, and prior-period errors).
3. This gives GloBE Income for the UAE.
4. Calculate Adjusted Covered Taxes paid in the UAE (mainly the 9% corporate tax).
5. UAE ETR = Adjusted Covered Taxes divided by GloBE Income.
6. If UAE ETR is below 15%, the top-up percentage is 15% minus the actual ETR.
7. Apply the top-up percentage to Excess Profit (GloBE Income minus a Substance-based Income Exclusion).

Substance-based Income Exclusion (SBIE)

The SBIE reduces the profit subject to top-up. It rewards real economic activity. The carve-out is a percentage of:

• Eligible payroll costs of UAE employees
• Eligible tangible assets located in the UAE

The percentages step down over a 10-year transition period, settling at 5% each. So an MNE with significant UAE staff and physical assets pays less top-up than a pure holding structure.

Pillar Two compared with the standard UAE corporate tax

The table below shows how the 15% DMTT differs from the regular regime. For more on the standard tiers, read the UAE Corporate Tax 9 Percent Threshold guide.

Impact on Qualifying Free Zone Persons

A Qualifying Free Zone Person (QFZP) can earn 0% corporate tax on qualifying income. This is one of the most attractive parts of the UAE regime. However, the 15% Pillar Two top-up applies regardless of QFZP status if the group meets the EUR 750 million test.

In practice, a large MNE with a UAE free zone entity will still pay top-up tax on UAE profits that fall below the 15% effective rate. The free zone benefit is preserved for smaller groups and standalone UAE businesses.

Worked example

Assume a UAE subsidiary of a large MNE earns AED 100 million of GloBE Income. It pays AED 5 million of UAE corporate tax. Substance carve-out is AED 20 million.

• UAE ETR = 5 / 100 = 5%
• Top-up percentage = 15% minus 5% = 10%
• Excess Profit = 100 minus 20 = AED 80 million
• Top-up tax due = 10% of 80 = AED 8 million

Filing, registration and compliance

In-scope MNEs must register with the FTA for DMTT purposes. The compliance workflow includes:

• Registration as a constituent entity within set deadlines after the year start
• A GloBE Information Return covering the whole group
• A separate UAE DMTT return and payment
• Maintaining transfer pricing files and country-by-country reports

Failure to register, file, or pay on time triggers administrative penalties under tax procedures law. The FTA has signalled that international standards on transitional safe harbours will be respected during the first years.

Transitional safe harbours

The OECD provided temporary safe harbours through 2026 for MNEs that meet simplified tests using country-by-country reporting (CbCR) data. If a UAE jurisdiction passes a safe harbour test, the group can skip the full GloBE calculation for that year. Three tests are available: a de minimis test, a simplified ETR test, and a routine profits test.

How Pillar Two interacts with other UAE rules

The 15% DMTT does not replace the 9% rate. It sits on top of it for large MNEs. Other interactions to be aware of:

• Small business relief: Available for revenue up to AED 3 million through 2026. Not relevant to Pillar Two because in-scope groups exceed this many times over.
• Tax groups: A UAE tax group files one corporate tax return, but DMTT is calculated on a jurisdictional basis covering all constituent entities.
• Transfer pricing: Arm's length pricing under OECD principles still applies and feeds into GloBE Income.
• VAT: The 5% VAT regime is separate and unaffected.

What UAE finance teams should do now

If your group is in scope, the work is mostly preparation rather than waiting for a tax bill. A practical checklist:

1. Confirm the EUR 750 million test using consolidated accounts.
2. Map every UAE constituent entity, including branches and free zone entities.
3. Identify any Pillar Two carve-outs that apply.
4. Run a draft GloBE ETR for the UAE using prior year figures.
5. Decide if a safe harbour applies for the transition period.
6. Brief the board and audit committee on expected top-up exposure.
7. Update systems to capture GloBE adjustments and SBIE data.

Smaller UAE businesses do not need to act on Pillar Two. Their focus stays on the 9% regime, registration, and timely returns. Read the UAE Corporate Tax hub for the full set of obligations that apply to you.

Official sources

Always confirm details against primary sources. The two most relevant are the UAE Ministry of Finance for policy announcements and the Federal Tax Authority for registration, returns, and guidance.

Pillar Two is a global framework with active updates. New ministerial decisions and FTA guidance can change procedural detail. Your tax adviser should track these and reconcile them against your group accounting policies.
