OECD Pillar Two GIR: What UAE Multinationals Must Do Now

UAE-based multinational groups with consolidated annual revenues of EUR 750 million or more must align their accounting and enterprise data systems with the standardized OECD GloBE Information Return (GIR) framework. Qualifying for transitional safe harbours reduces top-up tax liabilities to zero during early reporting cycles, but securing this relief requires strict reliance on qualified financial statements. Failing to submit verified data through the standardized XML filing architecture exposes groups to foreign top-up tax assessments and cross-border audits.

While domestic policy implementations continue to advance across the Middle East, foreign jurisdictions housing UAE corporate subsidiaries have already enacted Pillar Two rules into binding national legislation. For UAE leadership teams, global compliance is an immediate reality rather than a prospective concern.

Who falls within the scope of GloBE reporting?

The GloBE rules established under the OECD Inclusive Framework apply strictly to multinational enterprise (MNE) groups that meet the consolidated revenue threshold. If your group recorded consolidated revenues of EUR 750 million or more in at least two of the four fiscal years immediately preceding the tested year, your operations are in scope.

This revenue threshold captures two distinct categories of businesses operating within the UAE:

1. UAE-Headquartered Multinationals: Large UAE parent entities with operational subsidiaries, joint ventures, or permanent establishments situated outside the Emirates.
2. Foreign-Headquartered Subsidiaries: UAE-based operating entities, regional headquarters, or free zone branches owned by foreign parent companies subject to Pillar Two in their home jurisdictions.

Even if an entity inside the UAE operates under a qualifying free zone regime with a zero percent corporate tax rate, its revenue forms part of the global group consolidated total. Meeting the EUR 750 million test brings the entire corporate structure under the reporting obligations of the GloBE framework.

Understanding how domestic regulations interact with overseas obligations is vital. For broader context on domestic implementation updates, review our analysis of UAE DMTT Registration and OECD GIR Updates.

What does the GloBE Information Return require?

The GloBE Information Return is a standardized, comprehensive information return designed to provide international tax authorities with the data necessary to evaluate a group's tax liability under Pillar Two. Rather than allowing separate jurisdictions to design bespoke reporting forms, the OECD established a centralized structure governed by an XML schema.

The GIR requires structured disclosures across three core analytical layers:

1. General Group Information and Corporate Structure

This section identifies the Ultimate Parent Entity (UPE), the filing constituent entity, and the corporate ownership chain. It maps every entity, branch, and permanent establishment within the group, detailing direct and indirect ownership percentages and tax identification numbers.

2. Jurisdictional Effective Tax Rate and Top-Up Tax Calculations

For every territory where the group operates, the return demands:

• The determination of GloBE Net Income or Loss, starting from financial accounting net income and applying mandatory GloBE adjustments.
• The computation of Adjusted Covered Taxes, tracking current tax expense, deferred tax adjustments, and cross-border tax allocations.
• The precise Effective Tax Rate (ETR) calculation for the jurisdiction.
• The calculation of any top-up tax owed, including the application of the Substance-Based Income Exclusion (SBIE).

3. Entity-Level Allocations and Safe Harbour Elections

The return records the formal elections made by the group, including the Transitional CbCR Safe Harbour, the UTPR Safe Harbour, and entity-level distributions of top-up tax liabilities under the Income Inclusion Rule (IIR) or Undertaxed Profits Rule (UTPR).

Tax administrations will exchange this information through multilateral competent authority arrangements. To examine how tax agencies manage these data flows, consult our guide on the OECD Pillar Two GloBE Information Exchange Update.

How do filing deadlines and domestic minimum taxes compare across jurisdictions?

Operating across borders requires managing varying local statutory effective dates, domestic minimum tax mechanisms, and administrative requirements. While the core calculation logic stems from the OECD model rules, national transpositions differ in execution.

The table below outlines how key international hubs and the UAE structure these requirements:

The Critical June 2026 Milestone

For multinational groups whose financial year matches the calendar year (ending 31 December), the 18-month transitional rule establishes a major deadline. For the 2024 transition year, the initial GIR submission deadline falls on 30 June 2026.

Subsequent filings return to the standard 15-month schedule, requiring groups to file their 2025 return by 31 March 2027. More detail on meeting this milestone is available in our analysis of the June 2026 GloBE Information Return deadline.

How do the transitional safe harbour tests work?

Full GloBE calculations require up to several hundred distinct data points per jurisdiction, demanding substantial internal resources. The Transitional CbCR Safe Harbour provides temporary administrative relief, deeming the top-up tax in a jurisdiction to be zero when specific conditions are met during the transition period (fiscal years beginning on or before 31 December 2026, but not including a fiscal year ending after 30 June 2028).

To qualify, an operating territory must satisfy at least one of three objective tests, calculated exclusively using data from Qualified Financial Statements and a Qualified Country-by-Country (CbC) Report.

1. The De Minimis Test

The De Minimis Test exempts operational jurisdictions where the multinational group has limited financial scale. A jurisdiction passes if:

• Total CbCR Revenue is less than EUR 10 million, and
• Profit (Loss) before Income Tax is less than EUR 1 million.

If an operational territory satisfies both criteria on its qualified CbC report, the top-up tax for that jurisdiction is treated as zero for that fiscal period.

2. The Simplified ETR Test

The Simplified Effective Tax Rate Test compares the jurisdiction's simplified ETR to the agreed transitional tax rate for the applicable fiscal year. The simplified ETR is calculated by dividing the jurisdiction's Qualified Covered Taxes (drawn from financial statements) by its Profit (Loss) before Income Tax (drawn from the qualified CbC report).

The required statutory thresholds are:

• 15% for fiscal years beginning in 2024
• 16% for fiscal years beginning in 2025
• 17% for fiscal years beginning in 2026

If the simplified ETR meets or exceeds the transitional rate for that year, no top-up tax is levied for that jurisdiction.

3. The Routine Profits Test

The Routine Profits Test assesses whether a territory's financial accounting profit exceeds its substance-based economic baseline. A jurisdiction qualifies if its Profit (Loss) before Income Tax is equal to or less than the Substance-Based Income Exclusion (SBIE) amount calculated under GloBE rules.

The SBIE protects operational substance by carving out an income return based on:

• Eligible payroll costs of eligible employees operating within the jurisdiction.
• The carrying value of eligible tangible assets located in that territory.

During the transitional phase, the OECD rules apply transitional carve-out rates starting at 9.8% for payroll and 7.8% for tangible assets in 2024, gradually declining to a permanent 5% each over a ten-year horizon.

Additional background on transitional mechanics is detailed in our guide on how the OECD eases global minimum tax compliance for UAE businesses.

What data and systems gaps create compliance risks?

The central practical difficulty of the GloBE Information Return lies in financial data integrity. The OECD requires figures used in safe harbour calculations to come directly from Qualified Financial Statements.

Qualified Financial Statements include:

1. The accounts used to prepare the Ultimate Parent Entity's consolidated financial statements.
2. Separate financial statements of each constituent entity prepared under either an Authorized Financial Accounting Standard (such as IFRS or US GAAP) or another recognized accounting standard, provided the data is reliable and adjusted for material distortions.

   │
   └── Management Spreadsheets (Non-qualified adjustments)
         │
         └──► Disqualifies Safe Harbour ──► Triggers Full GloBE Calculation

When corporate finance teams compile CbC reports using unaudited internal management accounts, trial balances with unverified manual adjustments, or hybrid spreadsheets, the report is disqualified as a Qualified CbC Report.

Disqualification brings severe administrative consequences:

• Complete loss of transitional safe harbour protection for the affected jurisdictions.
• Mandatory execution of full, multi-step GloBE calculations across all constituent entities.
• Recalculation of covered taxes, deferred tax assets, and liabilities under strict GloBE principles.
• Increased likelihood of penalties for late or inaccurate administrative filings.

How will tax administrations exchange and audit GIR data?

Under the OECD framework, corporate groups are not required to file separate, full GloBE returns in every operating jurisdiction, provided specific conditions are met:

1. The Ultimate Parent Entity (or an appointed Designated Filing Entity) submits the complete GloBE Information Return to its domestic tax authority.
2. The domestic tax administration maintains an active, operational Qualifying Competent Authority Agreement (QCAA) for the automatic exchange of GIR data with the tax authorities of each jurisdiction where constituent entities operate.
3. The local constituent entities file a localized notification informing their domestic authorities of the identity and location of the filing entity.

Where these conditions are satisfied, foreign tax authorities receive the complete XML dataset automatically from the parent entity's tax administration.

The Role of Cross-Border Data Matching

Tax administrations use automated screening tools to evaluate submitted GIR data against local statutory filings and Country-by-Country reports. If the revenue, payroll, or tax expenses reported in a local statutory tax return do not reconcile with the figures presented in the GIR XML schema, automated alerts are generated.

These mismatches trigger coordinated compliance checks, where multiple national tax authorities jointly audit the multinational group's transfer pricing, substance carve-outs, and GloBE tax allocations.

What practical steps should UAE finance teams take?

Managing GloBE compliance demands structured collaboration across group tax, corporate finance, and IT functions. UAE multinationals must execute a systematic review process across four practical phases.

Implementation Timeline

1. Phase 1: Scope and Entity Mapping (Months 1–2): Review the group corporate structure to identify all constituent entities, joint ventures, and permanent establishments. Confirm whether consolidated revenue crossed the EUR 750 million threshold in two of the last four years.
2. Phase 2: Accounting System Audit (Months 3–4): Verify that CbCR reporting data originates exclusively from Qualified Financial Statements. Audit enterprise resource planning (ERP) charts of accounts to ensure tax provisions and deferred tax items are tagged correctly.
3. Phase 3: Safe Harbour Modeling (Months 5–6): Run the De Minimis, Simplified ETR, and Routine Profits tests across every operational jurisdiction for upcoming reporting years. Identify which territories require full GloBE calculations.
4. Phase 4: XML Schema Alignment and Mock Filings (Months 7–8): Structure data outputs according to the OECD GIR XML schema. Test internal reporting mechanisms to ensure calculations can be completed within standard filing windows.

Compliance Checklist

To ensure operational readiness, corporate finance departments must verify:

• Consolidated financial accounts are audited under an acceptable accounting standard (such as IFRS).
• CbC reporting mechanisms pull data directly from general ledger systems rather than offline spreadsheets.
• Substance-Based Income Exclusion records maintain verifiable payroll logs and fixed asset registers by jurisdiction.
• Local notification requirements are mapped across all foreign jurisdictions where group entities operate.
• Tax allocation agreements exist for sharing top-up tax liabilities across constituent members.

Common Pitfalls to Avoid

• Relying on Unaudited Management Accounts: Using management figures instead of Qualified Financial Statements immediately invalidates transitional safe harbour claims.
• Ignoring the "Once Out, Always Out" Rule: Failing to elect or qualify for a safe harbour in one fiscal year permanently disqualifies that jurisdiction for future transitional years.
• Overlooking Free Zone Tax Asymmetries: Assuming a 0% corporate tax rate in a UAE free zone is immune from Pillar Two top-up taxes imposed by foreign jurisdictions under the IIR or UTPR.
• Delaying ERP System Updates: Postponing general ledger chart-of-accounts adjustments until the filing year leaves insufficient time to extract granular GloBE tax data.

What should UAE businesses do now?

UAE-headquartered multinational groups must decide whether to rely on transitional safe harbours or prepare for full GloBE calculations across their operating footprint. This decision cannot wait for final domestic top-up tax filings. Foreign subsidiaries operating in jurisdictions with active Pillar Two legislation face immediate administrative deadlines, and the validity of safe harbour claims depends entirely on data gathered during the operational year.

The immediate next step is to conduct a formal diagnostic audit of your group's Country-by-Country reporting data against qualified accounting standards. Verifying data inputs now protects your eligibility for safe harbour relief, avoids unnecessary top-up tax assessments abroad, and ensures your corporate reporting architecture is prepared for electronic GIR filings. Engage your finance, legal, and international tax advisors to run multi-jurisdiction safe harbour tests before the initial reporting deadlines close.
