The Genesis and Evolution: From Tax Haven to Global Tax Standard-Bearer

The introduction and swift evolution of the corporate tax law UAE marks a new era in the nation’s economic landscape, reflecting a paradigm shift from a near tax-free regime toward robust compliance with international standards. As of September 2025, the UAE’s corporate tax regime, stemming from Federal Decree-Law No. 47 of 2022 (as amended by Federal Decree-Law No. 60 of 2023) applies to tax periods beginning on or after 1 June 2023.on the Taxation of Corporations and Businesses, and shaped by a cascade of critical updates, propels the UAE’s legal framework into alignment with the OECD’s BEPS Pillar Two directives.

Key Milestones:

• June 1, 2023: Tax law applies for financial years beginning on or after this date.
• January 1, 2025: Launch of the Domestic Minimum Top-Up Tax (DMTT), operationalizing the OECD’s Global Minimum Tax directive.
• Multiple Amendments & Ministerial Decisions (2023–2025): Ongoing modifications to refine scope, compliance, and enforcement.

Corporate Tax Rates, Scope, and Structure — Clarity Amid Complexity

1. Rates at a Glance:

• 0% on taxable income up to AED 375,000.
• 9% on taxable income exceeding AED 375,000.
• In parallel, the QDMTT ensures a minimum 15% effective rate for in-scope MNEs (EUR 750m revenue threshold) for periods starting on/after 1 Jan 2025.

2. Who Is Subject?

• All companies and commercial activities in the UAE unless explicitly exempted.
• Exemptions:
  • Government entities
  • Natural resource extraction entities
  • Designated public benefit organizations
  • Individuals earning less than AED 1 million per year from licensed business activities (personal income from employment/investments remains exempt). In fact Natural persons are subject to Corporate Tax only if their UAE business turnover exceeds AED 1m in a calendar year. Wages, personal investment income, and real estate investment income remain outside scope.

3. Special Regimes: Free Zone Entities

The UAE’s Free Zone ecosystem offers a 0% rate for entities designated as Qualifying Free Zone Persons (QFZPs) on qualifying income under strict rules:

• Economic substance: Must demonstrate real activity via staff, assets, and expenses.
• De minimis rule: Non-qualifying revenue limited to less than AED 5 million or 5% of total revenue.
• Opt-out: Voluntary participation; breaches revert to standard rates.
• Mainland transactions: 9% tax on non-qualifying income or mainland dealings. Mainland-facing income is not automatically 9%: it’s 0% if it’s qualifying income from qualifying activities (and not an excluded activity) under Cabinet Decision 100/2023 and MD 265/2023; otherwise 9% applies. In fact Mainland transactions are not per se taxed at 9%; several mainland-facing qualifying activities (e.g., distribution from a Designated Zone) can still be 0% if all conditions are met and the income is not from an excluded activity.
• Qualifying Free Zone Persons (QFZPs) benefit from a 0% rate on qualifying income per Cabinet Decision 100/2023, as fleshed out by MD 265/2023 (which repealed MD 139/2023). QFZPs must meet economic substance tests in the free zone, keep within the de minimis cap (non-qualifying revenue ≤ 5% of total or AED 5m, whichever is lower), and prepare audited financial statements. If any condition is breached, QFZP status is lost for the year of breach and the following 4 tax periods.
• Annual audited financial statements are mandatory for QFZPs and taxpayers with revenue > AED 50m (see Ministerial Decision No. 82/2023 and Ministerial Decision No. 84/2025). Tax groups must also prepare audited special-purpose Financial Statements (FTA Decision 7/2025).

The DMTT and Pillar Two: Redefining MNE Strategy in the UAE

What is DMTT?

• Effective January 1, 2025, mandates a 15% minimum tax on UAE profits for MNEs with global revenues > EUR 750 million. In fact, from 1 Jan 2025, the UAE’s QDMTT ensures a 15% minimum effective tax for in-scope MNEs (≥ EUR 750m consolidated revenue), irrespective of incentives/free-zone status.
• “Tops up” any effective tax below 15%—applies irrespective of other incentives or Free Zone status.

Why It Matters:

This closes aggressive tax-planning avenues for large multinationals, ensuring global corporates cannot reduce their worldwide tax bill below the OECD minimum. Businesses must reassess structures, revenue streams, and profit allocations for sustainable efficiency.

Transfer Pricing: The New Audit Frontier

Alignment with OECD best practices makes transfer pricing compliance non-negotiable for UAE firms.

Transfer Pricing Obligations:

• Legal Basis: Federal Decree-Law No. 47 of 2022 and Ministerial Decision No. 97 of 2023.
• Arm’s Length Principle: All related-party transactions must mirror independent market terms.
• Documentation: Local files and benchmarking studies mandatory for qualifying volumes.
• Annual Disclosure: Related-party dealings declared in returns; full documentation on FTA request.

Critical: Inadequate or late documentation incurs significant financial penalties.

Filing, Audit, and Documentation: No Room for Laxity

1. Corporate Tax Registration and Filing

• Register with the Federal Tax Authority.
• Corporate Tax returns are due within 9 months of each tax period end (e.g. if Financial Year ends 31 Dec 2024 then Corporate Tax is due by 30 Sep 2025).

2. Audited Financial Statements

• Mandatory annual audits for accurate tax and transfer pricing calculations. Annual audited financial statements are mandatory for QFZPs and taxpayers with revenue > AED 50m (see Ministerial Decision No. 82/2023 and Ministerial Decision No. 84/2025). Tax groups must also prepare audited special-purpose Financial Statements (FTA Decision 7/2025)
• 2024 audited accounts and TP compliance due by September 30, 2025.

3. Penalties and Enforcement

• Substantial fines for late, false, or missing filings. FTA Decision 3/2024 set phased registration deadlines; late registration can trigger an AED 10,000 penalty (see Cabinet 75/2023, as amended by 10/2024).
• Operational sanctions for inadequate substance or reporting.

Recent Developments as of September 2025

Federal Decree-Law No. 47 of 2022 remains the controlling authority with cumulative amendments. For broader corporate context, see the UAE Commercial Companies Law guide.

• OECD Pillar Two & DMTT: Large MNEs now subject to a 15% minimum tax.
• Banking Sector: Dubai Law 1/2024 imposes a 20% Emirate-level tax on foreign banks (DIFC-licensed activities excluded). Federal Corporate Tax remains payable, but is credited against the Dubai liability; mechanics clarified by Administrative Resolution 107/2024.
• Expanded Reach: New thresholds trigger registration and filing for sole proprietors and SMEs.
