The UAE’s EmaraTax portal is now open for Pillar Two registration, marking a critical turning point for large multinational groups operating in the country.
Under Cabinet Decision No. 142 of 2024, the UAE implemented the Domestic Minimum Top-up Tax (DMTT) effective for financial years starting on or after 1 January 2025. Every UAE-based Constituent Entity belonging to a group that crosses the EUR 750 million consolidated revenue threshold is now required to register for Pillar Two through EmaraTax.
For in-scope multinationals, the opening of registration is the clearest signal yet that the compliance clock is running. Groups that have not yet assessed their DMTT exposure, reviewed their transfer pricing policies, or begun preparing their data infrastructure now face compressing timelines.
What Is the UAE Domestic Minimum Top-Up Tax?
The UAE’s DMTT aligns with the OECD’s Pillar Two Model Rules, designed to promote equitable tax practices and ensure that multinational corporations contribute fairly to the jurisdictions in which they operate. In practical terms, it imposes a minimum effective tax rate (ETR) of 15 percent on large multinationals generating profits in the UAE.
The UAE Corporate Tax rate stands at 9 percent, but the DMTT adds up to 6 percent as a top-up where the ETR falls below 15 percent. This is not a replacement for corporate tax, it is an additional layer that sits alongside it.
The UAE introduced the DMTT strategically. By introducing the DMTT, the UAE ensured that top-up tax on UAE profits is collected locally rather than being ceded to foreign jurisdictions under the Undertaxed Profits Rule (UTPR). In short, if your group’s UAE operations are undertaxed relative to the global minimum, the UAE collects the shortfall, not another country where your group operates.
Who Is Subject to UAE Pillar Two?
Revenue Threshold
Companies are subject to Pillar Two if they belong to a multinational group with consolidated annual revenues of at least EUR 750 million in at least two of the last four financial years immediately preceding the financial year in which the DMTT applies.
This threshold applies equally to groups headquartered inside and outside the UAE. If your ultimate parent entity is in the UK, France, Japan, or Germany and your group breaches this revenue test, your UAE entities are within scope.
Entities Covered
Entities liable to pay top-up tax include Constituent Entities (CEs), Joint Ventures (JVs), Permanent Establishments (PEs), and Minority Owned Constituent Entities (MOCEs).
Free Zone Entities
A common misconception is that free zone status provides an automatic exemption. UAE free zone entities are not automatically exempt if they belong to an in-scope multinational group. Their ETR must still be assessed under the GloBE framework, and if it falls below 15 percent, a top-up tax obligation will arise.
UAE Pillar Two Registration Requirements
MNE groups in the scope of the DMTT must complete registration with the FTA within the prescribed deadline. Penalties may be imposed for failure to register in a timely manner.
Critically, registration with the FTA for DMTT purposes is a separate registration from UAE Corporate Tax. Groups that are already registered for corporate tax purposes cannot assume their DMTT obligations are covered. The two regimes run through EmaraTax on separate forms, with separate registrations and separate payment cycles.
In-scope groups should treat registration as an immediate priority rather than a step to be addressed alongside the first filing deadline.
Filing Deadlines and the First Compliance Window
Standard and Transitional Timelines
In-scope Constituent Entities and Joint Ventures must submit a Top-up Tax Return to the FTA within 15 months after the end of the relevant tax period, or 18 months for the initial transition year.
For a 31 December 2025 year-end, the first DMTT filing deadline is generally 30 June 2027 under the transitional extension.
What the Filing Covers
The Top-up Tax Return will contain information and reporting requirements equivalent to those under the Pillar Two Information Return, including the option to adopt a simplified jurisdictional reporting framework. Groups should also be aware that potentially 250 or more data points for each constituent entity and joint venture are required to determine the DMTT liability and be disclosed as part of the relevant reporting obligations.
Penalty Relief Window
There is a relief window with no penalties for filing the DMTT return or the Pillar Two Information Return for periods that begin on or before 31 December 2026, provided the group took reasonable measures to apply the rules correctly. This relief does not cover periods that end after 30 June 2028.
This relief does not eliminate the obligation to file, it simply reduces the exposure to administrative penalties for good-faith attempts at compliance during the transition period.
Documentation and Compliance Obligations
Groups should expect to supplement standard Master File and Local File documentation with analyses relevant to Pillar Two, including demonstrating how transfer pricing outcomes affect jurisdictional ETR calculations.
Pillar Two relies heavily on accounting results, making consistent treatment across financial accounts, tax filings, and transfer pricing analyses critical for accurate minimum tax compliance. The DMTT also introduces additional domestic reporting requirements and may necessitate the appointment of a designated filing entity, requiring enhanced data collection, monitoring, and reconciliation across all UAE entities.
Businesses should maintain IFRS accounts, Pillar Two calculations, covered tax records, safe harbour assessments, and supporting documentation for at least seven years.
Strategic Actions for UAE-Based MNE Groups
MNEs should review and recalibrate transfer pricing policies to ensure sustainable levels of local profitability and minimise ongoing top-up tax exposure. Forward-looking modelling enables businesses to assess how pricing structures, functional reorganisations, or operational changes impact minimum tax obligations.
The focus is shifting from rate-driven structuring towards ETR management supported by robust financial data, operational substance, and integrated governance frameworks.
Key steps for any in-scope group operating in the UAE:
- Confirm whether your group meets the EUR 750 million revenue threshold
- Register for DMTT with the FTA as a separate process from corporate tax registration
- Conduct an ETR impact assessment across all UAE constituent entities
- Review existing transfer pricing policies and their effect on UAE profit levels
- Assess eligibility for the Substance-Based Income Exclusion and transitional safe harbours
- Build or upgrade data systems capable of producing the 250-plus data points required per entity
- Align financial reporting, tax accounting, and transfer pricing documentation under a single compliance framework
- Appoint a designated filing entity if your group has multiple UAE constituent entities
Frequently Asked Questions
When did UAE Pillar Two come into effect?
The UAE DMTT applies to financial years beginning on or after 1 January 2025. For most calendar-year groups, the first taxable period under DMTT is 1 January 2025 to 31 December 2025.
What is the Pillar Two minimum tax rate in the UAE?
The global minimum ETR under Pillar Two is 15 percent. Where a UAE entity’s ETR falls below this threshold, the DMTT imposes a top-up tax to bring it to 15 percent.
Does Pillar Two apply to UAE free zone companies?
Yes. Free zone status does not automatically exempt an entity from the DMTT. If the entity belongs to an in-scope multinational group and its ETR is below 15 percent under GloBE rules, a top-up tax may apply.
