The UAE has formally adopted the OECD’s Pillar Two is part of the OECD’s global tax reform, aimed at curbing profit shifting by ensuring a 15% minimum effective tax rate for large multinationals worldwide.
The UAE’s DMTT: A Local Mechanism for Enforcing Pillar Two
- Effective from 1 January 2025, the UAE introduced a Domestic Minimum Top-Up Tax (DMTT) through Cabinet Decision No. 142 of 2024. This complements earlier legislation under Federal Decree-Law No. 60 of 2023 and aligns with the OECD’s GloBE Model Rules.
- The existing UAE corporate tax rate of 9% falls below the global standard. The DMTT ensures MNEs subject to Pillar Two pay up to the minimum 15% effective rate.
Who Is Affected?
Not all UAE-based businesses are impacted, this rule targets large multinationals only. The DMTT applies to businesses operating in the UAE that meet both criteria:
- Consolidated global revenues of at least €750 million in at least two of the four preceding fiscal years.
- Members of an MNE group with operations outside the UAE—meaning purely domestic UAE groups without global presence are excluded.
Strategic Impacts for Businesses
- Review and revise your current tax planning strategies, as relying solely on the UAE’s 9% rate is no longer sufficient.
- Enhanced financial reporting and systems are needed to accurately calculate effective tax rates and top-up liabilities.
- Global structuring strategies may require reassessment to maintain efficiency and minimize unexpected tax burdens.
Action Steps for MNEs Operating in the UAE
- Assess global revenue to determine if your group meets the €750 million threshold and crosses borders.
- Model potential top-up liabilities based on your effective tax rate in the UAE.
- Explore temporary exemptions or safe harbours available during the transition phase.
- Upgrade reporting systems to capture required financial data for Pillar Two calculations.
- Investigate upcoming corporate tax incentives, such as R&D credits or high-value employment benefits, to offset potential DMTT exposure.
Now is the time for multinationals to assess exposure, update tax models, and align structures with Pillar Two requirements before enforcement tightens
