Critical September 2025 Deadline: Are You Ready?

For businesses operating with a December 31, 2024 financial year-end, the clock is ticking toward the September 30, 2025 corporate tax filing deadline. This represents the first full-year filing under the UAE's revolutionary 9% corporate tax regime, and non-compliance carries severe consequences:

Late filing penalties: AED 500 per month for the first 12 months, escalating to AED 1,000 monthly thereafter
Registration penalties: Up to AED 10,000 for delayed registration
Under-reporting fines: Up to 300% of unpaid tax in severe cases
Audit triggers: Repeated delays may result in comprehensive FTA audits

Game-Changing DMTT: 15% Minimum Tax Takes Effect

The most significant development in UAE corporate tax 2025 is the implementation of the Domestic Minimum Top-up Tax (DMTT), effective January 1, 2025. This revolutionary measure aligns the UAE with OECD Pillar Two global standards and impacts multinational enterprises with:

Who's Affected by DMTT?

Multinational enterprises (MNEs) with consolidated global revenues of €750 million (≈ AED 3 billion) or more
Companies operating in at least two of the four preceding financial years above the threshold
Free zone entities that are part of qualifying MNE groups may lose their 0% tax advantage

Strategic Implications

The 15% minimum effective tax rate ensures that UAE-based operations of large multinationals contribute fairly to local revenues, preventing profit-shifting strategies that previously allowed sub-15% effective rates.
