What is
QDMTT?
QDMTT stands for Qualified Domestic Minimum Top-up Tax. It is the UAE's implementation of OECD Pillar Two's domestic minimum-tax mechanism. QDMTT applies to multinational groups with consolidated revenue at or above EUR 750 million in at least two of the four prior financial years, bringing the group's effective UAE tax rate up to 15%.
Why does QDMTT exist?
OECD Pillar Two establishes a global minimum effective tax rate of 15% on multinational groups above the EUR 750M revenue threshold. Without a domestic mechanism, the top-up tax on under-taxed UAE income would be collected by foreign parent or sister jurisdictions through the Income Inclusion Rule (IIR) or Undertaxed Profits Rule (UTPR). QDMTT means the UAE collects the top-up tax itself, retaining the revenue domestically.
Who is in scope for UAE QDMTT?
Multinational groups with consolidated revenue at or above EUR 750 million in at least 2 of the last 4 financial years. The threshold applies at the ultimate parent entity level — a group's combined consolidated revenue, regardless of where the parent is located. Most family-office structures, mid-market businesses and HNW principals fall well below this threshold.
How does QDMTT affect Free Zone Persons?
For in-scope groups operating in the UAE through a Free Zone Person structure, the 0% Free Zone Person rate on Qualifying Income no longer delivers its intended economic benefit. The differential between the QFZP effective rate and 15% is collected as QDMTT regardless of QFZP status. The strategic focus for in-scope groups shifts from headline-rate optimisation to substance positioning and the Substance-Based Income Exclusion (SBIE).
What is the Substance-Based Income Exclusion (SBIE)?
SBIE carves out a portion of income tied to tangible assets and payroll from the Pillar Two top-up calculation. Real operational substance — physical premises, employees, decision-making activity — reduces the top-up tax liability. For UAE-based in-scope groups, building substance is no longer optional optimisation; it is the primary lever for managing Pillar Two exposure.
When does QDMTT apply?
The UAE's QDMTT is operational for in-scope groups from the relevant tax periods. Compliance requires the group's UAE entities to engage the Pillar Two data-collection and reporting framework, file QDMTT returns, and operate the substance and transfer-pricing positions defensibly against the 15% effective rate test.
