What it means for auditors — and why it means nothing for most SMEs
The UAE continues to strengthen its position as a globally competitive business hub while aligning with international tax standards. One of the most significant recent developments is the introduction of the Domestic Minimum Top-up Tax (DMTT) under Cabinet Decision No. 142 of 2024, effective for financial years beginning on or after 1 January 2025.
Although the new rules have attracted considerable attention, the reality is that they apply to only a relatively small number of businesses. Most companies operating in the UAE, particularly small and medium-sized enterprises (SMEs), will not be affected.
In this article, we explain what the DMTT is, who it applies to, and what businesses and auditors should consider.
What is the Domestic Minimum Top-up Tax (DMTT)?
The Domestic Minimum Top-up Tax (DMTT) is part of the OECD’s Pillar Two global minimum tax framework. It is designed to ensure that large multinational enterprise (MNE) groups pay a minimum effective tax rate of 15% on profits generated within the UAE.
Importantly, the DMTT does not replace the UAE Corporate Tax regime. Instead, it operates in addition to the existing Corporate Tax rules.
Where an in-scope multinational group’s effective tax rate in the UAE is below 15%, the DMTT requires payment of a top-up tax to bring the effective tax rate up to the minimum threshold.
Who is subject to the DMTT?
The DMTT applies only to large multinational enterprise (MNE) groups that meet the following criteria:
- Consolidated annual revenue of EUR 750 million or more;
- The revenue threshold is met in at least two of the previous four financial years; and
- The threshold is measured at the level of the Ultimate Parent Entity (UPE) and is determined in Euro, not UAE Dirham.
This means the vast majority of businesses operating in the UAE will remain outside the scope of the DMTT.
Does the DMTT apply to Free Zone companies?
Yes. Being located in a Free Zone does not automatically exempt a company from the DMTT.
If a Free Zone company forms part of an in-scope multinational group and its effective tax rate in the UAE falls below 15%, the DMTT may apply—even where the company qualifies as a Qualifying Free Zone Person (QFZP) and benefits from the 0% Corporate Tax regime.
For large multinational groups, this means that Free Zone tax incentives no longer guarantee an effective tax rate below 15%.
However, Free Zones continue to offer valuable commercial advantages, including:
- Strategic business locations;
- Customs and logistics benefits;
- Licensing flexibility; and
- Access to specialised business ecosystems.
What does this mean for auditors?
The introduction of the DMTT expands the scope of tax considerations during financial reporting and audit engagements for affected groups.
Auditors should expect greater focus on:
- Group-wide financial information;
- Cross-border coordination with overseas finance teams;
- Effective tax rate calculations under the OECD GloBE framework;
- Transfer pricing policies and documentation; and
- Financial statement disclosures relating to minimum taxation.
In addition, DMTT returns are generally required to be filed within 15 months after the end of the fiscal year, with an extended 18-month deadline for the first reporting period.
Who is excluded from the DMTT?
The DMTT does not apply to every business. Certain entities and groups are excluded, including:
- Investment entities;
- Sovereign wealth funds acting as the Ultimate Parent Entity;
- Purely domestic groups with no activity outside the UAE; and
- Groups in the initial phase of international activity, subject to the prescribed conditions.
What does this mean for SMEs?
For most businesses, the answer is simple: nothing changes.
If your business does not belong to a multinational group that meets the EUR 750 million revenue threshold, the DMTT does not apply.
These businesses remain subject only to the existing UAE Corporate Tax regime, including:
- 0% Corporate Tax on taxable income up to AED 375,000 (where applicable under the standard Corporate Tax rules); and
- 9% Corporate Tax on taxable income exceeding that threshold.
There are no additional DMTT filing or payment obligations for businesses outside the scope of the rules.
Why has the UAE introduced the DMTT?
The DMTT aligns the UAE’s tax framework with the OECD’s Pillar Two initiative while ensuring that any applicable top-up tax on UAE profits is collected domestically rather than by another jurisdiction.
The UAE’s rules have also been designed to qualify for the Qualified Domestic Minimum Top-up Tax (QDMTT) Safe Harbour, helping reduce the risk of duplicate taxation for multinational groups.

The introduction of the Domestic Minimum Top-up Tax marks another milestone in the UAE’s evolving corporate tax landscape. While its impact is significant for large multinational groups, the vast majority of UAE businesses—including most SMEs—are not affected.
