Scope and impact assessment
We confirm whether your group meets the revenue threshold, which UAE entities are constituent entities, and what the DMTT means for your numbers. Groups near the threshold get a clear in-or-out answer instead of a hedge.
Global Minimum Tax Advisory in Dubai
If your group's consolidated revenue is near or above EUR 750 million and you have entities in the UAE, the 15% global minimum tax now applies to you. The UAE collects it through the Domestic Minimum Top-up Tax (DMTT), and registration deadlines are already running. Bestax Chartered Accountants provides global minimum tax advisory in Dubai for multinational groups. As an FTA Approved Tax Agency (No. 30008692), our cross-border tax team assesses whether your group is in scope, models your effective tax rate under the GloBE rules, and manages DMTT registration and filings with the FTA.

What does our global minimum tax advisory include?
Our service covers the full DMTT cycle for UAE entities of large multinational groups: scope assessment against the EUR 750 million test, effective tax rate modelling, safe harbour analysis, EmaraTax registration, top-up tax return support, and coordination with your group's Pillar Two reporting abroad.
The six workstreams we run
Effective tax rate modelling
The 15% test runs on GloBE rules (the OECD's global minimum tax framework), not on your accounting profit or your UAE corporate tax return. We calculate your jurisdictional effective tax rate the way the rules require, so you know your exposure before the FTA does.
Safe harbour and relief analysis
Transitional safe harbours and the de minimis test can strip most of the compliance burden away for entities that qualify. We test your eligibility first, because the cheapest DMTT computation is the one you don't have to run in full.
Registration and filings
We handle DMTT registration through EmaraTax and support the preparation and filing of top-up tax returns, so deadlines are met without pulling your finance team off their day jobs.
Cross-border coordination
Your UAE position feeds your parent company's Pillar Two reporting, and their rules can claw back tax the UAE doesn't collect. We align the UAE workstream with head office, which pairs naturally with cross-border tax structuring in the UAE where the group's setup itself needs attention.
Free zone impact review
Free zone entities are fully inside DMTT scope, and a 0% incentive can be exactly what triggers top-up tax. We quantify that effect, alongside QFZP tax advisory in the UAE for entities relying on free zone status.
Who needs to act on the UAE DMTT?
The DMTT applies to entities in the UAE that belong to multinational groups with consolidated global revenue of EUR 750 million or more in at least two of the four preceding financial years. It took effect for financial years starting on or after 1 January 2025.
That includes
- UAE-headquartered groups that cross the revenue threshold
- UAE subsidiaries and branches of foreign multinational groups
- Free zone entities within in-scope groups, including those with 0% or 9% incentives
- Groups near the threshold that need a definitive scope answer before deadlines bite
If your group sits below the threshold, the DMTT doesn't apply to you, and we'll tell you that plainly rather than sell you a project you don't need.
What are the key DMTT deadlines?
In-scope groups must register for the DMTT with the FTA and file top-up tax returns. Registration is due within seven months of the end of the first in-scope financial year, with a transitional deadline of 30 November 2026 announced for early periods.
| Obligation | Timing |
|---|---|
| DMTT applies from | Financial years starting on or after 1 January 2025 |
| DMTT registration | Within seven months of the first in-scope financial year end (transitional deadline: 30 November 2026) |
| First top-up tax return | 30 June 2027 for calendar-year groups whose first in-scope year is 2025 |
These dates are new, and new dates move. Deadlines this new tend to move as the FTA issues further decisions. We track them for our clients, and we confirm the dates that apply to your specific financial year during the scope assessment.

How much does global minimum tax advisory cost?
We price DMTT work as a fixed fee, agreed in writing before work begins. The fee depends on your group structure, the number of UAE entities, and whether safe harbours apply, so we confirm it after the scope review.
What you can rely on
- A written, fixed quote before you commit
- No obligation attached to the call or the quote
- Scope agreed upfront, so a registration-only engagement isn't priced like a full computation
Safe harbours change the size of the job
For groups that qualify for safe harbours, the work shrinks substantially, and so does the fee. That's another reason the scope assessment comes first.
Why choose Bestax for Pillar Two work in Dubai?
Bestax is an FTA Approved Tax Agency (No. 30008692) with 10+ years in Dubai, 35+ ACCA and ICAEW trained accountants, operations in four countries, and a 4.8/5 rating across 200+ Google reviews. Senior accountants review every DMTT deliverable before it goes out.
Why that matters for a global minimum tax engagement
FTA Approved Tax Agency status means we deal with the FTA directly on registrations, filings and queries as your registered tax agent in Dubai, so nothing stalls in translation between your group and the regulator.
A cross-border tax practice, not a generalist desk. DMTT sits on top of corporate tax services in the UAE and interacts with transfer pricing services in the UAE, and our team runs all three, so your numbers stay consistent across every filing.
Operations in four countries means we work to group reporting calendars and head office expectations, not just local deadlines.
Senior review on every deliverable protects you where it counts: an ETR computation is only useful if it survives scrutiny.
A physical office in Business Bay at Damac Executive Bay Tower B puts your adviser in the same city as your UAE entities, with everything also available remotely.
The rest of the group's UAE tax position
A DMTT computation is only as sound as the corporate tax, transfer pricing and free zone positions underneath it. The same team runs all of them.
