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. 300086921), 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.

Pillar Two Advisory

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

  • 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.

  • 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.

The DMTT obligations in-scope groups face, and the timing that applies to each.

Six Steps

How does the engagement work?

The engagement follows a fixed sequence: a short call, a scope assessment, a written quote, then the modelling, registration and filing work, with your group's reporting calendar driving the timetable.

  1. Request a quote or book a call

    Use the quote form or schedule a free 20-minute call. Our team replies within 30 minutes during business hours.

  2. Scope review

    We assess your group structure, revenue history and UAE entities against the DMTT tests.

  3. Fixed written quote

    You receive a clear fee in writing for the agreed scope before any work starts.

  4. Data collection

    We request the consolidated financials, entity data and tax information the GloBE computations need, in one structured list.

  5. Modelling and safe harbour analysis

    We calculate your jurisdictional effective tax rate, test the reliefs, and report your exposure with a senior accountant's review.

  6. Registration and filings

    We register the group for DMTT through EmaraTax, support the top-up tax return, and coordinate outputs with your head office reporting.

Fixed Fee

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 Bestax

Why choose Bestax for Pillar Two work in Dubai?

Bestax is an FTA Approved Tax Agency (No. 300086921) 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.

Led by Haseeb Hamdani, FCCA and UAE Chartered Accountant, our team advises multinational groups across trading, manufacturing, technology, real estate and financial services.

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.

What Clients Say About Bestax

Groups and finance teams across the UAE on working with our tax practice.

Advisers in business dress talking across a meeting table, with a tablet, printed figures and notepads in front of them.
Had my first corporate tax filing done through Bestax. They offered a tax planning session that was extremely helpful, especially because I was unsure what expenses could be deducted legally. They kinda guided me through the whole process because, as a healthcare professional, I had no clue how things work around here.

Frequently Asked Questions

Book your Free Consultation

If your question is not here, ask it directly.

The DMTT applies to UAE entities of multinational groups with consolidated global revenue of EUR 750 million or more in at least two of the four preceding financial years. It applies for financial years starting on or after 1 January 2025.

Yes. Free zone entities inside an in-scope group are covered, and a 0% or 9% incentive can be the very thing that pulls the group's UAE effective tax rate below 15% and triggers top-up tax. We quantify that impact before it becomes a surprise.

No. UAE corporate tax and the DMTT are separate regimes. Corporate tax applies to your UAE taxable income at its own rates, while the DMTT tops the group's UAE effective tax rate up to 15% under GloBE rules. In-scope groups deal with both.

We start with your group's consolidated revenue for the last four financial years, the group structure, and basic data on each UAE entity. For full modelling we then request financial and tax data through one structured list, so your team isn't drip-fed requests.

Late registration exposes the group to FTA penalties, and it leaves the harder work (the computations and the return) compressed into less time. Registering early costs nothing extra and removes the deadline risk, so we handle it as one of the first steps.

We charge a fixed fee, confirmed in writing after the scope review. The amount depends on your structure, the number of UAE entities and whether safe harbours apply. The initial 20-minute call is free and carries no obligation.
