UAE constituent entities of multinational groups with consolidated revenue of EUR 750 million or more must register for the Domestic Minimum Top-up Tax on EmaraTax by 30 November 2026, if their first in-scope financial year ended before 30 April 2026. Groups whose first in-scope year ends later simply register within seven months of that year end instead.
This is a countdown piece, not a re-explanation of Pillar Two. If your group runs a 31 December financial year, 2025 was almost certainly your first in-scope year, and the Federal Tax Authority’s registration window closes at the end of this month. Here is exactly what is left to do, week by week, and what follows once the application is submitted.
Key facts
- Registration deadline: 30 November 2026, for groups whose first in-scope financial year ended before 30 April 2026 — most commonly a 31 December 2025 year end.
- Scope threshold: consolidated group revenue of EUR 750 million or more in at least two of the last four financial years, tested at the ultimate parent level, not the UAE entity’s own turnover.
- Standard rule for everyone else: register within seven months of the first in-scope financial year end.
- Who is affected: every UAE constituent entity, subsidiary or branch of an in-scope group, however small its own UAE revenue.
- Next obligations: a Top-up Tax Return due 15 months after year end (18 months in the first transition year), plus a separate Pillar Two Information Return.
- Registration is filed as its own EmaraTax application, separate from corporate tax and VAT registration.
Key takeaways
- Groups with a financial year ending before 30 April 2026 — typically 31 December 2025 — must register for Domestic Minimum Top-up Tax on EmaraTax by 30 November 2026.
- Scope is tested on the global group’s consolidated revenue, so a small UAE subsidiary or branch of a large multinational is still caught, regardless of its own size.
- Registration is a standalone EmaraTax application, separate from corporate tax and VAT registration, and must be filed in its own right.
- Transitional penalty relief protects the Top-up Tax Return and Information Return — it does not cover a missed registration deadline, which is why November’s checklist matters.
Who must register by 30 November 2026
The Federal Tax Authority’s transitional registration rule catches any UAE constituent entity belonging to a group whose consolidated revenue reached EUR 750 million or more in at least two of the last four financial years, where the group’s first financial year falling within the Domestic Minimum Top-up Tax regime ended before 30 April 2026. For most multinational groups that report on a calendar year, that means the year ended 31 December 2025.
The test is applied at group level, using the ultimate parent’s consolidated financial statements — not the UAE entity’s own books. A UAE branch or a modestly sized local subsidiary of a EUR 2 billion global group is still in scope, even if its own UAE turnover is a fraction of that figure. Ministry of Finance guidance on the regime has been consistent on this point since the rules were first issued: size of the UAE presence is irrelevant once the group clears the threshold.
The standard rule: seven months, for everyone else
Not every in-scope group faces the 30 November 2026 date. The general registration rule, which continues to apply once this transitional window closes, requires an entity to submit its tax registration application within seven months of the end of its first in-scope financial year. A group whose first in-scope year ends on 30 June 2026, for example, registers by 31 January 2027 under the standard rule rather than the transitional one. The 30 November 2026 date only applies where that first year end fell before 30 April 2026 — which is why calendar-year groups are the ones facing this month’s deadline.
Week-by-week checklist for the rest of November
With under three weeks left, the practical path is to break the remaining work into stages rather than treat it as one task.
- This week: confirm with head office, in writing, that the group’s consolidated revenue has actually been checked against the EUR 750 million threshold for the relevant four-year window, and get the comparison in two of the last four years confirmed rather than assumed.
- Mid-month: confirm the UAE entity’s own financial year end and establish, on paper, that this was the group’s first in-scope year — the date that triggers the 30 November deadline rather than the seven-month rule.
- Before the final week: gather the EmaraTax registration details — trade licence, UAE legal structure, details of the ultimate parent entity, and a named contact person — so the application itself is not held up by missing documents.
- Final week: submit the Top-up Tax registration application on EmaraTax as a standalone filing, distinct from any corporate tax or VAT application already on file, and keep a dated record of every step taken — who confirmed what, and when.
That dated record matters beyond administrative tidiness; it is also the evidence a group would need if it later had to show the FTA that reasonable steps were taken on time.
What comes after registration
Registration is the first obligation, not the only one. A Top-up Tax Return must be filed with the Federal Tax Authority within 15 months of the end of the relevant tax period — extended to 18 months for the first transition year. For a group with a 31 December 2025 year end, that works out to 30 June 2027. Alongside the Top-up Tax Return, certain groups must also file a separate Pillar Two Information Return, using the FTA’s own template, on the same 15-month timeline. These are two distinct filings covering overlapping information, and both sit on the UAE entity’s compliance calendar from the point of registration onward. Our earlier article on Domestic Minimum Top-up Tax registration and filing deadlines sets out the full deadline table across different year ends, if your group’s financial year does not match the calendar-year example used here.
Transitional penalty relief — and its limits
The Federal Tax Authority has confirmed transitional relief from penalties connected with filing the Top-up Tax Return and the Pillar Two Information Return, for financial years beginning on or before 31 December 2026, provided the group can show it took reasonable measures to apply the rules correctly. That relief is real, but it is narrower than it sounds. It covers the two returns — it does not extend to the registration deadline itself, which means 30 November 2026 carries its own exposure if missed. “Reasonable measures” is also an evidential standard, not a good-faith assumption: a group needs working papers, a record of how figures were sourced, and documented decisions, not simply a claim made after the fact that it tried.
| First in-scope financial year end | Registration deadline | Top-up Tax Return deadline |
|---|---|---|
| 31 December 2025 | 30 November 2026 (transitional rule) | 30 June 2027 (18-month first-year rule) |
| 31 March 2026 | 30 November 2026 (transitional rule) | 30 September 2027 |
| 30 June 2026 | 31 January 2027 (standard 7-month rule) | 31 December 2027 |
What to do now
If your group’s first in-scope financial year ended before 30 April 2026, treat the rest of November as a fixed-deadline sprint: confirm the revenue test with head office, confirm the UAE entity’s year end, assemble the EmaraTax documents, and file the registration as a standalone application. If your first in-scope year falls later, you are on the seven-month rule instead, but the same documentation discipline applies well before that date arrives.
Reflechir Consultancy assists UAE entities with the scope check against the EUR 750 million test, the EmaraTax registration itself, and the bookkeeping records that support it. For the top-up tax computation itself — particularly for groups with multiple UAE entities or complex ownership structures — we coordinate directly with the group’s existing tax advisers, since the calculation sits on top of the group’s global Pillar Two position rather than the UAE entity’s accounts alone.
Frequently asked questions
What happens if we register for Top-up Tax late?
Missing the registration deadline carries an administrative penalty, and registration is one of the few first-cycle obligations that transitional penalty relief does not cover. Groups that realise they are late should register immediately rather than wait, since the exposure grows the longer the application is outstanding, and a prompt correction is generally viewed more favourably than continued delay.
Do we need to register if we don’t expect any top-up tax to be due?
Yes. Registration is a standalone obligation that applies once a group meets the scope test, regardless of whether a safe harbour or the underlying calculation ultimately reduces the UAE top-up tax liability to zero. The registration requirement and the final tax outcome are assessed separately.
Our group’s revenue is close to the EUR 750 million threshold — what should we do?
Ask head office for the actual consolidated revenue figures for each of the last four financial years, not an estimate, since the test requires the threshold to have been met in at least two of those four years. Where the answer is genuinely borderline, document the calculation and the conclusion reached, and revisit it if the group’s position changes in future years.
Does our UAE corporate tax registration already cover this?
No. Domestic Minimum Top-up Tax registration is a separate EmaraTax application from corporate tax and VAT registration, even though all three are administered by the same authority. A group that is already registered for corporate tax still needs to file a distinct Top-up Tax registration if it meets the scope test.
