Top-up Tax Registration in the UAE: What Multinationals Must Do Before 30 November 2026

If your UAE company belongs to a large multinational group, top-up tax registration in the UAE is now a hard deadline, not a future project. Under FTA Decision No. 12 of 2026, any in-scope UAE entity whose first in-scope fiscal year ended before 30 April 2026 must apply to register for Top-up Tax on or before 30 November 2026. For most groups with a 31 December year end, that means fiscal year 2025, and the cut-off is less than a month away.

This guide explains who must register, how the deadline works, what the EmaraTax application asks for, the role of a Domestic Designated Filing Entity (DDFE), and what follows registration. All facts are as at November 2026.

What the UAE Domestic Minimum Top-up Tax is

The UAE introduced a Qualified Domestic Minimum Top-up Tax (often shortened to DMTT or QDMTT) through Cabinet Decision No. 142 of 2024 on the Imposition of Top-up Tax on Multinational Enterprises. It applies to fiscal years starting on or after 1 January 2025.

The aim is simple. Under the OECD/G20 Pillar Two framework, large groups should pay an effective tax rate of at least 15% in every jurisdiction where they operate. If a group's UAE profits are taxed below that level, the UAE collects the difference locally, rather than allowing another country to collect it. The Ministry of Finance notes that the UAE has chosen not to apply the Income Inclusion Rule at this stage, so the domestic top-up tax is the main Pillar Two charge in the country.

Who must apply for top-up tax registration in the UAE

The rules apply to UAE Constituent Entities of a multinational enterprise (MNE) group whose Ultimate Parent Entity reported consolidated revenue of EUR 750 million or more in at least two of the four fiscal years immediately before the year being tested.

Points that catch groups out:

• Purely domestic groups are out of scope. The FTA has confirmed that groups operating exclusively in the UAE are not covered, whatever their revenue.
• Zero top-up tax does not remove the obligation. According to the FTA's Top-up Tax Guide on Scope and Registration (TTGREG1), an entity that remains within the charging provision must still register even if its top-up tax is deemed to be zero, for example because a safe harbour applies.
• Some entities do not register. Excluded Entities (unless an election has been made not to treat them as excluded) and Investment Entities located in the UAE are not subject to Top-up Tax and, per the FTA guide, are not required to register.
• Joint ventures and permanent establishments need to be mapped too. The FTA guide covers Permanent Establishments, Joint Ventures, Flow-through Entities and Hybrid Entities in detail, and advisers such as DLA Piper recommend including them in the scoping exercise.

The registration deadlines under FTA Decision No. 12 of 2026

FTA Decision No. 12 of 2026, issued on 16 July 2026, sets two rules.

KPMG's reading is the same: for most in-scope groups with a 31 December year end, the 30 November 2026 date applies, and it also applies to non-calendar year ends that finished before 30 April 2026.

The same decision also covers the other end of the life cycle. Deregistration must normally be applied for within 6 months of the entity ceasing to exist or leaving the group, and only once all Top-up Tax, penalties, Top-up Tax Returns and Pillar Two Information Returns are settled and filed. Groups that drop out of scope file an out-of-scope notification within 6 months of the end of the tested year.

Penalty for missing the deadline

The FTA guide states that an administrative penalty of AED 10,000 applies where an entity fails to submit its registration application within the relevant timeline. Where a DDFE fails to register the group members it represents, the AED 10,000 penalty applies for each entity it failed to register. The FTA may also register an entity on its own initiative using the information available to it.

For a group with several UAE subsidiaries, free zone companies and branches, that per-entity penalty adds up quickly. For the wider UAE penalty landscape, see our guide to UAE tax penalties in 2026.

How to register for Top-up Tax on EmaraTax

Registration is made through the FTA's EmaraTax portal. Based on the FTA guide, the practical sequence is:

1. Confirm scope and the first in-scope fiscal year. Check the EUR 750 million test across the four preceding years using the Ultimate Parent Entity's consolidated accounts.
2. List every UAE entity in scope. Include branches, joint ventures and JV subsidiaries, and identify any Excluded or Investment Entities.
3. Decide on the filing structure. Choose whether each entity registers itself or a DDFE registers on behalf of the domestic group.
4. Use the right EmaraTax profile. If the entity is already registered with the FTA for another tax (for example Corporate Tax or VAT), it uses the same "Taxable Person" to register for Top-up Tax. If not, it must first create a Taxable Person and a Tax Identification Number (TIN). The same applies to a DDFE and to any group member not yet known to the FTA.
5. Prepare the supporting documents. The FTA guide lists: a document verifying the name and TIN of the Ultimate Parent Entity, where it is located outside the UAE; a document verifying the name and TIN of the Designated Filing Entity, where it is located outside the UAE (if applicable); and an overview of the MNE group's corporate structure.
6. Submit and respond. The FTA reviews the form and may ask for more information. On approval it issues a Pillar Two TRN to each entity, and for the group where a DDFE is appointed. A rejected application can be resubmitted once the reasons are resolved.

Allow time for FTA information requests before the deadline.

Domestic Designated Filing Entity: should you appoint one?

Article 5 of FTA Decision No. 12 of 2026 provides that where a DDFE is appointed, it submits the registration, deregistration and in-scope or out-of-scope notifications on behalf of all members of the relevant domestic group. Per the FTA guide, the DDFE must register every member it represents, even those with deemed zero top-up tax.

A DDFE concentrates responsibility in one entity, which simplifies administration for groups with many UAE companies. The trade-off is that the DDFE needs EmaraTax access, timely group data and clear internal controls, because a single missed filing can trigger penalties across every entity it represents.

What comes after registration

Registration is only the first step. In-scope groups then need to prepare for:

• The Top-up Tax Return and payment. EY reports that under Cabinet Decision No. 142 of 2024 the return is due within 15 months after the end of the fiscal year, extended to 18 months for the first year, with payment made alongside the return.
• The Pillar Two Information Return. Ministerial Decision No. 133 of 2026 sets out who files it. The FTA guide describes four options: each UAE entity files; a Designated Local Entity files a single return for the UAE entities; or the return is filed by the Ultimate Parent Entity or a Designated Filing Entity in a jurisdiction that has a Qualifying Competent Authority Agreement in effect with the UAE.
• Transitional penalty relief. EY notes that no penalties apply to filing the return or the information return for periods beginning on or before 31 December 2026 (but not periods ending after 30 June 2028) where the group has taken reasonable measures to apply the rules correctly. That relief concerns returns; it does not change the registration deadline.
• Free zone positions. DLA Piper suggests that Qualifying Free Zone Persons should reassess whether keeping that status still pays once Top-up Tax is factored in. Our guide to the QFZP 0% corporate tax regime explains those conditions.

Your four-week action list

1. Confirm in writing whether the group meets the EUR 750 million test.
2. Map all UAE entities and their fiscal year ends.
3. Decide on a DDFE and, for the information return, a Designated Local Entity.
4. Collect UPE and Designated Filing Entity TIN evidence and a group structure chart.
5. Check that each entity has an active EmaraTax Taxable Person profile.
6. Submit applications well before 30 November 2026 and track FTA queries daily.
