Administrative guidance for an existing regime

In its announcement dated 7 October and published on 8 October 2026, the Federal Tax Authority presents guide TTGREG1 on Top-up Tax scope and registration. The FTA’s catalog records its issue date as 26 August 2026. The October announcement therefore draws attention to an existing guide; it does not itself introduce a new tax. [PRESS] [CATALOG]

The legal basis remains Cabinet Decision No. 142 of 2024 and its Annexure. It applies to fiscal years beginning on or after 1 January 2025. The guide explains the legislation without replacing it: section 2.6 states that it is not legally binding. Establishing an obligation requires checking the applicable provision, the tested fiscal year and the entity’s particular circumstances. [LAW] [GUIDE]

Ministerial Decision No. 96 of 2026 also adopted the OECD’s 2026 consolidated commentary and the documents listed in its Annexure, repealing Decision No. 88 of 2025. An analysis relying only on the first publications of 2025 may therefore overlook the interpretative materials now adopted under UAE law. [COMMENTARY]

Test the group before looking at the local company

Article 1.1.1 of the Annexure covers a multinational group whose ultimate parent entity’s annual consolidated revenue reaches at least EUR 750 million in two of the four fiscal years preceding the tested year. The UAE company’s own revenue does not answer that question. Fiscal years lasting more or less than twelve months, and certain mergers or demergers, require special rules. [LAW]

The group must also qualify as multinational under the legislation. A group operating only in a single jurisdiction does not meet that condition, even if its revenue exceeds the threshold. Conversely, a foreign permanent establishment may be relevant. The legal ownership chart must be reconciled with consolidation and location rules, rather than assuming that a group’s trading name establishes the tax perimeter. [LAW] [PRESS]

For illustration, consolidated revenues of EUR 700, 760, 800 and 730 million for 2021 to 2024 meet the revenue test for 2025: two fiscal years reach EUR 750 million. This example assumes four twelve-month years, correctly converted amounts and no transaction modifying the test. It establishes neither multinational status nor the amount of tax payable. [LAW]

Classify each entity and establish its deadline

Article 2 of the Annexure identifies the entities subject to tax: constituent entities located in the UAE, joint ventures and JV subsidiaries covered by the legislation, and certain reverse hybrid entities created under UAE law. Excluded entities and investment entities require specific examination. Article 2.3 excludes investment entities located in the UAE from Top-up Tax. Group membership alone therefore does not make every vehicle taxable. [LAW]

FTA Decision No. 12 of 2026 normally requires a registration application within seven months after the end of the first fiscal year in which the entity is in scope. Article 2(2) provides a transitional rule: where the fiscal year ends before 30 April 2026, the application must be submitted by 30 November 2026. For a relevant entity whose first applicable year ended on 31 December 2025, that transitional date is therefore the deadline to use. [REGISTRATION]

30 November is not a universal deadline for every group. A different year-end may fall under the ordinary seven-month rule; the fiscal year must itself come within the regime applying from 2025. We recommend recording the first relevant fiscal year, its closing date, the deadline rule adopted and the entity responsible for submission. This record makes it possible to check a conclusion that would otherwise be too broad. [REGISTRATION] [LAW]

Nil tax can leave a registration obligation

Section 8.2 of the guide explains that tax deemed to be zero under a de minimis rule, a safe harbour or the initial phase of international activity does not remove an entity from scope. Registration remains required. The regime’s scope, the relief claimed and the administrative obligation must therefore be assessed separately, with evidence retained for the conditions of the relief. [GUIDE] [LAW]

Appointing a Domestic Designated Filing Entity can organise certain procedures for the members of the domestic group it represents. Article 5 of Decision No. 12 assigns the corresponding applications and notifications to that entity. Its appointment must be documented and its perimeter checked; one application cannot simply be assumed to cover every entity in the worldwide group. [REGISTRATION] [LAW]

Separate registration from the returns

Registration, the Top-up Tax Return and the Pillar Two Information Return are distinct procedures. Ministerial Decision No. 133 of 2026 specifies the entities required to file the information return and the possibilities for filing through a designated entity. Article 2 also provides an exemption from local filing where the conditions for filing in a jurisdiction with a qualifying agreement with the UAE are met; notification to the FTA is still required in that case. [PIR] [LAW]

In practice, the first step is to reconcile the ownership chart, the preceding four years’ consolidated accounts, fiscal year-ends and the classification of UAE entities. Registration deadlines, appointments and return obligations should then be documented separately. Determining the amount of tax requires further analysis: neither the revenue threshold nor the registration guide is sufficient, on its own, to calculate a group’s effective tax burden.
