UAE Tax Reporting Rules for Multinational Companies

UAE tax reporting rules for multinational companies have entered a new phase in 2026, as the Ministry of Finance moves to sharpen the country’s implementation of the global minimum tax regime. On August 26, 2026, the Ministry issued Ministerial Decision No. 133 of 2026, a measure that spells out precisely which entities operating within the UAE must submit a Pillar Two Information Return to the Federal Tax Authority. For multinational enterprise groups with a presence in the country, this is not a new tax. It is, instead, a long-awaited clarification of who is responsible for reporting under a framework that has been building since 2024, and it removes a good deal of the guesswork that group tax teams have been navigating for the past year.

Understanding the Background UAE Tax Reporting Rules Cabinet Decision No. 142 of 2024

To appreciate why this decision matters, it helps to look at where it comes from. The UAE introduced its Top-Up Tax framework for multinational enterprises through Cabinet Decision No. 142 of 2024. That decision aligned the UAE with the OECD/G20 Inclusive Framework’s Pillar Two Global Anti-Base Erosion Rules, commonly referred to as the GloBE Rules. Under Pillar Two, large multinational groups, generally those with consolidated global revenues above EUR 750 million, are expected to pay an effective tax rate of at least 15 percent in every jurisdiction where they operate. Where a group’s effective rate in a given country falls below that threshold, a top-up tax applies to bring it up to the minimum.

The UAE’s participation in this framework reflects a broader shift in the country’s tax identity. Long known as a low-tax, business-friendly jurisdiction, the UAE has spent the last several years building a modern tax architecture, introducing VAT in 2018, federal corporate tax in 2023, and now a Domestic Minimum Top-Up Tax that applies specifically to in-scope multinational groups for financial years beginning on or after January 1, 2025. Ministerial Decision No. 133 of 2026 is best understood as the operational layer sitting on top of that 2024 framework. It does not change who owes the top-up tax. It changes, and clarifies, who must tell the Federal Tax Authority about it.

Who Must File the Pillar Two Information Return

The heart of the new decision is a simple but important question: which UAE entity within a multinational group actually carries the filing obligation? The Ministry has answered this by identifying three categories of entities required to submit a Pillar Two Information Return.

The first category covers every Constituent Entity located in the UAE, with the exception of Investment Entities. A Constituent Entity, in Pillar Two terminology, is broadly any entity that forms part of a multinational enterprise group falling within the scope of the GloBE Rules, whether that is a subsidiary, a branch, or another form of taxable presence. By excluding Investment Entities from this general obligation, the Ministry has recognised that funds and similar vehicles are typically treated differently under the GloBE framework, given their distinct ownership and income structures.

The second category extends the obligation to every Joint Venture and Joint Venture Subsidiary located in the UAE. This detail matters more than it might first appear. Multinational groups often structure regional operations through joint ventures rather than wholly owned subsidiaries, particularly in sectors like real estate, energy, and infrastructure that are common in the UAE market. By explicitly bringing joint ventures and their subsidiaries into scope, the decision ensures that the reporting net is not limited to the conventional, fully consolidated corporate structure of a group.

The third category is more technical but no less significant. It applies to every Stateless Constituent Entity that qualifies as a Reverse Hybrid Entity created under UAE law. Reverse hybrid entities are structures that are treated as transparent for tax purposes in one jurisdiction and opaque in another, and they have historically been a point of complexity in cross-border tax planning. Bringing UAE-established reverse hybrid entities explicitly within the filing obligation closes a potential gap and signals that the UAE intends its Pillar Two implementation to be comprehensive rather than selective.

How the UAE Tax Reporting Rules for Multinational Companies Return Can Actually Be Filed

Alongside identifying who must report, the decision also clarifies how the information return can be submitted, and this is where multinational groups gain some welcome operational flexibility. A Constituent Entity, Joint Venture, or Joint Venture Subsidiary can file its Pillar Two Information Return directly with the Federal Tax Authority. Alternatively, the filing can be handled centrally through a Designated Local Entity acting on behalf of the group’s other UAE entities.

This second option is likely to be the more practical route for larger groups with multiple UAE entities spread across different emirates or free zones. Rather than requiring every constituent entity to independently manage its own submission, a group can nominate one UAE entity to consolidate and file on behalf of the others. For multinational tax and finance teams, this mirrors the kind of centralised compliance model already familiar from country-by-country reporting under BEPS Action 13, and it should reduce duplication of effort as well as the risk of inconsistent filings across a group’s UAE footprint.

Why This Clarity Matters for Multinational Groups

Since Cabinet Decision No. 142 of 2024 first introduced the Top-Up Tax, in-scope groups have generally understood that reporting obligations were coming, but the precise mechanics of who files, and how, had not been fully settled. Ministerial Decision No. 133 of 2026 fills that gap. For a jurisdiction competing to remain an attractive base for regional and global headquarters, that kind of specificity carries real weight. Multinational tax directors need to know, well in advance of a filing deadline, exactly which legal entity within their UAE structure is on the hook for a return, and what happens when that structure includes joint ventures or unusual hybrid entities.

The Ministry has framed the decision as supporting the consistent application of the GloBE Rules and reinforcing the UAE’s commitment to international tax transparency. That framing is consistent with the broader direction of UAE tax policy over the past three years, which has moved steadily from a near-zero-tax environment toward a rules-based system that aligns with OECD standards while still preserving competitive features, such as the continued availability of free zone incentives for qualifying income. The rules apply to fiscal years beginning on or after January 1, 2025, which means groups with a UAE presence should already be assessing whether they, or one of their UAE constituent entities, joint ventures, or reverse hybrid structures, fall within the scope of this filing requirement.

Practical Steps for Businesses Operating in the UAE

Multinational groups with UAE operations should treat this decision as a prompt to review their entity mapping. The first step is identifying every UAE-based Constituent Entity, Joint Venture, Joint Venture Subsidiary, and any Stateless Constituent Entity that might qualify as a Reverse Hybrid Entity under UAE law. The second step is deciding on a filing approach, either each entity filing independently or channelling submissions through a single Designated Local Entity. Groups that already use a centralised compliance function for country-by-country reporting or other Pillar Two obligations elsewhere are likely to find the Designated Local Entity route the more efficient choice.

It is also worth noting what the decision does not do. It does not introduce a new tax, and it does not change the substantive top-up tax calculation methodology established under Cabinet Decision No. 142 of 2024. Its purpose is procedural: to remove ambiguity around filing responsibility so that both the Federal Tax Authority and multinational groups are working from a shared, precise understanding of who reports what.

How My Taxman Can Help

Navigating a filing obligation that touches Pillar Two, joint venture structures, and reverse hybrid entities all at once is not something most in-house finance teams want to handle without specialist support, and this is exactly where My Taxman comes in. My Taxman works with multinational groups operating in the UAE to map out their full entity structure against the new Ministerial Decision No. 133 of 2026 requirements, identifying precisely which UAE constituent entities, joint ventures, and subsidiaries carry a Pillar Two Information Return obligation. The team helps businesses decide whether direct filing or a centralised Designated Local Entity approach makes more sense for their group, and then manages the actual preparation and submission process with the Federal Tax Authority.

Beyond the immediate filing requirement, My Taxman also supports groups with the wider compliance picture that now surrounds multinational operations in the UAE, including corporate tax registration, transfer pricing documentation, and Domestic Minimum Top-Up Tax assessments. For a multinational business trying to stay ahead of a fast-evolving UAE tax landscape, having a dedicated advisory partner that already understands the nuances of Pillar Two, GloBE Rules, and FTA filing mechanics can make the difference between smooth compliance and last-minute scrambling. Businesses uncertain about their filing obligations under the new decision are encouraged to reach out to My Taxman for a structured review of their UAE entity footprint well ahead of upcoming deadlines.
