Pillar Two in the UAE

The phrase "two pillars" comes from the OECD/G20 Inclusive Framework's package on the taxation of the digitalised economy. Pillar One is about where the largest groups are taxed — reallocating a slice of residual profit to the markets where customers are, which requires a multilateral instrument between states. Pillar Two is about how little they can be taxed anywhere: a set of model rules, the Global Anti-Base Erosion or GloBE rules, that push the effective tax rate on a group's profits in every jurisdiction up to a 15% floor.

Only the second pillar has a UAE statute behind it. The Ministry of Finance describes the UAE Domestic Minimum Top-up Tax as "closely aligned with the GloBE Model Rules, Administrative Guidance and Commentary issued by the OECD" and frames it as the UAE's step in implementing the Two-Pillar Solution. There is no UAE Pillar One legislation to read, because Pillar One does not work through domestic law alone.

The practical translation for a UAE finance team: Pillar Two is a rate floor, not a new base. It does not change what is taxable income under the Corporate Tax Law. It measures the tax you actually paid on a separate accounting-based measure of profit, and charges the shortfall.

Article 1.1.1 of the annexure to Cabinet Decision No. 142 of 2024 sets one gateway test. The rules apply to Constituent Entities that are members of an MNE Group whose Ultimate Parent Entity reported annual revenue of EUR 750 million or more in its Consolidated Financial Statements in at least two of the four fiscal years immediately preceding the tested year. Where one of those years was shorter or longer than 12 months, Article 1.1.2 scales the threshold proportionally.

An MNE Group, under Article 1.2.1, is a group with at least one entity or permanent establishment outside the jurisdiction of its ultimate parent. A purely UAE group, however large, is outside these rules. Article 1.3 makes each entity in the group — and each permanent establishment, treated separately from its main entity — a Constituent Entity, unless it is an Excluded Entity: governmental entities, international organisations, non-profits, pension funds, and investment funds or real estate investment vehicles that are ultimate parents.

Two further exclusions matter in practice. Article 2.3 puts an Investment Entity located in the UAE outside the charge altogether. And Article 9.3 reduces the top-up tax to zero during a group's initial phase of international activity — constituent entities in no more than six jurisdictions, and net book value of tangible assets outside the reference jurisdiction not exceeding EUR 50 million — provided no UAE entity is owned by a parent subject to a Qualified IIR elsewhere.

The GloBE model rules offer a jurisdiction three levers: a Qualified Domestic Minimum Top-up Tax that collects the shortfall at home, an Income Inclusion Rule that lets a parent jurisdiction collect the shortfall on foreign subsidiaries, and an Undertaxed Profits Rule as a backstop. The UAE has enacted only the first.

The Ministry of Finance states the position plainly: "As the UAE corporate tax regime does not include a controlled foreign company regime, at this stage, the decision has been made to not implement the Income Inclusion Rule (IIR)." The reasoning it gives is defensive rather than expansionary — the DMTT "protects the UAE's domestic tax base by preventing foreign jurisdictions from collecting top-up tax on UAE profits". The Ministry adds that it will keep the question of an IIR under review.

The legislative chain is short. Article 3(3) of Federal Decree-Law No. 47 of 2022 — a clause inserted by Federal Decree-Law No. 60 of 2023 — directs the Cabinet to issue a decision imposing top-up tax on multinational enterprises "so that the total percentage of the effective tax rate imposed on them is (15%) fifteen percent". Cabinet Decision No. 142 of 2024 is that decision, issued 31 December 2024 and effective from 1 January 2025, with all the operative rules in an annexure. FTA Decision No. 12 of 2026 then sets the registration and deregistration timelines.

The calculation is jurisdictional, not entity by entity. Article 5.1.1 divides the sum of the Adjusted Covered Taxes of every Constituent Entity located in the UAE by the Net Pillar Two Income of the UAE — the aggregate of Pillar Two Income less Pillar Two Losses of those entities, computed under Article 3 from financial accounts rather than from taxable income. That fraction is the group's UAE Effective Tax Rate.

Article 5.2.1 then subtracts it from the Minimum Rate, which the decision defines as "fifteen percent (15%)". The positive difference is the Top-up Tax Percentage. It is not applied to all the profit: Article 5.2.2 first strips out a Substance-based Income Exclusion, so only the Excess Profit is charged.

That exclusion is the reason a genuinely operating UAE business paying 9% corporate tax often has little or no top-up to pay, while a light-substance holding structure has a lot. Article 5.3.3 gives a payroll carve-out of 5% of eligible payroll costs for eligible employees performing activities in the UAE, and Article 5.3.4 a tangible asset carve-out of 5% of the carrying value of eligible tangible assets located here. Both percentages are transitionally higher, tapering under the Article 9.2 tables.

Registration is a duty under Article 13.1 of the annexure, and FTA Decision No. 12 of 2026 supplies the clock. Article 2(1) of that Decision gives an in-scope entity seven months from the end of the first fiscal year in which it is in scope to submit a top-up tax registration application. Article 2(2) overrides that for early years: an entity whose fiscal year ended before 30 April 2026 must apply on or before 30 November 2026.

Deregistration runs on a different clock. Article 3(1) allows six months from the earlier of ceasing to exist or the end of the fiscal year in which the entity leaves the MNE Group and falls out of scope; Article 3(2) sets 31 December 2026 for entities that ceased to exist before 30 June 2026. Article 3(3) blocks deregistration until every top-up tax and penalty is settled and every Top-up Tax Return and Pillar Two Information Return is filed.

Article 4 adds a notification layer that is easy to miss. A group that drops out of scope files an out-of-scope notification within six months of the end of the tested fiscal year; it stays valid for that year and the next four; and if the group comes back into scope, an in-scope notification is due within seven months. Where a Domestic Designated Filing Entity has been appointed under Article 2.2 of the annexure, Article 5 lets it file all of this for every member of the domestic group.

Two mechanisms can reduce the UAE top-up tax to zero without a full GloBE computation, and both are elections rather than defaults.

The Transitional CBCR Safe Harbour in Article 8.2.1.1 deems the UAE jurisdictional top-up tax to be zero for a fiscal year if any one of three tests is met on the group's Qualified Country-by-Country Report: total UAE revenue below EUR 10 million and profit before income tax below EUR 1 million; a Simplified Effective Tax Rate at or above the Transition Rate; or UAE profit before income tax no greater than the substance-based income exclusion amount. Article 8.2.1(n) fixes the Transition Rate at 16% for fiscal years beginning in 2025 and 17% for those beginning in 2026. The Transition Period itself covers fiscal years beginning before 1 January 2027 and ending before 1 July 2028.

The Simplified Calculations Safe Harbour in Article 8.2.2 offers a routine profits test, a de minimis test (average UAE Pillar Two revenue under EUR 10 million and average Pillar Two income under EUR 1 million or a loss) and an effective tax rate test set at 15%.

Article 14.3 is the provision worth putting in front of a board. For fiscal years beginning on or before 31 December 2026, but not including a fiscal year ending after 30 June 2028, no penalties or sanctions apply in connection with filing a Top-up Tax Return or a Pillar Two Information Return where the FTA considers the group took reasonable measures to apply the decision correctly. It is relief from penalties for getting the computation wrong in good faith. It is not relief from registering, filing or paying.

Pillar Two in the UAE is a young regime and parts of the machinery are still being built. Three things we deliberately do not state on this page.

Whether your entity must file a Pillar Two Information Return. Article 15.1 of the annexure makes that obligation depend on entities "specified in a decision of the Minister", with the conditions and procedures set in that decision. Article 15.4 sets the filing date at no later than 15 months after the end of the reporting fiscal year, but the population of filers is defined elsewhere. We could not locate a published Ministerial Decision under Article 15.1 when we checked the Federal Tax Authority's legislation index on 21 August 2026, and we will not assume you are a filer or that you are not one. Note that Article 3(3) of FTA Decision No. 12 of 2026 makes deregistration conditional on those returns being filed, so the question has consequences.

Whether the UAE DMTT holds Qualified status. The Ministry of Finance describes a transitional qualification mechanism run by the OECD Inclusive Framework and says the UAE "is expected to achieve the 'Qualified' status". Expected is not confirmed. Qualified status is recorded centrally by the Inclusive Framework, not by the UAE, and we have not read that central record — so we do not repeat the claim as fact.

Which portal to register through. FTA Decision No. 12 of 2026 requires an application "to the Authority" and does not name a channel; Article 13.1 of the annexure leaves the form and manner to the FTA. Corporate tax and VAT registration run through EmaraTax, and it is reasonable to expect the same, but until the FTA publishes the service card for top-up tax registration we will not tell you where to click.
