FTA Announces Top-up Tax Guide on Scope and Registration Ahead of the 30 November Registration Deadline
The UAE’s Federal Tax Authority (FTA) has clarified the country’s Domestic Minimum Top-up Tax (DMTT) rules, giving multinational groups clearer direction ahead of a key registration deadline. In its official announcement on 7 October 2026, the FTA explained which entities fall within the regime, who must register and when applications are due.
The announcement comes as multinational businesses prepare for the UAE’s global minimum tax requirements under OECD Pillar Two. For groups assessing Pillar Two and top-up tax obligations in the UAE, the guidance offers practical direction on registration and compliance.
FTA Formally Announces TTGREG1, the Top-up Tax Guide on Scope and Registration
The FTA’s latest announcement highlights its guidance on the UAE’s Qualified Domestic Minimum Top-up Tax (QDMTT). It gives multinational groups a clearer framework for assessing whether their UAE operations fall within the legislation and identifying the entities responsible for registration.
The Guide's Issue Date and Legal Basis
The FTA’s Top-up Tax Guide on Scope and Registration (TTGREG1) was issued in August 2026 and highlighted in the Authority’s October announcement.
It explains the application of Cabinet Decision No. 142 of 2024, which introduced the UAE’s top-up tax framework for fiscal years beginning on or after 1 January 2025.
The legislation follows the OECD’s Global Anti-Base Erosion (GloBE) rules, which seek to establish a minimum effective tax rate of 15% for large multinational groups.
The Topics the Guide Covers
TTGREG1 addresses revenue thresholds, constituent entities, permanent establishments, joint ventures, flow-through entities and hybrid structures.
It also explains registration procedures, applicable deadlines and the treatment of entities whose calculated Top-up Tax is zero.
Through practical examples, the guide helps finance and tax teams assess their obligations across different group structures.
The EUR 750 Million Threshold and the Groups Outside Scope
The UAE DMTT regime targets large multinational enterprise groups rather than businesses generally. Its application depends primarily on consolidated group revenue and whether the group operates across national borders.
The Two-of-Four-Years Revenue Test
Under the UAE Top-up Tax framework, an MNE group generally falls within scope when its consolidated annual revenue reaches EUR 750 million or more in at least two of the four fiscal years preceding the relevant year.
The threshold is determined using the consolidated financial statements of the Ultimate Parent Entity, not the standalone revenue of UAE subsidiaries.
Groups must also consider specific rules for mergers, demergers and fiscal years shorter or longer than 12 months when determining their eligibility.
Groups Operating Only in the UAE Fall Outside Scope
The FTA confirms that groups operating exclusively within the UAE are outside the QDMTT regime, regardless of revenue.
However, qualifying multinational groups with UAE operations must assess the status of their constituent entities.
Importantly, the 15% minimum tax for multinationals does not represent a general increase in the UAE’s standard Corporate Tax rate.
Top-up Tax Registration Stands Apart From Corporate Tax Registration
One of TTGREG1’s key clarifications is that DMTT registration is a separate compliance obligation. Existing UAE Corporate Tax registration does not automatically satisfy top-up tax registration requirements.
Entities subject to the charging provisions must register through EmaraTax, individually or through an appointed Domestic Designated Filing Entity (DDFE).
The 30 November 2026 Deadline and the Seven-Month Rule
Under FTA Decision No. 12 of 2026, entities whose first in-scope fiscal year ended before 30 April 2026 must submit their DMTT registration applications by 30 November 2026.
For other entities, the deadline is seven months after the end of their first in-scope fiscal year.
The November deadline is therefore a transitional requirement rather than a universal deadline for every multinational group.
Businesses should confirm the registration deadline applicable to each relevant entity based on its fiscal year.
Registration Applies Even Where Top-up Tax Is Zero
A zero tax liability does not necessarily remove the registration requirement.
Under TTGREG1, entities covered by the charging provisions must register even where their Top-up Tax is deemed zero under certain safe harbours.
However, Excluded Entities and qualifying Investment Entities outside the charging provisions generally do not need to register, subject to applicable elections.
This makes entity-level classification essential for accurate DMTT registration in the UAE.
The AED 10,000 Late-Registration Penalty Applies to Each Entity
Failure to register within the prescribed deadline attracts an administrative penalty of AED 10,000 per entity.
Where a DDFE fails to submit applications for multiple entities, the penalty applies separately to each entity whose registration deadline is missed.
Groups should therefore verify their entity registers, registration status and filing responsibilities before the applicable deadline.
The Pillar Two Information Return and the Companion Guide on Excluded Entities
Registration is only one part of UAE Pillar Two compliance. Relevant entities must also consider their obligations to submit the GloBE Information Return, known locally as the Pillar Two Information Return.
On 25 August 2026, the Ministry of Finance announced Ministerial Decision No. 133 of 2026, establishing filing requirements for UAE constituent entities, certain joint ventures, their subsidiaries and qualifying reverse hybrid entities.
The return may be filed directly by the relevant entity or through a Designated Local Entity, subject to applicable conditions.
The FTA also published Guide TTGEIE1 on Excluded Entities and Investment Entities, explaining the treatment of government entities, non-profit organisations, pension funds and qualifying investment structures.
These classifications influence whether an entity falls within the QDMTT charging provisions.
The UAE's QDMTT Status Within the OECD Pillar Two Framework
The UAE’s QDMTT operates within the OECD’s global minimum tax framework, preserving the country’s primary taxing rights over qualifying domestic profits.
The FTA confirmed that the UAE received transitional qualified status in the OECD central record on 18 August 2025.
For multinational groups, deferred tax and Pillar Two accounting considerations remain important alongside registration and reporting obligations.
Conclusion
The FTA’s latest guide provides multinational groups with clearer direction as the 30 November 2026 transitional registration deadline approaches.
Businesses should verify consolidated revenue, review their UAE group structures and identify entities requiring registration. They must also distinguish DMTT obligations from existing Corporate Tax registrations and assess their Pillar Two Information Return responsibilities.
Early preparation can help avoid administrative penalties while supporting consistent tax reporting across jurisdictions.
