ZeroSync Accountants helps UAE multinational groups build the data, calculations, controls and filing process needed for Pillar Two and the UAE Domestic Minimum Top-up Tax.
Best for UAE-headquartered MNEs, subsidiaries of large groups, regional finance teams and groups preparing for GloBE calculations and DMTT compliance.
Pillar Two is the global minimum tax framework for large multinational enterprise groups. It tests whether each jurisdiction where the group operates is taxed at an effective rate of at least 15% under the GloBE rules.
The UAE Domestic Minimum Top-up Tax is one local part of that framework. Pillar Two compliance is wider than the DMTT alone because it includes data, calculations, safe harbour testing, controls and coordination with the global group filing position.
Pillar Two should be treated as a finance and tax process. The biggest challenge is usually data readiness, not the headline 15% rate.
Review DMTT Page| Scope area | What applies | ZeroSync review point |
|---|---|---|
| Group type | Multinational enterprise group with cross-border constituent entities. | Map UAE entities, foreign entities and permanent establishments. |
| Revenue threshold | EUR 750 million or more in consolidated revenue. | Confirm group revenue across the relevant lookback years. |
| Lookback period | At least two of the four preceding financial years. | Check which financial years count and whether figures are consistent. |
| UAE start date | UAE DMTT applies for financial years starting on or after 1 January 2025. | Build a timeline around the first affected period. |
| Groups near threshold | Not automatically in scope, but should monitor growth and deals. | Review acquisitions, disposals and revenue trends. |
Confirm whether the group is in scope and identify all UAE constituent entities, branches and reporting responsibilities.
Identify whether finance systems can produce constituent-entity income, covered taxes, asset and payroll data.
Calculate jurisdictional income, covered taxes, effective tax rate and potential top-up tax.
Assess whether transitional safe harbours reduce calculation work for the UAE or other jurisdictions.
Connect the UAE domestic top-up tax position with the global Pillar Two calculations.
Build review steps, documentation and timelines so filings can be supported.
Most groups need more than a tax calculation. They need a data process that finance teams can repeat every year.
| Area | Pillar Two compliance programme | UAE DMTT |
|---|---|---|
| Scope | Group-wide global framework for minimum tax. | UAE domestic top-up tax for UAE profits. |
| Main purpose | Test jurisdictional effective tax rates and coordinate global reporting. | Collect UAE top-up tax where the UAE ETR is below 15%. |
| Data requirement | Group-wide constituent-entity data across jurisdictions. | UAE data that aligns with group GloBE calculations. |
| Owner | Often group tax, finance and headquarters team. | UAE finance or tax team, coordinated with the group. |
| ZeroSync role | Support the UAE component, data readiness and local calculations. | Scope, model and prepare the UAE top-up tax position. |
Practical view: For UAE groups, the DMTT may be the most immediate local obligation, but it cannot be handled properly without Pillar Two data and calculations.
The headline rule is simple: a 15% minimum effective tax rate. The operational reality is more detailed. The GloBE rules use their own concepts of income, tax, adjustments, entity location and jurisdictional blending.
Groups often discover that the required data is split across ERP systems, local ledgers, consolidation files, payroll records, fixed asset registers and tax workpapers.
| Complexity | Impact |
|---|---|
| GloBE adjustments | Accounting profit may need multiple adjustments. |
| Covered taxes | Current and deferred tax treatment must be mapped carefully. |
| Jurisdictional blending | The UAE result may interact with group-level calculations. |
| Safe harbours | Eligibility can reduce work but must be documented. |
| Data ownership | Tax, finance and reporting teams need clear roles. |
Transitional safe harbours can reduce the calculation burden for qualifying jurisdictions in the early years. They do not remove the need to analyse the position. The group must test the conditions, keep evidence and ensure the conclusion aligns with CbCR and financial data.
ZeroSync assesses whether the UAE position could qualify and whether relying on a safe harbour is practical, defensible and consistent with the group approach.
A safe harbour can save time, but an unsupported safe-harbour claim can create risk. We treat it as a documented position, not a shortcut.

Pillar Two is the OECD global minimum tax framework for large multinational groups. It uses GloBE rules to test each jurisdiction's effective tax rate against a 15% minimum.
MNE groups generally fall in scope if they have consolidated revenue of EUR 750 million or more in at least two of the four preceding financial years.
Pillar Two is the global framework. The DMTT is the UAE domestic top-up tax within that framework.
The rules require detailed jurisdictional data, GloBE adjustments, covered tax analysis, substance-based carve-out calculations, safe harbour testing and coordination across group entities.
Data readiness. Many groups do not yet capture constituent-entity financial and tax data in the format required for GloBE calculations and jurisdictional reporting.
As early as possible. The UAE DMTT applies from financial years starting on or after 1 January 2025, and data collection, systems and group coordination take time.
Potentially. Transitional safe harbours can reduce calculation work for a qualifying jurisdiction, but eligibility must be tested and documented carefully.
Yes. ZeroSync can support the UAE component of a group Pillar Two programme and coordinate with headquarters, finance teams and external advisors.
