Mauritius issues Detailed QDMTT Regulations
On August 8, 2026, Mauritius issued its QDMTT regulations to implement its QDMTT.
Tax transparency is a feature of many domestic tax regimes as a means of applying a single layer of taxation. Tax transparent entities are also used by MNEs for a variety of tax (and non-tax) reasons, not least the ability to maximize double tax relief.
A key feature of the GloBE rules is to try and reflect key features of domestic tax regimes, particularly in the calculation of GloBE income. As such, in many cases, a tax transparent entity would be treated for Pillar Two purposes in the same way as it is for domestic tax purposes, subject to some specific GloBE adjustments (eg to reflect income of non-group members or permanent establishments).
However, where the tax transparent entity is itself the Ultimate Parent Entity (UPE) of the group, this poses some problems in the application of the GloBE Rules.
Income can’t be allocated to the owners, as they would not be within the scope of the Pillar Two GloBE rules. In addition, tax paid by the UPE may be minimal given tax is payable on the income by its owners. This could lead to very low effective tax rates for a tax transparent UPE and substantial top-up tax obligations.
Therefore, the Model Rules include a number of special rules to deal with these situations.
Under the Model GloBE Rules, a flow-through entity is either a tax transparent entity or a reverse hybrid entity.
These three carve outs can be useful for UPEs.
The GloBE income reduction for natural persons, for instance, recognises that whilst identifying the tax position of minority owners may be difficult for a UPE, individuals are generally not subject to special tax regimes for income from a tax transparent entity.
As such, it is reasonable not to require the UPE to determine the tax position of a natural person that holds an ownership interest of less than 5% of the profits or assets of the UPE. This means that a UPE would be required to identify the tax position of no more than 19 individuals.
