Brazil Implements the SBTI Safe Harbour
On 18 September 2026, Brazil issued IN RFB No. 2,342/2026 to introduce a new framework for the treatment of substance-based tax incentives under its Pillar Two rules.
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.

On 15 September 2026, the Dutch government presented a bill that would introduce four new Pillar Two safe harbours, extend the Transitional Country-by-Country Reporting Safe Harbour and amend the treatment of certain 52- and 53-week accounting periods.

On September 11, 2026, the OECD released a package of guidance and implementation materials that provides for the exclusion of Explicitly Conditional Taxes from Covered Taxes, clarifies the treatment of mismatched fiscal periods under the Qualified Domestic Minimum Top-up Tax Safe Harbour, updates the GloBE Information Return and establishes the detailed framework for full legislative reviews of domestic minimum tax rules.

Uruguay’s presidential decree dated 31 August 2026 replaces the conditional QDMTT payment waiver in Decree No. 325/025 with a compensation mechanism. Article 1 requires in-scope constituent entities allocated QDMTT in Uruguay to comply with its QDMTT obligations and pay the tax; article 7 repeals the earlier decree.

Qatar has published six decisions dealing with currency conversion, simplified reporting, the Transitional CbCR Safe Harbour, non-material constituent entities, designated local entities and registration.

The Slovak Government has approved draft legislation that would make significant changes to Slovakia’s qualified domestic minimum top-up tax regime. The proposals would implement the OECD’s new Substance-Based Tax Incentives Safe Harbour, extend the Transitional CbCR Safe Harbour and introduce rules preserving Pillar Two filing and payment obligations where a Slovak taxpayer ceases to exist without a legal successor.

Cyprus has opened a public consultation on amendments to its Pillar Two legislation intended to address observations from the European Commission and align the domestic rules more closely with OECD guidance. The consultation opened on 30 July 2026 and is scheduled to close on 5 September 2026.
