Once the top-up tax for the jurisdiction has been calculated, it is then allocated to the constituent entities in the jurisdiction that have net Pillar Two GloBE income (ie not entities that have Pillar Two GloBE losses) so that the charging provisions (ie the income inclusion rule or under-taxed payments rule) can correctly apply.
Note, that if all of the constituent entities in the jurisdiction are wholly owned and the UPE is applying an income inclusion rule, the allocation amongst constituent entities wouldn’t be required given the UPE would simply account for the top-up tax.
Article 5.2.4 of the OECD Model Rules provide that the allocation is based on each relevant constituent entity’s share of the total net Pillar Two GloBE income of the jurisdiction.
Example
In jurisdiction X:
Company A has net Pillar Two GloBE income of 5 million
Company B has net Pillar Two GloBE income of 10 million
Company C has net Pillar Two GloBE income of 20 million
Company D has a net Pillar Two GloBE loss of 5 million
Total jurisdictional top-up tax is 5 million. This is allocated as follows:
Company A = 5 million * 5/35 = 714,286
Company B = 5 million * 10/35 =1,428,571
Company C = 5 million * 20/35 =2,857,143
Company D = 0
On October 5, 2025, Israel published a consultation on a draft law for a domestic minimum tax (intended to be a Qualified Domestic Minimum Top-Up Tax or ‘QDMTT’) from January 1, 2026.
On October 3, 2025, Turkey published the Draft Communique on the Minimum Tax Law, and the Draft GIR, for consultation. Whilst Turkey has enacted its Minimum Tax Law, a lot of the detailed application of the GloBE rules was left to a further Regulation. This Communique therefore provides for the detailed rules for the implementation of the GloBE rules in Turkey.
On September 18, 2025, Croatia opened a consultation on a Draft Bill to amend its Minimum Tax Act. The amendments are primarily to amend the QDMTT accounting standard so that the Croatian QDMTT qualifies for the QDMTT Safe Harbour and to provide for the notification deadline for appointing a designated filing entity.
On September 26, 2025, Hong Kong updated its Pillar 2 guidance to include information on its Pillar 2 Portal, applications for Group Codes and mandatory e-filing of profit tax returns for Pillar 2 groups.
On September 29, 2025, the Federal Ministry of Finance opened a consultation on a Draft Regulation for the implementation of the Minimum Tax Act. This provides for compliance rules for the exchange of the GIR and simplified reporting.
We keep track of all domestic Pillar Two forms issued to date, including links to domestic forms and notices for each relevant jurisdiction.
On September 16, 2025, The Netherlands Cabinet issued a Draft Bill for the Second Amendment to the Minimum Tax Act to implement the December 2023, June 2024 and January 2025 OECD Administrative Guidance (as well as the EU DAC 9 proposals).
Japan has launched its Multinational Enterprise Information Reporting Portal for filing Pillar 2 returns.
