South Korea to Apply a QDMTT from January 1, 2026
South Koreas 2025 Tax Reform Proposal (announced on July 31, 2025), provides that a QDMTT will be applied from January 1, 2026.
Investment entities and investment funds are subject to a number of special provisions under the Article 7 of the Pillar Two GloBE rules.
These in part seek to reconcile the domestic tax treatment of these entities with the GloBE rules and ensure that any impact on the top-up tax calculation does not hinder the application of the GloBE rules.
Note that investment entities are frequently not within the scope of the GloBE rules.
This may be because they are the UPE (see more in our Scope analysis) or it may be because they are less likely to have foreign operations or hold controlling interests in foreign subsidiaries.
Where an investment entity is the UPE of an MNE group it is classed as an excluded entity under Article 1.5.1 of the OECD Model Rules. As such no GloBE ETR, top-up tax or obligation to account for tax via an Income Inclusion Rule (IIR) applies.
Note, however, that the revenue of the excluded investment entity is still taken into account for the purposes of the 750 million euros revenue threshold.
In addition, under most accounting standards an exemption is provided so that the MNE group does not include eligible investment entities in the consolidated financial statements:
• Under IFRS 10 investment entities do not consolidate their subsidiaries. Instead, they are measured at fair value through the profit or loss account.
There are a couple of exceptions to this including:
(1) if the subsidiary provided investment advisory services to the investment entity, and;
(2) if the investment entity is owned by another company (a non-investment entity) then it consolidates all subsidiaries including the investment entities and any entities it controls. Non-controlling interests though wouldn’t be consolidated even by the UPE.
• Under ASC 820 investment companies use the fair value accounting method for non-controlling interests in other investment companies.
Generally, most investment funds hold minority (ie non-controlling) interests in their investments and they would not need to consolidate. As such, they would not be included in the MNE group for GloBE purposes.
Even if an investment entity held controlling interests in other entities and therefore was required to consolidate, if those entities met the requirements to be treated as excluded entities then the group would be outside the scope of the GloBE rules.
It should also be noted that many funds are structured as flow-through entities for tax purposes (eg as an English or Delaware limited partnership). They are still subject to the general requirement to consolidate for controlling interests.
However, in many cases, there would not be an element of control or a requirement to consolidate.
For instance, one of the requirements of consolidation under IFRS 10 is that the investor has the ability to affect the amount of the investor’s returns.
If such an entity was included in the consolidated financial statements, its treatment would be as identified below for a tax transparent investment entity (ie generally its GloBE income would flow up the chain to other constituent entities in the MNE group, after a reduction for amounts due to non-group members).
The general process for calculating top-up tax for investment companies under Article 7.4 of the OECD Model Rules is:
1. The top-up tax percentage is determined by deducting the investment entity ETR from the 15% global minimum rate
2. The MNE groups allocable share of the investment entities GloBE income is reduced by the substance-based income exclusion (‘excess profits’)
3. The top-up tax percentage is applied to the excess profits
As noted above, multiple investment entities in a jurisdiction effectively form a separate investment entity group which is subject to a separate jurisdictional ETR calculation.

On July 24, 2025, the Luxembourg Government issued:
– a draft law to amend its Minimum Tax Law to provide for the January 2025 OECD Administrative Guidance and the EU DAC 9 GIR filing requirements: and
– a draft Regulation which includes the format of the GIR
On July 16, 2025, Kuwait updated its electronic registration portal to include Pillar 2 registration for in-scope groups.
The Pillar Two effective tax rate (ETR) calculation for investment entities is similar to the standard ETR calculation, however, there is an important twist in that the top-up tax is adjusted for minority interests. There is no adjustment for minority interests under the standard ETR calculation. In this article we look at the impact of this.
Foreign tax credits interact with the Pillar Two GloBE Rules in a number of ways. In this article we assess the key impact.
In most cases, a Qualifying Refundable Tax Credit will result in a higher Pillar Two effective tax rate than a non-qualifying tax credit. However, this is not always the case. We look at some examples in this article.
On July 9, 2025, ANAF Order 1.729/2025 was issued to nominate a single designated entity for QDMTT filing and payment purposes, if there are several constituent entities in Romania that are part of the same group.
On June 30, 2025, Japan issued its updated GloBE Information Return (GIR) to reflect the OECD GIR changes in January 2025.
The Executive Regulations were issued on June 29, 2025, in Ministerial Resolution No. 55 of 2025. The Regulations provide for the detailed rules for the application of the domestic minimum top-up tax from January 1, 2025.
