Global minimum taxation
(Pillar 2): Current context, developments and implications

Global minimum taxation, also known as Pillar 2, is a major international tax reform project that aims to subject companies to an effective tax rate of 15% regardless of their country of residence. Pillar 2 affects internationally active companies with a turnover of at least EUR 750 million.

In Germany, the minimum tax law has been in force since January 1, 2024, meaning that German companies must now take measures to comply with the new requirements.

Current context

Pillar 2 remains a key topic of discussion on both the national and international political stage. In the meantime, the US prepared tax “countermeasures” against countries that have implemented Pillar 2 in order to prevent potential tax burdens for US corporations. Section 899 of the “One Big Beautiful Bill Act” which became known as the “revenge tax” was essentially averted through joint consultation and a statement by the G7 countries at the summit in Canada. However, the political debate continues, as it remains to be clarified how US companies will be treated in the Pillar 2 context and how the agreement reached at the G7 summit will be implemented in legislation.

In Germany, the draft bill for the law to amend the Minimum Tax Act and implement further measures (Minimum Tax Amendment Act – MinStAnpG) has now been published. Following two discussion drafts from last year, this is now the third draft of the long-awaited law, which again contains significant changes.

Possible implications for German companies

The draft MinStAnpG (MinStAnpG-E) published on August 6, 2025, contains individual measures in the Foreign Tax Act (AStG) and Income Tax Act (EStG) as well as comprehensive amendments to the Minimum Tax Act (MinStG). The following proposed amendments are particularly relevant for internationally active family businesses and corporations:

In previous drafts of the MinStAnpG, the reporting packages used for consolidation purposes (known in practice as “reporting packages”) were already intended to serve as a qualified data basis for, among other things, the calculation of transitional safe harbor provisions (Section 87 (2) sentence 2 no. 1 MinStG-E). This provision remains part of the MinStAnpG and thus represents an extremely relevant simplification for companies. In addition, reporting packages are now also to be used as a data basis for the purposes of Section 82 (1) sentence 1 MinStG-E and thus for the full calculation (Full GlobE calculation) in the first year of application.

The newly created provisions to prevent abuse pursuant to Sections 82 et seq. MinStG-E represent a significant change to the drafts under discussion. The introduction serves to implement the OECD administrative guideline on Pillar 2 published on January 15, 2025, and is intended to prevent circumvention of the minimum tax, in particular through government measures and regulations that enable the capitalization of deferred taxes. The new regulations further increase the complexity of applying the MinStG.

Section 274 (1) sentence 2 HGB provides for an option to capitalize deferred taxes. The amendment to Section 50 (1) sentence 2 no. 3 half-sentence 2 MinStG-E is intended to enable the recognition of an asset surplus for Pillar 2 purposes that is not recognized as deferred tax assets under Section 274 HGB or a comparable foreign regulation. This is expressly to be welcomed. However, it is questionable whether the current wording achieves the legislator's intention; this is only made clear in the explanatory memorandum to the law. It is to be hoped that the final version of the law will provide clarification in this regard.

In addition, the new regulation does not cover all cases of unrecognized deferred taxes for the purposes of calculating the minimum tax. This applies, for example, to cases under Section 274a No. 4 HGB, i.e. small corporations within the meaning of the HGB that are exempt from the application of Section 274 HGB. As a result, unrecognized deferred tax assets for such companies could continue to be disregarded for minimum tax purposes.

The introduction of the MinStG results in an overlapping scope of application with the license barrier pursuant to Section 4j EStG. Previously, the license barrier was intended to prevent German business expense deductions in the case of preferential taxation at a rate of 15% on license income from foreign license creditors. This provision is being repealed. The measure is to be welcomed in view of the reduction in bureaucracy and simplification of tax legislation.

On the other hand, the repeal of Section 4i EStG, which was still included in the second discussion draft, is no longer planned. Section 4i EStG is intended to prevent double deduction of operating expenses in cases where expenses are deducted both abroad as operating expenses and in Germany as special operating expenses. The explanatory memorandum to the second draft bill correctly pointed out that the introduction of Section 4k EStG means that Section 4i EStG is no longer necessary. It is not clear why the legislature has departed from this view. In the interests of simplifying tax legislation, the final MinStAnpG should again provide for the repeal of Section 4i EStG.

Sections 8 et seq. of the AStG regulate German additional taxation for low-taxed subsidiaries that generate so-called passive income. Section 9 AStG in its current version provides for an exemption limit of 10% and EUR 80,000 of total income for mixed income (i.e. both active and passive income), with the result that passive income is disregarded if it falls below this limit. This exemption limit is to be increased to one third and EUR 100,000.

Classification of the draft bill on the MinStAnpG

The long-awaited MinStAnpG provides for welcome changes to the MinStG, which will contribute to less complex application. In particular, the consideration of reporting packages for both transitional safe harbor calculations and full GloBE calculations represents a simplification. Unfortunately, simplifications are not being created across the board, as requested in the comments on the discussion drafts. Rather, the new anti-abuse provisions, for example, further increase the complexity of applying the MinStG.

As expected, the MinStAnpG does not contain any statements on permanent safe harbor regulations. These are urgently needed in view of the currently applicable transitional safe harbor regulations, which are limited until 2027. It would be desirable for the legislator to respond promptly to the permanent safe harbor regulations already discussed at the OECD level and to implement them.

In conclusion, it should be noted that global minimum taxation remains high on the political agenda and is not expected to be abandoned. Companies should therefore address this issue in order to be well prepared, particularly for the annual financial statement process and the upcoming initial tax return obligations on June 30, 2026.
