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.
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.
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:
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.
