The Act on Top-up Taxation of Constituent Entities of International and Domestic Groups (hereinafter: the Act), i.e. groups that have achieved annual consolidated revenues of at least EUR 750 million in at least two of the four tax years preceding the examined tax year, entered into force on January 1, 2025.
The provisions allow taxpayers to voluntarily apply the Act already to the tax year beginning after December 31, 2023, i.e. in principle already for 2024 (the group’s decision to opt for this solution may be made between March 1, 2026, and May 30, 2026).
The purpose of the Act is to implement into the Polish tax system the top-up taxation provided for in Council Directive (EU) 2022/2523 of December 14, 2022, under which enterprises with consolidated accounting revenues equal to or exceeding EUR 750 million in at least two of the four tax years preceding the examined tax year will be required to pay a top-up tax if their effective tax rate (ETR), calculated under the new rules, is lower than 15%.

The Act provides for measures aimed at reducing the burdens associated with the application of the new provisions, intended to simplify procedures.
These measures, referred to as safe harbours, may be either permanent or temporary.

the so-called safe harbour for the Qualified Domestic Minimum Top-up Tax (QDMTT safe harbour),
safe harbour for constituent entities with low material financial results,
safe harbours applicable during the initial period of a group’s activity,
temporary CbCR safe harbour.


Particular attention, in the initial period of being subject to top-up tax obligations, should be paid to the temporary CbCR safe harbour.
In the first step, taxpayers should identify the obligations imposed by the Act and whether they can apply the CbCR safe harbour.
