Hungary Includes Transitional CbCR Safe Harbour Amendments in its 2025 Autumn Tax Package
On October 2, 2025, Hungary released the 2025 Autumn Tax Package. This includes some amendments to the operation of the Transitional CbCR Safe Harbour.
Article 2.10 of the February 2023 OECD Administrative Guidance provides more information on the treatment of the US Global Intangible Low-Taxed Income (GILTI) regime.
This is to be treated as a blended CFC Regime for GloBE purposes. Under the GloBE Rules CFC taxes are allocated to the foreign CFC (subject to the push down restriction). The GloBE Commentary doesn’t go into detail on the allocation and just provides that the CFC tax should be allocated to each CFC based on the owner’s share of the underlying income.
However, determining the allocation can be tricky when there is a blended CFC regime.
The December 2023 OECD Administrative Guidance provides additional information on the application of the Blended CFC rules, including:
– where an MNE Group calculates multiple GloBE Jurisdictional ETRs for different types of Entities located in the same jurisdiction (eg a separate GloBE ETR for investment entities or JVs),
– where an MNE Group is not required to calculate an ETR as they claim the Transitional CbCR Safe Harbour or the QDMTT Safe Harbour, or if the De Minimis exclusion applies
– where a Constituent Entity is subject to a Blended CFC Tax Regime on the income of non-GloBE Entities.

On October 15, 2025, Hungary issued the draft Advance QDMTT Tax Declaration (Form 24GLBADO) as well as filing instructions and a draft XML guide.
On October 10, 2025, Belgium issued a Draft Law to amend its Minimum Tax Act. There are a number of technical amendments (which don’t effect the Minimum Tax calculation), the correction of an error in the original text as well as administrative amendments.
On October 3, 2025 Normative Instruction RFB No. 2282, of October 2, 2025 was published in the Official Gazette. This includes amendments to Brazil’s DMT Law for the OECD June 2024 OECD Administrative Guidance and other sundry amendments.
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.
