On 24 September 2026, the Chamber of Tax Advisors of the Czech Republic (KDP ČR) delivered its formal commentary to the Ministry of Finance on the proposed amendment to the Top-Up Tax Act (zákon o dorovnávacích daních). This amendment represents the Czech Republic’s next step in implementing the OECD/G20 Inclusive Framework’s Pillar Two Global Anti-Base Erosion (GloBE) Rules, which establish a 15% global minimum corporate tax for multinational enterprise groups with annual revenues exceeding EUR 750 million. The Chamber’s submission includes detailed observations on the draft law’s scope, computational mechanics for the qualified domestic minimum top-up tax (QDMTT), the income inclusion rule (IIR), and the undertaxed profits rule (UTPR). The comments also address transitional safe harbors, filing obligations, and the interaction with existing Czech corporate income tax provisions. The Ministry is expected to incorporate stakeholder feedback before the bill proceeds to parliamentary debate, with an anticipated effective date for fiscal years beginning on or after 31 December 2026. Multinational groups with Czech operations must assess the impact on their effective tax rates and prepare for enhanced reporting requirements.
Key Takeaways
- Pillar Two Transposition: The amendment codifies the EU Directive 2022/2523 into Czech law, introducing QDMTT, IIR, and UTPR mechanisms with specific local adaptations for holding structures and investment funds.
- Compliance Burden Mitigation: KDP ČR advocates for simplified reporting for groups with no low-taxed constituents, alignment of data points with Country-by-Country Reporting, and clear guidance on the application of the substance-based income exclusion.
- Strategic Tax Planning Impact: Affected groups should model the top-up tax liability under the new rules, review entity classification elections, and evaluate the feasibility of restructuring to optimize the effective tax rate within the GloBE framework.
