Fundamentals of the Global Minimum Tax
As more than 50 jurisdictions move forward with the implementation of the OECD/G20 Inclusive Framework’s Pillar Two Global Minimum Tax (GMT), the international tax landscape is undergoing one of the most significant transformations in decades. Countries are introducing the GloBE rules and the Qualified Domestic Minimum Top-up Tax (QDMTT), confronting complex policy design choices while navigating continuous interpretative developments. At the same time, multinational enterprises and tax administrations must apply highly technical, interconnected, and fast‑evolving rules—further shaped by the latest Administrative Guidance and recent political milestones, such as the Side‑by‑Side Package agreed by the United States and the G7.
This three‑day fundamentals course is designed to give participants a clear, structured and practice‑oriented introduction to the GMT framework. It is ideal for professionals new to Pillar Two, as well as those looking to consolidate their foundational knowledge before advancing to higher‑level technical analysis. The programme blends conceptual explanations, walkthroughs of rule mechanics, practical examples, and interactive discussions to build confidence and understanding across all core elements of the GloBE rules.
