From Reform to Reality: The Evolution of International Taxation for Large Multinational Enterprises

The Institute of Finance of SGH, in cooperation with Columbus Private (Suisse) SA, invites you to participate in an international conference entitled: “From Reform to Reality: The Evolution of International Taxation for Large Multinational Enterprises.”

The conference is designed as a high-level forum for discussing the evolving landscape of international taxation and the challenges it presents for both businesses and tax administrations.

The first part of the conference focuses on the global minimum tax, offering participants a comprehensive, practice-oriented insight into the implementation status of the OECD Pillar Two rules and their broader implications for domestic tax systems, investment policy, and cross-border business operations. Central to the discussions will be the transition from legislative design to practical application — exploring how tax administrations and multinational enterprises are responding to the new regulatory environment, what challenges arise in day-to-day implementation, and how businesses can adapt to a post-Pillar Two reality while preserving tax certainty and investment competitiveness.

The second part turns to the evolving debate on international tax litigation, examining tax treaty interpretation, transfer pricing, and the Pillar Two framework across both dispute prevention and dispute resolution. Participants will gain hands-on insight into instruments such as APAs and BAPAs, MAP procedures, and arbitration mechanisms, drawing on practical examples and comparative perspectives from multiple jurisdictions.

By bringing together policymakers, international institutions, tax authorities, business representatives, and leading advisers, the conference aims to create a platform for substantive exchange, strategic reflection, and open dialogue on the future of international tax governance.

The conference is organised by the Institute of Finance of SGH Warsaw School of Economics, the Polish-Swiss Chamber of Commerce, and Columbus Private (Suisse) S.A., under the patronage of the Ambassador of the Swiss Confederation to Poland, and supported by the University of Lausanne, with further partners to be announced.
