IFA 2025 Congress

Overview


McDermott is proud to be a bronze sponsor at the IFA Congress 2025.

IFA Congresses are the most important yearly events in tax matters, gathering experts from around the world and offering them a venue to discuss the latest tax developments.

This year’s Congress will have two exciting Main Topics: “Residence of legal entities for corporate income tax purposes” and the “Improper use of tax treaties from the source state perspective”.

Moreover, and in addition to the IFA signature seminars (IFA/OECD, IFA/EU and recent developments), the congress will have stimulating discussions focusing on topics such as the role of intermediaries in planning, avoidance and evasion, taxation and ESG, transfer pricing and intra-group services, latest developments in Pillar II, and wealth taxation and tax fairness.
