Recent Trends in Managing International Corporate Tax Controversies
Bush House, Strand Campus, London

International corporate tax controversies in the areas of Transfer Pricing and Treaty Interpretation are on the rise. Controversy is expected to further increase for MNEs because of increased public disclosures, the complexity associated with the Pillar II project, the uncertainty around the implementation of the Pillar I project as well as the current political environment.
Against this background, the International Tax Law and Policy Research Network (ITLRN) will host on June 4th, 2025, its fourth international tax event in London (United Kingdom) to discuss recent trends in managing International Corporate Tax Controversies. This event follows the successful completion of our research networks past three events which were held in Belgrade (2022), Milan (2023) and Vaduz (2024) respectively.
The purpose of this event is to explore the current and future trends in international corporate tax controversies as well as to deliberate on practical experiences when the various cross border dispute prevention and resolution tools are invoked to settle / resolve disputes.
The event starts with a Q&A session which will address the current US perspective towards taxing MNEs. Thereafter, senior tax administration officials of large emerging markets will discuss the current and future tax audit issues in their respective markets.
Subsequently, in-house tax directors of large MNEs will discuss current (and possible future tax audit issues), challenges in tax audits, in particular, practical issues in invoking cross border dispute settlement mechanisms.
Then, policy makers (representatives from the OECD, EU and UN Sub Committees) will provide us with recent updates on their work with respect to improving the various dispute prevention and resolution tools that could be invoked by MNEs to settle controversies.
Afterwards, the competent authorities / tax administrations/government officials of selected countries will discuss their practical experience in handling bilateral advance pricing arrangements (BAPA), cooperative compliance programs, mutual agreement procedures (MAPs) and arbitration (including investment treaty arbitration) for issues linked mainly to transfer pricing and treaty law.
With respect to the organisation of the event, ITLRN (the founding members which originate from the University ofBelgrade, University Carlos III Madrid, University of Lausanne and members of Practise) has joined forces with Kings College London to organise the event. The event is also supported by the International CFO alliance, Tax Academy of Singapore, Tax Executives Institute, United States Council for International Business and Wolters Kluwer.
The speakers in this event include renowned experts with different backgrounds coming from academia (prominent tax law professors), tax administration/competent authorities, policy making organisations, members of private practice (international corporate tax and transfer pricing partners) and tax directors from different MNEs.
