Join us as we host a six part webcast series, "Navigating in a post-BEPS world". These sessions will provide a comprehensive review of BEPS related developments and associated country action, together with practical implications.

The OECD BEPS project has rapidly moved to the implementation phase, leaving a fundamentally changed landscape in its wake. This new environment requires businesses to re-evaluate their operational and financing structures, identify communications strategies and assess their tax strategy, all with the aim of developing a sustainable tax framework. Now that all key instruments for BEPS implementation have been released by the OECD (the OECD BEPS reports, Transfer Pricing Guidelines and the Multilateral Instrument) and the European Union and countries are legislating and/or providing more clarity on how they will implement measures, businesses have sufficient information to take stock and set a course to move forward.

The first session will give a broad overview of the key BEPS measures and the challenges and opportunities for businesses as they transition to the new environment. Join our senior international tax professionals as they discuss:

  • BEPS implementation: OECD/G20 developments
  • Recent developments in the European Union
  • US and the prospect of international tax reform
  • Asia Pacific perspective

Later sessions will focus on an in depth analysis of key areas. The complete series and topics to be covered is set out below. As you register for this first webcast, you will be offered an opportunity to pre-register for all the remaining webcasts in this series. You can also register for individual webcasts.
