The OECD’s Base Erosion and Profit Shifting (BEPS) Project is an initiative aimed at reducing double non-taxation arising in the context of cross-border transactions. In October 2015, the OECD published reports on 15 separate action items to address BEPS (BEPS reports). G20 leaders endorsed the BEPS reports in November 2015. Although the BEPS reports are said to be final and to represent a consensus, several of the BEPS reports set out areas of follow-up work, and often countries may choose from several options. This expert Q&A with Eric Wang and Andrew Thomson of Sullivan & Cromwell LLP discusses the key action items addressed in the BEPS reports.
