Overview

The EY law tax practice team has an extensive technical understanding of all tax types, including customs duties, and specialises in handling complex cross-border tax issues, BEPS matters and MAPs. The indirect tax practice team consists of professionals with specialist skills in technology and data management, and also has a strong legislative background. Tori Sullivan is the key tax partner in the team. 

Sullivan and the team recently represented Anderson & O’Leary in a tax dispute. They represented the client in the initial independent review stage and the District and High Court, alongside Jenny Cooper QC in the High Court. The dispute is still ongoing, and the team will be representing the client in the Court of Appeal in 2023. 

Senior Associate Jonathan Choie left for EY Singapore during the research period.
