Robert Stack joins Deloitte’s national tax office

Robert Stack, former deputy assistant secretary for international tax affairs at the US Treasury, has joined Deloitte, the firm announced June 20.

Stack will join as a managing director of Deloitte in its Washington National Tax, international tax practice.

During his tenure at Treasury, Stack was an outspoken advocate for US interests, particularly with respect to the OECD/G20 base erosion and profit shifting (BEPS) project. He was a sharp critic of other countries’ initiatives aimed at increasing taxation to US multinationals, such as the UK’s diverted profits tax and the EU State aid investigations.

Stack has been involved in all aspects of US international tax policy, including tax treaties, regulations, and legislative proposals.

“I look forward to working with our clients to analyze and respond to the complicated tax, risk, and compliance issues they face,” said Stack. “Tax has become a significant strategic business issue, with initiatives like the OECD’s BEPS project fundamentally changing the global tax landscape.”

Steve Kimble, chairman and CEO of Deloitte Tax LLP said that Stack has extensive international tax experience which will benefit the firm and its clients.

“His experience in the global tax policy arena, along with his tax technical talent, dedication to serving clients, and devotion to growing the next generation of talent, will contribute greatly to the value we provide organizations and our people,” Kimble said.
