Speaker Bio
From January 2021 through January 2023, Itai Grinberg was the Deputy Assistant Secretary (Multilateral Negotiations) in the Office of Tax Policy of the United States Department of the Treasury. In that role he was the lead US delegate and negotiator for all OECD and Inclusive Framework matters, including with respect to Pillar 1 and Pillar 2, and questions related to taxation and climate change. He also spoke for the U.S. Treasury with respect to international tax questions across the whole of the foreign policy apparatus of the government of the United States. Finally, he regularly contributed to G7 and G20 efforts of the US Department of the Treasury, traveled with Secretary Yellen to G7 and G20 meetings, and functioned as the link between the offices of Tax Policy and International Affairs at the U.S. Treasury.
Prior to his time as Deputy Assistant Secretary, Mr. Grinberg was a Professor of Law at Georgetown. His academic research focused on fundamental tax reform and international tax policy, as well as the intersection of international tax law, international trade law, international investment law, and international financial regulation. As an academic, Mr. Grinberg testified repeatedly before the US Congress and the German Bundestag on international tax matters, and acted as an outside international tax expert for the Organisation for Economic Co-operation and Development, the Asian Development Bank, and the Inter-American Development Bank. During his time at Georgetown he also maintained a private sector consulting practice.
Before joining the Georgetown University faculty, Mr Grinberg was on the staff of the Office of the International Tax Counsel at the U.S. Department of the Treasury. In his first tour at the U.S. Treasury, he represented the United States on tax matters in multilateral settings, negotiated tax treaties with foreign sovereigns, had responsibility for a wide-ranging group of cross-border tax regulations, and represented the United States on many issues at the OECD. He was the lead US delegate who worked to re-establish the Global Forum on Transparency and Exchange of Information for Tax Purposes and convert it into a peer review body. He also played a key role in the development of FATCA and the CRS.
Earlier in his career, Prof. Grinberg practiced law in the tax group at Skadden, Arps, Slate, Meagher & Flom LLP, and served as Counsel to the President's Advisory Panel on Federal Tax Reform, a bipartisan advisory commission appointed by President Bush that proposed fundamental tax reforms for the United States.
