Michel Sanchez O’Sullivan is an international tax partner at KPMG, where he leads the firm’s Mexico Desk based in New York City. He advises global asset managers and multinational groups on the tax aspects of cross-border investments and operations between the United States and Mexico, with a particular focus on structuring, implementation and ongoing tax management of complex transactions.

With over 15 years of experience, Michel counsels private equity, energy and infrastructure, and other alternative asset managers on some of the most significant and innovative deals in the Mexican market. His practice encompasses fund formation and downstream structuring, acquisition and disposition planning, joint ventures, co-investment arrangements, refinancing and exit strategies. He regularly advises on the use of Mexican investment vehicles, cross-border holding and financing structures, and the interaction of Mexican, U.S. and treaty provisions.

Michel also works closely with multinational corporate clients across a range of industries on inbound and outbound investments, supply chain and business model restructurings, financing arrangements and strategic acquisitions. He has extensive experience managing complex, multi-jurisdictional projects and coordinating advice for clients with significant operations in Mexico and Latin America.

He holds a Mexican law degree and an MBA from Columbia Business School, both awarded with honors. At Columbia, Michel concentrated in private equity and alternative investments, strengthening his ability to bridge legal, tax and commercial considerations in advising sponsors and institutional investors.

Prior to joining KPMG, Michel spent over 12 years at top-tier law firms, including Creel, García-Cuéllar, Aiza y Enríquez, S.C., and international law firm Garrigues, where he developed a sophisticated transactional tax practice and deep experience working with international clients and leading financial institutions.
