Will Skinner focuses his practice on corporate tax planning and transactions, including mergers and acquisitions, financings, spins, restructurings, partnerships, and licensing matters. Will draws on extensive experience with technology and life sciences transactions to shape tax structures in pursuit of clients’ business goals. Will also provides corporations with standalone tax advice, including formal and informal opinions on technically challenging tax issues in Subchapter C, U.S. international tax and other areas.
During his 20 years in practice, Will has handled dozens of complex, multibillion-dollar transactions, and worked with leading software, fintech, and life sciences companies on their internal tax planning. Willing to cross silos, Will’s reach spans different areas of federal income tax in order to provide clients with effective tax advice. In his recognition from Chambers, one multinational client described Will as a “highly sophisticated professional with a broad tax vision.”
Will is a lifelong resident of the San Francisco Bay Area, having attended both UC Berkeley and Stanford for undergrad and law school, respectively. Before entering private practice, Will clerked for the Honorable Carlos T. Bea on the U.S. Court of Appeals for the Ninth Circuit in San Francisco.
