Overview

William B. Sherman advises clients on domestic and international tax planning for mergers and acquisitions, restructurings, joint ventures and investments, helping clients structure transactions that account for tax consequences across jurisdictions. Based in Miami and Fort Lauderdale, he counsels financial and strategic investors across a broad range of industries, including private equity, healthcare, hospitality, petrochemicals, aluminum, real estate, transportation, telecommunications, retailing, investment management and pharmaceuticals.

Cross-border investment is a core part of Bill's practice. He advises on transactions involving U.S. investment overseas and foreign investment in the U.S., addressing the international, federal, state and local tax issues that can determine how a transaction is structured and how it performs.

Beyond cross-border transactions, he counsels clients on the tax aspects of structuring investment management funds, corporate reorganizations, partnerships, equipment leasing, Subchapter S corporations, executive compensation and stock options, as well as trusts and estates. This breadth allows William to align tax planning with a client's broader business and investment objectives.

A well-known lecturer, Bill chairs New York University's Summer Institute in Taxation's Introductory and Advanced International Tax Seminars and its Institute on Federal Taxation International Tax Program. For 12 years, he was an adjunct professor of tax law in the University of Miami Graduate Tax Program, where he taught courses in Taxation of Merger and Acquisitions and Outbound Foreign Tax.

Bill is a past chair of Holland & Knight's Tax Team. He also is past chair of the American Bar Association (ABA) Tax Section Committee on U.S. Activities of Foreigners and Tax Treaties and has served on numerous panels for The Florida Bar, ABA, Southern Federal Tax Institute and others. Bill is admitted to practice in New York and Florida. His teaching and bar leadership reflect his extensive knowledge of tax issues involving mergers and acquisitions and international tax matters, which he applies to clients' transactional and planning needs.
