Gary Wilcox is a partner in Mayer Brown's Washington DC office and a co-leader of the Tax Controversy & Litigation team. Previously, Gary served as a co-leader of PricewaterhouseCoopers' (PwC) US tax controversy practice, and led the tax practice at another international law firm. He also served as the deputy chief counsel of the US Internal Revenue Service (IRS), where he was in charge of approximately 700 attorneys in the Office of Chief Counsel and had primary responsibility within the IRS for developing its positions on technical tax issues and the issuance of regulations and rulings.

Gary's practice focuses on tax controversies and tax planning. He represents multinational corporations in the audit and appeals phases of an IRS dispute as well as in litigation. Gary has particular experience with controversies arising from complex transactions, typically in a cross-border context, such as leveraged distributions and other repatriations, intercompany debt, worthless stock deductions, and cost sharing arrangements. He has litigated significant cases in U.S. Tax Court involving intercompany debt (ScottishPower) and consolidated return issues (Duquesne Light).

Gary also has many years of experience advising clients on structuring mergers, acquisitions and internal reorganizations, and now regularly advises on planning issues arising from the Tax Cuts and Jobs Act.
