McDermott Will & Emery has a leading tax controversy practice with lawyers representing clients on all aspects of federal, state and local, and international tax controversy matters, including Internal Revenue Service audits and appeals, competent authority matters and trial and appellate litigation. We regularly represent some of the world’s largest corporations on complex US, state and local, and international tax issues. Our transfer pricing team is regularly sought by major multinational enterprises to handle controversy matters, including controversy cases that other professional advisors have not been able to resolve. In addition, we represent high net worth individuals and their closely-held companies in income, estate, and gift tax controversies. Most of these tax controversy matters are successfully resolved without litigation. But when administrative settlement is not possible, we have extensive experience representing our clients in tax litigation at the trial and appellate levels, including before the US Supreme Court.

Our tax controversy group includes seasoned tax litigators, former Internal Revenue Service and US Department of Justice attorneys, and judicial clerks. We believe the insights gained from our combined tax litigation and clerking experience enhances our ability to achieve favorable resolutions for our clients.
