George Matthew Gerachis

George Matthew Gerachis Partner, Tax

George serves as the Head of the Tax and Executive Compensation and Benefits (ECB) department. He represents corporate and individual clients in a wide range of tax planning and tax controversy matters. Over his 32-year career with the firm, George has assisted numerous individuals, partnerships, and multinational corporations in structuring complex transactions, and in resolving disputes with the Internal Revenue Service. He also is a member of Vinson & Elkins' Management committee.

George takes an interdisciplinary approach to his clients’ matters. In his tax planning practice, he works closely with the client’s tax executives and in-house counsel, as well as financial and operating personnel, external auditors, and various consultants. He focuses on emerging issues at the intersection of tax law and other legal disciplines, such as intellectual property law. Drawing on his extensive experience resolving tax controversies, George brings a unique perspective to the structuring and documentation of transactions.

In his tax controversy practice, George seeks to find practical, cost-effective resolutions to his clients’ issues, keeping in mind the long-term implications of each dispute. While many matters can be resolved at the audit or IRS Appeals level, where such resolution is not possible, George is comfortable in the courtroom, having tried cases in the United States Tax Court and Federal District Courts, and handled numerous appeals.
