For more than 75 years, Kostelanetz LLP has built a global reputation as the law firm of choice for clients facing high-stakes controversies and negotiations with government agencies. Our attorneys have unparalleled experience in tax controversies and white-collar criminal defense and are regularly called upon to handle the most challenging and sensitive cases and internal investigations. Important parts of the firm’s practice include tax and estate planning, commercial litigation, government procurement, and government contracting.

Kostelanetz attorneys are highly skilled and approach each matter strategically based on decades of administrative and litigation experience. Many of our attorneys have served as former senior officials within the Internal Revenue Service, the U.S. Department of Justice, and other federal and state prosecutors’ offices. Several of the firm’s attorneys have served as federal judicial law clerks and/or have master’s degrees in taxation.

Kostelanetz attorneys are thought leaders who frequently write articles for The CPA Journal, Tax Notes, The Journal of Tax Practice & Procedure, Law360, and other reputable publications on the latest topics and trends in tax law. Several of our partners teach at top law schools (such as NYU and Georgetown), present CLE/CPE courses on tax-related and legal ethics topics, and are often hired as expert witnesses or consultants in tax controversy litigation.

Our individual and institutional clients have immediate access to the firm’s partners and most senior attorneys. The firm focuses on providing value to its clients and is sensitive to the balance between cost and benefit inherent in every legal assignment. As a result, we have the depth and flexibility to add attorney strength as the needs of the client or matter demand.
