For 80 years, Kostelanetz LLP has built a global reputation as a law firm of choice for clients facing high-stakes controversies, negotiations with government agencies, and complex domestic and international tax planning decisions. Our attorneys have extensive experience in tax controversy, tax fraud defense, white-collar criminal defense, trust and estate planning, transactional tax planning, and government investigations. We are regularly called upon to handle the most challenging and sensitive matters and internal investigations. Important parts of the firm’s practice also include commercial litigation and government procurement and contracting.
Kostelanetz attorneys are highly skilled and approach each matter strategically based on decades of administrative and litigation experience and as advisors on domestic and international tax compliance issues. Many of our attorneys have served as former senior officials within the Internal Revenue Service, the U.S. Department of Justice, the Securities and Exchange Commission, 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.
The firm and its attorneys have been honored and recognized by major, independent national and international legal rankings agencies, including Chambers USA, The Legal 500, Best Lawyers, and Super Lawyers.
Kostelanetz LLP attorneys are thought leaders who frequently write articles for The CPA Journal, Tax Notes, The Journal of Tax Practice & Procedure, Law360, and other respected publications on the latest topics and trends in tax law, civil and criminal tax enforcement, transactional tax planning, estate and trust planning, commercial litigation, and white-collar criminal defense & government investigations, including recent developments in IRS audits, IRS criminal investigations, state and local enforcement actions against alleged tax evasion, and enforcement measures taken by the Justice Department, the SEC, FinCEN, and various government regulatory agencies.
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.
