Kostelanetz & Fink, LLP has built a national reputation as the law firm of choice for clients facing high-stakes negotiations and controversies with government agencies.  Our attorneys have unparalleled experience in tax controversies, white collar defense and regulatory matters, and as a result handle the most challenging, complex and sensitive cases.  An important part of the firm’s practice includes tax and estate planning and representation in government procurement and government contracting.

In 2018, we were honored as Tax Team of the Year by Chambers USA. The award highlights our strength in the tax controversy sphere and highly regarded work on criminal tax cases, as well as our expansion to a new office with top-level talent in Washington, D.C.


We are skilled attorneys who approach each matter strategically — based on decades of litigation experience. Our partners are regularly sought out as teachers and lecturers and we literally wrote the book on civil and criminal tax controversies. 

Our attorneys have served as former senior leaders of the Internal Revenue Service, the United States Department of Justice and other prosecutors’ offices.  Several of our attorneys have masters’ degrees in taxation and/or have served as federal judicial law clerks.


Our personalized attention to each client is unparalleled.  Our clients, large and small, have immediate access to our partners and to our 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, the firm has the depth and flexibility to add attorney strength as the needs of the client or matter demand.


Kostelanetz & Fink, LLP is well known for its creative strategies and tenacious advocacy and has enjoyed extraordinary success achieving favorable results for clients.
