Gary R. Huffman Partner, Tax

Gary’s practice focuses on domestic and international tax planning, with a particular emphasis on partnerships, financial products, and natural resources. For more than 30 years, Gary has advised major multinationals, including some of the world’s largest banks, and oil and gas exploration and production companies, on both “inbound” and “outbound” transactions. He adds to the firm's depth of experience in oil and gas taxation, as well as in the structuring of, and raising capital for, master limited partnerships (MLPs). Gary also has led major corporate acquisitions, dispositions, and spin-off transactions, and has structured countless strategic alliances and joint ventures, both domestic and international.

Gary co-authored the treatise Federal Taxation of Partnerships and Partners, (Warren, Gorham & Lamont, 4th edition, copyright 2007). He is an adjunct professor in the Georgetown University Graduate Tax Program, where he has taught advanced partnership taxation for more than 15 years. A frequent lecturer on complex tax partnership issues, Gary is a regular speaker with the Practicing Law Institute, and has addressed audiences at the National Institute of Tax Professionals, the Tax Executives Institute, the Texas Federal Tax Institute, and the Southern Federal Tax Institute.
