Mark Warren, former Treasury official and congressional tax counsel, joins Capitol Tax Partners

Capitol Tax Partners is pleased to announce that Mark Warren is joining the firm as a partner.

Mark is a highly respected tax expert with several decades of experience both in government and the private sector. He brings deep technical expertise and a sophisticated understanding of the tax legislative and regulatory process that will further strengthen the firm’s ability to provide strategic and substantive advice on tax-policy matters before Congress and the Administration.

Mark has a unique resume with government service spanning both ends of Pennsylvania Avenue and both sides of Capitol Hill. He served as Deputy Assistant Secretary for Legislative Affairs in the Bush Administration Treasury Department. During his time on the Hill, Mark served as Chief Tax Counsel to the Senate Finance Committee, where he worked for then-Chairman Chuck Grassley. He also served as Senior Tax Counsel to now-Senate Majority Leader John Thune and previously worked on the House Ways and Means Committee under Chairmen Dave Camp, Paul Ryan, and Kevin Brady, where he focused primarily on tax-reform legislation.

Jon Talisman, Capitol Tax Partners’ co-founder and managing partner, said, “We are thrilled to welcome Mark to our firm. He is one of the most knowledgeable and effective tax counsels in DC, with a rare combination of substantive and strategic expertise, experience, and common sense. Mark has worked at the center of major tax debates for as long as I can remember and will be an extraordinary asset to our clients and our team, helping them navigate complex legislative and regulatory issues.”

Mark earned an LL.M. in taxation from New York University School of Law, a J.D. from Georgetown University Law Center, and a B.S. in business administration from Georgetown University.
