Tax Cases

Our lawyers represent clients on all aspects of federal tax controversy matters, including IRS audits and appeals, competent authority matters, and trial and appellate litigation. We also are experienced with the alternative dispute resolution options available to taxpayers during the audit and appeals process. We regularly represent some of the world’s largest corporations, often with hundreds of millions of dollars in controversy. Most tax controversy matters are successfully resolved without litigation, but when administrative settlement is not possible, we have extensive experience representing our clients in tax litigation at the trial and appellate levels, including U.S. Supreme Court litigation.
