Federal excise taxes imposed on goods, services, and activities contributed $98.5 billion to U.S. government revenues in 2019. The IRS pursues the collection of these taxes aggressively and taxpayers need counsel with a deep knowledge of federal excise tax practices and procedures to ensure they do not overpay them. As a leading tax practice in the U.S. according to Chambers USA, we have an unsurpassed track record of success in solving our clients' most complex excise tax challenges.

Our lawyers have an in-depth understanding of the byzantine federal excise tax regimes. And we understand the internal policies and personalities within the IRS office responsible for administering federal excise taxes. We assist clients with the intricacies of collecting, reporting, and paying federal excise taxes in compliance with IRS rules. In addition, we regularly guide clients through the process of obtaining refunds of overpaid excise tax. This process is often arcane, counter-intuitive, and complex with many millions of dollars at stake. When administrative relief is unavailable, we stand ready to pursue refund claims in court. We have litigated and won federal excise tax cases in a variety of jurisdictions. Our seasoned team has a long track record of achieving significant excise tax relief for our clients, having navigated many groundbreaking controversies resulting in the aggregate reduction of tax burden of hundreds of millions of dollars.

Although we help clients reduce their excise tax burdens across many industries, our lawyers are particularly experienced with the excise taxes imposed on fuel producers and other manufacturers, and the excise taxes imposed on air travel. We have unparalleled experience in these subfields and have led the way in some of the largest controversies over the past few years.
