Irell & Manella LLP’s Tax practice has enjoyed a national reputation since the firm’s founding as a tax boutique more than 75 years ago. Recognized as a leading tax practice by Chambers USA, The Legal 500 and U.S. News Best Law Firms, we are experienced in virtually every aspect of federal, state, local, and international taxation of public and privately owned C and S corporations, as well as partnerships, limited liability companies, and individuals. Our business tax practice includes all aspects of mergers, acquisitions, sales, reorganizations, restructurings, distributions, and financings for both closely held and publicly held businesses. We regularly provide advice regarding:

  • Implementation of tax efficient organizational and investment structures.
  • Tax planning for mergers, acquisitions, sales and other complex transactions.
  • Tax aspects of bankruptcy restructurings and insolvency workouts.
  • Tax planning for ongoing business operations, including equity and debt financings.
  • Audits, appeals proceedings and litigation relating to federal and state tax issues.

Our practice is fairly unique in that our lawyers regularly handle both tax planning for transactions and tax controversy matters. We believe that both aspects of the practice inform the other and make us more creative and sensitive to the potential review of transactions by the taxing authorities, on the one hand, and provide an understanding of the transactional realities when explaining a transaction upon audit. We are frequently tasked with finding creative solutions to seemingly insoluble tax and structural problems.

In addition to the exceptional legal work performed for clients, Irell tax attorneys are active in the tax work of national professional organizations such as the American Bar Association. Many of our attorneys conduct continuing education courses and seminars for attorneys, accountants, and businesspersons and publish articles in prominent tax periodicals. Two of our attorneys, for instance, serve as principal author and contributing author of the bankruptcy tax volume of the Collier Bankruptcy series, which is also published as a separate one-volume treatise on bankruptcy taxation.

Irell attorneys have supported the University of Southern California Tax Institute for decades, serving as founders, chairs, members of the planning committee and speakers. An Irell attorney is a former chair of the Corporate Tax Committee, and two are former chairs of the Affiliated and Related Corporations Committee of the Tax Section of the ABA. Additionally, one of our attorneys has held a significant executive post in the office of the Assistant Secretary for Tax Policy of the U.S. Treasury Department.
