Tax Controversy Team of the Year

The Legal 500 US Awards recognized Mayer Brown as Team of the Year for Tax Controversy for the second consecutive year. The award honors the best private practice teams over the past 12 months.

William Schmalzl focuses on tax litigation, corporate tax planning and state tax advice. He represents clients in all stages of tax litigation including audits, administrative proceedings, United States Tax Court, federal district court and courts of appeals and Illinois state courts. The issues he has litigated include I.R.C. § 482, the investment tax credit, research tax credit, sale-leasebacks, foreign tax credits, franchises, patents and other intangibles. William’s undergraduate majors in economics and mathematics have proven invaluable in the preparation of expert reports and in the examination of expert witnesses at trial.  William’s trial experience includes Seagate Technology, National Semiconductor, United Parcels Service, RJR Nabisco, ConEd and Flextronics.

Prior to joining Mayer Brown, William served as a Clerk to the Honorable Robert A. Ainsworth, Jr., of the 5th Circuit Court of Appeals (1977-1978).

Mayer Brown was recently named Tax Controversy Team of the Year for the second consecutive year in the Legal 500 United States Awards. "Mayer Brown is 'among the best' and fields a large team…dedicated exclusively to tax controversy and transfer pricing," said Legal 500 and its sources in the US edition. The firm is “regularly seen in the most high-profile controversy cases before the US Tax Court” and produced “yet another impressive run of work” in 2014.
