Thomas D. Sykes
A Singular Federal Tax-Dispute Lawyer
In the nation’s industrial, legal, tax, and political power centers, Tom built a singular, premier, large-dollar, 360-degree federal-tax trial and appellate resume. After starting his legal career as a Wisconsin District Attorney and then as a federal prosecutor, Tom began litigating civil tax cases in 1984 in DC for the U.S. Department of Justice’s Tax Division (DOJ). First chaired or directly supervised perhaps 250 tax cases in federal courts across the nation and in the Court of Federal Claims. Over his career, first chaired 15 cases in the federal courts of appeals and tried 25 jury trials; and handled $3bn to $4bn in tax cases overall. Seventeen years total with DOJ, including seven years of DC-based supervisory experience. As a DOJ–Tax Division senior attorney, “chased bad guys” and worked revenue-heavy and highly technical cases involving issues of first impression. Went into private practice in 1998, when he joined a DC tax boutique as a partner, litigating federal tax cases for large insurance companies. In 2002, joined as a partner the Chicago office of the nation’s largest law-firm tax practice, representing and assisting some of the nation’s largest corporations and nonprofits, and some of its wealthiest individuals and families. Led the charge, nationwide, in the successful effort to recover FICA tax for the nation’s 360 teaching hospitals, notching pivotal wins in The University of Chicago Hospitals’ $38mm case in both the trial court and in the Seventh Circuit. Had more teaching-hospital cases pending in court than any other attorney in the nation when the IRS totally conceded for taxable periods before 2Q2005 — a concession leading to FICA tax refunds approaching $2bn. First-chaired a “most unusual” full-concession from DOJ and IRS of a $15mm bet-the-company, prohibited-transaction penalty case the Southeast. In 2010 joined as a shareholder the law firm that is now one of the nation’s largest. Founded own law firm in January 2016 to pursue a $500mm to $600mm federal-tax class action for about 300 nonprofit teaching hospitals (concluded in 2019). Among other accolades (below), Tom is a thirteen-time, peer-selected Illinois Super Lawyer in Tax (top 5%), including 2013-2021. He has been repeatedly selected as one of Illinois’ top 100 high-stakes litigators (all types of cases). Followed spouse’s career to Seattle area in August 2019.
