Here are the three primary qualities that a taxpayer, expecting or involved in a dispute with the IRS or U.S. DOJ tax authorities, should seek out when hiring a tax-dispute lawyer:

A Long Record of First-Chair, Top-Tier Accomplishment — Preferably Forged in the Federal-Court “Crucible” and National in Scope.

Judgment Seasoned by Many Years Representing the IRS. 

Integrity- and Expertise-Based Credibility with IRS and U.S. DOJ Tax Authorities, and with Federal Courts.

And if the tax dispute has possible criminal overtones, a fourth quality is key as well:    Criminal-Tax Experience as a Federal Prosecutor.  

*                       *                      *

Having first-chaired a vast array of complex and mega-dollar civil federal tax cases from coast-to-coast for 40 years at the very highest reaches of the tax profession …

Having represented the IRS during the first half of his tax career, and having represented a plethora of blue-chip corporate, non-profit, and individual taxpayers during the second half …

Having been a federal prosecutor, with criminal-tax experience …

Having written and filed hundreds of legal briefs in court, having tried over 20 cases to a jury verdict, and having argued 15 cases to the federal courts of appeals …

Having been a supervisor with the Tax Division of the U.S. Department of Justice (DOJ) in DC, and having been a Tax partner or shareholder in the Chicago offices of two of the nation’s largest and most prestigious private law firms …

Having practiced for 18 years each in the “tax vortices” of DC and Chicago, first-chairing cases worth $3 to $4 billion — and now, since 2019, located in Redmond/Bellevue, WA

Having received many coveted, formal awards from his lawyer peers in both DC and Chicago …

Having demonstrated a nimble mind and thought leadership by publishing extensively in premier national tax and non-tax publications, across four decades (i.e., 1980s, and 2000s through 2020s) …

Holding a law degree from a Big Ten, first-tier law school … and

Owning a “360-degree” federal tax-dispute resume that is national in stature …
