White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
An IRS criminal investigation is not a routine tax dispute. It is a high-stakes federal matter that can threaten your financial security, professional standing, and personal freedom. When the Internal Revenue Service escalates a case to its criminal arm, the consequences are immediate and serious.
At Chapman, Dowling & Mallek, we represent executives, professionals, and business owners facing investigations led by the IRS Criminal Investigation Division (IRS-CI). These investigations often involve allegations of tax evasion, fraud, and complex financial crimes. Early, strategic legal intervention is essential—not only to protect your rights, but to control the trajectory of the case before irreversible damage occurs.
From a legal standpoint, IRS criminal investigation defense is a highly specialized discipline that combines sophisticated tax knowledge with elite federal criminal defense. It is not reactive—it is strategic, proactive, and precise.
Effective representation typically includes:
IRS-CI investigations are typically built around allegations of willful misconduct. Common examples include:
Criminal tax cases are investigated by IRS-CI Special Agents—federal law enforcement officers with broad investigative powers. These agents can execute search warrants, issue subpoenas, and conduct in-depth financial investigations.
IRS-CI frequently works alongside other federal agencies and ultimately refers cases to the U.S. Department of Justice Tax Division. Federal prosecutors—not the IRS—make the final decision on whether charges are filed.
The penalties associated with IRS criminal cases are severe and often life-altering. Depending on the allegations and financial exposure, consequences may include:

Quiet. Strategic. Decisive.
Every federal case is built long before the courtroom—and often ends before it ever reaches one. Led by a former federal prosecutor and U.S. Marine Corps Judge Advocate—supported by former federal investigators—our process is designed to resolve matters quietly, strategically, and with precision.
We engage early, often before formal charges are filed. By understanding how federal agencies build cases, we work to shape the investigation, limit exposure, and control the narrative from the start.
Our credibility and insight into federal procedure allow us to communicate effectively with prosecutors and investigators—often achieving resolution through dialogue rather than litigation.
We combine investigative experience with advanced data analytics and AI to uncover patterns, test government theories, and identify weaknesses in complex financial, digital, or regulatory evidence.
Whether through negotiation or trial, our approach is tailored to secure the best outcome — quietly, strategically, and decisively, with every step focused on protecting our clients’ reputations and results.
