IRS Criminal Investigations Explained
For most people, the first sign that the IRS is looking at them criminally comes without warning. Two Special Agents from the IRS Criminal Investigation Division (IRS-CI) may show up at your home or business, introduce themselves, and begin asking questions. It’s rarely a mere casual visit—if IRS-CI knocks on your door, the Service may suspect some wrongdoing.
How do I know if the IRS is Investigating Me?
For many people, the first sign is a visit from IRS-CI agents. Other red flags include:
Receiving an IRS summons for testimony or records.
Your accountant, bank, employer, employee, or client telling you that the IRS contacted them about you or a product that you sell.
Getting unusual letters from the IRS requesting interviews or documents.
How IRS Criminal Investigations Begin
IRS criminal investigations often start internally as administrative investigations. Special Agents may:
Visit you in person, usually in pairs (one to ask questions, the other to take notes)
Serve you with an IRS summons seeking records or testimony for certain tax years
Request to interview you about your tax filings or financial transactions.
At this stage, the investigation is still with the IRS. But it can escalate. If IRS-CI develops evidence suggesting criminal tax violations, the matter may be referred to the Department of Justice (DOJ) for further investigation and potentially prosecution.
From IRS Investigation to DOJ Referral
Once the case is in DOJ’s hands, prosecutors can use the full power of the federal grand jury. The grand jury can:
Subpoena records from banks, accountants, and other third parties
Compel testimony under oath
Return formal charges (an indictment)
At this stage, the stakes rise dramatically.
Unlike the IRS summons process, a grand jury subpoena carries contempt power—refusal can mean jail.
The Grand Jury: Risk and Opportunity
While a grand jury often signals that charges are likely, it doesn’t always spell bad news. In some cases, the government may use the grand jury to grant immunity to certain witnesses. Immunity may protect individuals from prosecution in some instances in exchange for testimony, cooperation, and waiver of Fifth Amendment rights.
This is a critical difference:
IRS administrative investigations cannot offer immunity.
DOJ grand jury investigations can—but only in certain circumstances.
Does Every IRS Criminal Investigation Lead to Charges?
No. Not every IRS investigation results in prosecution. Some cases close if the evidence isn’t strong or if defense counsel intervenes early to present facts or narrow the scope. And sometimes, defense counsel may be able to resolve issues without referral to DOJ.
If You Believe the IRS is Looking at You Criminally, Take a Breather and Contact Counsel
An IRS knock on the door is not routine. It’s often the first step in a process that can end up in federal charges. But the stage of the case matters:
At the IRS administrative stage, defense counsel may be able to prevent the case from escalating to DOJ.
At the DOJ stage, defense counsel may help you understand your options, incliuding any Fifth Amendement rights and opportunities to negotiate with the prosecutor.
Either way, the most important step is the same: contact an experienced criminal tax lawyer immediatley. Early intervention can make the difference between indictment, immunity, or no case at all.
