IRS Criminal Investigation (CI) is the IRS's law enforcement arm — armed special agents who investigate tax crimes for criminal referral. If a CI agent contacts you, your case has already been screened and a criminal referral is imminent. Do not speak with the agent without an attorney present. Politely decline the interview, accept business cards, and call counsel immediately.
Most taxpayers never encounter IRS Criminal Investigation. Those who do should understand: by the time a special agent appears, your case has already been reviewed by a Special Agent in Charge, a Strike Force, and often the U.S. Attorney's Office. The investigation is not a fact-finding mission — it is a documentation exercise to prove a case the government already believes exists.
How CI Cases Begin
Most CI cases originate from one of these sources:
- IRS Civil Audit Referral — Revenue Agent identifies fraud indicators and refers to CI;
- Whistleblower Tip — IRS Form 211 reward program; ex-spouses, ex-employees, and ex-partners are common informants;
- Bank Secrecy Act Referrals — large cash transactions, structured deposits, suspicious activity reports;
- Other Federal Investigations — DOJ, FBI, or DEA cases that uncover tax violations;
- Self-Generated Investigations — IRS data mining (return matching, lifestyle audits) and operations like PPP/EIDL fraud sweeps.
How to Identify a CI Special Agent
Special agents are not auditors. They are armed federal law enforcement officers with arrest authority. They will:
- Identify themselves as IRS Criminal Investigation special agents;
- Display badges (gold star with shield);
- Often work in pairs;
- Carry firearms (concealed);
- Hand business cards reading "Special Agent" — NOT "Revenue Agent" or "Revenue Officer."
If you are uncertain, ask: "Are you a special agent with Criminal Investigation?" The answer matters — special agents handle criminal cases; revenue agents handle civil audits.
The "Knock and Talk"
The most common first contact is a "knock and talk" — special agents appear unannounced at your home or business. The agents will:
- Identify themselves and ask for a brief interview;
- Read or paraphrase a non-custodial Miranda-like warning;
- Ask broad questions designed to lock in your story;
- Compare your answers to evidence they already have.
This is not a fishing expedition. The agents have likely already reviewed your bank records, returns, and witness statements. Anything you say can — and will — be used against you.
The correct response: "I'm exercising my right to consult with an attorney before answering any questions. Please leave your business card and I'll have my attorney contact you."
What Happens After the Interview
After contacting witnesses, the special agent prepares a Special Agent's Report (SAR). The SAR is forwarded to:
- CI Group Manager — first-line review;
- Special Agent in Charge (SAC) — second-level review at the field office;
- Department of Justice Tax Division — Washington DC review for non-routine cases;
- U.S. Attorney's Office — final charging decision and grand jury presentation.
The whole process from initial contact to indictment averages 12-24 months. Defense counsel should engage at any point during this window — earlier is better.
Constitutional Rights in CI Investigations
Fifth Amendment
You have the right to remain silent. You can refuse to answer questions, and your silence cannot be used against you in a criminal prosecution. Tell the agent: "I'm exercising my Fifth Amendment right and would like to speak with an attorney."
Fourth Amendment
Searches of your home or business require a warrant — except for areas open to the public. Subpoenas are common in CI cases; warrants are reserved for cases with risk of evidence destruction.
Sixth Amendment
Right to counsel attaches at indictment. But you can — and should — retain counsel earlier. Pre-indictment representation often results in declination.
Right to Counsel — Even Without Custody
You can have an attorney present during any voluntary interview. The agent will tell you the interview is "voluntary" — that does not mean unrepresented.
Common Mistakes
- Talking to the special agent "to clear things up." Innocent people are convicted on minor inconsistencies in their own statements.
- Destroying records after CI contact — this is obstruction under 18 U.S.C. § 1519, a 20-year felony.
- Filing amended returns after CI contact — this can be used to admit prior false returns.
- Hiring a CPA but not an attorney — CPA-client privilege does not apply in criminal cases. Statements to a CPA are discoverable.
- Calling friends and family about the investigation — they can be subpoenaed and forced to testify.
What to Do If You Are Under Investigation or Charged
- Do not speak with IRS Criminal Investigation (CI) agents without an attorney — even informally. Special agents are not auditors; they investigate crimes.
- Do not destroy or alter records — destruction can become obstruction under 18 U.S.C. § 1519 with a 20-year maximum.
- Locate and preserve all bank records, returns, ledgers, emails, and accountant correspondence.
- Discontinue the conduct — but do not amend returns or take corrective action without counsel; both can be used against you.

Frequently Asked Questions
How do I tell the difference between an IRS auditor and a special agent?
Auditors handle civil audits — they have business cards reading "Revenue Agent" and ask for documents and explanations. Special agents handle criminal cases — they identify as "Special Agent, IRS Criminal Investigation" and carry badges. The difference is critical.
Should I speak with the special agent if I have nothing to hide?
No. Innocent people are routinely convicted on minor inconsistencies between their statements and evidence the agent already has. Polite refusal and request for counsel is the only safe response.
What is a Kovel arrangement?
A Kovel arrangement extends attorney-client privilege to your accountant when the accountant is engaged by your attorney to assist in defense. Without Kovel, your CPA can be subpoenaed and required to testify.
How long do CI investigations take?
12-24 months on average from first contact to indictment, though some run longer. Defense counsel can sometimes accelerate or delay depending on case strategy.
Can I avoid prosecution by cooperating?
Sometimes — through Voluntary Disclosure (before contact), pre-indictment proffers (after contact, before charges), or substantial assistance to the government. Cooperation must be coordinated through counsel to avoid waiving privileges.
