Where and how to report suspected tax evasion

You can report suspected tax evasion to the Internal Revenue Service using Form 211, also called the process for Award for Original Information. This is the official channel the IRS uses to receive reports from the public. You submit it to the IRS Criminal Investigation division, which is separate from the regular tax audit process.

You can also report through the IRS website at www.irs.gov/form211, where you'll find the form itself and instructions. The form asks you to describe what you know about the suspected evasion, including the person's or business's name, address, and the specific tax years involved. You don't need to have proof — the IRS investigates based on what you report.

If you prefer not to use the form, you can mail a written statement to the IRS Criminal Investigation office in your region, or call the IRS Criminal Investigation hotline at 1-800-366-4484. The hotline is available Monday through Friday, 8 a.m. to 4:30 p.m. Eastern time. You can remain anonymous through any of these methods.

Key Takeaways

  • Form 211 is the official IRS document for reporting suspected tax evasion, and you can submit it online, by mail, or by phone.
  • You do not need evidence or documentation to file a report — describe what you know and let the IRS investigate.
  • The IRS Criminal Investigation division handles these reports separately from routine audits.
  • You can report anonymously and will not be identified to the person or business you report.
  • If the IRS pursues the case and recovers taxes, you may be awarded a percentage of what is recovered, though awards are not may provide.

What information to include in your report

Form 211 asks for the name and address of the person or business you're reporting, along with their Social Security number or Employer Identification Number if you have it. You should also provide the tax years you believe are involved in the evasion. The more specific you can be, the easier it is for the IRS to investigate.

Describe what you observed or learned that led you to suspect evasion. This might be that someone reported significantly lower income than you know they earned, claimed deductions you believe are false, or failed to report income from a particular source. You can describe conversations you overheard, documents you saw, or patterns you noticed. The IRS will decide whether the information warrants investigation.

If you have documents — bank statements, emails, receipts, or other records — you can attach them to your report. However, do not send originals; send copies only. The IRS will not return documents you submit, and originals could be needed if the case goes to court.

The difference between reporting and whistleblower awards

Reporting suspected tax evasion and pursuing a whistleblower award are related but separate processes. When you file Form 211, you're giving the IRS information. If they investigate and recover taxes as a result of your report, you may be awarded money — typically between 15 and 30 percent of the amount recovered, though the IRS has discretion on the exact percentage.

However, awards are not may provide. The IRS awards money only when the case results in a recovery of more than $2 million. If the IRS investigates but finds no violation, or if the violation is minor, you will not receive an award. You also will not receive an award if the IRS was already investigating the person or business before your report.

If you are reporting because you work for the person or business and have direct knowledge of their tax practices, you may have additional protections under whistleblower laws. These protections prevent retaliation by your employer, but they explore only in specific situations. The IRS can explain whether your situation qualifies.

How the IRS investigates after you report

After you submit Form 211, the IRS Criminal Investigation division reviews your report to decide whether it warrants investigation. This review can take weeks or months. You will not receive updates on the status of the investigation, and the IRS will not tell you whether they opened a case based on your report.

If the IRS decides to investigate, they may contact the person or business directly, subpoena records, interview people who know them, or examine bank accounts and financial records. The investigation is confidential — the IRS does not disclose who reported the suspected evasion.

If the investigation finds evidence of evasion, the IRS may pursue criminal charges through the Department of Justice, or they may pursue a civil penalty without criminal prosecution. Civil penalties are more common and result in the person or business owing back taxes, interest, and a penalty. Criminal prosecution is reserved for cases involving deliberate, large-scale evasion.

What happens if you report someone you know

Reporting a family member, friend, or colleague can be difficult, but the IRS keeps your identity confidential. The person or business you report will not be told who reported them. If the IRS contacts them, they will only know that a report was made.

You should be aware that if you report someone and the case becomes public — through news coverage or court documents — people may be able to figure out who reported based on who had access to the information. The IRS's confidentiality protects your identity from the agency's side, but it does not prevent others from deducing it.

If you are reporting your employer or a coworker and fear retaliation, you have additional protections under federal whistleblower laws. These laws prohibit employers from firing, demoting, or otherwise punishing you for reporting tax violations. You can file a complaint with the Occupational Safety and Health Administration (OSHA) if you believe you've faced retaliation.

When to report versus when not to

You should report if you have specific knowledge that someone has not reported income, claimed false deductions, or otherwise violated tax law. "Specific knowledge" means you have direct information — you saw documents, heard them describe their practices, or worked with their finances — not suspicion based on their lifestyle or spending.

You should not report based on assumptions. For example, if someone appears to have money but you don't know their income source, or if they claim deductions you think are unusual but you don't know the details, reporting may waste the IRS's time and resources. The IRS investigates thousands of reports each year and prioritizes those with concrete information.

If you are unsure whether what you know constitutes evasion, you can contact the IRS Criminal Investigation office before filing Form 211. They can discuss your situation and advise whether a report is warranted. This conversation is also confidential.

How long the process takes and what to expect

The timeline from report to resolution varies widely. The IRS may take months or years to investigate, and if they pursue criminal charges, the case may take additional years to move through the court system. You will not receive updates during this time.

If the IRS recovers money and you are awarded a percentage, the award is typically paid after the recovery is final — meaning after any appeals are resolved and the money is actually collected. This can be years after your initial report. The IRS will contact you if you are awarded money, using the contact information you provided on Form 211.

Awards are paid by check from the U.S. Treasury. The amount is subject to federal income tax, so you will receive a Form 1099 for the award amount. You must report the award as income on your tax return for the year you receive it.

Frequently Asked Questions

Can I report someone anonymously?

Yes. You can submit Form 211 without providing your name or contact information, though doing so means the IRS cannot contact you if they need clarification or if you become may have access to to an award. Most people who report do provide contact information so they can receive an award if one is issued.

What if I'm not sure if what I know is actually tax evasion?

You can call the IRS Criminal Investigation hotline at 1-800-366-4484 and describe the situation without filing a formal report. The IRS can tell you whether what you're describing sounds like evasion. If you're still unsure after that conversation, you can decide whether to file Form 211.

Will the person I report find out it was me?

The IRS will not tell them. However, if the case becomes public or goes to court, documents may become available that could help them figure out who reported them. The IRS's confidentiality protects you from the agency's side only.

Do I need a lawyer to report tax evasion?

No. Form 211 is straightforward and you can complete it yourself. A lawyer is not necessary unless you are reporting your employer and are concerned about retaliation, in which case a lawyer can advise you on your whistleblower protections.

What if the IRS doesn't investigate or doesn't find anything?

The IRS receives many reports and investigates those with the strongest information first. If they don't investigate your report, or if they investigate and find no violation, you will not receive an award. You also will not be told why the case was closed or whether it was investigated at all.
