Who Qualifies for an IRS Whistleblower Award?

You may qualify for a monetary award if you provide specific, timely, and credible information about tax noncompliance or violations of laws the IRS enforces that leads to the collection of proceeds (tax, penalties, interest, additions to tax, criminal fines, civil forfeitures, etc.).

Two award programs exist:

  • IRC Section 7623(b) – Mandatory Awards (15–30% of collected proceeds): Requires the action to involve more than $2 million in proceeds in dispute and, for individual taxpayers, gross income exceeding $200,000 in at least one relevant tax year.
  • IRC Section 7623(a) – Discretionary Awards: For claims that do not meet the 7623(b) thresholds.

Ineligible whistleblowers include:

  • Current or former Treasury Department employees who obtained the information in their official duties.
  • Federal employees who learned the information through official duties.
  • Individuals required by law to disclose the information or who obtained it under a federal contract.

The IRS performs a “taint review” to ensure the information is not privileged (e.g., attorney-client) or ethically compromised.

How to Submit a Whistleblower Claim (Form 211) – Updated 2026 Process?

  1. Complete Form 211 – Application for Award for Original Information (download here).
  2. Provide detailed information:
    • Narrative description of the alleged noncompliance.
    • Supporting documents or their location.
    • How and when you learned the information.
    • Your relationship (if any) to the taxpayer.
    • Taxpayer’s name, address, TIN (if known).
  3. Sign under penalty of perjury – A representative cannot sign for you.

Submission options (current as of December 2025):

  • Online (preferred): Secure portal at https://wo.for.irs.gov/s/form211.
  • Mail: Internal Revenue Service, Whistleblower Office – ICE, M/S 4110, 1973 N. Rulon White Blvd., Ogden, UT 84404.

Do not fax or email claims. You will receive a confirmation letter with your claim number. Use the same online form (or mail) to submit additional information later.

Pro tip: Keep a copy of everything. Update your mailing address and phone number immediately with the Whistleblower Office to avoid delays in award payments.

The Whistleblower Claim Process Timeline (From Publication 5251)

Publication 5251 includes a helpful flowchart with approximate timeframes. The entire process can take many years because it depends on IRS examination, appeals, collection, and final tax determinations.

Typical stages:

  • Intake & Initial Review: 30–90 days (rejection/denial or forward for examination).
  • Field Examination/Investigation: 1–3+ years.
  • Appeals or Tax Court (if taxpayer disagrees): 3–10 years.
  • Collection of Proceeds: Up to 10 years (collection statute).
  • Award Evaluation & Payment: 30–90 days after final determination and collection.

Common reasons for initial rejection:

  • Incomplete Form 211
  • No actionable issue
  • Information already public
  • Statute of limitations expired
  • Ineligible whistleblower

The IRS notifies you in writing when your information is referred for examination (does not guarantee an award) and when the taxpayer makes related payments.

How Much Can You Earn? Award Percentages & Payments

Awards range from 15% to 30% of the collected proceeds directly attributable to your information.

  • Higher percentages reward substantial, original contributions.
  • Reductions apply if information came from public sources or you planned/initiated the violation.

Recent results (FY 2024):

  • $123.5 million paid in awards
  • Based on $474.7 million in collected proceeds
  • Third-highest annual award total in program history

Since 2007:

  • Over $1.3 billion paid in more than 2,500 awards
  • Leading to collection of more than $7.37 billion from noncompliant taxpayers

Payments occur only after all appeals are final or you waive appeal rights, and proceeds are actually collected. The IRS issues payments “as promptly as circumstances permit.”

Communicating With the IRS Whistleblower Office

Due to strict confidentiality rules (IRC Section 6103), phone calls receive limited information (open/closed status only).

Written status/stage requests (one per claim per calendar year):

  • Must be mailed to the Ogden address above.
  • Include your claim number(s).
  • Can be submitted by you or your authorized representative via Form 2848.

You will also receive mandatory notifications under the Taxpayer First Act (2019) about referrals for examination and taxpayer payments.

Whistleblower Protections

  • The IRS protects your identity to the fullest extent permitted by law.
  • The U.S. Department of Labor provides anti-retaliation protections against employers.
  • More details: IRS.gov and whistleblowers.gov.

Tips for a Strong Whistleblower Claim

  • Be as specific and detailed as possible — vague tips are rejected.
  • Include all supporting documentation you have.
  • Consult an experienced tax whistleblower attorney before filing (especially for large claims).
  • Do not represent the taxpayer in any IRS matter after filing.
  • Update your contact information promptly.
