IRS Notice 972CG: Penalties, Reasonable Cause, and Response

If you’ve received IRS Notice 972CG, the IRS is proposing civil penalties against your business for problems with information returns you filed — Forms 1099, W-2, ACA forms, and the like. Nothing has been assessed yet. You have 45 days from the notice date (60 if you’re a foreign filer) to respond with corrections, a reasonable cause explanation, or both. Miss that window and the IRS treats the proposed amount as final and bills you.1Internal Revenue Service. Information Return Penalties

Most businesses that respond on time with proper documentation can reduce or eliminate the penalty. The work is in doing it correctly.

What Triggered Your Notice and What It Will Cost

Notice 972CG is the IRS’s formal proposal of penalties under Internal Revenue Code Section 6721, which covers failures to file correct information returns. A parallel penalty under Section 6722 covers failures to furnish correct statements to payees.1Internal Revenue Service. Information Return Penalties

The most common triggers are missing or incorrect Taxpayer Identification Numbers, late submissions, and returns filed using the wrong method or format. One trigger that catches smaller businesses by surprise: any filer with 10 or more information returns in a calendar year must file electronically. That threshold is aggregated across almost all return types, so five 1099-NECs plus five W-2s puts you over the line. Paper-filing when e-filing was required is treated as filing with an incorrect method and produces Section 6721 penalties.2Internal Revenue Service. Who Must File Information Returns Electronically

Each penalty is assessed per return, which is why totals climb fast. An employer who filed 500 W-2s with missing TINs is looking at 500 separate penalties.

Per-Return Amounts for Returns Due in 2026

The amount depends on how quickly the error is corrected after the original filing deadline:1Internal Revenue Service. Information Return Penalties

  • Corrected within 30 days: $60 per return
  • Corrected after 30 days but by August 1: $130 per return
  • Corrected after August 1 or never filed: $340 per return
  • Intentional disregard: $680 per return, with no annual cap

    • ul>

    Annual caps apply except in intentional disregard cases, and smaller businesses (average annual gross receipts of $5 million or less over the three most recent tax years) get lower caps than larger filers.3Office of the Law Revision Counsel. 26 USC 6721 – Failure to File Correct Information Returns

    Exceptions That May Remove Some Penalties Automatically

    Before drafting a reasonable cause letter, check whether any flagged returns qualify for two statutory exceptions. These are not arguments you make; they apply by law when the facts fit.

    The de minimis correction exception treats a return as filed correctly if it contained incomplete or incorrect information but was corrected by August 1 of the year it was due. The exception is limited to the greater of 10 returns or one-half of one percent of the total returns you filed that year.3Office of the Law Revision Counsel. 26 USC 6721 – Failure to File Correct Information Returns

    The small dollar safe harbor covers returns whose only error is an incorrect dollar amount. If no single amount is off by more than $100 (or more than $25 for tax withholding amounts), no correction is required and no penalty applies. A payee can elect out, but unless they do, the safe harbor protects you.3Office of the Law Revision Counsel. 26 USC 6721 – Failure to File Correct Information Returns

    Diagnosing Each Flagged Return

    Notice 972CG arrives with an attachment listing every return the IRS flagged. Cross-reference that list against your original filing records and identify the specific failure on each one: data entry error, TIN never collected, missed deadline, formatting problem, wrong filing method. The evidence you need depends on the type of failure, so the diagnosis drives everything that follows.

    For missing or incorrect TIN penalties, the IRS has specific expectations laid out in Publication 1586. Your response needs to show you completed the required solicitations: an initial solicitation when the account was opened, then up to two annual follow-up solicitations if the first attempt didn’t produce a correct TIN. Each annual mailed solicitation must include a letter warning the payee that failure to provide a TIN may result in penalties, a Form W-9, and a return envelope.4Internal Revenue Service. Publication 1586 – Reasonable Cause Regulations and Requirements for Missing and Incorrect Name/TINs on Information Returns

    For late filings or format errors, document the cause. System outages, vendor failures, natural disasters, and IRS processing errors can all support relief. Gather that evidence before you start writing.

    Building a Reasonable Cause Argument

    Reasonable cause is the legal standard for getting these penalties waived. You have to establish two things, and one alone is not enough. First, the failure resulted from significant mitigating factors or events beyond your control. Second, you acted in a responsible manner both before and after the failure.5eCFR. 26 CFR 301.6724-1 – Reasonable Cause

    Significant Mitigating Factors

    Your compliance history counts. If you’ve never had to file this type of return before, or you have a clean record on prior filings, that helps. The IRS looks at whether you’ve been penalized for the same type of failure previously and whether your error rate is trending down.5eCFR. 26 CFR 301.6724-1 – Reasonable Cause

    Events Beyond Your Control

    This covers situations where the cause was external. Unavailability of business records due to a disaster, undue economic hardship tied to the filing method, and actions by the IRS itself that contributed to the problem all qualify. A software vendor crash on the deadline, a fire that destroyed payroll records, and conflicting IRS guidance are typical examples.

    Acting Responsibly

    This is where most arguments succeed or fail. Even with a legitimate obstacle, the IRS will deny relief if you didn’t take reasonable steps to comply beforehand and to correct the problem afterward. For TIN penalties, that means showing your solicitation history. For late filings, it means showing you filed as soon as the obstacle cleared. Sitting on the problem for months after a system failure sinks an otherwise valid argument.

    What to Put in Your Response and How to Send It

    The response letter is the central document. It has to explain your position, request abatement, and be signed under penalties of perjury. For corporations, the signer must be a president, vice president, treasurer, chief accounting officer, or another authorized officer. For partnerships, any partner can sign.6Internal Revenue Service. 4.19.25 Information Return Penalty (IRP) Procedures

    Include with the letter:

    • The tear-off response page from Notice 972CG, with the appropriate agreement or disagreement section completed and signed
    • A copy of the full Notice 972CG you received
    • Supporting documentation: corrected returns, W-9 solicitation letters, backup withholding records, system failure logs, or whatever else supports the reasonable cause claim

    Send copies, never originals. Mail the package to the address printed on your notice — typically a dedicated IRS service center — using Certified Mail with Return Receipt Requested, or an IRS-designated private delivery service from DHL, FedEx, or UPS. The return receipt is your proof that you met the 45-day deadline.1Internal Revenue Service. Information Return Penalties7Internal Revenue Service. Private Delivery Services (PDS)

    If you need more time, submit a written extension request before the 45 days run. The IRS does not guarantee extensions, but asking before the deadline is far better than missing it.

    After You Respond

    Review typically takes several weeks to several months. You will either receive a letter confirming the penalty has been abated (keep it permanently with your tax records) or a rejection letter assessing the full amount.

    If the IRS Rejects the Argument

    You generally have 30 days from the date of the rejection letter to request a conference with the IRS Independent Office of Appeals. The exact deadline will be printed on the rejection letter itself. To be eligible, you must have already submitted a written abatement request and received a formal denial. Send the appeal request with a copy of the rejection letter, your original reasonable cause explanation, and any additional evidence you can add. If Appeals doesn’t resolve it, you retain the right to go to court, though that step rarely makes financial sense for information return penalties unless the amounts are large.8Internal Revenue Service. Penalty Appeal

    If You Owe and Can’t Pay in Full

    The IRS offers installment agreements that let you spread payments. Apply online through your IRS account, by phone, or by submitting Form 9465. Paying something immediately while a plan is set up demonstrates good faith and slows more aggressive collection.9Internal Revenue Service. Payment Plans; Installment Agreements

    Keeping the Next Notice From Coming

    Most 972CG notices trace back to the same handful of process failures: not collecting TINs at the start of a business relationship, not verifying TINs against IRS records before filing, paper-filing when e-filing was required, and missing deadlines because someone assumed the payroll vendor was handling it. Build a W-9 collection step into onboarding, run the IRS’s free TIN matching tool before filing season, and calendar filing deadlines with enough lead time to fix errors before they become penalties.
