I Got a $25,000 Form 5472 Penalty Notice — What Do I Do Now?

If the IRS assessed a $25,000 Form 5472 penalty, you generally have three options: pay it, request abatement in writing on reasonable cause grounds, or appeal. The penalty under IRC § 6038A(d) is assessed automatically by computer, so a reasonable cause letter you already sent may never have been read. Respond in writing by the date on the notice.

The notice usually arrives as a CP215, "Notice of Civil Penalty Charge." It names your LLC, cites a tax year, and shows a $25,000 charge with a short response window. It is frightening precisely because it arrives with no warning and no explanation of what you did wrong.

This guide explains what triggered the penalty, why the letter you may have already written did not stop it, and what an effective response actually contains. If you still have unfiled years alongside the penalized one, we prepare and fax complete Form 5472 packages from $149 — filing the missing years is usually the first step in any abatement request.

Why did the IRS assess a $25,000 Form 5472 penalty?

The IRS assesses a $25,000 penalty when a reporting corporation fails to file Form 5472 when due and in the manner prescribed, or files a substantially incomplete form. The rule is in IRC § 6038A(d) and is restated plainly in the IRS Instructions for Form 5472 (Rev. December 2024): "A penalty of $25,000 will be assessed on any reporting corporation that fails to file Form 5472 when due and in the manner prescribed."

Four separate failures trigger the same $25,000 charge:

1. Not filing at all for a year in which the LLC had a reportable transaction.
2. Filing late — even by one day past the due date, including extensions.
3. Filing substantially incomplete — the instructions state that a substantially incomplete Form 5472 "constitutes a failure to file Form 5472."
4. Failing to maintain records as required by Regulations section 1.6038A-3.

The penalty applies per form, per year. A foreign-owned LLC that missed three years faces $75,000, not $25,000. And if the failure continues for more than 90 days after the IRS notifies you, the instructions provide for an additional $25,000 penalty, with further amounts accruing for continued non-compliance.

Two clarifications that matter for your response letter:

• The penalty is not a tax. It is not calculated from income. An LLC with zero revenue and one $500 capital contribution can owe the full $25,000, because the penalty is charged for the missing information return, not for unpaid tax.
• The penalty is systemically assessed. No human reviewed your file and decided you were culpable. A computer noticed a missing or late return and issued the charge.

Why was my reasonable cause letter ignored?

Because the IRS's own published procedure says it may be. This is the single most misunderstood point in the entire process, and it is why many owners are blindsided by a penalty after doing what they believed was the correct catch-up filing.

The IRS's Delinquent international information return submission procedures page — reviewed 19 April 2026 — states directly: "During the processing of the delinquent information return, penalties may be assessed without considering the attached reasonable cause statement." The page carves out an exception only for Forms 3520 and 3520-A, where reasonable cause statements are considered before a penalty is assessed. Form 5472 has no such carve-out.

In plain terms: attaching a reasonable cause statement to a late Form 5472 does not stop the penalty from being assessed. It preserves your argument for later. The IRS explicitly notes that "it may be necessary for taxpayers to respond to specific correspondence from the IRS and submit or resubmit reasonable cause information."

That correspondence is the CP215 you are holding. It is not proof your statement was rejected on the merits. In most cases it is proof the statement was never read at the assessment stage. Resubmitting it — properly formatted and specifically addressed to the notice — is the intended next step, not a wasted effort.

This is also why practitioners who tell clients "just file late with a reasonable cause letter and you'll be fine" set clients up for exactly this shock. The catch-up filing is correct. The expectation that it prevents assessment is not.

Does First Time Abate apply to a Form 5472 penalty?

No. The IRS's First Time Abate (FTA) administrative waiver covers three penalty types only, and the Form 5472 penalty is not among them.

The IRS Administrative penalty relief page — reviewed 14 July 2026 — lists FTA as available for:

• Failure to file (IRC § 6651(a)(1), § 6698(a)(1), § 6699(a)(1))
• Failure to pay (IRC § 6651(a)(2), § 6651(a)(3))
• Failure to deposit (IRC § 6656)

International information return penalties under IRC § 6038A do not appear on that list. A clean three-year compliance history is helpful context inside a reasonable cause argument, but "this is my first offense" is not, by itself, a basis for relief on a Form 5472 penalty.

The route that does exist is statutory. IRC § 6038A(d)(3) provides that the penalty does not apply where the failure was due to reasonable cause and not willful neglect. That is the standard your letter has to meet.

What counts as reasonable cause for a Form 5472 penalty?

Reasonable cause means you exercised ordinary business care and prudence and still could not comply. The Treasury regulations require an affirmative showing, made under penalties of perjury, of all the facts supporting the claim.

Arguments that carry weight, when true and documented:

Argument	Why it can work	What you must attach
You never knew the obligation existed and no adviser told you	The 2017 extension of § 6038A to disregarded entities is genuinely obscure; many formation agents never mention it	Formation agent's service list, correspondence showing no tax advice was provided
You relied on a professional who got it wrong	Reliance on qualified tax advice is a recognized reasonable cause ground	Engagement letter, the adviser's written advice, proof you disclosed all relevant facts
Serious illness, death, or incapacity of the person responsible	Standard reasonable cause ground	Medical records, death certificate, dates that line up with the filing period
Records were destroyed or unobtainable	Standard reasonable cause ground	Incident reports, insurance claims, bank confirmations
You corrected the failure voluntarily before IRS contact	Demonstrates good faith, not willful neglect	Fax confirmation receipts with timestamps predating the notice

Arguments that consistently fail:

• "The LLC had no income." Irrelevant. Form 5472 reports transactions, not income.
• "The penalty is disproportionate to the size of my business." Real, and widely criticized, but not a legal ground for abatement.
• "I filed everything as soon as I found out" — on its own, without explaining why you did not know earlier.
• Anything vague. "I was busy" and "I misunderstood the rules" without specifics get denied.

Two structural points that decide more cases than the narrative does:

Be specific with dates. A reasonable cause statement that says "I was unaware of the requirement until 2026" is weak. One that says "I formed the LLC on 4 March 2022 through [agent]; their service agreement, attached, covers registered agent and annual report only; I first learned of Form 5472 on 12 June 2026 from my bank's compliance email, attached; I faxed all delinquent years on 28 June 2026, receipt attached" is a chronology an appeals officer can act on.

File the missing returns first, or at the same time. An abatement request for a year that is still unfiled asks the IRS to forgive a failure that is still ongoing. Get the delinquent Form 5472 packages into Ogden, keep the timestamped fax receipts, and reference them by date in the letter.

What are the deadlines on a CP215 notice?

Read the notice itself — the response date is printed on it, and it governs. Two timing rules apply generally:

• Respond by the date on the notice. CP215 notices carry a short response window. Missing it does not permanently end your options, but it moves the matter toward collection.
• The 90-day clock. The Form 5472 instructions provide that if the failure continues for more than 90 days after IRS notification, an additional $25,000 penalty applies. The notice starts that clock. Filing the delinquent returns promptly is how you stop it.

If the response deadline is close and your package is not ready, a written request for additional time, sent before the deadline, is better than silence.

How do you respond to a Form 5472 penalty notice?

1. Read the notice and identify the tax year and the exact penalty code. Confirm the year matches a year you actually failed to file. Assessment errors happen — for instance, a penalty charged for a year in which the LLC did not yet exist, or for a year already filed by fax where you hold the receipt.
2. Pull your evidence. Fax confirmation receipts, formation documents, bank records showing when the LLC was funded, correspondence with any adviser or formation agent.
3. File every delinquent Form 5472 package still outstanding. Pro forma Form 1120 with "Foreign-owned U.S. DE" written across the top, Form 5472, and the Part V supporting statement — faxed to the Ogden PIN Unit at 855-887-7737, or mailed to Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.
4. Write the reasonable cause statement. Signed under penalties of perjury, addressed to the notice, with a dated chronology and attached documents. Reference the notice number and the LLC's EIN on every page.
5. Send it to the address on the notice — not to Ogden, not to a general IRS address. Use a method that gives you proof of delivery.
6. Keep everything and expect a wait. International penalty correspondence commonly takes six to twelve months for a substantive reply. Do not assume silence means acceptance.
7. If denied, you can appeal. The IRS Independent Office of Appeals reviews international penalty cases. At that stage, if the amounts justify it, engage a tax attorney or CPA who handles § 6038A matters.

What if you have several unfiled years?

Multiple unfiled years is the common case, and the arithmetic is unforgiving: five missed years is $125,000 of exposure. It is also the situation where getting the filings in fastest matters most, because the 90-day continuation penalty applies per year.

The practical sequence:

1. Identify every tax year the LLC existed and had a reportable transaction — including the year it was formed and funded.
2. Prepare a separate complete package for each year, on the form revision applicable to that year.
3. Fax them together with one cover letter and one reasonable cause statement covering the full period, and keep the transmission receipt.
4. Respond to any existing penalty notice separately, referencing that fax by date.

The one thing that never helps is waiting. Penalties accrue, the "voluntary before IRS contact" argument weakens the moment the IRS makes contact, and a longer gap makes the "I did not know" narrative harder to sustain.

Getting the delinquent filings done

Responding to a penalty notice has two halves. The abatement argument is yours — it depends on your facts, and if the amounts are large it deserves a tax attorney or CPA. The filings are mechanical, and that half is what we do.

Form5472 Prep prepares the complete package for each missing year — pro forma Form 1120, Form 5472, the Part V supporting statement, and a reasonable cause cover letter — has it reviewed by a qualified tax accountant, and faxes it to the IRS Ogden PIN Unit, returning the timestamped confirmation receipt you will cite in your response. Standard filings are $149 and ready in 5-7 business days; express is $199 in 3 business days; each additional past tax year is +$99.

We are not a CPA firm and we do not give tax advice. We prepare and submit the information returns accurately and fast, so the compliance half of your problem stops growing while you deal with the penalty half.

Start your filing here — about 15 minutes of your time, IRS fax delivery included.

Frequently asked questions

Can a $25,000 Form 5472 penalty be reduced or removed?

Yes, through reasonable cause abatement under IRC § 6038A(d)(3), or on appeal. Relief is not automatic and is not guaranteed. A written statement made under penalties of perjury, showing specific facts and dates and supported by documents, is materially more likely to succeed than a general explanation.

Does filing late with a reasonable cause letter prevent the penalty?

No. The IRS states that during processing of a delinquent international information return, penalties may be assessed without considering the attached reasonable cause statement. The statement preserves your argument for the correspondence stage that follows — it does not stop assessment.

Is the Form 5472 penalty per year or one flat amount?

Per form, per year. Three unfiled years means three separate $25,000 penalties. If a failure continues more than 90 days after IRS notification, the instructions provide for an additional $25,000 penalty for that year.

Do I owe the penalty if my LLC had no income?

Possibly, yes. Form 5472 reports transactions between the LLC and its foreign owner, not income. Funding the LLC's bank account is a reportable capital contribution. A dormant LLC with zero revenue can still be penalized for not filing.

What is IRS notice CP215?

CP215 is the "Notice of Civil Penalty Charge" the IRS commonly uses to assess penalties such as the Form 5472 penalty. It identifies the entity, the tax year, and the amount, and gives a date by which to respond.

Should I just pay the $25,000 penalty?

That is a decision for you and, at that amount, ideally a tax professional. Paying does not prevent you from later requesting a refund of the penalty on reasonable cause grounds, and it stops interest accruing. Ignoring the notice is the one option with no upside.

How long does the IRS take to respond to an abatement request?

Commonly six to twelve months for international penalty correspondence. Silence during that period is normal and should not be read as acceptance or denial. Keep proof of what you sent and when.
