Form 5472 Penalty Abatement: Reasonable Cause, the Abatement Letter, and Why First-Time Abate Does Not Apply

Published 2026-08-30 · Updated 2026-09-15 · Laramie Ledger Tax

TL;DR

First Time Abate does not apply to Form 5472 penalties. IRM 20.1.1.3.3.2.1 limits FTA to failure-to-file, failure-to-pay and failure-to-deposit penalties; IRC §6038A penalties are administered elsewhere. Reasonable cause is the only administrative route — and 26 CFR 1.6038A-4 requires the showing be made in a written statement under penalties of perjury. The “abatement letter” is that statement: your own facts, organised around the questions the IRS actually asks, filed after the late return. Whether relief is granted is the IRS’s decision.

How large is the penalty, and how fast does it grow?

$25,000 for each taxable year, per related party. 26 CFR 1.6038A-4 states that “a penalty of $25,000 shall be assessed for each taxable year” for failure to file Form 5472, failure to maintain records, or failure to comply with record-maintenance requirements.

The continuation mechanics are what turn a bad situation into a severe one:

  • The clock starts 90 days after the IRS mails notice of the failure.
  • After that, $25,000 per related party for each 30-day period the failure continues.
  • “Any uncompleted fraction of a 30-day period shall count as a 30-day period.”

That last clause means being one day into a new period costs the same as being thirty days into it. Two related parties and four continuation periods is $200,000 on top of the original assessment.

The practical consequence: if you are holding an IRS notice, the filing itself is urgent independently of the abatement argument. Filing stops the meter. Abatement addresses what has already accrued. See the full penalty mechanics.

Why First Time Abate does not help here

This is the most common and most expensive misconception about Form 5472 penalties.

First Time Abate is a narrow administrative waiver. IRM 20.1.1.3.3.2.1 lists exactly three penalty families:

  1. Failure to File under IRC 6651(a)(1), 6698(a)(1), or 6699(a)(1)
  2. Failure to Pay under IRC 6651(a)(2) and/or 6651(a)(3)
  3. Failure to Deposit under IRC 6656

Form 5472 penalties arise under IRC §6038A(d) and are administered under IRM 20.1.9 (international penalties), a separate part of the manual. They are not in the FTA list. Searching “first time penalty abatement Form 5472” leads to a door that does not open.

A clean three-year compliance history — the usual FTA qualifier — carries no automatic weight here. It is still worth stating in a reasonable cause request, because compliance history is one of the factors the IRS weighs under the ordinary business care standard. But it is evidence, not a waiver.

What “reasonable cause” actually requires

Ordinary business care and prudence. IRM 20.1.1.3.2 defines reasonable cause as relief that applies “when the taxpayer exercised ordinary business care and prudence in determining their tax obligations but was nevertheless unable to comply.” IRM 20.1.1.3.2.2 adds that a taxpayer establishes it “by providing facts and circumstances showing that they exercised ordinary business care and prudence (taking that degree of care that a reasonably prudent person would exercise), but nevertheless were unable to comply with the law.”

The IRS weighs four things:

FactorWhat it means in practice
Taxpayer’s ReasonDoes the stated cause actually explain the failure, and does it line up with the dates?
Compliance HistoryPrior filings, prior penalties, whether this is a pattern (the IRS looks back at least three years)
Length of TimeHow long between the cause ending and compliance beginning
Circumstances Beyond ControlWhether the event was genuinely outside the taxpayer’s control, and whether it could have been anticipated

The regulation adds specifics for §6038A that the general IRM does not:

  • “Isolated computational or transcriptional errors generally are not inconsistent with reasonable cause.” A clerical slip does not defeat the claim.
  • Reliance on professional advice can support reasonable cause, but the reliance must have been reasonable under all the circumstances.
  • Not knowing you were foreign-owned can matter: the regulation contemplates a taxpayer who “does not know or has no reason to” suspect the ownership that triggers the requirement.

The procedural requirement most requests get wrong

26 CFR 1.6038A-4 does not just ask for an explanation. It requires:

“an affirmative showing of all the facts alleged as reasonable cause” in “a written statement containing a declaration that it is made under penalties of perjury.”

Two obligations sit inside that sentence.

“All the facts.” A partial narrative is not an affirmative showing. Dates, who knew what and when, what the taxpayer did once they learned, and why the delay ran as long as it did all belong in the statement.

“Under penalties of perjury.” The declaration is not boilerplate. It converts the narrative into a sworn statement, and it is the reason a reasonable cause request should never contain a fact the taxpayer cannot support. IRM 20.1.9 repeats the point for international penalties: requests for abatement due to reasonable cause “should contain a declaration that it is made under the penalties of perjury.” In our experience reviewing these, an omitted perjury declaration is one of the quiet reasons a well-argued request goes nowhere.

How to structure the abatement letter

There is no IRS form for a Form 5472 reasonable cause request. The “letter” is the written statement the regulation describes, and its structure should follow the questions the IRS says it asks. IRM 20.1.1.3.2 lists them:

  1. “What happened and when did it happen?”
  2. During the period of noncompliance, “what facts and circumstances prevented the taxpayer from filing” or otherwise complying?
  3. “How did the facts and circumstances result in the taxpayer not complying?”
  4. “How did the taxpayer handle the remainder of their affairs during this time?”
  5. “Once the facts and circumstances changed, what attempt did the taxpayer make to comply?”

A statement that answers those five, in that order, with dates, is doing what the reviewer needs. An outline that works:

SectionWhat goes in it
HeadingReporting corporation’s name and EIN, tax year(s), “Form 5472 / IRC §6038A(d) penalty”, the CP215 notice number and date if one was received
RequestOne sentence: the taxpayer requests abatement of the §6038A(d) penalty for reasonable cause under 26 CFR 1.6038A-4(b)
1. BackgroundWhen the LLC was formed, who owns it, where the owner lives, what the LLC did in the year, what the reportable transactions were (often only capital contributions or owner-paid expenses)
2. What happened and whenThe specific facts, in date order: who was engaged, what they were told, what advice was given, when the owner first learned of the Form 5472 requirement and how
3. Why those facts prevented filingThe link between the facts and the miss — reliance on a professional who was given the full facts, an event outside the owner’s control, an ownership fact the owner had no reason to suspect. Not “I did not know” on its own
4. How other affairs were handledThe state annual report was filed, the bank account was maintained, the EIN was obtained, other returns were on time — the picture of a prudent operator
5. What was done once the facts changedThe date the late Form 5472 and pro forma 1120 were filed (before or promptly after the notice), and how the process was fixed for future years
Small corporation provisionIf gross receipts are $20,000,000 or less: state it, cite 26 CFR 1.6038A-4(b)(2)(ii), and show the limited U.S. presence and the prompt compliance
Compliance historyPrior years filed, no prior penalties — as evidence, not as an FTA claim
Declaration”Under penalties of perjury, I declare that I have examined this statement, including any accompanying documents, and to the best of my knowledge and belief it is true, correct, and complete.” Signed and dated by an authorised person for the reporting corporation, with title
AttachmentsEngagement letters, e-mails with advisers, formation documents, bank records that fix the dates, proof the late return was filed

Three cautions that matter more than the outline.

The facts must be the owner’s own. A professional U.S. tax preparer can organise a statement, cite the regulation and check that every question is answered. What no preparer can do is supply the facts. The declaration under penalties of perjury is signed by the taxpayer, about the taxpayer’s own history; a statement built from a template’s “typical” story, or from facts the owner cannot document, is worse than a short honest one. We do not invent facts, and a request that needs invented facts should not be sent.

Short and specific beats long and general. Two pages with six dates and three attachments will be read. Eight pages of adjectives will not.

Keep the IRS’s decision where it belongs. The statement makes the showing; the IRS decides whether it meets the standard. Nothing in the process is a guarantee, and anyone who promises abatement for a fee has not read the regulation.

Where it goes: if the late return is filed before any notice, the statement is submitted with the return. If a CP215 has already been issued, it is sent in response to the notice, to the address the notice gives, quoting the notice number, tax year and EIN. Keep proof of mailing either way.

The small corporation rule almost nobody cites

26 CFR 1.6038A-4 contains a provision written for exactly the profile of a foreign-owned single-member LLC. The District Director shall apply the reasonable cause exception liberally for a small corporation that meets the stated criteria — including gross receipts of $20,000,000 or less, limited US presence, and prompt compliance once the IRS requests it.

Nearly every foreign-owned LLC filing a dormant or near-dormant Form 5472 sits far inside that threshold. If the request does not raise this provision by name, it is leaving the most favourable standard in the regulation on the table.

Note the third condition: prompt compliance upon request. It rewards taxpayers who file immediately on receiving the notice and penalises those who wait. This is another reason the filing and the abatement request are separate decisions with separate urgency.

What reasonable cause is NOT

Being clear about the boundaries makes a stronger request than overreaching.

  • Not ignorance of the requirement alone. “I did not know Form 5472 existed” is not, by itself, ordinary business care. It becomes relevant only when combined with facts showing why a prudent person in the same position would also not have known.
  • Not “my formation agent never told me.” Reliance on a non-adviser is weak. Reliance on a tax professional who was engaged, given the facts, and gave incorrect advice is a different and much stronger argument.
  • Not “the LLC had no income.” The filing obligation is triggered by reportable transactions, not profit. A zero-income year is why the return was required, not an excuse for missing it. See why a zero-income LLC still files.
  • Not First Time Abate. See above.
  • Not a payment plan. Abatement removes the penalty; an instalment agreement only spreads it.

A separate line of defence: supervisory approval

IRC §6751(b) requires that the initial determination of certain penalty assessments be personally approved in writing by the immediate supervisor of the person making it. Where the penalty was assessed systemically, whether that approval exists — and whether it was timely — is a distinct procedural question from reasonable cause.

This is a technical argument, it does not apply to every assessment, and it belongs with a practitioner rather than in a self-prepared letter. It is worth knowing it exists, because it survives even where the reasonable cause narrative is weak.

The CP215 notice, and what to do when it arrives

The notice for a Form 5472 penalty is usually a CP215, Notice of Penalty Charge. IRM 20.1.9 identifies it as the notice generated for IRC 6038A penalties assessed on a business account. The IRS’s own description is short: “We sent you this notice because we charged you a civil penalty,” and it “explains your due date, amount due, and payment options.” It also tells you to contact the IRS if you disagree — the reasonable cause statement is how you do that. (You may also see notices about a proposed penalty or a request for the missing return before a CP215; the response is the same: file, then make the showing. How to read an IRS notice to a foreign-owned LLC covers the other letters.)

Working order matters more than speed:

  1. Read the notice for the tax year and the amount. Confirm which year and which related party the penalty attaches to.
  2. File the delinquent Form 5472 with a pro forma Form 1120 immediately — this stops the continuation penalty and satisfies the “prompt compliance” condition in the small corporation rule.
  3. Note the 90-day mark from the notice date. That is when continuation penalties begin.
  4. Assemble the facts before drafting. Formation date, when the reportable transaction occurred, who advised you, what you were told, when you learned of the obligation, what you did next.
  5. Draft the reasonable cause statement covering all the facts in the structure above, cite the small corporation provision if gross receipts are $20M or less, and include the declaration under penalties of perjury.
  6. Keep the evidence. Engagement letters, emails with advisers, bank records establishing dates. An affirmative showing is only as good as what supports it.
  7. Diarise the response deadline on the notice. Missing it forfeits options that are not easily recovered.

Next Steps

A Form 5472 penalty notice has two clocks running at once — the continuation clock at 90 days, and the response deadline printed on the notice. The filing that stops the first is mechanical and should not wait on the abatement analysis. If you are holding a CP215 and are not sure which year it attaches to or whether the small corporation provision applies to your facts, that assessment is a short, fixed-scope review.

Frequently Asked Questions

Does first-time penalty abatement apply to Form 5472?
No. IRM 20.1.1.3.3.2.1 limits First Time Abate to failure-to-file, failure-to-pay and failure-to-deposit penalties under IRC 6651, 6698, 6699 and 6656. The Form 5472 penalty arises under IRC 6038A and is administered under IRM 20.1.9 (international penalties); it is not on the FTA list. Reasonable cause is the only administrative route.
How much is the Form 5472 civil penalty?
$25,000 for each taxable year, per related party, under 26 CFR 1.6038A-4. If the failure continues more than 90 days after the IRS mails notice, an additional $25,000 applies for each 30-day period, and any fraction of a 30-day period counts as a full one.
What is the standard for reasonable cause on a Form 5472 penalty?
Ordinary business care and prudence. The taxpayer must make an affirmative showing of all facts alleged as reasonable cause in a written statement containing a declaration that it is made under penalties of perjury (26 CFR 1.6038A-4(b)).
What should a Form 5472 penalty abatement letter contain?
The facts the IRS asks about in IRM 20.1.1.3.2: what happened and when, how those facts prevented filing, how you handled your other affairs in the period, and what you did to comply once the facts changed. Plus the tax year, EIN, notice number, the small-corporation provision if gross receipts are $20 million or less, and the declaration under penalties of perjury. The facts must be your own.
Is there special relief for small companies?
Yes. 26 CFR 1.6038A-4(b)(2)(ii) directs that the reasonable cause exception be applied liberally for a small corporation with gross receipts of $20,000,000 or less, limited U.S. presence, and prompt compliance once the IRS requests it.
What is a CP215 notice?
CP215, Notice of Penalty Charge, is the IRS notice for a civil penalty assessed on a business account — the notice used for IRC 6038A penalties per IRM 20.1.9. It states the tax year, the amount, the due date and payment options, and tells you to contact the IRS if you disagree. That contact is the reasonable cause request.
Does filing the late Form 5472 stop the penalty from growing?
Filing stops the continuation penalty, which accrues per 30-day period after the 90-day mark. Filing does not by itself remove the initial $25,000 — that requires a reasonable cause showing, and the IRS decides whether to grant it.
Can I get a Form 5472 penalty abated over the phone, and does a clean history help?
Not by phone — the regulation requires a written statement under penalties of perjury. A clean filing history helps as evidence under the ordinary business care standard, but it is not an automatic waiver the way First Time Abate is for other penalties.
