Form 5472 Penalty Abatement Letter: How to Write the Reasonable Cause Statement (with Template)

A $25,000 Form 5472 penalty is not final. The regulation behind it, Treas. Reg. §1.6038A-4(b), lets the IRS remove it when the LLC "acted in good faith and there is reasonable cause", and it tells the IRS to apply that exception "liberally" to small companies that did not know the rule. The letter you send is how you prove it.

This guide covers what that letter must contain, how to make it convincing, and where to send it. It ends with a template you can adapt. Unless another source is named, the rules come from Treas. Reg. §1.6038A-4(b) and the IRS manual's section on this penalty, IRM 20.1.9.5.

In short:

• The regulation 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". A short, unsigned or generic letter does not meet that standard.
• For a "small corporation" (gross receipts of $20,000,000 or less), the IRS "shall apply the reasonable cause exception liberally" if it had no knowledge of the rule, has limited presence in and contact with the United States, and promptly and fully complies with IRS requests. Build your letter around those three points.
• File every missing year first. The manual recommends that reasonable cause "not be considered for any year until all delinquent returns have been filed".
• Reasonable cause stops 90 days after the IRS notice at the latest, so it cannot remove the continuation penalty. Never let a notice sit.
• If you were penalized automatically on a late pro forma Form 1120, the earliest year may also qualify for First Time Abate (FTA).
• If the IRS refuses, its letter tells you how to appeal. For penalty appeals the IRS generally gives 30 days.

When you need the letter

There are two moments, and the letter is almost the same in both.

1. When you file late, before the IRS writes to you. Attach the statement to each late Form 5472 and pro forma Form 1120. The IRS warns that this does not guarantee anything: "During the processing of the delinquent information return, penalties may be assessed without considering the attached reasonable cause statement. It may be necessary for taxpayers to respond to specific correspondence from the IRS and submit or resubmit reasonable cause information" (delinquent international information return procedures). The IRS manual confirms that the penalty "may be systemically asserted" when a late Form 5472 arrives attached to a late Form 1120.
2. After you receive a penalty notice. Once the penalty is assessed, the IRS manual says a CP215, Notice of Penalty Charge, is sent. You then send the statement again, in response to that notice. This is the request that gets reviewed.

Filing first and attaching the statement still matters. It shows good faith from day one, and the statement is ready when the notice arrives.

What the IRS must see: the legal standard for Form 5472

The Form 5472 penalty has its own reasonable cause rule, written for section 6038A. It is more favorable to foreign owners than the general rules many templates are based on.

1. Good faith and reasonable cause, shown in writing. Section 1.6038A-4(b)(1) excuses a failure "if an affirmative showing is made that the taxpayer acted in good faith and there is reasonable cause". Paragraph (b)(2)(i) adds that the reporting corporation "must make an affirmative showing of all the facts alleged as reasonable cause for the failure in a written statement containing a declaration that it is made under penalties of perjury".

2. The small corporation rule. Paragraph (b)(2)(ii) is the most useful sentence for a founder abroad:

"The District Director shall apply the reasonable cause exception liberally in the case of a small corporation that had no knowledge of the requirements imposed by section 6038A; has limited presence in and contact with the United States; and promptly and fully complies with all requests by the District Director to file Form 5472, and to furnish books, records, or other materials relevant to the reportable transaction. A small corporation is a corporation whose gross receipts for a taxable year are $20,000,000 or less."

Three conditions, and your letter should prove each one:

3. Facts and circumstances. Paragraph (b)(2)(iii) says the decision "is made on a case-by-case basis, taking into account all pertinent facts and circumstances", and that reasonable cause can include "an honest misunderstanding of fact or law that is reasonable in light of the experience and knowledge of the taxpayer".

Why not to copy a generic template. The IRS's general penalty relief page says that, for failure-to-file and failure-to-pay penalties, "lack of knowledge" generally does not qualify. The Form 5472 regulation is different: lack of knowledge is one of the three conditions it names for small corporations. A letter that cites only the general rules, or argues "illness" or "disaster" when that is not your story, misses the rule that actually helps you.

The IRS manual's general chapter also helps. On ignorance of the law, IRM 20.1.1.3.2.2.6 says reasonable cause may exist if "the taxpayer was unaware of a requirement and could not reasonably be expected to know of the requirement", taking into account factors such as "the taxpayer's education", whether the taxpayer "has previously been subject to the tax", and "the level of complexity of a tax or compliance issue" (IRM 20.1.1).

Before you write: three things to check

1. Every missing year is filed. Under IRM 20.1.9.5.5, "it is recommended that reasonable cause not be considered for any year until all delinquent returns have been filed". File them all first; our catch-up guide shows how.
2. The 90-day clock. The manual is direct: "the latest date reasonable cause can exist is 90 days from the date of notification of the failure by the Service. … As such, there is no reasonable cause exception for this penalty", meaning the continuation penalty of $25,000 per 30-day period. If you have a notice, file the missing returns within 90 days of it.
3. Your story holds up. The regulation asks for "all the facts", and a false statement under penalties of perjury is far worse than the penalty. Write only what you can support with documents.

What a strong statement contains

Five parts, in this order.

1. Identification. The LLC's name and EIN, each tax year concerned, the penalty amount, the notice number and date if you have one, and the section involved: "section 6038A(d)".
2. The request. One sentence that asks for abatement of the penalty for each year "under Treas. Reg. §1.6038A-4(b)", and, if it applies, under First Time Abate (see below).
3. The facts, in date order. When and why the LLC was formed, who handled the formation, what you knew, how you learned about Form 5472, and exactly when you filed each return. The IRS manual's own questions are a good outline: "What happened and when did it happen? … Once the facts and circumstances changed, what attempt did the taxpayer make to comply?"
4. The legal argument. One paragraph per small-corporation condition, each with its evidence.
5. The declaration and signature. The penalties of perjury declaration, then the signature of the LLC's owner with your title (for example "Sole member"). On Form 843, the IRS requires that a corporation's officer sign "and the officer's title must be included".

Evidence to attach (copies, never originals):

• the formation documents and the formation provider's invoice or welcome email, showing what was and was not included;
• proof of where you live (for example a residence certificate or a tax return from your country);
• the LLC's bank statements, showing few or no US transactions;
• proof of the date you filed each late return (fax transmission report or tracking);
• the IRS notice, if any.

What weakens the letter

• Blaming your formation provider or accountant. The regulation says reliance on professional advice "does not necessarily demonstrate reasonable cause", unless "under all the circumstances, the reliance was reasonable". If someone advised you, explain what they knew and what they told you, and attach it.
• "I forgot." The IRS manual: forgetfulness "generally … does not provide a basis for reasonable cause", and filing responsibility "cannot be delegated".
• Vague wording. "Due to circumstances beyond our control" without dates or facts is what the regulation calls the opposite of an affirmative showing.
• Facts that contradict your filings. If your Form 5472 shows $40,000 of contributions and a US warehouse, "limited presence" needs explaining, not asserting.
• Waiting. Once the facts that explained the delay are gone, the manual says reasonable cause "does not exist if … the taxpayer fails to comply with the tax obligation within a reasonable period of time".

First Time Abate: an extra route for one year

First Time Abate (FTA) normally does not apply to Form 5472: the manual says FTA does not apply to "event-based filing requirements such as with Form 5472". It does make one exception, in IRM 20.1.9.5.5(3).

When the penalty is assessed automatically because Form 5472 was attached to a late Form 1120, it may be removed under FTA if the late Form 1120 itself qualified for FTA, or "would have been eligible for FTA abatement but a failure to file penalty wasn't assessed because there was $0 tax due". A pro forma Form 1120 shows $0 tax, so this can apply. Two more conditions:

• "The taxpayer had no similar penalties (PRNs 625 or 711) in the three prior periods";
• "The related Form 1120 return was not filed late in the three prior periods".

In practice, this means FTA can only help for the earliest missing year: every later year fails the second test. Ask for FTA on that year and rely on reasonable cause for the others. The manual adds that if FTA does not apply, "penalty relief is still available when reasonable cause can be demonstrated".

For 2025 and later years, the IRS is replacing FTA with an automatic relief called AEP (IRS administrative relief page). How the manual's Form 5472 exception applies to those years has not been published, so ask for both FTA and reasonable cause.

Where and how to send it

Form 843 (Claim for Refund and Request for Abatement) is the IRS form for this request. At the top, check "Abatement or refund of a penalty or addition to tax due to reasonable cause or other reason allowed under the law"; on line 6 write "6038A"; check box 7c; and on line 8 write "See attached reasonable cause statement". Use one Form 843 per tax year. Our catch-up guide shows a completed Form 843.

By phone. The IRS says it "may reduce or remove some penalties over the phone" using the number on your notice. For a $25,000 penalty, we recommend the written request with the full statement: it creates a record. If you call, note the date and the name or ID of the person you spoke to.

Interest. Interest runs on an unpaid penalty after the notice's due date. If the penalty is removed, the IRS says it will "automatically reduce or remove the related interest".

Keep proof of everything: fax transmission reports, tracking numbers, and a full copy of what you sent.

Adapt every bracket to your facts and delete what does not apply. Do not keep a sentence you cannot support.

REASONABLE CAUSE STATEMENT
Request for abatement of penalties under section 6038A(d)

[Date]

Internal Revenue Service
[Return address shown on the notice, or: Attn: PIN Unit, M/S 6112, 1973 Rulon White Blvd, Ogden, UT 84201]

Taxpayer: [LLC legal name], a foreign-owned U.S. disregarded entity
EIN: [XX-XXXXXXX]
Tax year(s): [2023, 2024]
Penalty: [$25,000 for each year], section 6038A(d) [Notice CP215 dated [date], if any]

Request. [LLC name] requests abatement of the penalties listed above under Treas. Reg. §1.6038A-4(b), because its failure to file Form 5472 on time was due to reasonable cause and not to a lack of good faith. [For the earliest year: For tax year [year], [LLC name] also requests First Time Abate under IRM 20.1.9.5.5(3).]

Facts.

1. I am a [citizen and resident of France], and I have lived and worked in [country] throughout the years concerned. I have never lived in the United States.
2. On [date], I formed [LLC name] in [state] through [formation provider], to [invoice clients / sell software] from [country]. The formation package included the Articles of Organization, an EIN and a registered agent. It did not include, or mention, any federal filing obligation. [Attachment 1]
3. The LLC has no office, employees, inventory or agent in the United States other than its registered agent. Its only US contacts are the registered agent, its bank account at [bank] and [payment processor]. [Attachment 2]
4. [If true: The LLC had no income effectively connected with a US trade or business and owed no US income tax.] Its reportable transactions were [capital contributions of $X and distributions of $Y] between the LLC and me.
5. I first learned of the Form 5472 requirement on [date], when [describe: an accountant in my country / my bank / a client] told me about it. [Attachment 3]
6. Within [number] days, on [date], I filed Form 5472 and the pro forma Form 1120 for every year concerned, by fax to 855-887-7737. [Attachment 4: transmission reports]

Reasonable cause. Treas. Reg. §1.6038A-4(b)(2)(ii) provides that the reasonable cause exception shall be applied liberally to a small corporation that had no knowledge of the requirements of section 6038A, has limited presence in and contact with the United States, and promptly and fully complies with IRS requests.

• Small corporation: the LLC's gross receipts were [$X] in [year] and [$Y] in [year], well under $20,000,000.
• No knowledge: as a non-US resident [with no US tax background], I had no knowledge of section 6038A or of the filing obligation of a foreign-owned disregarded entity, which applies even when no US tax is due. Nothing in the formation documents mentioned it (paragraphs 2 and 5).
• Limited presence in and contact with the United States: see paragraph 3.
• Prompt and full compliance: I filed every missing return within [number] days of learning of the requirement (paragraph 6), and I will answer any further IRS request promptly.

I acted in good faith throughout. As soon as I learned of the requirement, I corrected the failure for every year[, and the LLC has filed on time since].

Declaration. Under penalties of perjury, I declare that I have examined this statement, including the accompanying attachments, and, to the best of my knowledge and belief, the facts presented are true, correct, and complete.

[Signature]
[Full name], Sole member, [LLC name]

Attachments: [list]

If the IRS says no

• Read the refusal letter. It tells you whether you can appeal and by when. On its penalty appeal page, the IRS says you "generally have 30 days from the date of the rejection letter" to request an appeal, and points to Publication 4576, Orientation to the Penalty Appeals Process.
• Appeal with more facts, not the same letter. Appeals is an independent office: add the evidence and the dates that were missing.
• Ask for help if you are stuck. The Taxpayer Advocate Service is an independent organization within the IRS that helps taxpayers who cannot resolve a problem through normal channels.

Our Penalty & Notice Resolution bundle prepares the full request for you: the late returns if any remain, the statement and evidence file, Form 843, and the reply to the notice. We prepare it for you to sign; we do not represent clients before the IRS.

Frequently asked questions

Is there an official IRS form for the reasonable cause statement?

No. The regulation only requires "a written statement containing a declaration that it is made under penalties of perjury" that makes "an affirmative showing of all the facts". You write it yourself and attach it to the late return or to Form 843.

Who signs the letter for a single-member LLC?

You, as the owner, with your title, for example "Sole member". The statement is made for the LLC, which the IRS treats as the reporting corporation, and the Form 843 instructions require a corporation's signer to include their title.

Does not knowing about Form 5472 really count as reasonable cause?

For this penalty, it can. The general IRS rules say lack of knowledge usually does not qualify, but the Form 5472 regulation tells the IRS to apply reasonable cause "liberally" to a small corporation that "had no knowledge of the requirements imposed by section 6038A", as long as it also has limited US presence and complies promptly once it knows. Lack of knowledge alone, without the other two, is weaker.

Can reasonable cause remove the extra $25,000 per month after a notice?

No, not for the time after the 90 days. Under the regulation and IRM 20.1.9.5.5, reasonable cause can last no later than 90 days after the IRS notice, so "there is no reasonable cause exception" for the continuation penalty. That is why the missing returns must be filed within 90 days of any notice.

How long does the IRS take to answer?

The IRS does not publish a set time for these requests. Keep proof of your filing, and if you get a reply that you disagree with, check the deadline in the letter right away.

Should I pay the penalty while I wait?

That is your choice. Interest accrues on an unpaid penalty after the due date on the notice, and the IRS removes the related interest if it removes the penalty. Form 843 is used both to request an abatement and to claim a refund, so paying does not prevent you from asking for the penalty back.
