Form 5472 penalty abatement letter — reasonable cause statement template for foreign-owned LLC owners

The short answer

This page gives you the letter itself— a complete, copyable reasonable-cause request for a $25,000 Form 5472 penalty, plus three filled-in versions for the situations foreign founders actually face. There is no official IRS form for this request: you write, sign, and send it yourself. It must accompany the delinquent Form 5472, not replace it.

Before you use this

This is a template you complete and sign yourself

form5472.tax prepares and files Form 5472 and the pro forma Form 1120 for a flat $299, and can include a reasonable-cause statement with a delinquent filing. We do not represent clients before the IRS.

What this page is
An educational template. You supply the facts, you sign it, you send it.
What we do not do
Draft, sign, submit, or argue an abatement request on your behalf. That is representation, and it requires a licensed CPA, enrolled agent, or tax attorney.
Relief is discretionary
The IRS decides. No letter, however well written, guarantees abatement.
If the amount is large
Or if you have multiple years, an open examination, or a denial to appeal — engage a credentialed representative rather than writing this alone.

The full Form 5472 penalty abatement letter template

Copy the letter below and replace every bracketed field. It is structured the way the IRS reads a reasonable-cause request: what happened, why it was reasonable, what you did about it, your compliance history, and the request itself — ending with the penalties-of-perjury declaration that a request needs to be considered.

There is no IRS form for this. A reasonable-cause request for a section 6038A penalty is a letter you write. That freedom is why so many requests fail: without a structure, people write a paragraph of apology with no dates, no documents, and no statement of what they did to fix it — and the IRS has nothing to weigh.

The five numbered sections below are not decoration. They map to what the IRS is actually assessing: whether you exercised ordinary business care and prudence, and whether the failure was corrected promptly once discovered.

RE:  Request for penalty abatement — reasonable cause
     Taxpayer:            [LLC legal name]
     EIN:                 [XX-XXXXXXX]
     Form:                Form 5472 (with pro forma Form 1120)
     Tax year(s):         [YYYY]
     Notice number:       [CP215 / CP162 / other, if you received one]
     Notice date:         [Date on the notice, if any]

To Whom It May Concern:

I am the sole member of [LLC legal name], a [State] limited liability company,
and I am writing to request abatement of the penalty assessed under Internal
Revenue Code section 6038A(d) for the [YYYY] tax year, on the grounds of
reasonable cause.

1. WHAT HAPPENED

[State the facts in plain, chronological order. When the LLC was formed, what it
did, when you first learned Form 5472 applied to you, and how you learned it.
Give dates. Do not argue and do not editorialise — the facts do the work.]

2. WHY THIS CONSTITUTES REASONABLE CAUSE

I exercised ordinary business care and prudence, but was nevertheless unable to
file on time because [state the single clearest reason]. [Explain in two or
three sentences why a reasonable person in your position would have acted the
same way. Tie it to the specific facts in section 1, not to general hardship.]

3. WHAT I DID WHEN I DISCOVERED THE FAILURE

Upon learning of the requirement on [date], I acted immediately to correct it.
The delinquent Form 5472 for [YYYY], together with the required pro forma
Form 1120, [was filed on / is enclosed with] this letter. [Describe any other
corrective steps: engaging a preparer, filing other outstanding years, setting
up a compliance calendar.]

4. MY COMPLIANCE HISTORY

[State it plainly. Either: this is my first failure of any kind and the entity
has no other delinquent filings or unpaid balances. Or: describe the history
accurately. Do not overstate it — the IRS can see your account.]

5. REQUEST

I respectfully request that the penalty assessed under section 6038A(d) for the
[YYYY] tax year be abated in full on the basis of reasonable cause. The failure
was not willful, was not the result of neglect, and was corrected as soon as I
became aware of it.

Enclosed:
  - Form 5472 for [YYYY] with pro forma Form 1120
  - [Copy of the IRS notice, if you received one]
  - [Supporting documents: correspondence, invoices, engagement letters,
     medical records, or anything else that evidences the facts above]

I declare, under penalties of perjury, that the facts stated in this letter are
true, correct, and complete to the best of my knowledge and belief.

Sincerely,

Replace every bracketed field. Delete any bracketed instruction text before sending — the letter should contain your facts, not the prompts.

Keep it to one or two pages. A reasonable-cause request is not improved by length; it is improved by dates, documents, and a single clear reason.

Three filled-in examples the IRS sees most often

Section 2 is where the request is won or lost. Below are three versions of it — the new founder who did not know, the founder who relied on a formation service that never filed, and the non-resident with no US tax background. Use the one that matches your facts, and use only one.

Each of these replaces section 2 of the template. Everything else in the letter stays as written. Resist the temptation to combine them: a request built on one well-evidenced reason is far stronger than one that offers three, because offering three signals that none of them is sufficient alone.

Example 1 — first-time founder who did not know the requirement existed

The most common situation by far. On its own, not knowing the law is generally notreasonable cause — so this version does not rest on ignorance. It rests on the surrounding facts: no US filing history, nothing in the formation or EIN paperwork that flagged the obligation, and immediate correction on discovery.

Example 1 — new founder, no prior US filing history
2. WHY THIS CONSTITUTES REASONABLE CAUSE

I formed [LLC legal name] on [date] as a first-time business owner living
outside the United States. I had never held a US company, had no US tax filing
history, and no US income. I understood — incorrectly, but in good faith — that
a company with no revenue and no US-source income had nothing to file, and that
any obligation would arise only once the business began earning.

No one advised me otherwise. The formation service I used did not mention
Form 5472, the state filing confirmation did not reference any federal
information return, and the EIN confirmation letter (CP 575) I received on
[date] listed no Form 5472 filing requirement.

I learned of the requirement on [date], when [describe: an accountant mentioned
it / I received notice CP215 / I read about it while preparing for year two].
I filed the delinquent return [immediately / within X days] of learning of it.

Example 2 — relied on a formation service that never filed it

The strongest of the three when it is true, because reliance on an engaged provider is squarely within ordinary business care and prudence. It depends entirely on evidence: what you paid for, what was advertised, and the absence of any communication from the provider about Form 5472. Attach the engagement page and the receipt.

Example 2 — formation service engaged for compliance did not file
2. WHY THIS CONSTITUTES REASONABLE CAUSE

I engaged [formation service name] on [date] and paid $[amount] for a package
advertised as covering my company's ongoing US compliance. Their materials
described the service as handling my annual filing obligations, and I relied on
that representation. Copies of the engagement page and my payment receipt are
enclosed.

I reasonably believed my Form 5472 obligation was being handled. I received no
communication from [formation service name] indicating that Form 5472 was
outside the scope of what I had purchased, no request for the transaction
information the form requires, and no draft return to review or sign for the
[YYYY] tax year.

Reliance on a service provider engaged for exactly this purpose is ordinary
business care and prudence. I discovered the failure on [date], when [describe],
and immediately [engaged a specialist preparer / filed the delinquent return].

Example 3 — non-resident with no US tax background

This version leans on the genuine narrowness of the rule. A foreign-owned single-member LLC being treated as a corporation solely for section 6038A reporting is a 2017 provision (T.D. 9796) that a non-resident will not meet through ordinary diligence, and saying so accurately is legitimate.

Example 3 — no US filing history, different home-country treatment
2. WHY THIS CONSTITUTES REASONABLE CAUSE

I am a resident and citizen of [country] and have never lived, worked, or filed
a tax return in the United States. My only connection to the US tax system is
[LLC legal name], which I formed on [date] to [purpose].

In [country], a company with no income and no distributions files [describe the
equivalent local treatment briefly — e.g. a nil return, or nothing at all]. I
applied that understanding to my US company in good faith. The specific rule
that a foreign-owned single-member LLC is treated as a corporation solely for
section 6038A reporting — and must therefore file Form 5472 with a pro forma
Form 1120 even with zero income — is a narrow provision that took effect for tax
years beginning on or after January 1, 2017 (T.D. 9796), and it is not one a
non-resident encounters through ordinary diligence.

On learning of it on [date] I acted at once: [describe the corrective steps].

If your circumstances involve serious illness, bereavement, or a natural disaster, state those facts plainly in section 2 with dates and documentation. Those are recognised reasonable-cause grounds and do not need the supporting scaffolding the three versions above require.

How to complete the letter, step by step

Gather your dates, file the delinquent return, write the chronology, state one clear cause, show what you did on discovering the failure, attach the evidence, sign under penalties of perjury, and send it to the address on your notice — or to the Ogden PIN Unit if you have not received one.

Completing a Form 5472 reasonable-cause letter
StepWhat to doWhy it matters
1. Gather the facts and datesWrite down when the LLC was formed, when it was funded, when you first learned Form 5472 applied, and how you learned it.Every claim in the letter needs a date behind it.
2. Prepare and file the delinquent returnComplete Form 5472 with a pro forma Form 1120 for each unfiled year.The letter accompanies a filing; it does not replace one.
3. Write section 1 as plain chronologyState what happened in order, without argument.Facts persuade; adjectives do not.
4. State one clear reasonable causePick the single strongest reason and develop it.Several weak reasons read as excuses and weaken each other.
5. Show immediate corrective actionGive the date you discovered the failure and what you did next.Prompt correction is among the strongest facts available to you.
6. Attach the evidenceEnclose the return, the notice if you received one, and any correspondence, receipts, or engagement letters that evidence the facts you stated.
7. Sign under penalties of perjuryInclude the perjury declaration and sign it by hand.An unsigned request can be set aside without consideration.
8. Send it to the right addressUse the address on the notice if you have one.Otherwise send it with the return to the Ogden PIN Unit. Keep dated proof of mailing.

The single most consequential step is the second one. A request for relief on a return that is still unfiled is very unlikely to succeed, because the continuation penalty is still running while the IRS considers it. File first, then ask.

What to attach to the letter

The delinquent Form 5472 and pro forma 1120, the IRS notice if you received one, and documents that evidence the specific facts you stated — engagement pages, payment receipts, correspondence, medical or travel records. An assertion with a document behind it carries weight; the same assertion alone usually does not.

Reasonable cause is a facts-and-circumstances determination. That phrase means exactly what it says: the IRS is weighing your particular facts, and it can only weigh what you put in front of it.

Redact nothing that matters and attach copies, never originals. If a document is not in English, include a translation.

Where to send the letter

If you received a notice, use the address printed on it — that routes the letter to the unit holding your case. If you are filing voluntarily with no notice, attach the statement to the Form 5472 package and send it to the Ogden PIN Unit, or fax it to 855-887-7737.

Address routing matters more here than people expect. A reasonable-cause letter sent to a general address while your case sits with a specific unit can simply not reach the person deciding it.

The mechanics of both routes — envelope addressing, cover sheets, and confirming receipt — are on the fax and mailing guide.

What weakens a reasonable-cause request

Stacking several weak reasons instead of one strong one, writing without dates, asserting facts with no documents, asking for relief while the return is still unfiled, blaming the IRS, and leaving out the penalties-of-perjury declaration. Each is avoidable.

Common failures in a Form 5472 abatement request
MistakeWhy it hurtsDo this instead
Several reasons at onceOffering three signals that none is sufficient alonePick the strongest and develop it properly
No datesThe IRS cannot assess promptness without a timelineDate every event, especially discovery and correction
Assertions with no documentsFacts-and-circumstances means documents, not adjectivesAttach the engagement page, receipt, or record
Asking before filingThe continuation penalty is still accruing while they read itFile the delinquent return with or before the letter
Blaming the IRS or the ruleReads as argument, not reasonable causeState facts neutrally; let them carry the point
Emotional appeal without factsHardship alone is not the statutory testTie every hardship to a date and a document
No perjury declaration or signatureAn unsigned request can be set aside unreadInclude the declaration and sign by hand

One more, less obvious: do not claim a clean compliance history you do not have. The IRS can see your account, and an overstatement in section 4 undermines the credibility of sections 1 through 3.

What happens after you send it

Expect six to twelve months, sometimes longer for international filers. If relief is granted the penalty is removed or refunded. If it is denied, you may ask the IRS Independent Office of Appeals to review it within the deadline on the denial letter — an appeal should be handled by a licensed representative.

Silence during that window is normal and is not a signal either way. Keep your dated proof of mailing; it is the only evidence that the request was made on the date you say it was.

If you have unfiled years beyond the one you are asking about, deal with them too. Each unfiled Form 5472 is a separate $25,000 penalty with no cap and no statute of limitations, and a request for relief on one year sits awkwardly beside three others still outstanding. The catch-up filing guide covers clearing several years at once, and the penalty calculator shows what the exposure actually is.

Frequently asked questions

Is there an official IRS form for a Form 5472 penalty abatement letter?
No. There is no official IRS form for a reasonable-cause request on a Form 5472 penalty. You write a letter. Form 843 exists for refund claims and certain abatement requests, and it is sometimes used alongside a reasonable-cause statement, but the substance of the request is always the written explanation you attach.
Where do I send the Form 5472 penalty abatement letter?
If you received a notice, send the letter to the address printed on that notice — that routes it to the unit holding your case. If you have not received a notice and are filing a delinquent return voluntarily, attach the reasonable-cause statement to the Form 5472 package and send it to Internal Revenue Service, 1973 Rulon White Blvd., M/S 6112, Attn: PIN Unit, Ogden, UT 84201.
What makes a reasonable-cause letter more likely to be accepted?
Specific dates, a single clear reason rather than several weak ones, documentary evidence attached, and proof that you corrected the failure as soon as you discovered it. The IRS weighs whether you exercised ordinary business care and prudence. Vague statements of hardship without dates or documents are the most common reason a request fails.
Does not knowing about Form 5472 count as reasonable cause?
Ignorance of the law on its own is generally not reasonable cause. It can contribute when combined with other facts — that you are a non-resident with no US filing history, that the rule is a narrow 2017 provision, that you relied on a service engaged for compliance, and that you corrected the failure immediately on discovering it. The combination is what carries weight, not the ignorance alone.
Should I file the late Form 5472 before or with the abatement letter?
File the delinquent Form 5472 with the letter, or before it. A request for relief with the return still unfiled is very unlikely to succeed, because the continuation penalty keeps accruing while the form is outstanding. Filing voluntarily before the IRS contacts you gives the strongest position.
Does first-time penalty abatement apply to the Form 5472 penalty?
Its application to section 6038A information-return penalties is limited and fact-specific, so it should not be assumed. Reasonable cause is the primary route for a Form 5472 penalty. Do not build a request around first-time abatement without confirming it applies to your situation.
Does form5472.tax write or submit the abatement letter for me?
No. form5472.tax prepares and files Form 5472 and the pro forma Form 1120 for a flat $299, and can include a reasonable-cause statement with a delinquent filing. We do not represent clients before the IRS and do not argue abatement requests on your behalf. Representation requires a licensed CPA, enrolled agent, or tax attorney.
How long does the IRS take to respond?
Expect six to twelve months, and sometimes longer for international filers. If the request is denied you may ask the IRS Independent Office of Appeals to review it, within the deadline stated on the denial letter. An appeal should be handled by a licensed representative.
