The Form 5472 penalty: $25,000, per form, per year

Where the $25,000 comes from

The penalty sits in the Internal Revenue Code, at section 6038A(d) for reporting corporations with 25% foreign shareholders and at section 6038C for foreign corporations engaged in a US trade or business. It applies when a reporting corporation fails to furnish the required information — that is, fails to file a substantially complete Form 5472 by the due date of the return it belongs to, including any extension properly obtained.

Two features of that wording matter a great deal in practice, and both catch people out:

• The penalty is not tied to tax. There is no requirement that any tax was underpaid, or that any tax was due at all. Form 5472 is an information return. The failure being penalised is the failure to inform.
• The amount is fixed, not proportional. A dormant LLC whose only reportable transaction was a $300 capital contribution faces the same statutory amount as an entity that moved millions. There is no de minimis threshold in the statute.

How it multiplies

Understanding the multiplication is the difference between a manageable problem and a shocking one. The penalty applies to each failure, and a failure is one required form for one entity for one tax year.

Swipe the table sideways to see all columns

Founders who form a US LLC for payment access, never learn about Form 5472, and discover it three years later are the most common version of this. They are also usually the ones with the least activity to report — which makes the arithmetic feel especially unfair, and makes the reasonable cause discussion below the important part of this page.

Continuation penalties after notice

The initial amount is not the ceiling. Where the IRS mails a notice of the failure to the reporting corporation, and the failure continues, an additional statutory amount applies for each 30-day period, or fraction of a 30-day period, during which the failure continues after a 90-day grace window following that notice.

The statute does not state a maximum for these continuation amounts. In principle the figure keeps growing while the failure persists. This is the mechanism that turns a serious problem into an unmanageable one, and it is why responding promptly to any IRS correspondence about Form 5472 matters more than getting the response perfect.

An incomplete form can count as unfiled

The statute penalises the failure to furnish a substantially complete return. A Form 5472 that arrives on time but omits required information can be treated as not having been filed, which puts the same statutory amount into play.

The omissions that most often cause this on foreign-owned LLC filings:

• No reference ID number for the foreign owner. Where the owner has no US identifying number, the instructions require a reference ID — a code you create and reuse each year. Leaving both blank leaves a required field empty.
• Blank transaction parts. Leaving the reportable-transaction part empty rather than entering the amounts, including zeros where appropriate.
• Missing the pro forma Form 1120 cover. A foreign-owned disregarded entity's Form 5472 is attached to a pro forma Form 1120; sent alone it may not be processed as a filing at all.
• No signature. An unsigned return can be treated as never filed.
• Missing the required notation. The instructions direct that FOREIGN-OWNED U.S. DE be written across the top of the pro forma Form 1120.

None of these are difficult to get right — they are simply easy to not know about. The line-by-line instructions page walks through each part, and the generator fills these fields for you from your answers.

Reasonable cause — the part that actually helps

The penalty does not apply where the failure to file was due to reasonable cause and not wilful neglect. This is the relief that matters, and it is worth understanding properly rather than hoping for.

Reasonable cause is a facts-and-circumstances test. The essential question is whether the taxpayer exercised ordinary business care and prudence and was nonetheless unable to comply. It is claimed by an affirmative written statement setting out all the facts the taxpayer relies on, signed under penalties of perjury.

What a reasonable-cause statement typically contains

There is no official template, and the content should be shaped to your facts by someone qualified. In general a statement covers:

1. Who is making the statement — the entity, its EIN, the tax years concerned and the forms involved.
2. What happened, chronologically — when the entity was formed, why, what it did, and what the owner understood about their obligations at each point.
3. Why the obligation was not met — the specific circumstances, not general assertions of ignorance.
4. What was relied on — if a professional or service provider was engaged, who they were, what they were told and what they advised.
5. When and how the failure was discovered — and how quickly action followed.
6. What has been done to fix it — the late filings enclosed, and the systems now in place to prevent recurrence.
7. The perjury declaration and signature.

Two points of tone are worth noting. Brevity and specificity read better than length and emotion. And a statement that quietly acknowledges what the taxpayer got wrong, while explaining why they nonetheless acted with ordinary care, is more credible than one that accepts nothing.

This is the highest-value place to spend money on a professional. A well-drafted statement can determine whether the statutory amount is asserted at all. That is a far better use of a few hundred dollars than having someone type a form you could complete yourself.

Why leaving it unfiled is the worst of the options

People sometimes reason that an unfiled form is invisible, and that filing late draws attention to a problem the IRS might never notice. Three things make that reasoning weak.

1. The assessment period may not be running. Failing to file certain required information returns can keep the limitations period open for the related tax year — potentially indefinitely, until the required information is furnished. Not filing does not start a clock ticking in your favour; it can stop one that would otherwise have run.
2. You are less invisible than you think. US banks and payment processors report, EIN records exist, state registries are public, and international information-exchange arrangements are extensive. The entity's existence is not a secret.
3. Voluntary correction is treated differently from discovery. Coming forward before the IRS raises the issue is a materially different posture — for the reasonable-cause analysis and for the continuation-penalty clock — than being found.

What to do if you are already late

1. Establish which years are actually affected

   For each tax year since formation, ask whether the entity was in the filing category and whether a reportable transaction occurred. The free check helps you work through one year at a time.

2. Gather the records for each of those years

   Bank and payment-processor statements, formation invoices, registered-agent charges, and any transfer between you and the entity.

3. Decide how you will present the filings

   For a single recent year, filing promptly is often straightforward. For two or more years, or where any notice has been received, get professional input on presentation before sending anything.

4. Prepare a complete package per year

   One Form 5472 with its pro forma Form 1120 cover for each year, each signed, with a reasonable-cause statement where the facts support one.

5. File with proof and keep copies

   Use a tracked service, keep the receipt or fax confirmation, and store a full copy of everything you sent.

6. Put next year on a calendar

   The obligation recurs annually. Most repeat failures happen because nobody diarised it.
