Form 5472 Penalty: The $25,000 Risk for Foreign-Owned LLCs

TL;DR

The Form 5472 penalty is a minimum of $25,000 per return for any foreign-owned U.S. LLC that fails to file Form 5472 (with a pro forma Form 1120) on time, completely, and accurately. It applies even to LLCs with zero income, and it grows by another $25,000 for each 30-day period the failure continues after IRS notice.

What is the penalty for not filing Form 5472?

The penalty for failing to file Form 5472 is $25,000 per required return, assessed under Internal Revenue Code §6038A(d). The same $25,000 applies whether you filed nothing, filed late, or filed a return that was substantially incomplete or inaccurate.

This is a flat statutory penalty, not a percentage of tax owed. Because a foreign-owned single-member LLC often owes no U.S. income tax at all, the penalty is unrelated to profit — a company that earned nothing can still be assessed the full $25,000.

The amount was raised from $10,000 to $25,000 by the Tax Cuts and Jobs Act, effective for tax years beginning after December 31, 2017. Every open year since then carries the higher figure.

Does the penalty apply to a foreign-owned LLC with no income?

Yes — even with no income. The obligation is triggered by reportable transactions, not by revenue or profit. Forming the LLC, contributing capital, paying a registered agent, and moving money between the owner and the company all count as reportable transactions.

Since 2017, U.S. Treasury regulations treat a foreign-owned domestic disregarded entity as a corporation for the limited purpose of §6038A reporting. In plain terms: a non-U.S. person’s single-member LLC must file Form 5472 with a pro forma Form 1120 even if it never made a sale. A dormant LLC that only paid a state fee has already had a reportable transaction.

How does the continuation penalty work?

The initial $25,000 is only the starting point. If the failure continues after the IRS mails a formal notice, an additional $25,000 applies for each 30-day period (or fraction of a period) that the return remains unfiled, beginning 90 days after that notice.

There is no stated cap on the continuation penalty in the statute. In practice this means an ignored notice can multiply a single missed form into six figures over a matter of months.

What the Form 5472 penalty is NOT

Understanding what this penalty is not prevents costly misreadings:

• It is not a tax. Form 5472 is an information return. The $25,000 is a penalty for non-disclosure, separate from any income tax your LLC may or may not owe.
• It is not the FBAR penalty. FBAR (FinCEN Form 114) applies to U.S. persons with foreign accounts. Form 5472 applies to foreign owners of U.S. entities. Different form, different filer, different rules.
• It is not the Form 5471 penalty. Form 5471 covers U.S. persons who own foreign corporations. Form 5472 covers foreign owners of U.S. entities. They share a penalty structure under related code sections but apply to opposite fact patterns.
• It is not waived by having no revenue. A common and expensive myth. Zero income does not remove the filing duty.
• It is not automatically forgiven for first-time filers. Unlike some late-filing penalties, the §6038A penalty generally does not qualify for the IRS First-Time Abate program; relief usually depends on reasonable cause.

Who has to file Form 5472?

A U.S. business must file Form 5472 if it is a reporting corporation — which, for this audience, means either of the following:

1. A U.S. corporation that is at least 25% foreign-owned, or
2. A foreign-owned U.S. disregarded entity (most commonly a single-member LLC owned by a non-U.S. person).

If your LLC is owned by a non-U.S. individual or a non-U.S. company and had any reportable transaction during the year, you are within scope. Ownership of 25% or more by one foreign person is the threshold.

How do I avoid the Form 5472 penalty?

Avoiding the penalty comes down to filing a complete, accurate return by the deadline. Use this checklist:

1. Confirm you have an EIN. The LLC needs an Employer Identification Number to file. A non-resident owner without an SSN can still obtain one.
2. Identify every reportable transaction. Include formation costs, capital contributions, loans, and any payments between the LLC and its owner or related parties.
3. Prepare Form 5472 with a pro forma Form 1120. For a disregarded entity, the 5472 is attached to a bare “pro forma” 1120 marked accordingly.
4. File by the deadline. For a calendar-year LLC, the due date is April 15, with a six-month extension to October 15 available via Form 7004 if requested on time (full deadline calendar).
5. Submit by mail or fax to the IRS. A foreign-owned disregarded entity’s 5472/1120 package is filed by mail or fax to the IRS service center in Ogden, Utah — it is not part of standard e-file.
6. Keep records for the audit window. Retain the underlying documents that support each reportable transaction.

What if I already missed the deadline?

If you have unfiled Form 5472s, filing them promptly — before the IRS contacts you — is generally the strongest position (step-by-step late-filing guide here). Two facts matter most:

First, the continuation penalty only escalates after an IRS notice, so acting before that notice limits exposure. Second, the §6038A penalty can be abated for reasonable cause — a demonstration that you exercised ordinary business care and prudence but still could not file on time.

Reasonable cause is fact-specific and never guaranteed. The IRS evaluates the full circumstances, and courts and the IRS have both clarified that a bare claim of ignorance is usually insufficient. Because a delinquent filing can invite scrutiny, many foreign owners have these years prepared and reviewed by a licensed U.S. tax preparer rather than filing blind. Our Form 5472 filing service handles current and prior years at a flat published price.
