Form 5472 (2026): The $25,000 Mistake Foreign-Owned LLCs Make + AI Agent Skill

Form 5472 is the IRS information return that a foreign-owned US company files to report money moving between the company and its foreign owner, and missing it triggers an automatic $25,000 penalty under IRC §6038A. Since 2017 the requirement covers foreign-owned single-member LLCs, which means virtually every non-US resident with a US LLC must file it yearly, attached to a pro-forma Form 1120, even when the LLC owes zero US tax and earned nothing.

Who Must File Form 5472

Two groups must file Form 5472, Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business:

1. US corporations that are at least 25% foreign-owned. A foreign person is a 25% foreign shareholder when they own, directly or indirectly, at least 25% of the corporation's voting power or stock value.
2. Foreign-owned US disregarded entities (DEs). A single-member US LLC wholly owned by one foreign person is a disregarded entity, and Treasury regulations (T.D. 9796, effective for tax years starting in 2017) treat it as a domestic corporation solely for this reporting requirement.

That second category is the trap. A disregarded LLC files no income tax return of its own, so owners assume no IRS paperwork exists. Form 5472 is the exception: if the LLC had any reportable transaction with its foreign owner or another related party during the year, the filing is mandatory. "Related party" reaches beyond the owner to anyone related to the owner or the entity under IRC §§267(b), 707(b)(1), or 482, so payments to the owner's other companies count too.

A foreign-owned multi-member LLC is outside this regime; it is a partnership that files Form 1065 with its own reporting rules. And the LLC needs an EIN before it can file anything; foreign owners get one with no SSN via Form SS-4.

A 30-Second Filing Check

The Form 5472 Penalty Is $25,000, and It Is Automatic

Under IRC §6038A(d), a reporting corporation that fails to file Form 5472 when due, or files it substantially incomplete, is assessed a $25,000 penalty per form. No IRS agent weighs your intentions; the assessment is systemic, usually arriving as a CP215 notice. Filing a sloppy form counts as not filing: the instructions state that a substantially incomplete Form 5472 constitutes a failure.

The meter then keeps running. If the failure continues more than 90 days after the IRS notifies you, an additional $25,000 accrues for each 30-day period (or part of one) that follows, per related party. A single forgotten filing discovered late can stack into six figures. For scale: the LLC that owes this penalty typically owed $0 in actual US tax.

How a Disregarded LLC Files: The Pro-Forma 1120 Wrapper

A disregarded LLC cannot file Form 5472 on its own; the form must ride on a Form 1120 "wrapper," and the wrapper follows special rules from the official instructions:

1. Prepare Form 1120 with only the LLC's name, address, and items B and E filled in. Nothing else on the 1120 applies; it is a cover page, not a tax return.
2. Write "Foreign-owned U.S. DE" across the top of the Form 1120.
3. Attach the completed Form 5472.
4. File by fax or mail (addresses below). The pro-forma package cannot be e-filed through standard software.

The reporting period is the owner's US tax year; for an individual owner with no other US filings, that is the calendar year, making the deadline April 15 of the following year.

What Counts as a Reportable Transaction

For a foreign-owned disregarded LLC, essentially every dollar that moves between the LLC and its owner is reportable, including the money that created the company. The instructions require DEs to report amounts "paid or received in connection with the formation, dissolution, acquisition, and disposition of the entity, including contributions to, and distributions from, the entity" (Part V), on top of the standard related-party items such as rent, royalties, interest, and service fees (Part IV).

Strictly, an LLC with no reportable transactions in a year has no Form 5472 obligation for that year. In practice that year rarely exists: someone pays the registered agent, and someone funded the formation. Assume you file every year and you will never be wrong by $25,000.

When Form 5472 Is Due and How to Extend

Form 5472 is due April 15 for a calendar-year owner, together with the pro-forma Form 1120. To get six extra months, file Form 7004 by April 15:

• Write "Foreign-owned U.S. DE" across the top of the Form 7004
• Enter the code for Form 1120 in Part I, line 1
• Send it by fax or mail to the same dedicated unit below

A timely Form 7004 moves the deadline to October 15. The extension extends paperwork, not any tax, and for a no-tax disregarded entity there is nothing to prepay; the extension is purely protective.

Where to File: Fax or Mail Only

Foreign-owned disregarded LLCs send the pro-forma 1120 with Form 5472 attached to a dedicated IRS unit, per the December 2024 instructions:

• Fax: 855-887-7737 (transmit at 300 DPI or higher)
• Mail: Internal Revenue Service, 1973 Rulon White Blvd., M/S 6112, Attn: PIN Unit, Ogden, Utah 84201

Fax wins on proof: keep the transmission confirmation with your records, because "we never received it" plus an automatic penalty is an argument you want documents for. Do not mail the package to the regular Form 1120 processing addresses; the dedicated unit exists precisely because these filings otherwise get lost as "empty" corporate returns.

Missed a Year? The Penalty Abatement Path

The $25,000 penalty can be removed for reasonable cause: you must show you exercised ordinary business care and still could not comply. When a CP215 notice arrives, respond in writing with a reasonable-cause statement covering what happened, why it was outside your control, and how you fixed it (file the late Form 5472 at the same time if you have not). Facts that help: this was the first year of the requirement for you, you relied on a professional who missed it, records were unavailable for reasons you can document, and you filed promptly once you learned of the duty.

Two realistic warnings. First-time abatement, the near-automatic relief that clears many late-filing penalties, is generally not available for §6038A information-return penalties; reasonable cause is the standard you must actually meet. Second, "I didn't know" alone rarely succeeds, but "I acted the moment I learned, and here is the filing" often does. The full mechanics of penalty-relief requests, including when a paid penalty is recovered with Form 843, are in our Form 843 penalty abatement guide.

What Form 5472 Is NOT

• Form 5472 is not a tax payment; it is an information return, and filing it creates no US tax liability by itself.
• Form 5472 is not an income tax return; whether the owner owes US tax is a separate question of effectively connected income, covered in our US LLC for non-residents guide.
• Form 5472 is not required of foreign-owned multi-member LLCs; partnerships have their own filing regime on Form 1065.
• Form 5472 is not satisfied by your home-country filings; reporting the LLC to your local tax authority does nothing for §6038A.
• Form 5472 is not a one-time filing; the obligation repeats every year there is a reportable transaction, including the dissolution year.

A Worked Example: One Year, Three Reportable Transactions

Amara, a software consultant in Lagos, forms a Wyoming LLC in February 2026. During 2026 she wires the LLC $1,500 to fund its account, pays the $99 registered agent invoice from her personal card, and takes a $4,000 owner draw in November. Her LLC earns $28,000 from US clients, all work performed in Nigeria, so she has no effectively connected income and no US income tax.

Her tax-year-2026 filing, due April 15, 2027: a Form 1120 with "Foreign-owned U.S. DE" across the top and only name, address, and items B and E completed, plus Form 5472 reporting the $1,599 of contributions and the $4,000 distribution in Part V. She faxes the package to 855-887-7737 and saves the confirmation page. Total US tax paid: $0. Penalty exposure if she had skipped it: $25,000, growing $25,000 per month once 90 days passed after an IRS notice.

Common Mistakes Foreign-Owned LLCs Make

Treating "no income, no tax" as "no filing." The obligation is triggered by related-party transactions, not by profit. A dormant LLC whose owner paid one state fee still has a reportable transaction.

E-filing or mailing to the regular 1120 address. The pro-forma package must go to the dedicated Ogden unit by fax or mail; standard e-file channels will not carry a DE's wrapper return.

Reporting the draw but not the contribution. Part V explicitly covers both directions, including formation funding. A form showing only distributions is substantially incomplete, which the IRS treats as not filed.

Skipping the final year. Dissolving the LLC creates reportable dissolution amounts; the year you shut down is a filing year, not an exempt one.

Forgetting the 7004 label. An extension request without "Foreign-owned U.S. DE" written across the top can be processed as a regular corporate extension, leaving no record tied to your pro-forma filing.

File Form 5472 With an AI Agent Skill

Our open-source skill library at github.com/jupid-tax/jupid-skills includes a dedicated forms/form-5472 skill that teaches AI assistants like Claude to work the filing end to end: it asks who owns the LLC, builds the reportable-transaction list from your records (contributions, personally paid expenses, draws), checks the parts of the form that apply to a disregarded entity, and assembles the pro-forma 1120 wrapper with the correct top label, deadline, and fax number. You review the completed package against your bank statements before sending it.
