Quick answer: Form 5472 is an information return that reports transactions between a U.S. business and its foreign owner or related parties. It applies to U.S. corporations at least 25% foreign-owned, foreign corporations doing business in the U.S., and — the group most often caught off guard — U.S. LLCs wholly owned by a foreign person. The penalty for not filing is $25,000, and it applies per year.

If you own a U.S. LLC and you are not a U.S. person, there is a good chance you have a filing obligation you have never heard of — and that the penalty has been accruing quietly for several years.

The most common version of this: someone forms a single-member LLC in Delaware, Wyoming or Florida, uses it to hold a bank account or import goods, has no U.S. income tax return to file, and reasonably concludes there is nothing to file at all. That conclusion is wrong, and it is expensive.

What Form 5472 actually is

It is an information return, not a tax return. It calculates no tax and produces no bill. Its job is to show the IRS what money moved between a U.S. business and the foreign people or companies connected to it.

The authority is IRC Section 6038A and Section 6038C. Congress wanted visibility into cross-border related-party dealings, because that is where profit gets shifted out of the U.S. tax base.

Important consequence: because it produces no tax, people assume it is optional or low-stakes. The penalty structure says otherwise.

Who has to file

Per the IRS instructions, a “reporting corporation” is either:

A 25% foreign-owned U.S. corporation — meaning at least one direct or indirect 25% foreign shareholder at any time during the tax year, measured by vote or value; or
A foreign corporation engaged in a trade or business within the United States.

A reporting corporation must file if it had a reportable transaction with a foreign or domestic related party during the year.

The single-member LLC rule that catches everyone

For tax years beginning on or after January 1, 2017, a U.S. disregarded entity wholly owned by a foreign person is treated as a separate entity and classified as a corporation for the limited purposes of Section 6038A.

Read that carefully. The LLC is still disregarded for income tax. It is still not paying U.S. corporate tax. But it is now a reporting corporation for this one purpose, and it must file.

This is why the obligation is invisible to so many owners. Nothing about their income tax position changed. Only the information reporting did.

The penalty is per form, per year, and it compounds if it is not fixed

Failures do not sit still. An unfiled year stays open, the statute does not start running, and a second notice can follow the first. The path back is reasonable cause, which depends almost entirely on the quality of the records you can produce for the years in question.

Where it gets genuinely difficult

The form itself is short. Determining what belongs on it is not. Three areas cause most of the failures we see, and they are the reason this is not a do-it-yourself filing.

1. Who counts as a “related party”

A related party includes any direct or indirect 25% foreign shareholder, any person related to the reporting corporation under Section 267(b) or 707(b)(1), any person related to a 25% foreign shareholder, and any person related under Section 482.

Layered on top are the constructive ownership rules of Section 318, applied with statutory modifications specific to this form. Ownership is attributed through family members, partnerships, estates, trusts and corporations. Someone who owns nothing directly can be a 25% shareholder by attribution.

This is where an owner working from the form alone reliably goes wrong. The related parties are frequently not the obvious ones, and attribution is not intuitive.

2. What counts as a reportable transaction

Part IV captures monetary transactions — sales, rents, royalties, interest, amounts borrowed and loaned, and more. Part VI captures nonmonetary transactions and those made for less than full consideration, which require an attached narrative schedule describing the property or services exchanged and a reasonable estimate of fair market value.

For a foreign-owned disregarded entity, Part V goes further than most people expect. It reaches “any other transaction,” expressly including amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity — including contributions to and distributions from it.

That last point deserves emphasis. Funding your own LLC is a reportable transaction. Taking money back out is a reportable transaction. An owner who concludes “I had no transactions” because the LLC did no business has usually already had two.

3. Pricing what moved

Where the U.S. entity buys goods or services from its foreign parent, the amounts reported have to reflect arm’s-length pricing under Section 482. For importers this is doubly sensitive, because the price declared to U.S. Customs and the transfer price reported to the IRS are examined by two different agencies with different incentives. Inconsistency between them is a problem in both directions.

The filing mechanics are unusual

For a normal reporting corporation, Form 5472 is attached to the income tax return and due with it, including extensions.

For a foreign-owned U.S. disregarded entity — the most common case — the process is genuinely strange:

The DE files a pro forma Form 1120 with Form 5472 attached. Only the name and address and two specific items on page 1 are completed. It is not a real corporate return.
The DE uses the same tax year as its owner, or the calendar year if the owner has none.
It cannot be filed electronically. The IRS requires fax or mail to a dedicated address that is different from the normal Form 1120 address.
An extension is requested on Form 7004 using the Form 1120 code, sent to that same dedicated address by the regular due date.

The no-e-file rule matters more than it sounds. Consumer tax software will not produce this filing, and sending it to the standard Form 1120 address is a common way for a timely filing to be treated as never made.

The penalty

$25,000 is assessed on a reporting corporation that fails to file when due and in the manner prescribed. The same $25,000 applies for failure to maintain the records required under the regulations — a separate obligation from filing.

Three features make this worse than a typical late-filing penalty:

A substantially incomplete Form 5472 is treated as a failure to file. Filing something wrong is not partial credit. It can carry the full penalty.
It compounds. If the failure continues more than 90 days after IRS notification, an additional $25,000 applies per related party for each 30-day period the failure continues.
It repeats annually. Each unfiled year is its own penalty. Four missed years is not a $25,000 problem.

Criminal penalties can also apply for failure to submit information or for filing false information.

A worked scenario

A resident of Spain forms a Florida single-member LLC in 2022 to import and resell equipment. He wires $150,000 from personal funds to capitalize it, buys inventory from a company his brother controls, and withdraws $40,000 in 2024. He files no U.S. returns because the LLC has no U.S. income tax filing requirement.

What he actually has: a Form 5472 obligation for each year from 2022 forward. The capital contribution and the distribution are reportable. The purchases from his brother’s company are reportable, and the brother is a related party by attribution — not because he owns the LLC, but because of who he is related to. The pricing on those purchases needs to be defensible under Section 482, and it needs to be consistent with what was declared at the border.

Three unfiled years, each carrying a $25,000 exposure, plus a record-maintenance question. This is a common fact pattern, not an extreme one.

If you are already behind

Most people who discover this obligation discover it late. That is a solvable situation, but the sequence matters and the wrong first move can make it worse.

What we would not advise: quietly filing the current year and hoping the prior years go unnoticed, or submitting several years at once with no supporting narrative. Both leave the reasonable-cause question unaddressed, and the second can accelerate assessment.

Delinquent international information returns are handled through specific procedures, and eligibility depends on facts including whether the IRS has already contacted you and whether there is unreported income involved. That assessment should happen before anything is submitted — not after.

Frequently asked questions

My LLC had no income. Do I still file?

Very possibly. The trigger is a reportable transaction, not income. Funding the LLC or taking money out are themselves reportable transactions for a foreign-owned disregarded entity, so an LLC that never earned a dollar can still have an obligation.

Is there any situation where I do not have to file?

Yes — there are specific exceptions, the most relevant being that no filing is required if there were no reportable transactions of the listed types. Several other exceptions exist but expressly do not apply to foreign-owned disregarded entities. Whether you fit one is a facts question worth confirming rather than assuming.

Can I e-file it?

Not if you are a foreign-owned U.S. disregarded entity. The IRS requires fax or mail to a dedicated address. Other reporting corporations attach it to an income tax return that may be filed electronically.

Do I need a U.S. tax ID?

The entity needs an EIN in order to file. Obtaining one for a foreign-owned entity with no U.S. responsible party with a Social Security number takes longer than most owners expect, so it should be started early relative to the deadline.

What if I file it myself and get it wrong?

A substantially incomplete Form 5472 is treated as a failure to file. There is no reduced penalty for a good-faith attempt that misses required transactions or related parties, which is why the related-party and reportable-transaction analysis matters more than the form.

Where we help

Precision Accounting & Consulting works with foreign-owned U.S. entities and importers nationwide. On Form 5472 engagements that means determining who your related parties actually are under the attribution rules, identifying and pricing every reportable transaction, preparing and filing the return correctly for your entity type, assessing exposure on any prior years, and putting the required records in place so the separate record-maintenance penalty does not apply.

If you own a U.S. entity and you are not a U.S. person — or you advise someone who does — a short review is worth far less than one year of penalty. Schedule a consultation.
