Form 5472 Instructions: How to Complete Each Part Without Triggering the Penalty

Quick answer: Form 5472 has eight parts, but most filers complete four: Part I (your entity), Part II (the 25% foreign shareholder), Part III (the related party), and Part IV, V or VI depending on the transaction type. The detail that catches people out is Line 1g — you file a separate Form 5472 for every related party you had reportable transactions with, not one form covering all of them.

This walks through what each part is asking for and where filers go wrong. It assumes you already know you have a filing obligation — if you are not sure, start with our guide to who must file Form 5472 and the $25,000 penalty.

Everything below reflects the current IRS instructions. Verify against the current revision before filing, because this form has changed several times.

One form per related party

Start here, because it changes the size of the job and the size of the risk.

Line 1g asks for the total number of Forms 5472 being filed for the year. That is because you file a separate form for each foreign or U.S. person that is a related party with which you had a reportable transaction. Three related parties means three Forms 5472.

The consequence is arithmetic. The $25,000 penalty attaches per form. Missing three related parties is not a $25,000 exposure — it is $75,000, in that year alone.

Part I — Reporting Corporation

Identifying information about your entity, plus four lines that do real work:

• Line 1c — total assets. Domestic filers take this from Form 1120, page 1, item D. Foreign reporting corporations take it from Form 1120-F, Schedule L, line 17, column (d).
• Line 1f — total transaction value on this form. The sum of Part IV lines 22 and 36, plus the fair market value of anything reported in Part VI (and Part V for a disregarded entity). Leave it blank if the reportable transaction is with a U.S. related party.
• Line 1h — total across all forms. The sum of every Line 1f on every Form 5472 you are filing this year. These two lines are frequently transposed.
• Line 1o — principal countries of business. “Worldwide” is not an acceptable entry, and you exclude countries where you operate solely through a subsidiary.

Line 1j flags a first-time filer. Line 3 is the box a foreign-owned U.S. disregarded entity checks — miss it and the IRS does not know which regime you are in.

Part II — 25% Foreign Shareholder

Completed by 25% foreign-owned U.S. corporations, including foreign-owned disregarded entities. If you are a disregarded entity, report your foreign owner on the lines provided for the 25% foreign shareholder.

The form has room for two direct and two ultimate indirect shareholders, ordered by percentage owned. More than that goes on an attached sheet.

Identifying numbers — the sequence matters

Each shareholder needs a U.S. identifying number if they have one: an SSN or ITIN for individuals, an EIN for entities. If there is no U.S. number, you must supply a reference ID number instead.

Reference ID numbers are assigned by you, not the IRS — there is nothing to apply for. Requirements: alphanumeric only, no spaces or special characters, maximum 50 characters. Critically, the same number must be used consistently year to year for that person, and a retired number can never be reused for someone else.

A foreign-owned U.S. disregarded entity must also enter a foreign taxpayer identification number for each direct and ultimate foreign owner. If there genuinely is none, enter “None” or “N/A” rather than leaving it blank.

For indirect ownership reported on lines 6 and 7, you must attach an explanation of the attribution of ownership. This is where the Section 318 analysis gets written down, and it is routinely skipped.

Part III — Related Party

Every filer completes Part III — including when the related party is the same person already identified in Part II as your 25% foreign shareholder. Filers often leave it blank on the logic that they already gave that information. That is an incomplete form.

Same identifying-number rules apply: U.S. number if available, reference ID number if not.

Part IV — Monetary transactions with a foreign related party

The main reporting grid: amounts received on one side, amounts paid on the other, across sales, rents, royalties, commissions, interest, borrowings and loans.

Do not complete Part IV for transactions with a domestic related party. Those trigger the filing obligation but are not itemized here.

Rules worth knowing before you start:

• Accrual filers use accrued amounts, not cash movements. “Paid” and “received” include accruals.
• Report in U.S. dollars and attach a schedule showing the exchange rates used. The attachment is required, not optional.
• Reasonable estimates are permitted where actual amounts are not determinable — defined as an amount between 75% and 125% of the actual figure.
• Small amounts. If a transaction or series of transactions with a foreign related party totals $50,000 or less, you may report it as “$50,000 or less.”
• Borrowed and loaned amounts (lines 17 and 31) use either the outstanding balance method or the monthly average method — including balances already in place at the start of the year.
• Interest paid (line 32) is reported net of any Section 163(j) limitation. Amounts disallowed this year get reported in the later year they become deductible.

Part V — The disregarded entity catch-all

Short, easy to overlook, and the reason many “I had no transactions” conclusions are wrong.

A foreign-owned U.S. disregarded entity checks the Part V box if it had any other transaction not already captured in Part IV. The instructions specifically include amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity — including contributions to it and distributions from it. These are described on an attached statement.

So: funding your LLC is reportable. Taking money out is reportable. Paying its formation costs from your personal account is reportable. An LLC that did no business at all can still have a Part V disclosure.

Part VI — Nonmonetary and less-than-full-consideration transactions

For anything not settled purely in money — property transfers, services rendered, bargain transactions. Not used for domestic related parties.

Part VI requires an attached schedule with enough detail to determine the nature and approximate value of each transaction, specifically covering property, rights or obligations moving in each direction, services performed in each direction, and a reasonable estimate of fair market value or another reasonable indicator of value.

This is narrative disclosure, not a number in a box, and a thin description is a weak spot if the return is examined.

Parts VII and VIII

Part VII covers additional information required of certain filers. Part VIII covers cost sharing arrangements — complete one Part VIII per arrangement and report the count on Line 1k. Most small foreign-owned LLCs never touch either.

The mistakes that cost the most

• Filing one form for multiple related parties. One per related party. This multiplies the penalty.
• Skipping Part III because the party appears in Part II. All filers complete Part III.
• Concluding there were no transactions without reading Part V. Contributions and distributions count.
• Omitting the exchange rate schedule on foreign currency amounts.
• Omitting the attribution explanation for indirect ownership.
• Inventing a new reference ID number each year. Consistency is mandatory.
• Leaving the FTIN blank as a disregarded entity instead of entering “None.”

Each of these produces an incomplete return — and a substantially incomplete Form 5472 is treated as a failure to file, carrying the full penalty. There is no partial credit.

Frequently asked questions

Do I file one form or several?

One per related party with which you had reportable transactions. Report the total count on Line 1g.

What if I do not know the exact amounts?

Reasonable estimates are allowed where actual amounts are not determinable — meaning within 75% to 125% of the actual figure. That is a tolerance for genuine uncertainty, not permission to guess.

My related party has no U.S. tax ID. What do I enter?

Assign a reference ID number yourself — alphanumeric, no spaces, 50 characters or fewer — and use the same one every year.

Do transactions with a U.S. related party get itemized?

No. They can trigger the filing requirement and require Part III, but Parts IV, V and VI are not used to specifically identify transactions with a U.S. related party.

Is Form 5472 the same as Form 5471?

No, and they run in opposite directions. Form 5471 is filed by U.S. persons who own interests in foreign corporations. Form 5472 is filed by U.S. entities that are foreign-owned, or by foreign corporations doing business in the U.S. If you are a foreign owner of a U.S. LLC, 5472 is your form.

Before you file

The form is the last step, not the first. The work that determines whether it is correct happens before anything gets filled in: identifying every related party under the attribution rules, capturing every reportable transaction including the non-obvious ones, and supporting the amounts.

We prepare Form 5472 filings for foreign-owned U.S. entities nationwide, including prior-year exposure reviews. Schedule a consultation.

General information current as of publication, not tax advice. Confirm against the current form instructions before filing.

If you own a U.S. entity as a foreign person, the filing is downstream of the bookkeeping. See how we structure the books to support it on our foreign-owned U.S. business accounting page.

If the underlying books are wrong all year, the pro forma return becomes far harder to prepare correctly — see the pro forma Form 1120 for a foreign-owned LLC and who has to file and what the penalty is.

If a filing was already missed, the $25,000 penalty is assessed per form per year and it is systemically issued rather than discretionary. That does not make it final — reasonable cause relief is available and the argument has to be built carefully, which we cover in Form 5472 penalty abatement.

Form 5472 is only as accurate as the ledger behind it. A foreign-owned entity with no US finance staff is usually the one that discovers in March that related-party transactions were never tracked separately all year — which is the case for putting the monthly function in place through outsourced accounting rather than reconstructing it at filing time.
