Form 5472 runs in the opposite direction from most of the international information returns. Form 5471, Form 8865, and Form 8858 are outbound — they report a US person's interest in a foreign corporation, partnership, or disregarded entity. Form 5472 is inbound: it reports the dealings between a US-connected company and the foreign owners or affiliates on the other side of those dealings. It computes no tax. But it is one of the most expensive information returns to miss — under §6038A(d) the penalty is $25,000 per form, with an uncapped additional $25,000 for each 30-day period the failure continues after a 90-day IRS notice period, and under §6501(c)(8) the assessment statute of limitations does not begin to run until the information is furnished. That $25,000 is more than double the $10,000 penalty on the §6038 outbound forms — a number not to carry across by reflex.
This guide is about the threshold question that precedes the form's parts and schedules: is this company a "reporting corporation," did it have a "reportable transaction" with a "related party" during the year, and does any exception apply? Form 5472 has no filer-category system — nothing here resembles the five categories of Form 5471. The structure is simpler to state and easier to miss: identify the type of reporting corporation, then test the transaction gate. We work it in that order, then take up the trap that catches the most filers — the foreign-owned US LLC.
In plain terms two questions decide Form 5472. First, is the company one of three kinds of "reporting corporation" — a US corporation that is at least 25% foreign-owned, a foreign corporation doing business in the US, or a US entity (often an LLC) wholly owned by a foreign person and otherwise ignored for income tax? Second — and this is the part that gets missed — did it actually have a dealing with a related party during the year? Being foreign-owned is not enough on its own. PILOT determines whether a Form 5472 obligation exists for each company in a structure, and for which related parties.
The building blocks
Form 5472 is built from three defined terms — a reporting corporation, a related party, and a reportable transaction. Pin all three down and the obligation falls out: the first decides whether the form is in play at all, and the second and third decide whether it is actually due.
The three reporting corporations
A "reporting corporation" is one of three things (Reg §1.6038A-1(c)(1)):
| Reporting corporation | What makes it one | Key authority |
|---|---|---|
| A 25%-foreign-owned US corporation | A domestic corporation at least 25% owned — by vote or value — by a single foreign person, after constructive-ownership attribution | §6038A(a), (c)(1) |
| A foreign corporation engaged in a US trade or business | Any foreign corporation carrying on a US trade or business at any time in the year — no ownership threshold | §6038C(a) |
| A foreign-owned US disregarded entity | A US LLC (or other domestic entity) that is disregarded for income tax and wholly owned by one foreign person — deemed a domestic corporation for this purpose only | §301.7701-2(c)(2)(vi); Reg §1.6038A-1(c)(1) |
The first is the §6038A core. A domestic corporation is 25-percent foreign-owned when:
A corporation is 25-percent foreign-owned if at least 25 percent of— (A) the total voting power of all classes of stock of such corporation entitled to vote, or (B) the total value of all classes of stock of such corporation, is owned at any time during the taxable year by 1 foreign person (hereinafter in this section referred to as a "25-percent foreign shareholder").
— IRC §6038A(c)(1)
Three things to hold onto. First, vote or value — crossing 25% on either measure is enough. Second, the 25% must be held by one foreign person (a "25-percent foreign shareholder"); adding together several unrelated foreign owners who are each below 25% does not, by itself, make the corporation a reporting corporation. Third, ownership is tested after attribution — §6038A(c)(5) applies the constructive-ownership rules of §318 (substituting "10 percent" for "50 percent" in §318(a)(2)(C)), so a foreign person who holds the US corporation only indirectly or constructively can still be a 25-percent foreign shareholder, and related foreign persons can be combined.
The second type needs no ownership at all: a foreign corporation engaged in a US trade or business is a reporting corporation under §6038C, whoever owns it (its own section below). The third — the foreign-owned US disregarded entity — is the widely-missed trap, and it gets its own section too.
"Related party" — who the form is about
Form 5472 reports dealings with a related party:
The term "related party" means— (A) any 25-percent foreign shareholder of the reporting corporation, (B) any person who is related (within the meaning of section 267(b) or 707(b)(1)) to the reporting corporation or to a 25-percent foreign shareholder of the reporting corporation, and (C) any other person who is related (within the meaning of section 482) to the reporting corporation.
— IRC §6038A(c)(2)
So a related party is the 25% foreign shareholder itself; anyone related to the reporting corporation or to that shareholder under the §267(b) / §707(b)(1) relationship rules; or anyone within §482 transfer-pricing scope. One carve-out matters in practice: a corporation that files a consolidated federal income tax return with the reporting corporation is not a related party (Reg §1.6038A-1(d)), so dealings inside a consolidated group do not, between themselves, trigger the form.
"Reportable transaction" — the filing gate
Being a reporting corporation is not enough. The form is due only if the company had a reportable transaction with a related party during the year. The regulation enumerates the categories (Reg §1.6038A-2(b)(3)): sales and purchases of inventory, of other tangible property, and of intangibles; rents and royalties; consideration for services; commissions; amounts loaned and borrowed; interest; insurance and reinsurance premiums; and any other amount taken into account in computing the reporting corporation's taxable income. Two features routinely catch preparers off guard:
- There is no de minimis floor for filing. A single small intercompany loan, fee, or royalty is a reportable transaction, and the form is due. (The $10 million and $5 million thresholds you may have heard of relieve only record-keeping, not the filing — see Exceptions from filing.)
- Outstanding balances count, not just current-year cash. Loans are "to be reported as monthly averages or outstanding balances at the beginning and end of the taxable year" (Reg §1.6038A-2(b)(3)(vii)) — so an intercompany loan, note, or open payable/receivable carried over from a prior year is reportable, along with its accrued interest, even if no money moved this year.
In plain terms the trigger is a transaction with a related party, not the ownership percentage. And "transaction" is read broadly: a sale, a payment, a service, a royalty, interest — and an unpaid intercompany balance just sitting on the books from last year. A company can be 25% foreign-owned and owe no Form 5472 because it had no dealings; another can owe one on a single carried-over loan. PILOT asks this as a plain yes/no — did a dealing or an outstanding balance occur — never for the amount.
How the determination runs, in order
Worked in this order, Form 5472 resolves cleanly:
- Is the company a reporting corporation, and which kind? A 25%-foreign-owned US corporation (§6038A), a foreign corporation engaged in a US trade or business (§6038C), or a foreign-owned US disregarded entity (§301.7701-2(c)(2)(vi))? If none, there is no Form 5472.
- Did it have a reportable transaction with a related party during the year? Count current-year dealings and any intercompany balance outstanding in either direction. If there were none, no Form 5472 is due (this is the gate — ownership alone is not enough).
- Does any exception apply? No reportable transactions; the Form 5471 overlap; a foreign sales corporation; a treaty no-permanent-establishment foreign corporation; a §883-exempt foreign corporation; or both parties non-US (several do not apply to a disregarded entity — see below).
If the company clears steps 1 and 2 and no exception applies, it files one Form 5472 for each related party with which it had reportable transactions.
Example 1 — the straightforward filer. FP, a foreign corporation, owns 100% of USC, a US corporation. During the year USC pays FP a royalty for the use of FP's trademarks and interest on an intercompany loan. USC is at least 25% foreign-owned (FP owns 100%), so it is a reporting corporation; the royalty and the interest are reportable transactions with a related party (FP). USC files Form 5472 for FP — one form for that related party.
Example 2 — ownership alone is not enough. Same FP and USC, but this year USC had no dealings with FP or any other related party — no payments, no services, no loans, and no intercompany balance outstanding at any time during the year. USC is still 25% foreign-owned, but with no reportable transaction the filing gate is not met: no Form 5472 is due. (This is the most common false positive — being foreign-owned is mistaken for an obligation to file.)
Example 3 — the outstanding-balance trap. Now change those facts: USC moved no cash with FP this year, but it still carries an intercompany loan payable to FP that it took on in a prior year and has not repaid. There is no current-year cash dealing — yet the outstanding loan balance, and the interest accruing on it, are themselves reportable (loans are reported as monthly averages or outstanding balances — Reg §1.6038A-2(b)(3)(vii)–(viii)). So Form 5472 is still required for FP, in a year with no new transactions at all. A standing intercompany balance carried over from an earlier year can trigger the filing on its own.
The foreign-owned US disregarded entity — the trap that catches the most filers
This is the headline trap, and it is the one most often missed. A US single-member LLC (or other domestic entity) that is disregarded for income tax — it files no income-tax return of its own; its assets and income are simply its owner's — is nonetheless treated as a corporation for Form 5472 purposes when one foreign person owns it. The deeming rule (added by T.D. 9796, effective for tax years beginning on or after January 1, 2017) is in the entity-classification regulations:
An entity that is disregarded as an entity separate from its owner for any purpose under this section is treated as an entity separate from its owner and classified as a corporation for purposes of section 6038A if— (1) The entity is a domestic entity; and (2) One foreign person has direct or indirect sole ownership of the entity.
— Treas. Reg. §301.7701-2(c)(2)(vi)
The §6038A regulations say the same thing from the other side, and add the word domestic:
A domestic business entity that is wholly owned by one foreign person and that is otherwise classified under §301.7701-3(b)(1)(ii) of this chapter as disregarded as an entity separate from its owner is treated as an entity separate from its owner and classified as a domestic corporation for purposes of section 6038A.
— Treas. Reg. §1.6038A-1(c)(1)
The mechanics follow from the deeming. Because the disregarded entity is treated as a corporation only for §6038A, it has no income-tax return of its own — so it must obtain an EIN and file a pro forma Form 1120 (only its name, address, and a few identifying items completed) with Form 5472 attached, by that Form 1120's due date. "Sole ownership" reaches ownership held indirectly through tiers of disregarded entities or grantor trusts, foreign or domestic. And for one of these entities, reportable transactions also include the "other transactions" that fund or unwind it — capital contributions to, and distributions from, the entity, reported on the form's Part V (Reg §1.6038A-2(b)(3)(xi)).
Two reliefs that exist elsewhere do not reach these entities: the record-maintenance reliefs (the $10 million small-corporation and $5 million de minimis safe harbors) and several of the filing exceptions (the Form 5471 overlap, the foreign sales corporation, and the both-parties-non-US exceptions) each expressly exclude a §301.7701-2(c)(2)(vi) entity. A foreign-owned US disregarded entity gets essentially none of the usual off-ramps.
Example 4 — the disregarded-entity trap. A foreign individual owns 100% of a Delaware single-member LLC that has made no check-the-box election, so it is disregarded for US income tax. The LLC holds US real estate and receives capital contributions from, and makes distributions to, its foreign owner. Even though the LLC files no income-tax return of its own, it is treated as a domestic corporation for §6038A: it must obtain an EIN and file a pro forma Form 1120 with Form 5472 attached, reporting the contributions and distributions (Part V) with its foreign owner as the related party. This is the 2017 expansion that swept in countless foreign-owned US real-estate and investment LLCs — and the small-corporation and de minimis record reliefs do not save it.
In plain terms "it's a disregarded LLC, so there's nothing to file" is exactly backwards here. The entity is invisible for income tax yet visible for Form 5472 — it gets an EIN and files a bare-bones Form 1120 only to carry the 5472. Any foreign-owned US LLC with intercompany money movement (or even just money put in and taken out) is a candidate. It is one of the most common Form 5472 misses in practice.
A foreign corporation doing business in the US (§6038C)
The second type of reporting corporation does not turn on ownership at all. A foreign corporation that carries on a US trade or business is brought into the same reporting regime by §6038C:
If a foreign corporation (hereinafter in this section referred to as the "reporting corporation") is engaged in a trade or business within the United States at any time during a taxable year [it shall furnish the information described in subsection (b) and maintain the prescribed records].
— IRC §6038C(a)
There is no 25% test on this path — a wholly foreign-owned foreign corporation operating a US branch is a reporting corporation if it has even one related-party reportable transaction. Section 6038C borrows the §6038A meanings of "related party," "foreign person," and "records" (§6038C(e)) and the §6038A(d) $25,000 penalty (§6038C(c)), and the Form 5472 is filed alongside the foreign corporation's Form 1120-F.
There is, however, a clean escape. A foreign corporation with no US permanent establishment under an applicable income tax treaty is not a reporting corporation at all:
A foreign corporation that has no permanent establishment in the United States under an applicable income tax convention is not a reporting corporation for purposes of section 6038A and this section.
— Treas. Reg. §1.6038A-1(c)(5)(i)
The trade-off is that the corporation must then disclose the treaty position — it timely files Form 8833 under §6114 (and faces that regime's penalties for not doing so). So the §6038C path forks: a US permanent establishment leads to Form 5472; no US permanent establishment under a treaty leads to Form 8833 instead.
Example 5 — §6038C and the treaty fork. FC, a foreign corporation, operates a US branch — a US trade or business — and pays management fees to a foreign affiliate. FC is a reporting corporation under §6038C (no 25% test), and the fees are a reportable transaction with a related party, so FC files Form 5472 alongside its Form 1120-F. Change one fact: if FC has no US permanent establishment under an applicable treaty and timely files Form 8833 to claim that position, FC is not a reporting corporation and files no Form 5472 — its disclosure obligation shifts to the treaty-position return.
Exceptions from filing
Even a reporting corporation with related-party dealings is excused in a handful of situations (Reg §1.6038A-2(e); §1.6038A-1(c)(5)). The first is the gate restated; the rest are genuine exceptions:
| Exception | When it applies | Applies to a foreign-owned US DE? |
|---|---|---|
| No reportable transactions | The corporation had no reportable transactions with any related party during the year | Yes (a DE with genuinely no reportable transactions need not file) |
| Form 5471 overlap | A US person that controls the foreign related corporation files Form 5471 reporting the transactions on Schedule M | No |
| Foreign sales corporation | The related corporation is an FSC that files Form 1120-FSC | No |
| Treaty — no US permanent establishment | A foreign corporation with no US PE under an applicable treaty that timely files Form 8833 | n/a (foreign-corp path) |
| §883-exempt foreign corporation | A foreign corporation all of whose gross income is exempt under §883, complying with §§883 and 887 | n/a (foreign-corp path) |
| Both parties non-US | Both the reporting corporation and the related party are non-US persons, with no US-source/ECI and no allocable US deduction | No |
The first exception is simply the filing gate:
A reporting corporation is not required to file Form 5472 if it has no transactions of the types listed in paragraphs (b)(3) and (4) of this section during the taxable year with any related party.
— Treas. Reg. §1.6038A-2(e)(1)
The exception preparers most often reach for is the Form 5471 overlap: where a US person controls the foreign related corporation and reports the same transactions on Schedule M of a Form 5471, the reporting corporation need not also file Form 5472 for that related party. It is the seam between the inbound and outbound regimes — the transactions get reported once, on the outbound form.
One distinction is worth stating plainly, because conflating the two leads to a missed filing. The exceptions above relieve the filing. They are not the same as the small-corporation ($10 million US gross receipts) and de minimis ($5 million and under 10% of US gross income) safe harbors of Reg §1.6038A-1(h) and (i) — those relieve only the record-maintenance and agent-authorization duties; the corporation "remains subject to the information reporting requirements" and still files Form 5472. And neither safe harbor applies to a foreign-owned US disregarded entity.
In plain terms there are two different kinds of relief and they are easy to mix up. One kind says you don't have to file the form (no transactions, the 5471 already covers it, a treaty applies). The other kind says you still file, you just keep fewer records (the $10M and $5M thresholds). Hitting a dollar threshold never excuses the Form 5472 — and for a foreign-owned US LLC it does not even reduce the recordkeeping.
One Form 5472 for each related party
Form 5472 is filed per related party, not per corporation. A reporting corporation with reportable dealings with three foreign affiliates files three Forms 5472; ten related parties means ten forms. The consolidated-group carve-out narrows the count from the other direction: because a corporation filing a consolidated return with the reporting corporation is not a "related party," intra-group transactions are not reportable between those members. (An affiliated group filing a consolidated return may file a single combined Form 5472, but each member is a separate reporting corporation, separately subject to the $25,000 penalty and jointly and severally liable.)
Example 6 — one form per related party. USC, a US corporation 100%-owned by FP, has reportable dealings during the year with three related foreign companies: it pays a royalty to FP, buys inventory from a foreign sister company, and lends money to a second foreign affiliate. USC files three Forms 5472 — one for each related party — even though all three are part of the same corporate family.
Penalties for getting it wrong
The cost of a missed Form 5472 is what makes the determination worth running carefully:
If a reporting corporation— (A) fails to furnish (within the time prescribed by regulations) any information described in subsection (b), or (B) fails to maintain (or cause another to maintain) records as required by subsection (a), such corporation shall pay a penalty of $25,000 for each taxable year with respect to which such failure occurs.
— IRC §6038A(d)(1)
- $25,000 per failure. A separate Form 5472 is required for each related party, and filing a substantially incomplete Form 5472 is treated as a failure to file — so the $25,000 is, in effect, assessed per form / per related party.
- An uncapped continuation penalty. If the failure continues more than 90 days after the IRS mails notice, an additional $25,000 for each 30-day period (or fraction) applies, with respect to each related party and with no statutory dollar cap (§6038A(d)(2)).
- A records-noncompliance rule with teeth. If the corporation does not comply with an IRS summons for records of a related-party transaction, the IRS may determine the related deduction or cost "in the Secretary's sole discretion" (§6038A(e)(3)).
- An open statute of limitations. Under §6501(c)(8), the assessment period stays open until 3 years after the required information is furnished.
These are statutory dollar amounts — not inflation-indexed — and at $25,000 they are more than double the $10,000 penalty on the §6038 outbound forms (5471, 8858, 8865). A reasonable-cause defense is available (§6038A(d)(3)). PILOT determines whether a Form 5472 obligation exists and for which related parties; it never computes a transaction amount or a penalty.
What recent law changed (and what it did not)
Form 5472's reporting-corporation test is not affected by the headline 2025 international change. The One Big Beautiful Bill Act (OBBBA, Pub. L. 119-21) §70353 restored §958(b)(4) for foreign-corporation tax years beginning after December 31, 2025 — turning off the "downward" attribution from foreign persons that drives controlled-foreign-corporation status and therefore Form 5471 and the PFIC overlap. But the Form 5472 25% test does not run on §958(b). It runs on §6038A(c)(5), which applies the §318 constructive-ownership rules with its own built-in limit on downward attribution: §6038A(c)(5)(B) provides that the §318(a)(3) rules "shall not be applied so as to consider a United States person as owning stock which is owned by a person who is not a United States person." That limit is hard-coded into §6038A itself — it is §6038A's self-contained analog of §958(b)(4), and it neither references nor depends on §958(b). So the §958(b)(4) restoration leaves the 25%-foreign-owned reporting-corporation test unchanged. (Watch the boundary in mixed structures: the same engagement can have a Form 5471 conclusion that shifts for 2026 while the Form 5472 conclusion does not.)
Relationships to other regimes and forms
Form 5472 is the inbound counterpart to a family of outbound forms, and the questions on either side of it decide what applies.
- The outbound mirror. Form 5472 reports a foreign person's dealings with a US-connected company; Form 5471 (foreign corporations), Form 8865 (foreign partnerships), and Form 8858 (foreign disregarded entities and branches) report a US person's interest in a foreign entity. The two regimes meet at the Form 5471 overlap exception (Reg §1.6038A-2(e)(3)): where a US person already reports the related-party transactions on Schedule M of a Form 5471, the reporting corporation does not also file Form 5472 for that related party.
- Classification comes first — and points in the opposite direction. The same check-the-box analysis that classifies a foreign entity for the outbound forms (a per se corporation, or an eligible entity's default under §301.7701-3, electable on Form 8832 — described in the Form 8858 and Form 8865 guides) is what makes a US single-member LLC "disregarded." When that disregarded US entity is foreign-owned, the classification that erases it for income tax is exactly what pulls it onto Form 5472. Run the classification before concluding anything.
- Only C corporations and foreign-owned DEs file 5472. A US partnership is not a §6038A reporting corporation, and a 25%-foreign-owned S corporation generally cannot exist (a nonresident-alien shareholder terminates the S election). A foreign-owned US partnership may have its own obligations — Form 8865 up the chain, or Forms 8804/8805 and 1042 — but not Form 5472.
- Foreign-asset disclosure is separate. A 25% foreign shareholder's interest in the US corporation, and the corporation's own foreign accounts, can raise FBAR and Form 8938 questions for the people involved; and foreign stock held below a foreign-owned US entity can pull its owner into a PFIC / Form 8621 analysis. Form 5472 sits alongside these, not in place of them.
In plain terms think of Form 5472 as the US system asking the inbound version of the question the 5471 and 8865 ask going outbound: who is on the other side of these cross-border dealings, and what passed between you? If a US person already answered it on a Form 5471, the 5472 may not also be needed. And the very thing that makes a foreign-owned US LLC invisible for income tax is what makes it a Form 5472 filer. PILOT determines, for each company in a structure, which of these forms is required and why.
What Form 5472 is not
Form 5472 reports — it does not compute your client's tax. The transfer-pricing analysis behind the related-party amounts, any §59A base-erosion tax, and the income-tax treatment of the transactions themselves are separate, downstream work that builds on the facts the form captures. The first question — and the one this guide answers — is simply whether a Form 5472 obligation exists: for which company, for which related parties, and whether any exception switches it off.
