The short answer: Form 5471 is filed by US persons who own or control a foreign corporation (ownership flowing outward, from the US to abroad). Form 5472 is filed by US companies that are at least 25% foreign-owned, and by foreign corporations doing business in the US (ownership flowing inward). Missing either form costs $10,000 (Form 5471) or $25,000 (Form 5472) per form per year to start, and keeps the IRS’s time to assess that year’s return open.
Two IRS forms that look similar and work nothing alike. Pick the wrong one, or miss one you did not know you owed, and the penalties start at $10,000 to $25,000 per form, per year.
If you own a US company with foreign investors, or you are a US person with a stake in a foreign corporation, you will meet these two forms sooner or later. This guide explains the real difference, shows who files which, and gives you a five-question method to settle your own requirement in a few minutes. For the full mechanics of one of them, see our complete Form 5472 filing guide.
Key takeaways
- Direction decides: Form 5471 tracks outbound ownership (a US person owning a foreign corporation); Form 5472 tracks inbound ownership (a foreign person owning a US entity).
- Different penalties: Form 5471 starts at $10,000 and is capped at $60,000 per corporation per year; Form 5472 starts at $25,000 with no cap.
- The most-missed filing: a foreign-owned single-member LLC must file Form 5472 with a pro forma Form 1120, even with no income, because funding the LLC is a reportable transaction.
- Dormant still counts: Form 5471 is required even if the foreign corporation did nothing all year.
- Open years: a missing form keeps the assessment period for that year’s return open.
- Often both: many cross-border structures need both forms in the same year.
The Core Distinction: Which Way Does Ownership Flow?
Before you look at a single line on either form, answer one question: in your structure, who owns whom across the US border? That direction decides everything.
Form 5471 exists so the IRS can see US money invested in foreign companies. If you are a US citizen, green card holder or US company with a meaningful stake in a corporation formed abroad, the IRS wants a full picture of that company: its ownership, earnings and financial statements. That is outbound reporting, and it can create current US tax through Subpart F income and net CFC tested income (called GILTI before the 2025 tax law, for tax years beginning after December 31, 2025).
Form 5472 exists for the opposite reason: so the IRS can see foreign money invested in US companies. If a US corporation or LLC is at least 25% foreign-owned, the IRS wants a record of the transactions between that entity and its foreign owners and related parties. That is inbound reporting, and it is purely informational; Form 5472 does not calculate any tax. If you are setting up a US entity, our US company registration service can get it structured correctly from the start.

Who Must File Each Form
Form 5471 turns on your ownership status; Form 5472 turns on foreign ownership of a US entity and its related-party transactions.
Who Must File Form 5471
Form 5471 applies to US persons who fall into one or more of five filer categories tied to a foreign corporation:
| Category | Who it covers |
|---|---|
| Category 1 | US shareholders of certain specified foreign corporations (Section 965 related) |
| Category 2 | US citizens or residents who are officers or directors of a foreign corporation in which a US person acquires 10% or more |
| Category 3 | US persons who acquire 10% or more of a foreign corporation's stock, or dispose of enough to fall below 10%, or become US persons while owning 10% |
| Category 4 | US persons who control a foreign corporation (more than 50% of vote or value) during the year |
| Category 5 | US shareholders (10% or more) of a controlled foreign corporation (CFC), meaning one more than 50% owned by US shareholders together |
Ownership includes stock held directly, indirectly and by attribution from family members and related entities. Your category decides which schedules you complete, and Category 5 is both the most common and the most schedule-heavy. The requirement depends on your ownership, not the company’s activity, so a dormant foreign corporation still needs Form 5471. It is also where current US tax can arise, because its data feeds the Subpart F and net CFC tested income calculations on your return.
Who Must File Form 5472: The Trap Most Owners Miss
- No e-filing: a foreign-owned disregarded entity cannot e-file. It must mail or fax the pro forma Form 1120 and Form 5472 to the IRS address or fax line given in the instructions, by April 15 for a calendar year or October 15 with a Form 7004 extension.
- Ignorance is not a defense: many Amazon seller LLCs, real estate holding LLCs and e-commerce companies owned by non-residents learn about this requirement only from a penalty notice. See our LLC tax guide for Indian entrepreneurs for the full set of filings.
The 5-Question Decision Method
Work through these in order.
- Are you a US person for tax purposes? US persons include US citizens, residents (green card holders and others who meet the residency tests), and domestic corporations, partnerships, trusts and estates. Yes: go to question 2. No: go to question 3.
- Do you own or control a foreign corporation? Ownership generally means 10% or more, directly or through family or entity attribution; control means more than 50% of vote or value. Yes: you need Form 5471; continue to question 3 to check Form 5472. No: continue to question 3.
- Do you have a US entity? A corporation, LLC or partnership. Yes: go to question 4. No: you are done.
- Is the US entity 25% or more foreign-owned at any time during the year? Count direct and indirect ownership. Yes: go to question 5. No: Form 5472 is not required.
- Was there a reportable transaction with a related party? Sales, purchases, rents, royalties, interest, fees, loans or capital contributions, with no minimum. Yes: you need Form 5472. No, and the entity is a regular corporation: Form 5472 is not required. If the entity is a foreign-owned single-member LLC, check carefully: funding it or paying its costs counts as a transaction, so a filing is almost always due.
When You Must File Both Forms in the Same Year
Many international structures push ownership in both directions at once. When that happens, both forms are due each year, and missing either one brings its own penalty and keeps the return open.
| Your structure | Form 5471? | Form 5472? | Why |
|---|---|---|---|
| US person owns a foreign corporation; no foreign-owned US entities | Yes | No | Only outbound ownership |
| US entity has foreign owners; no US person owns a foreign corporation | No | Yes | Only inbound ownership |
| US person owns a foreign corporation and a US entity is 25% or more foreign-owned | Yes | Yes | Ownership flows both ways |
| Foreign parent owns a US subsidiary that owns a separate foreign corporation | Yes (by the US subsidiary) | Yes (by the US subsidiary) | The US entity is foreign-owned and owns a foreign corporation |
| Purely domestic structure | No | No | No cross-border ownership |
When you file both, keep them consistent. Where the same entities, ownership percentages or transactions appear on both forms, the names, percentages and currency conversions should match. Inconsistencies are an easy audit flag.
Cross-border filing is where do-it-yourself goes wrong fastest. If ownership runs in both directions, talk to a CPA who handles both before the deadline, not after a notice.
Penalties Compared, and the Open Statute of Limitations
Form 5471 starts at $10,000 per foreign corporation per year, adds $10,000 for each 30 days the failure continues after a 90-day IRS notice, and caps at $60,000 per corporation per year; the IRS can also reduce your foreign tax credits. Form 5472 starts at $25,000 per form per year, adds $25,000 for each 30 days after the notice period, and has no cap.
Worked example: a foreign-owned single-member LLC never filed Form 5472. The IRS assesses $25,000 and sends a notice. If the form is still not filed 90 days later, another $25,000 is added for each 30 days. Four months after the 90-day window closes, the total is $125,000 for a single year, for a company that may owe no US income tax at all.
The penalty is often not the worst part. When either form is missing, the time limit for the IRS to assess tax on that year’s return does not start running. The normal three-year window never opens, so the IRS can examine the whole return, not just the international piece. If the failure was due to reasonable cause and not willful neglect, only the items related to the missing form stay open. For an owner who skipped a form for several years, that open-ended exposure can matter more than the penalties.
Do not rely on the Farhy case as a shield. In 2023 the Tax Court held that the IRS could not assess Form 5471 penalties administratively, but the D.C. Circuit reversed that decision in 2024. Treat both filing requirements as fully enforceable. For Form 5472 deadlines in detail, see our guide to Form 5472 deadlines and penalties.
What If You Already Missed a Filing?
Missing a prior-year Form 5471 or Form 5472 is common and fixable, but the route matters. Do not simply start filing going forward and hope the gap goes unnoticed; a quiet forward-only fix can look worse than the original miss.
- File before the IRS contacts you. Correcting voluntarily, before a notice or examination, gives the best chance of relief.
- Write a reasonable cause statement. A documented, honest explanation of why the form was missed is the main defense against the penalty.
- Use the Delinquent International Information Return Submission Procedures if you qualify. They are the usual route for late international information returns, but penalties can still be assessed, so the reasonable cause statement carries the weight.
Because the facts decide which relief path fits, a missed filing is the moment to bring in a professional rather than improvise.

Frequently Asked Questions
1. What is the main difference between Form 5471 and Form 5472?
Form 5471 is filed by US persons who own or control a foreign corporation, so it tracks outbound ownership. Form 5472 is filed by US entities that are 25% or more foreign-owned, and by foreign corporations doing business in the US, so it tracks inbound ownership and related-party transactions. The difference is the direction ownership flows across the border.
2. Can I be required to file both Form 5471 and Form 5472 in the same year?
Yes. If a US person owns a foreign corporation and a US entity in the same structure is 25% or more foreign-owned, both forms are required. A common example is a foreign parent that owns a US subsidiary, which in turn owns another foreign company: the US subsidiary files Form 5472 for its foreign parent and Form 5471 for the company it owns.
3. What are the penalties for not filing Form 5471 or Form 5472?
Form 5471 penalties start at $10,000 per foreign corporation per year, plus $10,000 for each 30 days the failure continues after an IRS notice, up to $60,000 in total. Form 5472 penalties start at $25,000 per form, plus $25,000 for each 30 days after notice, with no cap. A missing form also keeps the assessment period for that year’s return open.
4. Do I need to file Form 5471 if my foreign corporation had no income or activity?
Yes. Form 5471 is required even when the foreign corporation is dormant, as long as you fall into one of the five filer categories. The requirement depends on your ownership, not the company’s activity.
5. Do I need to file Form 5472 if my US entity had no transactions with foreign related parties?
Generally no, unless the US entity is a foreign-owned disregarded entity, such as a single-member LLC owned by a foreign person. Those must file Form 5472 with a pro forma Form 1120 whenever there is any reportable transaction, and putting money into the LLC or paying its formation costs counts. In practice almost every foreign-owned single-member LLC files in its first year.
6. Can a foreign-owned US LLC file Form 5472 electronically?
No. A foreign-owned single-member LLC treated as a disregarded entity must mail or fax its pro forma Form 1120 and Form 5472 to the IRS by the due date, April 15 for a calendar year or October 15 with an extension. US corporations can e-file Form 5472 with their Form 1120.
7. What if I already missed a Form 5471 or Form 5472?
File the missing forms as soon as possible, before the IRS contacts you, with a reasonable cause statement. If you qualify, the Delinquent International Information Return Submission Procedures are the usual route. Penalties can still be assessed, so the strength of the reasonable cause explanation matters.
