Form 5472 vs Form 5471: Which One You Must File
Two IRS forms that look similar and behave nothing alike. Pick the wrong one, or miss a filing, and penalties start at $10,000 to $25,000 per form, per year with no statute of limitations protecting the rest of your return.
If you own a US company with foreign investors, or you are a US person with a stake in a foreign corporation, sooner or later you run into two IRS forms that look similar and behave nothing alike: Form 5472 and Form 5471. Pick the wrong one, or miss a filing you did not know you owed, and the penalties start at $10,000 to $25,000 per form, per year, with no statute of limitations protecting the rest of your tax return. This guide breaks down the real difference, shows you exactly who files which, and gives you a five-question method to settle your own filing requirement in a few minutes. For the full mechanics of one of these forms, you can also read our complete Form 5472 filing guide.
The short answer: Form 5471 is filed by US persons who own or control a foreign corporation (ownership flowing outward, US to foreign). Form 5472 is filed by US entities that are at least 25% foreign-owned, or by foreign corporations doing business in the US (ownership flowing inward, foreign to US). The entire distinction comes down to the direction ownership travels across the border.
Key Takeaways
- Form 5471 tracks outbound ownership: a US person owning a foreign corporation. Form 5472 tracks inbound ownership: a foreign person owning a US entity.
- Form 5471's penalty starts at $10,000 and is capped at $60,000 per corporation, per year. Form 5472's penalty starts at $25,000 and has no cap, so exposure can climb into six figures.
- A foreign-owned single-member LLC (a disregarded entity) must file Form 5472 with a pro forma Form 1120 even with zero income, purely because it was funded. This is the single most-missed filing we see.
- Form 5471 must be filed even if the foreign corporation is dormant. The trigger is your ownership status, not the company's activity.
- Not filing either form keeps the statute of limitations on your entire tax return open indefinitely, so the IRS can audit that year forever.
- Many cross-border structures require both forms in the same year. Missing one does not excuse the other.
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, and you hold a meaningful stake in a corporation registered abroad, the IRS wants a full picture of that foreign company, its ownership, its earnings, and its financial statements. That is outbound reporting, and it can actually create current US tax through Subpart F income and GILTI (renamed Net CFC Tested Income for tax years beginning after December 31, 2025 under the One Big Beautiful Bill Act).
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 flowing between that US entity and its foreign owners or related parties. That is inbound reporting, and it is purely informational. Form 5472 does not calculate tax by itself. If you want to get your US entity structured correctly from the start, our team can help through US company registration and compliance setup.
Hold that one idea, direction of ownership, and the rest of this comparison falls into place.
The one requirement you cannot skip is a registered agent. This is a person or company with a physical Wyoming address who receives legal and government documents on your LLC’s behalf. As a non-resident, you will use a professional registered agent service, which also keeps your home address off the public record.

⬤ Who Files What
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. Here is exactly who each one captures.
Who Must File Form 5471
Applies to US persons who sit in one of five filer categories tied to a foreign corporation. In plain terms, you are likely a filer if any of these describe you:
- You own 10% or more of a foreign corporation's stock, directly, indirectly, or by constructive (family) attribution.
- You are a US officer or director of a foreign corporation in which a US person acquires a 10% stake.
- You acquired or disposed of a 10%+ interest during the year.
- You control the foreign corporation, meaning more than 50% of vote or value for 30 consecutive days or more, making it a controlled foreign corporation (CFC).
The category you fall into determines which schedules you complete, and Category 5 (US shareholders of a CFC) is both the most common and the most schedule-heavy. Critically, the filing requirement is based on your ownership status, not the company’s activity: a dormant foreign corporation with zero income still requires Form 5471. Form 5471 is also where current US tax can arise, because the data feeds Subpart F and GILTI/NCTI calculations.
Who Must File Form 5472 (The Trap Most Miss)
Applies when a US entity is at least 25% foreign-owned and has a reportable transaction with a related party during the year. A reportable transaction is deliberately broad: sales, purchases, rents, royalties, interest, service fees, commissions, loans, and capital contributions all count, and there is no minimum dollar threshold. A single $1 transaction triggers the filing.
Here is the trap. For a normal US corporation, if there were no reportable transactions, there is no Form 5472. But a foreign-owned single-member LLC, treated as a disregarded entity, is a different animal. Since tax years beginning on or after January 1, 2017 (under Treasury Regulation 1.6038A-1(c)), these entities must file Form 5472 attached to a pro forma Form 1120 every year they have any reportable transaction, and funding the LLC’s own bank account counts as a reportable capital contribution. In practice that means almost every foreign-owned US LLC owes a Form 5472 in its first year, even with zero revenue, zero expenses, and zero US tax due.
Two more details that trip people up:
- The foreign-owned disregarded entity cannot e-file. It must mail or fax the pro forma 1120 and Form 5472 to the IRS's dedicated Ogden address or fax line.
- Thousands of Amazon-seller LLCs, US real-estate holding LLCs, and non-resident e-commerce entities discovered this requirement only after a penalty notice arrived. Not knowing is not a defense.
⬤ Decide In Minutes
The 5-Question Decision Method
Are you a US person or entity for tax purposes?
Do you own or control a foreign corporation?
Do you have a US entity?
Is your US entity 25% or more foreign-owned?
Did any reportable transaction occur?
When You Must File Both Forms in the Same Year
Plenty of international structures push ownership in both directions at once: a US person owning a foreign corporation, while also holding a US entity that has foreign owners. When that happens, you file both forms annually. Missing either one triggers its own separate penalty and keeps your return’s statute of limitations open.
| Your Structure | Form 5471? | Form 5472? | Why |
|---|---|---|---|
| US person owns a foreign corporation only; no foreign-owned US entities | Yes | No | Only outbound ownership exists. |
| US entity has foreign owners only; no US person owns a foreign corporation | No | Yes | Only inbound ownership exists. |
| US person owns a foreign corporation AND a US entity is at least 25% foreign-owned | Yes | Yes | Ownership flows in both directions. |
| Foreign parent owns a US subsidiary that itself owns a separate foreign corporation | Yes | Yes | The US entity is foreign-owned and also owns a foreign corporation. |
| Purely domestic structure with no cross-border ownership | No | No | No international reporting requirement. |
When you do file both, keep them consistent. If your Form 5471 shows the foreign corporation owns 40% of your US entity, your Form 5472 must show the same 40%. Currency conversions, entity names, and ownership percentages should match line for line across the two forms. Inconsistencies are an easy audit flag.
Cross-border filing is where do-it-yourself goes wrong fast. If your structure has ownership running in both directions, talk to a CPA who handles both before the deadline, not after a notice.
⬤ The Real Danger
Penalties Compared, and the Open Statute of Limitations
The dollar penalties differ meaningfully. Form 5471 starts at $10,000 per foreign corporation per year, adds $10,000 for each 30-day period after the IRS 90-day notice, and caps at $60,000 per corporation per year. Form 5472 starts at $25,000 per form per year, adds $25,000 per 30-day period after notice, and has no maximum cap at all. A single missed Form 5472 can run from $25,000 to $100,000 within months of an IRS notice.
But the penalty is often not the worst part. When either form is missing, the statute of limitations on your entire tax return for that year does not start running. The normal three-year audit window never opens, so the IRS can examine that return indefinitely, every income item on it, not just the international piece. For an owner who quietly skipped a form for five years, that open-ended exposure is usually a bigger problem than the stacked penalties.
One more current reality: taxpayers should not lean on the Farhy decision as a shield. The D.C. Circuit reversed it in 2024, and appellate courts have since backed the IRS’s authority to assess these penalties. Treat the filing requirement as fully enforceable.
What If You Already Missed a Filing?
Missing a prior-year Form 5471 or Form 5472 is common, and it is fixable, but the path matters. Do not simply start filing going forward and hope the gap is overlooked; a quiet forward-only fix can look worse than the original miss.
- File before the IRS contacts you. Voluntary correction before a notice dramatically improves your odds of penalty relief.
- Reasonable cause statement. Attaching a documented, honest explanation of why the form was missed is the primary defense against the penalty.
- Delinquent International Information Return Submission Procedures (DIIRSP) is the route many owners use to catch up on missed international information returns with a reasonable-cause narrative.

Frequently Asked Questions
Form 5471 is filed by US persons who own or control a foreign corporation, tracking outbound US ownership. Form 5472 is filed by US entities that are 25% or more foreign-owned, tracking inbound foreign ownership and related-party transactions. The distinction is the direction ownership flows across the US border.
Yes. Non-residents without an SSN or ITIN obtain an EIN by submitting Form SS-4 to the IRS by fax or mail, rather than using the online tool.
Form 5471 penalties start at $10,000 per foreign corporation per year, add $10,000 for each 30-day period after IRS notice, and cap at $60,000 per corporation per year. Form 5472 penalties start at $25,000 per form, add $25,000 per 30-day period, and have no cap. Both forms also keep your entire tax return’s statute of limitations open indefinitely if not filed.
Yes. Form 5471 must be filed even when the foreign corporation is dormant or had zero income, as long as you meet one of the five filer categories. The requirement is based on your ownership status, not the company’s activity.
Generally no, unless your US entity is a foreign-owned disregarded entity (a single-member LLC owned by a foreign person). Those entities must file Form 5472 with a pro forma Form 1120 even with zero activity, because simply funding the LLC counts as a reportable transaction.
No. A foreign-owned single-member LLC treated as a disregarded entity cannot e-file. It must mail or fax the pro forma Form 1120 and Form 5472 to the IRS’s dedicated address or fax line by the return deadline. Standard US corporations, by contrast, can e-file Form 5472 with their Form 1120.
