Two forms, very different filers — which one is yours?
Form 5471 and Form 5472 sound like siblings. They are not. One is filed by US persons looking outward at a foreign corporation they own. The other is filed by US entities owned by a foreign person looking inward. Mix them up and you either miss a $10,000 penalty under Form 5471 or a $25,000 penalty under Form 5472 — sometimes both.
The simplest way to keep them straight: Form 5471 follows the US person across borders. Form 5472 follows foreign money into the US. Below is the decision logic, the filing thresholds, and the worked examples that put real names on each path.
The decision tree — which form (if any) applies to you
Two questions answer 95% of cases. Are you a US person or a foreign person? And does your entity sit inside or outside the United States?
Form 5471 — for US persons with foreign corporations
Form 5471 is filed under IRC §§6038 and 6046 by a US person who owns or controls a foreign corporation. It is attached to your US tax return — Form 1040 if you are an individual, Form 1120 if you are a US corporation. The deadline is the same as your return: April 15 for individuals, March 15 for S-corps and partnerships, with extensions available.
The IRS divides filers into five numbered categories — and Categories 1 and 5 are now subdivided into 1a/1b/1c and 5a/5b/5c, which is why some references count nine. The category determines which schedules you file, not whether you file. A single Form 5471 covers all applicable categories for one foreign corporation.
Continuation: Additional $10,000 for every 30 days after a 90-day IRS notice
Maximum: $60,000 per form per year (initial $10,000 plus continuation cap of $50,000)
Statute of limitations: Tax return stays open until 3 years after Form 5471 is filed; if never filed, indefinitely
Form 5472 — for foreign-owned US entities
Form 5472 is filed under IRC §§6038A and 6038C. It applies in two distinct scenarios that often get conflated. First, any US C-corporation with 25% or more foreign ownership and at least one reportable transaction with a related party must file. Second, since 2017, any US single-member LLC with a foreign owner must file — even if the LLC has no income, no employees, and no operations beyond holding a Stripe account.
For the C-corp, Form 5472 attaches to the regular Form 1120 and gets e-filed with everything else. For the foreign-owned LLC, the package is different and trips up almost every founder filing without help: you attach Form 5472 to a pro forma Form 1120 (mostly blank, just identification fields), write "Foreign-owned U.S. DE" across the top of both, and mail or fax it to a special IRS address in Ogden, Utah. E-filing is not available for the LLC version.
Continuation: Additional $25,000 for every 30 days after a 90-day IRS notice
Maximum: No statutory cap — penalties continue accruing
E-filing: Available for C-corps; not available for foreign-owned LLCs (mail or fax only)
Side-by-side comparison
The two forms answer opposite questions. Once you see them next to each other, the rest of the rules follow.
Entity reported: Foreign corporation
Threshold: 10% (Cat 2, 3, 5) or >50% (Cat 4)
Filed with: Form 1040 or Form 1120
Penalty: $10,000 / $60,000 max per year
IRC: §§6038, 6046
E-file: Yes, with the underlying return
Entity reported: The US entity itself
Threshold: 25% foreign-owned C-corp, or any % foreign-owned single-member LLC
Filed with: Form 1120 (or pro forma 1120 for LLC)
Penalty: $25,000 per form, no cap
IRC: §§6038A, 6038C
E-file: C-corps yes, LLCs no
Worked example — Berik in Almaty with a Wyoming LLC
Berik is a Kazakhstan tax resident running an Amazon FBA store through a Wyoming single-member LLC he formed in 2024. The LLC sells phone accessories to US customers and remits roughly $40,000 of profit per year to Berik's Kazakhstan account. Berik is the sole owner and has no US presence, no US employees, and no US visa.
- Form 5471? No. Berik is not a US person, so the outbound regime does not apply to him.
- Form 5472? Yes. His Wyoming LLC is a foreign-owned single-member LLC. Each year of operation triggers a Form 5472 filing covering the formation contributions, profit distributions, and any other related-party transactions.
- Filing package: Pro forma Form 1120 + Form 5472, mailed or faxed to the Ogden address. Cannot e-file.
- Penalty if missed: $25,000 per year. Three years missed = $75,000 minimum exposure, before continuation penalties.
Berik does not owe US income tax on the LLC profits because the LLC is a disregarded entity and he has no US trade or business in the way the IRS defines it for FBA in many fact patterns — but the information return is non-negotiable regardless of tax owed.
Worked example — Chen in Singapore with a Delaware C-corp
Chen lives in Singapore and owns 100% of a Delaware C-corporation that licenses SaaS software to US customers. The corporation generated $800,000 in revenue last year and paid Chen a $150,000 management fee through an intercompany agreement.
- Form 5471? No. Chen is not a US person.
- Form 5472? Yes. The Delaware C-corp is more than 25% foreign-owned and has reportable transactions with Chen (the management fee).
- Filing package: Form 1120 (regular corporate return, since this is a real C-corp paying real tax) with Form 5472 attached. E-file is allowed here.
- Additional consideration: The intercompany management fee triggers transfer pricing scrutiny under IRC §482. Documentation should support that the fee is arm's length.
Worked example — US person with a foreign corporation
Compare both of the above to a US citizen who owns 100% of a UK Ltd that consults to UK clients. She is the opposite case — outbound, not inbound.
- Form 5471? Yes. She is a Category 4 filer (US person controlling a foreign corporation) and a Category 5 filer (10%+ shareholder of a CFC, since she alone exceeds 50%).
- Form 5472? No. The UK Ltd is not a US entity and the IRS only requires Form 5472 for US filers.
- Additional considerations: NCTI (formerly GILTI) and Subpart F income inclusions on her Form 1040, Form 8992 for NCTI calculation, and potentially FBAR (FinCEN 114) and Form 8938 if she has signature authority over the UK Ltd's bank accounts.
The "I have both" scenario
The dual-filing trap catches US citizens living abroad who run their lives through both a US LLC (for invoicing US clients) and a foreign corporation (for local-country tax efficiency). The IRS sees these as completely separate compliance obligations.
If you are a US person and you own a foreign corp at 10%+, you file Form 5471 with your Form 1040. If that same Form 1040 also reports income from a single-member LLC you own, the LLC is disregarded and the activity flows onto your Schedule C — no Form 5472 because the owner is a US person, not foreign. But if a foreign person co-owns the LLC at 25%+, or if the LLC is owned by your foreign corporation, Form 5472 enters the picture for the LLC and you have both forms in play. Each carries its own penalty pool.
If you are catching up on missed filings
Both forms have penalty relief paths, but the routes diverge.
For Form 5471, the Delinquent International Information Return Submission Procedures (DIIRSP) and Streamlined Filing Compliance Procedures are the main routes for non-willful failures. The IRS's 2020 changes to DIIRSP made it less generous than before — it is no longer an automatic penalty waiver — but reasonable cause statements filed before the IRS contacts you still produce better outcomes than waiting for a CP15 notice.
For Form 5472, reasonable cause is the primary defense. Filing the missed years before IRS contact, with a written reasonable cause statement attached, is the standard catch-up procedure. The IRS has historically been less forgiving on Form 5472 than on Form 5471 because the underlying disregarded-entity rule was published with extensive industry warnings starting in 2017.
In both cases, do not file under the wrong form thinking it will count. Filing a Form 5472 when you needed a Form 5471 (or vice versa) is treated as a failure to file the correct form — the penalty applies anyway.
Common mistakes
- Confusing direction. Filing Form 5471 because your LLC has a foreign owner, or filing Form 5472 because you (a US person) own a foreign corp. Direction of the relationship determines the form.
- Assuming zero activity means no filing. A foreign-owned LLC that received only an initial capital contribution still has a reportable transaction (the contribution itself).
- Filing one Form 5472 for multiple foreign related parties. Each related party needs a separate Form 5472. A C-corp with three foreign shareholders meeting the 25% threshold files three forms.
- Missing Form 5471 across multiple foreign corporations. The $10,000 penalty stacks per corporation per year. Owning interests in three foreign corps and missing one year = $30,000 in initial penalties, before continuation.
- E-filing the foreign-owned LLC pro forma 1120. The IRS does not accept e-filing for this package. It must be mailed or faxed to the Ogden address.
Frequently asked questions
Living abroad does not change your status as a US person. If you own 10% or more of a foreign corporation, you file Form 5471. If a foreign relative or business partner owns 25% or more of your US LLC or C-corp, the US entity files Form 5472. Both can apply to the same person in the same tax year.
Yes. Form 5471 starts at $10,000 per corporation per year and caps at $60,000 per form per year after continuation. Form 5472 starts at $25,000 per related party per year and has no statutory maximum on continuation penalties.
Form 5471 e-files with your tax return when your software supports it. Form 5472 e-files with Form 1120 for a regular C-corp. The pro forma Form 1120 + Form 5472 package for a foreign-owned single-member LLC cannot be e-filed — it must be mailed or faxed to the IRS Ogden address.
A dual citizen of the US and any other country is a US person for tax purposes. The non-US citizenship is irrelevant to the analysis. Apply the same outbound (Form 5471) and inbound (Form 5472) tests as any other US person.
No. Multi-member LLCs default to partnership taxation and file Form 1065 with Schedules K-1. Form 5472 in the LLC pro forma 1120 package only applies to single-member LLCs treated as disregarded entities.
Yes, in almost every case. The formation of the LLC and any capital contribution from the foreign owner are themselves reportable transactions. The IRS rules treat formation, dissolution, and contributions as Part V transactions for disregarded entities.
No. Filing Form 5472 when Form 5471 was required (or vice versa) is treated as a failure to file the correct form. The penalty applies as if nothing had been filed. The two forms are not interchangeable, even though both deal with cross-border ownership.
