Form 5472 is a mandatory IRS information return for every foreign-owned US LLC. Filing it correctly — and on time — is the difference between a $0 penalty and a $25,000+ fine. This is the only guide you need.
Form 5472 is a mandatory IRS information return for foreign-owned US LLCs. If you own 100% of a single-member US LLC as a non-resident alien, you must file Form 5472 with a pro forma Form 1120 every year — even if your LLC had no revenue. Failure to file triggers a minimum penalty of $25,000 per form (increased from $10,000 for returns required after December 31, 2025). The IRS treats foreign-owned disregarded entities as domestic corporations for reporting purposes. Form 5472 does not create a US tax liability — it only reports transactions between you and your LLC. Understanding this distinction is the first step to staying compliant and avoiding IRS penalties.
For Form 5472 returns required for taxable years beginning on or after January 1, 2026, the minimum penalty has jumped from $10,000 to $25,000. If you receive an IRS notice and still fail to comply, an additional $25,000 penalty applies. There is no cap on penalties for continued non-compliance. If you haven't been filing Form 5472, correct this immediately — the IRS rarely sends a warning before assessing penalties.
Form 5472 applies to any US corporation or LLC with a 25%+ foreign owner. The rules differ based on entity type.
Does this entity type require Form 5472? (Foreign owner = 25%+ ownership by non-US person)
| Entity Type | Foreign Owner? | File Form 5472? | Notes |
|---|---|---|---|
| Single-Member LLC (owned by non-resident alien) |
✓ | ✓ YES | Most common. File even with $0 revenue. |
| Single-Member LLC (owned by US person) |
✗ | ✗ NO | Disregarded entity, no separate filing required. |
| Multi-Member LLC (at least one 25%+ foreign owner) |
✓ | ✓ YES | Each foreign owner owning 25%+ requires a separate Form 5472. |
| Multi-Member LLC (all owners US persons) |
✗ | ✗ NO | File Form 1065 (partnership return) instead. |
| Delaware/Wyoming C-Corp (foreign shareholders) |
✓ | ✓ YES | Required annually regardless of profitability. |
| S-Corp (foreign 25%+ owner) |
✓ | ✓ YES | Both Form 1120-S and Form 5472 required. |
A single-member LLC owned by a non-resident alien is treated as a disregarded entity for US tax purposes. But it's NOT disregarded for IRS reporting. You must still file Form 5472 with a pro forma Form 1120 every year — even though your personal income tax return (1040-NR) already captures the LLC's income.
Missing a Form 5472 deadline is expensive. Here's exactly what you face.
| Deadline Type | Date | Notes |
|---|---|---|
| Standard Filing | April 15 | Attach Form 5472 to pro forma Form 1120. File by mail or fax. |
| Extended Deadline | October 15 | File Form 7004 (Application for Automatic Extension) by April 15 to get 6 more months. Form 7004 does not extend time to pay any tax due. |
| First Year Relief | Varies | New entities filing their first Form 5472 may qualify for a one-time 90-day automatic extension upon written request to the IRS. |
Tier 1 (Automatic): $25,000 per form for returns required for taxable years beginning after December 31, 2025. This penalty applies automatically — the IRS does not need to contact you first.
Tier 2 (Post-Notice): Additional $25,000 if you fail to file after receiving an IRS notice. The IRS typically sends at least one notice before assessing this penalty, giving you a window to correct the failure.
Continued Non-Compliance: Penalties can compound significantly for multi-year non-filers. There is no maximum penalty ceiling. The IRS can also pursue criminal penalties for willful evasion.
If you have not received an IRS notice, the $25,000 penalty does not apply to late filers who voluntarily come into compliance. File immediately and include a reasonable cause statement explaining why you filed late. If you have received an IRS notice, consult a tax attorney immediately — reasonable cause arguments are more complex at that stage.
Form 5472 Part V requires you to disclose all transactions between the foreign owner and the US LLC. Here is every category that must be reported.
Money or property you transfer into the LLC as equity. Even a $500 wire from your foreign bank to fund initial operations counts.
Money you loan to the LLC — including intercompany loans, lines of credit you extend, or personal funds wired to the business account.
Money the LLC loans back to you or to any related foreign party. Repayment of loans, interest payments, and principal returns all count.
Any payment to you personally for services rendered — consulting fees, contractor fees, director fees, management fees paid to a foreign entity you own.
The LLC reimbursing you for business expenses you paid personally — travel, software subscriptions, office supplies, legal fees paid on behalf of the LLC.
Payments for intellectual property, software licenses, trademarks, or franchise fees paid by the LLC to a related foreign party.
Profit distributions from the LLC to the foreign owner. Even if characterized as a distribution (not salary), it must be reported on Form 5472.
Rent paid by the LLC to a foreign landlord or property owner related to the foreign owner. Also includes lease payments on equipment.
If there were truly no reportable transactions during the year, check the box in Form 5472 Part V indicating no reportable transactions occurred. You still file the form — it takes 10 minutes. The alternative (not filing) costs $25,000. If your LLC received any money from you or sent any money to you, that is a reportable transaction.
Seven steps from EIN to filing. No e-file, no accountant required for straightforward cases.
Apply for an Employer Identification Number (EIN) — required for all US LLCs regardless of whether you have employees. No SSN or ITIN is required. Apply online at irs.gov/ein, by phone at +1-267-941-1099 (Mon–Fri, 6am–11pm ET, toll-free), or by completing IRS Form SS-4 and faxing it to the IRS. EIN is issued immediately by phone, within 4 business days by mail/fax. Keep the EIN confirmation letter — your bank and the IRS will ask for it.
⏱ Same day (phone/online)Before completing Form 5472, collect: your full legal name (as it appears on your passport), home address in your country of citizenship, country of citizenship, date of birth, and passport number. For the LLC: formation date, state of formation, EIN, principal business activity, and principal place of business address.
⏱ 30 minutesReview your LLC's bank statements for the year. Every incoming wire from you, every outgoing payment to you or a related party, every capital contribution, every loan — document it all. Categorize each transaction using the list above (capital contributions, loans, service payments, etc.). If you transferred $0, note that too — it's still a reportable disclosure.
⏱ 1–2 hoursPart I: Reporting corporation info (LLC name, EIN, address). Part II: Foreign person who is the direct owner (your information). Part III: Related party information if applicable. Part IV: Summary of all reportable transactions with a foreign party. Part V: Detailed listing of each transaction type and dollar amount. Download Form 5472 from irs.gov/pub/irs-pdf/i5472.pdf for full instructions.
⏱ 1–2 hoursAttach Form 5472 to a pro forma Form 1120 (US Corporation Income Tax Return). You do not need to complete every line of Form 1120 — the "pro forma" means it reflects the actual tax situation of a disregarded entity (which is typically $0 tax due for a single-member LLC with no separate entity tax liability). Write Foreign-Owned US Disregarded Entity clearly across the top of the Form 1120 to alert the IRS processor.
Form 5472 cannot be e-filed. Mail to the address specified in the Form 5472 instructions — it depends on where your LLC's principal business is located. Use certified mail with return receipt requested so you have proof of filing. Retain copies of everything. If you are mail-averse, check if your CPA or registered agent offers direct fax submission to the IRS.
⏱ File by April 15If you need more time, file IRS Form 7004 (Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns) by April 15. This extends your filing deadline to October 15. Note: Form 7004 does not extend the time to pay any tax — only to file. For most foreign-owned single-member LLCs, no tax is due, so this is purely an extension of the information filing deadline.
⏱ File by April 15 to qualifyForeign founders often encounter multiple IRS forms. Here's how they differ from Form 5472.
| Form | Who Files It | Purpose | E-File? | Tax Due? |
|---|---|---|---|---|
| Form 5472 | Foreign-owned US LLC/C-Corp (25%+ foreign owner) | Reports transactions with foreign owner | No — mail/fax only | No (information return only) |
| Form 1120 Required | US corporations and foreign-owned single-member LLCs | Corporate income tax return | Yes (if filed separately) | Yes — but usually $0 for disregarded entities |
| Form 1040-NR | Non-resident aliens with US income | Personal income tax on US-sourced income | Yes | Depends on income level |
| Form 1065 | Multi-member LLCs (partnerships) | Partnership income tax return | Yes | No (pass-through entity) |
| Form 1120-S | S-Corporations | S-Corp income tax return | Yes | Pass-through to shareholders |
| Form 5471 | US persons owning 10%+ in foreign corporations | Reports foreign corporation info | No — mail only | No (information return) |
| Form 8865 | US persons who own 10%+ in foreign partnerships | Reports foreign partnership info | No — mail only | No (information return) |
Many foreign founders don't have a US SSN. The IRS explicitly accommodates this — here's exactly how to do it.
Call +1-267-941-1099 (toll-free from outside the US, Mon–Fri, 6am–11pm ET). Have the following ready:
No SSN or ITIN is required. EIN is given over the phone immediately. Write it down — the IRS will not mail a confirmation.
Go to irs.gov/ein and use the EIN Assistant tool. The online tool typically requires a US SSN or ITIN for the "responsible party" — however, non-resident aliens without SSN can often still apply via Form SS-4 fax method. If the online tool rejects you, use the phone method instead.
Complete IRS Form SS-4 (Application for Employer Identification Number). Leave the SSN field blank and write N/A. Fax to the number listed on the form. EIN typically returned within 4 business days. Include a cover letter if faxing from outside the US.
Do not use a US friend's SSN as the "responsible party" EIN applicant unless you are comfortable with them being listed as the responsible party on your LLC's IRS records. The responsible party is the individual who controls, manages, or directs the entity — and this information is reported to the IRS. For a foreign-owned LLC, this should be you.
