What Is IRS Form 5472?
IRS Form 5472 is titled "Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business." For foreign-owned single-member LLCs, it functions as an information return — not a tax return in the traditional sense. You are not reporting income or calculating tax owed on Form 5472 itself. You are reporting financial transactions between the LLC and its foreign owner.
This is a critical distinction: Form 5472 is required even if your LLC had zero income, zero expenses, and zero activity — as long as any of the reportable transactions described below occurred. And in almost every foreign-owned LLC, at least one of these transactions occurs every year (typically the owner contributing money to fund the LLC's formation).
The IRS treats foreign-owned single-member LLCs as corporations for Form 5472 purposes — which is why the filing includes a pro forma (skeleton) Form 1120, the US corporate income tax return. The LLC does not pay corporate tax, but it must file a minimal version of the 1120 as a "wrapper" for the 5472.
What Is the Pro Forma Form 1120 and Why Is It Required?
The pro forma Form 1120 is a corporate tax return filed with minimal information, specifically to serve as the required attachment for Form 5472. A foreign-owned single-member LLC is not a corporation — but for Form 5472 filing purposes, the IRS treats it as one. The pro forma 1120 includes:
LLC name, EIN (Employer Identification Number), address, and tax year. The LLC's EIN — obtained via IRS Form SS-4 — is required here. You cannot file without an EIN.
For most disregarded-entity single-member LLCs with foreign owners, all income lines show $0. The LLC's income passes through to the foreign owner and is not subject to US corporate tax. These lines confirm the LLC had no US-sourced income taxable at the corporate level.
A simplified balance sheet showing beginning and ending assets, liabilities, and equity. This is where total assets, bank balances, and owner's equity are reported. Common errors: leaving this blank, or failing to reconcile beginning and ending balances with the transactions reported on Form 5472.
The completed Form 5472 is attached to the pro forma 1120 as an exhibit. Together, both forms are mailed to the IRS. This combined filing must be mailed — there is currently no electronic filing option for this submission.
What Is a "Reportable Transaction" — The Key Trigger
Form 5472 is required when your LLC has "reportable transactions" with its foreign owner or related parties. Understanding what counts as a reportable transaction is essential because almost every foreign-owned LLC has at least one every year:
💰 Capital Contributions
Money you transfer into the LLC from your personal funds to fund its operations, formation costs, or purchases. This is the most common reportable transaction — it occurs every time the owner sends money to the LLC's bank account.
💸 Distributions
Money the LLC distributes back to the foreign owner. This includes profit withdrawals, owner draws, or any transfer of LLC funds back to the owner's personal account.
🏦 Loans
Any loan from the owner to the LLC, or from the LLC to the owner. The outstanding principal and interest are reportable. Even interest-free loans between the owner and LLC are reportable transactions.
🏠 Property Transfers
Transfer of any property (equipment, intellectual property, real estate) from the owner to the LLC or vice versa. Any sale, purchase, or lease of property between the owner and the LLC is reportable.
🔧 Services Rendered
Services provided by the owner to the LLC (without arm's-length compensation), or services provided by the LLC to the owner. This includes owner labor, management services, and professional services between related parties.
✓ Zero-Transaction Exception
The only situation where Form 5472 might not be required: the LLC had absolutely no reportable transactions with its foreign owner or any related parties during the entire tax year. This is extremely rare for an active LLC — even formation funding is a reportable transaction.
Deadline and Filing Method
March 31 — Annual Deadline
Form 5472 (attached to pro forma Form 1120) must be received by the IRS by March 31 of the year following the tax year in question. For the 2024 tax year, the deadline is March 31, 2025. If March 31 falls on a weekend, the deadline moves to the next business day. Extensions are available but must be requested by the original deadline — a 6-month extension (to September 30) can be requested by filing Form 7004. The extension extends the time to file, not the time to pay any tax that may be due.
How to File Form 5472 and Pro Forma 1120
Confirm your LLC's EIN
You must have an Employer Identification Number (EIN) to file Form 5472. If your LLC does not yet have an EIN, you need to apply via IRS Form SS-4 before you can file. See our EIN for Foreigners guide for the complete process. The EIN appears on the top of both Form 5472 and the pro forma 1120.
Gather your reportable transaction data
Collect records of all transactions between you (the foreign owner) and the LLC during the tax year: capital contributions (money you sent to the LLC), distributions (money you withdrew), any loans, property transfers, or services. This data is reported in Part IV of Form 5472. Your LLC's bank statements are the primary source for this information.
Complete the pro forma Form 1120
Prepare a minimal Form 1120 with the LLC's identifying information, a balance sheet (Schedule L), and all income lines typically showing $0. This form is filed pro forma — it does not create a tax liability but is required as the vehicle for attaching Form 5472. The pro forma 1120 must have "Foreign-Owned U.S. DE" written across the top of the form.
Complete Form 5472
Fill out Form 5472 with: Part I (LLC identification, EIN), Part II (foreign owner's information including country of residence, FTIN if applicable), Part III (type of reportable transactions), and Part IV (monetary amounts for each reportable transaction). Accuracy matters — errors in Part IV amounts are a common audit trigger.
Attach Form 5472 to Form 1120 and mail
Form 5472 is attached as an exhibit to the pro forma 1120 and mailed (no e-file available) to: Internal Revenue Service, 1973 North Rulon White Blvd, Ogden, UT 84201. Use certified mail and retain the tracking receipt as proof of timely filing. The postmark date determines timely filing.
The Form 5472 Penalty: How the IRS Assesses $25,000
The $25,000 Form 5472 penalty is codified in IRC Section 6038A(d). Here is exactly how it works:
| Situation | Penalty Amount |
|---|---|
| Failure to file Form 5472 by March 31 | $25,000 per form per tax year |
| Failure to file and non-compliance continues after IRS notice | Additional $25,000 for each 90-day period of continued non-compliance |
| Failure to maintain required records | $25,000 per occurrence |
| Multiple missed years (e.g., 3 years) | $75,000 minimum ($25,000 × 3) — assessed automatically |
| Reasonable cause exception | Penalty may be waived if taxpayer demonstrates reasonable cause — but IRS applies this narrowly |
What to Do If You Already Missed the Form 5472 Deadline
If you have already missed the March 31 deadline for one or more years, acting quickly reduces your total exposure:
File immediately — do not wait
The $25,000 penalty accrues per tax year. Every year you wait is another $25,000. File the delinquent Form 5472 and pro forma 1120 as soon as possible, even if it is late. Late filing reduces further accumulation and demonstrates good faith to the IRS.
Consider IRS Delinquent Returns procedures
The IRS has formal procedures for voluntary disclosure of delinquent information returns. A properly filed delinquent return with a reasonable cause statement may qualify for penalty abatement under IRC 6038A(d)(2). No guarantee — but demonstrated good faith significantly improves outcomes.
Request a penalty abatement
After filing delinquent returns, submit a written penalty abatement request to the IRS explaining the circumstances. First-time penalty abatement (FTA) relief is available if you had a clean compliance history prior to the missed year. IRS Revenue Procedure 84-35 may apply in some circumstances.
Work with a qualified tax professional
Delinquent Form 5472 situations benefit from professional guidance. Monezzi's Form 5472 filing service includes prior-year delinquent filings and the relevant penalty abatement correspondence where applicable.
Common Form 5472 Mistakes That Trigger IRS Attention
- Not filing at all — The most common and expensive mistake. Many foreign LLC owners are never told about this requirement by their LLC formation service.
- Filing Form 5472 without the pro forma 1120 — Form 5472 must be attached to Form 1120. A standalone 5472 is not a valid filing.
- Incorrect amounts in Part IV — Inconsistencies between the 5472 transaction amounts and the balance sheet on Schedule L of Form 1120 are a red flag. Reconcile your beginning and ending balances.
- Missing or incorrect FTIN — The foreign owner's Foreign Tax Identification Number (e.g., Turkey's T.C. Kimlik No., Germany's Steuernummer, UAE's TRN) should be included in Part II of Form 5472. If unavailable, write "FOREIGNUS."
- E-filing instead of mailing — The pro forma 1120/5472 package cannot be e-filed. It must be mailed to the IRS Ogden, Utah address.
- Missing the "Foreign-Owned U.S. DE" notation — The pro forma 1120 must have "Foreign-Owned U.S. DE" written across the top. Without this, the IRS may process it as a full corporate return.
- Not keeping supporting records — The IRS can request documentation supporting the amounts reported on Form 5472. Bank statements, wire transfer records, and bookkeeping records should be maintained for at least 6 years.

IRS Form 5472 — Frequently Asked Questions
Who needs to file IRS Form 5472?
Any single-member LLC that (1) is treated as a disregarded entity for US tax purposes, (2) is owned by a non-US person (foreign individual or foreign entity), and (3) had reportable transactions with its foreign owner during the tax year. This applies to LLC owners from every country — Turkey, Germany, UAE, Mexico, India, Brazil, and all others. The requirement applies regardless of whether the LLC had income, regardless of how much was in the bank account, and regardless of whether the LLC did any business.
What happens if I don't file Form 5472?
The IRS assesses a $25,000 minimum penalty per Form 5472 per tax year under IRC Section 6038A(d). If you have multiple missed years, penalties accumulate: 2 years = $50,000 minimum, 3 years = $75,000 minimum. If the IRS discovers the failure and issues a notice and you still do not file, an additional $25,000 penalty is assessed for each 90-day period of continued non-compliance. The IRS does not send advance warning reminders — penalties are assessed retroactively upon discovery.
Does Form 5472 apply if my LLC had zero income?
Yes. Form 5472 is required based on reportable transactions between the LLC and its foreign owner — not based on income. The most common reportable transaction is a capital contribution (money the owner transfers to fund the LLC). This transaction occurs every time the owner sends money to the LLC's bank account — including the initial formation funding. Zero income does not mean zero filing obligation. Only an LLC with absolutely no transactions whatsoever between the LLC and its foreign owner has no Form 5472 obligation — an extremely rare situation for any active LLC.
What is the deadline for Form 5472?
The Form 5472 (attached to pro forma Form 1120) is due March 31 of the year following the tax year. For tax year 2024, the deadline is March 31, 2025. A 6-month extension can be requested by filing Form 7004 by the original March 31 deadline, extending the due date to September 30. Monezzi tracks the Form 5472 deadline for all clients and sends reminders before the deadline each year.
What is a reportable transaction for Form 5472 purposes?
A reportable transaction is any financial exchange between the US LLC and its foreign owner (or related parties): capital contributions (owner funding the LLC), distributions (LLC paying owner), loans in either direction, property transfers, and services. These transactions are reported in Part IV of Form 5472 with dollar amounts. The obligation to file Form 5472 exists whenever any of these transactions occurred during the tax year — regardless of amounts or whether the LLC had outside revenue.
What is the Form 1120 that accompanies Form 5472?
Foreign-owned single-member LLCs must file Form 5472 attached to a pro forma ("skeleton") Form 1120 — the US corporate income tax return. The pro forma 1120 is prepared with minimal information: the LLC's EIN, name, address, and a basic balance sheet (Schedule L). Income lines typically show $0. The LLC does not pay corporate tax, but the 1120 serves as the required "wrapper" for Form 5472. The top of the Form 1120 must be marked "Foreign-Owned U.S. DE" (Disregarded Entity). Filing Form 5472 alone without the attached 1120 is not a valid filing.
Can I e-file Form 5472?
No. The pro forma Form 1120 with Form 5472 attached must be mailed to the IRS — electronic filing is not currently available for this specific submission. The mailing address is: Internal Revenue Service, 1973 North Rulon White Blvd, Ogden, UT 84201. Use certified mail with return receipt to have documented proof that the filing was received. The postmark date determines whether the filing was made by the deadline.
I have missed Form 5472 for multiple years. What should I do?
File all delinquent Form 5472 and pro forma 1120 packages as soon as possible. For each missed year, prepare a separate complete filing. Include a reasonable cause statement explaining why the returns were not timely filed — this creates a record for potential penalty abatement consideration. After filing, submit a written penalty abatement request to the IRS. Monezzi handles prior-year delinquent 5472 filings and prepares the accompanying penalty abatement correspondence.
If you own a US LLC as a non-US resident, you are required to file IRS Form 5472 with a pro forma Form 1120 every year by March 31. The minimum penalty for failure to file is $25,000 per form per year — assessed automatically, without advance warning. The obligation exists regardless of income, and the most common reportable transaction (capital contribution) happens the moment you fund your LLC.
