IRS Form 5472 filing solution — step-by-step guide for foreign-owned U.S. LLCs in 2026


The Solution — At a Glance

If you own a U.S. LLC as a non-U.S. resident, your Form 5472 solution is: file Form 5472 attached to a pro-forma Form 1120 by April 15 (October 15 with extension). Report every transaction between you and the LLC. Have it signed by a U.S.-licensed CPA or Enrolled Agent. Fax or mail to the IRS — it cannot be e-filed. Missing this triggers an automatic $25,000 penalty per form. The purpose-built solution for foreign LLC owners is Form5472.online — $448 flat, signed by a Virginia-licensed CPA.signed by a Virginia-licensed CPA.



Who Needs This Solution

You need a Form 5472 filing solution if you are a non-U.S. person who owns 25% or more of a U.S. entity and had any "reportable transaction" with that entity during the tax year. In practice, this means almost every foreign founder of a U.S. LLC needs to file — every year.

Your Situation

Must File Form 5472?

Foreign-owned single-member LLC (SMLLC) with any transaction

✓ Yes — every year

Foreign-owned multi-member LLC with foreign partners

✓ Yes — for each foreign partner

U.S. corporation with 25%+ foreign ownership

✓ Yes — attached to Form 1120

LLC with zero revenue but owner contributed capital

✓ Yes — capital contribution = reportable transaction

LLC formed but no activity and no transactions of any kind

Consult a CPA — edge case

Zero income ≠ zero filing obligation. The most common mistake: founders assume that if their LLC made no money, nothing needs to be filed. Form 5472 is triggered by transactions — not revenue. If you contributed money, paid a business expense from your personal account, or moved any funds through the LLC, you have a reportable transaction.




The Complete Form 5472 Solution: 6 Steps

STEP 1

Confirm Your Entity Type and Filing Requirement

Different entity types use Form 5472 differently. Identify yours before you begin:

  • Single-Member LLC (disregarded entity): File Form 5472 attached to a pro-forma Form 1120. The LLC pays no income tax but still files as an information return.

  • Multi-Member LLC (treated as partnership): File Form 5472 with Form 1065. A separate Form 5472 is required for each foreign partner with reportable transactions.

  • LLC taxed as C-Corp (check-the-box election): File Form 5472 attached to a full Form 1120.

  • U.S. corporation (foreign-owned): File Form 5472 as part of your regular Form 1120.


STEP 2

Get Your EIN (Employer Identification Number)

Form 5472 requires your LLC's U.S. Employer Identification Number (EIN). If you don't have one, apply using Form SS-4. Foreign owners without a U.S. Social Security Number must apply by fax or mail — the online EIN application is not available to foreign applicants without a U.S. TIN. Processing can take 4–8 weeks by fax.


Get your EIN early. You cannot file Form 5472 without one. If you're close to the deadline and don't have an EIN, apply immediately and document the application as evidence of good-faith compliance.


STEP 3

Identify and Document All Reportable Transactions

A reportable transaction is any movement of money, property, or services between you (the foreign owner) and the U.S. LLC. This includes:

  • Capital contributions: money you put into the LLC bank account

  • Distributions / withdrawals: money you took out of the LLC

  • Loans: money you lent to the LLC, or the LLC lent to you

  • Expense reimbursements: business expenses you paid personally and were reimbursed for

  • Services: work you performed for the LLC for compensation

  • Rents: property you rented to or from the LLC

  • Royalties and licensing fees

  • Formation and dissolution costs paid on behalf of the LLC

Gather bank statements, transaction records, and any intercompany agreements. All amounts must be reported in U.S. dollars.


STEP 4

Prepare Form 5472 and the Pro-Forma Form 1120

Form 5472 has five parts. Here is what goes in each:

  • Part I — Reporting Corporation: Your LLC's name, EIN, address, and tax year.

  • Part II — Foreign Related Party: Your name or entity name, country of residence, and taxpayer identification number (if applicable).

  • Part III — Monetary Transactions: Dollar amounts for each type of reportable transaction — sales, rents, royalties, interest, services, etc.

  • Part IV — Nonmonetary and Less-Than-Full-Consideration Transactions: Property transfers and other non-cash transactions.

  • Part V — Foreign Related Corporations: Required if the related party is a foreign corporation.


For a single-member LLC, you also need a pro-forma Form 1120 — a skeleton version of the U.S. corporate return. You complete only the identifying information (name, address, EIN, tax year, signature). Leave all income and expense lines blank. Form 5472 is attached to this pro-forma return as a single package.


STEP 5

Have It Signed by a U.S.-Licensed CPA or Enrolled Agent

IRS Circular 230 requires that tax returns filed with the IRS be signed by a qualified practitioner: a U.S.-licensed CPA, Enrolled Agent (EA), or U.S.-admitted attorney. Foreign accountants — regardless of their credentials — cannot sign IRS forms.

⚠ Do not sign Form 5472 yourself as a "self-preparer." The IRS has increased scrutiny of self-prepared Form 5472 submissions from foreign owners. A return signed by an unqualified preparer may be treated as unsigned — triggering the $25,000 penalty as if no return was filed.



STEP 6

Submit to the IRS — Fax or Certified Mail Only

Form 5472, when filed as a standalone pro-forma package (for a disregarded entity), cannot be e-filed. Submit by:

  • Fax: 855-887-7737 (IRS dedicated line for Form 5472 pro-forma packages)

  • Certified mail: Internal Revenue Service, Ogden, UT 84201-0012

Send the Form 5472 and pro-forma Form 1120 as one package. Keep proof of submission — the fax confirmation or USPS certified mail receipt. The IRS does not send an acknowledgment of receipt for these filings.


Keep your fax confirmation. If the IRS claims non-receipt and you cannot prove you filed, you have no defense against the penalty. The burden of proof is on the filer.




Deadlines and Extensions

Entity Type

Standard Deadline

Extended Deadline

Extension Form

Single-Member LLC / C-Corp

April 15

October 15

Form 7004

Multi-Member LLC (partnership)

March 15

September 15

Form 7004



⚠ File Form 7004 before the original deadline to get the extension. If you miss April 15 without filing a Form 7004, you have no extension — and the $25,000 penalty clock starts from April 15.




The Penalty — and How to Fix Missed Years

The penalty for failing to file Form 5472 is $25,000 per form, per year — assessed automatically, with no income minimum and no grace period. If the IRS issues a notice and the form remains unfiled for 90 days, a further $25,000 applies for every additional 30-day period.


Missed Prior Years: DIIRSP

If you have missed one or more years, the IRS has a voluntary disclosure path: the Delinquent International Information Return Submission Procedures (DIIRSP). Under DIIRSP, you file all missing returns with a statement explaining the reasonable cause for non-compliance. Coming forward before the IRS contacts you can eliminate or substantially reduce the penalties.



DIIRSP is only available before IRS contact. Once you receive a penalty notice, the voluntary window closes for that tax year. If you have missed years, act now — not after the notice arrives.

Frequently Asked Questions


Can I file Form 5472 myself without a CPA?

Technically, yes — there is no legal bar on self-preparation. In practice, it is high-risk. The form is complex, the pro-forma Form 1120 structure is non-obvious, and a self-prepared return with errors can still trigger the full $25,000 penalty. Most importantly, a return that is incorrectly assembled (e.g., Form 5472 not attached to Form 1120) may be treated by the IRS as not filed at all.


Does Form 5472 need to be filed if my LLC had no income?

If there were reportable transactions — including a capital contribution you made when you set up the LLC — yes, you must file. A truly dormant LLC with no transactions of any kind is an edge case; if you're unsure, consult a CPA rather than assuming you're exempt.


Can Form 5472 be filed electronically?

No — not when filed as a standalone pro-forma package for a disregarded entity. It must be faxed (855-887-7737) or mailed to the IRS. Some software can include Form 5472 as part of a full Form 1120 e-filing for C-Corps, but the standalone SMLLC route requires fax or mail.


How long does Form 5472 filing take?

With a U.S. CPA specialist: 3–5 business days once your information is submitted. Total calendar time from start (gathering your transaction records) to IRS submission is typically 1–2 weeks.


What is the difference between Form 5472 and Form 5471?

Form 5471 is filed by U.S. persons who own foreign corporations. Form 5472 is the reverse: filed by foreign persons who own U.S. corporations or disregarded entities. They are entirely different forms for opposite ownership directions.
