Form 5472 Line-by-Line: Filing for a Foreign-Owned LLC
If you formed a US single-member LLC from outside the country, the IRS treats it as a domestic corporation for one purpose: informational reporting under IRC 6038A. That means filing Form 5472 every year with a pro-forma Form 1120, even when the LLC earned nothing. The penalty starts at $25,000 per form, per related party. This is not a tax return -- it is an information return, and it applies whether or not your LLC has income or owes US tax.
As a federally licensed Enrolled Agent working with non-resident founders internationally, Form 5472 is the filing most have never heard of. This post walks through how the form gets filed and where the common mistakes are. This is general information, not individual tax or legal advice. For the broader compliance stack, see our guide on US taxes for a non-resident LLC and Form 5472.
Who Must File
Two categories trigger Form 5472: a US corporation that is 25% or more foreign-owned, or a foreign-owned disregarded entity -- typically a single-member US LLC whose sole member is a nonresident alien or foreign corporation. The second category catches foreign founders off guard. Under T.D. 9796, effective for tax years beginning on or after January 1, 2017, a foreign-owned single-member US LLC is treated as a domestic corporation for IRC 6038A reporting only. The LLC remains disregarded for income tax -- it does not file its own income tax return -- but it must file Form 5472 and a pro-forma 1120.
If your LLC has a US citizen or resident as its sole member, Form 5472 does not apply. The trigger is foreign ownership of 25% or more.
The Pro-Forma Form 1120 Cover Sheet
Every Form 5472 is filed with a pro-forma Form 1120. You are not computing corporate tax -- the 1120 is a cover sheet so the IRS has a place to attach the 5472. For a disregarded entity, it typically shows the LLC's identifying information at the top and zeros on the income lines, because the LLC's income and expenses are reported on the owner's return (if the owner has ECI) or not at all. For getting an EIN, see our guide on forming a US LLC and getting an EIN without an SSN.
Part I: Identifying the Reporting Corporation
Part I asks for basic identifying information. For a foreign-owned disregarded LLC, the "reporting corporation" is the LLC itself: legal name, EIN, address, principal place of business, and tax year. The address and EIN must match what the IRS has on file from the SS-4 application -- a mismatch is a common rejection trigger.
Parts II and III: The Foreign Owner and the Related Party
Part II identifies the 25% foreign shareholder -- for a single-member LLC, the sole foreign owner at 100%: name, address, country of organization or citizenship, and a US taxpayer identification number if one exists (a foreign reference ID is used when there is none). When the LLC is owned through a foreign corporation or a chain of entities, the ultimate indirect 25% foreign shareholder is identified here too. Part III identifies the related party that transacted with the LLC during the year -- for most foreign-owned single-member LLCs, the same person as Part II: the owner.
Parts IV and V: Reporting the Transactions
This is the heart of the form. Part IV reports monetary transactions with the foreign related party -- sales, rent, royalties, interest, loan balances. Part V covers transactions specific to a foreign-owned disregarded entity, and this is where most single-member LLC activity lands: amounts paid or received in connection with forming, dissolving, acquiring, or disposing of the entity, including capital contributions and distributions. Reportable transactions:
Capital contributions from the foreign owner (including initial bank account funding)
Distributions from the LLC to the foreign owner
Loans between the LLC and the foreign owner
Payments for services, rent, or royalties
The part that surprises people: funding the LLC's bank account is itself a reportable transaction. Under the regulations at Treas. Reg. 1.6038A-2, contributions to and distributions from a foreign-owned disregarded entity are reportable -- they belong in Part V. This is why "no income, no filing" is wrong -- the trigger is any reportable transaction, and putting money into the company counts. If there were zero transactions during the year, the form is still filed with zeros in Part II.
we will check whether your Form 5472 is set up correctly and whether your foreign-owned LLC has any gaps in its US compliance.
Part VI and Filing Mechanics
Part VI covers nonmonetary and less-than-full-consideration transactions -- rare for a simple holding or services LLC, but it exists. One mechanic catches filers off guard: a foreign-owned disregarded entity cannot e-file this package. The pro-forma 1120 with Form 5472 attached goes to the IRS by fax or mail to its dedicated Ogden, Utah intake.
Common Mistakes That Trigger the $25,000 Penalty
The penalty under IRC 6038A(d) starts at $25,000 per form, per related party, for failure to file, late filing, or substantially incomplete filing. If the failure continues 90 days after IRS notice, an additional $25,000 can be imposed for each 30-day period. The penalty was raised from $10,000 to $25,000 by the TCJA for tax years beginning after 2017. The 5472 penalty is not abatable through first-time penalty abatement.
The mistakes I see most often: not filing because the LLC had no income (the trigger is foreign ownership, not revenue); filing the 1120 but omitting the 5472; using the wrong deadline (calendar-year LLCs file April 15, or October 15 on Form 7004 extension); reporting net deposits instead of gross; and not obtaining an EIN first. For the full penalty breakdown, see our guide on the Form 5472 and $25,000 penalty for foreign-owned LLCs.
When a Treaty Position Interacts With 5472
A tax treaty can reduce US income tax on business profits when a foreign founder has no US permanent establishment. That is separate from Form 5472 -- an information return under IRC 6038A is not waived by a treaty. If your treaty position means you file Form 1040-NR with a Form 8833, you still file the 5472 and pro-forma 1120. A treaty changes what income tax you owe, not whether the 5472 is due.
