International / Form 5472
Foreign-owned single-member LLCs and Form 5472.
If a U.S. limited liability company has one owner and that owner is a foreign person, the company has an annual federal filing requirement. It applies whether or not the LLC earned anything, whether or not it did business in the United States, and whether or not any tax is owed. The penalty for missing it starts at $25,000 per year.
The rule
What the requirement actually is
A disregarded entity stops being disregarded, for this purpose
A single-member LLC is normally invisible for federal tax: its activity is reported by its owner. Regulations effective for tax years beginning in 2017 changed that when the single member is a foreign person. For reporting purposes only, the LLC is treated as a domestic corporation separate from its owner, which pulls it into the related-party reporting rules of Internal Revenue Code section 6038A. Its income tax treatment does not change.
The filing is Form 5472 attached to a pro forma Form 1120
The LLC files a Form 1120 that is largely blank, used only as a cover for the Form 5472, on which the reportable transactions are disclosed. It is not an income tax return and it does not report profit. Per the current instructions it is submitted by mail or fax to the specific IRS service center designated for these filings, not attached to any other return.
An EIN is required, and the owner must be identified
The LLC needs its own employer identification number before it can file, applied for on Form SS-4 with a responsible party named. A foreign responsible party without a U.S. taxpayer identification number cannot use the online application and applies by fax or mail instead. This step is often what delays everything else.
“No activity” is rarely true
Reportable transactions include far more than sales. Money the owner contributes to the LLC, money the LLC distributes back, amounts paid on the LLC’s behalf, formation costs, loans, rent, interest, and services between the LLC and its owner or other related parties all count. A newly formed LLC that received a single capital contribution and paid a registered agent has reportable transactions.
Records have to exist, not just the form
Section 6038A also requires the entity to keep records sufficient to establish the correctness of the reported transactions. A separate bank account and clean books between the LLC and its owner are what make that possible. Commingled funds are the usual reason a filing cannot be prepared accurately after the fact.
How the work goes
From formation documents to a filed return.
- Confirm statusEstablish ownership, entity classification, and which years are open.
- Obtain the EINApply on Form SS-4 by the route available to a foreign responsible party.
- Reconstruct transactionsIdentify every reportable transaction with the owner and related parties.
- File and documentSubmit the Form 5472 and pro forma 1120, and set up records for next year.
Deadlines and penalties
What it costs to be late
The deadline follows the corporate return
The pro forma Form 1120 with Form 5472 is due on the same schedule as a corporate return, generally the fifteenth day of the fourth month after the end of the tax year, which is April 15 for a calendar-year entity. A six-month extension is available on Form 7004, but the extension has to be filed on time to count.
The penalty is $25,000 per form, per year
Failure to file a required Form 5472, or failure to maintain the required records, carries a $25,000 penalty. If the failure continues after the IRS gives formal notice, an additional $25,000 applies for each 30-day period the failure continues. Three unfiled years is a $75,000 starting position, not a rounding error.
Reasonable cause is a real defense, but it has to be built
The penalty can be abated for reasonable cause, and late filings are routinely resolved. What matters is the quality of the explanation and the completeness of the filings submitted with it. Filing quietly and hoping is usually worse than filing with a statement. See penalty abatement.
This is not the only filing to check
Depending on facts, the same owner may also owe a Form 1040-NR if the LLC has effectively connected income, state registrations and returns where the LLC operates, sales tax registration, and withholding obligations on payments. Beneficial ownership reporting under the Corporate Transparency Act has changed repeatedly since 2024, so confirm the current requirement rather than relying on older guidance.

Questions
Common questions
My LLC had no income at all. Do I still have to file?
Almost certainly yes. The requirement is triggered by reportable transactions with related parties, not by income. Contributing capital to the LLC is itself a reportable transaction, as is paying formation or registered agent costs from the owner’s funds. An LLC with no revenue that received a single wire from its owner has something to report.
Does filing Form 5472 mean the LLC owes U.S. tax?
No. Form 5472 is an information return. Whether tax is owed depends on whether the LLC has income effectively connected with a U.S. trade or business, or U.S.-source income subject to withholding, which is a separate analysis handled on Form 1040-NR or another return.
Can I file this myself with my regular tax software?
Generally not. This is a pro forma Form 1120 used as a cover sheet for Form 5472, submitted to a designated IRS address by mail or fax. Consumer software does not produce it, and the combination is easy to get wrong in ways that leave the penalty exposure open.
The LLC has been open for four years and never filed anything. What now?
Bring the filings current for all open years and submit them with a reasonable cause statement rather than filing silently. The exposure is real but so is the relief, and the IRS treats a complete, self-corrected package very differently from a filing produced after it sends a notice.
What if the LLC has two foreign owners instead of one?
Then it is a partnership by default, not a disregarded entity, and the rules change: it files Form 1065 with Schedules K-1, may owe withholding on effectively connected income allocable to foreign partners, and may have Form 8804 and 8805 obligations. Different forms, same principle that the filings do not depend on profit.
Fix the filing before the IRS asks.
If the LLC has never filed, or you are not sure whether it should have, send us the formation documents and the bank activity. We will tell you what is open and what it takes to close it.
