If you’re involved with a U.S. company that has any foreign ownership, there’s a form you probably don’t know about but absolutely need to know about. It’s called Form 5472, and the penalties for missing it are severe enough to bankrupt the business.
This isn’t about your personal foreign accounts. This is about U.S. companies being owned or controlled by foreign persons. Think of it as the IRS’s surveillance form for cross-border money movements.
If you have a U.S. business entity, most commonly a Limited Liability Company (LLC), and 25% or more of it is owned by a “foreign person,” then you almost certainly need to file Form 5472. The ownership test is the key.
A “foreign person” isn’t just an individual living abroad. The IRS defines it broadly as:
- A non-U.S. citizen who is not a resident alien (a “nonresident alien”)
- A foreign corporation
- A foreign partnership
- A foreign estate or trust
- Even a U.S.-based LLC that is itself owned by a foreign person
The ownership is measured by voting power or value. If a foreign person owns 25% or more of either, the reporting requirement is triggered.
Example 1: The Family Investment
A father in Canada gifts $100,000 to his son, a U.S. green card holder living in Florida. The son uses the money to start a Florida LLC for a roofing business. The father takes a 30% ownership stake in exchange for the seed capital.
- Result: The Florida LLC now has a “25% foreign shareholder.” The LLC must file Form 5472 annually, reporting any transactions with the father.
Example 2: The Startup with Foreign Investors
Three U.S. citizens in Silicon Valley start a Delaware C-Corporation. They get a $2 million investment from a German venture capital fund. The fund takes a 30% equity stake and a board seat.
- Result: The Delaware corporation has a “25% foreign shareholder.” The corporation must file Form 5472.
Example 3: The Disregarded Entity Trap (The Most Common Miss)
A single individual who is a citizen and resident of Japan forms a Texas LLC to run an e-commerce business selling in the U.S. She is the 100% owner. For U.S. tax purposes, this single-member LLC is a “disregarded entity.”
- Result: This is the biggest trap. Even though the LLC is “disregarded” and files no separate U.S. tax return, it is still a “reporting corporation” for Form 5472 purposes. It must obtain an EIN and file Form 5472 annually, reporting all its transactions with its Japanese owner.
What Exactly Are You Reporting?
Form 5472 is an information return. You’re not calculating tax on it. You’re listing every single financial transaction between the U.S. company and its foreign owner or related foreign parties.
You have to report any “reportable transaction” which includes:
- Sales or purchases of inventory, stock in trade, or tangible property
- Sales, purchases, rents, or leases of intangible property (licenses, patents, royalties)
- Loans, debts, or advances (this is huge, even a simple loan from the owner to the company)
- Interest payments
- Services (management fees, consulting fees, commissions)
- Any other monetary consideration
You need to report the total amount of money that flowed each way during the tax year for each category.
This is not a trivial form. The penalties are corporate-level and automatic.
- Failure to File: $25,000 penalty.
- Continued Failure After IRS Notice: An additional $25,000 penalty for each 30-day period the failure continues. There is no maximum penalty.
These penalties are assessed on the U.S. company, not the foreign owner. They can be imposed even if no U.S. tax was due. The IRS can also disallow related deductions.
The Filing Process & Deadlines
- Who Files: The U.S. company (the “reporting corporation”) files the form. It must have a U.S. Employer Identification Number (EIN).
- When to File: Form 5472 is filed as an attachment to the company’s annual U.S. income tax return.
- For a C-Corp (Form 1120): Due by the 15th day of the 4th month after year-end (April 15 for calendar-year).
- For a Disregarded Entity (like a foreign-owned SMLLC): This is critical. The disregarded entity must file its own Form 1120, “U.S. Income Tax Return of a Foreign Corporation” just to have something to attach the Form 5472 to. This is a zero-tax return purely for reporting. It’s due by the 15th day of the 6th month after year-end (June 15 for calendar-year).
- Where to File: With the appropriate IRS Service Center where the tax return is filed.
Frequently Asked Questions (FAQ)
Our foreign owner owns 24%. Do we need to file?
No, you are under the 25% threshold. But monitor this closely. If the ownership percentage ticks up to 25% at any time during the tax year, the requirement is triggered for that entire year.
What if the foreign owner is completely passive? No money moves between us.
You still must file Form 5472. You would report “N/A” or zero for the transaction amounts, but the form itself is still required to be filed to disclose the ownership relationship. Failure to file because there were no transactions is not a valid excuse and will still trigger the $25,000 penalty.
Our company is owned by a U.S. LLC, but that U.S. LLC is owned by a foreign person. Does this trigger Form 5472?
Yes, very likely. Ownership is traced through intermediate entities. If a foreign person owns 25% or more of the U.S. parent LLC, and that parent LLC owns your company, the foreign person is considered an indirect 25% owner of your company. Your company likely has a filing requirement.
Can we e-file Form 5472?
Generally, no. Form 5472 must be filed as a paper attachment to the related tax return (Form 1120 or 1065). You cannot e-file it separately. The entire return package must be mailed.
We missed filing for the past three years. What do we do?
You need to get into compliance immediately. This usually involves:
1. Preparing and filing the delinquent Forms 1120 (for disregarded entities) or the applicable business return for each missed year.
2. Attaching a complete Form 5472 for each year.
3. Including a “Reasonable Cause” statement explaining the failure, asserting it was not willful neglect, and showing you have now implemented procedures to comply.
You should engage a tax professional experienced in IRS international penalty relief to guide this process. The IRS’s Delinquent International Information Return Submission Procedures may apply.
Is there a minimum transaction amount to report?
No. The form instructions do not provide a de minimis exception. All reportable transactions, regardless of size, must be reported in the aggregate for each category.
Does this replace other forms, like FBAR or Form 8938?
No, it’s completely separate and additional. The foreign owner may have personal FBAR/8938 filing requirements for their own accounts. The U.S. company may have other forms (like Form 8858 if it has foreign subsidiaries). Form 5472 is a specific reporting requirement for the U.S. entity itself.
The Bottom Line: If there’s any foreign ownership in your U.S. company, your first call should be to a tax pro to answer the Form 5472 question. Do not rely on your bookkeeper or the foreign owner’s accountant abroad, most have no idea this U.S.-specific requirement exists. The cost of preparing the form is a fraction of the penalty for missing it. Assume you need it until proven otherwise.
