Form 5472: The $25,000 Filing You Cannot Skip
If you own a US single-member LLC as a foreigner, you almost certainly must file Form 5472 with a pro-forma 1120 every year, even at zero revenue. It is an information report, not a tax payment, and skipping it carries a $25,000 penalty. Here is who must file, what, and by when.
The Short Answer
If you are a foreign owner of a US single-member LLC, you almost certainly must file Form 5472 together with a pro-forma Form 1120 every single year, even if the LLC made zero dollars. This is not about paying tax. It is an information report, and skipping it carries a $25,000 penalty per year. It is the single most overlooked obligation for non-resident founders, and the most expensive to ignore.
Why This Applies to You
A foreign-owned single-member LLC is a disregarded entity for US tax. Since 2017, the IRS treats these LLCs as reportable corporations for information purposes, so they must file Form 5472 to disclose transactions between the LLC and its foreign owner. Contributions you make and distributions you take both count as reportable transactions, even moving your own money in and out.
What You Actually File
- Form 5472. Discloses the foreign owner and the reportable transactions.
- A pro-forma Form 1120. Only the top identifying section is completed, with "Foreign-owned US DE" written across the top.
- Together, by fax or mail. This package cannot be e-filed.
- An EIN is required to file, which is one more reason to get it early.
The trap: founders assume that no revenue means no filing. Wrong. The 5472 is an information return, decoupled from whether you owe tax. Zero income, zero US customers, still required. The $25,000 penalty applies to the failure to file, not to any tax due.
Deadlines and Extensions
The filing is due April 15 for a calendar-year LLC. You can extend to October 15 by filing Form 7004 before the April deadline. Miss it entirely and the penalty starts at $25,000, with more for continued non-compliance after IRS notice.
Do You Also Owe US Tax?
Filing the 5472 is separate from owing tax. If your LLC has no US-effectively-connected income, you may owe zero US federal income tax while still being required to file the 5472. If you do have US-connected income, a full return (1040-NR, and possibly others) comes into play. When in doubt, a US CPA who handles foreign-owned LLCs is worth the fee, because the penalty dwarfs their cost.
When This Doesn't Apply
- Your LLC has US members who are US persons in a way that changes its classification. Different rules apply, confirm with a CPA.
- You elected corporate taxation (C-corp). Then you file a real 1120, not the pro-forma package.
- Multi-member LLC. A partnership files Form 1065 instead, with its own foreign-partner rules.
- You genuinely have no LLC. No entity, no 5472. But if you have the LLC, assume you must file.
Frequently Asked Questions
Do I have to file Form 5472 with no income?
Yes. Form 5472 is an information return, not a tax payment. A foreign-owned single-member US LLC must file it with a pro-forma 1120 every year even at zero revenue and zero US customers. The $25,000 penalty is for failing to file, regardless of tax owed.
What is the penalty for not filing?
$25,000 per year, and it can increase for continued non-compliance after the IRS issues a notice. It is the most expensive mistake a non-resident LLC owner can make.
When is Form 5472 due?
April 15 for a calendar-year LLC. You can extend to October 15 by filing Form 7004 before April 15. The package cannot be e-filed, it goes by fax or mail.
Does filing 5472 mean I owe US tax?
No. Filing is separate from owing. If your LLC has no US-effectively-connected income you may owe zero US federal tax while still being required to file the 5472 information return.
What counts as a reportable transaction?
Money and property moving between the LLC and its foreign owner, including your own contributions and distributions. Even funding the account and paying yourself back can be reportable, which is why many founders underestimate it.
