Avoid the $25K Penalty with Form 5472 for Foreign-Owned LLCs

Why a single-member foreign-owned LLC still has a federal filing duty
As an Enrolled Agent, I often meet non-US founders who assume their single-member LLC has no federal filing because they have no Social Security Number or ITIN and the company owes no US tax. That assumption is expensive. Since 2017 the IRS treats a US LLC with one foreign owner as a corporation for one purpose only: information reporting under Internal Revenue Code section 6038A. In any year the LLC has a reportable transaction with its foreign owner, it must file Form 5472 attached to a pro forma Form 1120, even when the income tax due is zero.
For example, take a designer in Mexico who forms a Wyoming LLC to invoice US clients. He does the work from Mexico, owes no US income tax, and moves money between his personal account and the LLC all year. Each of those transfers is a reportable transaction, so the filing is due even though no tax is.
The pro-forma 1120 + Form 5472 requirement explained
The pro forma Form 1120 is a cover sheet. You fill in the LLC's name, address and EIN, write "Foreign-owned U.S. DE" across the top, and attach Form 5472. Form 5472 identifies the foreign owner and lists the transactions between the owner and the LLC during the year. The package is due on the corporate deadline, April 15 for a calendar-year LLC, and Form 7004 filed by that date extends it to October 15. It cannot be e-filed through the normal channels: it goes to the IRS by fax, or by mail to Ogden, Utah.
For instance, a founder in Brazil who opens an LLC to collect payments through PayPal or Stripe, funds the account with her own money and later pays herself, files both forms for every year she has that kind of activity. The filing reports the transactions between her and her LLC, not her sales to customers.
What "reportable transactions" actually means
A reportable transaction is a transaction between the LLC and its foreign owner or another related party. For a foreign-owned disregarded LLC the definition is broad and has no minimum dollar amount. Capital contributions (including the first deposit that opens the bank account), distributions to the owner, loans in either direction, and expenses the owner pays personally on the LLC's behalf, such as the formation fee or the registered agent, all count.
Payments from unrelated customers are not reportable transactions by themselves. If a founder in Canada receives $30,000 from a US client for web development, that sale does not go on Form 5472. When she moves the money from the LLC to her personal account, that distribution does. In practice almost every active LLC has at least one reportable transaction each year. See the form part by part.
The automatic penalty if you miss the deadline
The penalty for not filing Form 5472, filing it late, or filing it substantially incomplete is $25,000 per form under section 6038A(d). It applies even when the LLC owes no US tax, and it applies for each year missed. If the IRS sends a notice and the failure continues more than 90 days after it, another $25,000 is added for each further 30-day period. The only way to move the deadline is Form 7004, and it must be filed on or before the original due date.
For instance, if a founder in Germany remembers the form five months after April 15 and never filed Form 7004, the return is late and the $25,000 penalty can be assessed. An extension request sent after the due date does not cure a late filing.
Late-filing relief options
If you missed the deadline, file the pro forma Form 1120 and Form 5472 as soon as possible. Do not wait for an IRS notice. The penalty can be waived when the failure was due to reasonable cause and not willful neglect, so a late filing should go in with a signed statement of the facts: what happened, when you learned of the requirement, and what you did to correct it. First-time penalty abatement generally does not apply to this penalty, so the reasonable-cause statement carries the weight.
For example, a founder in France who files every missing year as soon as she learns of the requirement, with a clear written explanation, is in a stronger position than one who ignores IRS letters. Relief is decided case by case and is never automatic. If several years are missing, have an Enrolled Agent or other licensed professional prepare the filings and the statement together.
Building this into your annual compliance calendar
To stay out of this, put the filing on your annual calendar: April 15 for the pro forma Form 1120 and Form 5472, or Form 7004 by April 15 if you need until October 15. Keep a simple ledger of every transfer between you and the LLC during the year, because those are the numbers the form asks for.
If you are forming an LLC now, the first Form 5472 will usually be due the following April, since funding the company is itself a reportable transaction. Set the reminder on the day the LLC is formed.

Common Questions
Is the Form 5472 penalty $25,000 or $10,000?
It is $25,000. The penalty was $10,000 until the 2017 tax law raised it to $25,000 for tax years beginning after December 31, 2017. It applies per reporting corporation for each year a required Form 5472 is not filed on time or is substantially incomplete. If the failure continues more than 90 days after the IRS sends notice, another $25,000 can apply for each 30-day period.
Does the penalty apply if my LLC had no income?
It can. The filing duty comes from reportable transactions with the owner, such as money you put into the LLC or take out of it, not from income. An LLC with no sales can still owe a Form 5472.
