Form 5472 and the $25,000 Penalty: The Complete Guide for Foreign LLC Owners
- Every foreign-owned single-member US LLC must file a pro-forma Form 1120 with Form 5472 every year, even with no income or activity.
- Simply funding the company or paying its fees from your own pocket creates a "reportable transaction" that triggers the obligation.
- The deadline is April 15, extendable to October 15 with Form 7004.
- The penalty is $25,000 per form, per year, assessed automatically, and it compounds the longer the delay continues.
- E-filing is not available; both forms go together by mail or fax, and you keep proof of sending.
If you own a single-member US LLC and you are not a US resident, the IRS treats your company as a "disregarded entity." That status requires you to file a pro-forma Form 1120 with Form 5472 attached every year, even if the company earned nothing and had no activity at all. Filing late, incompletely, or not at all exposes you to a $25,000 penalty per form, per year, assessed automatically.
Who has to file this?
The rule applies to you if your US LLC has a single member, is 25% or more owned by a foreign person or entity, and had a "reportable transaction" during the year. Most Arab founders fall squarely inside this definition, because simply forming and funding the company already creates a reportable transaction. It does not matter whether the company is dormant, has no customers, or has no bank account yet.
What counts as a "reportable transaction"?
A reportable transaction is any movement of money between your company and you as its owner, or between the company and any party related to you. The threshold is so low that most owners cross it on day one without realizing. Common examples that create a filing obligation:
- Your initial funding of the company, even a small amount to open a bank account
- Paying formation fees or the state's annual fee out of your own pocket
- Moving money from you into the company, or from the company to you
- Loans between you and the company in either direction
- Withdrawing profits, or any payment the company makes to you as owner
The deadline: April 15, extendable to October 15
The pro-forma Form 1120 with Form 5472 is due April 15 for the prior tax year (so April 15, 2026 for the 2025 year). You can get an automatic six-month extension to October 15 by filing Form 7004 before the original deadline; it needs no approval or explanation from the IRS. But note: the extension postpones the filing date, it does not cancel the obligation.
Form 5472 is never sent on its own. It must be attached to a pro-forma Form 1120. Sending one without the other, or mailing them as two separate packages, is treated by the IRS as a complete failure to file and triggers the $25,000 penalty, even when both forms are filled out correctly.
How to file it correctly
- 1Get an Employer Identification Number (EIN) for the company if you don't have one; it is required on the form.
- 2Complete the pro-forma Form 1120: the company name and address, plus items B and E on page one, and write "Foreign-owned U.S. DE" across the top.
- 3Complete Form 5472 in full: the foreign owner's details, the related party, and the value of every reportable transaction during the year.
- 4Send both forms together by mail or fax to the IRS service center in Ogden, Utah. E-filing is not available for these two forms.
- 5Keep proof of sending (the mailing receipt or fax confirmation) as evidence that you met the deadline.
How the penalty compounds
The $25,000 is not a ceiling; it is the starting point. The IRS raised it from $10,000 to $25,000 under the Tax Cuts and Jobs Act of 2017 (TCJA), effective for tax years beginning after 2017. If the failure continues more than 90 days after the IRS sends notice, another $25,000 is added for every 30 days of delay, compounding quickly into large sums. This is why this obligation is one of the most costly things a foreign-owned US company owner can overlook.
Tip: If your numbers aren't ready before April 15, file Form 7004 for an extension to October 15. One minute of work now protects you from the $25,000 penalty and buys you six extra months.
How to stay compliant every year
Compliance here is not complex, but it is unforgiving, and the calendar is your first line of defense. Log every movement of money between you and the company throughout the year so no reportable transaction slips past you, and set an annual reminder in February to start preparing well before the April deadline. Filing on time keeps your company legally sound with the IRS year after year, and that alone is worth the care.

Frequently asked
My LLC earned no income this year. Do I still have to file Form 5472?+
Yes. The obligation is tied not to income but to whether a "reportable transaction" occurred, and simply funding the company or paying its fees counts as one. A fully dormant company with no money moving between you and it is the rare exception, and even then filing as a precaution is wise.
What is the penalty if I file late or forget?+
A minimum of $25,000 per form, per year, assessed automatically. And if the failure continues more than 90 days after the IRS sends notice, an additional $25,000 is added for every further 30 days.
Can I file the form electronically?+
No. The pro-forma Form 1120 and Form 5472 are not e-filed for this category; they go together by mail or fax to the IRS service center in Ogden, Utah. Keep the mailing receipt or fax confirmation as proof you met the deadline.
When is the deadline and how do I get an extension?+
April 15 for the prior tax year. For an automatic extension to October 15, file Form 7004 before April 15; it needs no approval or explanation from the IRS.
Do I need an EIN to file the form?+
Yes, an Employer Identification Number (EIN) is required on the form. If you don't have one, get it before the filing deadline.
