Form 5472: Filing Guide for Foreign-Owned US LLCs

Form 5472 is the IRS information return that a foreign-owned single-member US LLC must file every year to report transactions with its foreign owner. Even if your LLC owes zero US tax, you attach Form 5472 to a pro forma Form 1120. Skipping it triggers a minimum penalty of $25,000.

This guide is written for founders who formed a US LLC without an SSN or a US address. It sequences the whole compliance chain — from getting an EIN, to spotting reportable transactions, to filing on time — so a non-resident owner can meet the requirement without a US CPA on speed dial. Last updated: July 2026.

What Is Form 5472? (The Foreign-Owned LLC Reporting Rule)

Form 5472 is titled "Information Return of a 25% Foreign-Owned US Corporation or a Foreign Corporation Engaged in a US Trade or Business." Since 2017, the IRS has treated a foreign-owned single-member LLC (a "disregarded entity") as if it were a corporation for this reporting purpose only. That means your simple one-owner LLC inherits a corporate-style filing duty, even though it is not taxed as a corporation.

The form itself does not calculate any tax. It is an information return: it tells the IRS who owns the entity, where they live, and what money moved between the owner and the LLC during the year. The authority comes from Internal Revenue Code Sections 6038A and 6038C. Always confirm the current version and instructions on IRS.gov before filing, as the form is updated most years.

Why a Simple LLC Suddenly Has a Corporate Filing

A US-owned single-member LLC is normally invisible to the IRS — the owner just reports income on a personal return. When the owner is foreign and has no US filing obligation of their own, the IRS lost visibility into these entities. The 2017 regulations closed that gap by forcing the LLC to file Form 5472 with a pro forma (skeleton) Form 1120 so the government can see the money flows.

Who Must File Form 5472?

You must file if your US LLC is a reporting corporation for the year, which includes a foreign-owned disregarded entity. In plain terms, you file Form 5472 if all of the following are true:

• Your business is a US LLC (formed in Wyoming, Delaware, or any state).
• It is a single-member LLC treated as a disregarded entity (you did not elect corporate taxation).
• At least 25% of the LLC is owned by a foreign person — a non-resident individual, a foreign company, or a foreign trust. For most of our clients, that means 100% foreign-owned.
• The LLC had at least one reportable transaction with the foreign owner or a related party during the tax year.

Two points catch people out. First, a dormant LLC still files if it had reportable transactions — and simply contributing your startup capital or paying formation costs usually counts as one. Second, this is separate from any income-tax question. Whether or not a non-resident LLC actually owes US tax, the 5472 information return is generally still due.

Who Does Not File

A US-owned single-member LLC does not file Form 5472. A multi-member LLC taxed as a partnership files Form 1065 instead (with different foreign-owner reporting). And an LLC that elected to be taxed as a corporation follows normal 1120 rules. If you are unsure which bucket you fall into, confirm your entity classification before the deadline.

What Counts as a Reportable Transaction

A reportable transaction is almost any exchange of money or value between your LLC and you (its foreign owner) or a related foreign party. For a disregarded entity, the definition is broad and includes contributions and distributions — not just sales. The table below shows realistic scenarios for a non-resident founder.

Scenario	Reportable?	Notes
You wire startup capital into the LLC's bank account	Yes	A contribution from owner to entity is reportable.
You pay the state filing fee or registered-agent fee personally on the LLC's behalf	Yes	Amounts paid by the owner for the entity count.
You take money out of the LLC to your personal account	Yes	A distribution from entity to owner is reportable.
The LLC pays you a management or service fee	Yes	Payments between owner and entity are reportable.
The LLC lends money to your other foreign company	Yes	Related-party loans and the balances are reportable.
The LLC only sells to unrelated US customers and never touches your accounts	Often No	Sales to unrelated third parties are generally not 5472 transactions — but capital in/out usually still triggers filing.

Because funding the company and paying its startup costs almost always create a reportable transaction, most newly formed foreign-owned LLCs must file Form 5472 for their very first year. Treat filing as the default, not the exception.

Form 5472 and Your EIN: Why You Need One First

You cannot file Form 5472 or the attached Form 1120 without an Employer Identification Number (EIN). The EIN is the entity's tax ID, and both forms require it at the top. This is why the compliance chain starts the day you form the company — not in April.

As a non-resident with no Social Security Number, you get your EIN by filing IRS Form SS-4, writing "Foreign" on line 7b where an SSN or ITIN would go. You submit it by fax or mail, because the IRS online EIN tool requires an SSN or ITIN. Our full walkthrough on how to get an EIN without an SSN covers the exact method; expect a few business days by fax to the IRS international line at +1 (304) 707-9471, or roughly 4–6 weeks by mail.

If a bank later asks you to re-verify the EIN, or you lose your original confirmation, you request a 147C letter from the IRS Business & Specialty Tax Line at 1-800-829-4933. Keep both the EIN confirmation and any 147C with your tax records — you will reference the EIN on every future 5472.

How to Complete Form 5472: Step-by-Step

Form 5472 is short, but the parts that apply to a foreign-owned single-member LLC are specific. Work through it in this order.

1. Part I — Reporting Corporation. Enter the LLC's legal name, US address (your registered-agent address is fine), EIN, country of incorporation (United States), and the principal business activity. Check the box indicating the entity is a foreign-owned US disregarded entity.
2. Part II — 25% Foreign Shareholder. Enter your details as the foreign owner: full legal name, your foreign address, and the country under whose laws you file (or where you are a citizen/resident). Because you have no US taxpayer ID, follow the current instructions on how to complete the identifying-number field.
3. Part III — Related Party. Identify the related party to the transactions — for a solo founder, this is usually you again as the owner.
4. Parts IV, V, and VI — Transactions. Report the monetary and non-monetary transactions between the LLC and the foreign related party. For most disregarded entities, the amounts contributed to and distributed from the LLC are reported here (the instructions direct disregarded entities to Part V/VI for these). Enter totals in US dollars.

Fill in only the parts that apply, and enter "0" or leave lines blank per the instructions where there is nothing to report. Always cross-check line references against the current-year Instructions for Form 5472 on IRS.gov, since part numbering and boxes shift between revisions.

Filing With a Pro Forma Form 1120

A disregarded entity does not file Form 5472 by itself. You attach it to a pro forma Form 1120 — a stripped-down US corporate return used purely as a cover page. "Pro forma" means you do not complete the income and tax sections the way a real corporation would.

In practice you: write the LLC's name, address, and EIN at the top of Form 1120; write "Foreign-owned US DE" across the top of the form (as the instructions direct); leave the income, deduction, and tax lines blank; and attach Form 5472 behind it. The 1120 here carries no tax — it exists only so the 5472 has a return to ride on. This package is separate from any personal effectively connected income filing you might have; if you sell into the US, review whether you also owe income tax before you assume $0.

Deadline and How to File Form 5472

The Form 5472 package follows the Form 1120 calendar. For a calendar-year LLC, the deadline is generally April 15. You can request an automatic extension with Form 7004 to push the due date to October 15. Confirm the exact 2026 dates on IRS.gov, as deadlines shift when the 15th falls on a weekend or holiday.

Because a foreign-owned disregarded entity cannot e-file the pro forma 1120 through the normal channels, you file by fax or mail to the special address and fax number listed in the current Form 5472 instructions (a dedicated Ogden, Utah service center handles these). Keep your fax confirmation or mail receipt — it is your proof of timely filing.

Item	Detail (as of 2026 — verify current)
Standard deadline	April 15 (calendar-year LLC)
Extended deadline	October 15 (file Form 7004 by April 15)
What you file	Form 5472 attached to a pro forma Form 1120
How you file	Fax or mail to the IRS service center in the instructions (no standard e-file)
Keep as proof	Fax confirmation sheet or certified-mail receipt

Penalties for Not Filing Form 5472

This is the part non-residents underestimate. Under IRC Section 6038A, the penalty for a late, incomplete, or missing Form 5472 is a minimum of $25,000 per form, per year. It applies even when your LLC made no profit and owed no tax. If you fail to fix the problem after the IRS notifies you, additional $25,000 penalties can accrue.

Situation	Consequence
File late or with missing information	Minimum $25,000 penalty (IRC 6038A)
Continued failure after IRS notice	Additional $25,000 for each 30-day period of continued non-compliance
Never file for multiple years	Penalties can stack per year — potentially six figures
Filed late but with reasonable cause	Penalty may be abated if you show a valid reason (see below)

Reasonable-Cause Relief

If you missed a year, do not ignore it. The IRS can waive the penalty for reasonable cause — a genuine, documented reason you could not file on time, filed as soon as you realized, and acted in good faith. You attach a signed reasonable-cause statement to the late filing. Because the stakes are high, this is one situation where paying a US tax professional to prepare the delinquent package and statement is usually worth it.

Common Mistakes Non-Resident Owners Make

• Assuming "no profit" means "no filing." Form 5472 is an information return; a $0 tax year with capital contributions still requires it.
• Forgetting that funding the company is a reportable transaction. Your first wire into the business bank account usually triggers the first-year filing.
• Filing the 5472 without the pro forma 1120. The 5472 must be attached to the 1120 cover; alone, it is not a valid filing.
• Trying to e-file. Foreign-owned disregarded entities generally file by fax or mail to the special service center.
• Missing the EIN step. No EIN means no valid return — start the SS-4 the week you form.
• Losing filing proof. Keep the fax confirmation; it is your defense against a wrongly assessed penalty.

The cleanest way to avoid every one of these is to set the LLC up correctly from day one — correct entity type, EIN in hand, and a clean record of owner-to-entity transactions.

Frequently Asked Questions

Do I need to file Form 5472 if my LLC made no money?

Usually yes. Form 5472 reports transactions, not profit. If you contributed startup capital, paid the LLC's costs personally, or took any money out, you had a reportable transaction and must file with a pro forma Form 1120 — even with $0 income and $0 US tax owed.

What is the penalty for not filing Form 5472?

The minimum penalty under IRC Section 6038A is $25,000 per form, per year, for a late, incomplete, or missing Form 5472. It applies regardless of profit. Continued failure after the IRS notifies you can add further $25,000 penalties, so filing on time is critical.

Can I file Form 5472 without an EIN?

No. Both Form 5472 and the pro forma Form 1120 require your LLC's EIN. Non-residents get one by filing Form SS-4 with "Foreign" on line 7b, submitted by fax or mail. Start the EIN process right after formation so you are ready before the deadline.

When is Form 5472 due?

For a calendar-year LLC, the package is generally due April 15, the same as Form 1120. You can extend to October 15 by filing Form 7004 on time. Confirm the exact 2026 dates on IRS.gov, since deadlines move when the 15th lands on a weekend or holiday.

How do I actually submit Form 5472?

Attach Form 5472 to a pro forma Form 1120 and send it by fax or mail to the special IRS service center listed in the current instructions. Foreign-owned disregarded entities generally cannot e-file this package. Keep your fax confirmation or certified-mail receipt as proof of timely filing.

Does opening a US bank account change my Form 5472 duty?

The account itself does not, but the money moving through it often does. Wiring capital in or taking distributions out are reportable transactions. Before you apply, read our guide to opening a US business bank account for non-residents so your records are clean from the first deposit.

Can a penalty be removed if I filed late?

Possibly. The IRS may abate the penalty for reasonable cause if you show a genuine, documented reason for filing late, filed as soon as you could, and acted in good faith. Attach a signed reasonable-cause statement to the delinquent return, and consider hiring a CPA given the amounts involved.
