What is Form 5472?

Form 5472 is officially titled "Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business." Despite the title referring to "corporations," it applies to all foreign-owned single-member LLCs that are treated as disregarded entities for US tax purposes.

The IRS uses Form 5472 to track transactions between US entities and their foreign owners. It is an information return — not a tax return. You are not paying tax through this form. You are reporting the existence and nature of transactions between your LLC and you (the foreign owner).

The legal basis is IRC Section 6038A, which was extended to disregarded entities owned by foreign persons by Treasury Regulations finalized in December 2016 (TD 9796). Before 2017, foreign-owned single-member LLCs had virtually no IRS reporting obligations. That changed.

Who must file Form 5472

You must file Form 5472 if all three of the following are true:

1. You own a US LLC (or other disregarded entity)
2. You are a non-US person (foreign individual, foreign corporation, or foreign partnership)
3. The LLC had at least one "reportable transaction" during the tax year

The critical point: the definition of "reportable transaction" is extremely broad. The initial capital contribution to your LLC counts. If you deposited $100 into your LLC bank account, that is a reportable transaction. If you paid for your LLC's domain name from your personal credit card, that is a reportable transaction.

In practice, every foreign-owned LLC must file Form 5472. There is no realistic scenario where a functioning LLC has zero reportable transactions.

The $25,000 penalty

The penalty for failing to file Form 5472 (or filing it incorrectly or incompletely) is $25,000 per form, per year. This is an automatic penalty — the IRS does not need to prove intent or negligence.

How penalties escalate

If the IRS notifies you of the failure to file and you do not respond within 30 days:

• Initial penalty: $25,000
• After 30 days of non-response: additional $25,000
• After 60 days: another $25,000
• And so on: $25,000 for each additional 30-day period

There is no maximum cap on these continuation penalties. A single unfiled form can theoretically generate penalties of $100,000 or more if ignored for several months.

Multiple years compound

If you have not filed for three years, you owe the penalty for each year separately. Three years of non-filing means a minimum of $75,000 in penalties before any continuation penalties are added.

Penalty abatement

The IRS may reduce or eliminate Form 5472 penalties through "reasonable cause" abatement, but this requires demonstrating that you had a legitimate reason for not filing (not simply that you did not know about the requirement). The success rate for penalty abatement varies, and professional representation is strongly recommended. USLLCGlobal is not a law firm and cannot represent you before the IRS for penalty matters — consult a tax attorney if you have unfiled returns.

You cannot e-file Form 5472

This catches many LLC owners off guard. As of 2026, Form 5472 cannot be electronically filed. It must be submitted as a paper filing.

How to submit

By mail:

Department of the Treasury
Internal Revenue Service
Ogden, UT 84201-0038

By fax: The IRS provides a fax number in the Form 5472 instructions. Check the current IRS instructions for the most up-to-date fax number, as it changes periodically.

We recommend mailing via USPS Certified Mail with Return Receipt to create a paper trail proving the filing was submitted. The IRS does not send filing confirmations for Form 5472, so your mailing receipt is the only proof of timely filing.

What information is reported

Form 5472 has four main parts:

Part I: Reporting corporation

Your LLC's name, EIN, address, date of incorporation, state of incorporation, and principal business activity. Even though your LLC is technically a "disregarded entity," it reports as the "reporting corporation" on Form 5472.

Part II: 25% foreign shareholder

Your personal information as the foreign owner: name, address, country of citizenship, country of residence, and taxpayer identification number (if you have one). If you are the sole owner, you are a "25% foreign shareholder" (in fact, a 100% foreign shareholder).

Part III: Related party information

Details about any other related parties who had transactions with your LLC. For most single-member LLCs, Part II and Part III refer to the same person (you).

Parts IV-VI: Reportable transactions

The dollar amounts of transactions between your LLC and the foreign owner/related parties. This includes:

• Capital contributions — money you deposited into the LLC
• Loans — money lent between you and the LLC
• Payments for services — if the LLC paid you for consulting, management, etc.
• Rent — if the LLC rents property from you or vice versa
• Purchases/sales of tangible property
• Interest, royalties, licence fees
• Other amounts — any transfer of value between you and the LLC

The form asks for aggregate dollar amounts by category. You do not need to itemise every individual transaction — just the total for each category during the tax year.

The pro-forma Form 1120

Form 5472 is not filed alone. It must be filed with a pro-forma Form 1120 (U.S. Corporation Income Tax Return). This sounds intimidating, but the pro-forma 1120 is essentially a cover page.

For a foreign-owned disregarded entity (your single-member LLC), the pro-forma Form 1120 is completed as follows:

• Enter the LLC name, EIN, and address
• Check the box for "initial return" (first year only)
• Write "Foreign-Owned U.S. DE" across the top of the form
• Enter zeros for all income, deductions, and tax line items
• Attach Form 5472
• Sign and date

The pro-forma 1120 does not result in any tax liability. Its sole purpose is to serve as the filing vehicle for Form 5472.

Deadline and extensions

Standard deadline

Form 5472 with pro-forma 1120 is due April 15 following the end of the LLC's tax year. For LLCs using the calendar year (January 1 - December 31), the 2025 filing is due April 15, 2026.

Extension

You can request an automatic 6-month extension to October 15 by filing Form 7004 (Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns) before the April 15 deadline. Form 7004 can be e-filed.

Important: the extension extends the filing deadline, not the penalty clock. If the IRS determines you were required to file and did not, the penalty accrues from April 15 regardless of whether an extension was filed.

First-year timing

If your LLC was formed mid-year (for example, July 2025), your first Form 5472 covers the short tax year from the formation date through December 31, 2025, and is due April 15, 2026.

Common mistakes

1. Assuming zero income means no filing requirement

The most common mistake. Your LLC had no revenue? You still must file if there were any reportable transactions — and the initial capital contribution counts. File every year, regardless of income.

2. Forgetting the pro-forma 1120

Sending Form 5472 alone, without the pro-forma 1120, results in the IRS rejecting the filing. Both forms must be submitted together, in the same envelope.

3. Not writing "Foreign-Owned U.S. DE" on the 1120

Without this notation, the IRS may process your pro-forma 1120 as a regular corporate return, generating automated notices requesting missing schedules and financial data.

4. Trying to e-file

Form 5472 must be paper-filed. Attempting to e-file results in rejection. Print, sign, and mail to Ogden, UT.

5. Missing the April 15 deadline without filing an extension

Filing even one day late without an extension on file triggers the $25,000 penalty. File Form 7004 by April 15 if you need more time.

6. Using the LLC's registered agent address as the owner's address

Part II of Form 5472 asks for the foreign owner's address. This must be your personal foreign address, not the LLC's US registered agent address. Using the US address creates inconsistencies that may trigger IRS scrutiny.

7. Not keeping records of what you filed

The IRS does not send an acknowledgment letter for Form 5472 filings. Send via USPS Certified Mail and keep the receipt for at least six years. This is your only proof of timely filing if the IRS claims you did not file.
