Foreign owners of US entities often discover Form 5472 after the deadline, when the minimum penalty is already $25,000 per form. Form 5472 is the Internal Revenue Service (IRS) information return that reports transactions between a US company and its foreign related parties. This guide covers US tax compliance for foreign owners of limited liability companies (LLCs), foreign-owned C-Corporations (C-Corps), and foreign corporations doing business in the US.
Form 5472 is one of the most misunderstood requirements in cross-border tax compliance for foreign-owned US entities. Filing it does not mean you owe tax. Failing to file triggers the penalty even when you owe nothing. Start with the official IRS About Form 5472 page, then use the summary below.

What Is IRS Form 5472?
Form 5472 is the Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business, per the IRS. It is an information return, not a tax return. It reports related-party transactions and computes no tax by itself. Filing it does not mean tax is owed.
Corporations file Form 5472 to satisfy Internal Revenue Code (IRC) sections 6038A and 6038C, according to the IRS Instructions for Form 5472 (Rev. December 2024). Section 6038A covers 25% foreign-owned domestic corporations. Section 6038C covers foreign corporations engaged in a US trade or business. These statutes create both the recordkeeping duty and the penalty. In plain terms, the form tells the IRS who owns the US business, what transactions occurred between related parties, and whether pricing is arm’s length. Failing to file triggers penalties regardless of tax owed.
Who Needs to File Form 5472?
Three filers must file Form 5472: a US corporation at least 25% foreign-owned, a foreign-owned US disregarded entity (DE) such as a single-member LLC, and a foreign corporation engaged in a US trade or business. The 25% threshold is tested by vote or value, per the IRS Instructions for Form 5472.
Ownership counts directly and indirectly. The §318 attribution rules apply, so you cannot split ownership among related foreign persons to duck the 25% threshold. A “foreign person” is a non-resident alien, foreign entity, or foreign government. A US citizen living abroad is not a foreign person. A “related party” includes any 25% foreign shareholder plus persons related under IRC §267(b), §707(b)(1), or §482, per 26 U.S.C. §6038A.
Which US corporations count as 25% foreign-owned?
A US corporation is 25% foreign-owned when one foreign person owns at least 25% of the total voting power or total value of its stock at any time in the year, per IRC §6038A. A 25% foreign-owned corporation with no reportable transactions during the year generally does not file.
What makes a foreign-owned disregarded entity a filer?
A foreign-owned US disregarded entity, most often a single-member LLC owned by a non-US person, files if it had any reportable transaction at all. This is the asymmetry trap: a corporation can skip filing with no transactions, but a DE cannot. The DE is treated as a domestic corporation solely for Form 5472 reporting.
When must a foreign corporation in a US trade or business file?
A foreign corporation engaged in a US trade or business files Form 5472 for any reportable transaction with a related party during the year, under IRC §6038C. The IRS names this filer directly in the form’s official title. The same $25,000 penalty and recordkeeping rules apply to it.
What Are Reportable Transactions on Form 5472?
A reportable transaction is any monetary or non-monetary exchange with a related party: sales, loans, management and service fees, royalties, rent, and capital contributions, per the IRS Instructions for Form 5472. Income is irrelevant. The trigger is the transaction, not profit. A nil tax return does not remove the obligation.
For disregarded entities the definition is broader. Under T.D. 9796 and 26 CFR §1.6038A-2(b)(3)(xi), reportable transactions include amounts paid or received in connection with the formation, dissolution, acquisition, and disposition of the entity, plus contributions and distributions between the owner and the LLC. So funding your own LLC from a foreign personal account is reportable. Everyday examples: a foreign parent injects capital into its US subsidiary, a US LLC pays management fees to its foreign owner, a US company buys inventory from an overseas affiliate, and a foreign shareholder lends money to a US entity. Each is a reportable transaction.
How Does Form 5472 Work for a Foreign-Owned Single-Member LLC?
A foreign-owned single-member LLC files Form 5472 attached to a pro forma Form 1120 every year, even with zero income and zero tax due. Only the header of the Form 1120 is completed: name, address, Employer Identification Number (EIN), and the applicable checkbox. The attached Form 5472 carries the transaction detail.
The requirement is recent, which is why owners are blindsided. Under T.D. 9796, effective for tax years beginning after December 31, 2016, the IRS treats foreign-owned LLCs and other disregarded entities as domestic corporations solely for Form 5472 reporting. Before that, many had no federal filing requirement at all. Two practical blockers matter. The LLC must have an EIN. A foreign owner can obtain an EIN without a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). The pro forma Form 1120 with Form 5472 is filed by mail or fax to the address in the current IRS instructions, not through standard corporate e-file.
When Is Form 5472 Due?
Form 5472 is due with the reporting corporation’s income tax return, including extensions, per the IRS Instructions for Form 5472. For calendar-year filers that is generally April 15. Deadlines shift with fiscal year and entity type. A six-month extension is available through Form 7004.
| Filer and return | Standard due date | Extension | Extended due date | Source |
|---|---|---|---|---|
| Foreign-owned SMLLC (pro forma Form 1120) | April 15 (calendar year) | Form 7004 | October 15 | IRS Instructions for Form 5472 |
| Calendar-year C-Corp (Form 1120) | April 15 | Form 7004 | October 15 | IRS Instructions for Form 5472 |
| Fiscal-year corporation | 15th day of 4th month after year-end | Form 7004 | Plus 6 months | IRS Instructions for Form 5472 |
| Foreign corporation (Form 1120-F) | 15th day of 4th month (US office) or 6th month (no US office) | Form 7004 | Plus 6 months | IRS Instructions for Form 5472 |
First-year filing catches new owners. The obligation starts with the first tax year that contains a reportable transaction. For a new LLC that is usually the formation year, because the initial capital contribution is itself reportable.
How Do You File Form 5472?
Attach Form 5472 to Form 1120, to the pro forma Form 1120 for a disregarded entity, or to Form 1120-F for a foreign corporation. File by the return’s method: e-file where the return is e-filed, or mail or fax the DE pro forma package per the IRS instructions. File one Form 5472 for each foreign related party with reportable transactions.
The current form (Rev. December 2024) has nine parts, per the IRS Instructions for Form 5472.
| Part | What it reports | Source |
|---|---|---|
| Part I | Reporting corporation information | IRS Instructions for Form 5472 |
| Part II | 25% foreign shareholder | IRS Instructions for Form 5472 |
| Part III | Related party | IRS Instructions for Form 5472 |
| Part IV | Monetary transactions with the foreign related party | IRS Instructions for Form 5472 |
| Part V | Reportable transactions of a foreign-owned US DE | IRS Instructions for Form 5472 |
| Part VI | Nonmonetary and less-than-full-consideration transactions | IRS Instructions for Form 5472 |
| Part VII | Additional information | IRS Instructions for Form 5472 |
| Part VIII | Cost Sharing Arrangement (CSA) | IRS Instructions for Form 5472 |
| Part IX | Base erosion payments under Section 59A | IRS Instructions for Form 5472 |
Part IX covers the Base Erosion and Anti-Abuse Tax (BEAT), which applies mainly to large corporations, not to the typical single-member LLC.
What Are the Penalties for Not Filing Form 5472?
The penalty is $25,000 per form, per year, for failing to file, filing late, or filing a substantially incomplete form, per the IRS Instructions for Form 5472. It applies even when no tax is owed. A substantially incomplete Form 5472 is treated as a failure to file. The same $25,000 penalty applies to recordkeeping failures under IRC §6038A.
| Trigger | Penalty | Source |
|---|---|---|
| Failure to file | $25,000 per form, per year | IRS Instructions for Form 5472 |
| Late filing | $25,000 per form, per year | IRS Instructions for Form 5472 |
| Substantially incomplete filing | $25,000 per form, per year | IRS Instructions for Form 5472 |
| Recordkeeping failure under §6038A | $25,000 per taxable year | IRC §6038A(d) |
| Failure continues after IRS notice | Additional $25,000 per 30-day period, uncapped | IRS Instructions for Form 5472 |
The penalty is not capped. If the failure continues more than 90 days after the IRS mails notice, an additional $25,000 applies for each 30-day period, or part of one, until it is corrected, per 26 U.S.C. §6038A. The Tax Cuts and Jobs Act of 2017 (TCJA) raised the penalty from $10,000 to $25,000 for tax years beginning after December 31, 2017, per Public Law 115-97. Each form carries its own exposure, so a company with several foreign related parties multiplies the risk.
Can You Get a Form 5472 Penalty Waived?
Yes. The IRS can abate the Form 5472 penalty for reasonable cause, but there is no automatic first-time relief for this form, and “I didn’t know” alone rarely qualifies. Reasonable cause means facts showing ordinary business care and prudence, per the IRS reasonable cause guidance.
The IRS often auto-assesses the $25,000 penalty on late pro forma filings from foreign LLC owners. The practical path for a late filer is to file the delinquent Form 5472 with a written reasonable cause statement attached, rather than waiting for a notice. If a notice already arrived, respond in writing with the facts, dates, and steps taken to fix the failure. Documented, prompt correction is the strongest position for abatement.
Form 5472 vs Form 5471: What Is the Difference?
Form 5472 reports foreign ownership into the US: foreign persons owning US entities. Form 5471 reports US ownership of foreign corporations: US persons who are officers, directors, or shareholders of a foreign corporation. They are mirror images. Some cross-border groups file both.
| Form 5472 | Form 5471 | |
|---|---|---|
| Direction | Inbound: foreign ownership of a US entity | Outbound: US ownership of a foreign corporation |
| Who files | 25% foreign-owned US corp, foreign-owned US DE, foreign corp in US trade or business | US officers, directors, shareholders of a controlled foreign corporation (CFC) |
| Governing statute | IRC §6038A / §6038C | IRC §6038 / §6046 |
| What it reports | Related-party transactions | Foreign corp income, earnings, ownership, transactions |
| Base penalty | $25,000 per form, per year | $10,000 per form, per year |

If a foreign person owns your US company, you likely need Form 5472. If you own a foreign company from the US, you likely need Form 5471.
What Are the Form 5472 Recordkeeping Requirements?
Section 6038A imposes a standing recordkeeping duty separate from the filing itself. A reporting corporation must keep records sufficient to establish the accuracy of the return and the correct US tax treatment of related-party transactions, per IRC §6038A. Recordkeeping failures carry the same $25,000 penalty as a failure to file.
Maintain four categories of documentation: transaction records, intercompany agreements, transfer pricing documentation supporting arm’s length pricing under IRC §482, and financial statements. Management fees, royalties, and intercompany loan interest are the classic §482 scrutiny points. The IRS requests these records in audit to test whether related-party pricing matches what unrelated parties would charge. Keeping them contemporaneous is what turns a Form 5472 filing into a defendable one.
