IRS Form 5472: Filing requirements, instructions, and penalties

IRS Form 5472 is required when a reporting corporation has a reportable transaction with a related party. For the 2025 calendar year, the filing is generally due April 15, 2026, and an incomplete or late form can trigger a $25,000 penalty.

The rule covers a 25% foreign-owned US corporation, a foreign corporation engaged in a US trade or business, and a foreign-owned US disregarded entity when the filing conditions apply. It does not apply to every foreign-owned business structure.

For broader entity reporting, see our foreign company tax reporting guide. The Form 5472 penalty guide covers the $25,000 initial penalty and relief factors in more detail.

As of August, 2026, the IRS lists no newer dedicated revision than the December 2024 IRS instructions for Form 5472. The 2025 return rules and current Form 7004 instructions still control 2026 filing dates.

The following 4 items give the 2026 filing picture at a glance:

• Filer type: A reporting corporation, including a qualifying foreign-owned US disregarded entity.
• Trigger: A reportable transaction with a related party during the tax year.
• Due date: April 15, 2026, for a 2025 calendar-year Form 1120 filer, subject to a valid extension.
• Penalty: $25,000 for a required Form 5472 that is late or substantially incomplete.

What is IRS Form 5472?

IRS Form 5472 is an information return used by specific reporting corporations to disclose reportable transactions with related parties. For 2025 activity filed in 2026, the core threshold for a domestic corporation is at least 25% direct or indirect foreign ownership.

The Form 5472 purpose is disclosure, not calculation of a separate federal income tax. It helps the IRS identify transactions involving a foreign owner, another related person, or a foreign corporation engaged in a US trade or business.

Form 5472 explained: Tax Form 5472 reports specified related-party transactions. A 5472 tax form filing may be required even when the entity has little or no taxable income.

The following 4 common situations can bring the US Form 5472 rules into play:

• A US corporation is at least 25% foreign-owned and has a reportable transaction.
• A foreign corporation engaged in a US trade or business has a reportable transaction.
• A foreign-owned US single-member LLC receives a capital contribution from its owner.
• A reporting corporation makes a loan, service payment, rent payment, or property transfer involving a related party.

Form 5472 is different from FBAR and FATCA reporting. See how FBAR differs from FATCA when foreign accounts or specified foreign financial assets also exist.

A US-owned foreign disregarded entity follows a different reporting path. Our updated Form 8858 guide for foreign disregarded entities explains that distinction.

The federal Form 5472 filing rules come from sections 6038A and 6038C. In IRS guidance for Form 5472, a “reporting corporation” has a defined scope rather than meaning every business with a foreign connection.

Do I need to file Form 5472?

You may need Form 5472 for 2025 if your entity falls into 1 of 3 filer groups and had a reportable transaction with a related party. A foreign-owned US disregarded entity has special rules, including owner contributions and distributions that can count as reportable transactions.

Use the following 3-step decision sequence before preparing the form:

1. Is the entity a 25% foreign-owned US corporation? If yes, move to the reportable-transaction test.
2. Is it a foreign corporation engaged in a US trade or business? If yes, test related-party transactions.
3. Is it a US disregarded entity wholly owned by a foreign person? If yes, check Parts IV, V, and VI transaction rules.

If none of those 3 descriptions fits, Form 5472 usually is not the form that creates the filing duty. Entity classification still matters, especially for a US LLC formed by a nonresident.

Tax residence and immigration labels do not by themselves decide the entity filing. Review the distinction between resident and nonresident alien tax rules when the owner also has an individual US filing question.

If you answer yes to any of the 3 entity tests, check whether a reportable transaction occurred. A yes on both the entity-status test and transaction test means Form 5472 may apply.

Who must file Form 5472?

Who must file Form 5472 depends on both entity status and reportable transactions. For 2025, the main groups are 25% foreign-owned US corporations, foreign corporations engaged in a US trade or business, and foreign-owned US disregarded entities treated specially under section 6038A.

The following 3 filer categories cover the main cases:

• 25% foreign-owned US corporation: A foreign person directly or indirectly owns at least 25% of the vote or value, and a reportable transaction occurs.
• Foreign corporation with a US trade or business: The corporation has a reportable transaction with a related party.
• Foreign-owned US disregarded entity: A US DE wholly owned by a foreign person has a Part IV, V, or VI reportable transaction.

The key rule is that ownership or status alone is not enough – a reportable transaction is also required under the Form 5472 filing rules.

 

So, who needs to file Form 5472? The following 4 checks give a fast answer:

• Does the entity fit 1 of the 3 reporting-corporation categories above?
• Did it have at least 1 reportable transaction during 2025?
• Was that transaction with a related party, or a Part V transaction for a foreign-owned US DE?
• Does an IRS filing exception apply to the facts?

Do not use a universal 10% rule here. That figure belongs to parts of the separate Form 5471 filing system, not the 25% ownership threshold used for a domestic Form 5472 reporting corporation.

What is a related party?

A Form 5472 related party is defined by ownership and tax-law relationship rules, not by whether two businesses share a name. For 2025, the definition can include a 25% foreign shareholder and persons related under sections 267(b), 707(b)(1), or 482.

The following 3 relationship types are the main checks:

• Direct ownership: A person directly holds at least 25% of the reporting corporation.
• Indirect or constructive ownership: Attribution rules treat ownership held through another person or entity as relevant.
• Control relationship: Tax rules can treat persons as related because common control or specified family or entity relationships exist.

A foreign individual who owns 30% of a US corporation is a related party. A sister company under common qualifying control can also be related even though it owns no shares directly in the reporting corporation.

Review the controlled foreign corporation rules separately. CFC status uses different ownership rules and does not replace the Form 5472 related-party analysis.

The 25% shareholder test is only 1 route to related-party status; sections 267, 707, and 482 can create other relationships.

Understanding the 25% ownership threshold

A domestic corporation becomes a 25% foreign-owned corporation when 1 foreign person owns at least 25% of the vote or value, directly or indirectly, at any time during the tax year. Constructive ownership rules can also affect the result, so layered ownership needs a separate review.

The following 2 measurements matter for the threshold:

• At least 25% of the total voting power of all classes entitled to vote.
• At least 25% of the total value of all classes of stock.

Based on our client scenario at TFX: A foreign individual owns 100% of Foreign HoldCo, and Foreign HoldCo owns 30% of US Corp. The simplified ownership path is 100% × 30% = 30%, before applying any additional constructive ownership rules.

A simplified 30% indirect interest crosses the 25% threshold, but attribution rules can change a layered ownership result.

 

For family, partnership, trust, nominee, or multi-tier structures, read the IRS constructive ownership rules before treating the simple multiplication above as final.

Entity classification can also change which return applies. See how a Form 8832 entity classification election can alter federal tax treatment.

NOTE! A layered or nominee structure should not be tested with percentages alone. Section 318 attribution, as modified for Form 5472, can create ownership that is not obvious from the legal ownership chart.

Foreign-owned LLCs and disregarded entities

A US single-member LLC wholly owned by a foreign person is treated as a separate corporation only for limited section 6038A reporting rules. If it has a reportable transaction in 2025, it files Form 5472 with a pro forma Form 1120 even if the LLC has no taxable income.

The following 3 points explain the special treatment:

• The LLC remains disregarded for general federal income tax purposes unless it elected another classification.
• For section 6038A, it is treated as a reporting corporation so Form 5472 rules can apply.
• It uses a pro forma Form 1120 as the attachment vehicle for Form 5472.

Based on our client scenario at TFX: A non-US individual forms a Delaware single-member LLC in 2025 and contributes $2,000 to its bank account. The contribution is a Part V reportable transaction, so the LLC has a Form 5472 filing duty.

NOTE! No revenue does not mean no filing. A foreign-owner contribution, distribution, formation payment, or other Part V transaction can trigger Form 5472 for an otherwise inactive LLC.

Filing mechanics for foreign-owned LLCs

A foreign-owned US disregarded entity files Form 5472 with a pro forma Form 1120 and cannot use the normal corporate e-file route for this package. For a 2025 calendar-year filing, the original due date is April 15, 2026, unless a valid extension changes it.

The following 5 steps cover the filing mechanics:

1. Obtain an EIN for the foreign-owned US disregarded entity.
2. Prepare the limited pro forma Form 1120 required by the current IRS instructions.
3. Attach a complete Form 5472 for each related party that requires a separate form.
4. File the package by the applicable return due date, including a valid extension.
5. Keep the source records supporting ownership and every reportable transaction.

The following 4 items should be ready before filing:

• EIN and legal entity details.
• Foreign owner and related-party identifying details.
• Transaction dates, types, amounts, and supporting records.
• The pro forma Form 1120 and each required Form 5472.

The IRS’s corporate e-file page describes e-filing for standard corporate returns. Foreign-owned US DE Form 5472 packages use the special mail or fax procedure in the IRS’s special filing directions instead.

 

 

Our tax and financial recordkeeping guide gives general retention context. For Form 5472, keep records as long as they may be relevant under the section 6038A rules.

What counts as a reportable transaction for an LLC

For a foreign-owned US disregarded entity, Part V reaches transactions beyond ordinary business revenue and expenses. In 2025, that can include formation, dissolution, acquisition, disposition, contributions, and distributions when those items are not already reported in Part IV or VI.

The following 6 categories cover common LLC transactions:

• Capital contributions: Cash or property placed into the LLC by the foreign owner.
• Loans: Money lent between the LLC and a related party.
• Rent: Rent paid or received in a related-party transaction.
• Royalties: Payments for rights to use intellectual property.
• Reimbursements: Related-party payments that reimburse costs or expenses.
• Goods or services: Sales, purchases, or service payments involving a related party.

A payment to an unrelated foreign contractor is a separate reporting question. Our Form 1099 guide for foreign contractors explains that analysis.

A transaction can be reportable even when it produces no taxable profit, while an ordinary transaction with an unrelated party is not reportable merely because it crosses a border.

What triggers the filing requirements for Form 5472?

The Form 5472 filing requirements are triggered when a reporting corporation has a reportable transaction with a related party during the tax year. For a foreign-owned US DE, Part V broadens the transaction set, and the IRS instructions do not provide a general de minimis filing threshold.

The following 3 status checks identify the main trigger paths:

• A domestic corporation is at least 25% foreign-owned.
• A foreign corporation is engaged in a US trade or business.
• A foreign-owned US disregarded entity is treated as a reporting corporation for section 6038A.

The separate Form 5472 filing requirements then turn on the transaction facts. A qualifying entity with no reportable transaction may fall within an exception, while a foreign-owned DE funded by its owner can have a filing obligation with no business revenue.

If this happened in 2025 – a capital contribution, related-party loan, service payment, rent, royalty, or covered property transfer – review whether Form 5472 is due with the 2026 return.

Reportable transactions

Form 5472 reportable transactions include monetary items in Part IV, other transactions of a foreign-owned US DE in Part V, and nonmonetary items in Part VI. For 2025, a separate Form 5472 is generally filed for each related party involved in reportable transactions.

The following 5 monetary categories are common in Part IV:

• Sales or purchases of tangible property.
• Sales, purchases, or use of intangible property.
• Loans, interest, and other financial transactions.
• Rent, royalties, commissions, and service payments.
• Other amounts affecting taxable income that the form specifically requests.

The K-1 vs. 1099 guide can help distinguish separate recipient-reporting forms. Those forms do not replace Form 5472 when a related-party transaction independently falls within its rules.

Based on our client scenario at TFX:

1. A 30% foreign shareholder lends US Corp $80,000 during 2025. The loan is a related-party monetary transaction, so the corporation reports the amount in the applicable Form 5472 fields.
2. US Corp pays its foreign affiliate $45,000 for services during 2025. If the affiliate is a related party, the payment is a reportable transaction even though the amount is below $50,000.

 

Example scenarios

These 4 2025 scenarios show how entity status and transactions work together. A capital contribution or related-party loan can trigger filing, while an entity outside the reporting-corporation definition does not become a Form 5472 filer merely because it has a foreign vendor.

1. Foreign owner contributes cash. Based on our client scenario at TFX: A foreign owner contributes $5,000 to a wholly owned US DE. Conclusion: The contribution is a Part V reportable transaction, so Form 5472 is required.
2. Foreign affiliate makes a loan. Based on our client scenario at TFX: A 25% foreign-owned US corporation borrows $100,000 from a related foreign affiliate. Conclusion: The related-party loan is reportable.
3. No-income LLC receives funds. Based on our client scenario at TFX: A foreign-owned US DE has $0 revenue but receives $1,500 from its owner for expenses. Conclusion: The transfer can create a Part V filing duty.
4. Unrelated foreign vendor. A US corporation with no 25% foreign owner buys services from an unrelated foreign supplier. Conclusion: That fact alone does not make the corporation a Form 5472 reporting corporation.

What’s the difference between Form 5472 and Form 5471?

Form 5472 reports specified transactions of foreign-owned US corporations and certain foreign corporations with a US trade or business. Form 5471 reports foreign-corporation information for US persons meeting 1 or more filing categories, so there is no universal 10% ownership rule for Form 5471.

Form 5472 and Form 5471 use different filer definitions, entity directions, and ownership tests; neither form substitutes for the other.

 

The IRS Form 5471 page points filers to the current category rules. A Form 5472 and Form 1120 package is a different filing path from Form 5471 attached to a US person’s applicable return.

For a foreign-owned US DE, the phrase Form 5472 with Form 1120 refers to the special pro forma attachment method. It does not convert the disregarded entity into a C corporation for general federal income tax purposes.

Which one do I need? Start with ownership direction. Foreign ownership of a US reporting entity points toward Form 5472; a US person’s reportable interest in a foreign corporation points toward Form 5471, subject to each form’s full category rules.

Form 5472 filing deadline

Form 5472 is due with the reporting corporation’s return, including a pro forma Form 1120 for a foreign-owned US DE. For a 2025 calendar-year domestic corporate filer, the due date is April 15, 2026; a timely Form 7004 generally extends filing to October 15, 2026.

The due date changes with the filer’s tax year and return type. A foreign corporation filing Form 1120-F can have a different due date depending on whether it maintains a US office or place of business.

For 2025 calendar-year domestic filers, April 15, 2026 is the key date; fiscal-year and Form 1120-F filers must calculate their date from the applicable corporate return rules.

 

The following 3 deadline rules prevent common date errors:

• Form 5472 follows the due date of the return to which it is attached.
• A foreign-owned US DE follows its owner’s US tax year, or the calendar year if the owner has no US tax filing year.
• A June 30 fiscal-year corporation uses the special 15th-day-of-the-3rd-month rule.

See TFX’s 2026 tax extension guide for current extension context. The IRS’s Form 7004 e-filing page covers the business extension form used for qualifying returns.

Extension: How to use Form 7004

A Form 5472 extension follows the extension of the return to which the form is attached. For a 2025 calendar-year domestic corporation or foreign-owned US DE, filing Form 7004 by April 15, 2026 generally moves the filing deadline to October 15, 2026.

The following 3 steps cover a standard calendar-year filing:

1. Prepare Form 7004 for the return type used with Form 5472.
2. File it by the original April 15, 2026 due date for a calendar-year Form 1120 filing.
3. Complete and submit Form 5472 with the extended return package by October 15, 2026.

For a foreign-owned US DE, use the special Form 7004 mail or fax procedure stated in the current IRS filing directions. The IRS due-date and extension FAQ gives general e-file timing rules.

The following 2 points matter before relying on the extension:

• Form 7004 extends time to file, not time to pay tax that is due.
• C corporations with tax years ending June 30 and beginning before January 1, 2026 receive a 7-month extension under the December 2025 instructions.

 

 

The difference between individual extension forms is separate. See our guide to Form 4868 vs. Form 2350 rather than applying an individual expat extension to Form 5472.

Form 5472 instructions: How to file

The IRS requires Form 5472 to be attached to the reporting corporation’s applicable return by its due date, including extensions. For 2025, that can mean Form 1120, Form 1120-F, or a pro forma Form 1120 for a foreign-owned US disregarded entity.

The filing process has the following 3 stages:

1. Prepare the return attachment and source documents.
2. Complete the reporting-corporation, ownership, related-party, and transaction fields that apply.
3. Submit the form with the correct return package by the applicable due date.

Before you file Form 5472, collect the information listed in the next section. Use the official Form 5472 download on IRS.gov and current IRS instructions rather than an older saved copy.

Prepare to file

Preparation starts with 4 record groups: entity identification, ownership, related-party data, and transaction support. For the 2025 tax year, those records should reconcile to every Form 5472 filed and to the Form 1120 or Form 1120-F package used for submission.

The following 4 record groups should be ready:

• EIN and entity details: Legal name, address, tax year, business activity, and entity status.
• Ownership details: Direct and ultimate indirect foreign shareholders, ownership percentages, and countries.
• Related-party details: Name, address, identifying number when required, relationship, and country.
• Transaction records: Ledgers, bank records, invoices, agreements, contribution records, loan schedules, and property-transfer support.

A separate Form 5472 is generally required for each related party with which the reporting corporation had a reportable transaction. Keep the documents grouped by related party so transaction totals can be traced to the correct form.

Our tax documents checklist can help organize the broader return package before Form 5472 preparation begins.

Fill out the form

The Form 5472 instructions divide the filing into identification, ownership, related-party, and transaction sections. In the December 2024 revision, all reporting corporations complete Part VII, while Parts II, IV, V, and VI depend on filer status and the transaction type involved.

The following 6 fields or sections deserve a line-by-line check:

• Part I: Reporting corporation details and aggregate transaction information.
• Part II: 25% foreign shareholder data for a 25% foreign-owned US corporation, including a foreign-owned US DE.
• Part III: Related-party information.
• Part IV: Monetary transactions with a foreign related party.
• Part V: Other reportable transactions of a foreign-owned US DE.
• Part VI: Nonmonetary and less-than-full-consideration transactions with a foreign related party.

Part VII asks for additional information and is completed by all reporting corporations. Specialized later parts should be completed only when their stated rules apply.

The Form 1040 guide covers individual returns, which do not replace this entity filing. Foreign corporations should also review the Form 1120-F guide when the corporation itself has a US return obligation.

Based on our client scenario at TFX: US Corp files 2 Forms 5472 because it had reportable transactions with 2 related parties. Part I line 1g reports the total number of Forms 5472 filed for that tax year.

Exceptions and special cases

The IRS instructions list 6 filing exceptions, but 3 of them do not apply to foreign-owned US disregarded entities. For a foreign-owned DE, the no-reportable-transaction exception remains central because owner contributions and other Part V transfers can create a filing duty even with $0 revenue.

The following 4 edge cases deserve a separate check:

• No reportable transactions: A reporting corporation may qualify for the no-transaction exception.
• Multiple related parties: A separate Form 5472 is generally filed for each related party with a reportable transaction.
• Dormant foreign-owned US DE: No revenue alone does not establish an exception if owner funding or other Part V transactions occurred.
• Form 5471 overlap: A limited Form 5471/Schedule M exception can apply in specified cases, but not to a foreign-owned US DE.

A dormant entity can still have filing activity. The TFX guide to a dormant foreign corporation covers a different entity type and should not be used as a substitute for the foreign-owned US DE rules.

Special case: A foreign-owned US DE that had no Part IV, V, or VI reportable transaction may fit the no-transaction exception. Check formation, contributions, distributions, and owner-paid expenses before treating the entity as inactive.

Penalties for Form 5472 non-compliance & how to avoid them

A required Form 5472 that is late or substantially incomplete can trigger a $25,000 penalty. If the failure continues for more than 90 days after IRS notice, another $25,000 can apply for each 30-day period or fraction, with no statutory maximum continuation penalty.

The initial Form 5472 penalty is $25,000 per failure, and continuation penalties can keep increasing after the 90-day IRS notice period.

 

The following 4 mistakes are common causes of Form 5472 problems:

• Treating a zero-revenue foreign-owned LLC as having no filing duty.
• Missing a capital contribution, distribution, loan, or service payment.
• Using the wrong related-party or ownership analysis.
• Filing the Form 5472 package after the applicable return deadline.

Based on our client scenario at TFX: A corporation has 3 related parties and fails to file 3 required Forms 5472. The initial exposure can be $25,000 × 3 = $75,000 before any continuation penalties.

Reasonable cause can excuse the initial Section 6038A penalty when the corporation makes the required affirmative showing. The standard is fact-specific and requires a written statement with supporting facts; relief is not automatic.

An IRS Chief Counsel memo released April 24, 2026 discusses the small-corporation reasonable-cause rule. The memo is nonprecedential and does not change the $25,000 filing penalty.

Current IRS Appeals guidance defines a small corporation for that rule as one with gross receipts of $20 million or less. The special standard still depends on the stated conditions and a written reasonable-cause submission.

First-time abatement generally does not apply to this event-based penalty, subject to a narrow IRS administrative exception for certain systemically assessed Form 5472 penalties. Do not assume prior clean filing history by itself removes the $25,000 penalty.

For broader filing consequences, see TFX’s guide to late US tax return penalties. Our detailed Form 5472 penalty guide explains the information-return penalty structure and relief factors in more depth.

The following 4 actions help keep a 2025 filing on track:

• Confirm entity classification and ownership before the return is prepared.
• Reconcile every related-party transaction to supporting records.
• File each required Form 5472 with the correct return package on time.
• Address a missed filing promptly and document any reasonable-cause facts.
