Form 5472 Filing Instructions: Transactions, Deadlines, Penalties

Form 5472 is filed as an attachment to the reporting corporation’s income tax return, with one form for each foreign related party the corporation had reportable transactions with during the tax year. These Form 5472 filing instructions cover who has to file, what to put on the form, where to send it, and what happens if you miss the deadline. The penalty starts at $25,000 per form, so getting this right matters even for entities with modest activity.¹

Who Has to File

Two kinds of entities file Form 5472: a U.S. corporation that is at least 25% foreign-owned at any point during the tax year, and a foreign corporation engaged in a trade or business within the United States. Either way, the obligation only kicks in when the entity had a reportable transaction with a related party during the year. No reportable transactions, no filing.²

A U.S. corporation is 25% foreign-owned when a single foreign person holds at least 25% of either the total voting power or the total value of all stock. Only one of the two measures needs to cross the line, and the test applies at any point during the year, not just year-end.³ The 25% test also picks up constructive ownership under IRC Section 318 with a modification that lowers the entity attribution threshold from 50% to 10%, so stock held by family members and related entities can be pulled into the calculation.⁴

A “related party” for this form is broader than a corporate group. It includes the 25% foreign shareholder itself, anyone related to the reporting corporation or that shareholder under IRC Sections 267(b) or 707(b)(1), and anyone related to the reporting corporation under the transfer pricing rules of Section 482. That last category sweeps in sibling companies, upper-tier entities, and other affiliates that share an ownership chain.³

File a separate Form 5472 for each related party. If your U.S. subsidiary transacted with its foreign parent, the parent’s sister company, and a foreign grandparent entity in the same year, that is three Forms 5472.⁵

Foreign-Owned Disregarded Entities

Foreign-owned U.S. disregarded entities, typically single-member LLCs owned by a foreign person, are treated as corporations solely for Form 5472 purposes. The LLC remains disregarded for all other tax purposes, but for information reporting under Section 6038A it is reclassified as a domestic corporation.⁶ Many foreign entrepreneurs form a U.S. LLC without realizing they have a corporate-level filing obligation. If any reportable transaction occurred with the foreign owner — including a capital contribution to set up the entity — the form is required.

The disregarded entity needs its own EIN. Foreign owners without an ITIN or SSN cannot use the online EIN application and typically apply by fax or mail, which takes several weeks. Start that step early.

What Counts as a Reportable Transaction

A reportable transaction is any exchange of money, property, or services between the reporting corporation and a related party. Monetary items reported in Part IV include:

Sales and purchases of tangible goods
Rents, royalties, and license fees
Service fees, management fees, and commissions
Interest paid or received on intercompany loans
Insurance premiums paid or received
Capital contributions and distributions
Loan principal borrowed or lent during the year

Non-monetary transactions and less-than-full-consideration transfers go in Part V with a description of what was exchanged and the fair market value. Part IX covers base erosion payments under Section 59A: deductible payments made to foreign related parties and the corresponding tax benefits claimed.⁴

Deadlines and Where to Send It

Form 5472 attaches to the reporting corporation’s income tax return. For a U.S. corporation, that is Form 1120. For a foreign corporation engaged in a U.S. trade or business, it is Form 1120-F. The deadline is the same as the underlying return: the 15th day of the fourth month after the close of the tax year, which is April 15 for calendar-year filers.⁷

Filing Form 7004 grants an automatic six-month extension for the entire return package, including the attached Form 5472.⁸ If you e-file the corporate return, the Form 5472 goes with it electronically.

Foreign-owned disregarded entities file differently. Because the DE does not file a regular corporate return, it submits a pro forma Form 1120 with only the entity’s name, address, and EIN filled in, and “Foreign-Owned U.S. DE” written across the top. The pro forma return exists solely to carry the Form 5472. Mail the package to:

Internal Revenue Service
1973 Rulon White Blvd
M/S 6112 Attn: PIN Unit
Ogden, UT 84201⁴

The Ogden address applies regardless of the state of incorporation; the mailing addresses used for a normal Form 1120 do not apply here. The deadline is still the 15th day of the fourth month after the tax year ends, and Form 7004 extends it by six months.

Filling Out the Form

Form 5472 has several parts. The first three collect identifying information; the later parts capture the transactions themselves.

Part I covers the reporting corporation: name, address, EIN, principal business activity code, total assets, the total number of Forms 5472 being filed for the year, and the total dollar amount of gross payments across all of them.⁵

Part II identifies the 25% foreign shareholder — name, address, country of incorporation, and foreign taxpayer identification number. If there is an ultimate indirect 25% foreign shareholder further up the ownership chain, put their information on separate lines. The IRS wants the top of the ownership structure visible, not only the direct shareholder.

Part III identifies the related party involved in the transactions and asks for a relationship code describing the connection, such as a controlled subsidiary or common parent.

Part IV is the core of the form. Each line corresponds to a category of monetary transaction; enter the aggregate dollar amount for each category. Report everything in U.S. dollars, and document the exchange rate methodology you used. The totals should tie back to your general ledger, because discrepancies between what appears on Form 5472 and what shows up elsewhere on the income tax return are the kind of thing that draws examiner attention.⁴

Part V captures non-monetary and less-than-full-consideration transfers with a description of the property or services and its fair market value. For intangible property transfers such as patent licenses, keep a valuation study available. You do not file the study with the form, but you need it if the IRS asks.

Part IX reports base erosion payments and related tax benefits under Section 59A. Enter the total amount of deductible payments made to the foreign related party and the corresponding deductions claimed.

The form also asks the corporation to confirm that all necessary books and records are maintained in the United States, or that a formal agreement about record access is in place. Do not check that box casually. A failure to maintain adequate records carries its own $25,000 penalty under the same statute.¹

Records You Need to Keep

The statute requires records sufficient to determine the correct tax treatment of transactions with related parties, kept in the United States.¹ In practice that means general ledger detail for every intercompany account, invoices and contracts supporting each transaction, transfer pricing documentation showing amounts are at arm’s length, and the exchange rate methodology used. For non-monetary transactions involving intangibles, keep any valuation studies or appraisals supporting the fair market value reported.

If keeping all records in the United States is not practical, the corporation can enter into an agreement with the IRS about record access. Failure to maintain the records triggers the same $25,000 base penalty as failure to file, with the same escalation after an IRS notice.

Exceptions to Check Before Filing

A few situations excuse the filing even when the entity would otherwise qualify:²

No reportable transactions of the types listed in Parts IV, V, or VI during the year.
A U.S. person controlling the foreign related corporation already files Form 5471 with a completed Schedule M covering all the reportable transactions. This does not apply to foreign-owned disregarded entities.
The related corporation qualifies as a foreign sales corporation and files Form 1120-FSC. Again, not available to disregarded entities.
A foreign corporation with no permanent establishment in the United States under an applicable income tax treaty, if it timely files Form 8833 disclosing the treaty position.
A foreign corporation whose gross income is entirely exempt under Section 883, if it fully complies with the reporting requirements of Sections 883 and 887.
Both the reporting corporation and the related party are non-U.S. persons and the transactions will not generate any U.S.-source income or deductions allocable to such income. Not available to disregarded entities.

The exception that trips people up most often is the assumption that a disregarded entity with minimal activity is off the hook. It is not, as long as any reportable transaction occurred with its foreign owner.

What Happens if You Miss the Deadline

The penalty for failing to file a timely and complete Form 5472 is $25,000 per form, per tax year, and the same amount applies separately for failing to maintain required records.¹ If the IRS sends a notice and the corporation does not comply within 90 days, another $25,000 accrues for every 30-day period (or partial period) the failure continues after that window. There is no cap on the continuation penalty.⁹

These penalties stack per form. A U.S. LLC owned by a foreign individual that transacted with two foreign related parties and failed to file for three years has six unfiled Forms 5472 and $150,000 of initial exposure before any continuation penalties.

There is a second consequence that is often more dangerous than the dollar penalty. Under IRC Section 6501(c)(8), the normal three-year assessment period does not start until the required information return is furnished. Skip the Form 5472 and the IRS can audit and assess tax for that year indefinitely. Once you do file, the three-year clock starts from the date of that filing, not the original due date.¹⁰

Reasonable Cause

The statute provides a reasonable cause defense. Under IRC Section 6038A(d)(3), the penalty clock does not begin earlier than the last day on which reasonable cause existed for the failure. The IRS evaluates whether you exercised ordinary business care and prudence but were still unable to comply. A clean compliance history, reliance on professional tax advice, circumstances genuinely beyond your control, and prompt filing once you discovered the obligation all help. A pattern of noncompliance, failure to disclose foreign ownership to your preparer, and ignoring professional advice hurt.

If you are requesting abatement, attach a written reasonable cause statement to the delinquent form. Cover the taxpayer’s name and EIN, the tax years involved, the circumstances that led to the failure, the steps taken to comply, why compliance did not happen, what you have done to fix it, and a statement that the failure was not intentional.

Delinquent Filing Procedures

If you find you should have been filing in prior years but were not, the IRS has delinquent international information return submission procedures. Taxpayers who are not already under civil examination or criminal investigation and have not been contacted about the missing returns can file through normal channels.¹¹

Attach each delinquent Form 5472 to an amended income tax return (Form 1120-X) for the applicable year and file according to the normal amended return instructions. Include a reasonable cause statement with each form. The IRS warns that penalties may still be assessed during processing without initially considering the reasonable cause statement, so expect to respond to follow-up correspondence and resubmit your documentation.

Filing voluntarily before the IRS contacts you is almost always the better route. Delinquent submissions do not automatically trigger an audit, and voluntary filing strengthens the reasonable cause argument if penalties are proposed.
