Late Form 5472: Reasonable Cause and What Relief Actually Requires
A notice arrives assessing $25,000 against a company that has never made a profit, often several years after the year it relates to. The owner is outside the United States, formed the company through an online formation service, and has never heard of the form the penalty is about. This is one of the most common expensive surprises in inbound U.S. tax. It also has a defined route out of it, and understanding that route before anything is filed changes the outcome more than almost any other decision in the process.
What Form 5472 actually is
Form 5472, Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business, exists under IRC §6038A. It requires a "reporting corporation," defined in §6038A(a) as a domestic corporation that is 25 percent or more foreign-owned, to disclose transactions with related parties during the year. Since 2017, Treas. Reg. §301.7701-2(c)(2)(vi) extends the same regime to a domestic disregarded entity that is wholly owned by one foreign person. A single-member LLC owned by a non-resident, with no election to be treated as a corporation, still has to file a pro forma Form 1120 with Form 5472 attached, under the mechanics set out in Treas. Reg. §1.6038A-1 through §1.6038A-5.
The reported transactions include capital contributions, loans between the owner and the entity, distributions, and payments for services, rent, or other consideration moving in either direction. It is common for a dormant company that has never sold anything to still owe the filing, because the owner funding the company's bank account or paying its formation costs is itself a reportable transaction.
Why the penalty is the same for a company with no profit
Form 5472 is an information return, not a return that computes tax. The penalty under IRC §6038A(d)(1) is $25,000 per failure, and it does not scale with income, gain, or the size of the transactions that went unreported. A company with $40 in reportable capital contributions and no revenue owes the identical $25,000 as a company with eight million dollars moving through it. The penalty is for the absence of the disclosure, not for anything owed on the numbers inside it.
The penalty also runs per form, per year. A company that formed in 2021 and never filed is not looking at one $25,000 exposure. It is looking at one for 2021, one for 2022, one for 2023, one for 2024, and one for 2025, assuming a filing obligation existed in each of those years. Five years of silence produces a stated exposure of $125,000 before any continuation penalty is added, as shown below.
| Tax year missed | Base penalty under §6038A(d)(1) | Running total |
|---|---|---|
| 2021 | $25,000 | $25,000 |
| 2022 | $25,000 | $50,000 |
| 2023 | $25,000 | $75,000 |
| 2024 | $25,000 | $100,000 |
| 2025 | $25,000 | $125,000 |
This table reflects only the base penalty under §6038A(d)(1). It does not include the continuation amounts under §6038A(d)(2), which are described next, and which can apply on top of every figure shown here once a notice has been issued and the 90-day window has passed without a filed return.
The continuation penalty, and why a notice is a clock
IRC §6038A(d)(2) adds a second layer. If the failure continues for more than 90 days after the IRS mails notice of the failure, an additional $25,000 applies for each 30-day period, or fraction of one, that the failure continues beyond that 90-day window. There is no stated ceiling on how many of these additional amounts can accrue while the return sits unfiled.
This is the detail that turns a serious problem into an urgent one. The 90 days following a notice is the single most valuable period in the entire matter, and it is frequently spent doing nothing, because the recipient does not recognize what has arrived, assumes it is a scam, or sets it aside to deal with later. A notice under §6038A(d) is not a bill that can be paid and forgotten. It is a deadline with a penalty attached to missing it a second time.
What reasonable cause requires
Treas. Reg. §1.6038A-4 provides that the penalty does not apply if the reporting corporation shows that its failure to comply was due to reasonable cause and not willful neglect. This is evaluated under the general reasonable cause framework the IRS applies across information return penalties, described in IRM 20.1.9 for international penalties and IRM 20.1.1.3 for the reasonable cause standard generally. It is a facts-and-circumstances test. There is no fixed list of qualifying excuses, and the outcome depends on what the taxpayer actually knew, actually did, and actually documented, rather than on matching a template.
Arguments that tend to be given weight include a genuine, documented reliance on a paid professional or service provider who represented that the filing was being handled, circumstances outside the taxpayer's control that prevented timely filing, and prompt corrective action taken once the omission was discovered. Arguments that carry little weight on their own include simple unfamiliarity with the requirement. Not knowing a form existed is common, and it is not by itself reasonable cause. What can change the analysis is why the taxpayer did not know, particularly where a paid formation or "compliance" provider represented, in writing, that annual obligations were covered, when in fact the product purchased was limited to a state-level annual report and never touched the federal information return.
Worked example
A non-resident individual formed a Wyoming single-member LLC in March 2022 through an online formation platform, opting into an annual "compliance package" priced at $299 a year. The LLC opened a U.S. bank account, received capital contributions from the owner in 2022 and 2023, and made no sales. In late 2025 the owner received an IRS notice assessing $50,000, covering the pro forma Form 1120 and Form 5472 for both 2022 and 2023, which had never been filed.
On review, the "compliance package" turned out to cover only the state's annual report and registered agent renewal. Nothing in the platform's marketing or engagement terms referenced federal information return filing, and the owner had never been told a federal filing existed separately from the state one. That gap, documented through the platform's own terms of service and billing history, supported a reasonable cause statement submitted alongside the delinquent returns. It did not guarantee the penalty would be abated. It gave the position something to stand on.
The statement itself is not a form with boxes to check. It is a written narrative, attached to the delinquent Form 1120 and Form 5472 filings, that lays out the chronology: when the entity was formed, what the owner was told about ongoing obligations, what was actually purchased and delivered, when the gap was discovered, and what steps were taken once it was found. Supporting exhibits, such as the platform's terms of service, invoices, and any correspondence referencing "compliance" or "annual filings," are attached rather than summarized secondhand. A statement that asserts the facts without attaching the documents behind them carries far less weight than one that lets the IRS see the underlying record directly.
Why first-time abatement usually does not help
Taxpayers who have dealt with domestic penalties sometimes expect the IRS's First-Time Abate administrative waiver, described in IRM 20.1.1.3.6.1, to apply here. It generally does not. First-Time Abate is built around a taxpayer's compliance history with certain common penalties, and international information return penalties under §6038, §6038A, §6038B, §6038C, §6046, §6046A, and related sections are treated separately, outside that administrative waiver. Reasonable cause under Treas. Reg. §1.6038A-4 is the operative standard here, not a clean-history shortcut.
Is relief automatic once the missing years are filed?
No, and this is the most consequential misunderstanding in this area. Filing the delinquent pro forma returns with a reasonable cause statement attached does not guarantee the penalty will never be assessed. In practice, the statement is not always evaluated during initial processing, and a penalty notice can be generated automatically before anyone at the IRS has read the explanation. At that point the position has to be defended in response to the notice, through the normal penalty abatement and appeal channels, rather than treated as already resolved.
Anyone describing quiet, unexplained filing as a way to make the exposure disappear is describing an outcome nobody can promise. The realistic framing is that filing correctly, with a properly supported statement attached, puts the taxpayer in the best available position, and that a notice may still follow and may still need to be answered on its own terms.
Why the years never really closed
There is a consequence to unfiled information returns that often matters more than the penalty itself. IRC §6501(c)(8) provides that where a return or information required under sections including §6038 and §6038A has not been filed, the period the IRS has to assess tax with respect to the return generally does not begin to run in the ordinary way, and can remain open with respect to the item or items to which the missing information relates. A taxpayer who assumes a return filed six years ago is safely closed can be wrong, if a required information return for that year was never filed alongside it.
This cuts against waiting. Silence does not produce the closure that the passage of time normally delivers. Filing is what starts the clock running again.
Quiet disclosure is a poor choice
Filing the missing returns with no explanation at all, sometimes called a quiet disclosure, is a recognized pattern and a weak one. It forgoes the chance to present a reasonable cause case at the point where it is most naturally considered, alongside the delinquent filing itself, and it can be viewed unfavorably if the position is later examined. If the facts support relief, they should be presented deliberately, in writing, with the supporting documentation attached. If the facts do not support relief, that is worth knowing honestly before filing rather than discovering it after a penalty notice arrives.
How this differs from streamlined filing and voluntary disclosure
The Streamlined Filing Compliance Procedures exist for U.S. persons, meaning citizens, green card holders, and individuals who meet the substantial presence test, who failed to report foreign financial assets and pay tax on foreign income, where the conduct was non-willful. A non-resident whose only problem is an unfiled Form 5472 for a U.S. company is generally not the taxpayer that program was built for, and using it in that situation is usually a mismatch rather than a shortcut.
Separately, there is a voluntary disclosure practice for taxpayers with potential criminal exposure, described in IRM 9.5.11.9, which is a materially different process with materially different consequences. Where the facts suggest willfulness rather than an honest gap in understanding, the correct first call is to an attorney, and this firm coordinates with counsel on that question rather than making the willfulness assessment itself.
What to do first
Before anything is submitted, establish the scope. Identify every year in which a filing obligation existed, what reportable transactions occurred in each of those years, whether any notice has already been issued, and what the response deadline on that notice is. Then assemble the documentary record: engagement terms with any formation or compliance provider, what was represented in writing, what was actually delivered, and when the gap was discovered.
The sequence matters more than speed. A filing made before the scope is fully established is difficult to correct afterward, and a reasonable cause case is strongest when it is made once, completely, with the supporting evidence attached from the start rather than supplemented piecemeal after a notice has already been generated.
How this connects to the delinquent international return procedures
A late Form 5472 rarely arrives alone. The same non-resident owner who missed the pro forma Form 1120 and Form 5472 for a disregarded LLC has frequently also missed a Foreign Bank Account Report, or holds a separate foreign entity that should have triggered Form 5471 under §6038 or Form 926 under §6038B. Scoping a Form 5472 problem is a natural moment to check whether other information returns for the same years are also outstanding, because the delinquent filing procedures used for those forms follow the same reasonable cause logic described here, and filing them together, once, with one coherent narrative, is generally stronger than addressing each form in isolation as separate problems surface over time.
