How to avoid penalties on Form 5472: A guide for foreign-owned US corporations
Form 5472 carries a $25,000 penalty per form per year for failure to file, failure to maintain required records, or filing a substantially incomplete return under IRC §6038A. Form 5472 penalties have no statutory maximum cap, so multiple years and multiple related parties can produce six-figure assessments.
This guide explains who must file Form 5472, how the full penalty structure works, the 5 most common filing mistakes, and 4 practical penalty-relief paths after a missed deadline, including Delinquent International Information Return Submission Procedures relevant to US expats operating US entities from abroad.
The guide also covers Form 5472 filing requirements for foreign-owned entities operating from abroad during the 2025 tax year, filed in 2026.
Who must file Form 5472
Form 5472 must be filed by a US corporation that is at least 25% foreign-owned and has had a reportable transaction with a related party during the tax year.
Since tax years beginning on or after January 1, 2017, a foreign-owned domestic disregarded entity, including a single-member LLC, must also file Form 5472 with a pro forma Form 1120 under Treasury Regulations §1.6038A-1.
The following 2 entity types account for most Form 5472 filings:
- a 25% foreign-owned US corporation and
- a foreign-owned domestic disregarded entity.
The foreign-owned disregarded-entity rules are a common trap because the filing obligation exists even when the entity has no taxable income.
Foreign founders who need a simpler overview of foreign-owned single-member LLC filing requirements should review the LLC-specific rules before the first return is due. The filing trigger depends on ownership status and a reportable transaction, not on profitability.
Form 5472 penalty structure: how $25,000 becomes much more
The base Form 5472 penalty is $25,000 per form per year under IRC §6038A(d)(1). If the failure continues for more than 90 days after the IRS mails a notice, an additional $25,000 penalty applies for each 30-day period or fraction of a period under 26 US Code §6038A. Form 5472 penalties have no statutory maximum cap, unlike Form 5471, which caps at $60,000 per year.
A single missed Form 5472 can escalate from $25,000 to $100,000 or more within months after IRS notification, and section 6038A sets no statutory ceiling.
| Filing status | Total penalty |
|---|---|
| Initial failure to file, maintain records, or file a complete return for one form and one year | $25,000 |
| Failure continues for more than 90 days after the IRS notice | $50,000 |
| Failure continues more than 90 days after the IRS notice, plus 30 more days | $75,000 |
| Failure continues more than 90 days after the IRS notice, plus 60 more days | $100,000 |
A company with 3 related parties that misses 2 years can face 6 forms × $25,000 = $150,000 in base penalties before the continuation period begins.
Criminal penalties for willful violations
Willful Form 5472 violations can trigger criminal exposure under IRC §7203, and the Form 5472 instructions also reference IRC §§7206 and 7207. Under IRC §7203, a willful failure to file can carry a fine of up to $25,000 for an individual, up to 1 year in prison, or both, while corporations face a higher maximum fine.
Willfulness is established when the taxpayer had knowledge of the filing requirement and intentionally disregarded it, not simply forgot or was unaware.
How Form 5472 penalties differ from Form 5471
- Form 5471 penalties start at $10,000 per form per year and can rise to a total of $60,000 after continuation penalties.
- Form 5472 penalties start at $25,000 per form per year and have no statutory maximum cap, which makes the exposure materially higher in multi-party or multi-year cases.
Taxpayers should not rely on the original Tax Court decision in Farhy as a current assessment defense. The D.C. Circuit reversed Farhy on May 3, 2024, and the Second Circuit again supported IRS assessment authority in Safdieh v. Commissioner and IRS Form 5471 penalty authority on February 27, 2026.
Five common Form 5472 mistakes that trigger penalties
The following 5 Form 5472 mistakes account for a large share of penalty notices: missing the filing deadline, not filing for a foreign-owned LLC, omitting nonmonetary transactions, filing one combined form for multiple related parties, and assuming a zero-activity entity is automatically exempt.
- Missing the filing deadline. Form 5472 is generally due with the return on April 15 for a calendar-year C corporation and April 15 for a calendar-year foreign-owned single-member LLC filing a pro forma Form 1120. Form 7004 grants an automatic 6-month extension only if filed by the original due date.
- Not filing for a foreign-owned single-member LLC. A foreign-owned LLC can owe a Form 5472 filing even when revenue is $0. Based on a TFX client scenario: a non-US founder forms a Delaware single-member LLC, contributes $5,000, earns no income, and still has a reportable transaction because the capital contribution itself is reportable, so he received a $25,000 IRS penalty notice in 2025 for tax year 2023.
- Omitting nonmonetary transactions. Property transfers, royalty-free intellectual property use, services provided without cash payment, and below-market arrangements can all be reportable transactions. The regulations require fair market value reporting even when no money changes hands.
- Filing one form for multiple related parties. A separate Form 5472 is required for each related party. Filing one combined form for 2 related parties leaves 1 required form missing, and the IRS can treat the missing form as a separate $25,000 penalty exposure.
- Treating a dormant or zero-activity LLC as exempt. A foreign-owned LLC with no sales, no payroll, and no bank activity can still have a reportable transaction. Initial funding, formation transfers, and owner-paid expenses are common examples that keep Form 5472 on the table.
How to avoid Form 5472 penalties: 5 steps
To avoid Form 5472 penalties, complete the following 5 steps: confirm the filing obligation before year-end, file by the original due date or extend with Form 7004, report every reportable transaction, including noncash items, file a separate form for each related party, and maintain permanent supporting records for 6 years minimum.
- Confirm the filing obligation. Determine whether a foreign person directly or indirectly owns at least 25% of the corporation, or whether the entity is a foreign-owned domestic disregarded entity. Ownership attribution can apply through chains of entities, so review the IRS constructive ownership rules before the year closes.
- File by the deadline or extend via Form 7004. For calendar-year filers, the Form 5472 deadline is generally April 15 because it travels with Form 1120 or the pro forma Form 1120. File Form 7004 by April 15 to secure an automatic 6-month extension, which generally moves the deadline to October 15.
- Report all reportable transactions completely. Track loans, rents, royalties, sales, services, contributions, distributions, and nonmonetary transactions throughout the year. The regulations reach less-than-full-consideration and noncash items, so assign fair market value when cash is absent.
- File one Form 5472 per related party. Count each foreign and domestic related party separately. Prepare one form for each related party, attach all forms to the same return package, and include identifying information such as the related party’s name, country, and tax identification details when required.
- Maintain permanent records. Section 6038A uses a permanent-record standard, so contracts, invoices, bank statements, loan agreements, and similar support should be retained indefinitely. If your internal document-retention policy uses a 6-year minimum for backups or duplicates, present that as an internal policy – not the legal rule.
How to get penalty relief if you already missed Form 5472
Taxpayers who missed Form 5472 usually evaluate 4 practical penalty-relief paths:
- reasonable cause,
- delinquent international information return filing with a reasonable cause statement,
- limited First-Time Abatement situations tied to systemically assessed penalties, and
- Form 843 after assessment.
The right option depends on whether the IRS has already issued a notice and how the penalty was assessed.
Reasonable cause defense
A taxpayer can request penalty abatement by showing reasonable cause and ordinary business care and prudence. Strong fact patterns include written reliance on incorrect professional advice, serious illness, natural disaster, or prompt correction after discovering the foreign-owned disregarded-entity rules.
The reasonable cause statement should be detailed, dated, and filed with the delinquent return or with the penalty response.
Delinquent International Information Return Submission Procedures
The IRS says taxpayers using the Delinquent International Information Return Submission Procedures must not be under an IRS civil examination or criminal investigation and must not already have been contacted by the IRS about the delinquent information returns. Eligible taxpayers file the delinquent returns through normal filing procedures and can attach a reasonable cause statement to each late form.
“The biggest thing is to do this before the IRS comes to you. If the IRS reaches out first, you may no longer be eligible.”
– Wendy Christiansen, CPA, Tax Supervisor at Taxes for Expats.
Penalty relief for Forms 5471, 5472, and 8865 explains why this route is still useful for self-correcting taxpayers. The procedure is most effective when the missed filing is discovered before an IRS notice arrives, and the submission package is complete on the first filing.
The IRS specifically says penalties may still be assessed under existing procedures, including the $25,000 Form 5472 penalty entirely when the 3 eligibility conditions are met – no amended prior returns required beyond what is submitted with the delinquent form.
First-Time Penalty Abatement
First-Time Penalty Abatement is not a broad stand-alone waiver for every Form 5472 penalty. Current IRS manual guidance limits routine FTA treatment because Form 5472 is an event-based information return, although some systemically assessed initial penalties tied to a late Form 1120 may be abated when the related return qualifies, and the compliance history is clean.
Taxpayers can still call the IRS Business and Specialty Tax Line at 800-829-4933 to confirm how the penalty was coded and whether any administrative relief path is available. When FTA is unavailable, reasonable cause or Form 843 is usually the stronger route.
Form 843 – formal claim after penalty assessment
If the IRS has already assessed a Form 5472 penalty, Form 843 is the standard administrative claim for refund or abatement. File Form 843 with the penalty notice, the delinquent Form 5472 if still missing, a complete reasonable cause statement, and supporting documents. Form 843 does not automatically stop collection, so deadlines on the IRS notice still matter.
The 4 penalty-relief options differ by timing, eligibility, and assessment status, so the best route depends on whether the IRS has already mailed a notice and how the penalty entered the system.
| Relief option | Who qualifies | Requires delinquent return? | Penalty waived if approved? | Best for |
|---|---|---|---|---|
| Reasonable cause | Taxpayers with documented facts showing ordinary business care and prudence | Yes | Yes | One-time oversight, professional advice error, illness, disaster |
| Delinquent international information return filing | Taxpayers not yet contacted by IRS and not under exam | Yes | Possible, but not guaranteed | Late-discovered obligation found before IRS contact |
| First-Time Penalty Abatement | Limited cases involving systemically assessed penalties linked to related return history | Usually yes | Possible in limited cases | Penalty tied to late Form 1120 with clean filing history |
| Form 843 | Taxpayers seeking formal post-assessment review or refund | Usually yes, if the return is still missing | Partial or full | After receiving an IRS penalty notice or after payment |
All 4 options require the delinquent Form 5472 to be filed before or simultaneously with the relief request, except Form 843, which is filed after IRS assessment
Form 5472 requirements for foreign-owned single-member LLCs
A foreign-owned domestic single-member LLC is disregarded for most US income tax purposes, but it has been required to file Form 5472 with a pro forma Form 1120 since January 1, 2017, under Treasury Regulations §1.6038A-1. The filing obligation can apply even when the LLC earned zero income during the year.
Filing mechanics for foreign-owned LLCs
The pro forma Form 1120 for a foreign-owned single-member LLC generally includes identifying information rather than a full corporate income statement. The LLC must have an EIN before filing, and the IRS instructions direct foreign-owned domestic disregarded entities to attach Form 5472 to the pro forma Form 1120 and file it using the address or fax instructions listed in the current Form 5472 instructions.
A foreign owner without an SSN or ITIN can still obtain the EIN through Form SS-4 using the current IRS instructions for foreign applicants. The filing package for a foreign-owned domestic disregarded entity is not the same as a standard corporate Form 1120 return.
Coordination with FBAR and Form 8938 for US expats
A US citizen or US resident living abroad remains a US person under IRC §7701 and does not become a foreign owner solely by living outside the United States. A foreign-owned LLC exists only when the owner is not a US person, but US expats can still have parallel personal reporting obligations involving FBAR filing requirements and deadlines in 2026 and Form 8938 filing requirements for 2026.
FBAR is due April 15 with an automatic extension to October 15, while Form 8938 is filed with the individual income tax return. Coordinating those deadlines with a business-entity filing calendar helps avoid separate information-return penalties in the same year.

FAQ
The following 12 questions cover the most common Form 5472 penalty scenarios based on TFX client cases and IRS guidance current as of April 2026.
The IRS imposes a $25,000 penalty per Form 5472 per tax year for failure to file, failure to maintain required records, or filing a substantially incomplete return under IRC §6038A(d)(1). If the failure continues for more than 90 days after an IRS notice is mailed, another $25,000 applies for each 30-day period or fraction of a period under IRC §6038A(d)(2).
Form 5472 must be filed by a US corporation that is at least 25% foreign-owned and has had at least 1 reportable transaction with a related party during the tax year. A foreign-owned domestic single-member LLC must also file Form 5472 with a pro forma Form 1120 under Treasury Regulations §1.6038A-1.
Yes. A foreign-owned single-member LLC with zero revenue can still have a Form 5472 filing obligation if it had any reportable transaction during the year. Initial capital contributions, owner-paid costs, formation transfers, loans, and distributions are common triggers even when profit is $0.
For a calendar-year C corporation, Form 5472 is generally due on April 15 with Form 1120. For a calendar-year foreign-owned domestic disregarded entity filing a pro forma Form 1120, the deadline is also generally April 15. Filing Form 7004 by the original due date usually extends the filing deadline to October 15.
Yes. Reasonable cause is the main penalty-abatement route, and strong requests usually include a detailed written statement plus supporting documents. Depending on timing, taxpayers may also use the delinquent international information return process before IRS contact or Form 843 after a penalty assessment has already been made.
One Form 5472 is required for each related party with whom the reporting entity had reportable transactions during the year. A company with 3 related parties generally needs 3 separate Forms 5472. A combined filing for multiple related parties does not satisfy the separate-form requirement.
The notice matters because section 6038A(d)(2) starts a 90-day continuation period after the IRS mails the notice. If the filing failure is not corrected within that 90-day period, another $25,000 can apply for each additional 30-day period or fraction of a period that the failure continues.
No. Form 5472 penalties under section 6038A have no statutory maximum cap. A company with 3 related parties and 2 missed years can face 6 base-form penalties of $25,000 each, or $150,000, before any continuation penalties are added after an IRS notice.
A reportable transaction is an exchange involving money, property, services, rights, or obligations between the reporting entity and a related party. Sales, purchases, rents, royalties, loans, services, capital contributions, distributions, and certain formation or dissolution events can all qualify, including noncash transactions reported at fair market value.
Taxpayers should assume yes. The original Tax Court decision in Farhy is no longer a reliable current defense after the D.C. Circuit reversed it on May 3, 2024, and the Second Circuit again supported IRS assessment authority in Safdieh v. Commissioner on February 27, 2026.
No. Streamlined Foreign Compliance Procedures are designed for eligible individual taxpayers and are not the dedicated relief program for a missed Form 5472 by a corporation or foreign-owned disregarded entity. Taxpayers usually evaluate reasonable cause, delinquent information return filing, or Form 843 instead.
The Form 5472 record rules require permanent books and records sufficient to establish the correctness of each filing. A 6-year retention policy can be a practical minimum for supporting documents, but the regulation itself uses a permanent-record standard rather than a simple 6-year rule.
