Quick answer: If you are a non-US person who owns a US single-member LLC, the IRS almost certainly requires you to file Form 5472 every year — even if your LLC made zero dollars. The penalty for missing it is a flat $25,000 per form, per year, with no maximum cap. This guide explains exactly when the form is triggered, how to file it correctly, what the One Big Beautiful Bill Act (signed July 4, 2025) changed for 2026, and what to do if you have already missed a filing.
The promise of the US financial system is incredibly seductive to international founders. With a few hundred dollars and a Wi-Fi connection, a developer in Berlin or an agency owner in São Paulo can incorporate a Wyoming or Delaware LLC. Within days, you have a prestigious US corporate entity, a Stripe account, and a global business bank account.
The standard playbook is heavily promoted across the internet. Pay a registered agent. File the articles of organization. Start billing clients. Founders generally assume that because they don’t live in the United States and the LLC has no physical US presence, they don’t owe US taxes.
You may be entirely right about the taxes. But you are likely entirely wrong about the paperwork.
Buried deep in the US tax code is a reporting requirement designed specifically to make foreign-owned US entities transparent to the IRS. It catches thousands of location-independent entrepreneurs completely off guard every year.
That requirement is IRS Form 5472.
If you get it wrong — or if you simply do not know it exists — the IRS can hit your business with a $25,000 penalty. There is no leniency for ignorance, and the fine applies even if your LLC did not earn a single dollar.
In our practice at Basta + Croop, the most common version of this story we see goes like this: a founder forms a Wyoming or Delaware LLC in early 2024, builds a product all year, generates no revenue, and assumes there is “nothing to file.” We meet them in 2026 after they have received an IRS notice and are staring at penalties that could exceed the entire capital they put into the company. This article is designed to make sure that doesn’t happen to you.
What Form 5472 Actually Is (And Why the IRS Cares So Much)
The fundamental mistake foreign founders make is confusing a tax liability with an information reporting requirement.
As a non-US resident with a single-member LLC, your company is by default classified as a “disregarded entity” for US federal income tax purposes. In most cases, if you have no effectively connected income — no US office, no US employees, no dependent agent in the US — you do not owe US corporate income tax.
The IRS still wants to know exactly what your company is doing.
In 2016, the Treasury Department issued final regulations under Treasury Reg §1.6038A and §301.7701-2 that, beginning with the 2017 tax year, brought foreign-owned single-member LLCs under the Form 5472 reporting regime for the first time. The change was driven by a clear policy concern: foreign individuals were using anonymous US LLCs to move money internationally without leaving any reportable trail.
Form 5472 is not a tax return. It is an information return authorized under Internal Revenue Code §6038A and §6038C. Its job is to track “reportable transactions” between the US entity and its foreign owner or any related party. The IRS wants a transparent ledger of every time money or value moves between you in your home country and your LLC in the United States.
You can review the form itself directly on the IRS website: About Form 5472 and the Instructions for Form 5472.
The “Zero Activity” Myth That Costs Founders $25,000
This is where the trap snaps shut on most founders. Many foreign entrepreneurs incorporate an LLC, leave it dormant while they build, generate no revenue in year one, and assume “zero income” means “zero paperwork.”
This is a dangerous miscalculation.
Form 5472 is triggered by any reportable transaction with a related party. The IRS defines a reportable transaction broadly. It is not limited to sales revenue or contractor payments. It includes:
- Capital contributions. You wired $500 from your personal account in Spain to fund the LLC’s new US bank account. That is reportable.
- Formation costs paid personally. You used a personal credit card to pay your registered agent or the state filing fees to form the LLC. Reportable.
- Owner draws or distributions. You moved $100 from the business account back to yourself to test the wire. Reportable.
- Loans in either direction. You lent the LLC money to cover early expenses, or the LLC repaid you. Reportable.
- Non-cash transfers. You contributed software, intellectual property, or equipment to the LLC. Reportable.
- Services exchanged at no charge. You performed work for the LLC without invoicing it, or vice versa. The fair market value is reportable.
If money, property, or services moved between you and the LLC in any direction during the year, Form 5472 is on the table. As a practical matter, it is almost impossible to start and run a US LLC without triggering the requirement at least once.
The Anatomy of a $25,000 Penalty
The IRS does not treat Form 5472 non-compliance as an administrative slip-up. Under IRC §6038A(d), it is treated as an international transparency violation, and the penalty structure reflects that.
Baseline penalty: A flat $25,000 for failing to file Form 5472 on time, or for filing a “substantially incomplete” form. Up from $10,000 prior to mid-2018, when the penalty was increased as part of the wider TCJA-era enforcement push.
Per form, per year. If your structure has multiple foreign related parties, you file a separate Form 5472 for each one. A founder with a US LLC owned through a foreign holding company that also transacts with a foreign affiliate could easily owe two or three forms — meaning $50,000 to $75,000 in initial exposure for a single missed year.
Continuation penalties with no cap. If the IRS mails you a notice and you fail to comply within 90 days, an additional $25,000 is assessed for every 30-day period the form remains unfiled. Unlike most other international information return penalties, there is no statutory maximum. A founder who ignores notices for a year can compound penalties into six figures on a single dormant LLC.
No statute of limitations protection. Because the limitations period generally does not begin to run until the form is filed, the IRS can in many cases reach back across multiple years. We routinely meet clients facing six or seven years of accumulated exposure.
This penalty applies even if your LLC had $0 in revenue and owes $0 in US income tax. The penalty exists because of the missing paperwork, not because of any tax owed.
How to Actually File Form 5472
Filing Form 5472 is, frankly, an archaic process. Because a foreign-owned single-member LLC is a “disregarded entity,” it does not have its own income tax return to attach the form to. The IRS solves this with a workaround that is counterintuitive enough that even experienced US CPAs sometimes miss it.
Step 1: Get an EIN. You cannot file Form 5472 without an Employer Identification Number for the LLC. Even if you have no employees, the EIN is mandatory. Foreign founders without an SSN or ITIN typically apply by faxing or mailing Form SS-4.
Step 2: Prepare a Pro Forma Form 1120. Form 1120 is the standard US C-corporation income tax return. Even though your LLC is not taxed as a corporation, the IRS uses Form 1120 as a “cover sheet” for Form 5472. You complete only the basic identifying information (name, EIN, tax year), check the appropriate boxes, and write “Foreign-owned U.S. DE” across the top. The income, deductions, and tax calculation sections are left blank. The pro forma 1120 does not create any corporate tax liability.
Step 3: Attach Form 5472. This is where the actual disclosure happens. The form requires:
- Identifying information for the LLC (Part I)
- Identifying information for the 25%-or-more foreign shareholder (Part II)
- Information about related parties to whom reportable transactions relate (Part III)
- Dollar values, by category, of every reportable transaction during the calendar year (Part IV–VI)
Step 4: File by mail or fax. Foreign-owned disregarded entities cannot e-file the pro forma 1120 + Form 5472 packet. The IRS requires it to be sent to a dedicated processing unit:
Internal Revenue Service 1973 Rulon White Blvd, M/S 6112 Attn: PIN Unit Ogden, UT 84201
Or by fax to 855-887-7737.
Step 5: Hit the deadline. For calendar-year LLCs, the filing is due April 15 of the following year. If you need more time, you can file Form 7004 by April 15 to extend the deadline to October 15. The extension extends time to file, not time to pay — although for most foreign-owned disregarded entities with no effectively connected income, there is no tax liability to pay in the first place.
Step 6: Keep records for 7 years. Treasury Reg §1.6038A-3 requires the LLC to maintain records sufficient to verify the accuracy of every reportable transaction. Bank statements, invoices, intercompany agreements, transfer pricing documentation, and exchange rate sources should all be retained.
What Changed in 2025–2026: The OBBBA Update
Any current article on Form 5472 has to address the One Big Beautiful Bill Act (OBBBA), signed into law by President Trump on July 4, 2025 as Public Law 119-21. While the headline provisions of OBBBA are domestic, several elements directly affect foreign-owned US entities, beginning with tax years after December 31, 2025:
- 1% remittance excise tax (new IRC §4475). A 1% excise tax applies to certain cross-border remittance transfers initiated through a remittance transfer provider after December 31, 2025. Treasury and the IRS issued proposed regulations and Notice 2025-55 providing limited transitional relief for the first three quarters of 2026. The tax is collected by the provider, but the cash flow impact lands on senders moving funds out of the US — including, in many fact patterns, distributions from a US LLC back to its foreign owner. The exact scope is still being clarified through ongoing rulemaking.
- FTIN scrutiny. Foreign Taxpayer Identification Numbers are receiving heavier emphasis in the disclosure of foreign owners of US disregarded entities.
- NCTI / FDDEI rebrand and rate changes. GILTI is renamed Net CFC Tested Income (NCTI) and FDII is renamed Foreign-Derived Deduction Eligible Income (FDDEI), with deduction percentages set permanently at 40% and 33.34% respectively for tax years beginning after December 31, 2025. These changes do not directly alter Form 5472, but they may shift the underlying intercompany pricing structures the form is designed to surveil.
- BEAT rate. The Base Erosion and Anti-Abuse Tax rate is set at 10.5%.
Form 5472 penalty amounts themselves were not changed by OBBBA. The $25,000-per-form structure remains in effect. What has changed is that the broader enforcement environment around cross-border money movement is becoming more aggressive, not less.

Three Real-World Scenarios We See in Our Practice
These are composite examples drawn from typical fact patterns we encounter at Basta + Croop. Names and details are illustrative.
The Dormant Wyoming LLC. A SaaS founder in Portugal forms a Wyoming LLC in February 2024 to prepare for a US launch. He wires $2,000 of personal funds to the new business bank account to cover Stripe activation, a Mercury account, and registered agent fees. He never opens the company to customers. He believes he has nothing to file because he has no revenue. Reality: the $2,000 capital contribution and the formation expenses are reportable transactions. Form 5472 was due April 15, 2025. He is now exposed to the $25,000 penalty unless he files under the Delinquent International Information Return Submission Procedures with a reasonable cause statement.
The E-commerce Operator. A UK entrepreneur runs an Amazon FBA business through a Delaware LLC. She regularly wires profits from the LLC’s Mercury account to her personal UK account. Each transfer is a distribution and a reportable transaction. She files the LLC’s Form 5472 timely each year. Reality: she is doing the right thing — and beginning in 2026, she will also need to factor the new 1% remittance excise tax into her cash flow planning.
The Holding Company Stack. A German GmbH owns 100% of a Delaware LLC, which holds intellectual property and licenses it to an operating affiliate in Singapore. The Delaware LLC has reportable transactions with both the German parent and the Singaporean affiliate. Reality: two separate Forms 5472 are required for each tax year, plus arm’s-length transfer pricing documentation under Treasury Reg §1.482. Missing one form is $25,000. Missing both is $50,000.
What If You Already Missed the Deadline?
If you are reading this and realizing you missed a filing deadline for a US LLC, the natural reaction is to panic — or to dissolve the LLC and walk away. Both are bad ideas.
The single worst strategy is waiting for the IRS to find you. Once they issue a formal CP-215 or other notice, your options for leniency narrow significantly, and the 90-day continuation clock starts.
If you catch the mistake before the IRS contacts you, you have a defined path forward:
- Delinquent International Information Return Submission Procedures (DIIRSP). The IRS allows late-filed information returns to be submitted with a written reasonable cause statement. The standard, articulated in Treasury Reg §301.6651-1(c) and refined through case law, is whether you exercised “ordinary business care and prudence” but were nevertheless unable to comply on time.
- A well-crafted reasonable cause statement. This is not a paragraph. It is a structured narrative that addresses: who you are, why you formed the LLC, why you reasonably did not know about the requirement, the steps you took to comply once you discovered it, and the absence of any underlying tax avoidance motive.
- A complete catch-up package. Every year of delinquent filings is prepared and submitted together, not piecemeal.
- Documentation. Reliance on a tax advisor who failed to identify the requirement, language barriers, illness, and genuine first-time good-faith error are all factors the IRS weighs.
This is not a DIY project. Reasonable cause is fact-specific, the burden of proof is on the taxpayer, and a poorly drafted statement can lock in penalties that a stronger one might have eliminated.
Frequently Asked Questions
Do I need to file Form 5472 if my LLC made no money? Almost certainly yes. The form is triggered by reportable transactions, not income. Funding the LLC’s bank account or paying formation costs personally are themselves reportable transactions.
My LLC is a disregarded entity. Doesn’t that mean it has no tax obligations? “Disregarded” is an income tax classification. It does not eliminate information reporting obligations. Since 2017, foreign-owned disregarded entities have been treated as domestic corporations specifically for purposes of §6038A reporting.
Can I e-file Form 5472? No. Foreign-owned single-member LLCs filing the pro forma 1120 + Form 5472 packet must mail or fax the return to the dedicated Ogden, UT processing unit.
What is the deadline? April 15 for calendar-year LLCs. You can extend to October 15 by filing Form 7004 by April 15.
How long do I need to keep records? At least 7 years under Treasury Reg §1.6038A-3, including bank statements, invoices, intercompany agreements, and transfer pricing documentation.
Does a tax treaty between my country and the US exempt me? No. Form 5472 is an information return. Treaty positions affect substantive tax liability, not information reporting.
What if I dissolve the LLC — does that erase the obligation? No. Dissolving the LLC does not eliminate prior-year filing obligations or accrued penalties. In some cases it makes the situation worse by signaling avoidance.
Is Form 5472 the same as FBAR or BOI reporting? No. Form 5472 reports related-party transactions to the IRS. FBAR (FinCEN Form 114) reports foreign financial accounts held by US persons. BOI (Beneficial Ownership Information) is a separate FinCEN regime under the Corporate Transparency Act. A foreign-owned US LLC may face all three.
The Bottom Line
Accessing the US market is one of the most powerful levers available for global wealth creation. But it requires respecting the architecture of the US tax system. You cannot operate a borderless business on assumptions about a tax code you have not read.
Form 5472 is, fundamentally, an unforced error. Handled correctly, it is an annual administrative chore that takes a competent preparer a few hours. Ignored, it is an existential threat to your business — a $25,000 line item that compounds without limit and survives the dissolution of the LLC itself.
