A founder forms a single-member LLC, never makes a sale, and closes it eighteen months later. No income, no tax due, nothing to declare. Then a letter arrives assessing twenty-five thousand dollars. The Form 5472 penalty is $25,000 per missed filing, and it applies even when the company owes no tax at all. This is the Form 5472 penalty that catches most foreign-owned LLCs off guard.
This is not a rare edge case and it is not the IRS being unreasonable. It is the single most expensive misunderstanding in foreign-owned US company ownership, and it is entirely avoidable once you see how the rule is actually constructed.
The mistake hiding in plain sight
Almost every founder reasons like this: my LLC is a disregarded entity, I am not a US person, the company earned nothing connected to the United States, therefore I owe no US tax, therefore I have nothing to file.
Every step in that chain can be correct. The conclusion is still wrong, because it confuses two separate obligations.
Paying tax depends on income. If there is no US-connected income there is generally no tax.
Filing an information return depends on transactions. It does not depend on income, profit, or whether any tax is owed.
A foreign-owned single-member LLC is treated as a corporation for this specific reporting purpose, and must file an information return disclosing transactions between itself and its foreign owner. The penalty attaches to the failure to file, not to any unpaid tax. That is why it lands on companies that made no money — from the perspective of the rule, profit was never the question.
Who is exposed
You are within scope if all of these are true:
- Your LLC is formed in a US state.
- It has one owner, or is otherwise treated as disregarded.
- That owner is not a US person.
- There was at least one reportable transaction during the year.
Three of the four are structural facts about your company. The fourth is where almost everyone assumes they are safe and is not.
What counts as a reportable transaction
This is the heart of it. The term sounds like it means trading revenue. It does not. It means value moving between the LLC and its foreign owner or a related party, in either direction.
- Money you put in. Any capital contribution, however small.
- Money you took out. Any distribution or withdrawal.
- Loans in either direction, including informal ones with no paperwork.
- Expenses you paid personally on the company's behalf.
- Amounts owed between you and the company at the year end.
Read that list against a company that "did nothing". You paid the state filing fee. You paid the registered agent. You paid for a domain. If any of that came from your personal card, the company has a reportable transaction, and the obligation is live.
The formation itself is frequently the reportable transaction. This is why the penalty catches dormant companies so reliably — the moment of formation almost guarantees at least one.
Why the Form 5472 penalty is so large
The penalty is set at $25,000 per form, per year. It is not scaled to the size of the company, its revenue or the value of the transaction. A hundred-dollar capital contribution and a ten-million-dollar one carry the same exposure for a missed filing.
That seems disproportionate until you consider the purpose. The filing exists so that the IRS can see money moving between US entities and their foreign owners. A penalty scaled to transaction size would make small unreported movements essentially free, which is exactly the pattern the rule is designed to discourage. The deterrent has to be flat to work.
Two further points matter. The penalty is assessed per year, so three missed years is three separate assessments. And filing something substantially incomplete can be treated as not filing at all.
The cost of getting it right, by comparison
| Typical cost | |
|---|---|
| Preparing the filing yourself | A few hours, plus the records you should keep anyway |
| An accountant preparing it | $300 – $900 for a simple dormant company |
| Missing one year | $25,000 |
| Missing three years | $75,000, assessed separately |
There are few decisions in running a small company where the numbers are this lopsided.
The record that makes this easy
The filing asks for totals of money moving between you and the company. If you have kept a log, preparing it takes an evening. If you have not, you are reconstructing a year from bank statements and guessing which personal card charges were company expenses.
So from the day the company exists, keep one row per movement: date, amount, direction, and a one-line purpose. A spreadsheet is enough. Include the things that do not feel like transactions — the filing fee paid from your personal card, the agent renewal, the domain.
This single habit converts the most expensive compliance risk you face into a routine annual task. It is covered further in the annual compliance calendar.
Timing, and the extension that exists
The filing is due with the company's annual return, generally in mid-April for a calendar-year company. An extension is available and it extends the time to file, not the time to pay anything that happens to be owed.
Two practical notes. The extension must be requested before the original deadline, not after you have realised you missed it. And an extension does not make the underlying obligation optional — it moves the date and nothing else.
Set the reminder for March rather than April. The information the filing needs is straightforward, but chasing a bank for twelve months of statements takes longer than anyone expects.
If you have already missed a year
This is recoverable more often than founders assume, and the worst response is to do nothing in the hope it is not noticed.
- Establish which years are affected. Every year in which a reportable transaction occurred, including the formation year.
- Assemble the records for each of those years. Bank statements, and card statements for anything paid personally.
- Get professional help before filing. This is the specific situation where an accountant experienced with foreign-owned entities earns their fee several times over.
- File voluntarily, with a reasonable cause statement. Filing before the IRS contacts you is materially better than filing after. The statement should explain honestly what happened — not knowing the requirement existed is a common and unembellished explanation.
- Do not invent a better story. A truthful account of a genuine misunderstanding is more credible than a constructed one, and a false statement converts a filing failure into a far more serious problem.
Relief is discretionary and never guaranteed. But voluntary correction with an honest explanation is the strongest position available, and it is meaningfully stronger than being found.
A worked example
An illustration makes the rule concrete in a way the statutory language does not.
A founder living in Morocco forms a Wyoming LLC in March. She pays the state filing fee of around a hundred dollars from her personal card, along with a registered agent for a hundred and twenty, and forty for a domain. She intends to launch a small software product, gets busy with client work, and never launches. The company makes no sales at all. In December she transfers three hundred dollars into the company account to cover the next year of fees.
By the ordinary reading, nothing happened. No revenue, no customers, no tax owed. By the rule that matters, four reportable transactions happened: three expenses she paid personally on the company's behalf, and one capital contribution. The obligation to file was triggered in the first month of the company's life and she has no idea it exists.
If she files, the return reports a few hundred dollars of transactions, no tax is due, and the matter ends. If she does not, the exposure is twenty-five thousand dollars for that year alone, and it repeats for every subsequent year in which she pays the agent renewal from her own card — which is to say, every year the company continues to exist.
The total value of the transactions across three years might be under a thousand dollars. The exposure would be seventy-five thousand. That gap is the entire reason this article exists.
Multi-member LLCs are a different regime
Everything above concerns a single-member LLC treated as disregarded. Adding a second member changes the picture, and founders sometimes hear "the 5472 rule" and assume it applies to them identically when it does not.
An LLC with two or more members is by default treated as a partnership, and a partnership has its own filing regime with its own returns, its own schedules for each partner, and its own penalty structure. Those penalties are generally calculated per partner per month rather than as a single flat amount, which makes them smaller for a short delay and capable of growing substantially over a long one.
The practical point is not the detail of either regime. It is that adding a partner is not a minor administrative change — it moves the company into a different set of obligations with different deadlines. That is worth knowing before you agree to it rather than after, particularly where the second member is in another country again.
How ownership across borders works in practice is covered in a multi-member LLC with partners in different countries, which is outside the scope of the Form 5472 penalty covered here.
What this means when you close the company
Founders who decide an LLC was a mistake often stop paying the agent and let the state dissolve it administratively. That ends the state registration. It does not retroactively remove the filing obligations for the years the company existed and had transactions.
Closing down properly — final filings included — costs a few hundred dollars and closes the exposure. Walking away costs nothing now and leaves an open question behind you.
Why nobody warned you
It is reasonable to ask how a requirement this expensive goes unmentioned by the people who set the company up.
Part of it is timing. The rule reached single-member foreign-owned LLCs comparatively recently, and a great deal of the advice circulating online predates that change. Guidance written in good faith five years earlier is simply wrong now, and it does not carry a date stamp.
Part of it is scope. Formation agents file documents with a state. Tax filing is a separate profession with separate qualifications, and many formation services are careful not to stray into it. That caution is defensible, but it leaves a gap exactly where a founder most needs to be told something.
And part of it is that the obligation is genuinely counter-intuitive. Every instinct says a company with no income has nothing to file. The rule is built the other way round, and instinct does not warn you about it.
The short version
The obligation is triggered by transactions, not profit. Forming the company is usually itself a transaction. The penalty is flat, large, and assessed per year. And the work that avoids it is a spreadsheet and one annual filing.
The mechanics of the form are covered in Form 5472 for a foreign-owned LLC, and the broader question of what a non-resident owner actually owes is in do non-resident LLC owners owe US tax. If you would rather this were tracked for you from the start, it is part of our formation service.
If you would rather have this handled for you, our US LLC formation service covers it end to end. For the official position, see IRS: About Form 5472.
