Form 5472: The $25,000 Filing Most Single-Member LLC Owners Never Hear About

Short answer: if you are a non-US person who owns a single-member US LLC, the IRS treats your company as a foreign-owned disregarded entity, and you must file Form 5472 attached to a pro-forma Form 1120 every year, even if the LLC made no money, and even if it owes no US tax at all. The penalty for missing it is $25,000. The formation platform that sold you the LLC very likely never mentioned this.

This is the spoke of the compliance and filings guide, which covers the whole annual calendar.

Why this exists

Until 2017, a foreign-owned single-member LLC was close to invisible to the IRS. It was disregarded for tax purposes, it had no filing requirement of its own, and the money moving between the owner and the company left no federal trace.

The Treasury closed that in regulations effective for tax years beginning on or after 1 January 2017. Foreign-owned disregarded LLCs are now treated as corporations for this reporting purpose only, which is why you file a corporate form for a company that is not taxed as a corporation. The point is visibility, not tax.

Who has to file

You file if all of these are true:

• The LLC is a US LLC, formed in any state.
• It has one member (or is otherwise disregarded).
• That member is a foreign person: a non-resident individual or a foreign entity.
• There was at least one reportable transaction during the year between you and the LLC.

That last condition is where owners talk themselves out of filing, and it is where they get it wrong. A reportable transaction is not just revenue. Contributing capital counts. Paying the registered agent out of your personal card counts. Taking money out counts. The formation itself counts. A first year with an LLC that “did nothing” almost always contains reportable transactions.

What you actually send

Two things, together:

1. Form 5472, reporting the LLC’s details, your details as the foreign owner, and the reportable transactions for the year.
2. A pro-forma Form 1120, which means a mostly blank corporate return with the top identifying section completed and “Foreign-owned U.S. DE” written across the top. It is a cover sheet, not a tax computation.

You need an EIN to file (see how to get one without an SSN), and the package goes to the IRS by fax or mail. It is not part of any e-file flow you may already use.

Deadlines

The extension is automatic if you file Form 7004 on time, and it extends the filing, not any payment obligation you might have separately. This date and every other one your LLC has (state, FBAR, your home country) are in the US LLC tax calendar, with an ICS per state.

The penalty, precisely

$25,000 per Form 5472, per year. It applies to failing to file, filing late, and filing a form that is substantially incomplete: the last one catches people who file something to be safe and fill it in carelessly.

If the failure continues after the IRS sends notice, an additional $25,000 applies for each 30-day period. There is a reasonable-cause exception, and “the platform that formed my company never told me” is generally not what the IRS means by reasonable cause.

What this is not

Form 5472 is not a tax return and filing it does not mean you owe US tax. Whether you owe anything federally depends on whether your LLC is engaged in a US trade or business and has effectively connected income, a different question entirely, covered in US tax for non-resident owners.

It is also not the only annual obligation. Depending on your state you will have an annual report or franchise tax, your registered agent renews yearly, and your own country of residence has its own view of the profit, which, for most owners, is the part with the real money attached.

Reportable transactions, which is broader than people expect

The part of the form that catches people out is what counts as a transaction between you and the LLC, because the answer is “more than you think.”

The form is concerned with dealings between the entity and its foreign related parties, which, for a single-member LLC, principally means you. That includes movements most owners do not think of as transactions at all.

Money you put in. Capital contributions, loans to the company, paying a company expense from your personal account.

Money you take out. Distributions, repayments, the company paying a personal expense of yours.

The formation costs themselves. If you paid to form the company, that is generally a contribution and it is reportable, which is why a company that “did nothing” in its first year still has something to report.

Non-cash dealings. Transferring an asset in, letting the company use something of yours, services provided between you and it.

The practical consequence is that almost no foreign-owned LLC has a genuinely empty form, and the belief that “nothing happened so there is nothing to file” is exactly the belief that produces the penalty.

The second practical consequence is that this only works if you kept records. Reconstructing a year of movements between a personal account and a company account from bank statements is possible and miserable. Recording them as they happen takes minutes.

Bookkeeping: the requirement behind the requirement

Less discussed than the form and arguably more important.

The rules require the entity to maintain records sufficient to establish the accuracy of what it reports. In plain terms: you have to be able to show your working. A filed form with nothing behind it is not compliance, it is a form.

What that means in practice for a small entity:

A separate account, used separately. The single most valuable habit, and the one most often skipped. Personal spending from the company account destroys the record and undermines the liability separation at the same time.

A record of every movement between you and the company, with a date, an amount and what it was. A spreadsheet is adequate for a simple entity. What is not adequate is a shoebox of statements and a memory.

Retention. Records need to survive long enough to be produced if asked, which is longer than most people keep anything.

Consistency with your other filings. What you report here should not contradict what you tell your own country’s tax authority. Two filings that disagree with each other is a worse position than one filing that is imperfect.

None of this requires an accounting system. It requires a decision, once, to keep the company’s money and your money in separate places and to write down when they move.

What it costs to get done properly

Worth being direct, because the pricing in this category is opaque and the gap between tiers confuses people.

Formation providers generally sell this as part of an upper tier rather than including it in the entry price. Across the market, annual filing packages for a non-resident-owned LLC sit meaningfully above a thousand dollars a year, and that is not a markup: a correctly prepared pro-forma 1120 with a Form 5472 and the underlying records is real professional work.

Two things follow.

Budget for it as a fixed annual cost, alongside the registered agent and the state filing, from the day you form. It is the largest recurring item and the one most often discovered late.

Treat a very cheap offer with care. The form is short and the work is in knowing what belongs on it. A price far below the market usually means a template filled in without anyone examining your actual transactions, which produces a filed form and not much protection.

This is one of the reasons we include year-one compliance in what we build rather than selling it back later. A structure whose owner does not know this obligation exists is not finished.

If you have missed years

It happens more often than the industry admits, usually to people who bought a cheap LLC and were never told. The options are a late filing with a reasonable-cause statement, or in some situations one of the IRS delinquent international information return procedures. Both are worth doing with someone who has done them before, and both are better than another year of silence: the penalty accrues per year, so the cost of waiting compounds.

If your LLC came from a checkout page and you are not sure what has or has not been filed, switching your LLC starts with exactly that audit. Or take the assessment and we will tell you where you stand, including when the answer is that the structure should not exist at all.
