Form 5472 for Foreign-Owned LLCs: the $25,000 Filing You Can't Skip (2026)

Who actually has to file (and why it probably means you)

Start with the bottom line: a U.S. LLC that is 100% owned by a non-U.S. person and treated as a disregarded entity must file Form 5472. If you set up a single-member LLC in Delaware, Wyoming, New Mexico, or anywhere else, you're a foreign individual or foreign company, and you didn't elect to be taxed as a corporation, this is you.

Here's the mechanism. Normally a single-member LLC is a "disregarded entity" — invisible for federal tax, with its activity just flowing onto the owner's return. But under Treasury Regulation §1.6038A-1, for tax years beginning on or after January 1, 2017, a foreign-owned U.S. disregarded entity is treated as a separate corporation for the limited purpose of these reporting rules. That re-classification is what drags your "invisible" LLC into the Form 5472 regime.

The IRS defines a foreign-owned U.S. DE as "a domestic DE that is wholly owned by a foreign person." Note the standard: for a disregarded entity it's 100% foreign ownership that triggers it. (The widely-quoted "25%" threshold is the rule for foreign-owned corporations — a related but separate trigger.) If you and a foreign business partner own a U.S. multi-member LLC taxed as a partnership, different rules apply; this guide is about the single-member, foreign-owned, disregarded-entity case, which is by far the most common for cross-border founders.

Two quick things to confirm about yourself: (1) you're a foreign person — a non-resident alien individual, a foreign corporation, partnership, trust, or estate; and (2) your LLC is a disregarded entity — single-member and you never filed Form 8832 or 2553 to be taxed as a corporation. If both are true, plan to file. Not sure whether an LLC is even the right wrapper for you?

"But I made zero income" — why that doesn't save you

This is the trap that catches the most people, so let's be blunt: having zero income, zero profit, or no U.S. business activity does not exempt you from Form 5472. The filing is triggered by reportable transactions, not by income, and almost every LLC has at least one in its very first year.

Form 5472 is an information return, not a tax return. It doesn't calculate tax you owe (a disregarded entity owned by a non-resident with no U.S.-source income often owes none). It exists so the IRS can see money moving between your LLC and you — its foreign owner. So the question is never "did I make money?" It's "did money move between me and the LLC?"

Did you wire funds into the LLC's bank account to capitalize it? Reportable. Did you pay the state filing fee, the registered agent, or a formation service to create the LLC? Reportable. Did you take money back out? Reportable. Did you lend the LLC money, or have it lend money to you or a sister company? Reportable. For a brand-new LLC with no customers, the act of forming and funding it is itself a reportable transaction — which is precisely why "I didn't do anything this year" is not a defense.

The only realistic way a foreign-owned single-member LLC escapes a filing year is if it genuinely had no reportable transactions of any kind in that year — no contributions, no distributions, no loans, no expenses paid on its behalf. That's rare. When in doubt, file. A pro forma 1120 with a Form 5472 showing modest numbers costs you an hour; missing it costs $25,000.

What counts as a "reportable transaction"

A reportable transaction is essentially any exchange of money or value between your LLC and a related party — and as the 100% owner, you are the related party. The IRS sorts them across three parts of the form:

• Part IV — monetary transactions in the ordinary course: sales, purchases, rents, royalties, interest, commissions, and similar amounts paid or received.
• Part V — transactions specific to disregarded entities: the IRS spells this out as "amounts paid or received in connection with the formation, dissolution, acquisition, and disposition of the entity, including contributions to, and distributions from, the entity." This is the part most non-resident LLC owners use.
• Part VI — non-monetary or less-than-full-consideration transactions: e.g., contributing property instead of cash.

Concretely, for a typical foreign-owned LLC these are the line items to watch:

You report dollar amounts, not line-by-line receipts — but you do need to know your numbers, which is the whole reason you keep clean books and bank records. The IRS can require those records on request, so don't run the LLC out of your personal account and hope to reconstruct it later.

The pro forma Form 1120 cover — and exactly what to fill in

Form 5472 is never filed alone. It rides on top of a tax return. For a foreign-owned disregarded entity, that return is a "pro forma" Form 1120 — "pro forma" meaning you're not actually filing a corporate income tax return, you're using the 1120 as a cover sheet so the 5472 has somewhere to attach.

The good news: you fill out almost none of it. Per the IRS instructions, "the only information required to be completed on Form 1120 is the name and address of the foreign-owned U.S. DE and items B and E on the first page." In practice:

• Name and address: your LLC's legal name and mailing address (U.S. or foreign is fine).
• Item B: your LLC's EIN — this is mandatory. No EIN, no valid filing. If you don't have one, get it first; our free EIN guide walks non-residents through getting one without paying a service.
• Item E: check the box that fits — Initial return for your first filing year, Final return if you're closing the LLC.
• Write "Foreign-owned U.S. DE" across the top of the Form 1120 (and across the top of Form 7004 if you extend).
• Sign and date at the bottom; you can enter "Owner" as your title. Leave every other field — income, deductions, tax — completely blank.

Then complete Form 5472 itself: Part I (the reporting entity — your LLC), Part II (you, the 25%+ / direct foreign owner), Part III (the related party), and the relevant transaction parts (IV/V/VI). Staple or clip Form 5472 behind the pro forma 1120 and you have a complete package.

How and where to file: mail or fax only, never e-file

This surprises people in 2026: a foreign-owned disregarded entity cannot e-file this package. There's no TurboTax button, no online portal. You submit on paper, one of exactly two ways, to a single dedicated IRS unit in Ogden, Utah.

Option 1 — Fax (often fastest): send to 855-887-7737, at 300 DPI or higher. Keep the fax confirmation page; that's your proof of timely filing.

Option 2 — Mail:

Internal Revenue Service
1973 Rulon White Blvd.
M/S 6112, Attn: PIN Unit
Ogden, UT 84201

The IRS is explicit that foreign-owned U.S. DEs must use this special address and "do not use the mailing addresses provided in the Instructions for Form 1120." Sending it to the regular 1120 address is a classic way to have a filing go missing. If you mail, use a method with tracking (certified mail or an IRS-approved private courier) and keep the receipt — your tracking record is how you prove you filed on time if the IRS ever claims it didn't arrive.

Submit the package once: don't both mail and fax the same return, which can create duplicate-filing confusion. Pick one method and retain the proof permanently.

The deadline — and how to extend it

Your LLC takes the same tax year as its owner; for nearly all individuals that's the calendar year. So for the 2025 tax year, the package is due April 15, 2026.

Need more time? File Form 7004 (the automatic extension request) by April 15, and you push the deadline six months to October 15, 2026. Two important notes: (1) Form 7004 must itself be filed by the original April 15 deadline — an extension you file in May is worthless; and (2) write "Foreign-owned U.S. DE" across the top of the 7004 too. Because a disregarded entity with no U.S. tax owed isn't sending a payment, this is a true filing extension with nothing to pay — but the form still has to be in on time.

One more nuance for cross-border owners: if you live outside the U.S., you may benefit from the automatic two-month extension to June 15 that applies to taxpayers abroad, but don't rely on it for Form 5472 without confirming it applies to your situation — the safe, universal move is to file Form 7004 by April 15 and never think about it again.

The penalties: why this is a $25,000 form

Here's what makes Form 5472 unforgiving. The penalty isn't a percentage of tax — there may be no tax at all — it's a flat $25,000 for each return that's not filed, filed late, or "substantially incomplete." The IRS doesn't have to prove you owed money. The penalty attaches to the information failure itself.

And it compounds. Per the instructions: "If the failure continues for more than 90 days after notification by the IRS, an additional penalty of $25,000 will apply" — and that additional penalty applies "for each 30-day period (or part of a 30-day period) during which the failure continues after the 90-day period ends." So a single ignored notice can snowball from $25,000 into six figures.

There's a second, quieter cost most guides skip: the statute of limitations stays open. Under IRC §6501(c)(8), when a required international information return like Form 5472 isn't filed, the clock the IRS runs on to assess any tax for that year generally doesn't start until you file. The normal three-year window can stay open indefinitely on a year you never closed out — meaning a forgotten 5472 keeps that whole tax year auditable for years. Filing isn't just penalty-avoidance; it's how you close the year.

How to actually get it filed: DIY vs. accountant vs. formation service

You have three honest paths, and the right one depends on how comfortable you are with U.S. paperwork.

DIY. For a simple, brand-new LLC with a handful of contributions and fees, the package is genuinely doable yourself — a pro forma 1120 with five boxes filled in, a Form 5472 with your details, faxed to Ogden. The IRS instructions (linked below) are the real source of truth. If your transactions are clean and few, this is a legitimate free option and there's no shame in it.

Accountant / cross-border CPA. If you have real activity — multiple related entities, intercompany loans, property contributions, or you're behind on prior years — pay a CPA or enrolled agent who does international filings. Typical one-off pricing runs from roughly a couple hundred to several hundred dollars per year, which is trivial against a $25,000 penalty. Make sure they actually handle foreign-owned DE filings; not every U.S. accountant does.

Formation service that includes compliance. Several services that set up LLCs for non-residents also handle the annual Form 5472 / pro forma 1120 as part of a compliance plan, so you never touch the IRS yourself. This is the lowest-effort route. We break down which services are genuinely good for non-residents — and which bundle 5472 compliance — on our best LLC service for non-residents comparison. Whatever you choose, confirm in writing that the annual 5472 filing is included; "registered agent" is not the same as "tax compliance."

Before you even get here, make sure your name and brand are clear with our business name search and trademark search tools — sorting that out early saves you from amending an entity later (which is, you guessed it, another reportable event).

Already missed a year? Reasonable-cause relief

If you just discovered you should have filed for a past year — and you haven't gotten an IRS notice yet — don't panic, and don't ignore it. The path forward is to file the delinquent Form 5472 and pro forma 1120 now, with a written reasonable-cause statement attached explaining why it was late.

The law (IRC §6038A) is built for this: if the failure to file "is due to reasonable cause and not to willful neglect," the penalty is not imposed. Reasonable cause is decided case-by-case on all the facts, and the standard is whether you "exercised ordinary business care and prudence" but still couldn't comply. Good-faith reasons that often work: you genuinely didn't know a zero-income disregarded entity had to file (a very common and credible position for first-time non-resident owners), you relied on a professional who got it wrong, or circumstances outside your control intervened.

Practical tips: be specific and honest in the statement, attach it to the late return, and file before the IRS contacts you — voluntary, proactive filing is viewed far more favorably than a response to a notice. If the dollar amounts or number of missed years are significant, get a cross-border CPA or tax attorney to draft the reasonable-cause statement; the framing matters. And remember the §6501(c)(8) angle — filing the late return is also what finally starts the assessment clock and closes those open years.

The one thing not to do is keep skipping it because you're afraid of the past. Each additional missed year is another $25,000 of exposure. Filing — late, with an explanation — is almost always cheaper and safer than silence.
