Do I Need to File Form 5472? Take the 3-Minute Quiz

The filing rule rests on two conditions that must both be true. First, a foreign person — a non-resident individual, a foreign corporation, partnership, trust, or estate — must own at least 25% of the US entity, measured by vote or value. Second, the entity must have had a reportable transaction with that foreign owner or another related foreign party during the tax year. Miss either condition and you do not file; meet both and you do.

The single most common filer is the foreign-owned single-member LLC. A non-resident forms a Wyoming, Delaware, or New Mexico LLC, owns 100% of it, and runs e-commerce, consulting, or SaaS through it. Because one foreign person owns all of it, the 25% test is cleared instantly. The requirement has applied to these disregarded entities since tax years beginning on or after January 1, 2017, under Treasury Decision 9796.

A “25% foreign shareholder” is any non-US person who owns 25% or more of the stock or value of the US entity, measured by either total voting power or total value. The threshold is checked at any time during the tax year, so a foreign owner who held 25% for even one day brings the entity inside the rule. Indirect and constructive ownership rules under IRC §318 can pull in shares held through related parties, so structures designed to dilute below 25% rarely work.

The common cases

For a single-member LLC the math is trivial: one owner holds 100%, far above the 25% line. For a C-corporation, count each foreign shareholder individually — a corporation with four unrelated foreign owners at 20% each may still trigger the rule through constructive ownership, while a corporation that is genuinely 90% US-owned with a single 10% foreign holder does not meet the 25% test and does not file. When a foreign person clears 25%, move to the second test.

This is the test that catches almost everyone. People assume Form 5472 applies only to companies that earn a profit. It does not. The trigger is a transaction, not income. The instant you wire money from your personal account to fund your LLC, you have created a reportable transaction — and the filing obligation is locked in for that year.

Because forming and funding an LLC always means moving money from the owner, virtually every foreign-owned single-member LLC has at least one reportable transactionin its first year. That is why the honest answer to “do I need to file?” is, for almost all foreign founders, yes.

A single-member LLC is normally a disregarded entity: the IRS looks straight through it to the owner and ignores the entity for income tax. For most purposes that is still true — the LLC pays no federal income tax of its own. But final regulations under T.D. 9796 carved out an exception: a foreign-owned disregarded entity is treated as a separate domestic corporation for the reporting and record-keeping rules of section 6038A only.

What that means in practice

The keyword “form 5472 disregarded entity” trips up many founders precisely because of this twist: being disregarded for income tax does not exempt you from Form 5472. The LLC must obtain an EIN (using Form SS-4, by fax or mail for a non-resident without an SSN), then file a pro forma Form 1120with Form 5472 stapled behind it. “Pro forma” means a shell return — you complete only the name, address, EIN, and incorporation lines, write “Foreign-owned U.S. DE” across the top, and leave every income and tax line blank. The package is then mailed or faxed as a single unit.

The exemptions are narrow and rarely rescue a founder-owned LLC. The main one is simple: if the entity had zero reportable transactions with any related foreign party for the entire year, there is nothing to report and you do not file. In a first year this almost never happens, because forming and funding the LLC creates a reportable transaction on day one.

Because the exemptions are so limited, the safe default for any foreign-owned single-member LLC is that it must file. If the quiz lands you on “you likely do not need to file,” treat that as a prompt to confirm with us in writing before acting — a wrong assumption carries a $25,000 penalty with no statute of limitations.

Form 5472 carries one of the harshest information-return penalties in the US tax code. The base penalty is $25,000 for each form not filed, filed late, or filed substantially incomplete. Because there is no statute of limitations on an unfiled information return, a year you missed five years ago can still be assessed today. And the penalty compounds: if the IRS sends a notice and the form is still not filed within 90 days, an additional $25,000 applies for each 30-dayperiod the failure continues.

That is why a free 3-minute quiz is worth running before you assume you are off the hook. If you should have filed and did not, the IRS may later assess the penalty; you can request abatement for reasonable cause, but relief is discretionary and never guaranteed. The cheaper path is to file correctly and on time. We prepare Form 5472 plus the pro forma Form 1120, have a specialist review it, and file it the only accepted way for a flat $299 — versus $547 at form5472.online and $1,999/year at doola.

The phrase “reportable transaction” sounds technical, but for a foreign-owned LLC it almost always reduces to a handful of everyday money movements between you and your company. The IRS defines a reportable transaction as any transaction listed in Parts IV, V, and VI of Form 5472 between the reporting entity and a related party. Crucially, the dollar threshold is effectively zero — there is no de minimis exemption for a disregarded entity, so even a $1 movement is reportable and must be disclosed by category.

For a single-member LLC, the related party is almost always you, the foreign owner. The five categories below cover the lifecycle of nearly every founder-funded company: you put money in to start it (contribution), you lend it working capital (loan), the company pays you back (repayment), you pull profit out (distribution), and the company pays you a management or service fee (services). Any single one of these in a tax year locks in the filing obligation — there is no need for all five to occur.

The five core reportable transactions

Notice the first row. The single most common trigger — by a wide margin — is the opening capital contribution. The moment you move money from your personal account to fund the LLC’s new bank account, you have made a reportable transaction, and the filing obligation for that year is set. This is why virtually every foreign-owned single-member LLC has at least one reportable transaction in its very first year, regardless of whether it ever earned a cent of revenue. The completed pro forma Form 1120 with Form 5472 attached then goes by mail to P.O. Box 149342, Austin, TX 78714-9342 or by fax to 855-887-7737 — it cannot be e-filed.

“Dormant” is one of the most misunderstood words in Form 5472. Founders assume that an LLC with no customers, no revenue, and no activity is automatically off the hook. That is wrong. The exemption is not for an inactive business — it is for an entity with zero reportable transactions. Those are two very different bars. An LLC can have no sales whatsoever and still fail the “truly dormant” test the instant a single dollar moves between it and its foreign owner.

The trap is the state fee. Every US LLC owes an annual obligation to its state — a Wyoming annual report ($60), a Delaware franchise tax ($300), or a similar charge elsewhere — plus a registered-agent fee. If you pay any of those from your personalcard or bank account on the company’s behalf, you have funded a company expense, which is a capital contributionand a reportable transaction. That one payment converts an otherwise “dormant” LLC into a mandatory filer.

Dormant vs. truly dormant

In short, a genuinely dormant LLC is rarer than founders think — it requires that no money or property ever crossed between the company and any related foreign party for the whole year, including fees paid on its behalf. Given the $25,000 penalty with no statute of limitations, if there is any doubt, the safe assumption is that you must file. Confirm in writing before relying on the dormant exemption.

Form 5472 is fundamentally a corporate reporting form, so for a multi-member LLC the answer turns entirely on how the IRS taxes the entity — not on the LLC label. By default, a multi-member LLC is taxed as a partnership. A partnership reports its foreign-owner information through a completely different channel: it files Form 1065 and issues a Schedule K-1 to each member, and foreign partners are handled through Forms 8804/8805 withholding rather than Form 5472. A default partnership-taxed LLC therefore generally does not file Form 5472.

The picture flips the moment the LLC elects corporate taxation by filing Form 8832 (or Form 2553 for S-corp status, which most foreign owners cannot use because non-residents are ineligible shareholders). A multi-member LLC taxed as a C-corporation files a real Form 1120, and if a foreign person owns 25% or more of it, it must attach Form 5472 — exactly like any other 25%-foreign-owned corporation under IRC §6038A.

Multi-member LLC routing by tax election

One important nuance: the well-known single-member disregarded-entity rule under T.D. 9796applies only to LLCs with one owner. A partnership-taxed multi-member LLC is not a disregarded entity, so it is not pulled into Form 5472 the way a single-member LLC is. The decisive question for any multi-member LLC is always: how is it taxed? Answer that, and the form follows.

Form 5472 is filed per related party, not per entity. If your LLC transacted with more than one foreign related party during the year — say a foreign owner and a foreign-parent company and a sibling company under common control — you prepare a distinct Form 5472 for each one. A single LLC can therefore file several Forms 5472 in the same year, one documenting the reportable transactions with each related party.

A “related party” under IRC §6038A is broader than just the owner. It includes any 25% foreign shareholder, any person related to that shareholder under the §267(b) and §707(b) attribution rules, and any other party in a §482 controlled relationship with the entity. So payments to a foreign holding company, a foreign affiliate, or a foreign individual related to the owner each need their own form if reportable transactions occurred with them.

How the package is assembled

Despite the multiple forms, you do not file multiple returns. There is still one pro forma Form 1120 for the entity, with every Form 5472 attached behind it, all mailed to P.O. Box 149342, Austin, TX 78714-9342 or faxed to 855-887-7737 as a single submission by April 15 (or October 15 with a timely Form 7004 extension). And remember the penalty is assessed per form: with three related parties, a missed year exposes you to $75,000, not $25,000 — which is exactly why we map every related party before filing, all included in our flat $299.
