Quick answer: If a foreign person owns a U.S. company, the tax filings are only the visible part of the problem. The harder part is keeping books all year that can actually support those filings — because Form 5472 asks you to report transactions your accounting system may never have been set up to track.

Who this is for

Foreign individuals or companies that own a U.S. LLC or corporation
Single-member U.S. LLCs wholly owned by one foreign person (disregarded entities)
U.S. subsidiaries of foreign parent companies
Foreign companies doing business in the United States
Non-U.S. founders who formed a Delaware, Wyoming or New York entity and now have filing obligations they did not expect

The filing most foreign owners find out about too late

A U.S. LLC wholly owned by one foreign person is normally disregarded for income tax. But under Treasury Regulation §301.7701-2(c)(2)(vi), that same entity is treated as a corporation solely for the reporting rules of Internal Revenue Code §6038A. The practical result: it must obtain an EIN and file Form 5472 attached to a pro forma Form 1120, even though it owes no U.S. income tax and files no ordinary income tax return.

The exposure is not small. Under §6038A(d), failure to file or to maintain the required records carries a penalty of $25,000 per taxable year — raised from $10,000 by the Tax Cuts and Jobs Act. If the failure continues more than 90 days after the IRS notifies you, an additional $25,000 applies for each 30-day period the failure continues, with respect to each related party involved.

A correction worth knowing, because most articles get it wrong

You will read everywhere that a foreign-owned single-member LLC must file Form 5472 every year regardless of activity. That is not what the instructions say. Exception 1 relieves the filing where there were no reportable transactions in Parts IV, V or VI.

The reason it is still true in practice is different, and more useful to understand: for a foreign-owned disregarded entity, Part V sweeps in amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity — including contributions to it and distributions from it. So the year you form the company is a reporting year. Any capital you put in is a reportable transaction. Any money you take out is a reportable transaction. A genuinely zero-transaction year is rare, which is why the shorthand survives.

Knowing why matters, because it tells you what your bookkeeping actually has to capture.

Where the accounting work really is

Form 5472 is a reporting form, not a computation. It asks what moved between the U.S. entity and its foreign owner and related parties. That means the quality of the filing is decided months earlier, by the books.

What the form asks for	What your books must already do
Amounts paid to and received from the foreign owner	Related-party transactions tracked separately, not buried in general ledger accounts
Capital contributions into the entity	Owner contributions distinguished from revenue and from loans
Distributions out of the entity	Distributions distinguished from expense reimbursements and salary
Loans between entity and owner	A real loan account with terms, not a running “due to owner” catch-all
Sales, rents, royalties, interest, commissions	Each category coded to its own account so it can be reported by type

When related-party activity is not separated during the year, someone has to reconstruct it at filing time from bank statements and memory. That is where errors, missed transactions and late filings come from — and the penalty does not care that the mistake was bookkeeping rather than tax.

Effectively connected income: the question behind the question

Foreign owners frequently ask whether they owe U.S. tax at all. The answer usually turns on whether income is effectively connected income (ECI) under IRC §864(c), or fixed, determinable, annual or periodical (FDAP) income.

The distinction is financial, not academic. ECI is taxed on a net basis after allowable deductions, at graduated rates. U.S.-source FDAP that is not effectively connected is taxed at a flat 30%, or a lower treaty rate, on the gross amount — no deductions, no netting — and is generally collected by withholding.

Two businesses with identical cash receipts can therefore face very different U.S. tax outcomes depending on how the activity is structured and documented. We work through this in detail in our guide to effectively connected income for foreign owners.

One thing that trips people up: which entity type actually files

Form 5472 reaches 25% foreign-owned U.S. corporations, foreign corporations engaged in a U.S. trade or business, and U.S. entities wholly owned by one foreign person. A multi-member LLC taxed as a partnership is not a reporting corporation and does not file Form 5472 in its own right.

That does not always end the analysis — a partnership’s transactions can be attributed to a corporate partner that holds 25% or more, and a multi-member LLC that elects corporate treatment on Form 8832 lands back inside the rules. But the blanket claim that “every foreign-owned LLC files a 5472” is wrong, and acting on it can mean filing something you did not need to file.

How we work with foreign-owned U.S. businesses

Year-round bookkeeping structured for the reporting. A chart of accounts that isolates related-party activity, owner contributions, distributions and intercompany loans from day one.
Form 5472 and pro forma Form 1120 preparation. Including the mechanics most people get wrong — these cannot be e-filed by a foreign-owned disregarded entity and go to a dedicated IRS fax number or Ogden address, not the ordinary Form 1120 addresses.
EIN applications for foreign owners without a U.S. taxpayer identification number.
ECI and treaty analysis so you know whether income is taxed net or withheld at gross.
Transfer pricing documentation support where related-party pricing has to be defensible.
Late and missed filings — assessing exposure and reasonable-cause options rather than hoping the year passes quietly.
Monthly financial reporting a foreign parent can actually consolidate and use.

Frequently asked questions

Does my foreign-owned single-member LLC have to file Form 5472 if it did nothing this year?

Possibly not — the instructions provide an exception where there were no reportable transactions. But for a foreign-owned disregarded entity, Part V treats formation, dissolution, capital contributions and distributions as reportable transactions, so most years do involve at least one. Have someone look at the actual activity rather than assuming either way.

What is the penalty for filing Form 5472 late?

$25,000 per taxable year under IRC §6038A(d), plus an additional $25,000 for each 30-day period the failure continues beyond 90 days after IRS notice, applied with respect to each related party. Criminal penalties can also apply in serious cases.

Can Form 5472 be filed electronically?

Not by a foreign-owned U.S. disregarded entity. The IRS instructions state it cannot be e-filed; the pro forma Form 1120 with Form 5472 attached must be faxed or mailed to a dedicated IRS location, with “Foreign-owned U.S. DE” written across the top of the return.

Do I need a U.S. Social Security number to get an EIN for my LLC?

No. A foreign owner without a U.S. taxpayer identification number can still obtain an EIN for the entity. The Form SS-4 instructions specifically address requesting an EIN for the purpose of filing Form 5472 for a foreign-owned U.S. disregarded entity.

We are a foreign company with a U.S. subsidiary. Is this the same thing?

The reporting concept is similar but the mechanics differ. A 25% foreign-owned U.S. corporation files Form 5472 with its regular Form 1120 rather than a pro forma one, and the Part V rules that sweep in contributions and distributions are specific to foreign-owned disregarded entities. The right answer depends on the actual structure.
