Who must file Form 5472
Which companies actually have to file Form 5472.
It isn't about how big your company is or whether it made money — it's about what kind of entity you have and the transactions it makes.
Who counts as a reporting corporation.
Form 5472 is an IRS information return filed by a "reporting corporation" that has reportable transactions with a related party. You can read the form itself on the IRS's About Form 5472 page, and the detailed rules in the Instructions for Form 5472. For a plain-English introduction to what the form is and why it matters, start with our Form 5472 guide.
- 01
A 25%-foreign-owned US corporation
A US corporation is a reporting corporation when at least one foreign person owns, directly or indirectly, 25% or more of its voting power or value at any time during the tax year. If it also has a reportable transaction with a related party, it files.
- 02
A foreign-owned US disregarded entity
A domestic entity wholly owned by one foreign person — a single-member US LLC, for example — is treated as a corporation for the limited purpose of these section 6038A rules, even though it's disregarded for most other tax purposes. When it has a reportable transaction, it follows the IRS's special pro forma Form 1120 filing instructions.
- 03
A foreign corporation doing business in the US
A foreign corporation engaged in a trade or business within the United States is also a reporting corporation, and files when it has reportable transactions with a related party.
"Reportable transactions" is broader than just money changing hands. It covers the transaction types the form lists — sales, rents, royalties, loans, contributions — whether paid in money or, in some cases, made for nonmonetary or less-than-full consideration. There is no minimum dollar amount that automatically exempts you.
The IRS also lists exceptions from filing. A reporting corporation with no reportable transactions of the listed types has nothing to file, and certain foreign corporations — such as those with no permanent establishment under a treaty that file Form 8833, or those whose income is exempt under section 883 — may not have to. The exceptions are specific, so don't assume one applies without checking.
Not every foreign-owned LLC follows the corporation's 25% threshold. That threshold applies to US corporations, and the disregarded-entity rule is a separate, narrower path for entities wholly owned by one foreign person. A US LLC taxed as a partnership with a 25% foreign owner is not automatically a reporting corporation just because of that ownership — your entity's tax classification drives the analysis.
Who this typically catches.
- 01
The solo foreign founder
A single-member LLC or a C-corp you own outright from abroad. A wholly-owned single-member LLC is a foreign-owned US disregarded entity, and a C-corp you own outright is a 25%-foreign-owned US corporation — both are reporting corporations. If you funded the company or it pays you, there are likely reportable transactions too. This is the most common case and the most commonly missed one.
- 02
A foreign-owned entity with intercompany dealings
If your US company transacts with a related foreign company or its foreign owners — royalties, management fees, loans — the transactions are exactly what the form is designed to capture.
- 03
Anyone told by their preparer they don't need it
Not every US accountant knows this form well. If someone waves it off without looking at your ownership and transactions, get a second opinion from a preparer with international experience.
If you think it might apply.
If you recognize yourself in the cases above, the right move is to confirm it with a tax professional who handles foreign-owned US entities — not to guess. Whether you must file depends on your own circumstances, and we are not your accountant.
Once you know it applies, two questions follow naturally: how much it costs to get wrong, and when it's due. We don't publish those numbers — they change and belong on the primary source — but we've written walkthroughs for finding the current answer yourself: the Form 5472 penalty and the Form 5472 due date.

We handle your formation so the entity is correct from day one — and we'll be straight with you about what we don't file.
