Form 5472 for Foreign Holding Companies with US Subsidiaries

A holding structure is just ownership wrapped around a US operating entity. The reporting obligation under IRC §6038A attaches to the US reporting corporation — your US subsidiary — whenever a foreign person or foreign company owns 25% or more of it and there is a reportable transaction with that owner. The foreign holding company itself does not file Form 5472; it is the related party the subsidiary reports on.

Because forming and capitalizing a US subsidiary always moves money from the parent, virtually every foreign-owned US subsidiary has a reportable transaction in year one, so almost all must file. If your subsidiary is a single-member LLC rather than a corporation, the same rules in the foreign-owned single-member LLC guide apply.

The biggest mistake holding-company owners make is assuming the LLC rules apply to a C-corporation subsidiary. They do not. A real C-corporation is a taxpayer: it files a complete Form 1120, reports income and deductions, pays the flat 21% federal corporate rate, and e-files. Form 5472 rides along as an attachment for its intercompany transactions with the foreign parent.

A foreign-owned single-member LLC is a disregarded entity. Since T.D. 9796 took effect for tax years beginning on or after January 1, 2017, it is treated as a corporation solely for Form 5472 reporting. It files a pro forma Form 1120 — name, address, EIN at the top, Form 5472 stapled behind — with no income computation and no tax due. Critically, that disregarded entity cannot e-file: it must mail or fax. Compare the full cost of each path on the pricing page.

Holding structures are dense with intercompany flows, and that is exactly what Form 5472 was written to capture. The parent funds the subsidiary, lends it working capital, charges it management fees, or pulls profits back up — each of those is a separate reportable transaction. Loans and capital movements typically land in Part VI, while services, rent, royalties, and commissions land in Part IV. A foreign-owned disregarded entity uses Part V for its transactions.

Get the categories right, because the IRS reads the dollar totals to flag transfer-pricing risk. If you are unsure which line a transfer belongs on, our Stripe Atlas founders walkthrough covers the same intercompany categories for funded US entities.

There is no consolidated Form 5472 for a group. The obligation lives at the entity level: every US reporting corporation that crosses the 25%-foreign-ownership threshold and has a reportable transaction files independently. A holding company with three US subsidiaries files three Form 5472s, each with its own Form 1120 or pro forma 1120 and its own deadline.

Why the math gets dangerous fast

The deadline is the 15th day of the 4th month after each entity's tax year ends — April 15 for a calendar-year subsidiary. A C-corporation subsidiary uses Form 7004 to extend its real Form 1120 to October 15 and must still pay any 21% tax by April 15 to avoid interest. A disregarded LLC subsidiary has no entity-level tax, so Form 7004 simply extends the pro forma filing to October 15.

In a multi-subsidiary group, each entity tracks its own extension — there is no group extension. For the same deadline rules applied to individual founders, see how digital nomads handle the April 15 date.

The filing channel depends entirely on the entity type of the subsidiary. A real C-corporation files electronically through its tax software like any domestic corporation. A foreign-owned disregarded LLC has no e-file path at all — the only two accepted methods are mail and fax, and the package must be sent by the deadline. Always retain the certified-mail receipt or fax confirmation as proof of timely filing.

One more clarification for 2026: BOI is separate. Under FinCEN's March 2025 interim final rule, US-formed entities — including foreign-owned US LLCs and corporations — are exempt from beneficial ownership reporting; only foreign reporting companies file BOI. Form 5472 is unaffected and still required. To start a filing, use the apply page.

Form 5472 carries one of the harshest information-return penalties in the code, and a holding structure multiplies it across entities. Because there is no statute of limitations on an unfiled information return, a subsidiary's missed year from long ago can still be assessed today. After the IRS mails a notice, failure to file within 90 days adds $25,000 for each additional 30-day period.

We prepare and file the return correctly so it never reaches that stage; we do not provide penalty-abatement or IRS representation. Read the complete rule on the Form 5472 penalty page.

DIY is free but unforgiving, especially across a holding structure where each subsidiary's $25,000 penalty stacks. For a flat $299, form5472.tax prepares the Form 5472 and pro forma Form 1120 for a foreign-owned single-member LLC subsidiary, reviews it, and files it the correct way — by mail or fax, with proof retained. That is $248 less than form5472.online and a fraction of doola's $1,999/year and Firstbase's $999-$1,499/year.
