Write "Foreign-Owned U.S. DE" Across Top of Form 1120 — Required Format

Why "Foreign-Owned U.S. DE" Must Be Written Across the Top

Open the current instructions for Form 5472, and the IRS spells out a small but easy-to-miss requirement: foreign-owned U.S. disregarded entities (DEs) must write the phrase "Foreign-owned U.S. DE" across the top of Form 1120 before mailing or faxing it.

This is not optional formatting advice. The IRS routes paper returns inside its Ogden service center based on the contents of the cover page. Form 1120 normally signals a corporate income tax return — full balance sheet, full Schedule M-2, the whole thing. When a foreign-owned single-member LLC files a pro forma 1120 with no income or deductions, the header text is what tells the mail clerk this package belongs to the PIN Unit (foreign-owned DE workflow), not the regular 1120 pipeline.

What Happens If You Skip the Header

Skipping the marking is one of the most common reasons first-time filers receive a CP-notice asking for clarification, or worse, get the return treated as substantially incomplete. The IRS may assume you're filing a real corporate return and start expecting Schedule L, Schedule M-1, and a calculated tax. When the form is empty, the mismatch flags the return for review.

At that point you've already used your filing date, but the IRS isn't done processing — which doesn't actually trigger the $25,000 §6038A penalty by itself, but does start an annoying round-trip of letters and supporting statements that you'd rather avoid.

How to Format the Header Correctly

There are two acceptable ways:

1. Write it by hand in dark ink across the top of the printed Form 1120, above the form's pre-printed title bar.

2. Type it directly into the PDF before printing, using a text annotation tool. Most PDF editors and the IRS's own free fillable forms support this.

In either case the text should be centered, in capital letters where possible (FOREIGN-OWNED U.S. DE), and large enough to be obvious to a human sorter — about 14-point font or larger. There is no exact specification, but the goal is to be unmistakable on a quick visual scan.

Where the Header Sits on the Pro Forma 1120

On the standard Form 1120 the top of the page has the IRS header, the OMB number, and the tax year. The "Foreign-owned U.S. DE" marking goes above all of that, in the white margin at the very top. Don't write over the form's pre-printed text — keep the marking in the margin where it's clearly an annotation, not part of the form itself.

The other reason this matters: faxed returns lose contrast, and a header written in light pencil or with the wrong PDF color will sometimes scan as blank. Use solid black or dark blue.

Does the Header Apply to Form 5472 Itself?

No. The "Foreign-owned U.S. DE" marking is specifically for the pro forma Form 1120 that serves as the cover page. The Form 5472 attached behind it has its own header fields (Part I, Line 1) that identify it as a foreign-owned DE filing, so no additional marking is needed there.

This is also why the Ogden PIN Unit address is different from the standard Form 1120 mailing address: the PIN Unit handles the 5472-with-pro-forma-1120 combination specifically, and the header marking tells them this is one of those packages.
