Form 5472 PDF: Download the 2026 Version and Instructions

There is exactly one authoritative source for the Form 5472 PDF: the IRS.govwebsite. Type “Form 5472” into the IRS search box and you land on the form's information page, which links the fillable form PDF and the “Instructions for Form 5472” PDF side by side. Both downloads are completely free — the IRS does not, and never will, charge to obtain a tax form.

Be skeptical of any other origin. Search results routinely surface third-party sites that either charge a fee for “the official form” or host a stale copy from a prior year. Both are traps. The safe rule is to confirm the address bar reads irs.gov before you download, print, or fill anything.

The IRS splits almost every form into two documents: the form you complete, and a separate instruction booklet that explains it. For Form 5472 this matters more than usual, because the form is dense and the instructions carry information that is impossible to guess from the form alone.

The instructions PDF is where the IRS defines a reportable transaction, lists the two-letter country and three-letter currency codes, explains the mailing and fax rules specific to a foreign-owned disregarded entity, and states plainly that there is no electronic filing for that package. Reading the form without the instructions is the single most common cause of an incorrect return.

For a full line-by-line walkthrough of the booklet, see the Form 5472 instructions guide, and for a worked specimen with sample numbers, the Form 5472 example shows a completed filing.

Filing the current revision is not a formality you can skip. The IRS prints a revision date in the top-left corner of the form, and each revision can renumber lines, add a part, or change how a transaction is categorized. The version in force for the 2025 tax year is the December 2025 revision.

Submitting an old revision risks having the IRS treat the return as substantially incomplete. Under IRC §6038A, a substantially incomplete Form 5472 is the same as not filing at all — which means the full $25,000 penalty applies even though you mailed something in.

The Form 5472 PDF on IRS.gov is fillable: open it in Adobe Acrobat Reader (free) and type directly into each field on screen. This is cleaner and more legible than printing a blank form and writing by hand, and it lets you save a digital copy for your records.

One critical caveat: a fillable PDF is not the same as e-filing. Completing the PDF on a computer does not create an electronic submission. A foreign-owned disregarded entity has no e-file path for this package. You print the completed PDF, attach it to the pro forma 1120, and submit by mail or fax.

What you complete and what you leave blank

On the fillable PDF, a typical single-owner LLC completes Parts I, II, III, V, and VI only. Parts VIII and IX cover cost-sharing and §59A base-erosion payments that apply to large multinationals, not a founder-owned LLC, and stay blank.

For most non-residents with a US LLC, the PDF takes minutes once the bank records are in front of you: identify yourself as the foreign owner, identify the LLC, and list the money that moved between you.

Many foreign owners have no US tax identification number, and the Form 5472 PDF accounts for this with a reference ID number field. When a foreign shareholder or related party lacks a US EIN or SSN, you assign your own alphanumeric reference ID and enter it on the form. The IRS uses it to track that party across filings.

The reference ID must stay consistent year to year for the same party. Changing it between filings can make the IRS treat the parties as different entities. A full explanation of the format and rules lives in the Form 5472 reference ID number guide.

The most common reason founders fill out the Form 5472 PDF wrong is misunderstanding the trigger. The form is required by a transaction, not by profit. The moment you wire money from your personal account to fund the LLC, you have created a reportable transaction — even if the LLC never earned a dollar.

Because forming and funding an LLC always moves money from the owner, virtually every foreign-owned single-member LLC has at least one reportable transaction. The complete catalog is in the reportable transaction guide.

The Form 5472 PDF is only half the package. The regulations require Form 5472 to be attached to an income-tax return, and the only return available to a disregarded entity is a pro forma Form 1120— a separate PDF on the IRS Form 1120 page. “Pro forma” means a shell: a cover sheet, not a real tax computation.

You complete the entity identification block at the top of page 1 — the LLC's legal name, US address, EIN, and formation date — and write “Foreign-owned U.S. DE” across the top margin. Every income, deduction, and tax line stays blank, because a disregarded entity pays no entity-level federal income tax.

The full mechanics, with the exact lines to fill, are in the pro forma 1120 guide and the combined Form 5472 and pro forma 1120 walkthrough.

This is the most misunderstood point about the Form 5472 PDF: there is no e-file path for a foreign-owned disregarded entity. Tax software that e-files normal corporate 1120 returns will not transmit this package. The only two accepted methods are mail and fax.

Because timely filing is the only defense against the $25,000 penalty, keep dated proof of submission. The dedicated Form 5472 fax number guide covers how to fax the package and confirm receipt.

The extension only moves the filing deadline. For a disregarded entity there is no entity-level tax to pay, so there is nothing else to extend — file Form 7004 by April 15 to claim the six-month extension to October 15.

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 — and an outdated revision or missing pro forma 1120 can make the return incomplete. Because there is no statute of limitations, a year you missed long ago can still be assessed.

The penalty also 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-day period the failure continues. The math is laid out in the Form 5472 penalty guide and the penalty calculator.

Most penalties do not come from fraud. They come from simple, avoidable PDF errors by founders who did not know the rules. The five below cause the overwhelming majority of problems.

Each is preventable. A specialist who files Form 5472 every day catches all five automatically — the core reason founders pay $299 rather than risk $25,000 on a DIY attempt.

DIY is genuinely free: the PDFs cost nothing. But the downside is enormous and one-sided. A single mistake — an old revision, a missing pro forma 1120, a misfiled part, a missed deadline — triggers the full $25,000 penalty, even on an honest error.

For a flat $299, form5472.tax pulls the current-revision PDF and instructions directly from the IRS, prepares the form and pro forma 1120, reviews it, and files it correctly — saving $248 versus form5472.online and up to $1,700 versus doola. The full how to file Form 5472 guide walks through every step.

The official Form 5472 carries the title “Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business.” It is published on the IRS.gov Form 5472 page as a free PDF, with the instructions linked as a separate free PDF beside it.

The form exists under Internal Revenue Code §6038A, and foreign-owned single-member LLCs were pulled into it by final regulations effective for tax years beginning on or after January 1, 2017 (Treasury Decision 9796). The IRS Form 5472 overview covers the authority and the official form in full, and the Form 5472 example shows a completed specimen so you can see what a correct PDF looks like before you file your own.

A surprising number of incomplete Form 5472 filings trace back to the wrong PDF viewer. The IRS form is an XFA/AcroForm fillable PDF, and not every program renders its fields. If you open it inside a browser tab, type into the fields, and print straight from the browser, some viewers discard what you typed — the IRS then receives a form that looks blank or only partly filled, which can be treated as substantially incomplete.

The safe routine is simple: right-click the link on IRS.gov, save the PDF to disk, open it in the free Adobe Acrobat Reader desktop application, complete the fields, save a copy, and only then print. Print to actual paper (or to a flattened PDF) so the entered values are baked into the document before you mail or fax it.

If you would rather not wrestle with PDF software at all, a specialist prepares the form on the current revision and hands you a clean, flattened copy for your records as part of the flat $299 filing.

Founders who only learn about Form 5472 after operating for a year or two often must file multiple back years at once. Each back year must use the form revision that was in force for that year — you do not file 2022 on the December 2025 form. The IRS keeps every historical revision on its Prior Year Productspage; search “5472” there and download the correct year's form and instructions.

Because the $25,000 penalty applies per form, per year, with no statute of limitations, three missed years is up to $75,000 of exposure — and using the wrong-year PDF can void a catch-up attempt. The catch-up filing and missed Form 5472 guides walk through filing several back years correctly.

A two-minute review before submission prevents the errors that cost $25,000. Run the completed Form 5472 PDF and its pro forma 1120 cover sheet against the checklist below; every box should be ticked before the package leaves your hands by mail or fax.

The single most overlooked item is proof of filing. Because timely submission is the only defense against the penalty, mail by certified mail or keep the fax confirmation — the Form 5472 deadline guide explains how the postmark and fax date establish timeliness.

Treat the instruction booklet as part of the form, not a footnote. The Form 5472 PDF gives you boxes; the Instructions for Form 5472 PDF tells you what to put in them. Skipping it is the fastest way to file a technically complete but substantively wrong return — the kind that still draws a $25,000 penalty.

The instructions also confirm the authority for the whole regime — IRC §6038A — and the rule that a substantially incomplete form is treated as no filing. The IRC §6038A guide explains that statute, and the Form 5472 instructions guide translates the full booklet line by line.
