Form 5472 Extension: How to Get More Time (Form 7004)

Last updated: September 11, 2026

Yes — you can extend the Form 5472 deadline by filing Form 7004 by the original due date (April 15 for calendar-year filers), which moves your filing deadline to October 15. Because your Form 5472 attaches to a pro forma Form 1120, you enter the Form 1120 code on Form 7004, write "Foreign-owned U.S. DE" across the top, and fax or mail it — a foreign-owned disregarded entity cannot e-file. An extension gives you more time to file; it does not remove the obligation, and a missed or incomplete Form 5472 can trigger the $25,000 penalty under IRC §6038A(d). It also can't help once April 15 has passed.

Form 7004 is the IRS's "Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns." For a foreign-owned U.S. disregarded LLC, it extends the deadline for the pro forma Form 1120 that Form 5472 is attached to when properly and timely filed. The April 15 and October 15 dates below refer to the 2025 calendar tax year filed in 2026, absent special relief. Other years may shift for weekends or legal holidays. Starting an intake is not the same as filing the return.

Can you get an extension for Form 5472?

Yes. A foreign-owned US disregarded entity that is required to file Form 5472 can request an extension of time to file by submitting Form 7004 by the return's regular due date (IRS, Instructions for Form 5472). The Form 7004 instructions describe the conditions for a valid automatic extension, generally six months, and say the IRS no longer sends approval notifications. See who must file Form 5472 to confirm the filing applies to you.

For a calendar-year filer, that timeline is:

April 15, 2026 — original deadline to file Form 5472 + pro forma Form 1120 for the 2025 tax year (and the deadline to file Form 7004 for an extension).
October 15, 2026 — extended deadline, if Form 7004 was filed on time.

One critical limit: Form 7004 must be filed by the original due date. If April 15 has already passed and you did not file an extension, you cannot extend after the fact — you are now filing late, which is a different process (covered below).

If you are comparing an original deadline with an extended one, the Form 5472 deadline calculator is a quick way to confirm the date before you rely on Form 7004.

How do you file a Form 5472 extension step by step?

A foreign-owned US disregarded entity files the extension a specific way, and getting it wrong means it isn't accepted. Start from the official IRS Form 7004 and follow these steps:

Complete Form 7004 and enter the Form 1120 code on Part I, line 1 — the code for the return your Form 5472 attaches to.
Write "Foreign-owned U.S. DE" across the top of Form 7004, exactly as you do on the return itself.
Fax it to the IRS at +1-855-887-7737 (the IRS Ogden PIN Unit fax) or mail it to the address in the Form 5472 instructions. A foreign-owned U.S. DE cannot e-file Form 7004.
Send it by the regular due date — April 15, 2026 for the 2025 calendar tax year, absent special relief. Do not assume a failed fax attempt satisfies the deadline.
Keep the submitted extension and delivery evidence. A provider's successful transmission report is not an IRS acceptance notice. October 15, 2026 applies only if the extension is valid and timely.

If the EIN is unresolved, see EIN pending at the Form 5472 deadline. An EIN application is not an extension; general “Applied For” return guidance does not guarantee Form 7004 validity. The receipt-confirmation guide explains the limits of transmission evidence.

The instruction that trips people up is the code: because the disregarded entity itself doesn't file an 1120, filers assume there's no code to enter. The IRS is explicit that the Form 1120 code goes on Form 7004, Part I, line 1.

What does a Form 5472 extension actually do?

An extension is narrower than most people think. It buys time to file — nothing more. Here is what it does and does not do:

The extension…	Reality
Extends time to file the return	✓ Yes — six months, to October 15 for calendar-year filers
Extends time to pay tax	No. Separately assess any owner-level or other tax liability and payment deadline.
Removes an existing $25,000 penalty	No. A valid extension changes the filing due date; it does not grant penalty relief.
Helps if you already missed the regular due date	A later Form 7004 does not retroactively extend that deadline; assess late-filing procedures.

The penalty exists to punish not filing, not filing later within an approved window. Under IRC § 6038A(d), the IRS assesses $25,000 on any reporting corporation that fails to file Form 5472 when due (including extensions) or files a substantially incomplete one (IRS, Instructions for Form 5472). An extension moves the "when due" date; it does not weaken the penalty if you still don't file.

Already missed the April 15 deadline?

If April 15 has passed and you didn't file Form 7004, an extension is off the table — but you are not stuck. The IRS provides the Delinquent International Information Return Submission Procedure (DIIRSP) for exactly this situation. You file the delinquent Form 5472 + pro forma 1120 with a reasonable cause statement explaining why it was late, and request that the penalty be abated.

The IRS delinquent international information return procedures warn that penalties may be assessed, including when a reasonable-cause statement is attached. There is no published success rate supporting a promise that most first-time cases avoid penalties. Review the facts with a qualified tax professional and see our guide for late or never-filed returns.

Prepare the return while there is time

An intake may be quick, but gathering records, resolving questions, reviewing the package and transmitting it take additional time. Reconcile owner transactions and retain supporting records. Choose between a timely extension and completing the return based on what can actually be finished by the deadline.

Form5472 Prep generates the complete package (cover letter, pro forma Form 1120, Form 5472, Part V supporting statement, and a reasonable-cause statement if you're already late), an accountant reviews it, and we fax it to the IRS Ogden PIN Unit with a timestamped provider transmission record. Pricing is $149 Standard (ready in 5-7 business days) or $199 Express (ready within 3 business days) — the filing, the accountant review and the package are identical, only the speed differs — with fax delivery included on both and +$99 per additional past year for DIIRSP catch-up.

Frequently asked questions

Can a foreign-owned LLC file a Form 5472 extension?

Yes. A foreign-owned US disregarded entity requests an extension by filing Form 7004 by the return's original due date, entering the Form 1120 code on Part I, line 1, and writing "Foreign-owned U.S. DE" across the top. It extends the filing deadline to October 15 for calendar-year filers.

Can I e-file Form 7004 for a foreign-owned disregarded entity?

No. A foreign-owned U.S. DE cannot e-file Form 7004. The IRS requires you to fax it to +1-855-887-7737 or mail it to the address in the Form 5472 instructions, by the regular due date of the return.

When is the Form 5472 extension deadline?

For a calendar-year filer, Form 7004 must be filed by April 15. If filed on time, it extends the Form 5472 + pro forma 1120 deadline to October 15 of the same year.

Does a Form 5472 extension avoid the $25,000 penalty?

No. An extension only extends the time to file. The $25,000 penalty under IRC § 6038A applies if you fail to file a complete Form 5472 by the due date, including any approved extension. Only filing the return avoids the penalty.

What if I already missed the Form 5472 deadline?

A late Form 7004 does not retroactively extend the deadline. Assess the delinquent return and any reasonable-cause explanation with a qualified tax professional. Penalties may still be assessed; relief depends on the facts and IRS review.

The bottom line

For the 2025 calendar tax year, a valid Form 7004 filed by April 15, 2026 generally extends the filing deadline to October 15, 2026. Follow the dedicated foreign-owned-DE route, preserve the package and transmission evidence, and allow time for preparation and review. Do not confuse an intake, EIN application or fax report with IRS acceptance.
