Form 5472 extension with Form 7004

How Form 7004 fits the foreign-owned U.S. disregarded entity Form 5472 and pro forma Form 1120 path.

By Yann LephayPublished · Last updated

Summary

A foreign-owned U.S. disregarded entity required to file Form 5472 can request an extension by filing Form 7004 by the regular due date. Because Form 5472 is attached to a pro forma Form 1120, the Form 1120 code is used on Form 7004 and the special foreign-owned U.S. DE fax or mail path applies.

Form 7004 must be filed by the regular due date to protect the extension lane.

Extension proof matters

Form 5472 Desk asks whether a timely Form 7004 was already filed. It does not create a retroactive extension or decide whether a late extension can be fixed.

Why the wizard asks for filing date

As of June 10, 2026, a 2025 calendar-year packet is only in the on-time lane if the original deadline was met or a timely Form 7004 extension protects the filing.

Hard stop after missed timing

If the regular due date passed without Form 7004, or the extended due date has passed, the case becomes a late-filing review, not a paid self-preparation packet.

Common questions

Does Form 5472 Desk file with the IRS?

No. It prepares a self-review packet and checklist. The user reviews, signs where required, and files through the official IRS mail or fax path.

Does this product provide tax advice?

No. It is self-help software for a narrow packet-preparation lane. Treaty positions, ECI analysis, transfer pricing, reasonable cause, notices, and representation are outside scope.
