Summary

A foreign-owned U.S. disregarded entity can have a Form 5472 filing requirement even though it has no income tax return requirement. The first Form 5472 Desk lane is only for a foreign individual who owns 100% of a U.S. single-member LLC treated as disregarded, with clean current-year records and only zero-income or simple owner capital activity.

Foreign-owned U.S. disregarded entities attach Form 5472 to a pro forma Form 1120.

The supported first lane

Use the product only when a foreign individual directly owns 100% of a U.S. single-member LLC, the LLC is clearly disregarded for U.S. income tax purposes, the entity has an EIN, and the year is the current 2025 calendar-year filing.

Why the gate is strict

Form 5472 quickly becomes a professional-review matter when ownership, classification, transactions, treaty claims, U.S. trade or business, ECI, transfer pricing, or IRS correspondence enters the picture.

Where the product stops

Stop for multi-member LLCs, foreign corporate owners, foreign corporations engaged in U.S. business, late filings, IRS notices, missing EIN facts, reasonable-cause strategy, or professional representation.

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.
