Form 5472 pro forma Form 1120 checklist

What the pro forma Form 1120 cover sheet means for a foreign-owned U.S. disregarded entity filing Form 5472.

By Yann LephayPublished 2026-06-10 · Last updated 2026-06-19

Summary

For a foreign-owned U.S. disregarded entity, the IRS instructions say Form 5472 is attached to a pro forma Form 1120. The pro forma cover is not a normal corporate income tax return for this lane; the instructions limit the required Form 1120 information to the entity name, address, and items B and E on the first page.

The pro forma Form 1120 cover is part of the official Form 5472 filing path.

What the cover sheet does

The pro forma Form 1120 gives the IRS a filing cover for the attached Form 5472. It does not turn this product into a corporate income tax preparation service.

Required source records

Use the exact LLC legal name, EIN, mailing address, formation records, tax-year facts, owner identity, and related-party transaction records.

When to stop

Stop if the entity may owe a U.S. income tax return, has ECI or U.S. trade/business questions, has classification uncertainty, or needs a corporate tax return beyond the pro forma cover.

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.
