Do I need to fill in Schedule L (balance sheet)?

Only the total assets line (Schedule L, line 15, column (d)). The other balance sheet detail isn't required for pro forma filings.

Can I e-file the pro forma 1120?

No. Foreign-owned disregarded entities are excluded from e-filing for 1120 and 5472. Mail or fax only.

Do I need to attach Form 1125-A or 1125-E?

No. Those schedules are for active C-corporations. Pro forma 1120 for foreign-owned DEs doesn't require them.

Form 5472 + 1120 filing service

Pro Forma Form 1120 — Plain-English Guide

Foreign-owned US single-member LLCs file pro forma Form 1120 as the procedural vehicle for filing Form 5472. "Pro forma" means most of the form stays blank — you only fill in entity identification fields and stamp "Foreign-Owned U.S. DE" at the top. This guide shows exactly what to fill in.

What does 'pro forma' mean here?

Pro forma means "as a matter of form" — you file the form for procedural compliance, not to calculate tax. The IRS requires Form 5472 to be attached to a tax return, but a foreign-owned disregarded LLC isn't subject to US corporate income tax. So the 1120 becomes a near-empty envelope. Don't fill in income, deductions, or tax calculations. Doing so would incorrectly subject your LLC to US corporate tax.

Fields you DO fill in

• Entity name (matching your EIN confirmation letter) • EIN • US address • Date of incorporation • Total assets at year-end (Schedule L, line 15, column (d)) • "Foreign-Owned U.S. DE" stamped or written across the top of page 1

Fields you LEAVE BLANK

• Income section (lines 1-11) • Deductions (lines 12-29) • Tax computation (lines 30-37) • Most schedules (Schedule C, D, J, K, M-1, M-2) Leave them empty. Don't write "0" — write nothing. The IRS instructions specifically say pro forma 1120s for foreign-owned DEs have these sections blank.

The 'Foreign-Owned U.S. DE' stamp

This is a literal requirement from the IRS instructions. At the top of page 1 of Form 1120, write or stamp: "Foreign-Owned U.S. DE" This tells the IRS this is a pro forma filing for Form 5472 purposes, not a real corporate income tax return. Without this stamp, the IRS may try to process it as a regular 1120 and trigger problems.
