The Pro Forma 1120 Cover: Name, Address, EIN, and the Required Status Items

The practical answer

The cover form in a special reporting packet can look much longer than the information requested for that specific procedure. Keep the prescribed identifying and status fields separate from the ordinary corporate-return sections, and do not fill unfamiliar sections merely to remove blanks. The special pro forma Form 1120 instructions for a foreign-owned U.S. DE require its name and address and items B and E on the first page. Do not automatically expand this into the full income-tax return for an ordinary C corporation.^{[1, p.2] [2, p.1]}

Scope and the records behind the answer

The discussion follows the entity, form and transaction conditions identified below. The same label on a different form can have a different purpose. Keep the relevant entity and reporting period visible while you compare the requirements, and treat each stated exception as part of the rule rather than an optional footnote.

A side-by-side preparation table

Work through the official requirements

Proforma only fields

The special pro forma Form 1120 instructions for a foreign-owned U.S. DE require its name and address and items B and E on the first page. Do not automatically expand this into the full income-tax return for an ordinary C corporation.^{[1, p.2]}

Proforma top mark

Write "Foreign-owned U.S. DE" across the top of the pro forma Form 1120 to identify the special filing package described in the Form 5472 instructions.^{[1, p.2]}

De proforma required

A foreign-owned U.S. DE subject to Form 5472 filing attaches Form 5472 to a pro forma Form 1120 and files by the Form 1120 due date, including a valid extension.^{[1, p.2]}

Field/section Name: Name

Enter the foreign-owned U.S. DE's name.^{[2, p.1] [1, p.2]}

Field/section B: Employer identification number

Enter the DE's EIN.^{[2, p.1] [1, p.2]}

Proforma irm routing

The IRS corporate-return processing manual distinguishes a foreign-owned U.S. DE's pro forma Form 1120 from ordinary Form 1120 income-tax data processing. The DE attaches Form 5472 as required, while the manual says not to process that pro forma as an ordinary Form 1120.^[3]

This applies when: This is internal IRS processing guidance, not cancellation of the pro forma Form 1120/Form 5472 submission obligation or an express signature waiver. Only the January 1, 2026 paragraph in IRM 3.11.16.11(2) is relied on; other paragraphs on the page dated 2027 are not treated as already effective.

Field/section Top annotation: Foreign-owned U.S. DE

Write "Foreign-owned U.S. DE" across the top of the pro forma Form 1120 to identify this special filing.^{[1, p.2]}

Field/section E(4): Address change

Use the applicable item E box when the address changed. This does not replace a separate address-change procedure that is required.^{[2, p.1] [1, p.2]}

Field/section Attachment: Form 5472 attached

Attach Form 5472 for every reportable related party, with the applicable schedules, to the pro forma Form 1120 and submit through the special DE route.^{[1, p.2]}

An illustrative preparation scenario

In this hypothetical preparation example, a preparer opens the full Form 1120 and starts collecting every item shown on the pages. The foreign-owned DE file is first reviewed against the special instructions, identifying the name, address, EIN, and applicable status information while leaving separate signature questions outside an unsupported conclusion. The preparer checks three points: Which fields do the special instructions require? Are identity and status entries supported? Is an ordinary corporate return being confused with the pro forma packet? The file remains a working comparison until the relevant facts and applicable instructions have been checked together. No agency outcome is assumed.^{[1, p.2] [2, p.1]}

This is a planning illustration, not a statement that a particular filing has been accepted or that an entity qualifies for a tax result. Use the source-backed distinctions above to decide what information still needs to be established before a form is completed.

A review sequence you can actually use

1. Which fields do the special instructions require?
2. Are identity and status entries supported?
3. Is an ordinary corporate return being confused with the pro forma packet?

Write down the answer and the record that supports it, rather than marking a question complete because a field contains text. When two records disagree, identify whether the difference concerns the entity, an individual, the reporting period or the type of change. That makes the remaining question specific enough to resolve against the relevant instruction.

Keep the scope of a preparation service separate from the government requirement. A service intake question may gather information for a workflow; it does not create an exception, extend a deadline or determine whether a transaction is reportable. The cited government material remains the basis for those conclusions.
