What Is a Pro Forma Form 1120? Why Yours Is Nearly Blank
Quick answer
A pro forma Form 1120 is a shell. It exists to carry Form 5472 to the IRS, not to report income. For a foreign-owned disregarded entity, four items get completed and the rest of the form stays empty.
What actually gets filled in
"The only information required to be completed on Form 1120 is the name and address of the foreign-owned U.S. DE and items B and E on the first page."
Name. Address. Item B. Item E. Then write "Foreign-owned U.S. DE" across the top of the form.
No income, no deductions, no balance sheet, no schedules. The blankness is correct, and it is the point.
Why it looks wrong and is right
An 1120 is a corporate income tax return. Your LLC is disregarded and does not file a corporate income tax return, so the numbers do not belong on it.
What the IRS needs is a place to attach Form 5472, and the 1120 is that place. The form is acting as an envelope.
Filling it in properly is a real mistake rather than a harmless excess. A pro forma 1120 with income figures reads as a corporate return, which is not what you are, and it invites correspondence about a filing you did not intend to make.
Where it goes
| Detail | |
|---|---|
| Filing method | Paper only. No e-file path exists |
| Fax | 855-887-7737 |
| Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201 | |
| Marked | "Foreign-owned U.S. DE" across the top |
| Due | April 15, extendable to October 15 on Form 7004 |
| Attachment | Form 5472 |
The address is specific to this filing:
"Foreign-owned U.S. DEs are required to use the special mailing address...These filers do not use the mailing addresses provided in the Instructions for Form 1120."
Sending it to the ordinary Form 1120 address is a genuine failure mode, and nothing comes back to tell you.
