1120S Form 7004 PDF Attachment for EF

After 44 years I've never had to attach a file to a 7004. Out of curiosity what and why are you attaching?

As I said in my post....Line 3

I still have no clue why you're attaching a pdf to a 7004. I never have and i've filed thousands of 7004's in my career. A Google AI search reveals:

• Consolidated Returns (Line 3): If a corporation is the common parent of a consolidated group, you must attach a statement listing the name, address, and EIN of each member of the group.
• Short Tax Year (Line 5b): If you are requesting an extension for a short tax year and none of the predefined reasons apply, you must check the "Other" box and attach a statement explaining the reason.
• Net Operating Loss (NOL): If you are reducing the amount of estimated tax to be deposited due to an expected Net Operating Loss (NOL) carryback, you must attach Form 1138, Extension of Time for Payment of Taxes by a Corporation Expecting a Net Operating Loss Carryback.

You answered your own question.

• Consolidated Returns (Line 3): If a corporation is the common parent of a consolidated group, you must attach a statement listing the name, address, and EIN of each member of the group.

Out of your thousands of 7004's you've filed.....have you ever had a consoldiated return with "affiliates?"  If you have, I guess you did them incorrectly.   If not, then you've never had to read the instructions for line 3.
