LLC disregarded entity of C-Corp

[jasdlm]

C-Corp is 100% owner of LLC started in 2009. I want to verify that I am thinking about the return correctly. I have never done this. I only found out about the LLC formation when C-Corp owner brought in his usual tax 'bits'.

1) I am putting the income/expenses of both entities on the 1120

2) Both are reporting under the tax ID number of the C-Corp; taxpayer did not obtain a separate tax ID.

3) How do I even reference the LLC? On a sole proprietor/disregarded entity, I would reference it on the top portion of the Schedule C. Do I use Form 851? If so, do I just repeat the C-Corp EIN when it asks for EIN?

Thanks in advance for confirming/answering the above and/or setting me straight.

Why would you need to reference it? It's just a division/department of the C-corp and should be included with other numbers on the 1120. You could prepare a worksheet/attachment to the 1120 showning the separate activity of the LLC, but it is not required and probably not wanted by the IRS. Separate accounting, however, should be reported on financial statements for the company.

Thanks, much, OldJack.
