@mlsowers just to close out this thread -- it is quite a long one.
(a) for a dis-regarded entity , it is so only for tax purposes . Thus the owner files his/her return on Schedule-C using his/her SSN and not EIN.
(b) The business still can use its EIN for collecting employee taxes, depositing them with the taxing authorities and maintaining / operating bank accounts. Thus a payment received from a customer can be addressed to the business and deposited into the business bank account.
(c) The business can/does issue W-2, 1099-NEC, 1099-Misc etc. using the EIN as Employer identity of the business. There is no issue ( I have just tried ) in TurboTax issuing the information returns ( W-2/1099s etc. ) using the EIN.
(d) When the owner of the disregarded entity for tax purposes files his/her own return there is NO conflict between owner's SSN and the business EIN -- Schedule C is based on SSN of the owner, EIN is entered ONLY as in formation of the business..
(e) There is no issue using the EIN of the business for purposes of W-9 -- it allows the use of either SSN or EIN ----- one just has to remember at which level one is operating -- as a person ( SSN ) as a business/ entity (as self-standing like a C-corp , even though it is not treated as such for tax purposes).
I hope this closes this issue.
