EIN without business activity
I would like to establish a business checking account and to do so, at least at my bank, they require an EIN. I have submitted the EIN form to the IRS several weeks ago but have received no indication that they have received it. (Not surprising relative to my other dealings with the IRS!!). My question is whether I can just use my SS as the EIN for the purpose of the business checking acct. but still have a business name on the account based on a county DBA or if perhaps that might be based on the bank's policies.
Also, if I do establish an EIN but conduct no business for the time being, but do have deposits and transfers to other business entitites in or from a business checking account is there any expectation that I am engaging in commerce and should be filing a return?
