My check of the Illinois statute -- 205 ILCS 625 -- makes no distinction in who the account owner is, as long as it is a mortal person. I interpret that to mean the owner must be an individual or, if you will, a natural person. There appears to be nothing that would prevent an individual who is a sole proprietor from taking advantage of the "Trustee for" or POD provision (both forms are addressed in the statute).
I was surprised to see that Illinois permits the beneficiary of such an account to be "a natural person who is living, a trust, a corporation, a charitable organization, or any other entity that maintains a lawful existence under the state or federal authority pursuant to which it was organized. Of course, if the beneficiary is not a natural person or charitable organization or other non-profit entity recognized as such under the Internal Revenue Code, it would not be afforded the separate FDIC coverage for revocable trust accounts.
