Answer:
If, in fact, the LLC is eligible to be considered a "disregarded entity" by the IRS, it can use the SSN of one of its members. While I have never seen anything from the IRS that says it recognizes an LLC with more than one member as a disregarded entity, it may be acceptable, since the goal is to get the LLC's income as reported on the member's (or members') tax return, and spouses often file joint returns. I suggest you get a statement from the CPA that the LLC has approval for "disregarded entity" treatment.
