Not quite. 1 husband + 1 wife = 2 people = multimember.

I believe in California, a community property state, a husband and wife can choose to ignore the LLC and treat as a joint venture on Schedule E. CA practitioners please weigh in.

In noncommunity property states, once they've mucked it up with an LLC they can't. Unless the ownership is tenants by the entirety. That's one owner. This form of ownership is not available in all states.
