Lucy and Ricky Ricardo live in Los Angeles, California. After they were married, they started a business named ILL Corporation (a C corporation). For state law purposes, the shares of stock in ILL Corp. are listed under Ricky's name only. Ricky signed the Form 2553 electing to have ILL taxed as an S corporation for federal income tax purposes, but Lucy did not sign. Given that California is a community property state, is the S election for ILL Corp. valid?
