Our California divorce was final Oct. 3, 2024. We would like to file a joint return for 2024 state and federal tax. We have no dependents. We have always filed joint returns. My ex husband retired 12/21/23 and has no W2 income for 2024. Our income includes Social Security, my pension, and stock dividends that are paid to our family trust. So can we file a joint return for 2024?
