@ReneeM7122 Are you sure? Because other people have told me that I can attach form W-7 to my CA tax return, and when I contacted the Franchise Tax Board, they also told me I only needed to write "ITIN APPLIED FOR" in the boxes where they ask for my wife's SSN. Also, on the FTB website, it says that CA has an automatic extension until October so I would not need to apply for an extension even if I miss the filing deadline.
