I would black out your SSN and anybody else's on the return as well. It is possible for a copy of the return to get into your file and in many states those case files are public record.
I don't know what state you are in but in my state the new spouses income is used to identify what tax bracket you are in, which effects how much money you have available after taxes for support. So there may be a reason to allow the court to know what your spouse makes.
