That may be, but if the court asks for a tax return and you provide an incomplete tax return (by blacking out parts), they're not going to be happy. When you make a decision to file jointly, this may be the consequence. If you really don't want anyone to see the new spouse's information, file separately (yes, you'll pay more in taxes in most cases, but that's not the court's concern).
As I suggested, I would consult an attorney and/or the court clerk before doing this. The last thing you want to do is alienate the judge.
