Would I just file normally? Or would I have to file an innocent or injured spouse form?
Most of the deductions comes from the spouse not in bankruptcy.
You need to speak with an attorney in your jurisdiction. Presumptively, you would only get 50%, but you may be able to file an injured spouse return and get the percentage that you actually paid.
This is a question that may be a matter of local practice. You'll want to consult a bankruptcy attorney in your geographic area.
Where I practice, in Detroit, a non-filing spouse filing a tax return jointly with a filing Chapter 13 debtor will be allowed to retain their 50% of the joint refund.
But mileage may differ in your part of Missouri.
