If my loan would be discharged due to TPD, would I have to pay taxes on the discharged loan amount?
If you have showed that you are totally and permanently disabled based on documentation from the SSA or a doctor's certification meaning that you are subject to a three-year postdischarge monitoring period, you are considered to have received the discharge for federal tax purposes a the end of the postdischarge period and that is the federal tax period that you would have to use.
How should I let Nelnet know that I want to apply and request a TPD discharge?
