Am preparing to file chapter 7 but cannot find out what to do with IRS debt know it cannot be discharged but should still list it and then try to make arrangements to pay IRS after bankruptcy?

Talk with your bankruptcy attorney. Also, make an appointment with a councelor at your local IRS Field Office. Take all information you have received to date from IRS. It is much better to talk to a local agent face-to-face than try to deal with IRS over the phone. Yes, list it. Even if it cannot be discharged, you still want it listed so that the IRS is given notice that you have entered bankruptcy. I would NOT recommend telling the IRS you are going into bankruptcy. If they know you are about to go into bankruptcy, they will file a tax lien (and if you don't already have one, then you don't want one). The court will notify them once you have filed your petition as long as you list them as a creditor.
