How do you write a motion to dismiss an old IRS tax debt and include it on my bankruptcy?

If there is a judgment in a court for the IRS debt, you do not need to file a motion to include it in your bankruptcy. If the tax due was determined more than 3 years before the filing date, you include it in your Schedule F.

If you have already filed your bankruptcy documents, you need to file a motion to amend Schedule F with the bankruptcy court. If the case has been closed, you will need to reopen the case, paying the filing fee, and then your motion to add the debt.
