What can I do if my income taxes were discharged in bankruptcy, but my IRS transcript shows that I still owe them?

This is one of the most common mistakes that the IRS computers make.  Their systems (and their agents for that matter) rarely understand discharge of income taxes.  For that reason, the IRS may be wrong about the amount you owe and still try to aggressively collect from you anyway.  If the IRS won't listen, call a tax professional immediately.  There may be an appeal that can be done or your representative may need to get the Taxpayer's Advocate Office (TAO) involved.
