The answer to the question is "Yes". However, if you sold your
personal primary residence and you lived in and owned the home for at least two
years in the five year period on the date of sale, you do not have to report
the sale if your gains are less than the exclusion amounts of $250,000 if
filing Single or $500,000 if filing Married Filing Jointly (and both lived in
and owned the home for two years).
If your debt was
discharged in a Title 11 bankruptcy proceeding, such as a Chapter 7 or Chapter
13 case, you're not responsible for taxes on that debt. Either way you should receive a 1099-C (Cancellation of Debt). Check with your lender if you should be receiving one for 2016. The debt sometimes is not discharged until a later year. Either way, as you say, it will not be taxable.
However, if the debt, or part of it, was
canceled before you filed bankruptcy (through debt settlement or
negotiation, for example), the creditor must issue the 1099-C and
that debt is not excluded, because it was not discharged in bankruptcy. As
a result, even if you later file bankruptcy, you may owe tax on that debt
cancellation income unless you were insolvent at the time you settled it.
