”cancelled debt on primary residence“ 只适用于2008-2016金融海啸造成的

跟“primary residence capital gain exclusion” 无关。

“Updated Jan. 5, 2015 — The Mortgage Forgiveness Debt Relief Act of 2007 generally allows taxpayers to exclude income from the discharge of debt on their principal residence. Debt reduced through mortgage restructuring, as well as mortgage debt forgiven in connection with a foreclosure, qualify for this relief.

This provision applies to debt forgiven in calendar years 2007 through 2016. Up to $2 million of forgiven debt is eligible for this exclusion ($1 million if married filing separately). The exclusion doesn’t apply if the discharge is due to services performed for the lender or any other reason not directly related to a decline in the home’s value or the taxpayer’s financial condition.”
