Client received 1099-C for home foreclosed in 2011. Amount of debt discharged includes $103,000 of INTEREST! Is my client taxed on the interest portion!?! Also, is there a statute of limitations for bank to issue 1099-C? 

It was his main home. He does not have an agreement in writing dated before 2018. In 2011 he was insolvent, but not in 2018. Would hate to tell client he has large tax liability because of accrued interest he thought was already dismissed.
