## Abstract

This document contains final regulations that provide guidance on the manner in which an S corporation reduces its tax attributes under section 108(b) for taxable years in which the S corporation has discharge of indebtedness income that is excluded from gross income under section 108(a). In particular, the regulations address situations in which the aggregate amount of the shareholders' disallowed section 1366(d) losses and deductions that are treated as a net operating loss tax attribute of the S corporation exceeds the amount of the S corporation's excluded discharge of indebtedness income. The regulations affect S corporations and their shareholders.
