## Abstract

This document contains temporary regulations (replacing an existing final regulation) defining an omission from gross income for purposes of the six-year minimum period for assessment of tax attributable to partnership items and the six-year period for assessing tax. The temporary regulations resolve a continuing issue as to whether an overstatement of basis in a sold asset results in an omission from gross income. The regulations will affect any taxpayer who overstates basis in a sold asset creating an omission from gross income exceeding twenty-five percent of the income stated in the return. The text of these temporary regulations also serves as the text of the proposed regulations set forth in the notice of proposed rulemaking on this subject in the Proposed Rules section in this issue of the Federal Register.
