Penalty, addition to tax, or additional amount
(e) Penalty, addition to tax, or additional amount(1) In general. The term affected item includes any penalty, addition to tax, or additional amount provided by subchapter A of chapter 68 of the Internal Revenue Code of 1986 to the extent provided in this paragraph (e). (2) Penalty, addition to tax, or additional amount without floor. If a penalty, addition to tax, or additional amount that does not contain a floor (that is, a threshold amount of underpayment or understatement necessary before the imposition of the penalty, addition to tax, or additional amount) is imposed on a partner as the result of an adjustment to a partnership item, the term affected item shall include the penalty, addition to tax, or additional amount computed with reference to the portion of the underpayment that is attributable to the partnership item adjustment(s) to which the penalty, addition to tax, or additional amount applies. (3) Penalty, addition to tax, or additional amount containing floor(i) Floor exceeded prior to adjustment. If a partner would have been subject to a penalty, addition to tax, or additional amount that contains a floor in the absence of an adjustment to a partnership item (that is, the partner's understatement or underpayment exceeded the floor even without an adjustment to a partnership item) the term affected item shall include only the portion of the penalty, addition to tax, or additional amount computed with reference to the partnership item (or affected item) adjustments. (ii) Floor not exceeded prior to adjustment. In the case of a penalty, addition to tax, or additional amount that contains a floor, if the taxpayer's understatement or underpayment does not exceed the floor prior to an adjustment to a partnership item but does so after such adjustment, the term affected item shall include the penalty, addition to tax, or additional amount computed with reference to the entire underpayment or understatement to which the penalty, addition to tax, or additional amount applies.
