        administrative or judicial action described in paragraph (5) 
        based on information brought to the Secretary's attention by an 
        individual, the Secretary shall, as determined by the 
        Whistleblower Office and subject to paragraph (2), pay such 
        individual as an award at least 15 percent but not more than 30 
        percent of the collected proceeds (including penalties, 
        interest, additions to tax, and additional amounts) resulting 
        from the action (including any related actions) or from any 
        settlement in response to such action. The Whistleblower Office 
        shall determine the amount of such award on the basis of the 
        extent to which the individual substantially contributed to 
        such action.
            ``(2) Award in case of less substantial contribution.--
                    ``(A) In general.--If the Whistleblower Office 
                determines that the action described in paragraph (1)

                allegations (other than information provided by the 
                individual described in paragraph (1)) resulting from a 
                judicial or administrative hearing, from a governmental 
                report, hearing, audit, or investigation, or from the 
                news media, the Whistleblower Office may award such 
                sums as it considers appropriate, but in no case more 
                than 10 percent of the collected proceeds (including 
                penalties, interest, additions to tax, and additional 
                amounts) resulting from the action (including any 
                related actions) or from any settlement in response to 
                such action, taking into account the significance of 
                the individual's information and the role of such 
                individual and any legal representative of such 
                individual in contributing to such action.

                is original source of information.--Subparagraph (A) 
                shall not apply if the information resulting in the 
                initiation of the action described in paragraph (1) was

        planned and initiated the actions that led to the underpayment 
        of tax or actions described in subsection (a)(2), then the 
        Whistleblower Office may appropriately reduce such award. If 
        such individual is convicted of criminal conduct arising from 
        the role described in the preceding sentence, the Whistleblower 
        Office shall deny any award.

        regarding an award under paragraph (1), (2), or (3) may, within 
        30 days of such determination, be appealed to the Tax Court 
        (and the Tax Court shall have jurisdiction with respect to such 
        matter).
