A candidate must return all or a portion of the public subsidy received from the state elections campaign fund or the public subsidy received under section 10A.315, under the circumstances in this section or section 10A.257, subdivision 1.
To the extent that the amount of public subsidy received exceeds the aggregate of: (1) actual expenditures made by the principal campaign committee of the candidate; and (2) approved expenditures made on behalf of the candidate, the treasurer of the candidate's principal campaign committee must return an amount equal to the difference to the board. The cost of postage that was not used during an election cycle and payments that created credit balances at vendors at the close of an election cycle are not considered expenditures for purposes of determining the amount to be returned. Expenditures in excess of the candidate's spending limit do not count in determining aggregate expenditures under this paragraph.
Whether or not a candidate is required under subdivision 1 to return all or a portion of the public subsidy must be determined from the report required to be filed with the board by that candidate by January 31 of the year following an election. An amount required to be returned must be submitted in the form of a check or money order and must accompany the report filed with the board. The board must deposit the check or money order in the state treasury for credit to the general fund. The amount returned must not exceed the amount of public subsidy received by the candidate.
