Sec. 10.02. PICKUP OF FIREFIGHTER CONTRIBUTIONS. A municipality to which this Act applies shall pick up the firefighter contributions to the fund that are required or authorized pursuant to Section 10.01 of this Act, whichever is higher. Firefighter contributions will be picked up by a reduction in the monetary compensation of the firefighters. Contributions picked up shall be treated as employer contributions in accordance with Section 414(h)(2) of the Internal Revenue Code for the purpose of determining tax treatment of the amounts under that code. These contributions will be deposited to the credit of the individual accounts of the firefighters in the fund and shall be treated as the monthly contributions of the firefighters for all purposes of this Act. These contributions are not includable in the gross income of a firefighter until the time that they are distributed or made available to the firefighter or survivors of the firefighter. The board of trustees may at any time, by majority vote, discontinue the pickup of firefighter contributions by the municipality.
