35 ILCS 200/18-120
This Sec. applies only to rates which are specifically made subject to increase or decrease according to the referendum provisions of the General Revenue Law of Illinois. The question of establishing a maximum tax rate limit other than that applicable to the next taxes to be extended may be presented to the legal voters of any taxing district by resolution of the corporate authorities of the taxing district at any regular election. Whenever any taxing district establishes a maximum tax rate lower than that otherwise applicable, it shall publish the ordinance or resolution establishing the maximum tax rate in one or more newspapers in the district within 10 days after the maximum tax rate is established. If no newspaper is published in the district, the ordinance or resolution shall be published in a newspaper having general circulation within the district. The publication of the ordinance or resolution shall include a notice of (a) the specific number of voters required to sign a petition requesting that the question of the adoption of the maximum tax rate be submitted to the voters of the district; (b) the time within which the petition must be filed; and (c) the date of the prospective referendum. The district clerk or secretary shall provide a petition form to any individual requesting one.
Either in response to the taxing district's publication or by the voters' own initiative, the question of establishing a maximum tax rate lower than that in effect shall be submitted to the voters of any taxing district at the regular election for officers of the taxing district in accordance with the general election law, but only if the voters have submitted a petition signed by not fewer than 10% of the legal voters in the taxing district. That percentage shall be based on the number of votes cast at the last general election preceding the filing of the petition. The petition shall specify the tax rate to be submitted. The petition shall be filed with the clerk, secretary or other recording officer of the taxing district not more than 10 months nor less than 6 months prior to the election at which the question is to be submitted to the voters, and its validity shall be determined as provided by the general election law. The officer receiving the petition shall certify the question to the proper election officials, who shall submit the question to the voters.
Notice shall be given in the manner provided by the general election law.
