One county bill carries the taxes of every local district, including schools, townships, road and bridge, fire, library and ambulance districts. The Treasurer prepares and collects the bill but has no say over assessments; questions about values and exemptions go to the Supervisor of Assessments, and questions about tax levies and delinquent taxes to the County Clerk. The Treasurer's tax bill page still describes last year's bills, so check your bill or the county's online tax lookup for this year's dates. Card payments carry a 2.25% fee ($2.00 minimum) and e-checks a flat $2.00. Mailed payments go to the Treasurer at P.O. Box 248, Carthage. A Board of Review decision can be taken to the Illinois Property Tax Appeal Board.
