Peoria County taxpayers are required to pay the second installment of their property taxes this week. The Peoria County Treasurer’s office says payments are due Wednesday. They can be paid at most county banks and the city and county treasurer’s offices by mail, credit card, or electronic check. Payments made by mail must be postmarked by on or before Wednesday. More payment information is available by contacting the County treasurer’s office. Anyone with questions regarding address changes, property assessments, and exemptions should contact the Supervisor of Assessments office.
