To insure efficient tax strategies that preempt shocks such as the Cook County 2015 2nd installment property tax bill, owners and tenants must review their property's assessed value and take action through an appeal. To this end, the Cook County Board of Review has opened the following townships for filing with an August 30, 2016 deadline: Barrington; Cicero; Evanston; New Trier; Oak Park; River Forest; Riverside; and, Rogers Park. For properties located in the Collar Counties, be sure to check your local newspapers and County websites for the publication of assessments, e.g., DuPage (http://www.dupageco.org/SOA/1486/) and Lake (http://www.lakecountyil.gov/527/Filing-Deadlines).
