Cook County Treasurer's Office - 9/2/2006
Post-due-date property tax payments can be made at www.cookcountytreasurer.com year-round, 24 hours a day, Cook County Treasurer Maria Pappas says.
Taxpayers whose payments for the second installment of tax year 2005 were not received by the September 1, 2006, due date have the online option to pay immediately out of a checking or savings account, Pappas said.
"Just have your Property Index Number with you, then touch the 'Online Payment' icon on this Home Page and follow the prompts," Pappas said. "This is the fastest and most convenient way to pay."
Pappas urged taxpayers making delinquent payments to do so quickly - state law imposes a penalty of 1.5 percent per month on late payments.
