First installment of Cook tax bills due March 1

Updated: March 8, 2012 8:08AM

First installment Cook County property tax bills for tax year 2011 were mailed last week and will be due March 1, according to Hanover Township Assessor Thomas S. Smogolski.

“Property taxes are paid in two installments,” Smogolski said in a press release. “The first installment bill is 55 percent of the total property tax bill for the previous year.”

The release noted that first installment tax bills will not reflect homeowner, senior citizen or other exemptions, nor will they reflect successful assessment appeals that were filed in calendar year 2011.

“The first installment is just an estimate based on what was paid last year,” Smogolski explained. “When the second installment bill is mailed in the fall, it will reflect all exemptions for which the property is eligible as well any savings due to successful 2011 tax appeals.”

Property taxes from one year are due the following year in Illinois.

If money for property taxes is paid into an escrow account with a taxpayer’s mortgage company, the financial institution should receive the tax bill electronically, even if the taxpayer also receives a copy of the bill. Taxpayers with property tax escrows held by their mortgage companies are advised not to pay property taxes on their own. If they do, an overpayment of property taxes may result, the release said.

Property owners who do not have mortgage companies paying their taxes can make tax payments in person, by mail, or on-line at the Cook County Treasurer’s web site, In-person payments are accepted at the Cook County Treasurer’s downtown office at 118 N. Clark St. and at any Chase Bank in the Chicago area.

Although March 1 has long been the due date for first installment tax bills, last year’s due date for first installment taxes was April 1, a one-time occurrence.

That was to give Cook taxpayers a little extra time between when the last installment of 2009 property taxes was due — Dec. 13, 2010 – and when the first installment of 2010 taxes would be due.

The Dec. 13 date was the latest due date ever for property taxes in Cook County. Circumstances are different this year, and as a result the normal due date of March 1 has returned, the release noted.
