Cook County has mailed out the 2nd installment tax bills for 2010. The 2nd installment is due November 1st.
1st installment tax bills are calculated at 55% of your total tax bill for the prior year. Your actual tax for 2010 is calculated in the 2nd installment, and exemptions are also applied.
If you are not receiving your tax bills in the mail, you may need to change your mailing address. This can be done with the Cook County Treasurer. Visit the website for forms and instructions.
