If your first installment of your 2009 property taxes seems higher than last year, it probably is. The Illinois Legislature passed a law ordering that all 1st Installment tax bills be calculated at 55 percent of the prior year’s total property tax obligation. This is a change from previous 1st Installment bills when the calculation rate was 50 percent . The 2009 First Installment due date will be Tuesday, March 2, 2010.
