Note: The individual income tax rate decreased on January 1, 2015 to 3.75%. The IL-700-T, Illinois Withholding Tax Tables for 2015, is now available on our website at http://tax.illinois.gov/Publications/OtherPub.htm, which enables employers to determine how much tax to withhold from employee paychecks under the new rate.
