The income tax rates in Illinois vary depending on your filing status and income level. For individuals, the current rates range from 4.95% to 7.99%. Married couples who file jointly, as well as heads of households, have different brackets with rates ranging from 4.95% to 7.85%. The Illinois income tax is a flat tax, meaning that everyone within a specific bracket pays the same percentage of their income. It's important to note that this is in addition to federal income taxes that must also be paid. Illinois residents must file their state income tax returns each year by the due date, which is typically April 15th.
