Illinois state tax: Overview
When you think about states with high taxes, Illinois may not immediately come to mind. However, the Prairie State has one of the highest sales tax rates in the U.S., some of the highest property taxes in the nation, and still taxes groceries, diapers, and prescription drugs — essentials that could be tax-exempt in other states.
But there may be some good to all this "bad" tax news. When you retire, Illinois is one of the states that don't tax retirement income. Plus, there is no state personal property tax, which means you won't pay annual property taxes on your car.
Read on for more of what you need to know as a current or prospective Illinois taxpayer.
