Least Tax-Friendly

Illinois’ economic woes are one reason why the Prairie State tops our list of the least tax-friendly states in the country. The state ranks #50 in the latest ranking of states’ fiscal health by the Mercatus Center at George Mason University, and residents are paying the price with higher taxes.

The state's 4.95% flat income tax rate actually isn't that high when compared to other states, but other taxes are a doozy. For example, property taxes in Illinois are the second-highest in the nation. On a $400,000 home in the state, the average annual property tax bill would be an eye-popping $9,634.

Sales taxes are high, too. In some municipalities, combined state and local sales taxes exceed 10%. Most states exempt food and drugs from their sales tax, but that's not the case in Illinois.

Sales Tax

6.25% state levy. Localities can add as much as 4.75%, and the average combined rate is 8.78%, according to the Tax Foundation. Food, prescription drugs and non-prescription drugs are all taxed at 1% by the state, and local tax may be due on these as well.

There is a flat rate of 4.95% of federal adjusted gross income after modifications.
