At first blush, the state's 4.95% flat income tax rate doesn't seem that steep when compared to other states' top tax rates. And that's true if you're talking about wealthy residents. But for many taxpayers, the income tax rate is on the high end.

Residents of the Land of Lincoln also get no relief when it comes to property taxes. The statewide median property tax rate in Illinois is the second-highest in the nation.

Sales tax rates are high in Illinois, too. The state has the eighth-highest average combined state and local sales tax rate at 8.81%. Illinois also has an estate tax, which can be bad news for your heirs.
