Compared with states such as Texas and Florida, Illinois usually leaves you with lower net pay because state income tax applies on top of federal tax and FICA payroll deductions.
$70,000 in Illinois can be a solid salary, but how far it stretches depends on where you live, your household costs, and how much you pay through payroll for benefits or retirement. In lower-cost parts of the state it can go much further than in more expensive metro areas.
That is why after-tax comparisons are useful. Two jobs with the same headline pay can feel very different once state tax, housing costs, and payroll deductions are properly factored in.
