Common questions
Which state leaves you with more take-home pay, Illinois or Indiana?
On a $85,000 single-filer salary, Indiana leaves the most of these 3: an estimated $66,150 a year. The gap across all 3 is $1,585, and that is state income tax alone.
Does this comparison include cost of living?
No. The $1,585 gap here is state income tax on the same salary, before rent, housing, insurance or sales tax. Those routinely reverse the order: a jurisdiction that keeps more of a paycheck is frequently a more expensive place to spend it. Treat this as the tax half of the question.
What salary and filing status is this based on?
A single filer earning $85,000 a year with no dependants and no pre-tax deductions, using 2026 federal, FICA and state rules. A different salary changes the ranking, because states with graduated brackets move relative to flat-rate ones as income rises.
