How Illinois taxes a paycheck
Illinois is a flat-tax state: wage income is taxed at 4.95% regardless of how much you earn. There is no state standard deduction, so the headline rate is close to the real rate from the first dollar of wages.
The signature of a flat tax is visible in the table: the effective state rate barely moves between $40,000 (4.95%) and $150,000 (4.95%), where a progressive state would show a steady climb. All of the progressivity in your total tax bill comes from the federal brackets. At $75,000, an extra $1,000 of salary keeps about $654 after federal, state, and Medicare take their marginal share.
How Illinois compares with other states
On a $75,000 salary, Illinois ranks #44 of 51 among the states and D.C. for take-home pay, $3,713 a year behind the no-income-tax states and $825 behind the median state. The nearest state above it is Minnesota ($101 more per year); just below sits Delaware, $7 behind. Rankings compare state and average local income taxes only — cost of living, housing, and sales taxes move real affordability in ways a paycheck never shows.
