Single filer or married filing jointly, standard deduction, wage income only. State brackets are single-filer, so a joint figure in a state that widens its brackets reads high; the federal side is exact for both. Tax credits, itemised deductions and all local income tax are excluded. Full methodology.
Six salaries, single filer, standard deduction, no pre-tax contributions. The FICA column is Social Security and Medicare together, because they come out on the same line of most pay stubs.

The statutory rate is 4.95%, but it applies to taxable income rather than to gross. Illinois subtracts $2,925 first, so a flat rate still produces an effective rate that climbs.

Across the six salaries in the table the Illinois bite runs from 4.59% of gross at $40,000 to 4.88% at $200,000, close enough to flat that the rate is most of the story.
Tax is set once for the whole state. Prices aren't. Illinois scores 100.0 on the federal price index as a whole, and the spread between its cheapest and priciest metro is wider than the gap between most pairs of states. These are the city-level figures on the same salary.
The tax gap between two states is usually the smaller half of the answer. The price gap is the bigger one, and the two pull in opposite directions more often than they'd agree.
