Effective tax rate in Illinois
Your marginal bracket is not what you pay. At $70,000 of salary in Illinois the total federal + FICA + state burden works out to about 22.0% — an effective rate well below the top bracket you technically touch.
Raising income moves the effective rate slowly, because the lower brackets and the $16,100 federal standard deduction keep applying. At $120,000 the effective rate in Illinois is roughly 27.2%.
What Illinois take-home pay buys
Cost of living in Illinois sits 7% below the national average (index 93), median household income is $80,306, and a one-bedroom apartment in Chicago rents for roughly $1,950 a month.
A common rule is spending no more than 30% of net pay on housing. Against $1,950 rent in Chicago, that implies monthly take-home of at least $6,500 — roughly a $105,000 gross salary in Illinois.
Cutting your Illinois tax bill legally
Pre-tax contributions are the main lever: 401(k) deferrals, HSA contributions, FSA, and commuter benefits all shrink both federal and Illinois taxable income while FICA still applies to the full wage.
Illinois is one of about a dozen states with a flat income tax — every worker pays the same 4.95% rate regardless of income level.
Local and payroll taxes Illinois adds on top
Illinois adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Illinois has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Payroll systems apply these local layers automatically, so check a real Illinois pay stub against the estimate above: a missing local tax line is the usual reason a paycheck comes in lower than a state-only calculator suggests.
Working across a state line from Illinois
Illinois holds income-tax reciprocity agreements with Iowa, Kentucky, Michigan and Wisconsin. If you commute between them, your wages are taxed only by your state of residence — file the exemption certificate with your employer so the wrong state is not withheld from every paycheck.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Chicago resident spending part of the year at a client site in Indiana may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Illinois tax bill
Illinois charges a 6.25% state sales tax, homeowners pay an average effective property tax of 2.07% of market value, and the minimum wage in force during 2026 is $15.00 an hour.
Chicago's combined rate reaches 10.25%, among the highest in the country.
Income tax is only one part of a state's take. Illinois recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Illinois does not tax retirement income at all — Social Security, pensions, 401(k) and IRA withdrawals are exempt from the flat tax.
Illinois vs Indiana on the same salary
On a $75,000 salary, a single filer keeps about $57,880 a year in Illinois against roughly $59,343 in Indiana — a difference of $1,463, or $122 a month.
Effective combined rates are 22.8% in Illinois and 20.9% in Indiana. Set that gap against living costs: index 93 here versus 90 there, with property tax at 2.07% and 0.84% respectively.
