Average Salary in Illinois

What Illinois workers actually earn — mean and median wages, how Chicago compares with downstate, which occupations pay most, and what any of those figures are worth after the 4.95% state tax and federal withholding.

Why every source gives a different number

Search for the average salary in Illinois and you will find figures from $56,000 to $86,000, all of them defensible. They measure different things, and knowing which is which matters more than picking a favorite.

Mean versus median is the other trap. A handful of very high earners drags a mean upward; the median is the midpoint, where half earn more and half earn less. For "am I paid fairly", the median of your occupation in your metro is the number worth finding. For "how large is the Illinois economy", the mean is more useful.

Chicago, the collar counties and downstate

Illinois is not one labor market. The Chicago metropolitan area accounts for roughly two-thirds of state employment and nearly all of the wage premium over the national average.

The practical consequence for anyone weighing a move within the state: a Chicago salary carries a real premium, but the cost-of-living difference — housing above all — usually eats more of it than the wage gap gives back. Because Illinois has no local income tax, the tax side of the comparison is identical wherever you live in the state.

What the average salary is worth after tax

Illinois taxes wage income at a flat 4.95% with no local add-on, so the state share of the deduction is easy to predict at any income. What varies is the federal side.

The floor: Illinois minimum wage

The statewide minimum wage reached $15.00 an hour on January 1, 2025 and stays there in 2026, with no further increase scheduled without new legislation. Full time at that rate is $31,200 a year gross and about $25,705 after tax. Chicago sets its own floor at $17.05 from July 1, 2026, and suburban Cook County $15.40 — the only meaningful geographic variation in Illinois pay law, since income tax is identical statewide.

Using wage data when you negotiate

Find your occupation's median, not the state mean. The BLS occupational survey publishes 10th, 25th, 50th, 75th and 90th percentile wages by occupation and metro area. The 75th percentile of your occupation in your metro is a more defensible anchor than any statewide average.

Use the pay transparency rules. Since January 2025, Illinois employers with 15 or more employees must publish a pay scale and benefits description in job postings. That is free, current, employer-specific market data, and it is worth reading across a dozen listings before any salary conversation.

Negotiate the total, not the headline. A $5,000 raise is worth about $3,270 after tax at a $75,000 base. An extra 3% of employer 401(k) matching on the same salary is worth $2,250 pre-tax and costs you nothing — and Illinois never taxes it, on the way in or the way out.

Check what the offer is actually worth. Run both numbers through the Illinois paycheck calculator before deciding. A higher salary with worse health coverage frequently loses to the alternative once Section 125 premiums are accounted for.

People also ask about salaries in Illinois

It depends which survey you use, which is why published figures vary so widely. The Bureau of Labor Statistics puts the mean annual wage across all Illinois occupations at $67,130 (May 2023 OEWS, the most recent complete statewide table), while the quarterly census of employment and wages shows an average weekly wage of $1,662 for Q1 2025 — roughly $86,400 annualized. The two differ because the weekly figure includes bonuses and stock compensation that the occupational survey excludes. Median household income, a different measure again, is $83,211.

Sources

Wage statistics are drawn from the most recent published federal surveys and are labeled with their reference period. Surveys are released on different schedules, so figures from different sources are not always directly comparable. After-tax figures are estimates using 2026 rates.
