Office pay in Illinois after taxes: what you keep (2026)

The median administrative assistant in Illinois earned $47,890 a year in May 2024, which is $23 an hour for a full-time year, according to the Bureau of Labor Statistics. Half of the 79,440 administrative assistants the BLS counts in Illinois earned more than that and half earned less; the middle half of them sat between $38,850 and $60,080. That is the gross figure, before anyone takes anything. What you keep depends on Illinois's tax, and Illinois has a flat 4.95% state income tax.

Of the 50 states, Illinois ranks 11 of 50 on the gross median for administrative assistants. The highest-paying state is Connecticut at $55,690 and the lowest is Mississippi at $36,000. Gross rank is not take-home rank: a state with no income tax climbs several places once the state line is applied, and a high-tax state drops.

None of Illinois's neighbours beats it on take-home for administrative assistants. Wisconsin, Iowa, Indiana, Kentucky and Missouri pay less once tax is counted. Pay is one line; rent is the other, and a higher median in a metro with higher rent can leave you with less.

Where the administrative assistant jobs are in Illinois

The BLS count of 79,440 administrative assistants is statewide. The metros with the most of that work are Chicago, Aurora, Naperville, Rockford and Springfield, which is where the median is set and where the upper quartile ($60,080 and above) is most often paid. Employers who could not hire locally and have filed with the Department of Labor are listed on the Illinois openings page; those filings are the ones already paying to bring people in, and housing or transport is often part of the offer.

What people get wrong about administrative assistant pay in Illinois

• Quoting the mean. The BLS mean for Illinois is $25 an hour, pulled up by the top earners. The median ($23) is what the typical administrative assistant makes.
• Comparing gross across states. A $47,890 offer in Illinois is $38,092 in hand; the same number in a no-tax state is $40,463.
• Forgetting the employer's share of insurance. A job that pays $45,890 with full health coverage can beat one that pays $50,890 without it.
• Treating the statewide median as the metro median. Chicago pays differently from a rural county; ask for the figure for the place you are actually going.
