Computer and Information Systems Manager Salary in Illinois: Pay by Experience, City & Take-Home

A computer and information systems manager in Illinois earns a median of $171,730 a year, or about $82.56 an hour, according to the U.S. Bureau of Labor Statistics (2025). Most people in the role land between $133,220 and $212,040, with entry pay near $105,350 and the top 10 percent clearing $273,500. That puts Illinois just under the national median for the job.

How Illinois pay compares to the national number

The national median for computer and information systems managers is $175,140, per the BLS (2025). Illinois sits at $171,730, so the typical manager here earns about $3,410 less than the national midpoint. That’s a gap of roughly 2 percent, small enough that it won’t decide where you live, but worth knowing when you’re weighing an offer against a recruiter’s “this is what the role pays nationally” line.

The spread inside Illinois matters more than the gap to the national figure. The 10th percentile sits at $105,350 and the 90th at $273,500. That’s a $168,150 range from the bottom to the top of the field, driven by company size, industry, and how much of the org’s tech budget you actually control. A manager running infrastructure at a mid-size firm and a VP-track director at a Chicago financial company carry the same SOC code but live in different pay worlds. The state mean is $179,190, higher than the median, which tells you the top earners pull the average up. When a distribution’s mean beats its median like this, big paychecks at the top are doing the lifting.

With 31,680 people employed in the role statewide, Illinois is one of the larger markets for the job in the country. That depth matters when you change jobs, because more employers competing for the same managers keeps pay honest.

It’s also worth being clear about what “computer and information systems manager” covers, because the SOC code (11-3021) bundles a wide set of titles. IT directors, infrastructure managers, applications development managers, data center leads, and the people who carry “VP of IT” on the org chart can all report under it. That breadth is exactly why the Illinois range runs from $105,350 to $273,500. The title on your business card matters less to your pay than the size of the budget and team you control, and the industry writing the checks. A reader comparing their own number to the $171,730 median should anchor on those two factors first.

Pay by experience level

Pay for this role climbs steeply with scope and tenure. The BLS percentile points are the cleanest way to read that progression, since they reflect what real managers in Illinois actually earn at each rung. Here’s the breakdown.

The jump from early career to the median is about $38,510. The jump from the median to experienced pay is another $40,310. Those are big steps, and they usually come from one of two things: managing a larger team and budget, or moving into a higher-paying industry. The leap from the 75th to the 90th percentile, $61,460, is the steepest of all. That top tier is where directors and divisional IT leaders sit, often with equity or bonus components that the BLS base-pay figures don’t fully capture. If your total comp includes meaningful bonus or stock, your real number can run above these percentile lines.

One practical read: if you’re a new manager near $105,350 and you’re stuck there after two or three years, the data says the next $28,000 to the 25th percentile is normal market movement, not a stretch goal. Use these numbers as bargaining power in a review conversation.

It helps to translate the percentiles into hourly terms too, because that’s how some contract and consulting roles get priced. The median works out to $82.56 an hour. Entry pay at the 10th percentile is about $50.65 an hour, early-career pay at the 25th is roughly $64.05, the experienced 75th-percentile manager bills out near $101.94, and the senior 90th-percentile figure lands around $131.49. If you’re ever weighing a salaried offer against a contract rate, those hourly equivalents are the right yardstick, before you add back the cost of benefits a salaried role provides and a contract one doesn’t.

A word of caution on reading the median as your number. Half of all Illinois managers earn more than $171,730 and half earn less, but the distribution isn’t symmetric. The distance from the median up to the 90th percentile ($101,770) is far larger than the distance from the median down to the 10th ($66,380). In plain terms, the upside in this role is steeper than the downside, which is part of why moving from a senior individual-contributor seat into management tends to pay off over a career. The ceiling is high and the floor, by tech-salary standards, is already comfortable.

Pay by Illinois metro

Where you work inside Illinois changes the number more than most people expect. The Chicago metro holds the bulk of the jobs, but the data on the smaller metros is where this page beats a generic national overview. Here are the five Illinois metro areas the BLS reports for this role (2025).

The surprise here is Peoria. At $173,870 it edges out Chicago by $110, and both top the state median. That’s not a fluke of a tiny sample, Peoria reports 880 managers in the role, and the area’s concentration of large engineering and manufacturing employers pushes IT leadership pay up. Bloomington, home to major insurance operations, lands close behind at $169,720.

The bottom of the table tells the other half of the story. Champaign-Urbana pays a median of $140,480, which is $33,280 less than Peoria for the same job title. A chunk of that reflects the university-anchored employment base, where public-sector and academic IT roles sit below private-industry pay. Springfield, the state capital, comes in at $154,230, again reflecting a heavier government employer mix. If you’re geographically flexible inside Illinois, the gap between the top and bottom metros here is real money, $33,390 between Peoria and Champaign-Urbana, and it dwarfs the cost-of-living difference between those cities.

Chicago is where the jobs are. With 24,950 of the state’s 31,680 positions, roughly 79 percent of Illinois managers in this role work in the Chicago metro. That density means more openings, more lateral moves, and more competing offers, which is its own form of bargaining power.

The downstate metros are smaller markets, but don’t dismiss them on pay. Peoria and Bloomington both clear $169,000 at the median, and they do it with a fraction of Chicago’s cost of living. A $173,870 median in Peoria stretches considerably further than $173,760 in the Chicago metro once you account for housing. The tradeoff is volume: Peoria reports 880 positions, Bloomington 570, so openings come up less often and a job search there takes patience. For someone who values total quality of life over a deep job market, the downstate numbers make a stronger case than they first appear.

The Chicago metro figure spans the IL-IN border, so it includes northwest Indiana. That matters for take-home, because Indiana’s income tax rules differ from Illinois’s. If you live across the state line but work in the metro, your paycheck math changes even though the BLS reports you in the same area. It’s a small slice of the workforce, but worth flagging for anyone in the south suburbs weighing a move across the border.

Take-home pay after tax in Illinois

Gross salary is the headline. Take-home is what hits your account. Illinois taxes income at a flat 4.95 percent, so unlike states with graduated brackets, your state rate doesn’t climb as you earn more. Federal tax and FICA still scale up, though. Here’s the after-tax picture across the experience range, based on a single filer with standard assumptions (tax year 2026).

At the median, an Illinois manager keeps $119,630 of a $171,730 salary, an effective combined rate of about 30.3 percent. That’s $9,969 a month in your pocket. The senior tier keeps $184,394 of $273,500, where the effective rate climbs to 32.6 percent as more income hits higher federal brackets.

Notice how the state line in the table behaves differently from the federal line. Illinois state tax rises in a straight line, from $5,215 at entry to $13,538 at the senior level, because it’s a flat 4.95 percent of taxable income with no brackets. Federal tax does the opposite, jumping from $14,791 to $60,022 as income crosses into higher marginal brackets. That’s why the effective rate climbs from 26.6 percent at entry to 32.6 percent at the top: the federal system, not the Illinois one, is what makes a raise feel like it’s taxed harder. For an Illinois earner, the flat state tax is actually the predictable part of the equation.

The monthly figures are the ones to budget against. An entry manager nets $6,440 a month, the median earner $9,969, the experienced manager $12,276, and the senior tier $15,366. If you’re moving into the role from a lower-paying job, the median net of nearly $10,000 a month is the realistic number to plan a mortgage or a savings rate around, after you account for any 401(k) and health-premium deductions your employer takes before these calculations even begin.

The cross-state comparison that actually matters: take that same median earner and drop them in Texas, a state with no income tax. The Illinois manager nets $119,630. The identical earner in Texas nets $128,130. That’s a difference of $8,500 a year, money Illinois collects through its flat 4.95 percent state tax that Texas simply doesn’t levy. Over a decade, that’s $85,000 in pre-investment dollars. Before you treat that as a reason to move, run the other half of the equation: net pay minus local housing is the number that actually decides your standard of living. Texas property taxes are among the highest in the country, and a comparable home in a strong Dallas or Austin school district can erase a chunk of that $8,500 income-tax saving. Chicago suburbs carry their own high property-tax load too. The honest answer is that the $8,500 gap is real, but housing and property tax in your specific neighborhood swing the final comparison just as hard.

To pin down your own number, run your exact salary, filing status, and deductions through the Illinois paycheck calculator. When tax season comes, filing software like TurboTax handles the Illinois flat-tax return and federal filing together, which matters once you’ve got bonus income or equity in the mix.

How to earn more as an IS manager in Illinois

The percentile data shows clear room above the median. Here’s how managers in Illinois actually close the gap to the 75th and 90th percentile lines.

• Move toward the high-paying industries. The state mean of $179,190 running above the $171,730 median tells you the top employers, finance, insurance, and large engineering firms in Chicago, Peoria, and Bloomington, pay well above the middle. Targeting those sectors is the single biggest lever.
• Stack cloud and security credentials. Certifications in AWS or Azure architecture, plus a CISSP for security leadership, signal you can own the budget for the most expensive parts of the stack. Structured programs through Coursera let you build those credentials around a full-time job, and they map directly to the higher-budget roles that sit in the upper percentiles.
• Manage a bigger budget and headcount. The pay jump from median to experienced ($40,310) tracks scope more than tenure. Volunteering to absorb an adjacent team or own a major migration is how you justify the next band.
• Relocate within the state if you can. Peoria’s $173,870 median beats Champaign-Urbana’s $140,480 by $33,390 for the same title. Even moving from Springfield to Chicago is worth roughly $19,500 at the median.
• Negotiate total comp, not just base. The 90th percentile at $273,500 reflects base pay that’s often paired with bonus and equity the BLS doesn’t capture. When you negotiate, push on the variable components, not only salary.
• Change employers on a cycle. With 31,680 managers in the state and heavy Chicago concentration, lateral moves are how most people in this role get a real raise. Internal bumps rarely match what a competing offer pulls.

Job outlook in Illinois

Illinois employs 31,680 computer and information systems managers, with nearly 80 percent of them in the Chicago metro. That’s a deep, established market, and demand for technology leadership has held strong nationally as companies expand cloud, data, and security operations. A large existing base also means steady churn, retirements, promotions, and lateral moves that open seats even in a flat hiring year.

If you’re actively looking, set alerts on a board like ZipRecruiter and filter by metro, since the pay gap between Chicago, Peoria, and the downstate metros is wide enough to be worth targeting deliberately.

Related and higher-paying roles in Illinois

It helps to see where this role sits against the tech jobs around it in Illinois. Both common comparison roles pay less than a computer and information systems manager here, which is the expected pattern: the manager sits above the individual-contributor tracks. Using BLS Illinois medians (2025):

• A software developer in Illinois earns a median of $132,110, which is $39,620 LESS than an information systems manager in Illinois.
• A computer systems analyst in Illinois earns a median of $101,570, which is $70,160 LESS than an information systems manager in Illinois.

The takeaway for anyone on a technical track: stepping into IS management is one of the larger pay jumps available inside the field, $39,620 over a senior developer at the median. That gap is the case for moving into leadership if the work suits you.
