Salary needed to live in Illinois
Typical lifestyle. We take the U.S. median household income of $81,604, taxed as a single filer in a typical state, and find the Illinois salary that buys the same after taxes at Illinois prices (price level 100.0, where the U.S. = 100). At $86,400, a single filer here pays $10,178 federal income tax, $6,610 Social Security and Medicare, and $4,132 state income tax, keeping $65,480. A married couple filing jointly needs about $86,600 of combined pay, measured against a couple earning the U.S. median taxed jointly. That figure differs from the single-filer one only because of joint tax rates; it isn't a larger budget for two people. For that, see the salary needed for a couple or a family.
Renting. The median Illinois rent is $1,322 a month, 11% below the U.S. median of $1,487. Keeping it to 30% of gross pay, a common affordability line, takes $52,880 a year.
Buying. The median Illinois home is worth $280,700, 22% below the U.S. median. Lenders prefer housing costs under 28% of gross income, so it takes about $87,942 with 20% down, or $100,416 with 10% down (including mortgage insurance).
Taxes. Taxes push Illinois up the ranking: it's #18 of 51 for prices but #15 for the salary needed, because its state taxes are heavier than those of states with similar prices. Illinois taxes wages at a flat rate: about $4,132 at the typical-lifestyle salary, or 4.8% of pay. Homeowners pay a median $5,399 a year in property tax, about 1.92% of the median home's value, against 0.89% nationally.
Salary needed for a family in Illinois
A family of four, two adults with children aged 4 and 9, needs about $180,400 a year in Illinois to live like the single adult above, sized for four people. A single parent with one child needs about $143,200, and a couple without children about $108,000. For comparison, the median four-person household in Illinois earned $132,436 in 2024 (Census ACS table B19019 (opens in new tab)). Our figure is higher because it starts from what the median U.S. household earns, whatever its size, and sizes that standard of living up for four people.
The single adult's typical-lifestyle salary above leaves $49,616 a year after taxes and rent for everything else: food, transportation, health care, utilities, savings and the rest. A bigger household needs more of that. We scale it with the Census Bureau's equivalence scale for household size, the one behind its Supplemental Poverty Measure (opens in new tab): 1.41 times as much for a couple, 1.51 for a single parent with one child and 2.16 for two adults with two children. Each household also pays the median rent for a home with enough bedrooms (two with children) and full-time center care for a child under 5, and its taxes use its own filing status and child tax credits.
| Household | Salary needed | Taxes | Rent | Child care | Everything else |
|---|---|---|---|---|---|
| Single adult single filer | $86,400 | $20,920 | $15,864 all homes | none | $49,616 |
| Couple, no children married, joint | $108,000 | $21,918 | $15,864 all homes | none | $70,218 |
| Single parent, 1 child head of household; age 4 | $143,200 | $35,057 | $15,996 2 bedrooms | $17,238 | $74,909 |
| Family of 4 married, joint; ages 4 and 9 | $180,400 | $40,069 | $15,996 2 bedrooms | $17,238 | $107,097 |
This is a modeled lifestyle benchmark, not a minimum income requirement. Its starting budget uses national median household income as a single-adult reference before scaling for larger households; family estimates can therefore exceed what typical families earn. Use your own expenses in the personal move budget for an individual plan. Taxes: 2026 federal and Illinois income tax with the standard deduction, Social Security and Medicare. Households with children get the federal child tax credit ($2,200 a child). The federal child and dependent care credit isn't counted; on the 4-year-old's care it is worth $600 to $1,050 at these incomes (20% to 35% of $3,000), so taxes for those households may be that much lower. Any state exemption or deduction for dependents isn't included, so where the state has one, state tax for the households with children may be a little lower. The single parent files as head of household; Illinois taxes a head of household like a single filer.
Child care: full-time center care for the 4-year-old at Child Care Aware of America's 2024 Illinois average price; the 9-year-old is in school, and before- and after-school care isn't counted. Rent: Census ACS 2024 median gross rent for all homes, or for two bedrooms with children (table B25031). These are the move calculator's own figures: see the family of 4 in the calculator.
