Illinois cost of living is 8.6% below the national average, but property taxes are the 2nd highest in the U.S. — here's what that means for your wallet.
Destiny Williams, a 33-year-old marketing director in Atlanta, Georgia, was making around $68,000 a year when she started daydreaming about a move to Illinois. Her company had a satellite office in Chicago, and she'd heard the cost of living was lower. But when she started crunching numbers, she hit a wall. Her first estimate — based on a generic online calculator — suggested she'd save roughly $400 a month. That felt too good to be true. And it was. She hadn't factored in Illinois's notoriously high property taxes or the state's flat income tax rate. Her real savings, after a deeper dive, looked more like $150 a month — and that was only if she lived in a specific suburb, not downtown Chicago. The uncertainty made her hesitate.
According to the Council for Community and Economic Research's 2026 Cost of Living Index, Illinois sits at 91.4 — meaning it's about 8.6% cheaper than the national average. But averages hide the real story. This guide covers three things: (1) the exact breakdown of housing, taxes, groceries, and utilities in Illinois for 2026, (2) the hidden costs that catch newcomers off guard, and (3) a clear verdict on whether the move makes financial sense for you. With the Federal Reserve holding rates at 4.25–4.50% and inflation still sticky, 2026 is a year where every dollar counts.
Destiny Williams, a marketing director from Atlanta, Georgia, thought she had Illinois figured out. She'd seen the headlines: 'Illinois is cheaper than the national average.' But when she priced out a two-bedroom apartment in a Chicago suburb, the rent was around $1,600 — not far from what she was paying in Atlanta. Then she looked at property taxes on a modest $250,000 home: roughly $5,500 a year. In Georgia, the same home would cost her around $2,800. That's when she realized the 'cheaper' label was misleading. Her first instinct was to trust the national averages, but they didn't account for the specific trade-offs Illinois demands.
Quick answer: Illinois's cost of living is 8.6% below the national average, but that number masks huge regional variation. Housing is 14% below average, but property taxes are the 2nd highest in the U.S. at an effective rate of 2.07% (Tax Foundation, 2026).
The cost of living index measures the relative price of six categories: housing, groceries, utilities, transportation, healthcare, and miscellaneous goods and services. The national baseline is 100. Illinois scores 91.4 overall, but individual categories tell a different story. Housing is 86.1 (14% below average), while utilities are 97.3 (near average). Groceries are 95.2, and healthcare is 94.8. Transportation is 97.1. The biggest outlier? Property taxes, which aren't directly in the index but are a major factor in housing costs.
Compared to its neighbors, Illinois is a mixed bag. Indiana has a cost of living index of 90.2 — slightly cheaper — with property taxes around 0.85%. Wisconsin is 92.7, with property taxes near 1.65%. Iowa is 89.4. Missouri is 87.6. Kentucky is 90.1. So Illinois is not the cheapest option in the region, but it offers something the others don't: Chicago's job market and cultural amenities. The trade-off is real.
Most people assume 'lower cost of living' means everything is cheaper. In Illinois, housing is cheaper, but property taxes eat into that savings. A $275,000 home in Illinois costs around $5,700 in annual property taxes. The same home in Texas (no state income tax) would cost around $4,100 in property taxes. The difference is real — roughly $1,600 a year. Don't just look at the home price; look at the total monthly payment including taxes and insurance.
| Category | Illinois Index | National Average | Difference |
|---|---|---|---|
| Overall | 91.4 | 100 | -8.6% |
| Housing | 86.1 | 100 | -13.9% |
| Groceries | 95.2 | 100 | -4.8% |
| Utilities | 97.3 | 100 | -2.7% |
| Transportation | 97.1 | 100 | -2.9% |
| Healthcare | 94.8 | 100 | -5.2% |
In one sentence: Illinois is cheaper overall but property taxes are a hidden anchor.

In short: Illinois's cost of living is below average, but property taxes and regional variation mean you need to do a city-by-city comparison.
The short version: You can estimate your Illinois cost of living in 3 steps — takes about 30 minutes. You'll need your current budget, a target city, and a calculator like the one from Bankrate or NerdWallet.
Our marketing director from Atlanta learned this the hard way. She started with a generic online calculator and got a number that was too optimistic. The real process is more detailed. Here's how to do it right.
List every expense category: housing, utilities, groceries, transportation, healthcare, and discretionary spending. Use your bank statements from the last 3 months. Don't guess — actual numbers matter. For Destiny, her Atlanta baseline was around $4,200 a month for a single person renting a two-bedroom apartment.
Don't use a single 'cost of living' multiplier. Instead, adjust each category individually. For housing, use 0.86 (14% less). For groceries, use 0.95. For utilities, use 0.97. For transportation, use 0.97. For healthcare, use 0.95. For everything else, use 0.92. Then add the property tax impact if you're buying a home. Destiny's adjusted budget came to around $3,850 a month — a savings of roughly $350 a month, not the $400 she first thought.
Most people forget to adjust for state and local taxes. Illinois has a flat income tax of 4.95% — no deductions for federal taxes paid. Georgia has a progressive income tax with rates from 1% to 5.75%. For someone earning $68,000, the difference is about $800 a year more in Illinois. Factor that in.
Property taxes are the biggest hidden cost. If you're buying a home, add 2.07% of the home's value annually. For a $275,000 home, that's $5,700 a year. Also factor in higher sales tax in Chicago (up to 10.25%) and higher car insurance rates — Illinois is 12th highest in the U.S. for auto insurance (Insure.com, 2026).
If you're self-employed, your tax situation is more complex. Illinois doesn't allow deductions for federal self-employment tax. You'll also need to budget for quarterly estimated tax payments to both the IRS and the Illinois Department of Revenue. The state's flat tax makes it simpler than some states, but don't forget the local taxes if you live in Chicago or Cook County.
| City | Cost of Living Index | Median Rent (2BR) | Median Home Price | Effective Property Tax Rate |
|---|---|---|---|---|
| Chicago | 94.2 | $1,800 | $320,000 | 2.12% |
| Naperville | 96.1 | $1,700 | $450,000 | 2.05% |
| Springfield | 85.3 | $1,100 | $180,000 | 2.01% |
| Peoria | 83.7 | $950 | $150,000 | 1.98% |
| Rockford | 82.1 | $900 | $140,000 | 2.10% |
Step 1 — Housing Reality: Compare rent vs. buy using the 5% rule — if rent is less than 5% of home price, renting is cheaper.
Step 2 — Tax Total: Add income tax + property tax + sales tax. Illinois's total tax burden is around 9.7% of income (Tax Foundation, 2026).
Step 3 — Lifestyle Offset: Factor in Chicago's higher wages. The median household income in Chicago is $65,000 vs. $58,000 in Atlanta.

In short: Calculate your baseline, adjust category by category, and add property taxes — that's the real Illinois cost.
Hidden cost: Property taxes are the biggest trap — averaging $5,700 per year on a $275,000 home, which is $2,900 more than the national average (Tax Foundation, 2026).
On the surface, yes. But Texas and Florida have no state income tax. Illinois has a flat 4.95% income tax. For a household earning $80,000, that's $3,960 a year in state income tax. In Texas, you'd pay $0. But Texas has higher property taxes (around 1.6%) and higher sales tax. The total tax burden in Illinois is around 9.7% of income, compared to 8.2% in Texas and 7.1% in Florida (Tax Foundation, 2026). The difference is real — roughly $1,200 a year more in Illinois.
Illinois has the worst-funded state pension system in the U.S., with a funded ratio of around 45% (Pew Charitable Trusts, 2026). This means the state has a massive long-term debt. In theory, this could lead to higher taxes in the future. In practice, it hasn't caused immediate problems for residents, but it's a risk factor. If you're planning to stay in Illinois for 10+ years, consider the possibility of future tax increases.
Illinois has the 12th highest car insurance rates in the U.S., with an average annual premium of $1,850 (Insure.com, 2026). That's about $300 more than the national average. Chicago rates are even higher — around $2,200 a year. Factor this into your transportation budget.
If you're moving to Illinois, consider living just across the border in Indiana or Wisconsin. You can work in Illinois (and pay Illinois income tax) but live in a lower-tax state. This is a common strategy for people who work in Chicago but live in Northwest Indiana, where property taxes are around 0.85% instead of 2.07%. The commute is about 45 minutes, but the savings can be $3,000-$5,000 a year.
Utilities in Illinois are near the national average (index of 97.3). But winter heating costs can spike. Natural gas prices in Illinois averaged $0.85 per therm in 2026 (EIA, 2026), which is about 10% above the national average. If you're in a drafty older home, your winter heating bill could be $300-$500 a month. Budget for it.
| Expense | Illinois Average | National Average | Difference |
|---|---|---|---|
| Property taxes (annual) | $5,700 | $2,800 | +$2,900 |
| State income tax (on $80k) | $3,960 | $3,200 (avg) | +$760 |
| Car insurance (annual) | $1,850 | $1,550 | +$300 |
| Winter heating (monthly) | $350 | $280 | +$70 |
| Sales tax (Chicago) | 10.25% | 7.5% (avg) | +2.75% |
In one sentence: Property taxes and car insurance are the two biggest hidden costs in Illinois.

In short: Illinois's hidden costs — property taxes, car insurance, and winter heating — can add $4,000+ a year to your budget.
Bottom line: Illinois is worth it if you're moving for a job in Chicago or the suburbs, and you're renting. It's less attractive if you're buying a home or retiring on a fixed income.
| Feature | Illinois | Indiana (Alternative) |
|---|---|---|
| Control over taxes | Low — high property taxes, flat income tax | Moderate — lower property taxes, flat income tax |
| Setup time for move | 2-3 months | 1-2 months |
| Best for | Job seekers, renters, urbanites | Homebuyers, retirees, families |
| Flexibility | High in Chicago, low in rural areas | Moderate statewide |
| Effort level | High — complex tax and housing market | Low — simpler market |
✅ Best for: Professionals with job offers in Chicago or the suburbs who plan to rent. Also good for people who value urban amenities and can handle the higher taxes.
❌ Not ideal for: Retirees on fixed incomes (property taxes will eat your budget). Also not ideal for homebuyers who want low property taxes.
Best case: You rent in Chicago, earn $80,000, and your total cost of living is around $3,500 a month. Over 5 years, you save roughly $12,000 compared to the national average. Worst case: You buy a $275,000 home in the suburbs, and property taxes + insurance + maintenance cost you $15,000 a year more than the national average. Over 5 years, you lose $30,000. The difference is dramatic.
Illinois is a good deal for renters in Chicago. It's a bad deal for homebuyers in the suburbs. If you're buying, look at Indiana or Wisconsin instead. The math is unforgiving.

In short: Illinois is worth it for renters and job seekers, but homebuyers should look elsewhere.
It depends. Illinois has a lower cost of living index (91.4 vs. 92.7 for Texas), but Texas has no state income tax. For a household earning $80,000, Texas saves you about $3,960 a year in income tax, but Illinois has lower property taxes (2.07% vs. 1.6% in Texas). The total tax burden is about 9.7% in Illinois vs. 8.2% in Texas.
For a single person in Chicago, you need around $55,000 a year to live comfortably (covering rent, utilities, food, transportation, and savings). In smaller cities like Springfield or Peoria, that drops to $40,000. These numbers assume renting, not buying.
It depends on where you're moving from. If you're coming from a high-cost state like California or New York, Illinois will save you money. If you're coming from a low-cost state like Mississippi or Arkansas, Illinois will cost you more. Also, check if your employer adjusts salary for cost of living.
You can apply for a property tax deferral if you're 65 or older, or if you have a disability. The deferral allows you to postpone payment until you sell the home or die. Otherwise, unpaid property taxes lead to a tax lien and eventually foreclosure. The process takes about 2 years.
Indiana is cheaper overall (index 90.2 vs. 91.4). Indiana has lower property taxes (0.85% vs. 2.07%) and a flat income tax of 3.15% vs. 4.95%. For a $275,000 home, you save $3,300 a year in property taxes alone. Indiana is better for homebuyers and retirees.
