Illinois Cost of Living Overview

Understanding the cost of living in Illinois means looking at taxes, housing, and everyday expenses together. Illinois levies a flat income tax, which directly impacts take-home pay. The average property tax rate is 1.79%, and the state sales tax rate is 6.25%.

Cost of living in Illinois comes down to a tax mix that is easygoing in two places and demanding in a third. Income tax is the predictable part: a flat 4.95% with no added tiers and no tax on Social Security, pensions, or qualified retirement distributions. Sales tax opens at 6.25% statewide, though local add-ons lift the register total in many cities. The strain shows up in property tax, where the roughly 1.79% average effective rate, about double the national figure, can add thousands of dollars a year to homeownership and feeds quietly into rents as landlords pass the expense along.

Housing is what separates one region from another. A salary that feels generous downstate or in a smaller metro often goes much further than the same figure in the Chicago area, where home prices and local levies climb together. When weighing two offers, look past the headline number: the flat 4.95% income tax follows you anywhere in the state, but property tax rates, local sales taxes, and rent shift from county to county. A larger nominal salary in a high-tax suburb can leave you with less spendable income than a smaller one in a lower-cost county.

Local/City Taxes Local sales taxes (home rule, county, and special-district) add up to ~4.75% on top of the 6.25% state rate, for combined rates up to ~11%.

City indexes (U.S. average = 100) are planning estimates on one scale. The 29 cities added in August 2026 were reconciled from BestPlaces city pages, the Payscale and RentCafe cost-of-living calculators (both built on the C2ER Cost of Living Index) and the MERIC state index for Q1 2026; the original 30 large metros date from April 2026 and have not been re-checked since. Local rents and home prices can differ a lot within a metro, and the equivalent salary does not account for income taxes.

Illinois Cost of Living FAQ

What creates the biggest cost gaps inside Illinois?
Housing prices and property taxes are the main variables. Income tax is a flat 4.95% statewide and the sales tax base is a uniform 6.25%, but the roughly 1.79% average effective property tax rate and home values diverge widely between Chicago-area counties and downstate ones. Two households earning the same income can run very different budgets depending largely on where they live and whether they own or rent.
How should I weigh a Chicago offer against a downstate one?
Apply the same flat 4.95% income tax to both, then adjust for what actually varies: local sales tax add-ons, the property tax rate or rent, and commuting cost. Chicago-area offers often arrive with steeper housing and local taxes that can chip away at a higher salary. Comparing estimated take-home against typical housing cost in each place reads truer than salary alone.
Does Illinois' high property tax reach renters?
Yes, indirectly. Landlords carrying the roughly 1.79% average effective rate generally fold that cost into the rent they charge, so even non-owners absorb part of it. In suburbs and counties with steep composite rates, that pass-through can make rent meaningfully higher than in lower-tax parts of the state. Renters also miss the homestead exemptions that owner-occupants can claim.
Is Illinois friendly to retirees on a budget?
On the income side, frequently yes: Illinois doesn't tax Social Security, pensions, or qualified retirement-plan distributions, which can sharply cut a retiree's state tax bill. The counterweight is property tax, where the high average effective rate raises the cost of owning a home. Senior exemptions and the assessment freeze for qualifying lower-income owners can ease that, so the overall picture hinges on housing as much as income.
