Chicago Metro & the Collar Counties, Illinois

Retiring to Chicago, IL — The Honest Review

Chicagoland is the deepest 55+ market we cover — 40+ communities across eight counties — and it has a genuinely rare tax feature: Illinois taxes none of your retirement income. It is also the highest property-tax market we cover. Both things are true, and the second one changes the math on the first. Here is the balanced version.

The Income-Tax Case for Chicagoland

Zero state tax on any retirement income

Illinois exempts 100% of retirement income from state tax — Social Security, pensions, and 401(k)/IRA withdrawals, with no thresholds or age limits. A couple pulling $120,000/year from those sources pays $0 in Illinois state income tax on it.

The deepest community bench we cover

40+ active adult communities spanning Cook, DuPage, Kane, Will, Lake, McHenry, Kendall, and DeKalb counties — from the 5,489-home Sun City Huntley flagship down to small 50-home developments, in HOA-fee ranges from about $135/month to $750/month.

Four real senior property-tax relief programs

An assessment freeze for income-qualified seniors 65+, a tax-deferral loan program, a Circuit Breaker rebate worth up to $700/year, and a general homestead exemption worth roughly $200–$600/year — genuinely more relief infrastructure than most markets we cover.

Real choice in bundled service level

From Sun City Huntley’s $143/month HOA to Lake Barrington Shores’ all-inclusive $450–$600/month — you can buy the exact level of maintenance and amenity bundling you want, not a one-size-fits-all fee.

Cook County vs. the Collar Counties

In Chicagoland, which side of the county line your community sits on changes both your assessment method and your effective tax rate. This is the single biggest lever in the market.

Cook County

  • Residential property is assessed at just 10% of market value — unique in Illinois.
  • Effective property tax rate runs roughly 2.0–2.5%.
  • Home to established mid-size communities like Rob Roy Country Club Village (Prospect Heights), The Pines (Tinley Park), and Haverford Place (Hoffman Estates).
  • Closer to the city core, Lake Michigan, and Chicago-proper healthcare and cultural institutions.

The Collar Counties

  • DuPage, Kane, Will, Lake, McHenry, Kendall, and DeKalb all assess near 33.33% of market value.
  • Effective rates span the widest range in the metro: as low as ~1.8% in DuPage, as high as ~2.8% in Lake County.
  • Home to the biggest communities by far — Sun City Huntley (5,489 homes, McHenry County) and Carillon (2,097 homes, Will County).
  • More new construction and larger lots, further from the Loop, closer to open exurban land.

Where Property Tax Eats the Income-Tax Win

The highest property taxes of any market we cover

Expect roughly $8,000–$12,000/year on a $400K home, an effective rate of about 2.0–2.8% depending on county — with Lake County running the highest in the metro and DuPage the lowest.

Real winters, not a mild-climate sales pitch

This is the trade a Chicago-metro retiree is explicitly making against Sun Belt markets. If escaping cold and snow entirely is the primary goal, this market only partially delivers it.

The income-tax win can shrink fast against property tax

On a $350K home, Illinois’s estimated total tax burden (roughly $7,000–$8,750/year) can still run higher than a comparable Arizona scenario (roughly $4,900–$5,600/year) — even though Arizona charges state income tax on retirement income and Illinois does not. The $0 income-tax line is not the whole story.

The “Carillon” name covers seven different communities

Carillon (Plainfield), Carillon Lakes, Carillon Club, Carillon at Stonegate, Carillon North, and others share the brand name across the metro but are separate developments with different builders, prices, and HOA structures — an easy way to research the wrong one if you are not careful.

County assessment rules add real complexity

Cook County assesses residential property at just 10% of market value, a method unique in Illinois, while every collar county assesses near 33.33%. The same home price can carry a meaningfully different bill purely based on which side of a county line it sits on — worth confirming with a local tax professional rather than assuming.

Does the $0 Income-Tax Line Actually Win?

Good Fit

Buyers who want to stay close to family in the Chicago area, have meaningful pension or retirement-account income where Illinois’s full exemption is worth real money, want the largest possible selection of communities to comparison-shop, and are willing to treat property tax — not income tax — as the number that decides the budget.

Run the Numbers Elsewhere Instead

Buyers whose primary goal is escaping winter entirely, who want the lowest possible total tax burden regardless of income mix, or who want one simple statewide tax number rather than a county-by-county spreadsheet — a warmer, lower-property-tax market is likely the better fit for that specific profile.

Run the county-specific numbers, and price in a real winter, before assuming the $0 state income-tax line makes this the cheaper choice — it is a real win that property tax can just as easily erase.
