The Best Places to Retire in Illinois

Illinois is a large, flat, well-connected Midwestern state, and for retirees the map of where 55+ life actually happens is easier to read than you might expect. Nearly all active adult communities cluster in the Chicago suburbs and the collar counties that ring the metro: DuPage, Will, Lake, Kane, and McHenry. That's where you'll find the state's marquee 55+ communities, including Del Webb's Sun City Huntley in McHenry County, one of the largest age-restricted communities in the Midwest, plus a deep bench of smaller Del Webb and builder-led neighborhoods in Naperville, Plainfield, Joliet, Elgin, and Grayslake. On the site, that whole belt falls under one hub: the Chicago Suburbs.

The single biggest reason Illinois belongs on a retiree's shortlist is its treatment of retirement income. The state has a flat 4.95% income tax, and it fully exempts retirement income from that tax. Social Security, pension distributions (public and private), and withdrawals from 401(k)s, traditional and Roth IRAs, and other qualified plans are all subtracted from Illinois taxable income. For a household living on Social Security, a pension, and IRA withdrawals, the state income tax bill can be effectively zero, and for higher-income retirees with sizable pensions or large RMDs, the savings compound year after year.

The honest counterweight is property tax, and it's a big one. Illinois property taxes consistently rank first or second in the nation, with an average effective rate between 1.88% and 2.07%, well over double the U.S. average of roughly 1.0%. WalletHub's 2025 survey put the average Illinois family's annual property tax bill at $6,285 on a median U.S. home, and Cook County and the collar counties often run higher. There is no age at which Illinois seniors stop paying property taxes (that's a common myth), but there is meaningful relief. Homeowners 65 and older can claim the Senior Citizens Homestead Exemption, which knocks $8,000 off equalized assessed value in Cook and the collar counties and $5,000 in most other counties, on top of the General Homestead Exemption. Qualifying seniors under the income cap (currently $65,000 household income, rising to $75,000 for the 2026 tax year under a recently signed law) can add the Low-Income Senior Citizens Assessment Freeze, which locks the EAV in place so future assessment increases don't ratchet the bill up further. Illinois also runs a Senior Citizens Real Estate Tax Deferral Program that lets homeowners 65 and older defer part or all of their property taxes as a lien against the home, repaid at sale or from the estate.

Sales tax runs above the national average once local add-ons are layered in. The state rate is 6.25% and the combined average is closer to 8.96%, though groceries and prescription drugs are taxed at reduced rates. Estate planning deserves real attention here. Illinois has its own estate tax with a $4 million exemption that has not moved in years and is not portable between spouses, while the federal exemption sits at roughly $15 million per person. That gap means estates that owe nothing federally can still face a substantial Illinois estate tax, with rates climbing to a top marginal 16%. In pricier Chicago suburbs, a paid-off home, retirement accounts, and life insurance can push a couple past the $4 million threshold faster than they expect, so anyone in that range should talk to an estate planning attorney about trusts and lifetime gifting.

Illinois has four genuinely distinct seasons. Summers are warm to hot and humid, with stretches of 80s and 90s and occasional thunderstorms rolling across the plains, while spring and fall are pleasant and comparatively short. Winters are the trade-off: cold, gray, and snowy, with sustained sub-freezing stretches and real planning required around ice, snow removal, and shorter daylight.

Near Chicago and along Lake Michigan, lake-effect can intensify snowfall and sharpen the chill off the water, though the lake also moderates extreme summer heat. Central and southern Illinois see slightly milder winters and more tornado risk in spring. For 55+ buyers, the practical takeaway is straightforward: a low-maintenance home and an HOA that handles snow removal and landscaping are worth a lot in Illinois, and plenty of retirees build a January-to-March getaway into their routine.

Illinois lands close to the national average overall, but the mix underneath is unusual: home prices are relatively affordable, utilities run below average, and property taxes are among the highest in the country. The statewide median home price is around $320,000 to $357,000 depending on the source, well below the U.S. median of roughly $446,000. Outside the Chicago metro, in central Illinois and the Metro East, you can find 55+ product for meaningfully less. Even in the suburbs, active adult inventory spans attached villas and townhomes up through amenity-rich Del Webb-style ranch homes, so most budgets have room to work.
