Retiring in Illinois: A State Guide for 2026

The Honest Case for Illinois

Illinois has the best healthcare ecosystem in the Midwest, and it’s not particularly close. Northwestern Medicine, Rush University Medical Center, and the University of Chicago Medicine in Chicago are nationally elite institutions. NorthShore University HealthSystem serves the northern suburbs. The University of Illinois Hospital and the OSF Healthcare system round out coverage for downstate Illinois and beyond. For Illinois residents, the healthcare backstop is genuinely world-class.

Illinois also has one of the most favorable retirement income tax structures in the country: a flat 4.95% income tax, with a full exemption for Social Security, pension income from government sources, IRA distributions, and most retirement income. For many retirees, the effective Illinois income tax on retirement income is zero, despite the headline rate.

The reason Illinois doesn’t appear on most retirement lists: property taxes are punishing (effective rate ~2.08% statewide, among the highest in the country, with Cook County running even higher), the state’s fiscal condition has been historically troubled, and Chicago’s cost of living is high. But the suburbs — particularly the DuPage County corridor (Naperville, Downers Grove, Wheaton, Glen Ellyn) and the North Shore (Evanston, Wilmette, Winnetka) — offer a quality of life that’s hard to match at any price point for people who value Midwestern infrastructure, four seasons, and cultural depth.

For downstate Illinois, Peoria (OSF Saint Francis Medical Center, one of the country’s best large community hospitals) and Bloomington-Normal (with OSF system access) offer the state’s most accessible retirement options.

Illinois Retirement Tax Snapshot

Income tax rate: Flat 4.95%.

Social Security: Fully exempt.

Pension / retirement income: Fully exempt — all pension income (IL, federal, military, other government pensions) and most IRA/retirement distributions are exempt from Illinois income tax for retirees. This is one of the broadest retirement income exemptions in the country.

Property tax: Effective rate approximately 2.08% statewide; Cook County runs higher. One of the highest effective property tax states in the country.

Estate and inheritance tax: Illinois has an estate tax with a $4M exemption (significantly lower than the federal exemption — meaningful for Illinois residents with homes, retirement assets, and life insurance combined). No inheritance tax.

Primary Retirement Regions

DuPage County (Naperville, Downers Grove, Wheaton, Glen Ellyn): One of the country’s best suburban retirement corridors; Edward-Elmhurst Health, Northwestern Medicine Central DuPage; homes $380K–$700K; Metra rail to Chicago; excellent parks and infrastructure.

North Shore (Evanston, Wilmette, Glenview): Northwestern Memorial 20–30 min away; NorthShore University HealthSystem local; Metra rail; academic/cultural character; homes $450K–$850K+.

Lake County (Libertyville, Lake Forest, Vernon Hills): Northwestern Medicine Lake Forest Hospital; Lake Michigan lakefront communities; homes $350K–$700K.

Peoria / Central Illinois: OSF Saint Francis Medical Center (nationally ranked, a major regional academic hospital); UnityPoint Health; homes $180K–$320K — among the most affordable Illinois options with genuine healthcare depth.

4 Named 55+ Communities Worth a Look

Most “55+ community” roundups rank on amenity scores alone — this section is organized by the regions covered above, so the comparison stays meaningful alongside the tax and healthcare picture already laid out.

Chicago Suburbs

Canterbury Farm — Elgin, Kane County (55+, $280K–$460K, northwest suburbs). Elgin sits about 40 miles northwest of Chicago — an accessible northwest suburban location with generally lower prices than the North Shore or DuPage corridor. Worth knowing: Northwestern Medicine Delnor Hospital in Geneva and Advocate Sherman Hospital in Elgin are the local acute care options; Northwestern Memorial Hospital (the Chicago flagship) is about an hour east on I-90, the realistic destination for complex specialty care.

Heritage Bluffs — Channahon, Will County (55+, $320K–$520K, southwest Chicago suburbs). Channahon is about 50 miles southwest of Chicago — meaningful highway distance, but Will County prices reflect that. Worth knowing: Morris Hospital is local; for major specialty care, Presence and AMITA Health locations in Joliet are about 15 miles north, with Chicago’s major academic centers (Northwestern, Rush, UChicago) an hour north on I-55.

Victorian Village — Antioch, Lake County (55+, $260K–$420K, north suburbs near Wisconsin border). Antioch’s north Lake County location puts it at the quieter, more rural end of the Chicago suburbs. Worth knowing: Advocate Condell Medical Center in Libertyville is the major Lake County system; Northwestern Medicine Lake Forest Hospital and NorthShore University HealthSystem are also accessible; the Wisconsin border proximity may introduce cross-border Medicaid considerations for residents who spend significant time in both states.

Downstate Illinois

Thorntons Ferry — Champaign-Urbana, Champaign County (55+, $220K–$380K). Champaign-Urbana’s University of Illinois campus gives it cultural and healthcare depth uncommon for a downstate community. Worth knowing: Carle Foundation Hospital is the regional anchor and carries strong subspecialty capacity for a city of its size; Champaign is about 130 miles south of Chicago, making it genuinely independent of the metro rather than an outer suburb.

Illinois Medicaid (Long-Term Care)

Key 2026 figures:

• Asset limit (single): $2,000
• Asset limit (married, one applying): $2,000 applicant; CSRA up to $109,560 (Illinois uses a lower CSRA than the standard $137,400 — worth verifying annually)
• Home equity limit: $713,000 (verify)
• Look-back period: 60 months (5 years)
• Income limit: $2,742/month for nursing home care (verify)

Illinois’s CSRA runs below the standard federal maximum, which is worth confirming with a licensed Illinois elder law attorney.

Medicare in Illinois

Plan availability is excellent in the Chicago metro and suburbs, strong in Peoria, Rockford, and Springfield, and more moderate in secondary downstate cities. Plans are county-specific, so availability is worth checking for the exact county under consideration.

If You’re Helping a Parent Evaluate Illinois Options

The Illinois estate tax exemption is low. At $4M, the Illinois estate tax exemption is significantly lower than the federal $13.6M+ exemption. A parent with a Chicago-area home ($500K–$1M+), retirement accounts, life insurance, and investment assets can easily exceed $4M — creating an Illinois-only estate tax bill that wouldn’t exist in a state without an estate tax. An estate plan that accounts for this specifically is worth having in place.

Illinois’s CSRA sits below the standard. Illinois uses a community spouse resource allowance lower than the federal maximum standard ($137,400). The exact amount is worth verifying with an Illinois elder law attorney — the difference from the standard can amount to tens of thousands of dollars in spousal protection.

The retirement income exemption is real. For a parent living primarily off a government pension and Social Security, Illinois’s effective income tax on retirement income is very low to zero. The property tax tends to be the larger financial factor and is worth the primary focus in most cases.
