Illinois is the Prairie State, anchored by Chicago — one of the top global cities in the US. The 4.95% flat income tax is among the highest flat rates in the US (was 7% before 2015 cuts), and the 1.88% effective property tax is the 2nd highest in the country. The combination of high property tax and high income tax makes Illinois one of the highest-tax states in the Midwest. For FIRE planners, the math is mixed: Chicago offers unmatched urban opportunities, but the tax burden is meaningful.
Chicago is the FIRE story within Illinois. The metro (9.5M population) hosts major employers in finance (CME Group, Northern Trust), tech (Google, Salesforce, Amazon AWS), healthcare (Northwestern, Rush, Advocate), and professional services. Median home prices vary dramatically: downtown Chicago condos are $400K-$800K, suburban Cook County is $350K-$450K, exurban Will and DuPage counties are $400K-$500K, but property tax is 1.5-2.5% across the metro. The trade-off: world-class opportunities offset by high taxes.
Downstate Illinois (Springfield, Champaign, Bloomington, Carbondale) is the underappreciated FIRE story. Median home prices around $200K (statewide) are 60% below the national median, with the same 4.95% flat tax but lower property tax (1.5-2.0% still high but lower than Chicago metro). The state pension crisis and fiscal instability create long-term risk, but for short-to-medium-term FIRE planning, downstate Illinois offers a low-cost-of-living option with access to Chicago cultural amenities (via a 2-3 hour drive or Amtrak).

Recommended Withdrawal Strategy in Illinois
4% rule works but the high property tax and 4.95% flat income tax reduce the FIRE math. Consider Chicago for urban opportunities, Springfield/Champaign for low cost of living, and the suburbs for family FIRE. The 4.95% flat tax on IRA withdrawals is meaningful — consider no-income-tax states for retirement.

Frequently Asked Questions About FIRE in Illinois
Why is Illinois property tax so high?
Illinois has the 2nd highest effective property tax rate in the US (1.88% effective, behind only New Jersey). The high rate is driven by municipal pension obligations, school funding shortfalls, and the state pension crisis (the worst-funded in the US). For Chicago-area homeowners, property tax is the single largest expense category, often exceeding mortgage interest. Cook County (Chicago) has some of the highest property tax rates in the country at 1.8-2.5% effective.
Is Chicago worth the high taxes for FIRE?
For high-income professionals earning $300K-$500K, the Chicago math can work. A senior tech worker or finance professional at $400K total comp pays $19,800 in Illinois state tax (4.95% flat) — versus $0 in Texas or Florida. The cost: $0 in state tax + lower cost of living = ~$20K/year savings in no-income-tax states. Over a 20-year career, that is $400K in additional wealth. The trade-off: access to top-tier cultural amenities, world-class healthcare, and the Chicago job market.
Does Illinois tax Social Security?
No. Illinois fully exempts Social Security benefits from state income tax. This is consistent with about 40 states. Combined with the 4.95% flat tax, this makes Illinois less tax-efficient for retirees than no-income-tax states but more efficient than states with both income tax and Social Security tax.
What is the Illinois pension crisis and why should FIRE planners care?
Illinois has the worst-funded state pension system in the US, with $140B+ in unfunded pension liabilities as of 2024. The state constitution protects pension benefits, meaning the gap must be closed through higher taxes or reduced services. For FIRE planners, the long-term fiscal risk means Illinois tax rates may rise or services may decline. The state has implemented a 2017-2025 tax schedule with a constitutional amendment switching from flat to graduated income tax, but the graduated tax was rejected by voters in 2020.
