LGBTQ+ tax & cost-of-living guide: Chicago
Illinois has a flat 4.95% state income tax, one of the highest property-tax burdens in the country in Cook County (often 2.0–2.5%+ of market value), and its own estate tax with a $4M exemption (no portability). For LGBTQ+ Chicago households, the tax picture is very different from coastal markets — and the estate-tax cliff is the piece most people miss.

Illinois's flat 4.95% income tax is meaningfully lower than California or New York and simpler to model. Combined with strong statewide LGBTQ+ legal protections (marriage, parentage, non-discrimination), the state-level picture for Chicago LGBTQ+ households is genuinely favorable.
What's not favorable is Cook County property tax. Effective rates in the city and closer suburbs commonly hit 2.0–2.5%+ of market value — one of the highest sustained burdens in the country. On a $700k Chicago single-family or 2-flat, that's $14–18k+ per year, indefinitely.
The bigger planning issue is Illinois's estate tax: $4M exemption per person, no portability to the surviving spouse, progressive rates up to 16%. A paid-down Chicago home + maxed retirement + vested equity comp can push a same-sex couple over that line quickly — and without bypass-trust planning, the first-death exemption is lost.
Rather than a generic cost-of-living index, this guide focuses on the levers that matter for LGBTQ+ households: state income tax, property tax, state estate/inheritance tax, and the legal and benefits overlay specific to same-sex couples and families. When you're ready to translate any of it into a plan, the Chicago city page is the right next step.
The tax & cost levers that matter most in Chicago
IL flat 4.95% income tax
One rate on essentially all income. Simpler than progressive states, but full ordinary treatment of LTCG at the state level means IPO and RSU sequencing still matters.
Cook County property tax reality
Effective rates commonly 2.0–2.5%+ of market value in the city and inner suburbs. Homestead exemption + senior/senior-freeze programs help; assessment appeals are worth doing on a set cadence.
IL estate tax at $4M, no portability
One of the tighter state estate-tax setups in the country. Bypass-trust (credit-shelter) planning is essential for most Chicago LGBTQ+ households with a home + retirement + equity comp.
Chicago real-estate transfer taxes
City + county transfer taxes on sales. Chicago's 'Bring Chicago Home' proposal has shifted repeatedly — worth pricing into any planned sale or intra-family transfer.
Marriage-penalty math for IL earners
Two W-2s in finance, law, consulting, or Big Four in Chicago still trigger the federal marriage penalty on top of IL's flat state rate. Filing-status and deduction-bunching modeling apply here too.
