Learn moreA genuinely high effective property tax rate
Arlington Heights' Cook County-side median effective property tax rate runs 2.52% (a separate source cites 2.59%), both meaningfully above Cook County's own 2.14% median. Bills range from a real, disclosed $7,414 (ZIP 60005) to $8,795 (ZIP 60004), driven primarily by differing school-district levies rather than one flat villagewide rate.
Illinois's flat income tax and full retirement-income exemption
Illinois levies a simple flat 4.95% tax on wages statewide (see illinois.js) -- but Illinois taxes NONE of a retiree's Social Security, pension, or 401(k)/IRA income, with no age or income threshold. This is a real, substantial positive for retirees living in Arlington Heights specifically, distinct from the village's own high property tax burden.
Confirm your specific county and school district
Because Arlington Heights spans both Cook and Lake counties, and because property tax bills vary meaningfully by ZIP code within the village due to school-district levies, confirm your specific target address's current combined rate directly rather than budgeting against one villagewide figure.
Statewide, tornado-driven insurance cost pressure
Arlington Heights inherits Illinois's real, statewide, currently escalating homeowners-insurance cost trend -- driven by 2026's record 202+ confirmed tornadoes statewide and the August 2026 northern-Illinois derecho -- rather than carrying a village-specific insurance risk distinct from the rest of the Chicago area.
