Illinois's flat income tax and full retirement-income exemption
Illinois levies a simple flat 4.95% tax on wages statewide (see illinois.js) -- and taxes NONE of a retiree's Social Security, pension, or 401(k)/IRA income, with no age or income threshold. This statewide exemption applies fully to any retiree who chooses Bolingbrook, even though the village's own population skews meaningfully younger.
Confirm your specific county: Will vs. DuPage
Because Bolingbrook spans both Will and DuPage counties, and this record's canonical rate anchors on the Will County-side figure (the village's primary jurisdiction), confirm your specific target address's exact county and combined rate directly rather than assuming one villagewide figure.
Statewide, tornado-driven insurance cost pressure
