Illinois has lost population every year since 2013, and Missouri has been a top destination for outbound Illinois residents. The I-55 corridor from Chicago to St. Louis carries a steady stream of Midwest transplants — and the state line crossing near Alton and Grafton creates an unusual pattern where some Illinois residents live just miles from a more tax-friendly state they can relocate to relatively easily.

Moving from Illinois to Missouri: FAQ.
Is the property tax savings really the main reason?
Yes for homeowners. IL 2.07% effective vs MO 0.88% — on $300K home, save $3,570/year. Over 10 years of ownership, $36K+. For longer holds, savings compound. Many Illinois homeowners describe property tax as the single biggest financial pain point — MO offers genuine relief. For renters, savings smaller.
Missouri income tax progressive vs IL flat — which better?
Depends on income. Low earners (under $40K taxable) pay less in MO due to graduated brackets starting at 2%. Middle earners ($50-100K) roughly wash. High earners (>$200K) actually slightly favor IL's flat 4.95% vs MO's 4.95% top (small brackets). Property tax savings dwarf income tax comparison for most households.
St. Louis vs Kansas City for IL transplants?
St. Louis closer (3 hr) for Chicago family visits; has Washington U medical, Boeing Defense, urban culture. Kansas City farther (8 hr) but growing tech, Cerner/Oracle Health, KC Chiefs culture, BBQ scene. KC suburbs (Overland Park, Leawood on KS side) highly rated. Match to career and family priorities.
