How we calculate Missouri vs Illinois

Tax engine. Federal income tax uses 2026 IRS brackets and the standard deduction for a single filer. FICA includes Social Security and Medicare employee shares. State income tax applies Missouri's and Illinois's rules as modeled in our US calculator (Progressive (top 4.70%) vs Flat 4.95%).

What's included. Wage income only — no capital gains, self-employment tax, itemized deductions, credits, or local city wage taxes (e.g. NYC) unless noted. Sales tax (~8.44% vs ~8.98%) and property tax (~0.89% vs ~1.88%) are context metrics, not subtracted from the take-home ladder.

Cost of living. COL indexes (88.6 vs 95.1, 100 = US average) and median household income ($67,800 vs $77,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Missouri → Illinois relocation calculator.
