How we calculate Iowa vs Connecticut
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 Iowa's and Connecticut's rules as modeled in our US calculator (Flat 3.80% vs Progressive (top 6.99%)).
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 (~6.94% vs ~6.35%) and property tax (~1.33% vs ~1.54%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (88.6 vs 114.2, 100 = US average) and median household income ($72,800 vs $86,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Iowa → Connecticut relocation calculator.
