How we calculate Wisconsin vs Idaho
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 Wisconsin's and Idaho's rules as modeled in our US calculator (Progressive (top 7.65%) vs Flat 5.30%).
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 (~5.72% vs ~6.03%) and property tax (~1.32% vs ~0.5%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (97.4 vs 101.7, 100 = US average) and median household income ($74,800 vs $70,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Wisconsin → Idaho relocation calculator.
