How we calculate Idaho vs Florida
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 Idaho's and Florida's rules as modeled in our US calculator (Flat 5.30% vs No state income tax (0%)).
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 (~6.03% vs ~6.98%) and property tax (~0.5% vs ~0.78%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (101.7 vs 100.7, 100 = US average) and median household income ($70,800 vs $69,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Idaho → Florida relocation calculator.
