How we calculate Pennsylvania 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 Pennsylvania's and Idaho's rules as modeled in our US calculator (Flat 3.07% 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 (~6.34% vs ~6.03%) and property tax (~1.26% vs ~0.5%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (96.2 vs 101.7, 100 = US average) and median household income ($72,800 vs $70,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Pennsylvania → Idaho relocation calculator.
