How we calculate Arizona vs Washington

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 Arizona's and Washington's rules as modeled in our US calculator (Flat 2.50% 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 (~8.54% vs ~9.57%) and property tax (~0.48% vs ~0.75%) are context metrics, not subtracted from the take-home ladder.

Cost of living. COL indexes (107.6 vs 114.6, 100 = US average) and median household income ($71,200 vs $90,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Arizona → Washington relocation calculator.
