How we calculate Massachusetts 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 Massachusetts's and Washington's rules as modeled in our US calculator (Flat 5% 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 (~6.25% vs ~9.57%) and property tax (~1% vs ~0.75%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (147.8 vs 114.6, 100 = US average) and median household income ($97,200 vs $90,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Massachusetts → Washington relocation calculator.
