How we calculate Connecticut vs Massachusetts
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 Connecticut's and Massachusetts's rules as modeled in our US calculator (Progressive (top 6.99%) vs Flat 5%).
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 (~6.35% vs ~6.25%) and property tax (~1.54% vs ~1%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (114.2 vs 147.8, 100 = US average) and median household income ($86,800 vs $97,200) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Connecticut → Massachusetts relocation calculator.
