How we calculate South Dakota vs New Jersey

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 South Dakota's and New Jersey's rules as modeled in our US calculator (No state income tax (0%) vs Progressive (top 10.75%)).

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 (~6.11% vs ~6.6%) and property tax (~1% vs ~1.88%) are context metrics, not subtracted from the take-home ladder.

Cost of living. COL indexes (94.1 vs 118.8, 100 = US average) and median household income ($69,800 vs $98,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the South Dakota → New Jersey relocation calculator.
