How we calculate California vs South Dakota

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 California's and South Dakota's rules as modeled in our US calculator (Progressive (top 13.30%) 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 (~9.03% vs ~6.11%) and property tax (~0.7% vs ~1%) are context metrics, not subtracted from the take-home ladder.

Cost of living. COL indexes (140.5 vs 94.1, 100 = US average) and median household income ($93,500 vs $69,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the California → South Dakota relocation calculator.
