How we calculate Kentucky vs North Carolina
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 Kentucky's and North Carolina's rules as modeled in our US calculator (Flat 3.50% vs Flat 3.99%).
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% vs ~7.1%) and property tax (~0.74% vs ~0.66%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (92.5 vs 96.6, 100 = US average) and median household income ($60,800 vs $68,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Kentucky → North Carolina relocation calculator.
