Method and sources

Figures come from the same engine as our paycheck calculators: 2026 federal brackets and standard deduction, 2026 FICA, and 2025–2026 resident state schedules. City and county taxes, credits other than the Child Tax Credit, and nonresident rules are not modeled. Educational estimate, not tax advice.
