How to read this resultShow
Tax calculators use 2026 federal tables where available, best-known 2025 state tables, and simplified assumptions. Credits, deductions, state rules, timing, and special situations can change the final tax outcome.
Federal tax brackets, standard deductions, withholding tables, FICA wage base, and dependent credits use 2026 official-source data. State tables apply 2026 enacted rate cuts (e.g. IN, KY, MS, MT, NE, NC, OH); other states use best-known 2025 data until refreshed.
Smart next steps
- Right-size withholding so your refund or bill lands near zero.
- Revisit when income, filing status, or major deductions change.
