How this salary calculator works
Enter your pay, choose the period and review your tax profile. The result estimates annual deductions first, then divides net pay into equivalent pay periods. It is not a payslip or a tax return.
Tax year and assumptions
2026
- Includes federal income tax, employee FICA, automatic state income withholding for all 50 states and DC, and supported local income/payroll taxes. Excludes other employee state payroll insurance, disability, paid leave, unemployment contributions, health insurance and retirement deductions; actual take-home pay can be lower.
- Federal income tax is a 2026 annual standard-deduction estimate. State and local income taxes use current regular payroll withholding tables applied to a full year; they can differ materially from final annual tax liability and actual year-to-date paychecks.
- Full-year US-resident employee under 65, one job, no dependants or other income, living and working in the same state. Joint filing assumes one wage earner and no spouse income. Interstate, part-year and multiple-worksite profiles are not supported.
- Default state certificate allowances cover self and, for joint filing, spouse. Default self/spouse counts follow filing status until edited; custom elections are retained. Check the count against your state certificate. No additional withholding, special tax credits or itemized deductions are assumed.
- Local coverage is explicit: Maryland and Indiana counties, Pennsylvania PSD records, Michigan cities, supported Ohio municipalities and school districts, NYC/Yonkers and specified other cities. Unsupported local profiles stop calculation instead of silently using zero.
- Social Security wage cap is $184,500. Annual Additional Medicare thresholds depend on filing status; employers start its paycheck withholding above $200,000 for every status.
- California uses its 2026 withholding schedule, low-income exemption, standard deduction and DE-4 regular-allowance credits. Additional itemized-deduction allowances, disability insurance and other payroll contributions are separate from this income-tax formula.

Why can payroll differ?
Tax codes, family circumstances, credits, other income, employer benefits, contribution limits and rounding can change actual pay. Check the stated profile and official sources before using the estimate.
