This calculator estimates employee paycheck withholding using the tax year, pay date and details you provide. Your employer’s rounding, benefit plans, withholding elections, year-to-date wages and work or residence jurisdictions may change your actual paycheck. Withholding is not your final tax liability. This is not tax, legal or payroll advice.
Why your real check may differ
- Your employer may round withholding to whole dollars or use the wage-bracket tables instead of the percentage method.
- Benefits may be taxed differently by your plan (for example, after-tax premiums), or start and stop at different times.
- Year-to-date wages, a mid-year W-4 change, or a second job change withholding on a specific check.
- Local taxes depend on exact addresses, school districts and residency, which a calculator can only approximate.
- Rules can change during the year. Results use the 2026 rules shown with each result and the date they were last verified.
