Financial
Tax Withholding Calculator
Estimate how much federal income tax should be withheld from each paycheck given your annual gross income, filing status, allowances, additional deductions, and any extra withholding you've requested. Use it to roughly check whether your current paycheck withholding is in the right ballpark or whether you should update your W-4.
Fill in the required fields to see your result.
Taxes
Income Tax Calculator
Calculate income tax owed by applying a flat tax rate to total income β a simplified shortcut for estimating tax burden in flat-rate jurisdictions or for back-of-envelope marginal-rate math. Use it for quick gut-checks; for real US federal tax which uses progressive brackets, use a dedicated tax-bracket calculator instead.
