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.
Financial
Tax Bracket Calculator
Estimate the percentage of your gross income that remains taxable after applying deductions. Use it as a rough proxy for tax exposure β though it does not compute the actual US federal income tax (which is progressive across brackets, not a single flat rate).
