About this calculator
Tax withholding is the amount an employer sends to the IRS from each paycheck toward an employee’s expected federal tax bill.
Basic formula: Estimated annual withholding = withholding per paycheck x pay periods.
This free tool provides an estimate from the values you enter so you can compare scenarios and make more informed planning decisions. Results can differ from employer payroll systems, tax filings, lender calculations, or professional advice.
For paycheck and tax estimates, review our calculation methodology and official IRS and SSA sources. Tax rules and limits can change, so verify important decisions with the relevant authority or a qualified professional.
