For employees, withholding is the amount of federal income tax withheld from your paycheck. The amount of income tax your employer withholds from your regular pay depends on two things:
- The amount you earn.
- The information you give your employer on Form W–4.
For help with your withholding, you may use the Tax Withholding Estimator. The Tax Withholding Estimator compares your income tax estimate to your current tax withholding and can help you decide if you need to change your withholding with your employer.
