What is W-4 Form?

W-4 Form is a tax form used by employees in the United States to determine the amount of federal income tax to withhold from their paycheck. The form collects information about the employee’s filing status, dependents, and other tax adjustments, which helps employers calculate the correct withholding amount based on the employee’s personal tax situation. Employees must submit a completed W-4 Form to their employer at the start of employment or when any changes to their tax situation occur.
