Homonym: W-4 (Withholding)
A W-4 form is an official document used by employees in the United States to inform their employer about their tax withholding preferences. By filling out this form, employees can indicate how much federal income tax should be withheld from their paychecks, which helps ensure they pay the correct amount of taxes throughout the year.
The W-4 form takes into account various factors, such as marital status and the number of dependents, which can affect tax liability. It is important for employees to review and update their W-4 whenever they experience significant life changes, such as marriage, divorce, or the birth of a child, to avoid under- or over-withholding.
