Form W-4. Employee's Withholding Certificate

Form W-4, issued by the U.S. Department of the Treasury's Internal Revenue Service, is used by employees to inform their employers of the correct amount of federal income tax to withhold from their paychecks. This form ensures that the correct tax amount is deducted to avoid overpaying or underpaying taxes. Employees need to complete a new Form W-4 each year or when their personal or financial situation changes, such as getting married, having a child, or starting a new job. Properly filling out Form W-4 helps in managing tax liabilities effectively and ensuring compliance with federal tax regulations.
