Form W-4 allows employees to reflect certain deductions that affect federal income tax withholding during the year. These deductions are used only to adjust withholding and do not represent the final deductions claimed on an income tax return.

Deductions in the Withholding System

Deductions entered on Form W-4 are considered solely for withholding purposes. They are used to reduce the amount of income subject to withholding calculations applied to wages by the employer.

Form W-4 allows employees to account for certain types of income and adjustments that are not subject to regular wage withholding. This information affects how federal income tax withholding is applied through the payroll system.

Other Income Not Subject to Withholding

Form W-4 should be updated when an employee’s withholding information no longer reflects their current situation and federal income tax withholding needs to be recalculated. Updating the form allows the employer to apply withholding rules using the most current information provided by the employee.
