is one of these forms. Form W-4 provides employers the information they need to adequately set up a new employee’s filing status for payroll tax purposes. Form W-4 is published and updated by the U.S. Internal Revenue Service (IRS).
On Form W-4, employees can also declare the number of dependents, the tax credits and deductions they intend to claim. While this form is often used for new hires, employees can update the W-4 form they have on file with their employer whenever a change in filing status, dependents or other tax credits and deductions take place.
