What You Need to Know about Form W-4
- An employee must complete the form at hire before the first paycheck is provided.
- Employees may change the amounts on their W-4 form at any time and as often as they wish.
- The most current W-4 must be signed by the employee and kept in the employee's payroll folder to verify the amount of federal income tax withholding.
- Many U.S. states use their own variation of the W-4 form to record state withholding amounts.
You may not give advice to new employees on filling out the form. If an employee is having difficulty completing the W-4 form, you might want to direct the person to this IRS article about Calculating Your Withholding Allowance.
