What is the Form W-3?
The Form W-3 is a transmittal form used by employers in the United States to submit the annual wage and tax information of employees to the Social Security Administration (SSA). It accompanies Form W-2, which reports individual employees’ earnings, taxes withheld, and other compensation details. The Form W-3 summarizes the total wages, tips, and other compensation reported on all W-2 forms filed by an employer for the year. Employers must file the Form W-3 with the SSA by the end of January each year, ensuring that it matches the total amounts reported on the accompanying W-2 forms.
