As a reminder, employers are required to file their copies of Form W-2’s and Form W-3 with the Social Security Administration by January 31st. Form 1099-Misc’s to report non-employee compensation to independent contractors, which needs to be filed with the IRS, are also due on this same date.
Also keep in mind that automatic extensions of time to file the W-2’s are not available, extensions are granted for very specific reasons only. You will need to fill out a form 8809 in order to apply for an extension:
