The deadline for remitting Form W-2 and Form W-3 to the Social Security Administration is Jan. 31, 2019.
You must furnish the W-2 to your employees by Jan. 31. You will meet this requirement if the form is properly addressed and mailed on or before the due date. If you receive a form back in the mail because it was undeliverable, keep it for 4 years. However, you do not need to keep the W-2 if it can be produced electronically through Apr. 15 of the fourth year after the year at issue.
