What to do if you have a missing W-2.

All W-2s are to be mailed out by January 31. If one is missing, you should take these steps: (1) Contact your current or former employer and verify whether your address is correct and request a resubmission of the W-2. (2) If not received in a week, call the IRS and provide the employer’s information, dates of employment and estimated wages. (3) File the return by April 15, 2015 and attach Form 4852 (substitute W-2) or file an extension. (4) File an amended return if your W-2 eventually shows up and differs from what you reported. If you will owe additional taxes it is better to file and pay by April 15 rather than file an extension.
