As you know, you need your W-2 in hand if you are going to file your individual tax return.
While this is not usually a problem, some people misplace it for one reason or the next and find themselves in trouble.
Employers usually have until early February to provide this form to all qualified employees.
But if you are saying I have "yet to receive my W-2," then you should follow these steps:

1. Get in touch with your employer.
   Before you jump the gun you should contact your employer and ask them when it was mailed.
   If it was mailed there is a chance that it could have been returned due to a wrong address.
   Once you speak with your employer be sure to leave enough time for them to reissue a replacement.
   
2. If you do not receive your W-2 by mid-February, it is time to get in touch with the IRS.
   Before you call, have the following information on hand: the name and address of your employer; your name, address, and social security number; an estimate of how long you have worked for your employer, as well as what you earned the past year.
   You can base this information on your final pay stub of the previous year.
   
3. File your return.
   Even if you do not receive your W-2 in time you still need to file your return.
   To do this, you can use Form 4852, Substitute for Form W-2, Wage, and Tax Statement.
   Of course, your information may not be 100 percent accurate because you will have to estimate both your withholding and income.
   Since this information may not be 100 percent accurate, processing could take a bit longer.
   
4. When you receive your W-2 you will want to file Form 1040X, Amended U.
   S.
   Individual Income Tax Return.
   If the information on your W-2 is different than what you reported on Form 4852, then this is a necessary step.
   

Even if you are missing your W-2, you can still file your final individual tax return.
