I am in need of money and missing one W-2. Where can I go or, who can I call, that can help me get this info. Without having to wait for it to get here. Thanks

Employers must mail W2 by Feb 2, 2007. If you do not receive it by Feb 15, then you can call IRS.
You may be able to file without W2. However, you should wait till you get all the Forms like W2s and 1099s. If you file based on last pay slip, you may have to file amended tax return if there is any different figure in W2 or 1099.
