IRS form w2

Continuing our tax theme, we will run a series detailing some of the most common tax forms you have received, or will be receiving, in the next few weeks. 

First up is the W2.  All information is for the 2007 tax year.  Forms will sometimes change from year to year, so check the web site for the latest information.

Form W2 is completed by your employer, and the information it contains is reported to the IRS.  Your employer is required to provide you a copy of your W2 before January 31. 

A W2 basically reports wages paid to you by your employer throughout the year.  Additionally, it shows all taxes that were withheld from your earnings. 

Form W2 contains a series of lettered and numbered boxes.  You can click the image above to view a larger image as we go along.
