I worked with my last employer until early Dec of 2005. I then had a baby and did not return to work. Recently, I got a summary from social security that included some income for 2006. I was susprised because I haven't worked since I had the baby, so I called to ask where it was reported to have come from. They told me that it was from my last employer, so I called and asked for a w-2. The form reports an income of $3,562. The problem is, I don't recall ever receiving that, and now that it's 2007, my income tax return has been filed for almost a year and that income was not included. I would like to receive some detail as to what that sum is composed of. Is my former employer obligated to provide me with proof of that income if I request it? Any help is greatly appreciated.
