I am completing my student aid form at work and I need to see what was in line 37 of my taxes from year 2007. Can I find it on-line?

IRS does not put it online.

How do I get a copy of my w2 form from 2007

Line 37 is your Adjusted Gross Income. If you don't have a copy of your 2007 income tax, you can order a copy of a "transript" from the IRS for freem which will include this information. See: Tax Topics - Topic 156 Copy of Your Tax Return – How to Get One
