Dear Sir or Madam,

How can I request a free copy of my filed taxes for
Year 2004, 2007 and 2008?

Also, requesting copies of my 2004 W2 from
A prior employer?

Tax Topics - Topic 156 Copy of Your Tax Return – How to Get One

An exact copy of your tax form is not free. Transcripts are but don't go back that far. So this isn't exactly what you want, but there's nothing I can do about that.

The only other place you might get it is anyone you gave a copy to, like an accountant who did them for you.

As for the prior employer, did you try calling them? You can get that with a copy of the tax return, but that'll cost you.
