What page do I go to find a copy of my past income taxes?

Answer 1

If you filed your tax return using a professional tax preparer, then you can get a copy of your records from him/her.

Otherwise, as long as you filed your tax return with the IRS, you can request a photocopy or a computer transcript (a line-by-line listing) of the information on your filed tax return. Photocopies and transcripts are free from the IRS. If you need an actual copy (not a photocopy), then you must complete Form 4506 and pay a $39 fee for your filed tax return and all related tax information, such as your Form W-2.
