TurboTax is free if you use the Free online edition and do not upgrade to any of the other editions such as Plus, Deluxe, Premier or Self-Employed. The Free edition is only for fairly simple tax returns and only supports IRS Forms 1040EZ and 1040A. If you have tax data that cannot be entered on a 1040EZ or 1040A the program requests that you upgrade to higher edition which is not free.
