Credit karma lets you file both federal and state for free . CreditKarma's filing service is pretty new, so there are lots of edge cases they don't handle well or at all (for example the UI to enter stock trades is awful). I put my numbers into TurboTax and CreditKarma to make sure they match for validation, then filed with CreditKarma. You give them a lot of data about you that they then use to sell you insurance and loans and so on, but I actually find their services useful so I consider that a fair trade.
