* Due to IRS and state tax agency data sharing and validation requirements, you can only e-file a state income tax return while also e-filing a federal income tax return. This is not an eFile.com created policy, but a federally regulated one which all online tax filing websites have to adhere to. You can, however, prepare all 44 state income tax returns on eFile.com if you have already e-filed or filed your IRS return. View instructions on how you can ONLY prepare and file state income tax return(s). Only on eFile.com can you prepare and file or e-file unlimited state tax returns for one low price and not pay for each state return like you would do on H&R Block® vs. TurboTax®.
