This guarantee is good for the lifetime of your personal, individual tax return, which Intuit defines as seven years from the date you filed it with TurboTax. 100% Accurate Calculations Guarantee – Individual Returns: If you pay an IRS or state penalty or interest because of a TurboTax calculation error, we'll pay you the penalty and interest.(By contrast, the online version charges $36.99 for the state software add-on, but it includes one state e-File.) My suggestion is to simply print out your return, mail it in for the cost of a stamp and envelope, and pocket the savings. Note when comparing prices: If the download/CD version only says State download is included and not explicitly State e-File, then you can complete a state return, but the State e-File will be an additional cost of $19.99 per return.
