I've updated my annual H&R Block At Home Tax Software Versions, Features and Prices for tax year 2013, and Block is once again offering a good value for the cost with Federal e-File and Worry-free Audit Support being included with each version, priced from free to $80. H&R Block covers all popular hardware platforms with tax software and apps for Windows, Mac, Android, iPhone, iPad and online tax prep. State returns are extra and are pricey, but you could use H&R Block At Home for your federal return and then enter information from that return into free tax software offered by most states.
My favorite H&R Block tax software product is the Best of Both package, which combines online tax software so you can complete your return yourself with complete access to a tax professional all year round. The tax pro looks over your return before it's filed, all for $80.
