I've used the Block software for a number of years and have also used other software packages. Data transfers easily from one year to another and from outside sources. Basic information is automatically injected and formatting is continually checked. The accuracy check at the end is very helpful. My one issue with this package and all of the others concerns the "Help" file. Its not always as complete as I need and it doesn't always answer my questions. Especially when the politicians are making changes to the tax laws and my question is, "why is this different?"
Pros: Easy to prepare, Easy to import documents, Fast
Filing electronically is prevented if the IRS previous year’s AGI has not been updated. There should be an alternate way for the H&R software to bypass this criteria. Very frustrating.
