Historically, this software has worked well for me. This year, I received an error when I submitted my Federal return via e-file. The error was very unhelpful, simply stating that "we can't e-file your return right now" and to call a 877 number to continue the filing process. This was all via email.
Pros: Easy to prepare, Easy to import documents, Fast
H & R Block's Tax software program is very simple to use. The first time requires all the info to be inputted, next time around it's automatically transferred for you. The questions are simple and straight forward and all the forms are filled out for you. The program does a review of your return to check for audit "Red Flags" and if you may have left out information. H & R Block's Tax Prep Program is easy to use and costs less than "the other guy's" while giving you the same result.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
HR Block deluxe software worked well enough. It experienced several updates, during the season, but that may reflect changing IRS rules. Updates went smooth enough. It listed what forms were "final" so that you new tax rules won't change..
