I've been using H&R Block Software for more years than I can remember. It's excellent and user-friendly. My only request might be some more detailed help documentation on certain topics, but otherwise, I highly recommend it.
I completed my Federal return but was unable to start a state return. Had to use the help desk. They had me wipe off the download I had started with and download the latest version. Then everything worked very well. This is the 2nd time in 3 years I have had problems with the early downloads.
I have used H&R Block for several years. It is easy to work with and I get great results. The software leaves no stone unturned regarding any available tax deduction.
