Have used this tax prep software for nine years now. Info from prior year transfer easily and updating for current year is easy. My refund showed up in my checking account in less than a week from date of filing.
The most useful feature to me is that last year's information is imported for you and then all you have to do is enter your new data for the current year!
We have used the program for years and have always been happy with it. There is very little fun in the tax process, but H & R Block minimizesl the difficulty of participating.
Pros: Easy to prepare, Easy to import documents, Fast
