I've been using H&RBlock's tax software for the past 17 years. Each year it gets incrementally better. It is a real time saver and is very easy to use. I highly recommend it.
I've used H&R Block software for 7 or 8 years (ever since the other guys tried to charge extra for doing more than one return) and it's been invaluable. It is easy to use, accurate, and fast. I would have given it a 5-star rating except for a small glitch this year: I filled out two 1099-INT's in advance, because I knew how much interest I had earned, before they were actually available at the end of January. Later I downloaded 1099-DIV and 1099-MISC from the same brokerage house, and didn't realize the same 1099-INTs were also downloaded. I had two identical copies of each one, but H&R Block didn't catch that. I found them later myself, when going over the printed return before I filed it.
Pros: Easy to prepare, Easy to import documents, Fast
I've used H & R Block tax software since the mid ninety's when I purchased my first tower computer. I was happy with the program then and see no reason to change today.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
Interview process for fed and state went well as did direct interaction with forms. Help seemed a little better this year. Inconsistent ability to find out where numbers came from and ridiculously high cost to electronically file for state, so I didn't.
