I have been using H&R Block software to compute and submit federal taxes for 7 years for my wife and I, my mother, and my kids. Where I live in Florida we have no income tax but I have also been using the state of Utah version to help my daughter compute her state taxes as well. H&R Block software is inexpensive, a great value, easy and quick to use, and provides accurate and reliable returns. I highly recommend it!
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
Had a little trouble with the downloading instructions, probably due to my computer's slow speed. Once started everything was easy and self explanatory. Great program!
