Excellent. Have used for years. Didn't get a 5 star because I don't understand why for two seemingly identical Arkansas returns one requires copies of the 1099-Rs attached and the other doesn't even though both people have 1099-Rs.
I used the SW for my simple tax return process. I have W-2 and HSA and applied the standard deduction amount. It's easy to install on my MAC and follow all steps. Also it has a great value.
Pros: Easy to prepare, Easy to import documents, Fast
I have always completed my own taxes. I've been using Tax Cut/H&R Block for as long as I can remember, and I've had no problems other than my own, occasional mistakes. I can't imagine ever using anything else.
