It's a very easy program to use and I have done so for 14 years. HOwever, occasionally it is difficult to find a particular issue or answer a certain question. All in all, I am satisfied but I wish some of the input questions covered more specific cases.
Works very well for simple returns. There are some more complex forms such as schedule E for partnerships that are weakly supported. For my state return (AZ) there are missing forms that prevent e-file and thus require paper returns to be filed.
