Flawed - does not compute new child care credit properly and caused us to owe money. They will do nothing helpful to fix the problem. Took us 6 calls to get to the right department.
Easy to use, keep track of your income/taxes, feel comfortable with your filing as Block software walks you through the filing, asking proper questions directing you to supply accurate answers reducing the IRS flags that would generate an audit.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
In general, the software was easy to use. There was one drawback: We had made estimated payments on the State Income Tax, and it was difficult to find where this data should have been entered into the program. We eventually figured it out. but it seemed that the process of figuring this out could have been a bit easier for a "duffer" user like myself.
I love the software and use it for multiple returns each year. It is very intuitive. It handles complex returns. It is easy to move about to different parts of the return.
