I started using H&R Block software several years ago after using another brand of software. I love how easy it is to work with. They walk you through every area of your return to make sure that you get every deduction you are entitled to.
Been using it for years. Always worked and generally easy to use. Didn't like having to get some immediate answers to questions and having to pay for the answers.
Our family has been using H&R Block Deluxe for the last several years. We appreciate that it's very easy to use and imports the prior year's data into the current year's form so you don't have to retype everything. Furthermore, if you need to change or update any information, it's very easy. I would suggest organizing all your documents beforehand (i.e. W2s, 1099s, etc.) for an even speedier process. Filling out our federal return takes less than an hour.
Pros: Easy to prepare, Easy to import documents, Fast
