I used H&R Block software because, at one time, its more popular competitor would not allow you to load their program on two computers. In my case, I used one computer to complete the tax return software and another to print it. I have never looked back.
Reliability has decreased the past two or three years. This product used to be relatively error free. Now several updates are required to eliminate software bugs. It's disappointing to see an increase in software problems.
I've been using H&R Block Tax software for many years. It is so easy to use and I've never had any issues with filing my taxes. It also makes filing online so much easier.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
