Long time user and I have never had any issues with the software nor with the validity of the tax return.
Once when I upgraded to a new computer I called the technical support folks for help with getting the prior versions of the software on my new computer and it went seamlessly.
As usual, the software worked well for the fairly limited returns that I prepare for myself and family members. It handles Schedules A, B, C, and D quite well. I love the ease of state prep, as the software does necessary adjustments.
I ordered the software and it would not download to my aunt's system, she had bought software to do her family, we even called tech support that couldn't help us
I have been using H&R Block software for at least 25 years and find it to be extremely accurate and relatively simple to use. It is a great program with fabulous support and I would feel lost without it at tax time.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
