The software is very reliable. My only complaint is the high additional cost if we file in two states. I moved from one state to another and the cost to buy for a second state is too high.
I've been using H&R Block Premium software to complete my annual tax return since 2012. It greatly assists in filing your tax return, making it easy to understand and walks your right through all of the paperwork and forms you need, especially if you're a small business owner. It's very user friendly. I've filed successfully returns for the past 10 years using H&R Block products. I highly recommend this tax software package.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
We used HR Block in the past, and it is good for just the basic stuff, but when you have challenging issues or a little more complicated tax, then HR Block is not a goof option!
