I've been using H&R Block's tax software for years. Rarely have I had any issues. When something does come up, their customer service staff has always been able to guide me through to the solution. Very helpful and friendly.
Pros: Easy to prepare, Easy to import documents, Fast
Hard to use compared to TurboTax. Fonts too small. Instructions not clear regarding retirement 1099s and IRAs and 401ks. Had to do a lot of Dick Tracy detective work with IRS publications due to crappy software.
Very easy to use, accurate, and does most of the work for you. I have used H&H Block for as long as it has been on the market. I will not do my taxes any other way.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
I wasn't able to load last year's taxes the usual way. I was able to load a pdf file. I also wasn't able to install this year's pdf creation app on one specific laptop but was able to do so on another using same windows 10 os.
