I find the H&R Block Deluxe tax software very thorough and easy to use. Only issue I had this year is that my entire initial return was somehow "lost" or inadvertently deleted and had to be redone all over again. However, I probably did a better job the second time around as my files were better organized. Like many such programs, it is always "garbage in, garbage out".
I've used this software for years and am always finding it accurate and easy to use. I checked a friends return, prepared by her CPA and found an error he made in her return, saving her a couple hundred dollars
I completed my returns but it took extra research and I found a couple of places that the program did things I had not directed. I noticed one only because a flag came up at the end and asked for another bit of information, when I hadn't even directed use of the form.
