H&R Blocks program easily guides you through the tax preparation process. In addition it provides many helpful hints to aid in understanding the process and also will load last years data from previously filings.
I've used this for four years. Years 1 &2 great! 5 stars. But last year and this year I had trouble. Last year, 2018 it did not do something right in the interview questions and IRS contacted me later and I owed some more taxes because of some unreported income. I review my return and agreed with IRS. But, that income WAS included in the interview questions of H&R Block's program. And this year, 2019, at the end of the program it says I owe a significant amount of more taxes than I and my wife had paid (over 20% more). She is W-2 income, I am self-employed and send estimated quarterly taxes in. I had to search through the forms in this program and manually edit them before I could send in my return. I found that somehow, and I don't know how, but somehow, this program recorded income from one of my businesses twice in two different locations!
