I have been using this for years and too lazy to learn another one, but certainly the software is getting clumsier. It gets the job done, and I have never been audited, so there's that.
I have used H&R TaxCut for over 20 years and have found it to be very accurate and helpful in making sure I have done my taxes correctly and gotten every deduction I am entitled to. It makes doing our taxes much easier than when I used to do everything by hand using the IRS handbook. TaxCut is the greatest.
H&R Block makes doing taxes much easier. I proceed through the interview with confidence that my return will be accurate. When I find I need to change an entry, the program recalculates immediately, so I always know where I stand. E-filing is easy and fast. It's convenient to check the status of my return once e-filed.
