I've been using the H R Block tax software for approx the last 10 years. It has been flawless. Easy to use. It won't allow you to make a mistake, omission or miscalculation. It has been used for calculating other family members taxes as well. Also no problems from the IRS once the taxes were filed. Really could not be any better.
I have used this product for 10+ years. It is easy to use for my returns and has never had an error or issue. It's year to year transition saves a lot of time.
The software is fairly easy to use--as easy as the federal income tax can be to understand; but, that being said, it does have a few hard-to-understand places that it takes time and study to determine the meaning of.
I used the Mac version for the first time, and there was no way to overridge fields in Schedule C which I've done for years with my own lists of items using the Windows version. Worse, e-filing failed and messed up my entire deal. I didn't see the message that it had failed until I'd already sent in my check. I had to take another trip to the office and print out the forms and send them separately. It seemingly turned out okay, but the reason for the failed e-file was wrong. I'd included the proper data and it said I hadn't. By far my most disappointing year with HRB and I've used it for two decades now.
After I have compiled complete and accurate tax input data (the hard part) H&R Block software makes the rest of the tax preparation process quite easy. I couldn't ask for more than that. I no longer dread tax filing season with the knowledge that H&R is going to make it easier for me and also keep me out of trouble by eliminating typical filing mistakes.
Will never buy again. Multiple technical errors with downloaded program. They knew about the program problem and had me download a "better" one. Got error messages from IRS. Still waiting for my refund 3 1/2 months later.
Cons: Time consuming, Hard to prepare, Hard to import documents
