I've been using this program since 2003, so this is my 20th year with the TaxCut software. Honestly, it's garbage, and I hate it. It's not intuitive, and the explanations are quite frequently inadequate. The program does not import prior year returns consistently either (go read other reviews about this!), so you run the risk of having to start from scratch on an annual basis. I've had to do this more than once! It's no big deal if you're just doing a 1040-A or something simple like that, but if you're a small business owner like I am, it's a major hassle. Don't ask me why I keep giving them my money year after year.
I buy a number of tax prep software, then compare every year. For the last 4 years H&R Block Premium and Business has done the best job with helping me get the largest Federal and State Return, the Ease of Use and detailed explanations help!
It is a well-designed and serviceable product. I occasionally had difficulty getting back to specific issues but I believe that was due to the "dotage factor" rather than a design error in the program.
