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.
Program is easy to use and will lead you thru everything. I have a moderat5ly complex return that requires added forms but have never felt I was missing anything.
Easy to use for the most part A little confusion with my downloaded 1099 from TD Ameritrade. First time I've had any trouble and have been using HRB software for more than 10 years.
