Really curious since I did not try HRB myself:
If you had Schedule C income and it was "non-passive" (i.e., you actively participated in the biz), can you let us know if Form 8960 Line 17 "Net investment income tax for individuals" (NIIT) with HRB is a higher amount than with TT? Also, were Lines 4a and 4b different for HRB vs. TT?
Based on a bunch of posts from several days ago, it sure sounded like HRB wasn't subtracting "non-passive" Schedule C income on Line 4b. And if that's the case, they'd pay the 3.8% NIIT on income that is NOT subject to NIIT.
