User Reviews

  • Good overall but need a little better support.
  • simple Q&A design (fill in blanks, atypical from std forms) does NOT have all states, just 6 - 7 or so. ok for just federal 1040, but limited to certain forms, good for starter taxpayers, say, teens and older folks (NOT for business) great for initial double-check on 1040 though
  • Great help with my taxes! UI not there enough that I'd say it was easy starting from 0. What I had to do is look at my taxes from last year (done by H&R Block) and figure out everywhere in Open Tax Solver that I needed to have data filled in. Using this method I was able to get my taxes prepared easily enough. Also missing 'Form 8995 Qualified Business Income Deduction Simplified Computation' which I needed.
  • Really want to like this app but it isn't user friendly and the UI is poor. I think if a designer were to help out this thing could be great.
