Software is comprehensive but easy to use and intuitive. Only problem is that as I am now located outside the USA I was not able to purchase additional state tax packages and e-file them as your payment system does not accept non-US addresses (even for US bank cards). This is a major issue which stops your software from being used by the many non-US based tax filers.
Program has improved markedly in the last year. I use for a complex return involving two rental properties, (one as business, one as vacation rental with personal use), extensive securities trading, gas well, and complex charitable donations of "other than cash" transactions. For first time the program removed "glitches" that had prevented electronic filing the past and permitted full electronic filing of both state and federal returns. Still some problems with use of "Deduction Pro" in terms of getting printouts of Deduction Pro data separate from actual IRS "other than cash" donations.
