Excellent overall. Area for improvement would be more detailed year to year comparison for both finding potential errors in return and for planning next years income/deductions better. All the information is available it is just a matter of presenting it. Another area for improvement is to develop software that can detect when a deduction or income is used twice as this has been a problem that keeps coming up for me. I have had to find these mistakes but it would seem that a subroutine could help find more of these mistakes.
Error in printing routine, didn't recognize Adobe, latest version. Followed instructions to repair, and that didn't work either. So I had to do a work around. That's very annoying.
