I have used this software for several years. The Federal part of the program has performed flawlessly. The Alabama state software had a problem with one of the schedules which effected main tax form. I had to override the forms for corrrect submission. Also, the update on an iMac is not seamless.
I have been using H&R Block software for 4 years after switching from Turbo Tax. I find H&at Block easy to use and very dependable. It’s a great value.
