I've been using this software for four years. Just update your yearly information and it calculates everything. I even got tax brakes on things I didn't know about.
I have been using the H&R Block tax software for the past 15 years plus and I have nothing but the best experience possible.Their software is easy to use, and there are help screens for each section with explainations.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
I have used H&R Block Deluxe for many years and always find it easy to use and comprehensive. That said, there are some codes on Schedule K-1 that this software does not tell me how to treat. I wish it would handle these as digging into the IRS docs is confusing and time consuming.
I had an issue with a calculation on one form and it was never fixed through any of the updates. When I called they kept telling me I can't eFile because of a different form that was never in my tax return to begin with. Epic Fail this year.
