I've used H&R Block Tax Software since 2007, and have found it to be very comprehensive, accurate, and easy to use. I enter the information from my W-2s and 1099s, and the software does the rest. H&R Block Tax Software checks my Returns for errors and my Returns are always reliable and accurate when I file them. I wouldn't consider using anything else.
Pros: Easy to install, Easy to fix issues, Easy to prepare, Maximizes refund, Easy to import, Fast
I have used Block software for many years. It is easy to use and I have never had a problem. However, the cost for an additional state package should include the e-file charge.
