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.
Confusing. Navigation is terrible. It seems everytime I go back to change anything it makes me walk through all the previous steps. Finally figured out how to avoid that. The GUI looks like it's from the late 90's. I'm pretty sure it did not calculate the tax right. For testing I put in a high number as income and it still said I didn't owe any tax. I ended up printing it out and doing my taxes manually comparing the results from this software. I'll prob get a letter from the IRS soon. Nice thing is that I get +5% refund card to Amazon. A lot of the core functionality seems to be there but the software needs some serious help from a users perspective.
Pros: Easy to install
Cons: Time consuming, Hard to fix issues, Hard to prepare
