I'm concerned with the privacy/security issues of having my tax return, which contains a lot of sensitive data, stored on this site (as it needs to be, if they want to, for example, import my last year's data). If I use a tax program that runs on my machine, my tax return only needs to be stored momentarily by the service provider, while it's being transmitted to the IRS. Also, despite being called "Free Tax Software", it's not really free, since most people in the U.S. also need to file a state tax return, and that costs $14.99.
