Thanks to Maron Resur at SNO for the detective work:
I visited all the external tax prep sites listed at irs.gov, and I found out a few things. Of the sites that listed their system requirements, these 3 appeared to be compatible with the current configuration of our public computers:
· These sites require IE 5.0 or 5.5 minimum (we have IE 6), and cookies will need to be enabled (manually, by us? Possibly).
· Also, all sites have some forms they don’t support (usually a list is accessible from the main page), or are only free if you are under a certain income level.
· Many of the companies on irs.gov did not list their system requirements (including H & R Block).
· Turbo Tax is absolutely not compatible with our current set up.
When you choose E-File or Free File from irs.gov, there are 2 options: “I will choose a company” or “Help me choose a company” (the latter always seems to pick H & R Block). The former option is where I found the list of sites that I investigated.
