Get your taxes done using TurboTax

With download, you can make a copy of your return and then manipulate it all year as a preliminary return for the next year.
Online is usually cheaper, but this advantage is wiped out if you have to upgrade. You can do all types of returns in the lower download versions.; e.g. you  can do a self employed schedule C in Deluxe.
An older computer may not have the capacity to handle a download.
