I can tell you from personal experience if you have to file an update to your return for anything other than the current year you are going to hate the online cloud based version. I had to file an update for the previous year and the online version had no provision to download previous year's version. I had to buy the download version for that year and start completely over from scratch to duplicate my return in the software based on a saved PDF copy. It was a huge pain. If you have the download or DVD you can just load it up and go.
