When using TurboTax Business, your TurboTax Deluxe 2017 data is kept secure online in a cloud server managed by Intuit, the company that owns TurboTax. This helps protect your information from hackers who might otherwise access it, and also ensures that your work is saved even if your computer crashes. This is in contrast to downloadable tax programs that must be stored on your own computer and are therefore at a greater risk of hacking.
