Of course, there is one detail involved with buying the desktop software.
You are in CA, and she in IL..
Exactly who is going to prepare those tax returns?
If you are preparing both using desktop software on your own personal computer(s) in your location/possession...then probably OK.
But if you plan on sharing your desktop software with her, you in CA and plan to send her the same purchased copy to install in IL, then that's a no-no. You can only install a purchased copy of the desktop software on computers that one person owns.
