I used to never fill out the registration screen. But I finally got tired of it so I filled it out. I never get any advertisements or anything. I assume it's so they can notify me if there is a problem with the program.
I opened an older program to see the registration screen. At the top it says to keep you up to date with tax law changes. At the bottom it says we will not rent, sell or share your personal information with anyone outside of Intuit for their marketing use. And there is a link if you do not want to receive marketing materials.
