Can I prepare EZ returns for our special needs adult son who lives with us on my account - or do I need to open a separate tax return account to file his returns?

When using the online versions, you will have to start a new account with a new unique user ID for another tax return. The online editions are only good for completing one tax return per account and user ID.

If you're using the TurboTax CD\Download, you just need to start a new tax return and enter your son's information.
