Can I file somebody else’s taxes with my TurboTax account?

Each tax return requires a separate account with a separate username and password, but you can use the same email address for all of them. Never start another return by going back and overwriting everything in the return you just filed. This will replace your info, which means you won't be able to retrieve your return later.

You might want to switch to the TurboTax CD/Download software to save money

• Unless the additional return/s you want to file in TurboTax Online are simple returns and can be filed using the Free Edition, there is a charge for each additional return filed in TurboTax Online.
• On the other hand, the TurboTax CD/Download software lets you file up to 5 federal returns at no additional cost.

If you still want to start another return in TurboTax Online, here’s what to do:

1. Sign out of TurboTax Online.
2. Select the TurboTax Online product you want to use for the second return and proceed.
3. On the Create your account screen, set up a new user ID for the second return.
   • You can reuse your email address if you want to receive e-file notifications for the second return.
   • Up to 5 accounts can be tied to the same email address.
4. After you've created the new account, you can start working on the second return.
5. If you can't create a new account because your web browser automatically logs you into your old account, you may need to clear your browser history, cache and cookies.

Can I file somebody elses taxes with my Turbo Tax acc

@uanita 

NO...your tax account is only for you (or you and spouse if MFJ)

For any "Online" software users, they need to create a separate tax account for each person (or each couple when filing MFJ).

Thus, if helping aging parents, or other family members, you must create a separate account (new UserID & Pwd) for each one.   AND keep track of whose is whose.

Only 5 can be tied to any one email address.....thus do NOT use an email address for the UserID

What if you already started to overwrite the info before reading your advise?

I already printed my returns and downloaded copies.

Should I recreate it through Turbo Tax?

.... and they have been eFiled and accepted by Fed and State.

Yes, you should modify your TurboTax account info to match the return(s) you filed and were accepted.   Otherwise, your tax history will not match what is on file with the IRS.  @1cyrice

I think I made this mistake last year as well.  The IRS said they never received my eFiled 2020 Tax Returns.  I think I started my daughter's taxes by overwriting mine even before mine was "accepted" by the IRS.  

It is not recommended to do this. It's a good idea to have separate accounts.
