Should I create a new TurboTax account each year?
No! You should stick with the same account year over year. That way we can automatically transfer your info over, and it greatly simplifies access to your prior-year returns because they're all under the same account.
The only time you should create another TurboTax account is if you're doing someone else's return, so you don't overwrite yours. More info
Even then, you should continue to use "their" account for their returns, if you're planning on doing their taxes next year.
Please note that we are unable to merge or delete multiple accounts at this time.
