Can turbo tax premium online be used to file tax returns for multiple people

[mesquitebean]

No, Online Premium cannot prepare multiple returns.   It can prepare 1 Federal return per account per year.   Each return would need its own separate account and separate fee, if applicable.

Do not try to prepare a second return in the same account, or it will overwrite the first one.

No. You can file one federal return and up to three state returns with TurboTax Online.

TurboTax Online requires a separate account for each person. You will have to create login ID's for each tax return that you prepare.

If you use TurboTax Desktop, you can e-file up to five federal tax returns for multiple people.
