If you are using TurboTax CD/Download, you can install it on up to 3 computers. Each individual will have their own return file, which can be password protected. So, as long as people are willing to share computers, then each person can prepare a return without being able to open the other person’s file.

If you are using TurboTax Online, no. You will all have to login to the same account, and anyone who can login has access to all the returns and info.

So, as long as people are willing to share computers, then each person can prepare a return without being able to open the other person’s file.

does above mean people have to share the computer ? 

Yes. You can install TurboTax CD/Download on 3 computers using the same licence, so if you have 5 people, some people are going to have to share a computer. You do something like put your return file on a USB stick and delete it from the computer once you are done with your return, as well as password protecting the file.

Is the 3 maximum installations different from what the US site states as below:

Can I install TurboTax on more than one computer?

You are correct, as indicated in the note of our Microsoft Windows System Requirements "TurboTax may be installed on three computers".  In Canada our software is different from the US.

Thank you for choosing TurboTax.
