I'm my mom's POA, and I want to do both my taxes and hers. She has no email, so I'll use mine for hers. Can both accounts use the same email address?

I'm my mother's POA, and this is the first time using your service. Are there any special things I  need to do to do someone else's return?

Yes, you are able to use your email address to file both you and your mom's income tax return.
