Q. If I file my taxes and add her as a dependent, will this effect her because she received two economic impact payments (04/15/20 & 01/04/21)
A. No. Those two payments do not have to be paid back because a person's dependency status changed from one year to the next. You do not report her economic impact payments, when filing a 2020 return with her as a dependent.
Q. Will it effect her from receiving any more in the future?
A . No. At least as far as the known 3rd stimulus goes. It's $1400 per person, whether the person gets it herself, or the taxpayer who claims her gets it. If she hasn't received it yet, whoever claims her on a 2020 return will get it. It's not clear when they will get it, it may not be until the 2021 returns are filed.
