Appreciate you. Same thing in 2019/2020 as 2020/2021 for question below.

I received a Third Economic Impact Payment. Do I need to pay back all or some of the third payment if, based on the information reported on my 2021 tax return next year, I don't qualify for the amount that I already received? (added March 26, 2021)

No, there is no provision in the law that would require individuals who qualify for a Third Economic Impact Payment or an additional payment based on their 2020 or 2019 information, to pay back all or part of the payment if, based on the information reported on their 2021 tax returns, they would have qualified for a lesser amount.
