I asked this question in another thread and someone posted this, which I was thought was good info:
I've seen a lot of new articles/stories saying the stimulus is based on your 2019 or 2020 income, depending on the latest return filed when the stimulus gets doled out. However, what I've read most places is sorely lacking in completeness.
The bill actually says it's a tax credit for the 2021 tax year, for which you would file your return in 2022.
The advanced payments are based on 2019 and 2020 tax returns.

"Taxpayers receiving an advance payment that exceeds their maximum eligible credit based on 2021 tax return information will not be required to repay any amount of the payment to the Treasury. If a taxpayer’s 2021 tax credit exceeds the amount of the advance payment, taxpayers can claim the difference on their 2021 tax returns."

A: It works like this, we will all ultimately claim a “credit” equal to the stimulus payments we are owed based on our 2021 tax information, on our 2021 tax returns. But to speed up that process, the checks you receive if the bill becomes law will be based on either your 2019 or 2020 tax return.
