More on the bill:
It is a refundable tax credit - The check acts like a refund you get in advance. When you file your 2020 tax return, the IRS will compare your income numbers.
If you should have gotten more than you did, you’ll get a refund. If the numbers on your 2020 tax return are different from your 2019 tax return, I don’t expect that you’ll have to pay it back (as the bill is written now). Don’t worry: most taxpayers should get just the right amount.
This is not taxable income.
