the 3rd payment is an advance against 2021 taxes..... so even if your income was $79,000 (presumably for 2020) and the stimulus payment was reduced because of that, what REALLY matters is your 2021 return. If your income ends up being below $75,000 for 2021, you'll get the remainder of the stimulus when you file next year. All is not lost; it's just delayed
and the reverse works to your benefit as well... if 2020 income was below $75,000 (and you get the $1400), but your 2021 income exceeds $80,000, you will NOT be asked to pay it back.
