If the Third Impact Stimulus Payment is based on 2019 AGI (assuming you have not already filed your 2020 taxes) is the IRS going to reissue the difference once you file your 2020 taxes? Many, many Americans will find they have a MUCH lower AGI in 2020 than they did in 2019, due to devastation our country suffered from the global pandemic. I have not seen any guidance from the IRS on this. Anybody else?
