In response to the coronavirus pandemic, then Donald Trump and current Joe Biden's administrations provided low- and middle-income families with stimulus checks.
There were three checks sent out in total, and it doesn't appear that the federal government will send out a fourth one, but there are Plus-Up Payments that are designed to get people caught up on stimulus money they are owed but didn't receive at the time for whatever reason.
Plus-Up Payments are for people who have already received a third economic impact payment based on a 2019 tax return or information from SSA, RRB, or VA and who may be eligible for a larger amount based on their 2020 tax return, according to the IRS. If you qualify, all you have to do now, if you haven't already, is file your 2020 tax return.
