So if you are like me and haven't had to file taxes for whatever reason in the past 2 years and have a qualifying child for the extra $500 You need to use the non-filer tool on the IRS website and file .
"Their $1,200 payments will be issued soon and, in order to add the $500 per eligible child amount to these payments, the IRS needs the dependent information before the payments are issued. Otherwise, their payment at this time will be $1,200 and, by law, the additional $500 per eligible child amount would be paid in association with a return filing for tax year 2020.
For people in these groups who have a qualifying child and didn't file a 2018 or 2019 tax return, they have a limited window to register to have $500 per eligible child added automatically to their soon-to-be-received $1,200 Economic Impact Payment. A quick trip to a special non-filer tool on IRS.gov by noon Eastern time, Wednesday, April 22, for some of these groups may help put all of their eligible Economic Income Payment into a single payment."
