Hopefully, before the IRS issues its payments, they will check their potential payments against Social Securitys death file and not issue payments to those whose death has been recorded. And the Social Security Administration will check and not issue DUPLICATE payments to those who have already had payments made by the IRS (assuming, of course, that the IRS pays first) and to not issue a payment to someone who had not received a payment from the IRS because of excess income.
yep, all of those things need to be done ... shouldn’t take that many lines of new code to make those kinds of checks for duplicates ...
